Description

Movable container system for treating organic solid waste

Technical Field

The invention belongs to the field of energy and chemical technology, and particularly relates to a movable container system for treating organic solid waste.

Background

Economic growth and changes in the manner of consumption and manufacture are leading to a rapid increase in the production of plastic waste worldwide. Global plastic production has been increasing for over 50 years. Moreover, since plastic is a non-biodegradable material, it remains in the soil and pollutes the environment.

Currently, only 14% of plastic packages are recycled worldwide [ the above data are derived from: https:// www.theguardian.com/substandable-Business/2017/feb/22/plastics-recycling-fish-chemicals-styrofoam-packaging ], about 800 million tons of plastic being discharged into the ocean each year. They are predated or ingested by marine life and birds, seriously affecting their lives. Some plastics can also be combined with industrial chemicals that have polluted the ocean for decades and raised concerns about possible toxins entering the food chain. According to a recent report by the allen macbethur Foundation (Ellen MacArthur Foundation), recycling the remaining 86% of the plastic used for packaging and packaging products at one time can generate revenue in the range of 800 to 1200 billions dollars [ the data is derived from: https:// www.ellenmacarthurfoundation.org/publications/the-new-plastics-environmental-rethinking-the-future-of-plastics ].

Although incineration has been the main waste treatment method so far, the recent increase in the amount and variety of waste has forced policies to shift from simply promoting waste incineration to policies that also promote waste reduction. The amount of waste generated and the amount of waste can be reduced by reusing the waste and recycling it as a resource.

Moreover, the negative environmental impact of emissions from incineration, including atmospheric and soil pollution, is problematic, requiring advanced technologies, particularly to limit the production of dioxins. Currently, 5000 ten thousand tons of common waste (including about 400 thousand tons of waste plastics per year) are produced annually, with about 75% being incinerated. Toxic or harmful emissions associated with incineration are important issues that must be addressed.

The aim of waste-to-energy technology is to treat the potential materials contained in the waste, namely plastics, biomass and rubber tyres, converting them into combustible products, in particular biofuels. As an alternative to incineration technology, thermal cracking technology was developed in the 1970 s, aiming to limit the production of dioxins. Thermal cracking is a simple process, a process that heats organic materials or organics and decomposes them into solids, liquids and gases in an environment with little or no oxygen. The advantage of the thermal cracking process is that it is capable of cracking unsorted and unclean waste plastics/rubbers or other organic solid wastes. In addition, unlike incineration, thermal cracking does not release toxic or harmful emissions to the environment and does not add adverse conditions to further exacerbate an already deteriorating situation over the years.

Comparison of greenhouse gas emissions from thermal cracking processes with other Waste treatment processes [ Sam Haig, et. al Plastic to oil IFM002 final report "Zero Waste Scotland ].]: the emissions associated with the manufacture of other raw materials (excluding waste plastic streams) were 13.0kg CO₂. In the case of thermal cracking, this is due to the hydrogen consumed in the process. The on-site emission of 56kg CO from the incineration of the thermally cracked gas, distillation residue and 3% of the resulting diesel product₂. The emission associated with all transport elements (product and waste) was 197kg CO₂. According to these data, the emission associated with thermal cracking was 266kg CO₂. The emission savings associated with the production of alternative fossil diesel is 426kg CO₂. Overall, the net emission of thermal cracking was-160 kg CO₂。

The waste plastic raw materials mainly come from waste mixtures of plastic products such as Polyethylene (PE), polypropylene (PP), Polystyrene (PS), polyvinyl chloride (PVC) and the like in daily life, such as agricultural films, food packaging bags, engineering waste plastic products or mixed waste plastics selected from domestic garbage landfill sites and the like; the waste rubber raw material mainly comes from the waste of rubber products such as Natural Rubber (NR), Styrene Butadiene Rubber (SBR), Butadiene Rubber (BR) and the likeMixtures such as waste tires, rubber shoe soles, rubber parts and the like; under normal conditions, the decomposition temperature of Polyethylene (PE) is about 265 ℃, the decomposition temperature of polypropylene (PP) is 350-400 ℃, the decomposition temperature of Polystyrene (PS) is about 300 ℃, the decomposition temperature of polyvinyl chloride (PVC) is 150 ℃, and Natural Rubber (NR) is rapidly decomposed at 270 ℃; the butyl Chloride Rubber (CR) is decomposed at 230-260 ℃; waste plastics are a mixture of various plastics such as PE, PP, PS, PVC, etc., waste rubber is a mixture of various rubbers such as NR, SBR, BR, CR., etc., some plastics (such as PE, PVC) or rubbers (such as CR) and the like can be thermally cracked or depolymerized at a lower temperature, and other plastics (such as PP) or rubbers (such as NR) and the like can be effectively and completely thermally decomposed at a higher temperature; other organic solid wastes are derived from municipal domestic wastes, agricultural and forestry wastes, and partial industrial wastes, mainly including paper, kitchen wastes, biomass, industrial sludge and the like. Other organic solid wastes are mainly composed of C, H, O and other elements, and in addition, N, S and other trace elements are also contained; meanwhile, compared with coal, the carbon content of other organic solid wastes is lower, and the H/C and O/C ratios are quite high, so that the organic solid wastes have higher volatile content, but the calorific value is lower than that of common coal, and the characteristics determine that the other organic solid wastes are more suitable for gasification. At the temperature of 200 ℃ below 120 ℃, other organic solid wastes are heated and dried and volatilize water and organic substances; at the temperature of 300 ℃ and 500 ℃, most organic substances are completely thermally cracked and volatilized into thermal cracking gas, part of the thermal cracking gas can be condensed into bio-oil, and non-condensable combustible gas mainly comprises CO and H₂、 C₂H₂、 C₂H₄And the like.

The oils obtained by thermal cracking of plastic wastes and rubber products are generally dark brown or black in color and their odor is very unpleasant. The composition of the thermal cracking oil is complex by analysis, as it also contains alkanes, aromatics and alkenes, aldehydes, ketones, carboxylic acids, sulfides and other impurities. Due to the high impurity content, the value of the crude thermal cracked oil is low and its combustion may even affect the life of the heavy oil burners. Therefore, further processing is necessary to improve the quality. The process of refining thermally cracked oil is essential for producing high quality primary diesel type fuels. Primary diesel fuel is used in a variety of applications, such as powering various agricultural equipment, heavy trucks, road construction equipment, marine vessels, diesel generators.

The traditional thermal cracking system or crude oil refining system has large treatment capacity, but needs fixed places, large investment, large equipment and large occupied area, and cannot be moved at will. The waste raw materials to be treated need to be collected, transported, stored and transported to the factory in large quantities to meet the raw material supply in continuous production, and the larger the scale of the factory is, the larger the radius of the raw material collection is, and the higher the raw material collection and transportation cost is. Such conventional thermal cracking systems or crude oil refining systems are obviously not suitable for remote areas, tourist areas, islands, communities, villages, etc.

Detailed Description

The invention is further described with reference to the following figures and examples.

