Description

The group of inventions relates to means for processing carbon-containing raw materials and can be used in communal, agricultural, wood processing, mining and petrochemical industries for the thermochemical processing of low-quality fuels and carbon-containing waste from these industries in order to produce combustible gas, solid and liquid fuels, sorbents and etc.

A known installation of thermochemical processing of organic raw materials into fuel components, containing a reactor equipped with devices for loading raw materials into it and unloading the solid component of its thermochemical processing, installed respectively in the upper and lower parts of the reactor, the outlet located in the upper part of the reactor for the removal of the gas-vapor component of the processing of raw materials ( gas), moreover, the reactor is equipped with at least two ring collectors for introducing into its working space a gaseous coolant, conduction device located outside the reactor. The gas-vapor outlet of the reactor is connected with the gas-vapor separation system, which is made in the form of a series of sequentially connected separation apparatuses for producing fractions of liquid hydrocarbons from steam gas, each of the separation apparatuses is connected to one of the outlets with a storage capacity, the last of the separation separators installed in series, connected to a separator through a heat exchanger providing separation of liquid and gaseous phases of steam and gas. (see RF patent No. 2275416, class C10L 5/48, 2006).

As a result of the analysis of the known installation, it should be noted that the need for portioned heating of the fuel and removal of oxygen from it causes periodic loading of fuel into the reactor, which reduces the productivity of the installation compared to continuous loading, and the resulting cyclic mode of operation of the reactor affects the quality of the products. Isolation of the vapor-gas phase obtained in the reactor with the solid phase present in it also reduces the quality of the products obtained. In addition, the use of the obtained liquid fraction and fuel gas to obtain a coolant as fuel reduces the yield of finished products.

A known installation for the thermochemical processing of carbon-containing raw materials containing a vertically mounted thermochemical pyrolysis reactor equipped with means for loading raw materials and technological additives in its upper part, a gas generator designed to produce a gaseous coolant, equipped in the upper part with a raw material loading device, and a collector connected to the blower in the lower part for supplying heated air to the cavity of the gas generator and a device for unloading ash from the gas generator, moreover, gas the herator is connected to the reactor by an air channel (pipeline) for supplying to the reactor cavity the heat carrier obtained in the gas generator — hot generator gas. In the reactor vessel, according to its height, shelves made of mesh material are slanted, with an inclination downward from the walls of the reactor to its center, the upper part of the reactor, in relation to its other parts, has an increased cross section, and in the lower part of the reactor there is a hopper for collecting pyrochol, under which there is a device for unloading pyrochol from the rector, made in the form of a screw, along which heat-removing plates are laid, the screw and plates are placed in a casing, the cavity of which is built into the air channel connecting the blower and a gas generator manifold.

The installation is additionally equipped with a device for purifying the solid phase obtained in the reactor from the solid phase and a device for separating the combined gas and vapor from the output connected to its output, while the device for cleaning the solid phase obtained in the reactor from the solid phase is made in the form of a separator and is connected to the gas outlet of the reactor in its upper part. (see RF patent No. 2632812 class. C10L 5/48, 2015) - the closest analogue.

As a result of the analysis of the known installation, it should be noted that for its effective operation it is necessary to use finely ground raw materials with low moisture content and tarry and fusible materials for feeding into the reactor, which significantly limits the range of raw materials used and significantly increases the cost of its preparation for processing. It is very significant that the time spent by the processed raw material in the reactor cavity during its processing is very limited, due to its movement from top to bottom along the inclined shelves during processing, as well as to the limited possibilities for regulating the angle of inclination of the shelves and the size of their mesh cells.

All this does not allow for the processing of the entire mass of raw materials, the remains of which, together with pyrochol, are removed from the reactor, significantly reducing the quality of pyrochar.

When viscous components appear in the processed raw materials under the influence of temperature, plugs from raw materials form and gradually grow on the grids of the reactor shelves, which, in addition to the deterioration in the quality of the obtained pyrolysis products, necessitates periodic shutdown of the reactor for cleaning, which significantly reduces its productivity. The use of heat discharged from the reactor pyrochol for heating the air injected into the gas generator is inefficient, since such coal already has a low temperature.

