The invention discloses a kind of chemical industry boiler efficient waste heat recovery process flows, include the following steps；S1：The high-temperature flue gas generated in chemical industry boiler and vapor are imported the exhaust passage equipped with heat exchanger by air guide；S2：Heat recovery, the heat absorbed in heat exchanger are stored to heat storage device, and heat storage device connects energy converter, and electric power converter connects the heating device of chemical industry boiler, and the converting heat in heat storage device is directly used in heating chemical industry boiler at electric energy；S3：Condensation, flue gas and vapor through exhaust passage discharge enter condensing unit, and the liquid that condensed device obtains enters liquid waste treating apparatus, and gas discharges again after the processing of air purifier and exhaust processor.Technological process provided by the invention, waste heat recovery rate is high, and the heat of recycling can be recycled, and avoids the wasting of resources, saves power consumption, the technological process is simple, can handle waste liquid, exhaust gas and discharge again, avoid environmental pollution.
Description
Technical field
The present invention relates to chemical production technical field more particularly to a kind of chemical industry boiler efficient waste heat recovery process flows.
Background technology
The heating temperature of chemical industry boiler is higher, and there is carbon dioxide and nitrogen oxidation to close in the flue gas of the generation in boiler
Object, environmental pollution can be caused by being emitted into air, and the vapor in boiler due to the temperature in boiler it is higher cannot in time it is cold
It coagulates, is unfavorable for the use of boiler.The a large amount of waste heat that boiler generates in use, both can be to equipment such as without recycling
It damages, will also result in the energy waste of heat.Existing waste heat reclaiming process is less, and most organic efficiency is not high,
Toxic, pernicious gas and vapor cannot be recycled reasonably, be polluted the environment.
Invention content