A movable container system as shown in figure 1, which is used for processing waste plastics/rubber and other organic solid wastes

As shown in fig. 1, waste plastics/rubber or other organic solid wastes, etc. are first subjected to preliminary treatments such as rough breaking, metal recovery, mechanical dehydration, drying, crushing, etc. and then compacted into small pieces. These pieces are then fed to a thermal cracking reactor 2.

It is well known that plastics decompose into oil and gas when heated to 200 to 400 ℃ in the absence of air (oxygen). The thermal cracking process varies greatly depending entirely on the type of plastic and the thermal cracking temperature. For example, polyvinyl chloride (PVC) initially begins to decompose at around 200 to 250 ℃, producing hydrogen chloride, hydrocarbons (gases and liquids) and solid residues at 350 ℃. While most polymers start to decompose at 250 to 450 ℃, the thermal cracking temperature and quality change of various plastics as shown in FIG. 2 [ Katsuhiro Nakanoh, Shizuo Hayashi, Kiyonori Kida, Water Treatment Using introduction-Heated Pyrolysis, Vol. 47 number 3 FUJI ELECTRIC REVIEW ].

In the present invention, the thermal cracking heating process is started without oxygen or with a very small amount of oxygen, and according to a preferred embodiment, the above-mentioned raw materials are heated to 500 ± 50 ℃. Other organic solid wastes are gradually decomposed into inorganic substances, combustible gases, biochar and liquid compounds (including thermal cracking oil); while the waste plastics/rubber will gradually change into thermal cracking oil, combustible gas and slag.

The pyrolysis gas is one of the main products after the thermal cracking treatment of other organic solid wastes. In the high-temperature thermal cracking reaction kettle 2 at about 500 ℃, gas generated by thermal cracking of most organic components in other organic solid wastes is mainly composed of H₂、CO、CH₄、CO₂、C₂H₄、C₂H₆The composition of these six components, the thermal cracking temperature and the chemical composition of the material directly affect the amount of each component. The combustible part in the gas can be stored after being purified and purifiedOr for combustion to generate electricity or for heating. The gas can be safely discharged after being combusted.

The plastics used in the present invention are mixed components obtained, for example, from waste collection. These mixed components include, for example, polyethylene, polypropylene, polyvinyl chloride, polystyrene, polymer blends such as ABS and polycondensates. Among the raw materials which can be used are plastics production waste, industrial and commercial plastics packaging waste, and residues, mixed and pure components of the plastics processing industry, where the requirements for the chemical composition of the plastics waste are not high for the applicability of the invention, and also elastomers, industrial waste rubber products or suitably comminuted used tires and other organic solid waste. Due to the wide variety of waste plastics, the waste plastics cannot be completely and thoroughly classified during sorting, and a small amount of PVC exists in the waste plastics. The PVC has poor stability to light and heat. The softening point was 80 ℃ and decomposition started at 130 ℃. Under the condition of not adding heat stabilizer, the polyvinyl chloride begins to decompose at 100 ℃, and the decomposition is faster at the temperature of more than 130 ℃. During thermal cracking, at high temperatures (around 350 ℃), PVC undergoes dehydrochlorination to release hydrogen chloride and form conjugated polyenes. Hydrogen chloride gas is a residual irritant and corrosive gas, which can severely corrode metal equipment. If the thermal decomposition products of polyvinyl chloride in the raw materials are not dechlorinated, the thermal cracking equipment is severely corroded. Dechlorination and neutralization of HCl are achieved by a dechlorination tank 18 which is tightly connected to the thermal cracking reactor 2. The dechlorination tank 18 can be filled with solid alkaline desiccant or 10-20wt% NaOH solution or other alkaline solution to achieve the same effect. The dechlorination tank 18 is made of high temperature resistant and corrosion resistant titanium alloy or ceramic.

The cracked gas after passing through the dechlorination tank 18 enters a stainless steel gas-water separation tank 19. The gas-water separation tank 19 is effective in removing water and some impurities entrained in the feedstock and separating heavy oil from light oil. After separation, the water, impurities and heavy oil are collected. The separated heavy oil and impurities can be mixed with the newly added raw materials and then enter the next thermal cracking to increase the oil yield.

The high temperature resistant centrifugal induced draft fan 28 introduces the thermal cracking light oil gas into the heat exchanger for condensation. The heat exchanger used in the present invention is an air-cooled box type condenser 30. Inside the air-cooled box type condenser 30, a large amount of combustible compounds in the oil gas are condensed into thermal cracking crude oil. The dissolved water in the thermal cracking crude oil can also be condensed therein. Condensed water is collected, stored and recovered, and non-condensable gas can be collected after water sealing for combustion power generation or other purposes; the non-condensable gas can be safely discharged after being combusted.

After completion of the thermal cracking reaction, carbon black and ash remain in the thermal cracking reactor 2. The ash can be used as an additive of building materials. Traditionally, carbon black has been used as a reinforcing agent in tires. Today, the use of carbon black has expanded to include pigmentation, Ultraviolet (UV) stabilizers, and electrical conductors, among others, because of its unique characteristics.

Since thermal cracking oils are complex mixtures of aliphatic, aromatic and polar compounds, the boiling point is approximately between 70 ℃ and 400 ℃. Thus, it is difficult to find a possible application for direct combustion without purification. Therefore, the crude oil obtained from the thermal cracking reaction can be pumped into a crude oil rectifying kettle 47 in a crude oil refining system 46, the rectifying process is controlled to be carried out at 250-300 ℃, and the temperature of 290-300 ℃ is adopted for rectifying in the invention. Then, the evaporated crude oil vapor is separated by using a stainless steel vapor-water separation tank 19 corresponding to the crude oil rectifying still 47, and water/heavy oil/impurities and the like are separated therefrom. After separation, water, impurities and heavy oil are collected, and the separated heavy oil and impurities can be mixed with newly added raw materials and then enter the next thermal cracking to increase the oil yield. Then the oil gas is introduced into an air-cooled box type condenser 30 by a high-temperature resistant centrifugal induced draft fan 28 for condensation; after that, the condensed oil is filtered in two stages and finally becomes primary diesel oil. The distillation and purification of crude oil have a mass loss of about 10%. The non-condensable gas can be collected after being sealed by water and used for combustion power generation or other purposes, and the non-condensable gas can be safely discharged after being combusted.

