The characteristic of VOCs
According to the boiling point characteristic of emission gases, can classify as high boiling VOCs (boiling point is greater than 150 ℃), general boiling point organic compound (boiling point is more than 30 ℃, below 150 ℃) and room temperature are the organic compound that gas exists.
And can divide into smelly, malicious and general VOCs according to the chemical property of emission gases.It also causes in various degree harm to environment.
The general processing method of VOCs
Hybrid treatment system: runner inspissator+regeneration regenerative oxidation stove (Regenerat iveTO; RTO)
Concentration runner system: this system divides adsorption and desorption, cooling Three regions, and system adsorbs the VOCs in the waste gas and the VOCs after the absorption is carried out the high temperature desorption, and the runner behind the desorption enters the cooling zone, prepares against follow-up absorption after the cooling.Periodic duty, Zhou Er renews.
Incinerator system: to carrying out 732 ℃ of cracking of high temperature through runner desorption VOCs out, the composition after the cracking respectively with O
2Reaction generates carbon dioxide and water vapour.
Heat-exchange system: incinerator gas and the gas behind the desorption out carries out heat exchange, makes the gas temperature that will enter oxidation furnace reach suitable temperature, thereby reduces the oxidation furnace combustion fuel.
Each state all endeavouring to research and develop VOCs treatment technology of new generation, especially payes attention to the VOCs incineration technology especially.This incineration treatment technology carries out heated oxide, cracking to VOCs exactly, and hydrocarbon is converted into carbon dioxide (CO
2) and water (H
2O) typical process.This process is that the processing procedure EGT is raise to interrupt hydrocarbon key, and produces carbon dioxide (CO
2) and water (H
2O).The generation of this process also produces exothermic reaction.The thermal source demand of incinerator mainly is to add hot-air to the needed heat of organic solvent cracking, and organic solvent also can provide partial heat energy in cracking, reduces the demand to fuel.Burn burner hearth and should remain on 800-850 ℃ and allow and in burner hearth, be detained oxidized, cracking of a period of time, during this period of time should be less than 2 seconds.VOC
SAfter carrying out heated oxide, cracking, produce carbon dioxide (CO
2) and water (H
2O) be discharged into atmosphere, environment is not polluted, still, still with heat, this just needs a good combustion system and heat recovery equipment, makes emission gases reach state-set standard, reduces consumption to the energy, eliminates the pollution to ecological environment.
At present, two-tower type, the positive extensive use of three-tower type VOCs incinerator.The complex structure of two-tower type, three-tower type incinerator, bulky, VOCs heated oxide, cleavage rate 95-99%.These incinerators are designed with regenerator, the cellular ceramic structure heat storage tank of the inner filling of regenerator, and heat recovery efficiency can reach about 93% (± 2%).The heat storage tank segmentation is absorbed heat, heat release, blowing, is blowing down section, and air inlet duct and the switching of air discharge duct heat reach the purpose of recuperation of heat.But the machine that the opens stage of two-tower type, three-tower type VOCs incinerator needs preheating, and the burned machine of ceramic heat-storing groove is heated gradually to operating temperature, before heated oxide is processed, needs to consume a large amount of fuel at VOCs.The intensification of absorbing heat of the heat storage tank of VOCs by heat release, after burning hearth combustion, the gas of high temperature passes through the heat storage tank heat release again, the heating heat-storing material.Utilize heat absorption, the exothermic process of ceramic heat-storing material to carry out waste heat recovery, although reduced part of fuel consumption, waste heat recovery efficient is low.Use a large amount of porcelain heat-storing materials, make body of heater bulky, increased incinerator construction cost.Because the cellular loose structure of heat storage tank, pipeline is elongated, VOCs turbulent flow type air-flow turns round more in burner hearth, windage is large, air-flow velocity is low, easily is detained remaining unburned VOCs material, causes pipe blocking, need at any time removable parts heat storage tank and increase blowing blower fan, also increased construction cost and maintenance cost.These costs that become current two-tower type, three-tower type VOCs incinerator are high, the principal element of complex management, Frequent Troubles, maintenance difficult.
In order to improve VOCs heated oxide, lysis efficiency, reduce the consumption of fuel, reduce burning construction cost, we design the non-phase transformation super heat-conductive pipe of seriation L-type heat reclamation type VOC according to the basic principle of " spiral of Archimedes "
SIncinerator, the combustion chamber of incinerator are designed to ceramic spiral of Archimedes burner hearth, and the entrance angle of air outlet and burner hearth is 13.5 degree.Be concentrated, after the VOCs behind the desorption enters ceramic spiral of Archimedes burner hearth, form spiral air flow, fully mix with combustor flame, completing combustion.Spiral air flow time of staying in burner hearth is burned furnace superintendent than two-tower type, three-tower type VOCs, can not produce residual gas and residue, has both reduced the consumption of fuel, and efficiency of combustion is significantly improved.The non-phase transformation super heat-conductive pipe of seriation L-type heat reclamation type VOC
SIncinerator makes VOCs at the first combustor burning phase, near whole oxidations, cracking after adopting new combustion system and process, cleavage rate reaches 96-98%, at the second combustor combustion phases, continue oxidation, cracking, cleavage rate reaches more than the 99-99.5%.The non-phase transformation super heat-conductive pipe of seriation L-type heat reclamation type VOC
SIncinerator is higher than the cleavage rate of the two-tower type that generally adopts in the world now, three-tower type VOCs incinerator, does not need to install cellular ceramic structure heat storage tank, and it is little more than 30% that volume is wanted, and construction cost reduces 35-40%.Also having reduced mounting cost and maintenance cost, is the high-efficiency environment friendly product of energy-saving and emission-reduction, has represented development trend and the direction of VOCs incinerator of new generation.
