Description
Technical field
The utility model relates to the exhaust-gas treatment field, specifically, is that a kind of organic exhaust gas is from preheating catalytic burning device.
Background technology
At present; All can produce a certain amount of organic exhaust gas in industries such as chemical industry, printing and dyeing, oil, agricultural chemicals, metallurgy, application, chemical vapour deposition (CVD) plated films; These organic exhaust gas complicated components have significant damage to health; Fully just do not enter in the atmosphere if purify, can cause persistence to pollute, be difficult to administer environment.Therefore, just allow to be discharged in the environment after need organic exhaust gas being purified fully.
At present to adopt pyrolytic be the most also to be effective treatment craft to the organic exhaust gas burning process.In general organic exhaust gas just can decompose through certain hour at 800 ℃ fully fully; When incinerator non-uniform temperature, exhausted air quantity will cause organic matter to decompose not exclusively when greatly perhaps exhaust gas concentration is too high, be discharged in the atmosphere environment and human body are still had very big harm.If adopt the incinerator of normal conventional to handle, treatment effect is incomplete on the one hand, and producing a large amount of heat when organic exhaust gas decomposes does not on the other hand have fully effectively to utilize the waste that causes the energy.
The utility model content
Have the defective of decomposing incomplete and thermal waste to existing single incinerator, the purpose of the utility model is to provide a kind of organic exhaust gas complete decomposition, energy recovery fully from preheating catalytic burning device.
The purpose of the utility model is achieved through following technical scheme, and a kind of organic exhaust gas comprises an incinerator from preheating catalytic burning device; The top of said incinerator is provided with air inlet; The bottom of incinerator is provided with the gas outlet, and the sidewall of incinerator is equipped with the burning device, and the front end of said incinerator is provided with a catalyst chamber; Said catalyst chamber is provided with air inlet and gas outlet, and the gas outlet of catalyst chamber is communicated with the air inlet of incinerator.
The further technical scheme of the utility model is, the periphery of said catalyst chamber is provided with preliminary heating zone, and said preliminary heating zone is provided with high temperature air inlet and low temperature gas outlet, and the high temperature air inlet of preliminary heating zone is communicated with the gas outlet of incinerator.
In the said catalyst chamber catalyst is housed.
The filler that delays gas flow is housed in the said preliminary heating zone.
The said filler that delays gas flow is a Pall ring.
Said catalyst is carrier with the natural mordenite zeolite, and active component is combined by manganese oxide, chromium oxide, titanium oxide.
Purge gas after the process incinerator decomposes fully contains a large amount of heat; Directly discharging can cause energy waste; High-temperature gas after this device will purify is introduced the high temperature air inlet of the peripheral preliminary heating zone of catalyst chamber through the gas outlet of incinerator; The packing material Pall ring that is provided with in the preliminary heating zone has increased resistance and stroke that high-temperature gas is advanced in preliminary heating zone; Increase the time of staying of high-temperature gas in preliminary heating zone; Make the organic exhaust gas that gets into catalyst chamber have time enough to be preheating to catalytic temperature, wherein a part of organic exhaust gas is decomposed through catalyst at this, the purification pressure of rear end incinerator when having shared excessive or excessive concentration because of the organic exhaust gas amount; That decomposes in the catalyst chamber gets into incinerator with undecomposed organic exhaust gas from catalyst chamber low side gas outlet, the release of the high-temperature gas passes heat in the preliminary heating zone is after the cryopumping mouth discharge of preliminary heating zone lower end.
The utility model and existing burned waste gas apparatus in comparison have following beneficial effect:
(1) from the preheating design hot gas after purifying is carried out effective heat energy recycle, energy-saving effect is remarkable, and through actual measurement, energy efficient is more than 30%;
(2) incinerator Front-end Design catalyst chamber has effectively been shared the pressure of rear end incinerator cleaning organic waste gas, when handling the organic exhaust gas large-minded, that concentration is high, also can accomplish to decompose fully, and through actual measurement, the purifying rate of organic exhaust gas can reach 99.99%.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
As shown in Figure 1, a kind of organic exhaust gas that the utility model provided comprises an incinerator 5 from the preheating incinerator; The top of said incinerator 5 is provided with air inlet C, and the bottom of incinerator 5 is provided with gas outlet D, and the sidewall 5 of incinerator is equipped with burner 6; The bottom of incinerator 5 is provided with dust arrester 7, and the bottom of dust arrester 7 has ash hole G, and the front end of incinerator 5 is provided with a catalyst chamber 1; Air inlet A is established at the top of catalyst chamber 1, the bottom sets out gas port B; The gas source pipe of organic exhaust gas connects the air inlet A at catalyst chamber 1 top, and catalyst 3 is equipped with in catalyst chamber 1 inside, and catalyst 3 is a carrier with the natural mordenite zeolite; Active component is combined by manganese oxide, chromium oxide, titanium oxide; The gas outlet B of catalyst chamber 1 is communicated with through pipeline with the air inlet C of incinerator 5, and the periphery of catalyst chamber 1 is provided with preliminary heating zone 2, and said preliminary heating zone 2 is provided with high-temperature gas import E and cryogenic gas outlet F; The high-temperature gas import E of preliminary heating zone 2 is communicated with through pipeline and air-introduced machine 8 with the gas outlet D of incinerator 5, and the filler Pall ring 4 that delays gas flow is set in the preliminary heating zone 2.