Thermal cracking system with two, 20 or 40-size standard container size

In fig. 3, there is a thermal cracking system 1 for processing waste plastics/rubber and other organic solid wastes with a size of 20 or 40 feet standard container, a horizontal thermal cracking reaction kettle 2 made of ferrite or martensitic stainless steel, and an external thermal insulation layer is arranged outside the thermal cracking reaction kettle 2. The thermal cracking reaction kettle of the 20-foot standard container can contain about 1000 kg of waste plastics/rubber or other organic solid wastes. And about 2000 kg of waste materials can be contained in the thermal cracking reaction kettle of the 40-foot standard container. The thermal cracking reactor 2 is placed on the thermal cracking reactor base 15. The small pieces of waste plastics/rubber or other organic solid wastes first pretreated (steps of rough crushing, metal recovery, dehydration drying, crushing, compacting, etc.) are conveyed to the thermal cracking reactor 2 together with a specific solid catalyst by a material conveyor arranged outside the thermal cracking container 45. The thermal cracking kettle feed door 3 and the thermal cracking kettle rear end door 4 of the thermal cracking reaction kettle 2 are upper half circumference doors which can be opened within the range of 180 degrees. In order to completely seal the thermal cracking reaction kettle 2 and the single-shaft cutting type stirring mechanism 5 in the production process, the lower semi-circumference doors of the thermal cracking kettle feeding door 3 and the thermal cracking kettle rear end door 4 are fixed. The thermal cracking process varies greatly depending entirely on the type of plastic and the thermal cracking temperature. In the invention, the thermal cracking heating process is started under the condition of no oxygen or little oxygen, and the raw materials are gradually heated to 500 +/-50 ℃ at the heating rate of 2-3 ℃/min. The waste plastics/rubber can be gradually converted into thermal cracking oil, combustible gas and slag; while other organic solid wastes are gradually decomposed into inorganic substances, combustible gases, biochar, and liquid compounds (including thermal cracking oil). The heating of the thermal cracking reaction kettle 2 from normal temperature to 500 +/-50 ℃ is provided by a half-circumference high-power electromagnetic heating jacket 13, and the temperature, time, power and the like required by the heating of the electromagnetic heating jacket 13 are accurately controlled by an electromagnetic variable-frequency heating control cabinet 14. In the present invention, the horizontal thermal cracking reactor 2 is stationary and does not rotate. In order to ensure uniform heating of the material in the thermal cracking reactor 2, the single-shaft cutting type stirring mechanism 5 installed in the thermal cracking reactor 2 is rotated slowly and continuously during the heating. The rotation of the stirring component 5 is completed by the cooperation of the stirring component and main components of a mechanical transmission device reduction box 7, a double-row chain wheel coupling 8, an explosion-proof motor 11, two sets of bearing overheating-proof water cooling systems 12 and the like which are connected with the outside. The bearing overheating prevention water cooling system 12 is a water cooler with the capacity of 8 liters, the temperature of a water inlet end is 50-85 ℃, and the temperature of a water outlet end is 2-5 ℃.

After the material is heated in the thermal cracking reaction kettle 2 for 4-5 hours, the waste plastic or rubber in the thermal cracking reaction kettle 2 shows the transition of glass state → high elastic state → viscous state → gas state in terms of macroscopic performance. After the centrifugal induced draft fan 28 of high temperature resistant stainless steel is switched on, the fan is rotatory, because the impeller is fluted design, rotatory lifting force that produces can drive the air flow. Therefore, when oil gas enters the pump body of the high-temperature-resistant stainless steel centrifugal draught fan 28 through the air inlet, the oil gas is stirred in the oil gas, each groove is subjected to vortex type pressurization and one-step circulating pressurization to finally form strong air flow energy, and high-temperature pyrolysis gas generated in the pyrolysis reaction kettle 2 is firstly introduced into the dechlorination tank 18 along the oil suction gas pipeline 16 and the connecting pipeline 17 through the air outlet of the pyrolysis reaction kettle 2. The dechlorination tank 18 is made of high-temperature-resistant corrosion-resistant titanium alloy, and is divided into an upper section, a middle section and a lower section according to the height of the dechlorination tank, the inner part of the dechlorination tank is evenly divided into an upper section, a middle section and a lower section, each section is separated by a high-temperature-resistant corrosion-resistant titanium alloy fine net, and a solid dechlorinating agent is filled on the fine net of each; in the dechlorination tank 18, the pyrolysis gas is in countercurrent contact with an alkaline solid dechlorinating agent to achieve dechlorination effect; the gas extracted from the top of the dechlorination tank 18 then enters the top of a stainless steel steam-water separation tank 19. The steam-water separation tank 19 is a stainless steel helical blade type steam-water separator, and a helical blade type structure is designed in the steam-water separation tank 19; a large amount of high-temperature pyrolysis gas containing liquid components enters a shell of the steam-water separation tank 19 from an inlet direction, and starts to rotate and descend along a spiral channel formed by the inner wall of the shell of the steam-water separation tank 19 and a high-temperature-resistant stainless steel spiral blade, the spiral enables the gas to generate a high-speed centrifugal effect under the guide of the spiral blade, under the synergistic effect of gravity, liquid components with large specific gravity such as heavy oil, water, particulate matters and the like flow to the bottom of the steam-water separation tank 19 along the inner wall of the shell and the stainless steel spiral blade and are discharged by an automatic drainer or discharged at regular time, and clean and dry light oil gas is discharged from an outlet of the steam-water separation tank 19 and is introduced into an air-cooled box type condenser 30 arranged on a top plate outside a container by. The centrifugal draft fan 28 may be installed in front of the inlet of the air-cooled box type condenser 30 as shown in fig. 3, or may be installed at the outlet of the air-cooled box type condenser 30.

After the high temperature oil gas is cooled by the air-cooled box type condenser 30, most of the gas is condensed to become normal temperature oil. The oil flows into a stainless steel crude oil storage tank 35 along a crude oil outlet pipeline 34 for storage. The gas with the minimum amount of non-condensable in the oil gas is automatically discharged from a condenser exhaust pipe 33 in the air-cooled box type condenser 30, the main component of the gas is C1-C4 alkane, in order to eliminate potential safety hazards and avoid the backflow and overpressure of the gas, the gas can be introduced into a power generation device which can be configured outside the thermal cracking container 45 after being processed by a small water-sealed tank which is arranged outside the thermal cracking container 45 and used for combustion power generation. The thermal cracking system 1 is equipped with a ventilation system in addition to a necessary thermal cracking safety alarm system (including pressure abnormity, temperature abnormity, leakage of various toxic and harmful gases, and the like) 43, and cold air inlet in the thermal cracking container 45 is completed by a directional cooling guide fan 37 arranged at the bottom of the rear end wall of the container; because a large amount of heat can be discharged in the thermal cracking production process, the timely discharge of the internal air after absorbing the heat is completed by the box wall negative pressure radiating fans 41 arranged at the top of the rear end wall of the container and the plurality of top negative pressure radiating fans 42 arranged at the top plate of the container. After the thermal cracking process is completed and before the next thermal cracking production, the thermal cracking reaction kettle 2 must be rapidly cooled to about 50 ℃, and the cooling rate is 4-5 ℃/min. While keeping the ventilation system and the high temperature resistant stainless steel centrifugal induced draft fan 28 in the container working continuously, the thermal cracking kettle feeding door 3 of the thermal cracking reaction kettle 2 and the upper semi-circumference door of the thermal cracking kettle rear end door 4 can be opened for ventilation when the residual temperature in the kettle is 200 ℃. The whole thermal cracking process is controlled by the thermal cracking PLC control cabinet 44 of the thermal cracking system 1, and the thermal cracking PLC control cabinet 44 can integrally control the operation of all the facilities and equipment in the thermal cracking system 1. The thermal cracking system 1 is arranged in a 20 or 40 foot standard container 45. After the thermal cracking process is completed, the thermal cracking reactor 2 can be cleaned of the residues such as carbon black and ash by opening the carbon black and ash outlet 36 to connect with a mobile powder industrial dust collector. The collected carbon black can be recycled. The rear door 4 of the thermal cracking kettle can be opened for maintenance in the thermal cracking reaction kettle 2. The thermal cracking kettle rear end door 4 is an upper half circumference door which can be opened within a range of 180 degrees.

