Abstract

The invention discloses a dehydration apparatus for treating mercury-containing sludge. The dehydration apparatus comprises a dehydration apparatus body, wherein the dehydration apparatus body is fixed on a stander, the stander consists of a first layer stander and a second layer stander, the upper end of the dehydration apparatus body is provided with a material inlet, two sides of the dehydration apparatus body are respectively provided with a stirring assembly, the stirring assembly comprises a stirring shaft, a shaft body of the stirring shaft is provided with a plurality of stirring rod bodies, the lower end of the stirring assembly is provided with an extrusion rod, and a rod body of the extrusion rod is provided with an extrusion blade. The dehydration apparatus body is internally provided with the stirring assembly and the extrusion rod, a high-efficiency dehydration effect of the mercury-containing sludge is realized by virtue of the cooperative use of the stirring shaft in the stirring assembly and the extrusion blade of the extrusion rod; and the lower end of the dehydration apparatus body is provided with a crushing shaft, so that agglomeration of the sludge after beingrapidly dehydrated in the dehydration process can be avoided.

Description

technical field [0001] The invention relates to the technical field of dehydration, in particular to a dehydration device for treating mercury-containing sludge. Background technique [0002] In recent years, with the development of my country's natural gas industry, domestic mercury-containing gas fields produce a large amount of mercury-containing sludge every year, and the treatment of mercury-containing oily sludge is an indispensable and important process link in the oil and gas field treatment system. If mercury-containing sludge in oil and gas fields is not treated in time, it will cause serious secondary pollution. Mercury is a toxic heavy metal, which is defined as Class I (extremely harmful) poison by GBZ230-2010 "Classification of Occupational Exposure to Toxic Substances". It and its various compounds are highly toxic, and will have a series of serious health effects on the human brain and nervous system, and cause serious harm to human reproductive ability and o...
