Problems solved by technology

[0002] At present, the known bag filter must not be used in the state of wet condensation, which is recognized at home and abroad. The reason is that after the bag is wet, the collected dust will stick to the filter material and cannot be removed. , causing the filter material to be airtight, to the point that the filter fails and cannot be used

Embodiment approach 1

[0021] Specific embodiment of the present invention 1 referring to Fig. 1, Fig. 2, by main box body 10, flower board 20, lower end and flower board fix four rows of cloth bags 8, lower box body 4, air inlet pipe whose upper end is suspended on the top plate by springs 17. The air outlet pipe 16 and the anti-blow pipe 11 constitute the main body of the dust collector. The cloth bag 8 with a design diameter of 15cm and a length of 2m is equipped with 4 bags with an outer diameter of 14.6cm at an even interval of 50cm that can move up and down. The ash scraping ring 9 is made of a steel wire with a diameter of 0.4cm, and each ash scraping ring is fixedly connected to the ash scraping rod 5 at the center of the ash scraping ring 9 with 4 connecting bars 19, and each ash scraping rod The lower end of 5 extends into the lower box body 4, and is fixed on the support 3 that does not prevent the dust from falling with bolts. The support 3 is connected to the telescopic rod equipped with...

Embodiment approach 2

[0033] According to the filtering method, the bag filter is divided into two types: inner filter and outer filter. The structure of the outer filter dust collector has an additional upper box, and a skeleton is added inside the cloth bag. Scheme 1 is the inner filter type, and scheme 2 is the outer filter type. In this way, the dust is collected on the outer surface of the bag. The specific structure of this scheme 2 is shown in Fig. 6 and Fig. 7, and the difference with scheme 1 is: dust-scraping ring 9 is enclosed within the outside of cloth bag 8.

[0034] The outer diameter of the frame is designed to be 14cm (due to the contraction of the bag during dust removal in the external filter type, there must be a frame to support the bag), the diameter of the bag when it is bulging is 15cm, and the outer cover of the bag 8 with a length of 2m is evenly spaced. The internal diameter of 50cm is 14.6cm (skeleton outer diameter at this moment will be less than about 0.6cm of ash scr...

Abstract

The present invention discloses a kind of bag-type dew-condensing dust-removing device specially-used for dew-condensing dampness. It is characterized by that it at least alternatively uses two dust-removing device, in which one is off-line for drying and cleaning dust, and another is used for normally removing dust. Said invention also equipped with a dry air-intake tube and a dry air door. After the dust is removed for a certain period of time, one dust-removing device is off-line, dried hot air is introduced so as to make cloth bag and dust be completely dried, then when it is used for making internal filtration the dust-scraping ring set in the cloth bag or it is used for making external filtration the dust-scraping ring set on the exterior of cloth bag can be controlled by cylinder and can be upwards and downwards moved, so that the dust can be completely removed.

Description

technical field [0001] The invention relates to a dust remover, in particular to a bag type dust remover which can be used for dew condensation. Background technique [0002] At present, the known bag filter must not be used in the state of wet condensation. This is recognized at home and abroad. The reason is that after the bag is wet, the collected dust will stick to the filter material and cannot be removed. , causing the filter material to be airtight, so that the filter becomes invalid and cannot be used. Contents of the invention [0003] In order to overcome the recognized technical problem of "the bag dust collector cannot be used for dew condensation", the present invention provides a bag type dust collector, which can solve the problem of bag paste and can be used in the dew condensation state. [0004] The technical solution adopted by the present invention to solve its technical problems is: the provided bag filter, which includes a main box, a lower box, an a...
