Wet-type purification equipment for petroleum refining

Abstract

The invention relates to the technical field of petrochemical production equipment, and discloses wet purification equipment for petroleum refining. According to the technical scheme, the wet-type purification equipment for petroleum refining comprises a bottom plate and a fixing plate fixedly installed on the bottom plate, and a transverse plate parallel to the bottom plate is fixedly installed on the fixing plate. The wet-type purification equipment for petroleum refining further comprises: a spray head, wherein the spray head is movably arranged on the bottom plate; a reciprocating mechanism which is movably arranged on the bottom plate and is connected with the spray head; a lifting assembly which is connected with the reciprocating mechanism and is movably mounted on the bottom plate; and a driving mechanism which is connected with the reciprocating mechanism. Polluted gas generated in the petroleum refining process is efficiently purified, purification liquid and dust in the purification process can be automatically screened, the purification liquid can be recycled, the cost is greatly reduced, and safety and environment friendliness are achieved.

Description

technical field [0001] The invention relates to the technical field of petrochemical production equipment, in particular to a wet purification equipment for petroleum refining. Background technique [0002] The main production units in petroleum refineries usually include: crude oil distillation (atmospheric and vacuum distillation), thermal cracking, catalytic cracking, hydrocracking, petroleum coking, catalytic reforming, refinery gas processing, petroleum product refining, etc. The main production Gasoline, jet fuel, kerosene, diesel, fuel oil, lubricating oil, petroleum wax, petroleum pitch, petroleum coke and various petrochemical raw materials. A large amount of waste gas will be emitted during the petroleum refining process. The pollutant components are complex, highly toxic, diverse, concentrated and harmful. The regeneration flue gas discharged from the catalytic cracking unit of the refinery contains dust, carbon monoxide, nitrogen oxides and sulfur dioxide. Altho...

AI Technical Summary

Problems solved by technology

A large amount of waste gas will be emitted during the petroleum refining process. The pollutant components are complex, highly toxic, diverse, concentrated and harmful. The regeneration flue gas discharged from the catalytic cracking unit of the refinery contains dust, carbon monoxide, nitrogen oxides and sulfur dioxide. Although the waste gas is discharged after treatment, it cannot be 100% cleaned. As a result, the dust content and a small amount of harmful gas in the gas near the oil refinery are higher than those in other places. The dust and a small amount of harmful gas flow into the factory area and affect the work. personnel safety

In addition, the current air purification equipment in petroleum refineries purifies the polluted gas for a period of time, and the built-in filter screen needs to be replaced frequently, the consumption of purification liquid is large, the cost is high, and the operation is inconvenient. Therefore, the present invention proposes a petroleum refinery The wet purification equipment used in the production is used to solve the above problems