The technical result of this group of inventions is the development of options for plants characterized by universality, due to the processing of a wide range of raw materials, including coarse, with a high degree of moisture and impurities, high productivity, by creating optimal conditions for loading raw materials, their processing during all the time spent in the reactor, as well as obtaining the target products (pyrochol, steam and gas, etc.) of high quality due to the high degree of processing of raw materials and purification received in the reactor combined-cycle gases.

The specified technical result is achieved by the fact that in the installation for the thermochemical processing of carbon-containing raw materials containing a reactor for pyrolysis of raw materials, a device for loading raw materials and technological additives into the reactor to be pyrolyzed, a gas generator designed to produce a gaseous coolant, equipped with devices for loading raw materials and unloading ash, as well as a gas outlet connected to the cavity of the reactor for supplying the obtained coolant to the reactor, a blower, the outlet of which is connected by a pipe to the The gas generator’s ability, as well as the device for cleaning the combined gas and steam obtained in the reactor, connected with the outlet gas channel of the reactor, and the gas and vapor separation apparatus, is new in that the installation is equipped with a heat exchanger connected to the inlet to the gas outlet of the reactor and the outlet to the inlet of the gas and gas separation apparatus, to the outlet of which is connected to a smoke exhauster, the air supply pipe from the blower to the gas generator is passed through the heat exchanger, the reactor is made in the form of a shell and upper and lower shells covering the shell along its t rtsam, the shell is mounted obliquely and equipped with a mechanism for its rotation relative to the housings fixed against rotation, on the upper case there are channels for introducing raw materials and technological additives, as well as coolant into the cavity of the reactor, and channels for removing steam and gas and pyrocarbon in the lower case, with by agitators of the raw material placed in the reactor, made in the form of plates attached longitudinally to the inner surface of the shell, and on some agitators, shelves are made at an angle of 90 ° to the plane of the plate, while The agitators with shelves installed in the cavity of the shell alternate with the agitators without shelves, and a start-up torch can be mounted on the upper casing to heat the cavity of the shell before starting the reactor.

In an embodiment of a thermochemical processing plant for carbon-containing raw materials containing a reactor for processing raw materials, a device for loading raw materials and technological additives into the reactor to be processed, a pipeline connected to the reactor cavity connected with the outlet of the blower, and also a device for cleaning the combined-cycle gases obtained in the reactor associated with the gas outlet The channel of the reactor, and the gas-vapor separation apparatus, is new in that the installation is equipped with a heat exchanger connected to the input to the output of the floor cleaning device of steam and gas gases in the reactor, and the outlet — with the input of the gas-vapor separation apparatus, to the outlet of which a smoke exhauster is connected — an air supply pipe is passed through the heat exchanger into the reactor, which is made in the form of a shell and upper and lower housings covering the shell along its ends, the shell is mounted obliquely and it is equipped with a rotation mechanism relative to the housings fixed against rotation; on the upper case, channels are made for introducing into the reactor cavity raw materials and technological additives, as well as air pumped through a pipeline with a blower, and at the bottom - channels for the removal of combined-cycle gases and pyrocoal, while the reactor is equipped with agitators

placed in the reactor raw materials, made in the form of plates attached longitudinally to the inner surface of the shell.

Disclosed below in the description of the installation relate to an object of the same type, the same purpose and provide the same technical result, that is, are options.

The essence of the claimed group of inventions is illustrated by graphic materials on which:

- in FIG. 1 is a diagram of an installation for thermochemical processing of carbon-containing raw materials;

- in FIG. 2 - reactor, cross section;

- in FIG. 3 - profile of agitator.

The thermochemical processing plant for carbon-containing raw materials contains a gas generator 1 equipped with a device (not shown) for loading the raw material, as well as a device (not shown) for delivering a solid product of its processing - ash and an outlet (not indicated by) for the removal of the obtained coolant - hot generator gas. The gasifier cavity is connected by a pipe (not indicated by position) to the blower 2, designed to supply air to the gas generator cavity 1. The pipe for supplying air from the blower 2 to the gas generator is passed through the heat exchanger 3, which ensures heating of the air supplied to the gas generator 1.

To obtain a coolant, a standard vortex gas generator or a standard layered gas generator can be used. A vortex gas generator is most appropriate to use when the feedstock has a particle size of less than 10 mm and a moisture content of less than 15%. A layered gas generator is most appropriate to use when the feed has a particle size of more than 10 mm and a moisture content of more than 15%. A specific model of the gas generator 1 is selected in a known manner, based on a given performance on the coolant.

