[0002] Waste incineration power generation is the work of introducing, digesting, absorbing and re-innovating waste incineration plants and waste incineration equipment. Dioxins in the flue gas of municipal solid waste incineration have been a matter of common concern in various countries in recent years. Dioxin-like highly toxic substances cause great harm to the environment. Effectively controlling the generation and diffusion of dioxin-like substances is directly related to the popularization and application of waste incineration and waste power generation technologies.

[0003] As disclosed in a vehicle-mounted solid waste treatment equipment with the authorization announcement number of CN117029008A, it has a trailer board, a waste recycling bin is installed on the trailer board, a sorting machine is connected to the waste recycling bin, the sorting machine is connected to an incinerator through a screw feeder, a waste heat boiler is connected to the incinerator through a smoke outlet pipe, a flue gas purifier and a generator are connected to the waste heat boiler, and a bag filter is connected to the flue gas purifier. After adopting the above technical scheme, the beneficial effect of the utility model is: through the setting of the driving structure and the air intake structure, when waste is incinerated, the intake pipe can drive a plurality of outlet pipes to swing, and the outlet pipes can drive the stirring teeth to swing, so that the waste burning in the incinerator can be scattered and sufficient air supply can be ensured, thereby effectively ensuring the full combustion of the waste.

[0004] Although the above patent can scatter the waste burning in the incinerator and ensure sufficient air supply, thereby effectively ensuring the full combustion of the waste, there is no waste heat recovery mechanism in its structure. Therefore, the gas generated after the incinerator burns has high heat, and these heats cannot be effectively utilized, resulting in a certain waste of resources. Content of the Utility Model

[0005] The purpose of the utility model is to provide a vehicle-mounted integrated machine for biomass gasification power generation to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical scheme:

[0007] A vehicle-mounted integrated machine for biomass gasification power generation, comprising

[0008] A vehicle board;

[0009] A biomass gasification furnace, a centrifugal separator, a tar condenser, a flue gas treatment box and an internal combustion engine are sequentially arranged on the upper end of the vehicle board from left to right;

[0010] The biomass gasifier is connected to the centrifugal separator through a first pipeline, the centrifugal separator is connected to the tar condenser through a second pipeline, the tar condenser is connected to the flue gas treatment tank through a third pipeline, and the flue gas treatment tank is connected to the internal combustion engine through a fourth pipeline;

[0011] A waste heat recovery mechanism is provided between the tar condenser and the flue gas treatment tank and the biomass gasifier.

[0012] Preferably, the waste heat recovery mechanism includes an air delivery pipe, the air delivery pipe is arranged between the tops of the tar condenser and the flue gas treatment tank, and a delivery pump is installed in the middle of the air delivery pipe;

[0013] Preferably, the waste heat recovery mechanism further includes a first inner pipe and a second inner pipe, the first inner pipe is arranged inside the tar condenser, the top end of the first inner pipe is connected to the left end of the air delivery pipe, the second inner pipe is arranged inside the flue gas treatment tank, and one end of the second inner pipe is connected to the right end of the air delivery pipe;

[0014] Preferably, the waste heat recovery mechanism further includes a recovery pipe, one end of the recovery pipe is connected to the oxygen inlet of the biomass gasifier, and the other end of the recovery pipe is connected to the ends of the first inner pipe and the second inner pipe away from the air delivery pipe;

[0015] Preferably, a compression pump is installed in the middle of the first pipeline between the bottom ends of the biomass gasifier and the centrifugal separator;

[0016] Preferably, a screw conveyor is fixedly installed on the left side of the vehicle board close to the biomass gasifier through a bracket, and the discharge end of the screw conveyor is connected to the feed end of the biomass gasifier.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] For this biomass gasification power generation vehicle-mounted integrated machine, when the biomass is burned by the biomass gasifier, the delivery pump is started, and the delivery pump pumps external air into the air delivery pipes at both ends. The air delivery pipes at both ends respectively absorb the heat of the high-temperature gas entering the tar condenser and the flue gas treatment tank, and then enter the recovery pipe, and are sent into the biomass gasifier through the recovery pipe. By supplying oxygen in the biomass gasifier, the combustion efficiency and reaction speed can be improved, and the waste heat of the air inhaled from the outside can be treated.