Stirring in thermal cracking reaction kettle

The waste plastics or rubber enters the thermal cracking reaction kettle 2 after being sorted and crushed. The thermal decomposition temperature of various waste plastics is different, but basically in the range of 350-500 ℃. The thermal decomposition temperature of the waste rubber is relatively low. Plastics are the most important part of the polymer material, and the yield and the dosage of the plastics account for more than 60 percent of the whole polymer material. The physical and mechanical properties of the plastic are closely related to the temperature, and the stress behavior of the plastic changes when the temperature changes, so that different physical states are presented. With the temperature rise of the thermal cracking reaction kettle 2, the waste plastics or rubber presents three mechanical states of glass state, high elastic state and viscous state on the macroscopic performance, and two changes from the glass state to the high elastic state and from the high elastic state to the viscous state. As shown in fig. 4, the physical states of the waste plastics or rubber that are different when the temperature rises [ plastic modification process, formulation and application/Yangming mountain, Li Lin regular script, etc.. Beijing: chemical industry Press, 2006.05, ISBN 7-5025-8724-1 ].

In FIG. 4, when the temperature is low (T < T)_g) When the molecular motion energy of the polymer is low, the polymer is in a glass state. The thermal kinetic energy of the molecules increases gradually with increasing temperature, and when a certain temperature is reached, the thermal kinetic energy of the molecules is enough to overcome the potential barrier of internal rotation, and segmental motion can be performed, but the whole molecular chain is still in a state of being "frozen". The deformation produced in this state is a reversible high-elastic deformation, called the high-elastic state. When the temperature in the thermal cracking reaction kettle 2 continues to rise, when the heated temperature of the plastics exceeds the viscous flow temperature T_f(the viscous flow temperature is the transition of the polymer from the high-elastic state to the viscous state (or vice versa)In a high elastic state), the center of gravity of the whole macromolecule is relatively displaced (i.e. relative slippage is generated between the macromolecule and the macromolecule) due to the violent movement of the chain segment, and the high polymer shows high viscous flow under the action of external force, which is generally called as melt. The flow deformation is irreversible, and the mechanical state with high viscosity is called viscous flow state, and the viscous flow temperature T_fIncreasing with increasing molecular weight. When the plastic/rubber is continuously heated to the thermal decomposition temperature T_dAt high temperatures, the polymer begins to decompose and discolor and produce a material of relatively small molecular mass.

Generally, the viscosity of low molecular liquid is relatively low, and the viscosity is basically not changed along with the flowing state after the temperature is determined, for example, the viscosity of water is about 1mPa.s at room temperature. The absolute value of the viscosity of non-Newtonian liquid such as high molecular plastic or rubber is generally high when the non-Newtonian liquid is converted into liquid by heating. Zero shear viscosity eta of polymer melt_０Are all at 10²～10⁴In the range of Pa.s, 10 of the viscosity of water⁶The melt viscosity was found to be high. Fluids with a viscosity of less than 5pa.s are generally considered low viscosity fluids; the fluid of 5-50Pa.s is medium viscosity fluid; 50-500Pa.s of a high viscosity fluid. For very high viscosity fluids above 500pa.s, such as plastic or rubber melts as described herein.

In the thermal cracking process of waste plastics or rubber and other materials, when the temperature in the thermal cracking reaction kettle 2 exceeds the viscous flow temperature T of the materials_fIf the thermal cracking reaction kettle 2 is not uniformly stirred and the heat transfer between the kettle wall of the thermal cracking reaction kettle 2 and the material is not uniform, abnormal operation phenomena such as material sticking, agglomeration and even bed death are easily caused, and the normal operation of the thermal cracking reaction kettle 2 is influenced. The slag formation on the inner wall of the kettle body after the thermal cracking reaction frequently encountered in the thermal cracking production industry is caused by the reason that the materials become extremely high-viscosity fluid and then flow smoothly and are heated unevenly. If the kettle body is not cleaned, the slagging on the inner wall of the kettle body becomes thicker and thicker, and the heat conduction is seriously influenced. When the plastic or the rubber is in a viscous state, the viscosity is 1000-10000 Pa.s. To understandIn order to solve the problem of the caking property, the invention introduces a stirring mechanism 5 with a cutting type stirring paddle into the kettle body of the thermal cracking reaction kettle 2. The cutting type stirring paddle is the most tough stirring paddle, and the mixing and dispersion of high-viscosity materials are realized by the combination of shearing, smearing, stretching, folding, compressing, kneading and tearing actions (mainly materials). Due to the robust construction and the special design of the cutting type paddles, the surface of the paddle 6 that participates in the mixing is very wide and robust, thus enabling stable mixing of high viscosity and high load materials with a mixing uniformity of up to 99%.

The single-shaft cutting type stirring mechanism 5 is mainly composed of: the high-power explosion-proof motor comprises a high-power explosion-proof motor 11, a reduction gearbox 7, a cutting type blade 6, a stirring shaft, a shaft sleeve, a bearing seat and sealing assembly, a double-row chain wheel coupler 8, a bearing overheating prevention water cooling system 12 and the like.

A schematic diagram of main parts of the stirring mechanism 5 of the single-shaft cutting type is shown in fig. 5: the stirring mechanism 5 of the invention adopts a single-shaft layout, and the stirring shaft is provided with two sections of alternating spiral cutting type blades 6 with equal length. One of the clockwise blades 6 is twisted clockwise by 180 degrees, the other anticlockwise blade 6 is twisted anticlockwise by 180 degrees, and the diameter of the blades 6 is 700-900 mm, so that the layout can provide sufficient radial and axial mixing. Because the operating temperature in the thermal cracking reaction kettle 2 is high, the two blades 6 are made of high-temperature resistant stainless steel. The rotation of the single-shaft cutting type stirring mechanism 5 and the blades 6 is completed by the reduction box 7, the double-row chain wheel coupling 8 and the explosion-proof motor 11 (11 in figure 3) in a coordinated mode. In addition, in order to prevent the overheating of the bearing of the stirring shaft outside the autoclave 2, two sets of water cooling systems 12 (12 in fig. 3) for preventing the overheating of the bearing of the stirring shaft provide cooling circulation liquid to reduce the temperature.

