Abstract
The invention discloses an efficient waste heat recovery technological process for a chemical boiler. The efficient waste heat recovery technological process includes the following steps that S1, gas introduction in conducted, wherein high-temperature flue gas and vapor generated in the chemical boiler are introduced into an exhaust channel provided with a heat exchanger; S2, heat recovery is conducted, wherein heat absorbed by the heat exchanger is stored to a heat storage device, the heat storage device is connected with an electric energy converter, the electric energy converter is connected with a heating device of the chemical boiler, and heat in the heat storage device is converted into electric energy to be directly used for heating the chemical boiler; and S3, condensation is conducted, wherein lampblack and vapor exhausted by an exhaust channel enter a condensation device, liquid obtained through the condensation device enters a waste liquid treatment device, and gas is discharged after being treated through an air purifier and a waste gas treatment device. According to the technological process, the waste heat recovery rate is high, recovered heat is reused, waste of resources is avoided, and consumption of electric energy is saved. The technological process is simple, waste liquid and waste gas can be treated and then discharged, and pollution to the environment is avoided.
Description
Technical field
The present invention relates to chemical production technical field, particularly relate to a kind of chemical industry boiler efficient waste heat recovery process flow process.
Background technology
The heating-up temperature of chemical industry boiler is higher, the flue gas of the generation in boiler also exists carbon dioxide and oxynitride, it is emitted in air and can cause environmental pollution, and the steam in boiler can not be condensed out in time owing to the temperature in boiler is higher, be unfavorable for the use of boiler.Equipment, if do not reclaimed, both can be caused damage by the substantial amounts of waste heat that boiler in use produces, and will also result in the energy waste of heat.Existing waste heat reclaiming process is less, and most organic efficiency is the highest, and poisonous, harmful gas and steam can not get reasonably reclaiming, to environment.
Summary of the invention
The technical problem existed based on background technology, the present invention proposes a kind of chemical industry boiler efficient waste heat recovery process flow process.
Comprise the following steps；
S1: inducing QI, imports exhaust passage by the high-temperature flue gas produced in chemical industry boiler and steam, and exhaust passage is provided with heat exchanger；
S2: heat recovery, the temperature of the high-temperature flue gas in exhaust passage is down to 110～120 DEG C by heat exchanger, and the heat absorbed in heat exchanger is stored to heat storage device, heat storage device connects energy converter, electric power converter connects the heater of chemical industry boiler, heat in heat storage device changes into electric energy by electric power converter, is directly used in heating chemical industry boiler；
S3: condensation, flue gas and steam entrance condensing unit through exhaust passage discharge, water vapor condensation becomes liquid to enter liquid waste treating apparatus, air purifier is entered by the flue gas of condensing unit, free of contamination gas after air purifier processes is discharged in air, has the gas of pollution to import exhaust processor.
Preferably, described exhaust passage uses heat pipe, and heat pipe is externally provided with heat insulation layer.
Preferably, described condensing unit uses spiral circulating condensing pipe.
Preferably, described exhaust processor includes oxynitride processing system and carbon dioxide recovery pond.
The technological process of the chemical industry boiler waste heat recovery that the present invention provides, effectively reclaims the waste heat of chemical industry boiler, and technological process is simple, organic efficiency is high, and can be used for heating chemical industry boiler, plays the effect that heat circulation uses, reduce the waste of resource, save electric energy；And the harmful substance in flue gas is carried out processing by this technological process and is discharged into again in air, reduce air pollution；Waste liquid can be processed, the useful resources in waste liquid is carried out recycling, both save the energy, be avoided that again poisonous and harmful substance is discharged in river, cause water to pollute.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is explained orally further.
A kind of chemical industry boiler efficient waste heat recovery process flow process that the present invention proposes, comprises the following steps；
S1: inducing QI, imports outer layer by the high-temperature flue gas produced in chemical industry boiler and steam and is provided with the heat pipe of heat insulation layer, and heat pipe is provided with heat exchanger；
