Description
Technical field
The utility model relates to a kind for the treatment of apparatus, especially a kind of harmless treatment of refuse and recycling device that refuses such as industrial dangerous waste, clinical waste, domestic waste, municipal sludge and biological straw carry out pyrolysis and burning that be used for.
Background technology
At present in the burning disposal and application technology as the second resource of arbitrary class refuses such as the industrial dangerous waste of domestic and international application, clinical waste, domestic waste, municipal sludge, biological straw, mostly adopt the technology such as fluidized bed incinerator, stoker fired grate formula incinerator, rotary kiln type incinerator, incinerator for thermal decomposition of above-mentioned refuse being carried out direct burning disposal.Above-mentioned incineration technology ubiquity investment is high, operating cost is high, control problems such as difficulty is big.
Summary of the invention
The technical problem that the utility model solved is the defective that overcomes prior art, a kind of wide accommodation is provided, disposal ability is strong, safe and reliable, operating cost is low, every economic technology and environmental protection index advanced person, be used for arbitrary class refuses such as industrial dangerous waste, clinical waste, domestic waste, municipal sludge, biological straw are carried out the harmless treatment of refuse of pyrolysis and burning and the device of recycling, can carry out the pyrolysis of appropriateness according to the difference of refuse.Wherein said waste pyrolysis and incinerating and treating device mainly comprise: high-temperature flue gas pyrolysis rotary kiln and incinerator.
Send in succession in the feed end of rotary kiln by the requirement of required pyrolysis processing amount by the refuse that the hydraulic pressure material-pulling device will enter in the storage bin(hopper); The refuse of going into behind the kiln moves to the rotary kiln discharge end under effect with conditions such as angle of declinations is stirred in revolution uniformly.Part by the high-temperature flue gas that incinerator produced enters in the discharge end of rotary kiln by the high-temperature flue gas pipeline under the effect of rotary kiln negative pressure, and the flow direction of high-temperature flue gas in kiln is opposite with the direction of motion of refuse.Refuse in the rotary kiln carries out pyrolysis under the effect of high-temperature flue gas, its pyrolysis gas confuses flue gas and flows to the feed end of rotary kiln, sends in the calandria pyrolysis smoke sub-cylinder of incinerator by the pyrolysis smoke pipeline under the effect of pyrolysis smoke blower fan and goes into the stove burning disposal.Decorating film matter behind the waste pyrolysis is sent outside the kiln by sealing cooling output device.The pyrolysis smoke pipeline is fixedlyed connected with the calandria pyrolysis smoke sub-cylinder of incinerator.High-temperature flue gas pyrolysis rotary kiln should adopt heat proof material, and takes measures such as corrosion-resistant thermal insulation sealing.The rotating speed that is provided with temperature sensor, pressure sensor, rotary kiln in the rotary kiln is adjustable.
The high-temperature flue gas that is taken from incinerator dual firing chamber upper end is sent in the discharge end of high-temperature flue gas pyrolysis rotary kiln by the high-temperature flue gas pipeline under the effect of rotary kiln negative pressure.The high-temperature flue gas of going into kiln when the rotary kiln feed end flows to kiln in refuse carry out pyrolysis, its pyrolysis gas confuses behind the feed end of flue gas flow direction rotary kiln under the effect of pyrolysis smoke blower fan to send in the calandria pyrolysis smoke sub-cylinder of incinerator by the pyrolysis smoke pipeline goes into the stove burning disposal.Regulate and control high-temperature flue gas pyrolysis rotary kiln temperature and pressure by the rotating speed of transferring the pyrolysis smoke blower fan, and then realize the purpose of control waste pyrolysis treating capacity.The high-temperature flue gas interface of incinerator dual firing chamber is connected with the discharge end of pyrolysis rotary kiln by high temperature smoke pipe line tracheae line.Because the not direct incinerating waste material of this incinerator, but incinerating combustion value is higher and uniform shaped fuel.An elegance hot blast of its stove, the heat-insulating combustion chamber is all adopted in the part of dual firing chamber in a combustion chamber, therefore can guarantee the stable operation of this stove.The pyrolysis smoke of going into stove by calandria pyrolysis smoke sub-cylinder in the burning disposal process through whole high temperature section of a combustion chamber and dual firing chamber, because of its at high-temperature region time of staying long enough, can guarantee the abundant decomposition of harmful substance.For guaranteeing the abundant after-flame of combustible volatile, this stove has been arranged high-voltage secondary wind.This stove also is provided with auxiliary facilities such as start-up burner, waste heat boiler, air preheater, fire grate device, temperature sensor, pressure sensor.High-temperature flue gas pipeline and pyrolysis smoke pipeline all should adopt corresponding heat proof material and take the corrosion-resistant thermal insulation measure.
Decorating film matter behind the waste pyrolysis through magnetic separation, is picked up choosing by sealing cooling output device, is squeezed into shaped fuel after the processes such as screening.Wherein the sealing function of sealing cooling output device is isolated with oxygen, material takes place before preventing to lower the temperature fire burns; Effect after the cooling is to end pyrolysis, and for follow-up magnetic separation, pick up technical process such as choosing, screening suitable processing temperature environmental condition be provided; Magnetic separation and the effect of picking up choosing are material recycles and remove inorganic matter, thus improve shaped fuel than part calorific value, the effect of screening is a molding effect of guaranteeing fuel.For compensating special regional refuse calorific value deficiency, guarantee the heat capacity of incinerator, also can when the processing shaped fuel, allocate a certain proportion of exotic fuels into.
Owing to adopt above-mentioned technical scheme, the utlity model has following beneficial effect:
Can adapt to all kinds of different wastes processing, can be at different condition and regional set handling equipment, treatment scale can be greatly, can be little; Form technology maturation reliable, be convenient to control; Can realize advanced economic technology and environmental protection index.
