Description

Technical Field

[0001] The invention relates to the technical field of gas purification, and in particular to a sulfur-containing odor treatment device. Background Art

[0002] Sulfur-containing gases (such as H2S, CS2, COS, mercaptan, sulfide, thiophene, etc.) mainly come from industries such as metallurgy, chemical industry, oil refining, mining, waste incineration, boilers and automobiles. SO2 is one of the most important environmental pollutants and the main cause of acid rain. SO2 can destroy the physiological functions of plants and slow down the growth of crops and forests. When humans inhale high concentrations of SO2 gas, it will have a strong irritating effect on the respiratory tract. Therefore, SO2, as the main atmospheric pollutant, has been widely valued for its emission control technology. The direct emission of sulfur-containing gases without desulfurization treatment will harm human health and damage the ecological environment, while the direct use of sulfur-containing gases with utilization value will seriously corrode production equipment. At present, with the gradual improvement of environmental awareness, especially for heavy industry, especially the steel industry, most environmental protection equipment uses activated carbon adsorption towers to treat waste gas, especially through the activated carbon adsorption towers set in the activated carbon adsorption towers, and the activated carbon adsorption layer is used to adsorb the waste gas generated in industrial production, so as to meet the increasingly stringent atmospheric emission standards.

[0003] A Chinese patent document with authorization announcement number CN114588744B discloses an activated carbon adsorption system that is convenient for loading activated carbon, which belongs to the field of waste gas treatment, and includes a box body, which is connected to a gas mixing box through a connecting pipe, and a gas mixing and distribution mechanism is provided in the gas mixing box, at least two groups of activated carbon adsorption components are provided in the box body, a circulation mechanism coordinated with the activated carbon adsorption components is provided in the box body, and an activated carbon input mechanism and an activated carbon output mechanism coordinated with the activated carbon adsorption components are provided on the rear side of the box body; the box body is provided with a gas input chamber, a gas input chamber and a gas transport chamber, and the two groups of activated carbon adsorption components are respectively located between the gas input chamber and the gas transport chamber and between the gas output chamber and the gas transport chamber. The invention facilitates the replacement of the activated carbon adsorption material in the activated carbon frame through its unique structural design, and then realizes the automatic replacement of the activated carbon material in the activated carbon adsorption component.

[0004] When the existing activated carbon adsorption device is in use, the activated carbon closest to the air inlet is most likely to become clogged and adsorbed to saturation. Therefore, the activated carbon needs to be replaced after a period of use to avoid affecting the adsorption effect. However, replacing all of them will result in a waste of some activated carbon that is not fully used. If only the activated carbon at the air inlet is replaced, it is impossible to determine whether the activated carbon in other parts needs to be replaced, so it is inconvenient to use. Summary of the invention

[0005] The present invention provides a sulfur-containing odor treatment device, aiming to solve the problem in the related art that the activated carbon closest to the air inlet is most prone to clogging and adsorption saturation, so the activated carbon needs to be replaced after being used for a period of time.

The air inlet mesh belt and the air outlet mesh belt are respectively located at one end of the inner and outer rings of the annular accommodating cavity away from each other. When the front baffle and the rear baffle rotate, the side of conveyor belt 1 / conveyor belt 2 that contacts the activated carbon moves synchronously with the activated carbon.

[0007] The effect is that the waste gas to be treated enters the annular containing chamber through the air inlet mesh belt, then undergoes the activated carbon adsorption treatment in the annular containing chamber, and finally passes through the air outlet mesh belt. When the adsorption effect decreases, the front baffle and the rear baffle rotate to rotate the activated carbon inside, and at the same time, the inner sides of conveyor belt 1, conveyor belt 2, annular filter screen 1 and annular filter screen 2 are attached to the activated carbon and driven synchronously, thereby avoiding confusion of the activated carbon at the edge during rotation, so that the activated carbon that was originally attached to the inner side of the annular filter screen 1 and has a higher degree of use is rotated to one side by a certain angle, thereby avoiding excessive decrease in the adsorption effect and fully utilizing the activated carbon.

[0011] Preferably, the transmission mechanism includes gear one respectively installed at both ends of shaft one and shaft three, and also includes gear two respectively installed at both ends of shaft two and shaft four. The front baffle and the rear baffle are fixedly mounted with outer gear rings and inner gear rings, the outer gear ring is meshed with gear one, and the inner gear ring is meshed with gear two. The effect is that when the front baffle and the rear baffle rotate, the conveyor belt one, the air inlet mesh belt, the conveyor belt two and the air outlet mesh belt are driven to run through the outer gear rings and the inner gear rings.

[0012] Preferably, the driving device comprises a motor mounted on a bracket, and a gear three meshing with an outer gear ring is fixedly mounted on the output end of the motor.

[0014] Preferably, one end of the arc plate three is hinged to the arc plate one, and the top of the bracket is provided with a telescopic pipe for docking with the annular filter one, which has the effect of facilitating the replacement of the connection between the front and rear air inlets of the activated carbon and the exhaust gas outlet.

[0015] Preferably, a convex strip that abuts against the bottom of the telescopic pipe is provided on the side of the arc plate 3. The effect is that the convex strip abuts against the telescopic pipe, thereby closing the arc plate 3 and preventing the arc plate 3 from opening.

[0016] Preferably, a sealing strip is provided at the bottom outlet of the telescopic pipe.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. When the adsorption effect decreases, start the motor to rotate gear 3, so that the outer gear ring rotates with the front baffle, the rear baffle and the inner gear ring. The rotation of the front baffle and the rear baffle rotates the activated carbon inside. At the same time, due to the rotation of the outer gear ring and the inner gear ring, gear 1 and gear 2 rotate, so that the inner sides of conveyor belt 1, conveyor belt 2, annular filter 1 and annular filter 2 are attached to the activated carbon and driven synchronously, so as to avoid confusion of the activated carbon at the edge during rotation, so that the activated carbon that was originally attached to the inner side of the annular filter 1 and has a higher degree of use is rotated to one side at a certain angle, so as to avoid excessive decrease in the adsorption effect and prevent excessive impurities in the original position from affecting gas circulation.

After it is completely discharged, the pin is pulled out and reset, and the air intake mesh belt is rotated to the top, the pin is inserted, and then new activated carbon is poured in. At the same time, the motor is started to rotate the front baffle and the rear baffle, and the conveyor belts 1 and 2 are driven to completely fill the containing chamber with activated carbon, and then the air intake mesh belt is closed, and the telescopic pipe is extended again to press the arc plate 3, thereby completing the replacement of the activated carbon.
