Description
Technical field
The present invention relates to a kind of organic exhaust gas handles and the heat energy recycle system.
Background technology
The technological principle of heat accumulating type heating power oxidation furnace system (being called for short RTO) is: the hydrocarbon organic solvent directly burns through 760-850 ℃ of temperature and makes it complete heating power oxidation, and the holdup time is 0.3-1.2 second (being direct burning RTO duty).Under this high temperature, oxidized carbon dioxide and the water of being decomposed into of the organic matter in the waste gas.
Conventional heat accumulating type heating power oxidation furnace system process is an example with the rotary valve type oxidation furnace, and the key problem in technology of heat accumulating type heating power oxidation furnace is to adopt the high-efficiency heat-accumulating combustion system.This system by the combustion chamber, (5 lattice are air inlet area, and 5 lattice are for going out the gas area, and remaining 2 lattice is purge zone, and purge zone has been separated air inlet area and closed out the gas area to be divided into the energy storage bed of 12 lattice.) and 1 rotary valve composition.Filled honeycomb ceramic heat-storing material in the energy storage bed, desire processing gas is introduced into energy storage bed (air inlet area) from the rotary valve inlet and is preheated to uniform temperature, through the real-time detection of thermocouple B; Judge that whether this desire processing gas has reached the setting purification temperature (760 ℃ or higher) of organic exhaust gas, if temperature reaches, then directly passes through the combustion chamber; If temperature does not also reach purification temperature, then open burner, carry out assistant heating and make gas temperature reach the purification requirement; Burn within it; Remove VOC wherein with oxidation reaction, when high-temperature gas is through energy storage bed (going out the gas area) after the reaction, gas heat energy will import the former accumulation of heat material that has cooled off into; The heat that is high-temperature gas is stored, and gas is then with lower temperature discharging.Rotation along with the rotary valve rotor; Purge zone becomes air inlet area near lattice that go out the gas area; Purge zone becomes near lattice of air inlet area and the gas area; Desire is handled gas and is then imported this energy storage bed air inlet area preheating, and reaction back high-temperature gas energy then is stored in energy storage bed and goes out the gas area, accomplishes an operation cycle like this.Circulate with this, constantly higher when gas concentration, the heat of generation is enough to satisfy the preheating requirement of cold air next time; Make the direct preheating of waste gas of next time reach the purification requirement; System need not to open combustor and carried out assistant heating this moment, can accomplish the organic exhaust gas oxidation, purification, reached energy-saving effect.
In addition, when not opening combustor, when the temperature of energy storage bed still improved constantly, the unlatching of benefit air-cooler was mended cold, reduces bed temperature, guarantees security of operation.
But the problem that background technology exists is, the generation of used heat is far longer than the heat that recovery needs in order to preheating waste gas, and a large amount of like this waste gas heats are wasted.Therefore the present invention provides a kind of new organic exhaust gas to handle and heat energy recycle system and method.
Summary of the invention
A kind of organic exhaust gas and heat energy utilize system with receiving, and comprise an air-introduced machine, a heat accumulating type oxidation furnace that has combustor; One resistant to elevated temperatures bypath valve; One high temperature resistant dump air door, a thermal oil exchangers, a steam boiler; A monobromination lithium air-conditioning unit and a smoke stack emission device; Wherein the heat accumulating type oxidation furnace is connected through bypass line with bypath valve, thermal oil exchangers, steam boiler successively, and the heat accumulating type oxidation furnace is connected with the smoke stack emission device through main line, and a high temperature bypass dump air door is opened with chimney during overtemperature in the combustion chamber and is connected.
Its workflow is: will contain organic exhaust gas such as toluene, butanone, ethyl acetate and be incorporated in the heat accumulating type oxidation furnace equipment through an air-introduced machine, EGT is about 68 degree, under the combustor combustion preheater; Burning gradually, temperature also raises gradually in the oxidation furnace, more than 700 degree; Organic matter all is destroyed, and changes into carbon dioxide and steam, and discharges a large amount of heat energy; Oxidation furnace can kept under the situation that heat energy own needs, and combustor is just closed automatically, and the heat energy rice that oxidation furnace leans on organic exhaust gas self burning to discharge is fully kept; A heat part that produces is directly through the chimney exhaust, and heat another part of generation exchanges with thermal oil exchangers earlier through resistant to elevated temperatures bypath valve; The heating conduction oil, after the thermal oil exchangers heat exchange, hot flue-gas temperature is reduced to about 600 degree; Remove to drive a steam boiler then, flue-gas temperature drops to about 250 degree, and flue gas further cools off the back through the chimney exhaust; The steam that steam boiler produces removes to drive lithium bromide air-conditioning unit, is used for refrigeration or heating.If the oxidation furnace heat is overtemperature still, in case of emergency get into smoke stack emission through high temperature dump air door.
