Description

A kind of carbonization waste gas burner

Technical field

The utility model relates to a kind of carbon molecular sieve production equipment, especially a kind of carbonization waste gas burner.

Background technique

Carbon molecular sieve is a kind of new adsorbent, is a kind of excellent nonpolar carbon materials, is usually used in separating air richness Collect nitrogen.The basic production process of carbon molecular sieve includes mixing, extrusion forming, heated oxide, carbonization and plug-hole.Wherein, it is carbonized It is critical process.Carbonisation is that raw material is heated to cracking under nitrogen protection in brief, and exhaust gas has combustibility.It is existing Carbon molecular sieve production equipment be directly to light the exhaust gas of carbonisation, discharged after burning.But since exhaust gas includes a large amount of High carbon molecule, burning are not enough, and on the one hand can generate black smoke, make equipment carbon distribution, on the other hand unburned exhaust gas still has Certain toxicity, to environment nocuousness.Moreover, the heat that this equipment generates burning does not also utilize.Therefore, existing Carbon molecular sieve carbonization emission-control equipment there is a problem of that burning is insufficient, not environmentally friendly enough and energy utilization rate is lower.

Utility model content

The purpose of the utility model is to provide a kind of carbonization waste gas burners.The utility model have burning sufficiently, The environmentally protective and higher feature of energy utilization rate.

The technical solution of the utility model includes: a kind of carbonization waste gas burner, including sequentially connected mixing from bottom to up Room, combustion chamber and exhaust pipe；It is equipped with exhaust gas inlet and the first combustion adjuvant import below the mixing chamber, is equipped with above mixing chamber The mixed gas outlet of combustion chamber is protruded into, is equipped with igniter by mixed gas outlet side；It is equipped in the combustion chamber and is located at mixing Driven impeller above gas vent, mixing chamber is interior to be equipped with the mixing impeller coaxial with driven impeller.

In a kind of carbonization waste gas burner above-mentioned, the inner wall of the combustion chamber is equipped with thermal-collecting tube.

In a kind of carbonization waste gas burner above-mentioned, the exhaust pipe is horizontally disposed, and the lower section of exhaust pipe is equipped with mixing Tracheae, mixture pipe are equipped with and protrude into exhaust pipe pair port.

In a kind of carbonization waste gas burner above-mentioned, the driven impeller is identical with the blade arrangement of mixing impeller.

In a kind of carbonization waste gas burner above-mentioned, it is equipped with the second combustion adjuvant import below the combustion chamber, and the The height of two combustion adjuvant imports is lower than mixed gas outlet.

In a kind of carbonization waste gas burner above-mentioned, the igniter is electric spark igniter.

Compared with prior art, the utility model passes through the structure of driven impeller and mixing impeller, generates waste gas burning Thermal current band umbrella driven impeller and mixing impeller rotate, and then make the more fully mixed of exhaust gas and combustion adjuvant, fire it completely It burns.In this way, which the black smoke for generation of burning is reduced, equipment is not easy carbon distribution, while there will not be unburned exhaust gas direct emission, It is more environmentally protective.

Further, the heat that burning generates can be used for other equipment by thermal-collecting tube structure, effectively improve energy benefit With rate.

Further, unburnt exhaust gas is further reduced in exhaust combustion inner pipe using sub-fraction exhaust gas Amount.

Further, the blade arrangement of two impellers is identical, and airflow direction is also just identical, keeps whole flowing more logical Freely, while mixing impeller driving mixed gas flows to combustion chamber, it is ensured that safety.

Further, it is filled with combustion adjuvant in the combustion chamber, guarantees exhaust gas full combustion, and combustion adjuvant outlet is lower, Guarantee airflow direction, is conducive to driven impeller rotation.

To sum up, the utility model has the characteristics that abundant, the environmentally protective and energy utilization rate of burning is higher.

Specific embodiment

Below with reference to embodiment, the utility model is described in further detail, but be not intended as to the utility model limit according to According to.

Embodiment: a kind of carbonization waste gas burner, as shown in Figure 1, include from bottom to up sequentially connected mixing chamber 10, Combustion chamber 20 and exhaust pipe 30；Exhaust gas inlet 11 and the first combustion adjuvant import 12, mixing chamber are equipped with below the mixing chamber 10 10 tops are equipped with the mixed gas outlet 13 for protruding into combustion chamber 20, are equipped with igniter 21 by 13 side of mixed gas outlet；The combustion The driven impeller 22 for being equipped in room 20 and being located at 13 top of mixed gas outlet is burnt, is equipped in mixing chamber 10 coaxial with driven impeller 22 Mixing impeller 14.

The inner wall of the combustion chamber 20 is equipped with thermal-collecting tube 23.

The exhaust pipe 30 is horizontally disposed, and the lower section of exhaust pipe 30 is equipped with mixture pipe 31, and mixture pipe 31 is equipped with and protrudes into The secondary port of exhaust pipe 30.

The driven impeller 22 is identical with the blade arrangement of mixing impeller 14.

The second combustion adjuvant import 24 is equipped with below the combustion chamber 20, and the height of the second combustion adjuvant import 24 is lower than mixed Close gas vent 13.

The igniter 21 is electric spark igniter 21.

Working principle:

In the present apparatus, exhaust gas has 2 flow directions, most waste gas flow direction exhaust gas inlets 11, sub-fraction waste gas flow direction Mixture pipe 31；Combustion adjuvant, preferably oxygen have 3 flow directions, respectively the first combustion adjuvant import 12, the second combustion adjuvant import 24 With mixture pipe 31.Valve in gas flow duct is routine techniques, therefore is not repeated excessively.

The present apparatus is divided into original state and working condition.Original state is the state that device has just started, and two impellers are motionless. In the initial state, exhaust gas and combustion adjuvant are passed through as described above, with igniter 21 by the gas ignition in combustion chamber 20, then from The burned hot gas driving generated of movable vane wheel 22, mixing impeller 14 rotate simultaneously, and device enters working condition.In working condition Under, mixing impeller 14 by mixing chamber 10 exhaust gas and combustion adjuvant mix, exhaust gas and combustion adjuvant itself have flow direction, in conjunction with mixing The exhaust of impeller 14 flows to, therefore mixed gas flows to combustion chamber 20 from mixing chamber 10 always, will not flow backwards generation safety problem.

In combustion chamber 20, the hot gas of mixed gas burning, generation of burning drives driven impeller 22 to rotate, to make to mix The structure of impeller 14- driven impeller 22 constantly moves.The thermal-collecting tube 23 of 20 inner wall of combustion chamber can collect heat, thermal-collecting tube 23 General inner filling water, and be connected with other equipment.It is filled with combustion adjuvant in combustion chamber 20, guarantees exhaust gas full combustion, and And combustion adjuvant outlet is lower, guarantees airflow direction, is conducive to the rotation of driven impeller 22.

In exhaust pipe 30, the gas burning that mixture pipe 31 flows out, further burn the gas being discharged out of combustion chamber 20 Body is again provided with igniter in exhaust pipe.This step is divided into two kinds of situations: first is that combustion chamber 20 come out gas still have it is unburned Exhaust gas, then mixture pipe 31 can be burnt；Second is that the gas completely burned that combustion chamber 20 comes out, due to combustion adjuvant Amount be greater than theoretically complete combustion demand, therefore the exhaust gas of this sub-fraction also can full combustion in mixture pipe 31.