The layout of the single-shaft cutting type stirring mechanism 5 installed in the thermal cracking reactor 2 is shown in FIG. 6: because the material (waste plastic or waste rubber) filled in the kettle body of the thermal cracking reaction kettle 2 can generate solid → liquid transformation when heated to a certain temperature, so that the volume change is very obvious, a larger space is formed above the kettle body which is almost filled initially, and the liquid level line at the moment is possibly slightly higher than the central axis of the horizontal thermal cracking reaction kettle 2 or is positioned below the central axis of the reaction kettle. If the stirring shaft of the stirring mechanism 5 is arranged along the central axis position of the thermal cracking reaction kettle 2, after the material is heated to be liquid, the paddle 6 can not contact the material in the circumferential motion, so that the stirring is not uniform, and the efficiency is low. In order to sufficiently stir the molten liquid, the stirring shaft of the entire stirring mechanism 5 is placed below the central axis of the thermal cracking reactor 2, as shown by the position of the stirring member 5 in fig. 6. The circumference of the thermal cracking kettle body 9 of the thermal cracking reaction kettle 2 is as shown in fig. 6, the maximum circumferential motion range of the blades 6 should be as close as possible to the inner wall kettle bottom of the thermal cracking kettle body 9, as shown by the dashed lines in fig. 6, the outer edges 10 of the blades are shown, such an arrangement can enable the materials to be sufficiently stirred in both solid and liquid states; the clearance between the outer edge 10 of the paddle and the bottom of the inner wall of the thermal cracking kettle body 9 of the thermal cracking reaction kettle 2 is 8-10 mm.

Fourth, industrial electromagnetic heating system

The traditional heating methods of various chemical reaction kettles basically adopt fuel oil, fuel gas, resistance wires, biofuel or other indirect heating, almost all heating methods realize heat transfer by utilizing the principle of temperature difference, and the traditional heating methods can lose a lot of heat energy in the heat transfer process on the one hand, and the production efficiency of equipment is reduced because the size of temperature difference can influence the heating speed on the other hand. In the traditional plastic thermal cracking process, materials are subjected to thermal cracking at a relatively high temperature, the outer wall of the thermal cracking reaction kettle 2 is usually directly heated at the high temperature, the materials on the inner wall of the thermal cracking reaction kettle 2 are heated discontinuously, and the temperature difference between the inner side and the outer side of the kettle wall of the thermal cracking reaction kettle 2 is large, so that the temperature of the outer wall of the thermal cracking reaction kettle 2 is high, and the thermal cracking reaction kettle 2 is easily damaged by high temperature and deformed; the inner wall raw material of the thermal cracking reaction kettle 2 is easy to be locally overheated to generate coking, which affects the oil product generation rate and the equipment service life, and the heat transfer effect is poor.

In the present invention, the electromagnetic heating thermal cracking reaction kettle 2 and the crude oil rectifying kettle 47 are adopted. Electromagnetic heating has the following advantages: in the induction heating process, the energy is transmitted in the form of electromagnetic waves, so that the kettle body of the thermal cracking reaction kettle 2 directly generates heat, and the induction heating process has the advantages of small interference from the outside, less energy diffusion, less heat loss and high heating efficiency. The effective rate of energy utilization is more than 95%, and compared with the common heating by an electric heating ring and an electric heating tube, the electromagnetic heating can save more than 30% of electric energy; because the heating is free of smoke dust, waste gas, peculiar smell and the like and the emission of harmful gas, the pollution to the operation environment is avoided, and the heating device belongs to an environment-friendly heat source; and automatic control is easy to realize. The parameters of the heat source in the processing process mainly comprise the power and the frequency of a power supply, the two electrical parameters are easy to realize automatic control in the control process, a related conversion module is not needed, and the processing quality can be controlled more effectively; the heating speed is high. Because the induction heating process is mainly realized by means of current induction diathermy and conduction, the material can be heated to the expected temperature in a short time and the temperature of the heated material can be accurately controlled; because the heating temperature is not concentrated like the traditional open fire, the oxidation of the kettle body equipment is small, and the service life of the kettle body equipment is greatly prolonged; the electric isolation between the heating body and the main circuit is realized, the electric leakage phenomenon caused by insulation damage is avoided, and the safety is greatly improved; because no open fire or explosion exists, the method is safe.

The heating of the thermal cracking reaction kettle 2 in the invention adopts a half-circumference high-power electromagnetic heating sleeve 13, which is a device for converting electric energy into heat energy by utilizing the electromagnetic induction principle. The electromagnetic controller rectifies 220V/380V and 50/60Hz alternating current into direct current through the rectifying circuit, the direct current is converted into high-frequency high-voltage electricity with the frequency of 20-40KHz through the control circuit, the high-frequency high-voltage electricity with high speed change flows through the coil to generate an alternating magnetic field with high speed change, and countless small eddy currents are generated in a metal body when alternating magnetic lines of force in the magnetic field pass through magnetic conductive metal (iron, cobalt and nickel) materials, so that the metal material can automatically heat at high speed, and the purpose of heating the metal material is achieved. The semi-circumference high-power electromagnetic heating jacket 13 uses a transformer with 380V voltage, comprises one or more high-power main machines driven in parallel, and is several meters long with a section of 50mm²Or 70 mm²The induction line, the MCU control unit, the wire coil bracket, the heat-insulating layer and the like。

In the present invention, the material (waste plastic, waste rubber or other organic solid waste) filled in the thermal cracking reaction kettle 2 is heated to a certain temperature, and then the solid → liquid transition occurs, so that a significant volume change occurs, and a large space is formed above the kettle body which is almost filled initially. In order to avoid the situation that the upper part of the kettle body of the thermal cracking reaction kettle 2 has no material in the later stage of the thermal cracking reaction and is continuously heated, so that overheating can be caused, in the invention, the semi-circumference electromagnetic induction coil of the electromagnetic heating sleeve 13 is only arranged on the outer semi-circumference surface of the kettle body from the bottom of the kettle body of the thermal cracking reaction kettle 2, and then the whole thermal cracking reaction kettle 2 is heated according to the principle that heat is always transferred upwards when the lower half part of the kettle body is heated, so that the use and energy consumption of the electromagnetic induction coil are reduced, and the overheating at the top of the kettle body is avoided. According to the same principle, when crude oil is rectified in the crude oil rectifying still 47, the outside of the still body is also heated by the semi-circumference high-power electromagnetic heating jacket 13. A half-circumference electromagnetic induction coil is shown in fig. 7.

According to past practical experience, ferrite or martensitic stainless steel is used as conductive metal to manufacture the kettle bodies of the horizontal cylindrical thermal cracking reaction kettle 2 and the crude oil rectifying kettle 47, then an insulating layer with the thickness of about 5 cm is arranged on the outer surface of the kettle body, and then high-temperature cloth is used for wrapping the outer surface of the kettle body. Then, arranging a half-circumference electromagnetic induction coil as shown in fig. 7 on the outer surface of the heat insulation layer, wherein the density and the number of turns of the coil are determined according to the temperature and the heating power required by induction; then an outer casing material (such as high-temperature cloth) is used for rigidly fixing multiple points of the semi-circumference electromagnetic induction coil to form an electromagnetic heating sleeve 13, and the electromagnetic heating sleeve directly carries out induction heating on the reaction kettle body, so that materials in the kettle body, such as waste plastics/rubber or other organic solid wastes, can be heated, and the heating temperature is controlled through a far infrared temperature analyzer and intelligent temperature control equipment, thereby obviously improving the heat energy utilization rate and accurately controlling the temperature rise. Because the half-circumference electromagnetic induction coil is arranged outside the reaction kettle body, the heating device cannot be damaged due to high temperature in the reaction kettle. Because no emission is generated in the heating process due to the heating process, the problems of low production efficiency, frequent maintenance of heating elements, environmental pollution and emission caused by combustion and the like of the traditional heating equipment are solved.

