Description
Technical field
The present invention relates to a kind of heat accumulation incinerator of pressure accumulation Ex-all, relevant a kind of heat accumulation incinerator (Regenerative Thermal Oxidizer, RTO), by being provided with a heat accumulation incinerator, one waste gas main conduit line, one exhaust gas inlet valve group, one leads to the control valve group, one clean pneumatic transmission air pipe line, bucket is pressed in one storage, one gas control valve group and one provides Compressed Gas equipment, heat-accumulation combustion furnace gas stream flow direction can be made on the one hand the leakage pollution when switching airflow direction remove when switching energy storage bed, the unburned waste gas of another effect one energy storage bed does not have and leaks, the organic exhaust gas that is untreated in this energy storage bed is pushed the combustion chamber to be handled, the organic exhaust gas that prevents to be untreated is discharged when switching and after switching, avoid producing the pollution peak value of running, reach the stable function of utilizing, be applicable to and produce the industry that organic exhaust gas need reduce such as the production field of some particular industry, as the semiconductor industry, opto-electronics, chemical industry etc.
Background technology
Volatile organic matter (VolatileOrganicCompound, VOC) extensively be used in industrial circle, also be disposed to atmospheric environment with processing procedure, for example, organic exhaust gas with semiconductor and the discharging of photoelectricity industry processing procedure, (Isopropyl Alcohol C3H8O), acetone, cyclohexanone etc., easily causes environmental pollution to IPA.All there is strict empty dirty control test various countries for volatile organic matter, to safeguard the environmental protection and the common people's health; For example: Environmental Protection Administration has announced and has implemented semiconductor manufacturing industry air pollution control and discharge standard, for the reduction rate of semiconductor industry volatile organic waste gas mandatory requirement, and at least should be greater than 90%.
The processing method of organic exhaust gas is a lot, and it is one of important method that heat is incinerated the decomposition organic exhaust gas, and heat accumulation incinerator is wherein a kind of, and characteristic is that heat time efficient can be up to more than 90%.Wherein heat accumulation incinerator (RTO) can be double-tower type and disposes two energy storage beds (Regenerativebeds), and filling accumulation of heat material in the energy storage bed makes the volatile organic waste gas energy storage bed preheating (accumulation of heat this moment material disengages heat energy) of flowing through, and then enters the combustion chamber; At this moment, provide heat energy because the combustion chamber fuel nozzle produces flame, make the combustion chamber keep certain temperature (for example 850 ℃), in the holdup time of design, the contained VOCs composition of waste gas almost is completely oxidized to H2O and CO2 discharges then.
Fig. 1 is the structural representation of the tower heat accumulation incinerator of general traditional double (RTO); Heat accumulation incinerator 10a wherein mainly contains two groups of energy storage beds, and the first energy storage bed 12a is with the second energy storage bed 11a, combustion chamber 13a and the waste gas turnover pipeline that links to each other thereof and flow to control valve etc.; Wherein blower fan 28a, can have two kinds of patterns to enter among the 13a of combustion chamber and react to heat accumulation incinerator 10a inlet from source exhaust gas end pump drainage organic exhaust gas (VOCsLadenAir).First kind of pattern: organic exhaust gas enters pipeline by blower fan 28a inlet, enters the first energy storage bed 12a (flowing to control valve 22a and the 3rd second of this moment, to flow to control valve 23a be that OFF[closes] state) via first-class to control valve 21a respectively; The laggard organic exhaust gas of preheating enters in the combustion chamber and reacts; Organic exhaust gas provides a combustion flame 15a by fuel nozzle 14a in the 13a of combustion chamber, the ignition temperature of 13a inside, its combustion chamber can reach Celsius temperature more than 800 ℃, and organic exhaust gas is formed H2O and CO2 through oxidation reaction; Organic exhaust gas flows to control valve 24a via the second energy storage bed 11a, the 4th, is expelled in the atmosphere via chimney 351a; Wherein waste gas is by the second energy storage bed 11a time, and the second energy storage bed 11a is by the high-temp waste gas stream heating from the combustion chamber.Second kind of pattern: organic exhaust gas enters pipeline by blower fan 28a leading portion, flows to control valve 23a (it is the OFF state that at this moment first-class flows to control valve 24a to control valve 21a and the 4th) via the 3rd respectively and enters the second energy storage bed 11a; After passing through the second energy storage bed 11a preheating, organic exhaust gas provides a burning with flame 15a organic exhaust gas to be oxidized to H2O and CO2 by burner noz(zle) 14a in the 13a of combustion chamber, then by the first energy storage bed 12a, reach second and flow to control valve 22a discharging, the first energy storage bed 12a is heated by the high temperature gas flow of spontaneous combustion chamber.
Its above-mentioned first kind and second kind of pattern regularly circulate and do the air current flow direction and switch and keep the first energy storage bed 12a and the second energy storage bed 11a can keep high temperature in order to the preheating organic exhaust gas; Wherein the accumulation of heat material mostly is ceramic material and forms.Heat accumulation incinerator 10a commonly used, do when switching energy storage bed in double-tower type incinerator turnover valve in the operation period, can produce a particle emission peak that is equivalent to entrance concentration to chimney (floss hole), because incinerator can reach more than 98% to the destruction efficient of organic exhaust gas, and inlet air flow can directly be discharged to chimney when switching, 98% destroy efficient and estimate with this, this concentration is to cross 50 times high of exhaust in the incinerator place as can be known, and this causes the puzzlement of industrial circle always; Moreover, finish switching after, for being that the energy storage bed that charge heating is used will become the energy storage bed that the exhaust accumulation of heat is used originally, this moment, the former waste gas that is present in the energy storage bed did not incinerate resolution process because enter the combustion chamber as yet, still was untreated exhaust gas, to become pollution because of air-flow is oppositely blown out discharging by air-flow.The shortcoming of old friend's heat accumulation incinerator commonly used is that the air current flow direction of valve can produce a switch peak value that pollutes when switching, and the disappearance of its pollution makes it in practical occasion its disappearance be arranged.
In view of this, phase of the present invention can provide a kind of heat accumulation incinerator of pressure accumulation Ex-all, by being provided with clean pneumatic transmission air pipe line, storing up the Combination Design of pressing bucket, gas control valve group and Compressed Gas equipment being provided, the purpose of the pollution peak value in the time of can reducing heat accumulation incinerator device commonly used because of valve group switching air current flow direction, effectively to prevent the Organic Waste Gas Pollution atmosphere, and can provide the device requirement that is relevant to semiconductor industry or opto-electronics to use, be think of, the design team's system of grinding with great concentration, be the motivation person of wound that the present invention desires to grind.
