Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sulfur-containing waste gas treatment, and particularly relates to a wood pulp sponge production sulfur-containing waste gas treatment system. BACKGROUND

[0002] In wood pulp sponge production, sulfur-containing waste gas mainly comes from raw material pretreatment (such as decomposition of sulfur-containing compounds), chemical reaction process (such as volatilization or reaction of sulfur-containing reagents such as carbon disulfide) and by-products that may be produced in the production process. If these waste gases are directly discharged without treatment, they will pollute the environment.

[0003] The existing sulfur-containing waste gas treatment system has the following problems: When the existing sulfur-containing waste gas treatment system uses a physical method to purify sulfur-containing waste gas, it cannot reduce the sensitivity of physical adsorbents to waste gas concentration, so that high-concentration sulfur-containing waste gas can cause a sharp decline in the adsorption efficiency of physical adsorbents, thereby failing to effectively remove pollutants, thereby reducing the purification efficiency of sulfur-containing waste gas, and thus cannot meet the use requirements of the existing sulfur-containing waste gas treatment system. SUMMARY

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present application provides a wood pulp sponge production sulfur-containing waste gas treatment system which can adjust the mixing amount of external air according to the concentration of sulfur-containing waste gas, thereby diluting the sulfur-containing waste gas and improving the purification efficiency of physical adsorbents for sulfur-containing waste gas.

[0005] The technical scheme adopted by the present application is as follows: The wood pulp sponge production sulfur-containing waste gas treatment system provided by the present application comprises a fixing frame, a flow guide frame, an adsorption frame, a capacity-changing waste gas suction mechanism and a gas distribution type purification mechanism, the flow guide frame is symmetrically arranged on one side of the fixing frame, the adsorption frame is arranged on the side of the fixing frame away from the flow guide frame, the capacity-changing waste gas suction mechanism is arranged on the flow guide frame, and the gas distribution type purification mechanism is arranged on the adsorption frame. The capacity-changing waste gas suction mechanism comprises a telescopic assembly, a waste gas assembly and a capacity-adjusting assembly, the telescopic assembly is arranged on the inner wall of the flow guide frame, the waste gas assembly is arranged on the side of the flow guide frame away from the fixing frame, and the capacity-adjusting assembly is arranged in the telescopic assembly. The gas distribution type purification mechanism comprises an exhaust assembly, a gas conversion assembly, a dilution assembly and a filter assembly, the exhaust assembly is arranged on the bottom side wall of the fixing frame, the gas conversion assembly is arranged on the top side wall of the fixing frame, the dilution assembly is arranged between the exhaust assembly and the gas conversion assembly, and the filter assembly is arranged on the inner wall of the adsorption frame.

[0006] As a further preferred embodiment of the present invention, the telescopic assembly includes a positioning middle section cylinder, an upper telescopic cylinder and a lower telescopic cylinder. The positioning middle section cylinder is arranged on the inner wall of the guide frame, and the positioning middle section cylinder is a through-set cavity. The upper telescopic cylinder is connected to the upper wall of the positioning middle section cylinder, and the lower telescopic cylinder is connected to the bottom wall of the positioning middle section cylinder; the exhaust gas assembly includes an exhaust gas hose, a pipe clamp, an intake pipe, an intake fan and a gas composition detection sensor. The exhaust gas hose is connected to the upper wall of the upper telescopic cylinder, the pipe clamp is arranged on the side of the guide frame away from the fixed frame, the intake pipe is penetrated by the inner wall of the pipe clamp, and one end of the exhaust gas hose away from the upper wall of the upper telescopic cylinder is connected to the intake pipe, and the intake fan is arranged on the intake pipe The gas composition detection sensor is arranged on the inner wall of one end away from the exhaust hose, and the gas composition detection sensor is arranged on the side of the pipe clamp away from the guide frame. The detection end of the gas composition detection sensor passes through the pipe clamp and is arranged inside the intake pipe; the capacity adjustment component includes a capacity adjustment frame, a shrinking spring, a capacity adjustment electromagnet and an extension magnet. The capacity adjustment frame is arranged on the inner wall of the positioning middle section of the cylinder, and the shrinking spring is respectively arranged between the upper wall of the capacity adjustment frame and the top wall of the upper telescopic cylinder and between the bottom wall of the capacity adjustment frame and the bottom wall of the lower telescopic cylinder. The shrinking spring is normally shortened. The capacity adjustment electromagnet is symmetrically arranged on the upper and bottom walls of the capacity adjustment frame outside the shrinking spring. The extension magnet is respectively arranged on the top wall of the upper telescopic cylinder outside the shrinking spring and the bottom wall of the lower telescopic cylinder outside the shrinking spring.

[0007] During use, in the initial state, the upper telescopic cylinder and the lower telescopic cylinder are respectively retracted, and the volume of the cavity formed by the positioning middle cylinder, the upper telescopic cylinder and the lower telescopic cylinder is at the minimum value. The suction fan absorbs the sulfur-containing waste gas generated in the production process of wood pulp sponge, and the sulfur-containing waste gas enters the cavity formed by the positioning middle cylinder, the upper telescopic cylinder and the lower telescopic cylinder through the suction pipe and the waste gas hose. When the sulfur-containing waste gas flows through the inside of the suction pipe, the gas composition detection sensor monitors the sulfur concentration of the sulfur-containing waste gas inside the suction pipe in real time through the detection end.

