Description

A prevent inhaling flat section of thick bamboo of straining for sound wave deashing

Technical Field

The utility model belongs to the technical field of the environmental protection dust removal and specifically relates to a prevent inhaling flat section of thick bamboo of straining for sound wave deashing.

Background

With the higher and higher national requirements on environmental protection, the ultra-low emission of dust is a great trend. In the dust removal of the metallurgical industry, ultralow emission is realized, the conventional scheme is to increase the filtering area of the dust remover, and the measures for increasing the filtering area of the dust remover comprise two measures: (1) the newly-built project increases the filtering area by enlarging the occupied area of the dust remover, and has the defects of large occupied area and increased primary investment cost; (2) the project of transformation is divided into two cases: the land of a factory area is abundant, and the old dust remover is directly expanded, so that the defects of large occupied area and increased one-time investment cost are overcome; secondly, transforming the old dust remover when the land in the factory is short, wherein the traditional scheme is to lengthen a filter bag or adopt a filter cylinder; the lengthened filter bag relates to factors such as heightening of a dust remover body and the like, and has the defects of long construction period, long shutdown time of a system and influence on production; the filter cartridge is adopted, in order to increase the filtering area, the filter screen layer is usually folded into a zigzag shape, and the filter cartridge has the defects that the filter cloth of the existing filter cartridge on the market is spun-bonded non-woven fabric or melt-blown non-woven fabric, the strength is low, adjacent folds can be shriveled in the using process, as shown in figure 5, the filtering area is easy to lose efficacy, the air permeability is poor, the resistance of a dust remover is high, pulse blowing is adopted for ash removal, the surface coating of the filter cloth can be damaged by frequent blowing, and the service life of the filter cartridge is.

Patent CN209809739U mentions a filter cartridge for preventing from being shriveled, wherein an air-permeable support member is arranged in the inner saw tooth grooves of the filter screen layer, the air-permeable support member is filled in the inner saw tooth grooves, the shape of the air-permeable support member is matched with that of the inner saw tooth grooves, and the air-permeable support member is an air-permeable foaming agent. The foaming agent of the air-permeable supporting piece matched with the shape of the inner saw tooth groove is utilized to realize absolute opening of the filter screen layer, the absolute opening inevitably requires more contact area between the air-permeable supporting piece and the filter screen layer, and the filter screen layer can be covered, so that the filter area is reduced, the filter effect is influenced, and the absolute opening is unnecessary; the air-permeable supporting member adopted by the filter material can affect the smoothness of air flow and the filtering effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a prevent inhaling flat section of thick bamboo of straining for sound wave deashing solves that the above-mentioned dust remover area that arouses for realizing ultralow emission is big, the investment cost is high and strain a gas permeability poor, easily inhale flat, resistance high, the tectorial membrane is damaged, the construction cycle is long by the jetting easily problem.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a prevent inhaling flat section of thick bamboo that strains for sound wave deashing, a prevent inhaling flat section of thick bamboo that is used for sound wave deashing, includes upper end cover, lower extreme cover, locates the round filter cloth layer that organ fold form was arranged between upper end cover and the lower extreme cover and is used for supporting the cage bone on filter cloth layer, the filter cloth layer is equipped with fixing strap outward, the cage bone sets up in main cage bone outlying keel a plurality of including main cage bone and dispersing, main cage bone is connected with upper end cover, lower extreme cover, each keel is filled in the interior fold on organ fold form filter cloth layer.

The sub keel is of a spiral blade structure.

The filter cloth layer is a needle-punched non-woven fabric of a coated film subjected to gum dipping and hardening treatment.

The utility model discloses it has helical blade structure form keel to fill in the interior pleat of organ pleated filter cloth layer for under the condition that inside convulsions produced suction, strut filter cloth layer folded sheet, prevent that these two filter cloth folded sheets from being sucked, though do not realize absolute strut, nevertheless really as long as realize that filter cloth layer folded sheet does not laminate together, can reach abundant also the biggest filter effect, guarantee its filtration area and filter effect; the utility model discloses helical blade structure form fossil fragments are the point contact with organ fold form filter cloth layer under not receiving the suction effect, and general point contact all causes pressure or damage to the filter cloth layer easily, and the face contact probably covers filter area again, and the firm surface of being simultaneously of the sub-fossil fragments has both been guaranteed in helical blade structure form fossil fragments's design is the arc design, receiving under the suction effect, the point contact becomes soft line contact, reduces the sub-fossil fragments and causes pressure or damage to the filter cloth layer.

After the filter cloth layer of the utility model is treated by gum dipping and hardening, the strength is improved, thereby improving the pressure resistance of the filter cylinder, and the folds are not easy to be shriveled; meanwhile, the inherent frequency of the filter cylinder is reduced by the hardening treatment, the filter cylinder is suitable for sound wave ash removal, and the sound wave ash removal replaces the conventional pulse ash removal, so that the service life of the filter cylinder can be prolonged, a plurality of complicated gas path elements for pulse ash removal are saved, and the maintenance of a later-stage dust remover is greatly facilitated; the laminated needled felt is adopted, so that ultralow emission is ensured, the air permeability (proved by experimental data) is increased by 2 times compared with that of a conventional filter cylinder, and the resistance of a dust remover is reduced, so that the operation energy consumption of the whole system is reduced; the dust remover adopts the filter cylinder, the same filtering area occupies less area, and thus, the one-time investment is reduced; if the method is applied to the transformation of the existing dust remover, the construction period is short, and the system downtime is reduced.

The utility model discloses simple structure, the cost is not high, long service life, and the application is respond well.
