Abstract
The utility model relates to a high concentration waste gas catalytic incineration system, belonging to the high concentration waste gas retrieving system and comprising a waste gas inlet pipe, an oxygenating blower, a heat economizer, a door extracting heater, a catalytic reactor and an exhaust heat boiler connected with the pipe. The utility model is provided with two waste gas preheater, the oxygenating blower is converged to connect with the waste gas inlet pipe. The first-level waste gas preheater, the second-level waste gas preheater, the door extracting heater, the catalytic reactor and the exhaust heat boiler are connected to form a smoke loop body by the pipe; while the circulating fan, the door extracting heater, the catalytic reactor, the second-level waste gas preheater and the circulating fan are connected to form an inner loop temperature controlling system by pipes. The utility model uses the circulating fan to adjust the circulating smoke, thereby controlling the reaction temperature of the catalytic reactor, which makes the temperature in the catalytic reactor maintain stability and not excess temperature, ensures the liveness of the catalyst and extends the service life of the catalyst.
Description
Technical field
The utility model belongs to high-concentration organic waste gas and purifies recovery system, relates in particular to a kind of high-concentration organic waste gas catalytic burning system of effectively guard catalyst.
Background technology
The conventional catalyst burning process is: high-concentration organic waste gas is after the oxygenating of oxygenating blower fan, heat through heat economizer again, reach and enter catalytic reactor after the catalytic reaction temperature and carry out catalytic oxidation and burn, oxidation operation in the waste gas is become the carbon dioxide and the water of environmental sound, flue gas is through the waste heat boiler recovery waste heat, and flue gas is cooled in the time of the heat economizer heat exhaust gases again.In this catalytic burning system, do not have the liquid demister, waste gas contains liquid and particle is brought in the heat economizer, and meeting fouling in heat economizer influences heat transfer efficiency or causes heat exchanger to stop up, the system that can not guarantee operation steady in a long-term.In addition, because of increasing of organic concentration in the variation of organic exhaust gas amount or the organic exhaust gas, lack the means of effectively regulating the control temperature, catalytic reactor temperature can overtemperature, and catalyst at high temperature can inactivation, has a strong impact on the service life of catalyst.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, a kind of high-concentration organic waste gas catalytic burning system is provided, this system stability, fully, energy-conserving and environment-protective, thermal efficiency height, main innovation is to increase in the system circulating fan, make catalytic reactor, secondary heat economizer, circulating fan form circulation in the flue gas, when catalytic reactor temperature raises, increase low-temperature flue gas automatically and cover catalytic reactor, reduce the temperature of catalytic reactor; When catalytic reactor temperature reduces, reduce low-temperature flue gas automatically and cover catalytic reactor, improve the temperature of catalytic reactor, pass through automatic control system, make the reaction temperature substantially constant of catalytic reactor, can not produce the problem of overtemperature, guaranteed the service life of catalytic reaction agent.Specifically implement like this: a kind of high-concentration organic waste gas catalytic burning system, comprise the exhaust inlet pipe that pipeline connects, the oxygenating blower fan, heat economizer, open the stove heater, catalytic reactor, waste heat boiler, it is characterized in that heat economizer is provided with secondary, oxygenating blower fan and exhaust inlet pipe compile the back and insert first order heat economizer, first order heat economizer, second level heat economizer, open the stove heater, catalytic reactor, waste heat boiler, first order heat economizer connects into a flue gas recirculation body, circulating fan by pipeline, open the stove heater, catalytic reactor, second level heat economizer, loop temperature-control system in circulating fan is made up of pipeline.
The utility model is removed in advance for the liquid that will contain in the organic exhaust gas and solid particulate matter, effectively prevents the structure and the obstruction of heat economizer; Be equipped with the waste gas demister before the first order heat economizer.
Organic exhaust gas separates liquid and the solid particulate matter that organic exhaust gas is carried secretly through the foam removal separator, after reaching the needed temperature of catalytic reaction, process one-level heat economizer and the preheating of secondary heat economizer enter catalytic reactor, reacted flue gas is after one enters secondary heat economizer preheating waste gas cooling, after the circulating fan supercharging, enter catalytic reactor again, take away unnecessary heat, guarantee not overtemperature of catalytic reactor, after the flue gas of another strand enters waste heat heat boiler and one-level heat economizer recovery heat energy, the flue gas qualified discharge.
The utility model is regulated the reaction temperature that amount of circulating gas is controlled catalytic reactor with circulating fan, make in the catalytic reactor temperature keep stable can overtemperature, guarantee activity of such catalysts, prolong the service life of catalyst, again by adding the liquid demister, improve heat transfer efficiency and heat exchanger is not stopped up, the operation steady in a long-term of assurance system.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to the accompanying drawings, a kind of high-concentration organic waste gas catalytic burning system, comprise the exhaust inlet pipe that pipeline connects, the oxygenating blower fan, heat economizer, open the stove heater, catalytic reactor, waste heat boiler, heat economizer is provided with secondary, waste gas is removed liquid and solid particulate matter in the waste gas through the waste gas demister, compile the back with the oxygenating blower fan and insert first order heat economizer, first order heat economizer, second level heat economizer, open the stove heater, catalytic reactor, waste heat boiler, first order heat economizer connects into a flue gas recirculation body, circulating fan by pipeline, open the stove heater, catalytic reactor, second level heat economizer, loop temperature-control system in circulating fan is made up of pipeline.After reaching the needed temperature of catalytic reactor, the preheating of waste gas process one-level heat economizer, secondary heat economizer enters catalytic reactor, the heat of flue gas mainly satisfies the caloric requirement of one-level, secondary heat economizer, superfluous heat takes waste heat boiler to reclaim, and regulates the reaction temperature that amount of circulating gas is controlled catalytic reactor by interior circulation with circulating fan in addition.
