Description
Technical field
The present invention relates to a kind of dual firing chamber, particularly a kind of for the incinerator dual firing chamber in refuse burning system, belong to technical field of environmental protection in chemical industry.
Background technology
During incineration treatment of garbage, dual firing chamber is the harmful substance of destroying further in flue gas, as bioxin, does not burn volatile matter etc., Shi bioxin, does not burn the harmful substances such as material and decomposes further, reaches environment protection emission requirement.And for hypoxgia in the middle part of traditional dual firing chamber, cause secondary flue gas not have Thorough combustion to fall, and fallen from smoke stack emission by heat-exchanging chamber, waste energy, contaminated environment.Burn further for realizing flue gas, current dual firing chamber's configuration secondary air feed system, but still it is still uneven to there is Secondary Air distribution, the dissatisfactory problem of combustion efficiency.
Summary of the invention
The present invention seeks to there is above-mentioned deficiency to overcome prior art, and provide a kind of for the incinerator dual firing chamber in refuse burning system, achieve the Secondary Air uniform distribution entering dual firing chamber, extend gas residence time, harmful substance in thorough combustion product gases, energy-conserving and environment-protective.
Technical scheme of the present invention is: comprise cylindrical shell, cone cover, smoke evacuation threeway; Cylindrical shell lower port is gas approach, and cylindrical shell upper port connects cone cover lower port, and cylindrical shell is outer around air loop duct, and air loop duct is provided with the combustion air inlet for connecting air blast, and air loop duct inner chamber is connected with cylinder lumen through airduct, nozzle assembly; Smoke evacuation threeway is provided with gas approach, flue gas dump mouth, exhanst gas outlet, and cone cover upper port connects the gas approach of smoke evacuation threeway.
Described airduct, nozzle assembly are multiple, and each nozzle assembly is around being arranged on barrel wall, and each airduct upper end and air loop duct intracavity inter-connection, each airduct lower end connects each nozzle assembly.
Described cylinder inboard wall is provided with the annular backup pad for each support nozzle assembly.
Described airduct is 90 degree of airducts.
Each nozzle assembly is all in tilted layout on barrel wall.
Described cylinder body outer wall is surrounded with support of duct, and air loop duct is loaded on support of duct.
Described barrel wall has more than one interface more than one, one interface two for external liquid waste spray gun for external burner.
Described cylindrical shell upper port connects cone cover lower port through flange three, and cylindrical shell lower port is welded with flange four; Between described flange three and cylindrical shell, between flange four and cylindrical shell, be evenly distributed with gusset.
Described barrel wall has the refractory casting bed of material, lightweight heat-proof to pour into a mould the bed of material from inside to outside successively, or barrel wall has fire brick layer, lightweight heat-proof to pour into a mould the bed of material from inside to outside successively; Described cone cover wall, smoke evacuation threeway wall have the refractory casting bed of material, lightweight heat-proof to pour into a mould the bed of material from inside to outside successively.
The straight tube two that described cone cover comprises cone cylinder, is welded in the straight tube one of cone cylinder upper end, is welded in cone cylinder lower end, straight tube one upper end is welded with flange one; Straight tube two lower end is welded with flange two.
The invention has the beneficial effects as follows: employing matches with 90 degree of airducts, angled some nozzle assemblies carry out uniform divided flows air feed; Airduct is arranged in combustion port slightly below, and cold wind not only increases the mixing of burner high ambient temperatures flue gas, and reduces the local temperature near burner; Adopt the double-deck furnace lining of castable refractory and light heat insulating castable, not only effectively avoid because the too high body of heater that makes of burning indoor temperature burns out, and the heat come out in combustion chamber when can take full advantage of burning carries out preheating to furnace lining, extends the service life of dual firing chamber; Exhanst gas outlet is designed to bending section, and sectional area is less than the sectional area of gas approach, extends the time of staying of flue gas in combustion chamber, Shi bioxin, do not burn the harmful substances such as material and thoroughly burn; Near exhanst gas outlet, devise dump mouth, prevent negative pressure and proterctive equipment; Each section of joint adopts flange connect, and dismounting is simple, greatly reduces dual firing chamber's maintenance cost.
