Description

Technical Field

[0001] The utility model relates to a dust-containing waste gas treatment device, in particular to a bag filter with a combined installation interface. Background Technique

[0002] The bag filter is a dry dust filtering device, which is suitable for collecting fine, dry and non-fibrous dust. Due to the advantages of low cost, high dust removal efficiency and convenient maintenance of the bag filter, it is widely used. In industries such as heating, thermal power, metal smelting, and non-metallic mineral product processing, the bag filter is basically used for the purification treatment of waste gases such as boiler flue gas and production tail gas generated during the production operation of enterprises. However, with the gradual improvement of national environmental protection laws and regulations, the environmental protection discharge standards have become gradually strict in recent years. Enterprises have only two options to meet the "ultra-low emission" requirements: optimizing environmental protection treatment technologies or replacing environmental protection equipment. For the replacement of dust collectors or the selection of new treatment technologies, there is an obvious drawback, that is, enterprises have to bear high transformation costs. The bag filter with a combined installation interface of the utility model can, while keeping the original system equipment in normal use, increase the filtration area, meet the discharge standards, and reduce the enterprise cost by simply and quickly installing the dust collector. Content of the Utility Model

[0003] The purpose of the utility model is to provide a bag filter with a combined installation interface, which has the advantages of on-site modularization, simple and quick assembly of the dust collector, solves the problem that when the existing dust collector needs to increase the dust removal area, it is necessary to dismantle the dust collector and then replace it with a new one, and the need to replace its supporting electrical equipment, reduces the cost for enterprises to improve environmental protection standards, and at the same time opens up a new modular assembly mode for dust collectors, increasing the core competitiveness of dust collector products.

[0004] To achieve the above object, the present utility model provides the following technical solutions: A bag filter with a combined installation interface, comprising a steel support, a middle box body fixedly connected to the top of the steel support, the middle box body being a square columnar structure, a dust hopper assembly fixedly connected to the bottom, the dust hopper assembly being an inverted pyramid structure, an insertion plate valve fixedly connected to the lower end, a discharger fixedly connected to the lower end of the insertion plate valve, an upper box body fixedly connected to the upper part of the middle box body, a blowing system assembly installed inside the upper box body, the blowing system being connected to a pulse valve, a bag cage installed inside the middle box body, a filter bag sleeved on the bag cage, an air chamber being simultaneously arranged inside the middle box body, the air chamber being divided into an upper air chamber and a lower air chamber by an air chamber partition, the upper air chamber being communicated with the upper box body and being communicated with an upper air chamber connection port arranged on both sides of the middle box body, the lower air chamber being communicated with the dust hopper and being communicated with a lower air chamber connection port arranged on both sides of the middle box body. The lower air chamber is an intake channel for dusty exhaust gas. The exhaust gas enters the dust hopper through the lower air chamber, then enters the middle box body, and after being filtered by the cloth bag, the clean gas enters the upper box body, enters the upper air chamber through the space of the upper box body, and then is discharged.

[0005] Preferably, the air chamber is designed in an "H" shape.

[0006] Preferably, when the upper air chamber connection port and the lower air chamber connection port are not connected, they are sealed with blind plates, and when connected, one end is kept sealed and the other end is the intake and exhaust port.

[0007] Compared with the prior art and equipment, the beneficial effects of the present utility model are as follows:

[0008] The bag filter with a combined installation interface of the present utility model can achieve multiple combined installations under the condition of matching the fan parameters to increase the filtration area, and further meet the more environmentally friendly emission requirements. At the same time, when the equipment needs to be repaired or replaced, it can be repaired or replaced modularly, which is beneficial to the cost control of the enterprise and reduces the production cost of the enterprise. At the same time, due to the ability to perform modular assembly simply and quickly on-site, the present utility model increases the product competitiveness of the dust collector product and is beneficial to the realization of the quality and production standardization of the environmental protection product.

Detailed implementation mode

[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0013] The steel support 1, discharge valve 2, flap valve 3, ash hopper 4, middle box body 6, upper box body 8, pulse valve 9, injection assembly 10, cage 12, and filter bag 15 components of the present utility model are all common standard parts or parts known to those skilled in the art. Moreover, the standard parts used in this application document can be purchased from the market, and can be customized according to the description in the specification and the drawings. Their structures and principles can all be known by those skilled in the art through technical manuals or through conventional experimental methods. The structure composed of the H-type air chamber cabin and the connected air chamber wall 13, air chamber partition 14, upper air chamber connection port 5, and lower air chamber connection port 7 components of the present utility model is a unique component structure of the present utility model, not a common standard part or a part known to those skilled in the art.

[0014] Please refer to Figures 1 - 4 , a bag filter with a combined installation interface, the upper air chamber connection port 5 and the lower air chamber connection port 7 of which are the combined installation interfaces described in the present utility model, and the modular assembly and combined installation of the dust collector can be carried out on site. During combined installation, only the upper and lower air chamber connection ports of the two dust collectors need to be connected and fixed.

[0015] During use, there are 2 remaining upper air chamber connection ports and 2 remaining lower air chamber connection ports on the combined-installed dust collector. One air chamber connection port on the upper and lower air chambers is respectively closed with a blind plate, and the remaining 1 lower air chamber connection port is the inlet for dusty waste gas, and the remaining 1 upper air chamber connection port is the clean gas exhaust port. The dusty waste gas enters the ash hopper through the lower air chamber, and then the waste gas enters the middle box body. After being filtered by the cloth bag, the clean gas enters the upper box body, enters the upper air chamber through the space of the upper box body, and then is discharged from the clean gas exhaust port. After working for a certain period of time, more dust accumulates on the surface of the filter bag. At this time, by setting the pulse valve 9, the accumulated dust is blown off by the injection assembly 10, and the dust falls into the ash hopper 4 by gravity. The dust is discharged through the flap valve 3 and the discharger 2.

[0016] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
