The exhaust gas treating system has simple structure and reasonable design, recovers aluminum fluoride particles from exhaust gases, improves the economic effect, meets the national standard of pollutant emission, meets the policy of energy conversation and emission reduction, reduces the pollution to the surrounding environment, ensures the continuous and steady process of production, and greatly improves the economic benefit and the social benefit.
Description
Technical field
The utility model relates to a kind of industrial waste gas treatment system, is specifically related to a kind of aluminum fluoride by dry process exhaust treatment system.
Background technology
At present, in aluminum fluoride by dry process is produced, general hydrogen fluoride gas and the aluminum hydroxide particles of adopting reacts in fluid bed, produce aluminum fluoride, produce a large amount of industrial waste gases simultaneously, the composition of this industrial waste gas is quite complicated, contain a large amount of steam, have neither part nor lot in the hydrogen fluoride of reaction, ocratation, sour gas such as sulfur trioxide, simultaneously also with a large amount of aluminum fluorides and aluminum hydroxide particles, and EGT up to 400 ℃ about, if not treated direct discharging, meeting severe contamination surrounding enviroment, this waste gas utilizes fully simultaneously, causes the very big wasting of resources.
The utility model content
The utility model is in order to solve weak point of the prior art, the aluminum fluoride by dry process exhaust treatment system is provided, it to the industrial waste gas that produces in the aluminum fluoride by dry process production lower the temperature, a series of processing such as removal of impurities, purification, recycle utility, " clean " exhaust gas is entered atmosphere.
For solving the problems of the technologies described above, aluminum fluoride by dry process exhaust treatment system of the present utility model, described system comprises dust arrester, condensing unit, gas-liquid separation device and the purifier that connects by pipeline successively, also comprises in the described system runner and takes out negative pressure device.
Described dust arrester is a rotoclone collector, described condensing unit is the atmosphere condensing tower, and described gas-liquid separation device is a drop catcher, and described purifier is a purifying column, the described negative pressure device of taking out is a vavuum pump, and the suction opeing of vavuum pump is connected by pipeline with the purifying column gas outlet.
The air outlet of described vavuum pump is connected with the middle absorbent device with separator successively by pipeline.
Described rotoclone collector is made up of one-level rotoclone collector and secondary rotoclone collector.
Described purifying column is made up of first class purification tower and secondary purification tower.
After adopting said structure, under the effect of taking out negative pressure device, dust arrester reclaims the solid particle of following in the waste gas (most of is the aluminum fluoride finished product), condensing unit drops to the normal temperature state with high-temp waste gas, gas-liquid separation device absorbs the steam in the waste gas, purifier absorbs acid gas purifyings such as the hydrogen fluoride in the middle of the waste gas, ocratation, sulfur trioxide, in case negative pressure device is taken out in the sour gas corrosion; Dust arrester is a rotoclone collector, and condensing unit is the atmosphere condensing tower, and gas-liquid separation device is a drop catcher, and purifier is a purifying column, and taking out negative pressure device is vavuum pump, adopts such equipment, and cost is low, durable in use, high efficiency; Rotoclone collector, atmosphere condensing tower, drop catcher, purifying column, vavuum pump connect by pipeline successively, this steps such as dedusting, condensation, gas-liquid separation, purification, the better effects if of carrying out successively; Separator and middle absorbent device again to be about to enter waste gas in the middle of the atmosphere do last separate, purified treatment, make waste gas thoroughly meet the requirement of energy-saving and emission-reduction; Two stage cyclone dust-precipitator and two-step purification tower are set, make and collect solid particle and reclaim sour gas better effects if, more thorough; The utility model is simple in structure, reasonable in design, reclaims aluminum fluoride particle in the waste gas, has improved economic benefit, the satisfied country standard that discharges pollutants meets the energy-saving and emission-reduction policy, has reduced the pollution to surrounding enviroment, guarantee to produce the carrying out of continous-stable, economic benefit, social benefit improve greatly.