[0019] For this biomass gasification power generation vehicle-mounted integrated machine, when the transfer pump is started, external low-temperature air enters the tar condenser from the gas pipeline at the left end, and then flows along the first inner pipe. At this time, the high-temperature air entering the interior of the tar condenser from the second pipeline has its heat absorbed by the low-temperature air flowing in the first inner pipe, thereby reducing the temperature of the gas entering the interior of the tar condenser. Since the temperature of the gas entering the interior of the tar condenser decreases, the grease generated during combustion can condense into a liquid. In this way, while recovering and utilizing the gas heat and supplying it for combustion in the biomass gasifier, it can also assist the tar condenser in treating the grease in the gas, thereby expanding the application range and efficiency of the waste heat recovery mechanism.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1-4 shown, a technical solution provided by the present invention:

[0027] A vehicle-mounted integrated machine for biomass gasification power generation, comprising a vehicle board 1; a biomass gasification furnace 2, a centrifugal separator 3, a tar condenser 4, a flue gas treatment box 5 and an internal combustion engine 6 are sequentially arranged on the upper end of the vehicle board 1 from left to right; the biomass gasification furnace 2 is communicated with the centrifugal separator 3 through a first pipeline 7, the centrifugal separator 3 is communicated with the tar condenser 4 through a second pipeline 8, the tar condenser 4 is communicated with the flue gas treatment box 5 through a third pipeline 9, and the flue gas treatment box 5 is communicated with the internal combustion engine 6 through a fourth pipeline 10; a waste heat recovery mechanism is arranged between the tar condenser 4 and the flue gas treatment box 5 and the biomass gasification furnace 2; the waste heat recovery mechanism includes an air delivery pipe 11, the air delivery pipe 11 is arranged between the tops of the tar condenser 4 and the flue gas treatment box 5, and a delivery pump 12 is installed in the middle of the air delivery pipe 11; the waste heat recovery mechanism further includes a first inner pipe 13 and a second inner pipe 14, the first inner pipe 13 is arranged inside the tar condenser 4, the top end of the first inner pipe 13 is communicated with the left end of the air delivery pipe 11, the second inner pipe 14 is arranged inside the flue gas treatment box 5, and one end of the second inner pipe 14 is communicated with the right end of the air delivery pipe 11; the waste heat recovery mechanism further includes a recovery pipe 15, one end of the recovery pipe 15 is communicated with the oxygen inlet of the biomass gasification furnace 2, and the other end of the recovery pipe 15 is communicated with the ends of the first inner pipe 13 and the second inner pipe 14 far away from the air delivery pipe 11; a compression pump 16 is installed in the middle of the first pipeline 7 between the bottom ends of the biomass gasification furnace 2 and the centrifugal separator 3; a screw conveyor 17 is fixedly installed on the left side of the vehicle board 1 close to the biomass gasification furnace 2 through a bracket, and the discharge end of the screw conveyor 17 is communicated with the feed end of the biomass gasification furnace 2;

[0028] In this embodiment, when the biomass is burned by the biomass gasification furnace 2, the delivery pump 12 is started, and the delivery pump 12 pumps external air into the air delivery pipes 11 at both ends. The air delivery pipes 11 at both ends respectively absorb the heat of the high-temperature gas entering the tar condenser 4 and the flue gas treatment box 5, and then enter the recovery pipe 15, and are sent into the biomass gasification furnace 2 through the recovery pipe 15. By supplying oxygen into the biomass gasification furnace 2, the combustion efficiency and reaction speed can be improved, and the waste heat of the air inhaled from the outside can be treated.

[0029] Furthermore, when the delivery pump 12 is started, the external low-temperature air enters the tar condenser 4 from the air delivery pipe 11 at the left end, and then flows along the first inner pipe 13. At this time, the high-temperature air entering the tar condenser 4 from the second pipeline 8 is absorbed by the low-temperature air flowing in the first inner pipe 13, thereby reducing the temperature of the gas entering the tar condenser 4. Since the temperature of the gas entering the tar condenser 4 is reduced, the grease generated during combustion can be condensed into a liquid. In this way, while recovering and utilizing the gas heat and supplying it to the biomass gasification furnace 2 for combustion, the grease in the gas can be assisted to be treated by the tar condenser 4, which can improve the application range and effect of the waste heat recovery mechanism.

[0030] Working principle: First, biomass raw materials such as garbage and wood chips are input into the biomass gasifier 2 through the screw conveyor 17. The biomass materials in the biomass gasifier 2 pass through the preheating area and enter the gasification reaction area. At a high temperature of 700°C to 1000°C, oxygen in the air reacts with the biomass materials by combustion, generating gases such as carbon monoxide, carbon dioxide, and water vapor. The synthesis gas is pumped to the centrifugal separator 3 by the compression pump 16. The gas is separated and treated by the centrifugal separator 3 to remove the solid particles and dust therein. Then, the gas enters the tar condenser 4 through the second pipeline 8. The tar condenser 4 removes or reduces the tar in the gas. Finally, the gas enters the flue gas treatment box 5 through the third pipeline 9. Limestone slurry is provided in the flue gas treatment box 5, and the sulfide is absorbed from the flue gas by the limestone slurry. The synthesized gas after the cleaning treatment enters the internal combustion engine 6 through the fourth pipeline 10. The internal combustion engine 6 generates high-temperature and high-pressure working gas by burning the synthesis gas to drive the generator to generate electricity.