The ash obtained during operation of the gas generator is removed from it in a known manner, for example, by means of a lock gate.

The installation also contains a reactor for thermochemical pyrolysis of raw materials, made in the form of a shell 4 with an outer diameter d1 mounted on support rollers 5 mounted on fixed supports 6. The shell 4 is located on the rollers obliquely relative to the horizontal at an angle of 3-8 °.

The reactor also contains two bodies 7 (upper) and 8 (lower), covering the shell 4 at its ends. The shell and the housing are docked hermetically, and the shell has the ability to rotate relative to the buildings, which are fixed from rotation. The tightness of the cavity of the shell 4 is provided by the seals 9. The seals 9 are most expediently made of heat-resistant and abrasion-resistant material, for example, carbon-graphite antifriction materials, such as Himanit-T, NIGRAN, NIGRAN-V.

Cases 7 and 8 form the reactor space at the ends. Each of the housings is mounted on its fixed frame (frames not shown) with the possibility of rotation and axial movement to ensure docking with the end of the shell and to set a predetermined gap between the end of the shell and the inner surface of the shell. Such installation is not difficult for specialists.

The design of the reactor allows for convenient supply of raw materials, processing aids and coolant to the reactor, as well as convenient removal of pyrochol and steam and gas from the reactor cavity due to the fact that the hulls are stationary and therefore easily and reliably interface with devices for loading raw materials and dispensing the finished product.

The installation of the shell obliquely and with the possibility of rotation at an adjustable speed relative to the shells ensures that raw materials, coolant and pyrolysis products are advanced in the shell cavity at the optimum speed for this type of raw material by controlling the speed of rotation of the shell, as well as its high-quality mixing and contact with the coolant with a high degree heat transfer.

Thus, the design of the reactor allows us to ensure high productivity of the pyrolysis process with a high degree of processing of raw materials, high adaptability of the pyrolysis process to a wide range of raw materials to obtain high quality pyrolysis products. In addition, the design of the reactor is very technological, as it provides a simple and convenient maintenance, installation and dismantling of structural elements in its cavity due to the possibility of removal of the shells from the ends of the shell.

The reactor is equipped with a device for loading raw materials and technological additives into its cavity, including a hopper 10 and a conveyor 11 (for example, a screw), introduced into the shell cavity through the upper housing 7.

The gas outlet of the gas generator 1 is connected to the cavity of the pyrolysis reactor by a pipeline (not indicated by a position) for supplying a coolant into its cavity. The pipeline is introduced into the reactor cavity through the upper body 7.

On the surfaces of the housings 7 and 8, temperature sensors 12 and pressure 13 of the medium inside the reactor, consisting of gas and solid particles of raw materials, are installed.

A start burner 14 can be mounted on the upper case 7 for heating the cavity of the shell 4 before starting the reactor.

The mechanism 15 of rotation of the shell 4 is mounted on one of the supports 6. This mechanism is made in a known manner, for example, in the form of an engine with an adjustable speed of rotation of its output shaft and a gear or friction gear.

The inner surface of the shell 4 may have a lining made of abrasion-resistant and heat-resistant material, for example, refractory, lightweight concrete ZhSB-1000 or ZhSB-1200 coated with a refractory oxide-ceramic KR-1 or M-5.

On the inner surface of the shell along its length (longitudinally) are attached, preferably at an equal distance from each other around the circumference, agitators 16 of the raw material entering the reactor cavity. The number of agitators depends on the diameter of the shell and is, as a rule, from 10 to 20. Each agitator is made in the form of a plate with a height h. Tedders made in the form of plates can be solid or prefabricated, joined at the ends of several parts. On half of the agitators, on their periphery there may be shelves located at an angle of 90 ° to the plate. When mounting agitators, they are installed so that agitators with shelves and without shelves alternate with each other. The width l of the shelves is selected from the condition l = (0.5-0.6) h. As experience has shown, it is precisely such a size ratio of agitators that allows for the most qualitative mixing of raw materials during rotation of the shell.

After installing the agitators in the cavity of the shell, its internal passage diameter is d2. It was established that the most optimal value of d2 should correspond to the value of d2 = (0.65-0.75) d1. With this ratio, the most qualitative distribution of raw materials occurs over the cross-section of the shell of the pyrolysis reactor during its rotation and provides the most complete heat transfer between the raw material and the coolant.

