Abstract
The invention relates to the field of organic waste gas combusting furnace, in particular to a two-level turbulence combustion waste gas environment-friendly processing furnace. The two-level turbulence combustion waste gas environment-friendly processing furnace is characterized in that a form of two-level combustion is used, and meanwhile organic waste gas is contacted with flame in a state of turbulence. The craft requirement that the organic waste gas stays for 0.7 second in a high temperature which is over 760 DEG C is met. The structure of the two-level turbulence combustion waste gas environment-friendly processing furnace comprises a preheating furnace and a combustion furnace. The preheating furnace is arranged under the combustion furnace. A flue of the preheating furnace is upward and is connected with a hearth of the combustion furnace. The furnace body of the combustion furnace is arranged horizontally. The flaming direction of a coke oven coal gas nozzle 1 is vertical to the air inlet direction of the preheating furnace, and the flaming direction of a coke oven coal gas nozzle 2 is vertical to the air outlet direction of the preheating furnace. A turbulence board is arranged between the flue of the preheating furnace and the hearth of the combustion furnace. Compared with the prior art, the two-level turbulence combustion waste gas environment-friendly processing furnace has the advantages that waste gas can be reliably combusted and decomposed completely and sufficiently, processing rate of the organic waste gas is improved, and the problem of pollution of the organic waste gas to the environment in a paint line is solved.
Description
Technical field
The present invention relates to organic waste gas furnace kiln field, particularly a kind of two-stage turbulent combustion waste gas environmental protection treatment stove.
Background technology
In colored steel is produced, paint line organic exhaust gas is mainly containing organic compounds such as toluene, dimethylbenzene, trimethylbenzene, ethanol, acetic acid, butyl ester, butanols, aromatic solvents, and these materials are as at will entered air, and environmental pollution is very large.Generally adopt regenerative furnace or the direct-fired kiln of one-level formula to carry out burning disposal to waste gas at present, more than 760 DEG C, continue 0.7 second at temperature, organic matter will decompose in chain rupture.Regenerative furnace adopts circulation accumulation of heat structure, and when a part of heat storage accumulation of heat, another part heat storage burns, and two parts timing conversion, in transfer process, some organic exhaust gas does not decompose completely, also can pollute., in flue gas, still there is the problem of Organic Pollution in the incomplete combustion of the direct-fired kiln of one-level formula.
Summary of the invention
The object of this invention is to provide a kind of two-stage turbulent combustion waste gas environmental protection treatment stove, overcome the deficiencies in the prior art, waste gas can reliably be burnt completely, reduce paint line organic exhaust gas to the pollution of environment.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of two-stage turbulent combustion waste gas environmental protection treatment stove, adopt the form of two-stage combustion simultaneously organic exhaust gas contact with flame under turbulent condition, meet the technological requirement that organic exhaust gas stops in high temperature 0.7 second more than 760 DEG C, make organic decomposition more complete, its structure comprises preheating furnace and incinerator, preheating furnace is arranged on the below of incinerator, and preheating furnace flue is upwards connected with incinerator burner hearth, and incinerator body is horizontally disposed with;
Coke-stove gas burner one flame direction in preheating furnace is vertical with preheating furnace air intake direction, the coke-stove gas burner two flame direction of incinerator is vertical with preheating furnace flue air-out direction, organic exhaust gas forms turbulent condition in flame, organic exhaust gas is warming up to 700-750 DEG C in preheating furnace, burns in-furnace temperature and controls at 750-850 DEG C.
For improving turbulent effect further, turbulence plate is provided with between described preheating furnace flue and incinerator burner hearth, turbulence plate is cylindrical shape orifice plate, the high-temp waste gas that preheating furnace flue can be made to enter incinerator enters incinerator burner hearth from 360 ° of directions with turbulent condition, and the flame sprayed with coke-stove gas burner two fully contacts.
Described incinerator flue is provided with heat recovery heat exchanger.
Compared with prior art, the invention has the beneficial effects as follows: make waste gas can reliably combustion decomposition cmpletely, improve VOCs treatment rate, solve the pollution problem of paint line organic exhaust gas to environment.
