Description

Horizontal garbage disposal furnace and garbage disposal system

Technical Field

The utility model relates to a rubbish field especially relates to a horizontal refuse treatment stove and refuse treatment system.

Background

In the existing garbage treatment mode, a scheme named as a biomass gasification technology is adopted, and biomass (organic matter containing C, H, O) is cracked under the environment of oxygen inhibition and high temperature (450-800 ℃) to obtain biomass fuel gas (CH4, H2 and CO) and biochar. The biomass gasification technology is realized by an updraft gasifier, a downdraft gasifier and a fluidized bed gasifier.

The updraft gasification furnace means that the moving directions of air and materials in the furnace are reverse: air is blown in from the lower part of the gasification furnace, and is changed into fuel gas after reacting with the materials, and the fuel gas is pumped out from the upper part of the gasification furnace. The updraft gasifier has the advantages of high reaction efficiency and the disadvantages of large tar content in fuel gas and low charcoal quality.

The downdraft gasification furnace means that the moving directions of air and materials in the furnace are the same direction: air enters from the upper part or the waist part of the gasification furnace, reacts with the materials and then is changed into fuel gas to be pumped out from the lower part of the gasification furnace. The downdraft gasifier has the advantages of low tar content of biomass gas, high quality of biochar and relatively low reaction efficiency.

The fluidized bed gasification furnace is characterized in that air is blown into the gasification furnace from the lower part of a material, so that the material is in a fluid state in the furnace. The fluidized bed gasification furnace has the advantages of high reaction efficiency and small tar content of biomass gas, and has the defect of high requirement on the homogenization degree of materials.

In order to overcome the defects of the gasification furnace, the prior art provides a horizontal gasification furnace: the material is transported by the auger and moves along the axial direction of the horizontal gasifier, and air is introduced from the bottom of the horizontal gasifier. The method well overcomes the dependence on the homogenization degree of the material, improves the reaction efficiency and improves the quality of the biochar. However, the horizontal gasification furnace proposed by the prior art still has many disadvantages:

1. the bottom of the air cabin is blown with air, which is not beneficial to accurately controlling reaction conditions along the axial direction of the gasification furnace, and the reaction front end of the furnace body is a drying area used for separating moisture in materials; the back end is a reaction area used for cracking the materials at high temperature to become biomass gas and biochar. In the existing scheme, only one gas bin is provided for distributing air to the whole furnace body, and the reaction cannot be accurately controlled;

2. the existing furnace body main shaft is not cooled or adopts a water cooling mode. The main shaft of the furnace body can deform at high temperature if not cooled; a large amount of heat can be taken away by water cooling, so that the reaction efficiency of the horizontal furnace is reduced, and the taken heat cannot be recycled;

3. the main shaft of the furnace body is not provided with a stir-frying device, and the blade of the main shaft is not provided with a hole. Thus, the heat conduction is not facilitated, and the reaction efficiency is low;

4. in the prior art, an explosion-proof port is not designed, and if explosion happens, a pressure relief port is not arranged, so that the mechanical structure is damaged, and even potential safety hazards are caused;

5. the amount of the generated fuel gas tar is large.

Therefore, there is a need for a new horizontal garbage disposal furnace that overcomes the above problems.

At this top department, be equipped with above-mentioned first fan 7, first fan 7 starts the back, will absorb the outside air to squeeze into air supply channel with the outside air from the air intake, because air supply channel sets up along the axial of air-cooled auger 4 with the cold air pipe is the same, consequently, the length of whole air-cooled auger 4 will almost be passed to the outside air, and after the outside air runs through the cold air pipe, will carry to the inside of air-cooled auger 4.

Air-cooled channel

The hollowed inner cavity of the air-cooled auger 4 is used as an air-cooled channel except the cold air pipe, the air-cooled channel is communicated with the air outlet end of the air supply channel, the other side end of the air-cooled auger is communicated with the outside through an air outlet after receiving outside air, and preferably, the air outlet is arranged at the top end of the air-cooled auger 4 and close to the air inlet of the cold air pipe. And the position of the air cooling channel close to the bottom end is communicated with the air bin 6, or when the air outlet of the air cooling channel is arranged at the top end, the air bin 6 is close to the air inlet position of the cold air pipe.

Through the configuration, after entering the air supply channel, the external air is transmitted from top to bottom along the axial direction of the air-cooled packing auger 4 and then enters the air-cooled channel, and then is transmitted from bottom to top along the air-cooled packing auger 4, and the contact time between the external air and the air-cooled packing auger 4 is increased through the curved transmission path, so that the heat received by the air-cooled packing auger 4 in the horizontal furnace body 2 is taken away in an air-cooled manner, and the effect of cooling the air-cooled packing auger 4 is achieved. In addition, hot air after heat exchange enters the air bin 6, oxygen serving as a gasification medium can be provided for the horizontal furnace body 2, and the heat of the gasification medium is the air after heat exchange, so that the heat can be directly used for heating garbage materials, and the supply amount of external heat energy is saved.