A gas outlet (not indicated by a position) of the reactor is provided on the upper part of the lower housing 8. A solid outlet is connected to the gas outlet of the device 17 for cleaning the vapor-phase gases removed from the reactor cavity. The device 17 can be made in the form of a standard cyclone.

In the lower part of the casing 8 there is a channel (not indicated by the position) for issuing pyrocoal from the cavity of the reactor, to which a discharge device 18 (for example, a conveyor) of pyrocoal is connected, by means of which pyrocoal enters the storage hopper 19. It is advisable that the discharge device 18 be connected the output of the solid phase from the device 17.

The gas output of the purification device 17 is connected to the input of the heat exchanger 3, the output of which is connected to the input of the apparatus 21 for separating gas and vapor into liquid and gas phases. The movement of steam and gas through the device 17, the heat exchanger 3, the apparatus 21 and the delivery of gas to the consumer is ensured by the draft created by the smoke exhauster 20 connected to the gas outlet of the apparatus 21. The gas and steam transported through the heat exchanger are a heat carrier for the air supplied to the gas generator 1. At the bottom of the apparatus 21 there is an outlet (not indicated by position) for dispensing liquid fuel to a consumer.

Known tube or spiral heat exchangers can be used as heat exchanger 3, separators, distillation columns and other devices widely known in the industry can be used as steam and gas separation apparatus 21. The use of a particular device is dictated by the types of processed raw materials and the technological features of its processing, or by the need to obtain a specific range of products. In any case, the well-known equipment that is not subject to patent protection is used to separate the combined cycle gases into components.

Creation and maintenance of optimal parameters of the pyrolysis process is provided by the automatic control system 22, which is part of the installation, which includes temperature, pressure sensors, measuring the amount of supplied raw materials, air, coolant, unloading of pyrocoal and combined-cycle gases, as well as frequency converters of the rotation speed of the shafts of the rotation mechanism engines shells, engines for loading raw materials into a gas generator and a reactor, engines for unloading pyrochol from a reactor, blower engines and a smoke exhaust. The control system also includes programmable controllers, which, using the indicators of the sensors, support, due to the control of the frequency converters, the optimal plant settings specified by the program.

Units and assemblies of the installation, the design of which is not disclosed in the description, are standard and perform the inherent functions during the operation of the installation.

Relations in this application should be understood as means (pipelines, conveyors, etc.) by which, during the operation of the installation, transportation of raw materials, processing aids and working agents is carried out.

In the installation variant, the only difference is that the gas generator 1 with the feed and ash unloading devices is excluded from the aggregates, and the pipeline, from the blower 2, passed through the heat exchanger 3, is connected to the gas inlet of the reactor vessel 7 instead of the gas generator.

Installation works as follows.

Initially, a gaseous coolant is obtained, for which raw materials are loaded into a heated gas generator 1 and air is pumped into the gas generator 2 through a pipe through a heat exchanger 3. As a rule, the gas generator 1 runs on the same raw material as the reactor.

In parallel with the preparation for operation of the gas generator 1, include a start-up burner 14, which provides heating of the reactor, the cleaning device 17 and the heat exchanger 3. After reaching their design temperature, the start-up burner 14 is turned off.

Next, a gas generator 1 is turned on, which pumps the resulting coolant into the reactor cavity.

A mechanism 15 is turned on, which drives the shell 4 into rotation at a predetermined speed. Raw materials and processing aids are loaded into the pyrolysis reactor from the hopper 10 through the conveyor 11. As technological additives, catalysts are most often used, as well as substances that prevent harmful emissions, for example, lime, dolomite, aluminosilicates.

The feed loaded into the reactor enters the lower part of the rotating shell 4 near the housing 7, where it is picked up by the agitators 16 and rises on them up to the point where the angle of inclination of the agitator reaches a value at which the raw material is poured down and at the same time due to the inclination of the rotating shell 4 to the horizontal plane of the raw material moves during the fall by a certain amount along the drum of the shell in the direction of the housing 8.

Thus, the raw material inside the pyrolysis drum is distributed over the volume of the shell and gradually moves from the housing 7 to the housing 8, while under the influence of the temperature of the coolant, the raw materials are degraded into pyrocoal and vapor-gases.

