Abstract
The invention discloses an incineration method for saliferous organic mixed effluent. The incineration method for the saliferous organic mixed effluent comprises the steps of separation, incineration, waste heat recycling and tail gas purification. According to the incineration step, an air blower and a combustor are started, the temperature of an incineration furnace reaches 990-1000 DEG C, compressed air is introduced into the effluent, the introduction amount of the compressed air is controlled to be 0.5-0.8 L, the effluent is input into the effluent combustor after being atomized, the temperature of a high-temperature combustion furnace is 1150-2000 DEG C, and the incineration time is 2-3 s. The incineration method for the saliferous organic mixed effluent is short in combustion time, is high in combustion efficiency, saves energy, lowers consumption, and can be continuously and stably carried out. According to the incineration method for the saliferous organic mixed effluent, high-temperature air is introduced into the combustor of the incineration furnace, and therefore the efficient and stable combustion period of the high-concentration saliferous organic mixed effluent is guaranteed. The incineration method adopts the compressed air to atomize and combust the high-concentration saliferous organic mixed effluent, high-concentration organic saliferous waste water or waste oil, and is good in treatment effect.
Description
Technical field
The present invention relates to a kind of incinerating method of waste liquid, relate in particular to the incinerating method of the organic mixed waste liquor of a kind of saliferous, belong to liquid waste processing field.
Background technology
High concentration salty organic waste liquid is extensively present in new varieties agricultural chemicals and pharmaceutical manufacturing device, due to the material that contains part contaminated environment, after need to processing again discharge and can not directly discharge.
Solve the harm such as the coking that caused by low melting point salts such as alkali metal salts in organic waste liquid containing salt burning process, slagging scorification, corrosion.Process and method: evaporative crystallization---burning process is applied to the salt bearing liquid wastes processing of being rich in low-boiling-point organic compound, can reach the effect of desalination and reduction auxiliary fuel consumption simultaneously.Evaporation raffinate refluxes and continues evaporation.The phenol synthetic water of for example 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 variation of organic concentration in incineration temperature, air quantity and steam.Incineration temperature is 850 ℃, and air quantity is 20m
3when/h, 320ml organic liquid waste produces 200ml steam and the disposable organic removal rate that carries out after burning disposal can reach 96.03% through pervaporation.
At present, the general burning disposal equipment adopting is to be connected successively with lower member: incinerator (comprising successively horizontal chamber furnace (oven), vertical heater I and vertical heater II)+fire tube waste heat boiler+air-introduced machine+scrubbing tower+chimney, its treatment process is: along the axial hydrojet of horizontal chamber furnace (oven), along vertical heater I bottom hydrojet, adopt flue gas to walk in pipe and water is walked the mode outside pipe along vertical heater II top hydrojet, fire tube waste heat boiler, air-introduced machine is introduced scrubbing tower by flue gas and is carried out desulfurization, then discharges by chimney.The feature of current this mode is to carry out multi-point liquid spraying burning at the 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 the each position of incinerator temperature difference is large, therefore vertical heater I and the common ignition temperature of vertical heater II are lower than 1100 ℃, and the time of staying is short, organic matter reaction is not thorough.And adopt fire tube waste heat boiler heating surface to adopt flue gas to walk in pipe and water is walked the mode outside pipe, and make the easy blocking pipe of flue gas that contains inorganic salts, make the package unit steady and continuous cycle of operation be no more than 7 days; Gas consumption reaches 100 m
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 burning time is long, incinerating method complexity, safety coefficient is not high, and operating efficiency is lower, for a series of problem defect 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 a kind of saliferous, to solve a 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 a kind 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, make incinerator temperature reach 990-1000 ℃, in waste liquid, pass into compressed air, controlling compressed air intake is 0.5～0.8L, drops into waste-liquor burner after Waste liquid atomization, high-temp combustion furnace temperature is 1150-2000 ℃, 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 1100-1150 ℃ 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 to energy recovery by air preheater in heat recovery boiler.
Further, the flue gas that described tail gas clean-up step is is 250 ℃-260 ℃ by temperature drops into alkali lye and carries out desulfurization, and through except after look odor removal, discharges purifying smoke.
Further, described compressed-air actuated compression pressure is 0.4-0.5MPa.
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, thereby guarantee efficient, the stable combustion period of the organic salt bearing liquid wastes of high concentration; 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 good.