[0008] The exhaust gas fan of the present invention is connected with the exhaust gas fan of the present invention on the outer wall of the air filter, and the exhaust gas fan of the present invention is connected with the exhaust gas fan of the present invention on the outer wall of the air filter.

The gas conversion box flows the sulfur-containing waste gas into the filter tube through the gas conversion hose. The sulfur-containing waste gas inside the filter tube is adsorbed by the activated carbon adsorption layer and then discharged from the one-way purification valve.

[0010] Specifically, a controller is provided on the upper wall of the gas conversion box.

[0011] Wherein, the controller is electrically connected to the suction fan, the gas composition detection sensor and the capacitance adjustment electromagnet respectively.

[0012] The beneficial effects achieved by adopting the above structure are as follows: Compared with the existing technology, this solution adopts a combination of a volume-adjustable structure and a fast-flow air suction structure. Through the provision of a volume-changing waste suction mechanism and a gas distribution purification mechanism, the coordinated use of the telescopic component, the waste gas component, the volume-adjusting component, the exhaust component, the gas conversion component, the dilution component and the filter component can pre-regulate the concentration of sulfur gas in the sulfur-containing waste gas entering the activated carbon adsorption layer, thereby improving the filtration efficiency of the activated carbon adsorption layer for sulfur-containing waste gas. The sulfur-containing waste gas flowing inside the dilution tube at high speed generates a negative pressure, and the dilution tube uses the generated negative pressure to absorb external air through a one-way air intake valve, thereby being able to dilute the concentration of sulfur gas in the sulfur-containing waste gas entering the dilution tube, thereby reducing the sensitivity of the activated carbon adsorption layer to the waste gas concentration, and avoiding the high concentration of sulfur-containing waste gas causing the adsorption efficiency of the activated carbon adsorption layer to drop sharply, making it impossible to effectively remove pollutants, thereby improving the purification efficiency of the activated carbon adsorption layer for sulfur-containing waste gas to a certain extent.

[0021] A controller 20 is provided on the upper wall of the gas conversion box 26 .

[0022] The controller 20 is electrically connected to the air intake fan 13 , the gas component detection sensor 14 , and the capacitance adjustment electromagnet 18 , respectively.

[0023] During specific use, in the initial state, the upper telescopic cylinder 7 and the lower telescopic cylinder 8 are respectively retracted, and the volume of the cavity formed by the positioning middle cylinder 6, the upper telescopic cylinder 7 and the lower telescopic cylinder 8 is the minimum value. The controller 20 controls the suction fan 13 to start, and the suction fan 13 absorbs the sulfur-containing waste gas generated in the production process of wood pulp sponge. The sulfur-containing waste gas passes through the suction pipe 12 and the exhaust hose 10 into the cavity formed by the positioning middle cylinder 6, the upper telescopic cylinder 7 and the lower telescopic cylinder 8. When the sulfur-containing waste gas flows through the interior of the suction pipe 12, the controller 20 controls the gas composition detection sensor 14 to start, and the gas composition detection sensor 14 monitors the sulfur concentration of the sulfur-containing waste gas inside the suction pipe 12 in real time through the detection end; When the gas component detection sensor 14 detects that the concentration of sulfur gas in the sulfur-containing waste gas in the suction pipe 12 exceeds the value specified by the operator, the controller 20 controls the activation of the volume adjustment electromagnet 18 arranged on the upper wall and the bottom wall of the volume adjustment frame 16, and the controller 20 controls the increase of the current flowing into the volume adjustment electromagnet 18.

The stretching magnet 19 drives the upper telescopic cylinder 7 and the lower telescopic cylinder 8 to stretch away from one end of the positioning middle cylinder 6 by using the deformation of the telescopic spring 17. The volume of the cavity formed between the positioning middle cylinder 6, the upper telescopic cylinder 7 and the lower telescopic cylinder 8 increases. Under the same inflation speed and discharge conditions, the exhaust speed of the large container is faster during continuous inflation and discharge, so that the flow speed of the sulfur-containing waste gas discharged from the cavity after increasing the volume is accelerated. The sulfur-containing gas with a faster flow rate generates negative pressure when flowing through the inside of the dilution pipe 30. The dilution pipe 30 extracts air from the outside through the one-way air inlet valve 31, and the air mixes with the flowing sulfur-containing waste gas, thereby diluting the concentration of sulfur gas in the sulfur-containing waste gas and reducing the sensitivity of the activated carbon adsorption layer 35 to the concentration of the waste gas. This avoids the sharp decline in the adsorption efficiency of the activated carbon adsorption layer 35 caused by high-concentration sulfur-containing waste gas, so that the activated carbon adsorption layer 35 can effectively remove pollutants. The diluted sulfur-containing waste gas enters the inside of the gas conversion tank 26, and the gas conversion tank 26 flows the sulfur-containing waste gas into the inside of the filter cylinder 33 through the gas conversion hose 27. The sulfur-containing waste gas in the inside of the filter cylinder 33 is adsorbed by the activated carbon adsorption layer 35 and discharged from the one-way purification valve 34. The above operation can be repeated next time.
