Plastic granulating waste gas purifying device

Abstract

The invention relates to a plastic granulating waste gas purifying device, and belongs to the technical field of waste gas purifying equipment. The waste gas purifying device comprises a gas collecting cover, a vacuum pump, a primary purifying water tank and a secondary purifying water tank, wherein the gas collecting cover is communicated with the primary purifying water tank via a primary communicating pipe; the primary purifying water tank is communicated with the secondary purifying water tank via a secondary communicating pipe; the secondary communicating pipe is provided with the vacuum pump. The waste gas purifying device is simple in structure; when in operation, harmful gases generated in the plastic granulating process are purified completely under the effect of the vacuum pump via full contact with water bodies in the primary purifying water tank and the secondary purifying water tank, and then meet the requirements of emission standard and environment protection; the defects that the existing waste gas purifying device is high in cost and is complex in device structure are solved, and the problems that the treatment effect is not ideal and cannot meet the emission standard and the environment protection requirement are also solved; the plastic granulating waste gas purifying device is particularly suitable for the purification of plastic granulating waste gas.

Description

technical field [0001] The invention relates to a plastic granulation waste gas purification device, which belongs to the technical field of waste gas purification equipment. Background technique [0002] During the processing of plastics, large quantities of harmful gases (smoke) containing dust particles are generated. Because these harmful gases are polluting, direct discharge into the air will not only cause physical harm to the staff, but also pollute the environment. Under normal circumstances, manufacturers will use exhaust gas purification equipment to purify harmful gases; in order to meet the emission standards as much as possible. Although the existing exhaust gas purification equipment can purify harmful gases, most of them have the disadvantages of high processing cost, unreasonable equipment structure, and unsatisfactory treatment effect, which cannot meet the emission standards and environmental protection requirements. Therefore, it is necessary to develop a...
