Description

A new type of compound dust collector that can adapt to different working conditions

technical field

The utility model relates to the field of compound dust collectors, in particular to a novel compound type dust collector which can adapt to different working conditions.

Background technique

The air pollution caused by industrial waste gas cannot be ignored. The fine particulate matter contained in industrial waste gas is one of the important sources of air pollution problems such as smog. Therefore, the research and improvement of industrial dust removal technology is very important to control air pollution.

At present, the most commonly used equipment for industrial dust removal are bag filter, filter cartridge filter, cyclone and so on. Among them, the bag filter is the most widely used, and its dust removal efficiency is high, which can reach more than 99%, and can filter tiny particles below 5 microns. However, in order to improve the dust removal efficiency and service life of the filter bag and reduce energy consumption, generally speaking, the air velocity and particle size entering the bag filter should not be too large. It is about 0.5-0.8m/s, and the particle size of the treated particles is usually below 5 microns. And the high temperature and high humidity environment have great adverse effects on the filtration efficiency and service life of the filter bag. Cartridge filter features are similar to bag filter. Compared with bag filter or cartridge filter, the filtration efficiency of cyclone separator is slightly lower, and it usually deals with particles above 15 microns, and the efficiency is about 80% to 85%. However, it does not require high airflow conditions, and can handle special airflows such as high temperature and high humidity.

At present, in order to make up for the shortcomings of various dust removal devices, some industrial dust removal systems use multi-stage filtration. Take the cyclone separator and bag filter as examples: the dust-laden airflow will enter the cyclone separator after being captured by the exhaust hood, and most of the particles, especially those with larger particle size, will settle down due to gravity and other effects; The particles enter the bag filter with the airflow and are filtered by the bag filter, and finally the clean airflow is discharged through the exhaust pipe.

However, multi-stage filtration generally occupies a large area, the pipeline is more complicated, the ability to adapt to the working environment is poor, the energy consumption is high, and the design and maintenance costs are high.

In order to further understand the technical solution of the present utility model, the present utility model is described in detail below with reference to the accompanying drawings and embodiments.

As shown in FIG. 1 , the embodiment of the present utility model provides a new type of composite dust collector, which includes a cyclone separator 1, a high-efficiency dust removal chamber 2 and a partition 3. The cyclone separator 1 is arranged around the outer wall of the high-efficiency dust removal chamber 2. The plate 3 is located at the upper part of the high-efficiency dust removal chamber 2, and the partition plate 3 is provided with holes. The partition plate 3 divides the high-efficiency dust removal chamber 2 into an upper clean air sub-chamber 4 and a lower dust removal sub-chamber; the filter element 5 of the high-efficiency dust removal chamber 2 is connected to On the holes of the partition plate 3, the filter element 5 is located in the lower dust removal chamber, the cyclone separator 1 is slidingly connected with the wall surface of the lower dust removal chamber of the high-efficiency dust removal chamber 2, and the airflow outlet of the cyclone separator 1 is connected to the high-efficiency dust removal chamber. 2 for the flue gas inlet connection. Figure 1 only lists the main components, and the connecting components, valves, etc. are not shown in the figure. Preferably, the filter element 5 is a bag filter or a filter cartridge filter. Of course, the filter element 5 can also be in other structural forms. The upper clean air sub-chamber 4 is provided with a clean air outlet 7 . The clean air outlet 7 supplies clean air to flow out from the high-efficiency dust chamber 2 .

In the composite dust collector of the above embodiment, the external dust-containing gas enters the high-efficiency dust removal chamber 2 through the cyclone separator 1 . In the cyclone separator 1, the dust with larger particles in the dust-containing gas is discharged from the lower outlet of the cyclone separator 1, and the gas containing smaller dust particles is discharged from the upper gas outlet and enters the high-efficiency dust removal chamber 2. The partition 3 divides the high-efficiency dust chamber 2 into an upper clean gas sub-chamber 4 and a lower dust-removal sub-chamber. The gas discharged from the cyclone separator 1 enters the lower dust collector chamber of the high-efficiency dust chamber 2 . In the lower dust sub-chamber, the gas containing smaller dust particles is filtered by the filter element 5 and becomes clean air, which passes through the filter element 5 and enters the upper clean air sub-chamber 4 .

The composite dust collector of this embodiment is filtered through the first stage of the cyclone separator 1, and then filtered through the second stage of the filter element 5, so as to realize the purification of the gas. By setting up two-stage filtration, the gas purification is more thorough. The composite dust collector of this embodiment has a compact structure and can be placed inside the workshop to realize air purification.

