My partner and i. Introduction Daqing Petrochemical Company for a water gas plant surroundings separation flower, the company introduced a full set by the German Linde. The main raw material for the air, the primary products and services are oxygen and nitrogen, byproducts argon. The production ability, oxygen generation 10000m3 / h, nitrogen generation 30000m3 / h, installed in November 1985 put in operation. A air splitting up unit surroundings compressor is the air splitting up equipment for one of the most important, the health of the equipment directly related to the simple operation regarding air splitting up plants, surroundings separation plant in the whole play an essential role. To be able to ensure that they are trouble free, useful operation, minimize downtime and maintenance workload, it is necessary setting the surroundings intake air conditioning filter to cut back dust on the equipment damage. ge. A genuine design regarding air splitting up plants for the two surroundings filters, all with a shutter for the dry sort, used filtration cloth before and following the velocity regarding pressure control. Since the long service life, getting older equipment critically, backward technological innovation, in conjunction with insufficient precision filter, filtration effects, negative, a lot of dust getting inhaled surroundings compressor, the actual impeller on the scale, in a brief period of time up to air compressor shaft vibration, cause air compressor procedure cycles, repair and maintenance workload. Therefore, the surroundings compressor inlet air conditioning filter is regarding great significance to reform. Through many different filters available on the market a thorough investigation and study, finally selected the actual self-cleaning air conditioning filter. Second, problems Because the November 1985 generation date, this set of dry filter not conducted together with any reform, because running quite a while, and aging tools seriously. Initial pressure control system has failed, when the high pressure needed to staff the actual Drop dried hands together with. If the employee will not carefully monitored, entrance to the filtration pressure is extremely high happening of top air compressor spike jumping accident. Also dried with filter for the original particle size 20 ~ 30 m, blocking low accuracy, a lot of dust particles into the air compressor stream path through the filter cloth, collision leaves and air funnel, causing the surface regarding wear, and formed within the unit strong running, scaling effects of these surroundings movement, causing lower gadget efficiency so your “surge curve” move, and sometimes weaken the “balancing. ” The figure will be when the 2007 overhaul of the compressor blades on the carbon deposit taken pictures. Figure compressor cutting blades coke case 3, surroundings filters Classification and Selection Purification efficiency in line with the classification regarding air filters in line with the two countrywide standards, air conditioning filter categories, such as Dining table 1 [1, 2]. Dining table 1 shows the variety of initial resistance air conditioning filter. In practice, we need to consider the final weight of air conditioning filter. That “refers to rated flow as the filter particles, and also to increase and reach the mandatory resistance value. Generally 2 times the original resistance. ” [3] Dining table 2 shows the ultimate resistance air conditioning filter recommended value. According to the different filtration materials could be divided into: just one) fiber filters. Such as non-woven filtration cloth, filtration paper, glass fiber composite. 3) microporous filtration. Such as whole house water filtration systems, such filters usually are absolute filtration, micro-organisms on the filter applied. 3) particle filtration. Such as activated carbon filter, the actual filter from the activated carbon particles. Relative to the filtration level could be divided into single-stage filtering and multi-level blocking. Relative to the structure of Class: panel filtration, box box-type filtration, bag filters and cartridge filtration. Through researching the market, currently used to investigate the actual structure of the filter, after numerous domestic surroundings separation flower research, aware of the majority of new devices introduced on the sub-self-cleaning air conditioning filter. Regarding project construction and put in use Wuxi A Complete Limited as i live gas processing flower a ZKG-2500 Self-cleaning air conditioning filter. Items from the June 3, 2007 started out on-site civil construction, and on June 15 finished, 16 July an automobile air compressor surroundings separation formally put in use. Main technical variables in dining table 4. just one. Structure ZKG pneumatic self-cleaning air conditioning filter from the steel structure, filter package, and outlet tubes, computer control systems and self-cleaning gas supply program of several parts. Filtration system box in the upper chamber for the net, reduced half is divided into filter Pipe, includes: Venturi tube and the self-cleaning methods (including electromagnetic device), etc.. 3. Work just one) television air through the filter tube process, due to gravity, inertia proliferation, resistance to remain static and the combination effect of exposure, particles deposition, accumulation on the filter element, clean the airways venturi outlet after which to send. 3) self-cleaning process is dust on the air conditioning filter element, differential pressure with time or the manner set by the microcomputer automatic control, switch on the filtration cartridge cleaning, the particles wind the actual sediment particles into the atmosphere every plays merely a (6 unit) filtration cartridges in the self-cleaning process, enough time interval for the 60s, various other filter container filter is still in the normal doing work state, ZKG operate as typical. 3. Filtration system element structure Filter element for the 120 firm tubular filtration cartridge soon after fouling weight increased, when the resistance is too much, the actual pulse cleaning system commence, reverse the actual impact regarding air from the cartridge in the cartridge, cartridge on the overabundance dust were blown, followed down the actual resistance. Filter in this particular life of 1 to three years. a number of. Run benefit Self-cleaning filtration biggest advantage is the “zero maintenance”, longevity filter element, replacement filtration elements aren’t needed to stop. 5. Calibration Effects 2007 7 27 7 pm to at 7 o’clock on the August 30 entry on the air compressor filtration for 72h calibration. From the data in dining table 5 is seen, jogging resistance, maximum 161 Pennsylvania, the minimum amount is 129Pa. Average of 143 Pennsylvania, working well there. MIRE Conclusion Via this transformation to fix two major problems: just one) increase the filter size. Reduce the coke situation compressor blades could be more when the next maintenance precise comparative data. 3) address the necessity to manually drag and drop with the problem of dry, reducing the staff’s job intensity and increase the operation of the equipment safety factor.
