Closed efficient waste heat utilization circulating system of humid air turbine compressor

Abstract

The invention discloses a closed efficient waste heat utilization circulating system of a humid air turbine compressor. The closed efficient waste heat utilization circulating system comprises a humidair compressor turbine compression-expansion system and a humid air gas-water separation system. The humid air compressor turbine compression-expansion system comprises a stop valve I, a regulating valve and a humid air turbine which are communicated with an outlet of a drying chamber. The wet air compressor turbine compression-expansion system further comprises a wet air compressor communicatedwith an inlet of the drying chamber through a stop valve VIII. The humid air gas-water separation system comprises a humid air gas-water separator, and the humid air gas-water separator is communicated with a vacuum water storage tank. The system has the beneficial effects that waste gas can circulate in the closed system, pollutants such as dust and toxic and harmful waste gas are prevented frombeing discharged into the atmosphere, so that the effect of protecting the environment is achieved, heat energy in the waste gas can be recycled, the energy utilization rate is increased, 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...

AI Technical Summary

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.
