Abstract

The invention discloses a drying and pulverizing apparatus for treating mercury-containing sludge. The drying and pulverizing apparatus comprises a body fixed on a stander, wherein the upper part in the body is provided with a feeding hopper, two ends of the feeding hopper are respectively provided with an electric heating pipe, the electric heating pipe is connected with a motor by virtue of a power supply body, the bottom end is fixedly installed on a fixed bracket, the fixed bracket is a disc-shaped double-layer fixed bracket, the lower end of the body is provided with a stirring assembly,the stirring assembly comprises a stirring shaft, one end of the stirring shaft is connected with a stirring motor outside the body, the other end of the stirring shaft is connected with a pulverizingshaft in a threading manner, and a shaft body of the pulverizing shaft is provided with a plurality of pulverizing teeth. The electric heating pipe and the stirring assembly are arranged inside the apparatus body, so that the dehydrated sludge is further dried and pulverized, automatic production is realized, the manpower cost is reduced, and the drying and pulverizing apparatus for treating themercury-containing sludge is simple in structure, high in pulverizing efficiency, relatively low in cost and convenient in market popularization and application.

Description

technical field [0001] The invention relates to sludge treatment technology, in particular to a drying and pulverizing 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 a...
