Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas collection device for waste gas treatment. Background Art

[0002] Waste gas treatment is an important environmental protection work for pre-treating the waste gas generated in industrial sites, factory workshops, etc. before discharging it to meet the national waste gas emission standards. Waste gas treatment covers many aspects, including organic waste gas treatment, dust waste gas treatment, acid-base waste gas treatment, odor waste gas treatment, and air sterilization and purification. There are various methods for waste gas treatment, and the commonly used methods include the condensation method, absorption method, combustion method, catalytic method, adsorption method, etc. Condensation method: mainly used for recovering valuable organic substances. By lowering the temperature of the waste gas, some components in it condense into liquid, so as to be recovered. Absorption method: by contacting the waste gas with a specific absorbent, the harmful substances in the waste gas are absorbed by the absorbent, so as to achieve the purpose of purifying the waste gas. This method can be divided into chemical absorption and physical absorption. Adsorption method: uses porous solid substances (such as activated carbon) to adsorb harmful substances in the waste gas to achieve the effect of purifying the waste gas. When the adsorbent is saturated, it can be desorbed and regenerated by a certain method for recycling. Waste gas treatment equipment is widely used in many industries, such as chemical industry, electric power, iron and steel, food and beverage, medicine and biopharmaceutics, electronics and semiconductors, etc. The waste gas generated in the production process of these industries has complex components and needs to be treated by professional waste gas treatment equipment to meet the environmental protection requirements.

[0003] During the process of waste gas treatment, it is necessary to collect the waste gas. Since it is necessary to ensure the collection effect, but considering that it is not convenient to adjust the air collecting hood during the process of waste gas collection and it is not convenient to accurately collect the waste gas at different positions, some positions will not be collected comprehensively, which is extremely inconvenient. Therefore, there is an urgent need for a waste gas collection device for waste gas treatment to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a waste gas collection device for waste gas treatment, which solves the problem that in the prior art, when adjusting the welding pipe support, it is not convenient to adjust the height of the support up and down, so that the welding pipe cannot be welded at different positions during use, and thus greatly reduces the welding efficiency of the welding pipe.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An exhaust gas collection device for exhaust gas treatment, comprising a base, on one side of the top of the base is fixedly connected with a collection box, and on one side of the collection box is fixedly connected with a side frame. At the top of the side frame is provided a gas collection hood, and on one side inside the side frame is fixedly connected with a fixing plate. And at the bottom of the fixing plate is fixedly connected with a driving motor through bolts. Inside the side frame is rotatably connected with a rotating rod, and the top end of the rotating rod passes through the top of the side frame and is fixedly connected between the bottom of the gas collection hood. And the bottom end of the rotating rod passes through the fixing plate and is in transmission connection with the output shaft of the driving motor. The top of the collection box is communicated with the top of the gas collection hood. On one side of the top of the base is fixedly connected with a fan through bolts, and the inlet of the fan is communicated with the lower part of one side of the collection box.

[0007] Preferably, both sides at the bottom of the gas collection hood are fixedly connected with sliders, and the sliders are slidably connected with the top of the side frame through slide rails.

[0008] Preferably, both the top end and the bottom end of the rotating rod pass through the top of the side frame and the fixing plate in sequence through bearing sleeves.

[0009] Preferably, a door body is rotatably connected to the outside of one side of the collection box through a hinge.

[0010] Preferably, several adsorption plates are fixedly connected inside the collection box, and all the adsorption plates are distributed vertically.

[0011] Preferably, the top of the collection box is communicated with the top of the gas collection hood through a connecting hose.

[0012] The utility model at least has the following beneficial effects:

[0013] When the exhaust gas collection device for exhaust gas treatment of the utility model is in use, first move the required base and components to the position where the exhaust gas needs to be collected. Start the fan to absorb the exhaust gas into the collection box through the gas collection hood, and use the collection box and its components to collect and adsorb the exhaust gas. At the same time, the driving motor can be started to drive the gas collection hood to rotate and adjust through the rotating rod, so that the exhaust gas at different positions can be collected, improving the effect of exhaust gas collection. Compared with the prior art, when adjusting the welding pipe support, it is not convenient to adjust the height of the support up and down, which will cause the welding pipe to be unable to be welded at different positions during use, and thus greatly reduce the welding efficiency of the welding pipe. The method proposed in the utility model collects and adsorbs the exhaust gas through the collection box and its components, and at the same time, the gas collection hood rotates and adjusts, so that the exhaust gas at different positions can be collected, improving the effect of exhaust gas collection, and has high practicability.
