Description
Technical Field
The utility model relates to a combined type dust remover field, specifically speaking relates to a novel combined type dust remover of adaptable different work condition.
Background
The pollution of industrial waste gas to the atmosphere cannot be ignored. Fine particles contained in industrial exhaust gas are one of the important sources of air pollution problems such as haze and the like. Therefore, the research and improvement of the industrial dust removal technology are very important for treating the atmospheric pollution.
The most common equipment for industrial dust removal at present is a bag-type dust remover, a filter cartridge dust remover, a cyclone separator and the like. The bag-type dust collector is most widely used, has high dust collection efficiency which can reach more than 99 percent and can filter micro particles below 5 microns. However, in order to improve the dust collection efficiency and the service life of the filter bag and reduce the energy consumption, the air flow speed and the particle size of the particles entering the bag-type dust collector are generally not too large, for example, the filtering air speed of the glass fiber bag-type dust collector with relatively high strength is about 0.5-0.8 m/s, and the particle size of the particles to be treated is usually below 5 microns. And the high temperature and high humidity environment has great adverse effect on the filtering efficiency and the service life of the filter bag. The cartridge dust collector features are similar to a bag-type dust collector. The cyclone separator has a slightly lower filtering efficiency than a bag-type dust collector or a filter cartridge dust collector, and generally treats particles with the particle size of more than 15 microns, and the efficiency is about 80-85%. However, the requirement on the air flow condition is not high, and the special air flow such as high temperature, high humidity and the like can be treated.
Currently, some industrial dust removal systems employ multi-stage filtration in order to compensate for the short plates of various types of dust removal devices. Take cyclone separators and bag house collectors as examples: the dusty airflow enters the cyclone separator after being captured by the exhaust hood, and most of particulate matters, especially particles with larger particle sizes, can be settled under the action of gravity and the like; then the smaller particles enter the bag type dust collector along with the air flow and are filtered by the cloth bag, and finally the clean air flow is discharged through the exhaust pipeline.
However, the multistage filtration generally occupies a large area, the pipeline is complex, the capability of adapting to the working environment is poor, the energy consumption is high, and the design and maintenance cost is high.

In the cyclone separator 1, dust with larger particles in the dust-containing gas is discharged from a lower outlet of the cyclone separator 1, and gas with smaller particles in the dust is discharged from an upper gas outlet and enters the high-efficiency dust removal chamber 2. The partition 3 divides the high-efficiency dust removal chamber 2 into an upper clean gas sub-chamber 4 and a lower dust removal sub-chamber. The gas exiting the cyclone 1 enters the lower dust extraction sub-chamber of the high efficiency dust extraction chamber 2. In the lower dust removal subchamber, the gas containing smaller dust particles is filtered by the filter element 5 to become clean air, and the clean air passes through the filter element 5 and enters the upper clean gas subchamber 4.
The combined type dust remover of this embodiment, through 1 first grade filtration of cyclone, through 5 second grade filtrations of filter core, realized gaseous purification again. Through setting up two-stage filtration for gas purification is more thorough. The combined type dust remover of the embodiment has a compact structure, and can be arranged in a workshop to realize air purification.

And the gas inlet of the cyclone separator 1 is a dust-containing gas inlet. In this embodiment, the number of the filter elements 5, the number of the cyclone separators 1, and the arrangement mode are determined by specific working conditions and device environmental conditions. The preferred embodiment exemplifies two cyclone separator 1 arrangements: as shown in fig. 2, the cyclone separators 1 are arranged at two opposite sides of the high-efficiency dust removal chamber 2; as shown in fig. 3, the cyclone separator 1 is arranged at the peripheral side of the high-efficiency dust removing chamber 2. Through reasonable arrangement of the cyclone separator 1, the purification of air in a plant can be realized. If a production line is started up on one side of the plant, the cyclone 1 corresponding to that side can be started up. If all lines of the plant are started up, all cyclones 1 can be started up.
By adopting the structure, the two-stage filtering device is integrated into one device, and the space volume of the device is greatly reduced by arranging the shared ash bucket.
As a preferable example, the composite dust remover also comprises an ash hopper 6. The ash bucket 6 is positioned at the lower part of the high-efficiency dust removal chamber 2. The ash hopper 6 is connected with a dust outlet at the bottom of the cyclone separator 1. The ash bucket 6 is shared by the cyclone separator 1 and the high-efficiency dust removal chamber 2. The dust collecting device can conveniently collect dust, is convenient for daily management and maintenance, and reduces the occupied space of the device.
In the preferred embodiment, the dust-containing gas enters the cyclone separator 1 from the dust-containing gas inlet, firstly, in the dust removing process of the cyclone separator 1, the particulate matters larger than 15 micrometers are separated and enter the dust hopper 6, then the airflow with most of dust removed enters the high-efficiency dust removing chamber 2, after the dust removing effect of the filter element 5, the particulate matters smaller than 15 micrometers are captured, and the clean airflow enters the upper clean gas sub-chamber 4 and then is discharged from the clean gas outlet 7.

When the ash removal treatment of the filter element 5 is needed, the electromagnetic pulse valve 9 is started, and the gas in the gas bag 8 is ejected out of the injection pipe 10 in a pulse mode. Because the air outlet of the blowing pipe 10 is opposite to the bag opening of the filter element 5, the sprayed air forms pulse to the bag body of the filter element 5 and flows from the inner side of the filter element 5 to the outer side of the filter element 5. This achieves the ash removal treatment of the filter element 5. The dust detached from the filter element 5 falls into the dust hopper below.

And the hole air passage is provided with a lift valve which can control the communication or cut-off state of the high-efficiency dust removal chamber and the air purification chamber.
The types of fumes produced are different due to the industrial industry. However, the filter element 5 has high requirements on flue gas, such as not too high temperature and humidity, not too large air volume and the like. However, the cyclone separator 1 has the characteristics of high temperature resistance and wear resistance. Therefore, the dusty gas firstly enters the cyclone separator 1, so that the requirements of different working conditions can be better met, the flow speed and the temperature of the dusty gas flow can be reduced, larger-particle-size particles can be separated, the workload of the filter element 5 is reduced, and the working requirements of the filter element 5 are met. Meanwhile, the cyclone separator can only remove large particles larger than 15 micrometers, the efficiency is low, but the filter element can remove fine particles smaller than 15 micrometers, and the dust removal efficiency is high, so that the filter elements 5 are sequentially arranged behind the cyclone separator 1, and the advantages can be complemented.
In the dust remover of the embodiment, the filter element 5 in the high-efficiency dust removing chamber 2 can be replaced, so that different dust removing requirements can be met; the position of the cyclone separator 1 is variable, so that different working environments and working condition requirements can be met; the ash bucket is shared, so that the space can be saved and the cleaning is convenient.
