A Closed High Efficiency Waste Heat Utilization Circulation System of Humid Air Turbine Compressor

Abstract

The invention discloses a humid air turbine compressor closed-type high-efficiency waste heat utilization circulation system, comprising a humid air compressor turbo compression-expansion system and a wet air gas-water separation system; the humid air compressor turbo compression-expansion system; The expansion system includes a shut-off valve I, a regulating valve and a humid air turbine connected to the outlet of the drying chamber; the humid air compressor turbine compression-expansion system also includes a humid air compressor connected to the inlet of the drying chamber through a shut-off valve VIII; The wet air gas-water separation system includes a wet air gas-water separator, and the wet air gas-water separator is communicated with a vacuum water storage tank. The beneficial effects of the present invention are: this scheme can make the waste gas circulate in the closed system, avoid dust, toxic and harmful waste gas and other pollutants from entering the atmosphere, thereby protecting the environment, and the heat energy in the waste gas can be recycled and improved. The energy utilization rate is improved, and the production cost can be effectively reduced.

Description

technical field [0001] The invention relates to the field of recovery of industrial drying waste heat, in particular to a closed-type high-efficiency waste heat utilization cycle system of a humid air turbine compressor. Background technique [0002] The drying process is widely used in chemical manufacturing and materials, pharmaceuticals, food, light industry, environmental protection and other industries. In the ceramic industry, the spray drying tower is one of the main equipment in the drying and granulation process of ceramic production. This process uses coal powder as fuel and uses the hot flue gas generated by combustion in the hot blast stove to provide heat for granulation; in the pharmaceutical industry, spray Drying is usually used for drug drying and granulation and preparation of microcapsules; in the food industry, spray drying is usually used in the production of fruit and vegetable powder, instant tea beverages, food additives, health food, and also in othe...

Problems solved by technology

[0003] The principle of the drying process is basically the same. The common problems faced by the production system are the large energy waste and the difficulty in the treatment of exhaust gas and dust. It is imminent for the production department to design an environmentally friendly spray drying system that can directly replace the original spray drying system and has the ability to solve environmental pollution and energy waste during the drying process.
