Description

Technical Field

[0001] The invention belongs to the technical field of gas purification, and in particular relates to a purification device for industrial waste gas. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes in the factory area of ​​an enterprise. Industrial waste gas discharged by various production enterprises is an important source of atmospheric pollutants. If a large amount of industrial waste gas is discharged into the atmosphere without being treated and meeting the standards, it will inevitably reduce the quality of the atmospheric environment, bring serious harm to human health, and cause huge losses to the national economy. Toxic and harmful substances in industrial waste gas can enter the human body through the respiratory tract and skin. Long-term low-concentration or short-term high-concentration exposure can cause temporary and permanent lesions in the respiratory, blood, liver and other systems and organs of the human body. In particular, benzopyrene polycyclic aromatic hydrocarbons can directly cause cancer in the human body, which has attracted great attention from humans. In order to meet the national standards for the discharge of waste gas and reduce pollution to the environment, industrial waste gas needs to be purified.

[0003] When purifying industrial waste gas, factories now use purification devices to treat industrial waste gas.

The coil is fixed inside the spray tower by bolts around it, and a plurality of high-pressure nozzles are installed at the bottom end of the coil, and a conduit is installed at the upper end of the spray tower, and the other end of the conduit is connected to an air pump, and the other end of the air pump is connected to the water bath through a conduit. During purification, the larger particles in the exhaust gas are first filtered through a filter box, the exhaust gas is sprayed through a spray tower, and then introduced into a water bath for water bath treatment. The quality of exhaust gas treatment can be improved after multiple treatments, but the following defects still exist: the exhaust gas in the device is filtered through a filter, but the filter is prone to clogging the mesh after working for a long time, affecting the filtering effect of the filter, and the filter needs to be cleaned regularly.

[0016] Preferably, baffles are installed on the upper and lower inner walls of the filter cylinder near the first gas pipeline and the second gas pipeline, and a small gap is left between the end of the baffle away from the filter cylinder and the filter cylinder.

[0017] The beneficial effects of the present invention are:

[0018] 1) The filter cartridge is cleaned by the cleaning mechanism, which ensures the filtering effect of the filter cartridge. The filtering work of industrial waste gas can be carried out normally while the cleaning mechanism is working, without stopping the machine for cleaning, thus improving the working efficiency of the device.

[0019] 2) A puncture mechanism is installed under the filter mechanism, and the puncture mechanism is connected to the cleaning mechanism. Since some filter holes on the filter cartridge are completely blocked by solid particles, the cleaning mechanism cannot dredge the filter holes. The blocked filter holes can be dredged under the action of the puncture mechanism. The cleaning effect of the filter cartridge is improved through the cooperation of the cleaning mechanism and the puncture mechanism.

[0020] 3) A heat exchange mechanism is installed at one end of the first gas pipeline away from the filtering mechanism. Water enters the heat exchange chamber through the water inlet pipe, and industrial waste gas enters the heat exchange part through the air inlet pipe. The industrial waste gas flows through the heat exchange part to heat the water in the heat exchange chamber, and then flows out of the heat exchange box through the first gas pipeline and enters the filtering mechanism. The water pump works to transport the water in the heat exchange chamber to the water outlet pipe through the water pipe. The whole process continues, thereby utilizing the waste heat of the industrial waste gas to heat the water.

[0021] 4) When the water pump is working, the water in the heat exchange chamber is transported to the water outlet pipe through the water delivery pipe. The flow of water in the water delivery pipe drives the paddle located inside the water delivery pipe to rotate. After the paddle rotates, it drives the first rotating shaft to rotate, and the first bevel gear located on the first rotating shaft rotates accordingly. After the first bevel gear rotates, it meshes with the second bevel gear to rotate the second rotating shaft, and the first gear located on the second rotating shaft rotates accordingly. After the first gear rotates, it meshes with the gear disk and drives the heat exchange part to rotate through the circular plate, thereby stirring the water inside the heat exchange chamber, making the water inside the heat exchange chamber heated more evenly, and improving the working efficiency of the heat exchange mechanism.

[0022] 5) Stirring blades are evenly installed in the circumferential direction of the outer periphery of the conveying pipeline. The stirring effect is improved when the stirring blades rotate in the heat exchange part. The stirring blades also increase the contact area between the conveying pipeline and the water body, which is beneficial to improve the heating efficiency of the water body.

[0023] 6) A spraying mechanism is installed above the filter mechanism. When the heat exchange part rotates, the second cam on the heat exchange part rotates accordingly. The second cam squeezes the abutment plate to drive the movable rod to move. The movable rod drives the piston to reciprocate in the piston cylinder under the action of the second spring and the second cam. When the piston moves to the left side of the piston cylinder, the negative pressure generated inside the piston cylinder sucks the purified liquid inside the purification box into the piston cylinder through the suction pipe. When the piston moves to the right side of the piston cylinder, the internal pressure of the piston cylinder transports the purified liquid to the spraying plate through the outflow pipe, and the industrial waste gas in the filter cylinder is preliminarily purified by the first nozzle. At the same time, the cleaning mechanism suppresses the dust generated when cleaning the filter cylinder, so that the dust moves to the bottom of the filter cylinder, which greatly reduces the dust from entering the purification mechanism through the second gas pipeline. The liquid formed by the dust and the purified liquid is discharged through the circular hole at the bottom of the filter cylinder.

[0024] 7) Liquid collecting covers are installed inside the support box and at both ends of the support plate. The liquid formed by dust and purified liquid is discharged through the circular hole at the bottom of the filter cylinder and falls onto the arc plate. The liquid on the arc plate can flow along the arc plate to both ends into the liquid collecting covers and finally be discharged through the drain pipe.

[0025] 8) Baffles are installed on the inner walls of the filter cylinder body on both upper and lower sides near the first gas pipeline and the second gas pipeline. A small gap is left between the end of the baffle away from the filter cylinder body and the filter cylinder, so that the industrial waste gas in the first gas pipeline can directly pass through the filter cylinder and enter the interior of the filter cylinder after being filtered, and then enter the second gas pipeline from the interior of the filter cylinder. The baffle reduces the occurrence of industrial waste gas directly entering the second gas pipeline without passing through the filter cylinder, thereby ensuring the working efficiency of the filtering mechanism.
