Description

Bag type dust collector dust removal filter bag with sealed bag bottom buckled

Technical Field

The invention relates to a dust removal filter bag with a novel bag bottom structure, and belongs to the field of environment-friendly dust removal.

Background

Bag dust removal is an older dust removal technology. It has been used abroad as early as the 80 th century, and has been in the history of over two hundred years. In the middle of the eighties of the last century, under the influence of a series of environmental events in developed countries, China pays attention to the environmental protection career of the country, and the bag type dust removal industry is in the initial initiative of China. With the continuous progress of the technology, the efficiency of bag type dust removal is gradually improved, the bag type dust removal device can adapt to most dust removal working conditions, the air volume processing is large, the pressure of equipment is small, and the bag type dust removal device becomes the most widely applied dust removal technology in the dust removal industry. Currently, in the pollution control in the industrial industry, bag-type dust removal becomes a mode of upgrading and preferentially selecting ultralow emission, the bag-type dust removal accounts for 90% in the building material industry, the bag-type dust removal accounts for more than 80% in the steel industry, the bag-type dust removal is completely used in garbage incineration, nearly 50% in the coal-fired power plant industry and the like, and the bag-type dust removal plays a very important role in fighting against defending and attacking the hard in the atmosphere in the blue sky.

In bag-type dust removal, dust is mainly filtered through a dust filter bag to achieve the purpose of dust removal, so that the dust filter bag is a core component of a bag-type dust collector, and the dust removal efficiency of the bag-type dust collector is determined by the dust filtering performance of the dust filter bag. At present, most filter materials for manufacturing the dust removal filter bag have excellent dust filtering performance, but the dust filtering performance of the dust removal filter bag is far lower than that of the filter materials. This is because the filter material is made into a dust filter bag, and the filter material needs to be sewn. When the dust removing filter bag is manufactured, needle holes are left due to sewing of needle threads, and gaps are formed at the overlapped and sewn positions of the two pieces of cloth. The needle hole and the gap can be used as main dust exhaust channels, and have serious influence on the dust filtering performance of the dust removal filter bag.

At present, when the bag bottom of the dust-removing filter bag is manufactured in the industry, a cylindrical bag body filter material and another blind plate type bag bottom filter material are sewn into a whole by using threads to form the bag bottom of the dust-removing filter bag. The bag bottom manufacturing process has the following defects:

firstly, sewing must form needle holes, and the needle holes formed by sewing and positioned at the bottom of the dust removal filter bag are large and are extremely large in number. Practice has shown that these pinholes are the main dust exhaust channel, reducing the filtering performance of the filter bag. In order to solve the problem of the generated pinholes, some workers in the industry increase the working procedures and adopt a pinhole gluing technology. But the glue layer is easy to fall off, and the gluing process also increases the cost, so that the problem of dust exhaust channel formed by the pinhole at the bottom of the bag cannot be fundamentally solved.

And secondly, sewing is performed to connect the two filter materials, so cloth seam gaps can be left between the two overlapped and sewn filter materials, and the gaps are also dust exhaust channels. The personnel in the industry usually adopt the rubber coating mode to block, but the operation is difficult to the glue film easily drops, and the cost is higher, can't solve the dust exhaust passageway problem of cloth seam gap fundamentally.

Thirdly, the existing technology for manufacturing the bag bottom of the dust-removing filter bag is difficult to realize the operation of a mechanical production line. Up to now, the sewing of the bag bottom is all a manual single-process operation. Therefore, the production efficiency is low, the cost is high, and the needle hole dust exhaust passage still exists.

CN102284215A discloses a preparation method of a dust-removing filter bag, which comprises bag body preparation, bag opening preparation and bag bottom preparation. The bag bottom is prepared by turning the bag body and sewing the edge of the bag bottom in an embedded mode. The method only reduces the dust discharge of the cloth seam to a certain extent, but can not fundamentally solve the dust discharge problem of the seam and the needle eye because the sewing process is still adopted. CN104436866B discloses a manufacturing method of a non-pinhole dust removal filter bag, which is characterized in that a composite single-sided sintered and shaped micropore belt is hot-pressed on a sewing needle thread of the filter bag. Because the structure of the bag bottom of the dust removal filter bag is complex, the method can not be applied to the bag bottom, so that the microporous belt only covers the needle seams of the bag body and the bag opening, and the dust removal problem of the needle holes and cloth seam seams at the bag bottom can not be solved.

The invention provides a solution for solving the problems of the prior dust-removing filter bag bottom.