In a preferred embodiment, the bottom opening of the cold air pipe is communicated with the air cooling channel, and the top end of the cold air pipe can be welded or integrally formed at the top end of the air cooling auger 4 so as to fix the cold air pipe inside the air cooling auger 4, thereby forming a circulation path from the first fan 7, the air inlet, the air supply channel, the air cooling channel, the air outlet or the air bin 6. In addition, air-cooled auger 4 still including turning over the portion of stir-fry, turn over the portion of stir-fry and can be spiral shell area or steel sheet, and fixed mounting turns over the stir-fry about the rubbish material in the pitch of air-cooled auger 4, when air-cooled auger 4 carries the rubbish material for the air of blowing into inside can be with even and fully contact of rubbish material, accelerates gasification rate. Moreover, holes can be selectively formed on auger blades of the air-cooled auger, so that heat transfer is enhanced, and the gasification rate is accelerated.

In this embodiment, in order to realize the design of different air distribution amounts at different positions of the air-cooled auger 4, the air bin 6 is configured in a sectional design, and specifically, the air bin 6 includes a first air bin unit and at least one second air bin unit, wherein the first air bin unit is disposed at the ignition point and is communicated with the air-cooled channel, which is in a cavity form, air discharged from the air-cooled channel enters the first air bin unit, and since the air discharged from the air-cooled channel is hot air after cooling the air-cooled auger 4, heat contained in the air is discharged from the first air bin unit and is introduced into the horizontal furnace body 2 from the first air bin, so as to provide heat energy required by the reaction for the material at the front end of the horizontal furnace body 2. And the second air bin unit sets up in the position that first air bin unit more leaned on, and with the pattern of segment, arranges gradually to the top of horizontal furnace body 2, the one end of each second air bin unit and the inside intercommunication of horizontal furnace body 2, the supply-air outlet has been seted up to the other end, each supply-air outlet all can be equipped with a second fan 8, second fan 8 starts the back, sends into the second air bin unit with outside air from the supply-air outlet. Because the adjacent second air bin units are isolated from each other, the air distribution rate of each second air bin unit can be determined by the configuration of the air supply rate of the second fan 8, and when the air supply rates of different second fans 8 are inconsistent, the air distribution rates of different second air bin units to different positions in the horizontal furnace body 2 are inconsistent, so that different air quantities of different positions in the horizontal furnace body 2 are realized, and an operation user can adjust the air supply rate of the second fan 8 according to the air quantity demand of garbage materials in different states.

In another preferred or optional embodiment, an opening is formed in the outer wall of the horizontal furnace body 2 near the top end, an explosion-proof device 5 is covered on the opening, and the explosion-proof device 5 specifically includes:

-a catharsis port

The ventilation opening is communicated with the inside of the horizontal furnace body 2 and further communicated with the outside, so that fuel gas generated in the gasification process is discharged from the ventilation opening, and the excessive pressure in the horizontal furnace body 2 is prevented.

Explosion-proof cover

The explosion-proof cover is integrally covered on the vent hole, and two ends of the explosion-proof cover extend towards the direction close to the horizontal furnace body 2, so that after the gas is discharged from the vent hole, the gas is discharged along the gap between the lower edge of the explosion-proof cover and the side wall of the vent hole.

-explosion-proof enclosure

By adopting the water seal mode, when the air pressure in the horizontal furnace body 2 is too high, deflagration gas is discharged to the explosion-proof liquid position of the water seal from the air vent, and when fuel gas is too much and deflagration phenomenon is generated in the horizontal furnace body 2. The high-temperature gas pushes out the explosion-proof liquid. Because the explosion-proof cover is fixed on the explosion-proof fence through the steel bar, the explosion-proof cover can not be jacked open. The explosion-proof liquid has the function of sealing and overflows when the pressure is overlarge, so that high-temperature and high-pressure gas escapes. After the gas escapes, the explosion-proof liquid is automatically supplemented, and the sealing effect is achieved again.

Referring to fig. 3, in another preferred embodiment, in order to remove dust from the fuel gas, an air extractor 25 is disposed outside the air outlet to extract the fuel gas from the cold air duct; the upper part of the horizontal furnace body 2 is provided with a gas outlet, the gas outlet is connected with a first air seal valve 26, a first cyclone dust removal device 27, a second air seal valve 28 and a second cyclone dust removal device 29, the first cyclone dust removal device 27 and the second cyclone dust removal device 29 remove dust in gas, and the first air seal valve 26 and the second air seal valve 28 isolate the first cyclone dust removal device 27 and the second cyclone dust removal device 29 from the external space.