Fifth, oil absorption gas pipeline

The hydrocarbon intake conduit 16 in fig. 8 is made of 316 stainless steel. The apparatus is applied at the thermal cracking system 1 in fig. 3 and at the crude oil refining system 46 in fig. 12.

As shown in FIG. 3, when the waste plastics/rubber in the thermal cracking reactor 2 is converted from solid to liquid under electromagnetic heating, the volume of the material is greatly changed, and a certain space is formed at the top of the thermal cracking reactor 2. As the temperature rises, the movement of the molecules increases, and when the temperature rises to a certain point, the molecules of the liquid change from liquid state to gas state and escape from the liquid surface or the inside to the space above the thermal cracking reaction kettle 2. Because the thermal cracking reaction kettle 2 has a certain length, in order to ensure that the oil gas above the thermal cracking reaction kettle 2 is uniformly absorbed, in the invention, three oil pipes vertical to the axis of the thermal cracking reaction kettle 2 are equidistantly arranged on the top of the thermal cracking reaction kettle 2, the number of the oil pipes can be generally determined according to the length of the thermal cracking reaction kettle 2, and the inner diameter of the oil pipes can be determined according to actual requirements. One end of the three vertical oil pipes is hermetically connected with the inner wall of the top of the pyrolysis reaction kettle 2, and the other end is hermetically connected with a larger main oil gas suction pipeline vertical to the three vertical oil pipes, and the main oil gas suction pipeline and the vertical oil pipes form an oil gas suction pipeline 16.

Sixthly, gas-water separation

The stainless steel gas-water separation tank 19 shown in fig. 9 is applied at the thermal cracking system 1 in fig. 3 and at the crude oil refining system 46 in fig. 12. FIG. 9 is a schematic view of the internal structure of the stainless steel gas-water separation tank 19; a large amount of high-temperature gas containing liquid components enters the gas-water separation tank 19 from a medium gas inlet 20 of the separation tank and starts to rotate downwards along a spiral channel formed by the inner wall of a stainless steel shell of the gas-water separation tank 19 and a high-temperature-resistant stainless steel spiral blade 21; the spiral causes the gas to generate high-speed centrifugal action under the guide of the spiral blade 21, and under the synergistic action of gravity, components with large specific gravity such as heavy oil, water, particulate matters and the like flow to the liquid separation plate 25 along the pipe wall and the spiral blade 21 due to the speed reduction, and enter the bottom of the gas-water separation tank 19 after beginning to settle under the action of the liquid separation plate 25. The water is drained or discharged at regular intervals by the automatic drain valve 26. Other impurities may be discharged through the blow-down valve 27. Because the high-temperature gas rotates along the spiral channel to move downwards to form cyclone, low pressure is formed at the axial central gas outlet pipe 22 of the gas-water separation tank 19, and the clean and dry light oil gas with small relative density is gathered at the low-pressure area (gas outlet pipe inlet 23), moves upwards to the medium gas outlet 24 and is discharged.

Seventh, condensation of oil gas

The air-cooled box type condenser shown in fig. 10 is applied at the thermal cracking system 1 in fig. 3 and at the crude oil refining system 46 in fig. 12.

In fig. 10, the high-temperature oil gas is pumped into an air-cooled box type condenser 30 through an air inlet header 29 under the action of a stainless steel centrifugal induced draft fan 28. In the present invention, in order to maximally save the space inside the container and effectively dissipate the heat of condensing high-temperature oil gas, the air-cooled box type condenser 30 is installed on the ceiling outside the container, and is in direct contact with the external environment. The air-cooled box type condenser 30 contains the following main equipment: one or more shell-and-tube condensers 31, one or more air coolers 32 (4 in the present invention), a refrigerant circulation pump, an intelligent computer control system, etc. The intelligent computer control system is installed on the inner wall of the container for convenient operation.

The shell-and-tube condenser 31 is a dividing wall type heat exchanger in which the wall surface of the tube bundle is a heat transfer surface enclosed in a shell. The shell-and-tube heat exchanger is composed of a shell, a heat transfer tube bundle, a tube plate, a baffle plate (baffle plate), a tube box and the like. The shell is cylindrical, the tube bundle is arranged in the shell, and two ends of the tube bundle are fixed on the tube plate. The heat exchange fluid comprises a cold fluid and a hot fluid, wherein one fluid flowing in the tube is called a tube side fluid; another fluid flowing outside the tubes is called the shell-side fluid. To increase the heat transfer coefficient of the fluid outside the tubes, baffles are typically installed within the shell.

For more efficient heat dissipation, the air-cooled box type condenser 30 is equipped with an air cooler 32, and the air cooler 32 is a heat exchange device which is most used as condensing and cooling equipment in petrochemical and oil and gas processing production. The air cooler 32 is mainly composed of three parts, namely a coil, a fan and a shell. The coil pipe of the air cooler 32 is made of aluminum pipe aluminum sheets and steel pipe steel sheets which can be selected. The fins are integral corrugated porous aluminum sheets or steel sheets. In the invention, four high-power special axial flow air coolers are selected as matched fans, the fan has the characteristics of high efficiency, low noise, long service life and the like, and the blades are die-cast aluminum alloy wing type forward-swept twisted blades, the strength is high, and the service temperature is-40-50 ℃.

The circulating liquid for conveying reaction, absorption, separation and absorption liquid regeneration in the device is completed by a refrigerant circulating pump by a pump. To overcome the pressure drop of the circulation system, a low-lift pump may be used.

The high-temperature oil gas is cooled by the shell-and-tube condenser 31 and then condensed into normal-temperature oil, and enters the crude oil storage tank 35 along the crude oil outlet pipeline 34 or enters the pre-filter 54 of the first joint in the duplex filter along the oil outlet pipeline 53. The non-condensable gas in the oil gas is automatically discharged from the exhaust pipe 33 of the condenser, the main component of the gas is alkane of C1 to C4, and the gas can be processed by a small water-sealed tank arranged outside the container and then introduced into a power generation device arranged outside the container for combustion and power generation.

The shell-and-tube condenser 31 of the air-cooled box type condenser 30 can be disassembled for periodic maintenance and cleaning, so as to prevent a small amount of condensed heavy oil accumulated for a long time from partially blocking a pipeline.

Eight, ventilation system in container

The ventilation system shown in fig. 11 is applied at the thermal cracking system 1 in fig. 3 and at the crude oil refining system 46 in fig. 12.

In the invention, in order to keep the ventilation in the container and the safety of operators, all control equipment and safety equipment are placed on one side of the container close to a wall, all operation equipment are placed on the other side of the container, and a channel is formed in the middle and corresponds to a container door. The channel is used for operating personnel and used as an escape channel.

