Description
Technical field
The utility model relates to technical field of chemical, particularly relates to a kind of novel air condensing tower that the high-temperature fluorination hydrogen tail gas that contains the material dust is carried out purified treatment.
Background technology
The atmosphere condensing tower is applied to exhaust gas purification system in aluminum fluoride by dry process production, be the device of reacted hydrogen fluoride tail gas being realized condensation, purification, absorption.
Contain material dust, unreacted hydrogen fluoride gas in the reacted hydrogen fluoride tail gas, in the atmosphere condensing tower, behind the circulation fluid spray washing, remove the material dust in the tail gas, hydrogen fluoride gas is absorbed, reduce exhaust temperature simultaneously.Condensate liquid finally flow to atmosphere condensate liquid loop station.The exhaust gas body then carries out further purification separation through devices such as atmosphere condensation drop catcher, tail gas separators.Purified gas is extracted out by vavuum pump, and after being separated by steam-water separator, most of tail gas enters the middle absorbent clarifier, at last by middle absorbent tail gas funnel qualified discharge to atmosphere.Another part is by the recyclegas of pressure-regulating valve control as vavuum pump, with the process for stabilizing negative pressure.
The atmosphere condensing tower has played the effect of removing dust, absorbing hydrogen fluoride gas in the exhaust gas purification system of aluminum fluoride by dry process production, its application can reduce in the tail gas harmful substance to the pollution of atmospheric environment, makes it can qualified discharge after handling through follow-up purifier.
The atmosphere condensing tower is made of base, several graphite rolling rings, top cover, take-up device and circulation.The circulation fluid of high-temperature tail gas and spray usefulness enters from top cover, through several graphite rolling rings (column plate of each graphite rolling ring band, column plate is a deflection plate, some apertures distribute on the deflection plate), baffling step by step, at the bottom of tower, hydrogen fluoride gas is absorbed the material dust with circulating fluid, high-temperature tail gas is discharged from cat head after heat exchange cools simultaneously, enters follow-up purifier.
This atmosphere condensing tower is in running, exist following disadvantage: 1, because whole tail gas clean-up process system is a negative pressure system, pressure is about about-18KPa, high-temperature tail gas is when the internal flow of atmosphere condensing tower, in fact under suction function, be easy to " short circuit ", circulation fluid can not form effectively " water curtain ", thereby cause high-temperature tail gas and circulation fluid can not carry out fully effectively contacting, can not realize effective cooling and dedusting to tail gas, finally cause the obstruction of follow-up equipment, cause that system's negative pressure value is unusual, thereby influence the operation of whole production process system, increased personnel's cleaning equipment, number of times such as pipeline, and cleaning the time must stop production, consuming time longer, have a strong impact on output.2, owing in the atmosphere condensing tower, fail to realize effective cooling to high-temperature tail gas, and its follow-up pipeline all is a plastic material, high-temperature tail gas can cause very big infringement to pipeline, the pipeline of plastic material is deformed, even break, cause stopping production, the normal continuous service that influence is produced has also increased maintenance number of times and maintenance cost simultaneously.3, because the tail gas after purifying is extracted out by vavuum pump, the tail gas that does not obtain effective purified treatment can cause material to enter pump chamber, corrosion etc. to vaccum pump unit and have a strong impact on, shortened the service life of vavuum pump greatly, increased equipment cost.
Summary of the invention
The purpose of this utility model is to overcome the defective of above-mentioned prior art, provide a kind of and can realize effective spray, reach purification, cooling and dust removing effects, finally avoid follow-up equipment to stop up, raising equipment life cycle guarantees to produce successional novel air condensing tower.
The technical scheme that is adopted is for achieving the above object:
A kind of novel air condensing tower comprises base, several graphite rolling rings and be installed in column plate in the graphite rolling ring, and it is characterized in that: described column plate is circular sieve plate;
The sieve diameter of described sieve plate is 10～65mm, and each sieve plate is totally 4～18 row's sieve apertures, adds up to 32～90;
Described sieve plate layer and fault angle are installed, and its angle is 0～60 °.
Atmosphere condensing tower sieve plate layer of the present utility model and fault angle are installed, its angle is 0～60 °, and the sieve aperture of each layer sieve plate is staggered or the state that staggers, and can increase the contact area and the time of contact of gas and circulation fluid, thereby can realize effective spray, reach the effect of purification, dedusting, cooling.
Adopt atmosphere condensing tower of the present utility model can realize spray effectively to high-temperature tail gas, reach the effect of purification, dedusting, cooling, thereby can reduce in the tail gas harmful substance to the pollution of atmospheric environment, make it can qualified discharge after handling, reduce damage simultaneously follow-up system through follow-up purifier.Because high-temperature tail gas can access fully and effectively in atmosphere condensing tower inside with circulation fluid and contact, the dust that is mingled with in the tail gas can be with circulating fluid at the bottom of tower, finally enter in the atmosphere condensation pond of atmosphere condensate liquid loop station, avoided dust to enter follow-up equipment pipeline generation phenomenon of blocking, significantly reduced the cleaning work of equipment pipe, the stopping production of having avoided causing because of cleaning is lost, cleaning cycle extends to original 2～3 times, inventory during cleaning is few, clears up consuming timely to be reduced to original 1/50.After high-temperature tail gas is cooled, can the pipeline of follow-up plastic material not caused damage, what can guarantee to produce continues normal operation, has reduced maintenance cost.Dust in the tail gas, hydrogen fluoride gas have all obtained removing effectively, can not enter vavuum pump, and therefore the infringement to vavuum pump reduces, and has prolonged its service life, has reduced equipment cost.
Atmosphere condensing tower of the present utility model has improved the life cycle of equipment, has reduced the frequency of maintenance of equipment, has guaranteed the continuity of producing, and has realized environment has been protected in effective purification of the high-temperature fluorination hydrogen tail gas that contains the material dust.