Actually, the pyrolysis process itself is widely known, it is described in detail in the technical literature and does not need additional explanations.

Due to the fact that the agitators 16 can be made both with shelves and without shelves and installed alternately in the cavity of the shell, the starting points of the pouring from the tedding of raw materials in the shell during its rotation will be separate over the cross section of the shell and, therefore, uniform the distribution of raw materials over the cross section of the shell and its uniform mixing with hot coolant while moving the raw materials from the housing 7 to the housing 8, which ensures a high speed and degree of degradation of the raw materials and high quality of pyrolysis products.

Constant mixing of raw materials in the reactor due to the use of agitators and rotation of the shell, with the contact of the hot coolant with a large surface of the particles of raw materials at the optimum amount of raw materials, the contact time of the raw materials and coolant and the ambient temperature in the reactor, which are supported by the automatic control system, provide pyrolysis of raw materials with high performance and obtaining high-quality pyrolysis products - pyrocholum, liquid fraction, non-condensable gas.

The resulting combined-cycle gas from the reactor through the outlet in the upper part of the housing 8 enters the purification device 17. The solid particles extracted from the combined gas in the purification device 17 are fed to the discharge device 18 and then to the storage hopper 19 together with pyrochrome.

The vapor-gas cleaned from the solid phase due to the operation of the smoke exhauster 20 is supplied from the cleaning device 17 through the heat exchanger 3 (where part of the heat is supplied to the air supplied through the pipeline to the gas generator) to their separation apparatus 21, where they are separated into components, depending on the type of apparatus used 21.

So, for example, when using a distillation column 21 as an apparatus, non-condensable gas is obtained from combined-cycle gas, which can be used to generate heat and electricity, a light fraction of liquid fuel similar in properties to diesel fuel, which can be used for transport engines or turbines, a heavier fraction of liquid fuel, similar in properties to heating oil, which can be used in boiler furnaces. The resulting liquid fraction is discharged through the lower part of the apparatus 21.

The pyrocarbon obtained in the reactor is discharged through the channel in the lower part of the housing 8 by means of the device 18. Pyrocoal can be used as a sorbent, as a reducing agent, as smokeless fuel, as a raw material, the liquid fraction can be used as heating oil, as a raw material for the chemical industry, non-condensable gas can be used as raw materials, as fuel for heat and electricity, as fuel for firing building materials.

The difference in the operation of the installation according to the variant of its execution is that heated air is used as the heat carrier, pumped into the reactor cavity by the blower 2. The required amount of the coolant supplied by the blower is controlled by changing the capacity of the blower 2.

The design of the installation provides convenient loading of raw materials and coolant into the reactor, promotion with constant stirring of raw materials in the reactor, as well as convenient evacuation of pyrolysis products from the reactor. The design of the installation provides the ability to control in a wide range of such basic parameters of pyrolysis as: temperature in the reactor, by controlling the temperature of the coolant; the residence time of the raw materials in the reactor, due to changes in the angular velocity of rotation of the shell; highly efficient mixing and heat transfer between the raw material and the coolant, due to the rotation of the shell and the presence of agitators inside it.

The design of the installation option provides a large amount of highly purified combustible gas and a small amount of liquid fraction, which is caused by the prevailing oxidation reaction of raw materials in the reactor when heated air, which contains more than 20 masses, is supplied as a heat carrier. % of such a powerful oxidizing agent as oxygen. The advantage of the installation option is that it does not require deep purification of the liquid fraction obtained during the processing of raw materials, which is supplied together with the raw materials to the reactor, as well as reducing the cost of operations with the obtained product - gas, which can be transferred directly to the consumer. It is also very important that during the operation of such an installation, environmental pollution is reduced by the dust fraction of pyrochl and vapor from the liquid fraction.

The choice of a specific installation is determined depending on the requirements of consumers according to the nomenclature, quantity and quality of products obtained from processing of raw materials and the raw materials used.

If it is necessary to obtain pyrocholum, liquid fraction, combustible gas and ash, the first installation option is usually used. If it is necessary to obtain combustible gas, as a rule, the second installation option is used.

Installations can be effectively used for processing the following types of raw materials: municipal solid waste; municipal and agricultural waste (sludge from sewage treatment, manure, litter, vegetable waste); coal, oil refining, wood processing industries waste, brown coal, lignite, etc.
