Abstract

The invention provides a heating device for tank cleaning oil-containing sludge in a gas field. The heating device comprises a device body, a pretreatment device and a device top plate, wherein the device body is a cylindrical chamber of which the upper end is provided with an opening; the device top plate is positioned at the upper end of the device body, and the lower end of a sludge funnel of the pretreatment device penetrates through the device top plate and is communicated with the interior of the device body; a heating medium circulating pipeline is arranged in the device body; a stirring device is arranged in the device body, and an upper chamber transverse separating plate and a lower chamber transverse separating plate are arranged on the inner wall of the device body, and a chamber vertical separating plate is arranged at the lower end of the center of the lower chamber transverse separating plate; a waste liquid overflow drain pipe is arranged at the lower end of the lower chamber transverse separating plate, and a waste slag discharge pipeline is arranged at the bottom part of the device body. The heating device has the advantages that the absolute safety of a heat source is realized, the quick heating effect is realized, the heat source is isolated from the heated sludge, and pretreatment conditions of subsequent sludge treatment can be met.

Description

technical field [0001] The invention relates to the field of low-permeability gas field development, in particular to a gas field tank cleaning oily sludge heating device. Background technique [0002] In the process of natural gas extraction, there are a large amount of mud, fine sand, corrosion products, and residues of gas field chemical additives in the storage process. They are carried out of the wellhead with the gas flow, and sludge is formed after precipitation in the natural gas treatment plant. The oily sludge in gas fields mainly comes from tank cleaning bottom sludge, pipe pigging sludge, and station equipment cleaning sludge of wastewater treatment equipment in natural gas treatment plants. [0003] Since gas field tank cleaning sludge is a mixture of high oil content, high emulsification, and high water content, it is difficult to treat it harmlessly through evaporation and incineration under natural conditions. Efficient processing technology. Chemical demul...