Referring to fig. 3, after the horizontal garbage disposal furnace is provided, it can be used in combination with another vertical garbage disposal furnace 12 to realize a two-stage garbage disposal system. The horizontal garbage furnace is provided with a discharge hole, the vertical garbage furnace 12 is provided with a feed hole, the discharge hole is connected with the feed hole through a connecting channel 11, the connecting channel 11 can be in a horseshoe shape, and the height of the discharge hole is higher than that of the feed hole, so that garbage materials discharged from the horizontal garbage furnace automatically drop into the vertical garbage furnace 12 along the connecting channel 11. The side wall lining of the connecting channel 11 is made of refractory castable, the periphery of the connecting channel is provided with a cooling layer, and after water is injected into the connecting channel, the connecting channel 11 can keep a stable state at a high temperature. In addition, the upper end of the connecting channel 11 is connected with the discharge port through a flange structure, and the lower end is also connected with the feed port through a flange structure. The flange structure is adopted, so that the assembly and the disassembly are convenient.

After entering the vertical waste treatment furnace 12 from the feed inlet, the waste material will settle, and therefore the vertical waste treatment furnace 12 will comprise the following components to further treat the waste material, in particular:

-a treatment section

The treatment part firstly receives the garbage materials, and the garbage materials are converted into carbon materials after being deposited at the treatment part.

-a distribution device 10

Part of the distributing device 10 is fixedly installed in the treating section and can rotate around a fixed axis, which may be along the axial direction of the vertical garbage treating furnace 12 or parallel to the axial direction of the vertical garbage treating furnace 12. When the processing portion receives the garbage materials and receives the increased garbage materials, the material level of the garbage materials gradually rises, and after the garbage materials are contacted with the material distribution device 10 along with the rising of the material level (the garbage materials enter the processing portion at an initial stage and are not contacted with the material distribution device 10), the rotation of the material distribution device 10 is hindered due to the existence of the garbage materials, so that the torque for maintaining the rotation of the material distribution device 10 is changed by the garbage materials, specifically, the torque needs to be increased, and the rotation of the material distribution device 10 at a set speed can be maintained. When the torque is rotated to be larger than a torque threshold value (the torque threshold value is preset in a controller connected with the distributing device 10), the distributing device 10 judges that the material level of the garbage materials is too high, the material quantity of the deposited garbage materials is enough, and the garbage materials can be carbonized, so that the distributing device 10 generates a carbon discharging instruction, and the carbonization process of the garbage materials in the vertical garbage treatment furnace 12 is activated by the processing part.

In this embodiment, the forming of the char command may be such that the torque is at least 5% greater than the torque threshold and the char command is formed for a certain time, such as 30 seconds, 60 seconds, etc., to ensure an accurate estimate of the stock level.

It can be understood that, when the processing portion processes the waste material so that the material level of the waste material is lowered, the waste material is no longer in contact with the material distribution device 10, so that the torque of the material distribution device 10 is restored to the initial value, and the material distribution device 10 may stop generating the carbon discharging instruction, or generate the stop instruction so as to stop the carbonization processing of the processing portion on the waste material.

Carbon storage section

The carbon storage part is arranged below the treatment part, and carbon materials formed after the treatment of the garbage materials by the treatment part are stored in the carbon storage part until being discharged out of the vertical garbage treatment furnace 12.

Carbon output device

The carbon discharging device is electrically connected with the distributing device 10 or a controller connected with the distributing device 10, is connected with the bottom of the carbon storage part, is started to receive the carbon material in the carbon storage part after receiving a carbon discharging instruction, and gradually discharges the carbon material out of the vertical garbage treating furnace 12. The carbon discharging device can be equipment with the water-cooling packing auger 20 and the first closed valve 21 in matched connection, and carbon materials fall to the water-cooling packing auger 20 and are conveyed to the first closed valve 21 by the rotation of the water-cooling packing auger 20 to be discharged. The design of the first closed valve 21 can ensure the discharging and isolate the air.

Through distributing device 10's design, avoided using the design that uses infrared inductor response material level among the prior art, if use infrared inductor, because high temperature, high dust environment in the processing portion, infrared inductor will disturb too big in this environment, can't truly reflect the material level condition. Therefore, after the material distribution device 10 is adopted, the material level of the garbage material can be judged more accurately.

Preferably, the material distribution device 10 specifically includes:

-a distribution bar

The distributing rod is of a strip-shaped structure, the first end of the distributing rod extends into the processing part, and the second end of the distributing rod extends outwards to form a fixed shaft. It can be understood that the length of the distribution rod will determine the length of the distribution rod extending into the interior of the treatment section, and the length of the extending portion further determines the torque of the material level, that is, the deeper the depth of the first end of the distribution rod in the waste material, the greater the torque lifted by the waste material. Therefore, the operating user can adjust the extending depth of the first end according to the requirements of working conditions.

-an electric machine

The second end department of cloth pole is connected with the motor, and through the setting of motor, when the motor is rotatory, steerable cloth pole is rotatory around its fixed axle.

-a scraper
