Abstract

The invention discloses low-temperature waste heat treatment equipment for dried tail gas. The low-temperature waste heat treatment equipment comprises a tail gas treatment chamber, wherein the tail gas treatment chamber is sequentially equipped with a vacuum flash-evaporation section, a spraying and heat-collecting section, an atomizing and dust-collecting section and an electrostatic dust-collecting section from bottom to top; tail gas enters the spraying and heat-collecting section, heat is enriched by circulating water, the circulating water enters the vacuum flash-evaporation section to generate negative-pressure steam, and the negative-pressure steam is used as a heat source of a vacuum heat pump in the vacuum flash-evaporation section; and after the circulating water is cooled through flash-evaporation treatment, the circulating water is conveyed through the vacuum heat pump and is circulated, cooled tail gas sequentially enters the atomizing and dust-collecting section and theelectrostatic dust-collecting section for being further subjected to dust collection, and part of tail gas which passes through the electrostatic dust-collecting section is introduced into the spraying and dust-collecting section.

Description

technical field [0001] The invention relates to the fields of tail gas treatment and the like, in particular to low-temperature waste heat treatment equipment for drying tail gas. Background technique [0002] Material drying is one of the important production processes of chemical enterprises. Its purpose is to remove the moisture in some raw materials, semi-finished products and finished products, so that the materials are convenient for packaging, transportation, storage, processing and use. The drying process involves many fields such as chemical industry, petrochemical, pharmaceutical, food, papermaking, wood, food and agricultural by-product processing, building materials, and environmental protection. Since drying is to vaporize and remove the moisture in the material by means of heating, drying is one of the unit operations with high energy consumption. According to statistics, the sum of drying energy consumption in various industries in the UK accounts for about 8...
