A flue gas emission device for a high-temperature gasification cogeneration furnace

Abstract

This utility model discloses a flue gas emission device for a high-temperature gasification cogeneration furnace, including a main gas pipe and a treatment chamber located on the left side of the main gas pipe. An inlet pipe is located on the right side of the treatment chamber, with its outer periphery fitting against the inner wall of the left end of the main gas pipe. An outlet pipe is located on the left side of the treatment chamber, and a sealing ring is fixedly installed on the right side of the treatment chamber. In this design, when the gas enters the treatment chamber through the inlet pipe, extraction pumps located on both sides of the separator extract the desulfurizing agent and denitrifying agent stored in the separator. Simultaneously, a motor located on the left side of the second liquid-passing pipe drives the second liquid-passing pipe, along with the first liquid-passing pipe, to rotate, causing the nozzle to reciprocate. This ensures that the treatment agent comes into full contact with the gas, achieving immediate gas treatment to meet subsequent usage requirements and improving the device's practicality.

Description

Technical Field

[0001] This utility model relates to the field of biomass gasification equipment technology, and more specifically, to a flue gas emission device for a high-temperature gasification cogeneration furnace. Background Technology

[0002] Biomass gasification is a clean energy process that uses agricultural and forestry waste biomass raw materials such as crop straw, agricultural waste, sawdust, and wood shavings to process into biomass pellet fuel. Biomass pellet fuel is pyrolyzed and gasified into combustible gas at high temperatures. Traditional gasification devices use a feeder to feed the raw materials into the biomass gasification furnace to produce gas through pyrolysis and reduction reactions. Only one biomass gasification furnace is used to produce gas, resulting in low production efficiency.

[0003] To address the aforementioned issues, patent document publication number CN220376618U discloses a downdraft high-temperature gasifier, comprising a fluidized bed conveying mechanism, a screw conveyor feeding mechanism, a fluidized bed gasifier body, a carbonization furnace feeding mechanism, a carbonization furnace body, and a gas main pipe.

[0004] However, it still has some drawbacks in actual use. For example, the gas produced in the above device eventually flows into the gas main. If the gas is used for combustion heating, a flue gas treatment system is required. However, the structure of the gas main is limited and it cannot treat the discharged gas, which reduces the practicality of the device to some extent. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a flue gas emission device for a high-temperature gasification cogeneration furnace, so as to solve the problem that the prior art cannot process the generated gas, thus delaying its subsequent use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flue gas emission device for a high-temperature gasification co-production furnace, including a main gas pipe, and the flue gas emission device for the high-temperature gasification co-production furnace further includes...

[0008] The installation compartment is fixedly installed on the top of the processing chamber, and the bottom of the installation compartment is connected to the top of the processing chamber.

[0009] The separation tank is fixedly installed on the top surface of the installation chamber. The left and right sides of the separation tank are respectively provided with extraction pumps. The ports of the extraction pumps are fixedly connected to connecting pipes, and the end of the connecting pipes relative to the extraction pumps is fixedly connected to a connecting end.

[0010] Liquid passage pipe one and liquid passage pipe two are rotatably installed inside the left and right sides of the installation chamber, respectively. The right end of liquid passage pipe one is fixedly connected to the left end of liquid passage pipe two. The top of liquid passage pipe one and liquid passage pipe two are respectively connected to the bottom ends of two connecting ends.

[0011] It also includes a support ring and a fixing column. The inner ring of the support ring is rotatably connected to the surface of the two sides of the liquid passage pipe. The fixing column is disposed on both sides of the surface of the support ring, and one end of the fixing column relative to the support ring is fixedly connected to the inner wall of the installation chamber.

[0012] It also includes a motor, which is located on the left side of the processing chamber, and the drive shaft of the motor is fixedly connected to the left end of the liquid passage pipe 2.

[0013] It also includes a drain pipe and an electrically controlled valve. The top end of the drain pipe is fixedly connected to the bottom of the processing chamber, and the electrically controlled valve is located outside the drain pipe.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] In the above scheme, when the gas enters the treatment chamber through the inlet pipe, the desulfurizing agent and denitrifying agent stored in the separation tank are extracted by the extraction pumps set on both sides of the separation tank, and the treatment agent is sent into the liquid passage pipe one and liquid passage pipe two through the connecting pipes. The treatment agent is sprayed onto the gas through the nozzles set at the bottom of the liquid passage pipe one and liquid passage pipe two. At the same time, the motor set on the left side of the liquid passage pipe two drives the liquid passage pipe two and the liquid passage pipe one to rotate, so that the nozzle can rotate back and forth, thereby allowing the treatment agent to fully contact the gas, thus realizing the immediate treatment of the gas, making the gas meet the subsequent use requirements, and thus improving the practicality of the device.

[0016] The used desulfurizing agent accumulated in the treatment chamber can be discharged outward through the drain pipe installed at the bottom of the treatment chamber. By connecting the drain pipe to the corresponding equipment, the used desulfurizing agent and denitrifying agent can be directly treated, avoiding direct discharge that could impact the environment. Furthermore, the drain pipe can be sealed off by an electrically controlled valve to prevent accidental leakage. Attached Figure Description