Since the thermal cracking and rectification reactions release a large amount of heat, good ventilation and proper temperature must be maintained in the container for safe operation in the container. During production, the front end door of the container must remain open. The lower part of the rear end wall of the container is provided with a directional cooling guide fan 37, and when the container works, the directional cooling guide fan 37 can guide cold air outside the container into the container; because the front door of the container is opened, air convection is easily formed with the directional cooling induced fan 37.

In addition, the thermal cracking system 1 or the crude oil refining system 46 has air inlets at the side and bottom of each control cabinet. When in use, cold air is absorbed from the air inlet 38 at the bottom of the control cabinet and the air inlet 39 at the side of the control cabinet. In operation, most of the heat from the control cabinet is exhausted to the interior of the container through the top-mounted in-line duct 40. The thermal cracking reaction kettle 2 or the crude oil rectifying kettle 47 can discharge a large amount of heat in the production process, the internal air absorbs the heat and flows to the top, and then the heat is discharged by two box wall negative pressure radiating fans 41 arranged on the upper part of the rear end wall of the container and a plurality of top negative pressure radiating fans 42 arranged on the top plate of the container, so that the equipment in the control cabinet can be ensured to run reliably for a long time.

Since thermal cracking or distillation is not continuous, the temperature in the first vessel needs to be reduced to about 50 ℃. If natural cooling is used, it takes several hours, which is not advantageous in increasing productivity. After thermal cracking or rectification is finished, all ventilation systems and the high-temperature stainless steel centrifugal draught fans 28 in the container are kept to work continuously, and when the residual temperature in the thermal cracking reaction kettle 2 is reduced to 200 ℃ or the temperature in the crude oil rectification kettle 47 is reduced to about 120 ℃, front and rear end doors of the thermal cracking reaction kettle 2 or the crude oil rectification kettle 47 are opened to ventilate until the temperature is reduced to 50 ℃.

Collecting and treating carbon black

The mixture of carbon black and ash, which is generated after the thermal cracking reaction of the organic solid waste in the thermal cracking reaction kettle 2, is mainly deposited at the bottom of the fixed reaction kettle. If the mixture is not cleaned in time, the produced gas is not circulated in the next production process, so that the gas blockage is produced, the pressure in the thermal cracking reaction kettle 2 is continuously increased, and the pressure in the thermal cracking reaction kettle 2 exceeds the standard and the explosion danger is produced; in addition, the newly added catalyst fails due to the fact that the catalyst is poisoned if the surface of the newly added catalyst is surrounded by carbon powder; the mixture of the carbon powder and the ash residue can cause poor oil quality of waste plastics or waste rubber oil refining, and the production cannot be continuous and cannot be industrialized. Therefore, it is desirable to effectively remove the carbon powder and ash mixture from thermal cracking reactor 2 as quickly as possible after each thermal cracking reaction is completed.

The bottom of the traditional thermal cracking reaction kettle 2 is provided with a helical blade pushing and chip removing machine to take the mixture of carbon powder and ash out of the reaction kettle. However, the thermal cracking reactor 2 of the present invention has a large bottom area, is not flat, and has a certain curvature. The blades of the helical blade pushing and chip removing machine can not completely cover the area of the bottom of the kettle in motion, so the ash discharging efficiency of the device is not high, and ash residues are always left at the bottom of the thermal cracking reaction kettle 2.

In order to solve the problem, in the invention, as shown in a carbon black and ash residue outlet 36 in fig. 3, a special flange-type valve port (carbon black and ash residue outlet 36) is reserved on a rear end door 4 of a thermal cracking kettle of a horizontal thermal cracking reactor 2 so as to be convenient for being externally connected with a matched mobile powder industrial dust collector, and a lengthened suction nozzle of the mobile powder industrial dust collector can enter the deep part of the kettle body of the thermal cracking reactor 2 through the flange-type valve port and can freely move; under the action of strong negative pressure difference generated by the high-pressure fan, ash residues near the suction nozzle enter the dust collector along with air flow, the ash and dust pass through the filter in the dust collector, the garbage and the dust are left in the ash storage box, and the air is discharged out of the dust collector after being filtered, so that the whole dust collection whole process in the pyrolysis reaction kettle 2 is completed.

366 kg of crude carbon black is produced as a by-product for every 1 ton of used tires; for every 1 ton of waste plastics, 50-150 kg of crude carbon black is produced. The collected ash can be used as an additive to building materials, and the carbon black can be reused in the following fields: traditionally, carbon black has been used as a reinforcing agent in tires. Today, because of its unique characteristics, the use of carbon black has expanded to include pigmentation, Ultraviolet (UV) stabilizers, and conductive agents in a variety of everyday and specialty high performance products, including:

1. tires and industrial rubber articles: adding thermally cracked carbon black simultaneously to the rubber filler as a reinforcing agent or enhancer; for various types of tires, inner liners, carcasses, sidewalls, and treads, and different types of requirements are used depending on the particular performance.

2. Plastic carbon blacks are now widely used in moldings in products such as conductive packaging, films, fibers, garbage bags, piping and semiconductive cable compounds, industrial bags, photographic containers, agricultural mulch films, stretch packaging and automotive, electrical/electronic, household thermoplastic molding applications for appliances and blow molded containers.

3. Electrostatic discharge (ESD) compounds: well-designed thermal cracking carbon blacks have shifted the electrical characteristics of products such as insulation to conductive electronic packaging, safety applications and automotive parts.

4. High-performance coating: thermally cracked carbon black provides pigmentation, electrical conductivity, and ultraviolet protection and is useful in many coating applications, including automotive (primer) primers and clearcoats), marine, aerospace, decorative, wood, and industrial coatings.

5. Carbon powder and printing ink: thermally cracked carbon black can enhance the formulation and provide a wide range of flexibility to meet specific color requirements.

6. Activated carbon: thermal cracked carbon black has a high iodine absorption value, making it absorb potential adsorbents for water purification and gold recovery.

7. For smelting high-quality non-ferrous metals and cast iron; it is used as carburizing agent for mechanical parts to raise the hardness and wear resistance of steel parts.

8. Mixing with potassium nitrate and sulfur to obtain black powder.

9. Use as a solid fuel: the low calorific value of the carbon is about 25MJ/kg, the carbon is a fuel with a medium calorific value, and the pollution degree after combustion is very low; can be directly used as civil fuel, for baking food, burning food and heating, and can be converted into gas fuel by a gasification furnace; the treated thermal cracking carbon black has higher calorific value, fixed carbon and lower calorific value sulfur and ash content; it can potentially be used as a pellet or high quality fuel briquette.

