Description

Technical Field

[0001] This utility model relates to the field of recycling device technology, and in particular to a waste gas recycling device for a coal gas generator. Background Technology

[0002] The bell valve is a safety venting valve installed on the outlet pipeline of a gasifier. It automatically releases pressure when the pipeline is overpressurized. It can also be manually opened during gasifier commissioning, shutdown for maintenance, or malfunction to vent substandard gas from the furnace. Its function in the gasifier system is indispensable. Current technology involves a vent pipe at the outlet of each bell valve to discharge waste gas into the atmosphere, but this discharge exposes enterprises to various environmental problems.

[0003] The producer gasification method is a continuous gas production process, powered by a continuously operating air blower. Air is drawn in from the atmosphere by the blower, serving as one of the gasification feedstocks. It is then sent through a duct into the gasifier's bottom ventilation box, and subsequently enters the gasifier to react with coal to produce gas. This invention's waste gas recovery approach involves sending waste gas through a pipeline to the air blower's inlet. After being drawn in by the blower, it is carried into the gasifier along with the air through the duct. Directly connecting the waste gas pipeline to the blower's inlet duct would lead to the following problems: dust, tar, and water vapor contained in the waste gas would directly enter the ventilation system, damaging equipment and pipelines. Complete discharge of waste gas into the duct might result in excessively high local concentrations of combustible gases, posing an explosion hazard during transport. Furthermore, waste gas entering the duct might create air resistance, obstructing air intake and causing insufficient airflow, thus affecting gas production. Utility Model Content

[0004] In view of this, in order to solve the above problems, the purpose of this utility model is to provide a tank, a baffle, a drain pipe, and a valve;

[0005] A drain outlet is provided at the lower end of the tank, and the upper end of the drain pipe is installed inside the drain outlet;

[0006] The valve is installed on the sewage pipe, and the valve can open or close the sewage pipe.

[0007] The baffle is installed on the inner wall of the tank. The outer wall of the tank has an exhaust gas inlet, an air inlet and an air outlet. The exhaust gas inlet is positioned facing one surface of the baffle. The exhaust gas inlet, the air inlet and the air outlet are arranged sequentially from bottom to top. The air inlet is located on one side of the outer wall of the tank, and the air outlet is located on the other side of the outer wall of the tank.

[0008] In the aforementioned gas generator exhaust gas recovery device, the inner wall of the lower end of the tank is arc-shaped.

[0009] In the aforementioned gas generator exhaust gas recovery device, the baffle is arranged in an arc shape along the vertical direction.

[0010] In the above-mentioned gas generator exhaust gas recovery device, the upper surface of the baffle is provided with a smooth coating.

[0011] In the aforementioned gas generator exhaust gas recovery device, the inner diameter of the air inlet is larger than the inner diameter of the air outlet, and the inner diameter of the air outlet is larger than the inner diameter of the exhaust gas inlet.

[0012] The positive effects of the above technical solution compared with the existing technology are:

[0013] By applying this utility model, a gas generator exhaust gas recovery device is provided. The exhaust gas enters the tank through the exhaust gas inlet. Impurities in the exhaust gas are blocked by the baffle and fall to the bottom of the tank. At the same time, air is introduced through the air inlet, so that the air combines with the exhaust gas, reducing the concentration of the exhaust gas. Then it is discharged from the air outlet, which is safer. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0017] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0018] like Figure 1 As shown, a preferred embodiment of a gasifier exhaust gas recovery device is illustrated, comprising: a tank 1, a baffle 2, a drain pipe 3, and a valve 4.

[0019] A drain outlet is provided at the lower end of the tank body 1, and the upper end of the drain pipe 3 is installed inside the drain outlet; a valve 4 is installed on the drain pipe 3, and the valve 4 can open or close the drain pipe; a baffle 2 is installed on the inner wall of the tank body 1, and an exhaust gas inlet 5, an air inlet 6 and an air outlet 7 are provided on the outer wall of the tank body 1. The exhaust gas inlet 5 is set facing one surface of the baffle 2, and the exhaust gas inlet 5, air inlet 6 and air outlet 7 are arranged sequentially from bottom to top. The air inlet 6 is opened on one side of the outer wall of the tank body 1, and the air outlet 7 is opened on the other side of the outer wall of the tank body 1.

[0020] In actual use, the tank 1 of this application is a vertical structure, and the air inlet 6 and the exhaust gas inlet 5 are at a certain distance on the vertical tank 1.

[0021] The exhaust gas enters the tank through the exhaust gas inlet 5. Since the exhaust gas inlet 5 is directly opposite the baffle 2, the particulate impurities in the exhaust gas are blocked by the baffle 2 and fall to the bottom of the tank 1. The impurities are then discharged through the drain outlet and drain pipe 3. The exhaust gas after being blocked is then mixed with the air entering through the air inlet 6, thereby reducing the concentration of the exhaust gas. The exhaust gas after concentration treatment is then discharged through the air outlet 7, thus making the treatment of exhaust gas safer.

[0022] Based on the above, this utility model also has the following embodiments:

[0023] Furthermore, in a gasifier exhaust gas recovery device, the inner wall of the lower end of the tank 1 is arc-shaped. Furthermore, the arc-shaped inner wall of the lower end of the tank 1 makes it easier for impurities to accumulate at the bottom of the tank 1, thus facilitating their discharge.

[0024] Furthermore, in a gasifier exhaust gas recovery device, the baffle 2 has an arc-shaped cross-section along the vertical direction. This arc-shaped cross-section of the baffle 2 increases the shielding area and improves the shielding effect.

[0025] Furthermore, in a gasifier exhaust gas recovery device, the upper surface of the baffle 2 is provided with a smooth coating. Further, the smooth coating on the upper surface of the baffle 2 prevents impurities in the exhaust gas from accumulating on the upper surface of the baffle 2.

[0026] Furthermore, in a gasifier exhaust gas recovery device, the inner diameter of air inlet 6 is larger than the inner diameter of air outlet 7, and the inner diameter of air outlet 7 is larger than the inner diameter of exhaust gas inlet 5. Further, the inner diameters of exhaust gas inlet 5, air outlet 6, and air inlet 7 increase sequentially, thereby increasing the amount of incoming air compared to the amount of exhaust air and incoming exhaust gas, thus reducing the concentration of the exhaust gas.

[0027] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
