Background technique
Come in, strict day by day both at home and abroad for environmental protection subject under discussion pay attention to day by day for the industrial gas emission standard, volatile organic matter (VOC
S) be one of present prevention and cure of air pollution emphasis.
The incineration method is for handling VOC
SWaste gas a kind of, under suitable incineration condition, VOC
SEliminating rate can reach more than 99%, products of combustion is different according to feed gas, common product is water, carbon dioxide, nitrogen oxide, oxysulfide etc.The incineration method generally can effectively be improved VOC contained in the waste gas
SAnd the foul smell problem, yet it quite expends fuel.Therefore, the design of burner should make VOC
SDirectly pass through flame with odorant, and enough combustion temperature, the waiting time and suitable current rate are arranged, to improve eliminating rate.
Heat accumulating type incinerator be for a kind of in order to pollutant device in the cremation treatment waste gas, simultaneously by the replacing of valve control airflow direction in the heat accumulating type incinerator, can making wherein, heat exchange unit produces accumulation of heat and heat release regeneration function.
Disclose a kind of three energy storage bed incinerator and usings method thereof in No. the 5th, 538,420, the U. S. Patent case, that is three energy storage beds (the the 1st, the 2nd and the 3rd) are arranged, and each energy storage bed still comprises a flushing and purifies end except that air inlet and outlet side.Three energy storage bed incinerators are because of many steps that feed flushing Purge gas (purge air) between accumulation of heat and preheating step, so need many energy storage beds.
Wherein also disclose a kind of rotary type heat accumulation incinerator as shown in Figure 1, it comprises a heating unit 10, organizes heat exchange unit 20, a changeover valve 30 and a driver element 40 more, this changeover valve 30 comprises a stator 31 and a rotor 32, this stator 31 is provided with a suction port 311, a relief opening 312 and flushing gas inlet 313, this heat exchange unit 20 is formed by many groups, be located between rotary valve 30 top, can change air inlet, the exhaust of each heat exchange unit or import the flushing Purge gas by this rotor 32.
In addition, U. S. Patent case the 6th, 203, disclose a kind of rotary type incinerator method of online smokeless heat baking (bake-out) continuously in 316B1 number, its purpose is to use an external source thermal source to heat the flushing Purge gas that is imported, by the rotation of changeover valve and the flushing gas of cooperation high temperature, one by one heat exchange unit is dried by the fire by the bottom is upwards hot, to solve the problem that above-mentioned high boiling point organic compound, mist of oil and burnt matter (tar) class material adhere to.
Existing known rotary type heat accumulation incinerator comprises at least one heater, at least two heat exchange units, a changeover valve (rotary valve), this changeover valve comprises a stator and a rotor, and stator is provided with a suction port, a relief opening and flushing Purge gas inlet.This heat exchange unit is formed by many groups, is located at the top of changeover valve, and its arrangement mode must cooperate the design of rotor.Fig. 2 is the schematic top plan view that the rotary type heat accumulation incinerator distributes through changeover valve rotor air-flow, for example shown in Figure 2, when this rotor upper end areas is divided into 10 (even number) conducting regions, then 10 (even number) heat exchange areas can be designed to radial every the unit, each heat exchange unit is communicated with via the conducting region of pipeline with the changeover valve rotor, by the revolution of changeover valve inner rotator, can change air inlet, the exhaust of each heat exchange unit or import the flushing Purge gas.
And Fig. 3 is rotary type heat accumulation incinerator or the changeover valve rotor of rotary type accumulation of heat heat exchanger and the schematic representation of air current flow.As shown in Figures 2 and 3, the waste gas that contains can enter via the suction port of stator via rotor (as the air inlet path A) and import heat exchange unit; Air-flow after incineration and accumulation of heat can be derived discharging through the relief opening of stator by rotor (as exhaust pathway B); And above-mentioned flushing Purge gas can enter via the inlet of stator, and imports heat exchange unit via rotor (as flushing purifying paths C).This heat exchange unit is formed by many groups, be located at the top of changeover valve, its arrangement mode must cooperate the design of rotor, for example shown in Figure 3, when this rotor upper end areas was divided into 10 conducting regions, then 10 heat exchange units can be designed to radially, and each heat exchange unit is communicated with via the conducting region of pipeline with the changeover valve rotor, by the revolution of changeover valve inner rotator, can change air inlet, the exhaust of each heat exchange unit or import flushing gas.
In the waste gas treatment process of above-mentioned rotary type heat accumulation incinerator or rotary type accumulation of heat heat exchanger, wherein this changeover valve is the effectiveness that must possess sealing, can be isolated fully with the waste gas of effectively institute's desire being handled, handle with incineration and the heat recovery of carrying out waste gas, avoid the cross pollution of undressed waste gas or escape, cause treatment of waste gas not exclusively or reduce heat recovery efficiency; Moreover, in waste gas incineration or heat exchange process process, the gas flow temperature that enters this changeover valve all is to keep at high temperature, when especially incinerator carries out elevated temperature heat baking (bake-out) (generally greater than more than 200 ℃, even more than 350 ℃), be that seal construction with this changeover valve also must bear high temperature, to keep the stability of sealing structure.
Be with, the present invention provides a kind of seal construction of changeover valve, and sealing structure is tool heat resistent property, abrasion resistance and chemical stability.
