Abstract
The invention discloses an incineration method of organic mixed waste liquid containing salt. The method includes the steps of separation, incineration, waste heat recycling and tail gas purifying. In the step of incineration, an air blower and a burner are started so that the temperature of an incinerator can reach 992-998 DEG C; compressed air is introduced in waste liquid, and the introduction amount of the compressed air is controlled to be 0.6-0.7 L; the waste liquid is input into a waste liquid burner after being atomized, the temperature of a high-temperature combustion furnace is 1150-1900 DEG C, and the incineration time is 2-3 s. According to the incineration method of the organic mixed waste liquid containing the salt, the combustion time is short, the combustion efficiency is high, energy is saved, consumption is reduced, and the method can be continuously and stably used. High-temperature hot air is introduced into the incinerator burner so as to guarantee the efficient and stable combustion period of high-concentration organic waste liquid containing the salt. The high-concentration organic waste liquid containing the salt, or high-concentration organic waste water containing salt or waste oil is atomized and burnt by means of the compressed air, and the treatment effect is good.
Description
Technical field
The present invention relates to a kind of incinerating method of waste liquid, particularly relate to the incinerating method of the organic mixed waste liquor of saliferous, belong to field of waste liquid treatment.
Background technology
High concentration salty organic waste liquid is extensively present in new varieties agricultural chemicals and pharmaceutical manufacturing device, due to the material containing part contaminated environment, discharges again and can not directly discharge after needs process.
Solve the harm such as coking, slagging scorification, corrosion caused by low melting point salts such as alkali metal salts in organic waste liquid containing salt burning process.Process and method: evaporative crystallization---burning process is applied to the salt bearing liquid wastes process of being rich in low-boiling-point organic compound, can reach the effect of desalination and reduction auxiliary fuel consumption simultaneously.The backflow of evaporation raffinate continues evaporation.The phenol synthetic water of such as sodium chloride-containing produces the organic liquid waste steam containing organic concentration is very high, Na ion concentration is micro-in evaporation process.Organic volatility is higher than 99.00%, Na
+clearance reach 99.88%.Organic liquid waste steam directly enters fluidized bed incinerator and carries out burning disposal, can reach very high firing efficiency.Firing efficiency changes along with the change of organic concentration in incineration temperature, air quantity and steam.Incineration temperature is 850 DEG C, and air quantity is 20m
3during/h, 320ml organic liquid waste produces 200ml steam and disposable organic removal rate after carrying out burning disposal can reach 96.03% through pervaporation.
At present, the general burning disposal equipment adopted is connected successively with lower component: incinerator (comprising horizontal chamber furnace (oven), vertical heater I and vertical heater II successively)+fire tube waste heat boiler+air-introduced machine+scrubbing tower+chimney, its treatment process is: in walking to manage along the axial hydrojet of horizontal chamber furnace (oven), along vertical heater I bottom hydrojet, along vertical heater II top hydrojet, fire tube waste heat boiler employing flue gas, water walks the mode outside pipe, flue gas is introduced scrubbing tower and is carried out desulfurization by air-introduced machine, is then discharged by chimney.The feature of current this mode carries out multi-point liquid spraying burning at each position of incinerator, the treating capacity of each burner is less, all be less than 0.4t/h, throughput is less than 1.2t/h, and whole incinerator is direct current channel, makes the high-temperature flue gas time of staying less, simultaneously because incinerator each spot temperature difference is large, therefore vertical heater I and the usual ignition temperature of vertical heater II are lower than 1110 DEG C, and the time of staying is short, and organic matter reaction is not thorough.And water walks the mode outside pipe to adopt fire tube waste heat boiler heating surface to adopt flue gas to walk in pipe, make the easy blocking pipe of the flue gas containing inorganic salts, make the package unit steady and continuous cycle of operation be no more than 7 days; Gas consumption reaches 100m
3/ ton waste liquid, the energy recovery amount of waste liquid per ton is greater than 1.5 tons.
General, incineration technology of the prior art, the time of burning is long, incinerating method is complicated, and safety coefficient is not high, and operating efficiency is lower, for problem defect a series of in existing method for treating waste liquid, be badly in need of a kind of improving one's methods and meet the process requirements of society now.
Summary of the invention
The object of this invention is to provide the incinerating method of the organic mixed waste liquor of saliferous, to solve the still unsolved difficult problem of above-mentioned prior art.
The technical solution used in the present invention is: the incinerating method of the organic mixed waste liquor of saliferous, comprise separation, burning, waste heat recovery and tail gas clean-up step, it is characterized in that: described burn down step is for opening air blast and burner, incinerator temperature is made to reach 992-998 DEG C, in waste liquid, pass into compressed air, controlling compressed air intake is 0.6 ~ 0.7L, drops into waste-liquor burner after Waste liquid atomization, high-temp combustion furnace temperature is 1150-1900 DEG C, and the burning time is 2-3s.
Further, adjust the wind-force size of cooling air system in incinerator after described burn down step, controlling flue gas is 1110-1150 DEG C in the temperature of waste heat boiler import.
Further, described waste heat recovery is that the flue gas of high temperature incineration is carried out energy recovery by air preheater in heat recovery boiler.
Further, described tail gas clean-up step is be that the flue gas of 255 DEG C-260 DEG C drops into alkali lye and carries out desulfurization by temperature, and through except after look odor removal, discharges purifying smoke.
Further, described compressed-air actuated compression pressure is 0.4-0.6MPa.
Beneficial effect: the incinerating method of the organic mixed waste liquor of this saliferous of the present invention, burning time is short, and efficiency of combustion is high, energy-saving and cost-reducing, method can continuous and steady operation; High-temperature hot air is guided to incinerator burner by the present invention, thus ensures the combustion period that the organic salt bearing liquid wastes of high concentration is efficient, stable; The present invention uses compressed air spray burning high concentration salty organic waste liquid, the organic brine waste of high concentration or waste oil, and treatment effect is excellent.