In addition, in this embodiment, the number of bag filter (or filter cartridge filter), the number and arrangement of cyclone separators are not limited to those listed in this embodiment. The air inlets of the cyclone separator 1 are all dust-laden gas inlets. In this embodiment, the number of the filter elements 5, the number and arrangement of the cyclone separators 1 are determined by the specific working conditions and the environmental conditions of the device. This preferred example exemplifies two arrangements of the cyclones 1: as shown in Figure 2, the cyclone 1 is arranged on two opposite sides of the high-efficiency dust chamber 2; as shown in Figure 3, the cyclone 1 is arranged in the high-efficiency dust chamber 2 around the sides. By reasonably setting the cyclone separator 1, the air purification in the workshop can be realized. If the production line is started on one side of the plant, the cyclone 1 corresponding to that side can be started. If all production lines in the plant are activated, then all cyclones 1 can be activated.

By adopting the above structure, the two-stage filtering device is integrated into one device, and the space volume of the device is greatly reduced by arranging a common ash hopper.

As a preferred example, the compound dust collector also includes an ash hopper 6 . The ash hopper 6 is located at the lower part of the high-efficiency dust chamber 2 . The ash hopper 6 is connected with the dust outlet at the bottom of the cyclone separator 1 . The ash hopper 6 is shared by the cyclone separator 1 and the high-efficiency dust removal chamber 2 . Such an arrangement can facilitate dust collection, facilitate daily management and maintenance, and reduce the space occupied by the device.

In the above preferred example, the dust-laden gas enters the cyclone separator 1 from the dust-laden gas inlet, and first passes through the dust removal process of the cyclone separator 1, and the particles larger than 15 microns are separated into the ash hopper 6, and then the airflow that removes most of the dust enters. In the high-efficiency dust removal chamber 2, after the dust removal of the filter element 5, the particles smaller than 15 microns are captured, and the clean airflow enters the upper clean air sub-chamber 4, and then is discharged from the clean air outlet 7.

Preferably, the composite dust collector further includes a pulse jet cleaning device, the pulse jet cleaning device is located in the upper clean air sub-chamber 4 , and the pulse jet dust cleaning device is located above the partition plate 3 . Preferably, the pulse jet cleaning device includes an air bag 8 , an electromagnetic pulse valve 9 and a blow pipe 10 , the air outlet of the blow pipe 10 is opposite to the bag opening of the filter element 5 , and the electromagnetic pulse valve 9 is located in the blow pipe 10 .

In the high-efficiency dust removal chamber 2, the filter bag (or filter cartridge) in the filter element 5 uses compressed air for pulse jet cleaning. When the filter element 5 needs to be cleaned, the electromagnetic pulse valve 9 is activated, and the gas in the air bag 8 is sprayed out of the blowing pipe 10 in the form of pulses. Since the air outlet of the blowing pipe 10 is opposite to the bag opening of the filter element 5 , the ejected gas forms a pulse on the bag body of the filter element 5 , and the direction flows from the inside of the filter element 5 to the outside of the filter element 5 . This realizes the cleaning process of the filter element 5 . The dust detached from the filter element 5 falls into the ash hopper below.

Preferably, the filter element 5 of the high-efficiency dust removal chamber 2 is connected with the holes of the partition plate 3 by screw threads. Threaded connection is a detachable fixed connection, which has the advantages of simple structure, reliable connection, and convenient assembly and disassembly. Therefore, the bag filter or the filter cartridge filter can be quickly exchanged by itself or with each other.

Preferably, the compound dust collector further includes an automatic adjustment valve, and the automatic adjustment valve is arranged at the flue gas inlet of the cyclone separator 1 . Adjust the opening of the automatic regulating valve according to the requirements of the working conditions, and change the inlet component and wind speed. Of course, the number of cyclones to be used or closed can also be determined depending on the air volume requirements.

As a preferred example, the compound dust collector further includes a lift valve, and the lift valve is arranged above the air passage of the 3 holes in the partition plate. The hole air passage is provided with a poppet valve that can control the communication or cut-off state between the high-efficiency dust chamber and the clean air chamber.

Due to different industrial industries, the types of flue gas produced are also different. However, the filter element 5 has higher requirements on the flue gas, such as the temperature and humidity should not be too high, and the air volume should not be too large. However, the cyclone separator 1 has the characteristics of high temperature resistance and wear resistance. Therefore, the dust-laden gas first enters the cyclone separator 1, which can not only better meet the requirements of different working conditions, but also reduce the dust-laden airflow velocity and airflow temperature, separate larger-sized particles, reduce the workload of the filter element 5, and meet the The working requirements of filter element 5. At the same time, the cyclone separator can only remove large particles larger than 15 microns, and the efficiency is low, but the filter element can remove fine particles smaller than 15 microns, and the dust removal efficiency is very high, so the filter element 5 is arranged in sequence behind the cyclone separator 1. , can complement each other's advantages.

In the dust collector of the above embodiment, the filter element 5 in the high-efficiency dust removal chamber 2 can be replaced, which can meet different dust removal requirements; the position of the cyclone separator 1 can be changed to meet the requirements of different working environments and working conditions; the shared ash hopper can be used. Space saving and easy cleaning.
