Abstract
The utility model discloses a dust collection system for dried adipic acid, which comprises a cyclone dust collector, a water dust scrubber, a washing water tank, an induced draft fan and a water suction pump. An air duct is arranged between a gas outlet of the cyclone dust collector and a gas inlet of the water dust scrubber, a water outlet at the bottom of the water dust scrubber is connected with a water inlet of the washing water tank, a gas outlet at the top of the water dust scrubber is connected with an extraction opening of the induced draft fan, a water outlet of the washing water tank is connected with a water suction opening of the water suction pump, and a spraying device for collecting dust is arranged in the air duct. The dust collection system realizes secondary recycle of the dust, tail gas is purified, exhausted and recycled and is not directly exhausted into a waste water treatment system, and the pressure of a sewage treatment system is reduced. Fine dust collection effects are achieved by means of slight modification and low investment for the dust collection system, a fluidized bed for the dried adipic acid has quite obvious tail gas and dust removing effects, and the dust content of tail gas emission is superior to nationally stipulated indexes.
Description
Technical field
The utility model belongs to chemical production technical field, relates in particular to a kind of brand-new dry adipic acid dust pelletizing system.
Background technology
In the dry adipic acid production process; Get into dry fluid bed through the centrifugation back and carry out drying; Dried adipic acid is from the fluid bed bottom discharge; Be used for cold wind gas phase discharge of dry hot blast and cooling, behind cyclonic separation and water film dedusting, discharge outdoor by the air-introduced machine extraction from the drying bed top.Exist the cyclone dust removal effect bad; Cause in the water dust scrubber adipic acid dust bigger, the moisture film that spray forms does not reach the effect of depositing dust, causes a large amount of dust to leak outside; Cause that dust exceeds standard in the dry adipic acid production period tail gas, bring environmental pollution and the infringement of health of human body.
The utility model content
The utility model provides the dry adipic acid dust pelletizing system that a kind of dedusting is thorough, reduce adipic acid tail gas environmental pollution in order to solve weak point of the prior art.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: dry adipic acid dust pelletizing system; Comprise cyclone dust collectors, water dust scrubber, washing tank, air-introduced machine and suction pump; Be provided with the air channel between the gas outlet of cyclone dust collectors and the air inlet of water dust scrubber, the delivery port of water dust scrubber bottom is connected with the water inlet of washing tank, and the exhaust outlet at water dust scrubber top is connected with the bleeding point of air-introduced machine; The delivery port of washing tank is connected with the pump mouth of suction pump, is provided with the spray equipment that is used for dedusting in the said air channel.
Said spray equipment comprises the nozzle of 8～12 Φ 4-6mm, is one group with 2 nozzles, and the two adjacent groups nozzle is 200-400mm along the airflow direction interval, and the spray direction of nozzle is identical with airflow direction, and the water inlet of nozzle is connected with the water inlet pipe that stretches out the air channel.
The water inlet of said washing tank is connected with the desalted water inlet pipe.
Be connected with return pipe between the delivery port of said suction pump and the water dust scrubber top, be connected with drainpipe on the return pipe.The washings that suction pump will wash in the tank can be transmitted back to the water dust scrubber recycle, also can directly recycle through drainpipe.
Adopt technique scheme; The key point of the utility model is in the air channel between the water dust scrubber, to have increased the nozzle that water sprays at cyclone dust collectors; Be equivalent to increase tail gas spray absorption plant, the type of nozzle, quantity, direction, operating pressure have determined the quality of spray effect.
The utility model has been realized the secondary recovery utilization of dust after the dust in the adipic acid waste gas is removed, not only realized the tail gas clean-up discharging, has also realized recycling, does not directly enter Waste Water Treatment, has reduced the pressure of sewage disposal system.The utility model is through forming good dust removing effects to the little transformation of dust pelletizing system, little input, and dry adipic acid fluid bed tail gas dust removal effect is very obvious, and the exhaust emissions dust content is superior to the national regulation index.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; The dry adipic acid dust pelletizing system of the utility model; Comprise cyclone dust collectors 1, water dust scrubber 4, washing tank 7, air-introduced machine 5 and suction pump 6; Be provided with air channel 2 between the air inlet of the gas outlet of cyclone dust collectors 1 and water dust scrubber 4, the delivery port of water dust scrubber 4 bottoms is connected with the water inlet of washing tank 7, and the exhaust outlet at water dust scrubber 4 tops is connected through exhaust column 8 with the bleeding point of air-introduced machine 5; The delivery port of washing tank 7 is connected with the pump mouth of suction pump 6, is provided with the spray equipment that is used for dedusting in the air channel 2.Spray equipment comprises the nozzle 3 of 8～12 Φ 4-6mm, is one group with 2 nozzles 3, and two adjacent groups nozzle 3 is 200-400mm along the airflow direction interval, and the spray direction of nozzle 3 is identical with airflow direction, and the water inlet of nozzle 3 is connected with the water inlet pipe 9 that stretches out air channel 2.The water inlet of washing tank 7 is connected with desalted water inlet pipe 10.Be connected with return pipe 11 between the delivery port of suction pump 6 and water dust scrubber 4 tops, be connected with drainpipe 12 on the return pipe 11.
The tail gas that drying bed contains dust gets into cyclone dust collectors 1; Get into water dust scrubber 4 through air channel 2 then; In air channel 2, add the nozzle 3 of 8-12 Φ 4-6mm, the desalted water that feeds water inlet pipe 9 supplies in the nozzle 3 sprays the tail gas from cyclone dust collectors 1.The hydraulic pressure that the installation of nozzle 3 provides according to the outside is selected the size and the type of nozzle bore, and the direction of installation is selected from cyclone dust collectors 1 to water dust scrubber 4 direction (airflow direction), and being generally 2 nozzles is one group, and 200-400mm is one group at interval.According to producing load, the come into operation quantity of nozzle 3 of decision is adjusted 3 directions of nozzle simultaneously, guarantees that the water smoke of nozzle 3 ejections forms water curtain one during use, and the dust in the barrier air gets into water curtain.Shower water in air channel 2 to dust moistening, washing is laggard goes in the water dust scrubber 4; Carry out second adsorption as the moisture film washings; Water dust scrubber 4 adsorbs dust once more through suction pump 6 transporting water simultaneously; Further reduce the dust content in the tail gas, the tail gas of removing behind the dust enters atmosphere through air-introduced machine 5 in the high-altitude.The spray washing water and the moisture film washings that contain the adipic acid dust are aggregated into washing tank 7, are transported to hexane diacid production system with suction pump 6 and recycle.The water inlet of washing tank 7 is connected with desalted water inlet pipe 10 and replenishes desalted water, and the washings that suction pump 6 will wash in the tank 7 can be transmitted back to water dust scrubber 4 recycles, also can directly recycle through drainpipe 10.The utility model drops into little, simple in structure, simple operation, and dust removing effects is very good, and dust emission is superior to the index of national regulation in the waste gas.
