Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and particularly relates to a petrochemical waste gas treatment device. Background Art

[0002] The petrochemical industry, abbreviated as petrochemicals, generally refers to the chemical industry with petroleum and natural gas as raw materials. It has a wide range and many products. After crude oil is cracked (cracked), reformed and separated, it provides basic raw materials such as ethylene, propylene, butene, butadiene, benzene, toluene, xylene, naphthalene, etc. It is an important part of the chemical industry and plays an important role in the development of the national economy. It is one of the pillar industrial sectors in China. Petrochemicals refers to the processing industry that uses petroleum and natural gas as raw materials to produce petroleum products and petrochemical products. Petroleum products, also known as oil products, mainly include various fuel oils (such as gasoline, kerosene, diesel, etc.), lubricating oils, liquefied petroleum gas, petroleum coke, paraffin, asphalt, etc. The processing processes for producing these products are often referred to as petroleum refining, abbreviated as oil refining.

[0003] In the petrochemical industry, a large amount of waste gas is generated. Therefore, a waste gas collection and treatment system for petrochemicals is needed to meet the current market demand. Although a variety of waste gas collection and treatment systems have been produced on the market, generally speaking, there are still many common problems. First, most of the existing waste gas collection and treatment systems only have a single-layer filtering device inside, resulting in the inability to completely filter the impurities in the waste gas. Second, most of the existing waste gas collection and treatment systems adopt an integrated structure, resulting in the inability of workers to disassemble the device to replace the filter layer. Summary of the Invention

[0004] The purpose of the present invention is to solve the above-mentioned shortcomings in the technology. The technical solution adopted by the present invention is as follows:

[0005] A petrochemical waste gas treatment device includes a treatment box with a plurality of support rods provided below. The bottom ends of the support rods are provided with rollers. A plurality of sliding grooves are equidistantly arranged inside the treatment box. One of the sliding grooves is inserted with a first filter plate, one of the sliding grooves is inserted with a second filter plate, and one of the sliding grooves is inserted with a third filter plate. One end of the treatment box with an opening is provided with a cover plate. A bolt is screwed at a position near the bottom end of the cover plate, and one end of the bolt is screwed into the inside of the treatment box by threads. An exhaust pipe is provided at the top end of the treatment box, and an intake pipe is provided at the bottom end of the treatment box.

[0006] Preferably, a hinge is provided at the top end of the cover plate and is movably connected to the upper surface of the treatment box through the hinge. A baffle is provided on the side of the cover plate close to the treatment box. A sealing strip is sleeved outside the baffle, and the outer circle of the sealing strip abuts against the inner side of the opening end of the treatment box.

[0007] Preferably, a plurality of fixing grooves are equidistantly arranged at one end of the treatment box away from the cover plate, and the fixing grooves communicate with the inner side of the sliding groove. A spring is arranged inside the fixing groove, and a slider is arranged at one end of the spring. The slider can move freely inside the fixing groove and the sliding groove.

[0008] The beneficial effects of the present invention are as follows:

[0009] For a petrochemical waste gas treatment device of the present invention, by arranging a first filter plate, a second filter plate and a third filter plate inside the treatment box, the filtering effect of the waste gas is further improved. At the same time, the cover plate arranged at one end of the treatment box can be opened, so that the components inside the treatment box can be replaced. Description of the Drawings
