Description
Technical field
The present invention relates to the incinerating method of a kind of incinerating method of waste liquid, more particularly to the organic mixed waste liquor of saliferous, belong to
Field of waste liquid treatment.
Background technology
High concentration salty organic waste liquid is widely present in new varieties agricultural chemicals and pharmaceutical manufacturing device, due to dirty containing part
The material of environment is contaminated, it is necessary to discharge and can not be directly discharged again after being handled.
Solve coking, slagging, the corrosion caused during organic waste liquid containing salt burning by the low melting point salt such as alkali metal salt
Deng harm.Process and method：Evaporative crystallization --- burning process is applied to the salt bearing liquid wastes rich in low-boiling-point organic compound and handled, energy
Desalination and the effect of reduction auxiliary fuel consumption are reached simultaneously.Raffinate backflow is evaporated to continue to evaporate.The phenol of such as sodium chloride-containing
Simulated wastewater is produced in evaporation process containing the organic liquid waste steam that organic matter is dense, Na ion concentration is micro.Organic matter
Volatility be higher than 99.00%, Na+Clearance reach 99.88%.Organic liquid waste steam is directly entered fluidized bed incinerator and entered
Row burning disposal, can reach very high firing efficiency.Firing efficiency is with organic concentration in incineration temperature, air quantity and steam
Change and change.Incineration temperature is 850 DEG C, and air quantity is 20m3During/h, 320ml organic liquid wastes produce 200ml through pervaporation and steamed
Vapour simultaneously carries out the disposable organic removal rate after burning disposal and can reach 96.03%.
At present, the general burning disposal equipment used is sequentially connected with lower component：Incinerator (successively including horizontal chamber furnace (oven),
Vertical heater I and vertical heater II)+fire tube waste heat boiler+air-introduced machine+scrubbing tower+chimney, its handling process is：Along horizontal chamber furnace (oven) axial direction
Hydrojet, along the bottom hydrojet of vertical heater I, along the top hydrojet of vertical heater II, fire tube waste heat boiler is walked using flue gas in pipe and water walks pipe
Flue gas is introduced scrubbing tower and carries out desulfurization by outer mode, air-introduced machine, is then discharged by chimney.The spy of current this mode
Point is to carry out multi-point liquid spraying burning at each position of incinerator, and the treating capacity of each burner is smaller, respectively less than 0.4t/h, total processing
Ability is less than 1.2t/h, and whole incinerator is direct current channel so that the high-temperature flue gas residence time is smaller, simultaneously because incinerator is each
Spot temperature difference is big, therefore vertical heater I and the usual ignition temperature of vertical heater II are less than 1110 DEG C, and the residence time is short, organic matter
Reaction is not thorough.And walked in pipe and by the way of water walked outside pipe, made containing inorganic using flue gas using fire tube waste heat boiler heating surface
The flue gas of salt easily blocks pipeline so that the package unit steady and continuous cycle of operation is no more than 7 days；Gas consumption reaches
100m3/ ton waste liquid, the energy recovery amount of waste liquid per ton is more than 1.5 tons.
General, incineration technology of the prior art, the burning time is long, and incinerating method is complicated, and safety coefficient is not high, work
It is less efficient, for a series of problem defect in existing method for treating waste liquid, it is badly in need of a kind of improved method to meet now
The process requirements of society.
The content of the invention
It is an object of the invention to provide the incinerating method of the organic mixed waste liquor of saliferous, not yet solved with solving above-mentioned prior art
Problem certainly.
The technical solution adopted by the present invention is：The incinerating method of the organic mixed waste liquor of saliferous, including separation, burning, waste heat
Reclaim and tail gas clean-up step, it is characterised in that：The burn down step reaches burning furnace temperature to open air blower and burner
To 500-1200 DEG C, compressed air is passed through into waste liquid, it is throwing after 0.6~0.7L, Waste liquid atomization to control compressed air intake
Enter waste-liquor burner, high-temp combustion furnace temperature is 1150-1900 DEG C, and the burning time is 12-27s.
Further, the wind-force size of cooling air system in incinerator is adjusted after the burn down step, control flue gas is remaining
The temperature of heat boiler import is 800 DEG C.
Further, the waste heat recovery is to enter the flue gas of high temperature incineration by air preheater in heat recovery boiler
Row energy recovery.
Further, the tail gas clean-up step is that the flue gas input alkali lye that temperature is 255 DEG C -260 DEG C is carried out into desulfurization,
And after except color odor removal, discharge purifying smoke.
Further, the compression pressure of the compressed air is 0.2-0.8MPa.
Beneficial effect：The incinerating method of the organic mixed waste liquor of this saliferous of the present invention, burning time is short, efficiency of combustion
High, energy-saving, method can be with continuous and steady operation；High-temperature hot air is guided to burning burner by the present invention, so as to ensure
The combustion period of the organic salt bearing liquid wastes of high concentration efficiently, stable；The present invention has with compressed air spray burning high concentration saliferous
The organic brine waste of machine waste liquid, high concentration or waste oil, treatment effect are excellent.
