Description

Ceramic fiber folding filter element

Technical Field

The utility model relates to a high temperature gas cleaning technical field especially relates to a folding filter core of ceramic fibre.

Background

At present, filter bags are mostly adopted to carry out high-temperature flue gas purification treatment in various production fields of chemical industry and oil products. Because the materials of the filter bag are mainly polyester, glass fiber and the like, the filter bag is only used at the temperature of 200 ℃, and the high-temperature flue gas needs to be sprayed and cooled during working under the high-temperature condition, so that the equipment is increased, the process is complex and the cost is increased.

The ceramic filter is an ideal choice, can be directly used at high temperature, avoids cooling treatment and has relatively low cost. The Chinese utility model patent "a novel high temperature resistant ceramic fiber filter tube" (CN208642106U) discloses a high temperature resistant ceramic fiber filter tube, and this high temperature resistant ceramic fiber filter tube inner wall pipe is enclosed by three lengthwise piece end to end and closes and forms, and the transversal crescent of personally submitting of lengthwise piece. However, the longitudinal pieces are integrally made by bonding, the filtering area is limited, a plurality of ceramic fiber filtering pipes are needed to be used simultaneously when high-temperature flue gas with large treatment capacity is treated, the cost is high, and the whole occupied area of the filter is large.

In view of the above, there is a need for an improved ceramic fiber filter tube in the prior art to solve the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to disclose a ceramic fiber folding filter core, improve the filter area of high temperature flue gas treatment with the filter core, reduce use cost, the spacing recess of simultaneous design can realize quick installation.

In order to realize the above object, the utility model provides a folding filter core of ceramic fibre, folding filter core of ceramic fibre includes the sub-folding filter plate of a plurality of, sub-folding filter plate is the wave type folding, is connected with the vertical strengthening rib of arranging of a plurality of between the folding filter plate of adjacent sub-, the strengthening rib that is located the folding filter core both sides of ceramic fibre is equipped with spacing recess, spacing recess extends along strengthening rib lengthwise extending direction in step, sub-folding filter plate and strengthening rib formula structure as an organic whole.

In some embodiments, the number of ribs is four.

In some embodiments, the sub-folded filter plate has a double-layer structure, the pore diameter of the outer layer of the sub-folded filter plate is 1-10 μm, and the pore diameter of the inner layer of the sub-folded filter plate is 0.1-1 μm.

Compared with the prior art, the beneficial effects of the utility model are that: (1) the sub-folding filter plate structure effectively increases the filtering area, improves the filtering efficiency, and improves the dirt holding capacity of the ceramic fiber folding filter element; (2) the ceramic fiber folding filter element is integrally formed, so that the mechanical property is more excellent, and the shock strength is good; (3) the sub-folding filter plate has a double-layer structure, the sizes of micropores are distributed in a gradient manner, and the filtering efficiency is better; (4) the design of limiting grooves can realize quick disassembly and assembly.
