Description

Technical Field

[0001] The utility model relates to the technical field of gas emission processing equipment, in particular to a gas emission device in the waste mineral oil purification process. Background Art

[0002] A small amount of flammable non-condensable gas will be produced during the purification process of waste mineral oil. These flammable non-condensable gases are difficult to recycle through condensation. For large-scale professional waste mineral oil treatment plants, special flammable non-condensable gas recovery systems can be used to collect and utilize them. However, small-scale waste mineral oil treatment plants or waste mineral oil treatment stations of oily sludge treatment plants directly discharge flammable non-condensable gases into the atmosphere. These combustible gases contain toxic and harmful gases, which seriously pollute the environment.

[0003] In this regard, the Chinese utility model patent with the authorization announcement number CN208911683U discloses a gas emission device in the waste mineral oil purification process, including a refrigerator and a filter tank, the filter tank is provided with an air intake pipe extending to the bottom of the filtered water, and the air intake pipe located at the bottom of the filtered water is provided with uniformly distributed air holes; the top of the filter tank is provided with a spiral exhaust pipe, the spiral pipe part of the spiral exhaust pipe is located in the condensing box, the bottom of the condensing box is connected to the refrigerator through a pipeline, the top of the condensing box is provided with a discharge pipe, the top of the spiral exhaust pipe is welded to the combustion pipe, the top of the combustion pipe is provided with a combustion nozzle, a fireproof cover is provided above the combustion nozzle, and a regulating valve is installed on the combustion pipe. The emission device first filters the combustible non-condensable gas through the filter tank, filters out most of the solid particles such as smoke and dust mixed in the combustible gas, and the filtered combustible gas is discharged into the atmosphere after being burned through the torch combustion tube. Compared with direct emission, the combustion of the combustible gas and then discharged greatly reduces the degree of pollution to the environment.

[0004] When filtering, the device will produce solid sediments that remain inside the filtering device and are difficult to clean. For this reason, we propose a gas emission device during the waste mineral oil purification process to solve the above problem. Utility Model Content