Crude oil refining system with standard container size of ten, 20 or 40 feet

In fig. 12, in a crude oil refining system 46 with a size of 20 or 40 feet and a standard container, a horizontal crude oil rectifying still 47 is made of ferrite or martensitic stainless steel, an external heat insulation layer is arranged outside a crude oil rectifying still 47 body, and 1500 liters of crude oil made of waste plastics/rubber or other organic solid wastes can be contained in the crude oil rectifying still 47 configured in a 20 feet standard refining container 60. And 3000 liters of crude oil made of waste plastics/rubber or other organic solid wastes can be contained in the crude oil rectifying still 47 configured in the 40-foot standard refining container 60. The crude oil rectifying still 47 is placed on the rectifying still base 51. Raw material crude oil can be pumped into the crude oil rectifying still 47 by an oil pump from a crude oil feed port 49 at the front end of the crude oil rectifying still 47. The rectification needs to gradually increase the temperature of the crude oil from normal temperature to 200-350 ℃, preferably 250-300 ℃, and the temperature rise rate is 1-1.5 ℃/min. In the invention, the rectification is carried out at 290-300 ℃. The temperature rise of the crude oil rectifying kettle 47 is provided by a semi-circumference high-power electromagnetic heating jacket 13, and the temperature, time, power and the like required by heating are accurately controlled by a corresponding electromagnetic variable-frequency heating control cabinet 14. The centrifugal induced draft fan 28 of the high temperature resistant stainless steel utilizes the lifting force generated by the rotation of the impeller to introduce the high temperature oil gas generated in the crude oil rectifying still 47 into the gas-water separation tank 19 made of stainless steel along the corresponding oil absorption gas pipeline 16 and the connecting pipeline 17. The gas-water separation tank 19 is a stainless steel helical blade type steam-water separator, a helical blade type structure is designed in the device, a large amount of gas-liquid mixed medium containing liquid components enters the shell of the device from the direction of a medium inlet 20 of the separation tank, starts to rotate and descend along a helical channel formed by the inner wall of the shell and a high-temperature resistant stainless steel helical blade 21, and the helix leads the gas to generate high-speed centrifugation under the guidance of the helical blade, under the synergistic action of gravity, liquid components with large specific gravity such as heavy oil, water, particulate matters and the like flow to the gas-water separation tank 19 along the pipe wall and the helical blades 21 due to the reduction of speed and are discharged by the automatic drain valve 26 or are discharged at regular time by the blow-down valve 27, clean and dry light oil gas is discharged through the medium gas outlet 24 and is introduced into the air-cooled box type condenser 30 arranged on the top plate outside the refining container 60 through the stainless steel centrifugal induced draft fan 28 and the air inlet header 29. The induced draft fan 28 can be installed in front of the inlet of the air-cooled box type condenser 30 as shown in fig. 12, or can be installed at the outlet of the air-cooled box type condenser 30. The non-condensable gas in the oil gas is automatically discharged from a condenser exhaust pipe 33 of the air-cooled box type condenser 30, the main component of the gas is C1-C4 alkane, and in order to eliminate potential safety hazards and avoid the backflow and overpressure of the gas, the gas can be treated by a small water-sealed tank arranged outside the refining container 60 and then introduced into a power generation device which can be matched outside the refining container 60 for combustion power generation.

The high temperature oil gas is cooled by the air-cooled box type condenser 30 and then condensed into normal temperature oil. From the oil outlet line 53, the oil enters a duplex strainer formed by a first prefilter 54 and a second fine filter 56. Under the driving of the oil pump 55, the primary diesel oil filtered by the first pre-filter 54 and the second fine filter 56 is delivered to a stainless steel primary diesel oil storage tank 57 at the tail end of the crude oil refining system 46 by another oil pump 55 for storage. In the whole rectification process, the dynamic change of the crude oil liquid level in the crude oil rectification kettle 47 can be detected by the real-time radar wave sent by the high-temperature resistant radar liquid level meter 52 arranged at the top of the crude oil rectification kettle 47 so as to judge whether the rectification process is successfully completed.

Crude oil refining system 46 is equipped with a ventilation system in addition to the requisite refining safety alarm system 58 (including pressure anomalies, temperature anomalies, leaks of various toxic and harmful gases, etc.). The cold air intake in the refining container 60 is completed by a directional cooling induced fan 37 arranged at the bottom of the rear end wall of the refining container 60. Because a large amount of heat can be discharged in the rectification production process, the internal air can be discharged in time after absorbing the heat by the tank wall negative pressure radiating fans 41 arranged at the top of the rear end wall of the refining container 60 and the plurality of top negative pressure radiating fans 42 arranged at the top plate of the refining container 60. The whole rectification process is controlled by a refining PLC control cabinet 59. The refining PLC control cabinet 59 may integrally control the operation of all of the facilities and equipment in the crude oil refining system 46. The crude oil refining system 46 is disposed within a 20 foot or 40 foot standard refining container 60. After the rectification process is completed, the cleaning of the residue in the crude oil rectification tank 47 can be completed by opening the rectification tank rear end door 50. Before the next round of rectification, the crude oil rectification kettle 47 must be cooled to about 50 ℃. And when the ventilation system in the container and the stainless steel high-temperature resistant centrifugal induced draft fan 28 continuously work, the front end door 48 and the rear end door 50 of the rectifying still can be opened and matched for ventilation when the residual temperature in the crude oil rectifying still 47 reaches 120 ℃. The diameters of the front end door 48 and the rear end door 50 of the rectifying still are slightly smaller than the diameter of the body of the crude oil rectifying still 47, and the front end door and the rear end door can be opened completely, so that operators can work conveniently.

Eleven, filtration of the rectified oil

The duplex filter is formed by connecting two stainless steel filters and can be a single-bag parallel duplex filter or a filter element serial duplex filter. The invention adopts a filter element series connection type duplex filter. The filter element tandem type duplex filter adopts two sets of cylindrical or corrugated stainless steel sintered filter elements, and the stainless steel sintered filter elements have the advantages of excellent and uniform filtering precision, small filtering impedance, high mechanical strength, good wear resistance, heat resistance and cold resistance, easy cleaning and the like, and are widely applied to the field of petrochemical industry.

The filtering precision of the filter element adopted by the fine filter 56 is 5-40 mu m, and the fine filter can effectively remove smaller impurities in the oil. The flow of oil from the first prefilter 54 to the second fine filter 56 is driven by an oil pump 55. The primary diesel oil filtered by the second fine filter 56 is sent by another oil pump 55 to a stainless steel primary diesel oil storage tank 57 at the end of the crude oil refining system 46 for storage.

The gas in the oil gas is exhausted automatically through the exhaust pipe 33 of the condenser, and the non-condensable gas after safe treatment can be introduced into a power generation device arranged outside the thermal cracking container 45 for combustion power generation. After the first kettle is produced, in the process of quickly cooling the thermal cracking reaction kettle 2, a ventilation system and a stainless steel high-temperature resistant centrifugal induced draft fan 28 in the thermal cracking container 45 keep continuously working. When the residual temperature of the thermal cracking reaction kettle 2 is reduced to 200 ℃, the upper semi-circumference doors of the feeding door 3 and the rear end door 4 of the thermal cracking kettle can be opened to be matched with other ventilation facilities in the thermal cracking container 45 for rapid temperature reduction. When the thermal cracking reaction kettle 2 is rapidly cooled to about 50 ℃, the feeding door 3 and the rear end door 4 of the thermal cracking kettle are closed, and the centrifugal induced draft fan 28 is closed. The cleaning of the residue such as carbon black and ash in the thermal cracking reactor 2 can be accomplished by opening the carbon black and ash outlet 36 and connecting to a mobile powder industrial dust collector. The collected carbon black can be recycled.
