Description
Technical Field
The utility model belongs to the technical field of industrial dust removal equipment, and particularly relates to an adjustable pleated filter bag frame and a use method thereof.
Background
Bag dust collection is gradually developed into a mature dust collection and flue gas purification technology with wide applicability and good economy. The bag type dust collector is a dry type high-efficiency dust filtering device which is made of porous fiber materials and is used for collecting dust particles in dust-containing airflow, and the dry type high-efficiency dust filtering device is suitable for collecting fine, dry and non-fibrous dust. The filter bag is generally made of woven filter cloth or non-woven felt, and most of the filter bags are nonwoven needled felt filter cloth at present. After the dust-containing gas enters the bag type dust collector, coarse dust particles can be settled to the ash bucket under the action of gravity, and finer dust is trapped by the filter bag when passing through the filter material along with the airflow, so that the gas is purified.
The conventional dust-removing filter bag is generally in a straight cylinder shape, the surface of the filter bag is relatively flat, and the conventional dust-removing filter bag has the defects of small filtering area, poor filtering effect and the like. On the one hand, when the dust-containing air flow speed and dust abrasion are relatively strong, the filter bag is directly abraded, and the service life of the filter bag is shortened, so that the air flow speed must be strictly and properly controlled. On the other hand, in the filtering process of the bag type dust collector, the filter bag is easy to collapse due to the negative pressure generated by the suction effect of the fan, so that a proper filter bag frame is required to be used for supporting and fixing, and meanwhile, the abrasion between the filter bag and the framework in ash removal is avoided. In addition, most of fixing and supporting components in the existing frame manufacturing technology are welding parts, the welding process is easy to generate off-welding, false welding and missing welding, and the welding points are easy to generate weld scars, so that the contact surface of the frame and the filter bag is not smooth and smooth enough, the filter bag is worn, and the service life of the filter bag is influenced. For example, chinese patent application No. 201310098076.8, 2013, 6, 26 discloses a filter bag frame for a bag filter. Although the components of the filter bag frame can be connected without welding, the service life of the filter bag is prolonged, the filter bag frame is only suitable for a straight cylindrical conventional dust collection cloth bag, the effective filtering area is small, the filtering wind speed is high, and the energy consumption is high. The pleated filter bag increases the surface area of the cloth bag body through the pleat mode so as to increase the filtering area, and the filtering wind speed of dust-containing air flow after passing through the pleated filter bag can be obviously reduced; thereby overcoming this drawback.
With the continuous strictness of environmental protection emission standards, bag dust removal should improve the cloth bag besides optimizing the design of the bag dust collector body in order to meet the increasing capacity requirement and the ultra-low emission requirement proposed by the nation. The cost of reforming the main structure of the bag type dust collector is great, and many industrial enterprises do not reserve space, so that the volume of the dust collector is increased unprecedentedly, and the filtering area cannot be increased in terms of increasing the number of cloth bags, so that the filtering area can be increased only by reforming the cloth bag structure, and the pressure drop and the dust emission concentration of the dust collector are reduced. The research shows that the longer the filter bag is, the smaller the peak pressure of the wall surface of the bottom of the filter bag is, which is unfavorable for ash removal, so the designed filter bag and the frame thereof cannot be overlong. Most of the existing pleated filter bag frames in the market cannot be adjusted in terms of the filtering area once the structural size is determined, so that the improvement of the filter bag frame structure to better adapt to the increasing requirements of the filtering areas of different pleated filter bags is a technical problem to be solved by those skilled in the art.
For example: chinese patent application No. 201710031158.9, patent application publication No. 2017, no. 3 and No. 22, discloses a pleated filter cartridge dust collector, a filter cartridge frame thereof and a use method of the frame, and belongs to the technical field of industrial dust collection. Although the design of the pleated filter cylinder frame can pointedly solve the problem that the filter material of the filter cylinder of the conventional pleated filter cylinder deduster is easy to deform, the filtering effect is effectively improved, and the ash removal difficulty is reduced. However, neither the pleat formation provided along the periphery of the lower end cap nor the annular pleat formation of the support ring are adjustable for the pleat parameters, meaning that the frame is only suitable for a certain number of pleats or pleat depth of the pleated filter insert.
Another example is: chinese patent application No. 201621061472.9, patent application document of publication No. 2017, 3 and 29, discloses a novel cloth bag cage. Although the bag cage can support the pleated filter bag, the abrasion possibility of the filter bag is reduced to the minimum, and the service life of the filter bag can be effectively prolonged. However, in the design of the bag cage, a series of bending and flanging are required to be carried out in order to prevent the bottom end of the longitudinal wire from scratching the cloth bag, so that the manufacturing process is more and the cost is high. Moreover, the bag cage is only suitable for filter bags of a certain specification, and a new bag cage can be replaced by sleeving a pleated cloth bag of another specification.
Another example is: a pleated cloth bag skeleton disclosed in Chinese patent application No. 201721229104.5, 2018, 4 and 17, which belongs to the technical field of filtering equipment. The pleated cloth bag skeleton can improve the filtering area of the filtering bag, but all the radial stay bars, the supporting inner rings, the arc stay bars, the supporting longitudinal stays and the auxiliary longitudinal stays are fixed by welding technology, the pleated parameters and the length of the skeleton can not be adjusted, and the pleated cloth bag skeleton is only suitable for the pleated filtering bag with one specification determined under a certain filtering area.
