technical field

The utility model relates to the technical field of filter bag type dust removal, in particular to a filter bag type dust removal device.

Background technique

With the rapid development of my country's economy and the continuous improvement of people's living standards, the problem of domestic waste has become the most urgent environmental problem to be solved. Due to the many types of garbage, the difficulty of sorting, and the high cost of sorting, it is difficult to process garbage.

Currently, there are composting technology, landfill technology, incineration technology, and gasification technology for the harmless disposal of urban living garbage. Neither landfill nor compost can fully realize the harmlessness and reduction of waste disposal, and landfill still needs a large amount of land. Since incineration treatment can realize the purposes of thermal energy recovery, volume reduction, weight reduction, and high-temperature sterilization of urban waste, it has obvious advantages in environmental protection and resource utilization, so it has developed rapidly in my country in recent years. However, secondary pollution problems such as soot and heavy metals in the flue gas produced by waste incineration cannot be ignored, which restricts the large-scale application of waste incineration technology.

Therefore, in order to solve the above technical problems, it is necessary to provide a new type of dust removal equipment, which can cooperate with other flue gas treatment equipment to fundamentally solve the secondary pollution problems such as smoke dust and heavy metals.

In order to solve the above technical problems, the purpose of this utility model is to provide an efficient dust removal device, which has the characteristics of small footprint, safe operation and high processing efficiency.

The purpose of this utility model is achieved through the following technical solutions:

A bag dust removal device, comprising: an upper box (1), a solenoid valve (2), a lower box (3), an ash unloading valve (6), an air outlet (8) and an ash hopper (10);

The upper box (1) is arranged on the upper part of the dust removal device, and a guardrail (7) is arranged on the top of the upper box (1);

The electromagnetic valve (2) is arranged on the upper box (1), and cooperates with the bag to remove dust;

The lower part of the lower box (3) is provided with an air inlet (4);

The ash unloading valve (6) is arranged below the ash hopper (10), and fixed brackets (5) are provided on both sides of the ash unloading valve (6) and the ash hopper (10), for fixing the bag dust removal device.

Compared with the prior art, one or more embodiments of the present invention may have the following advantages:

The bag filter can make equipment maintenance and filter bag replacement safer and more convenient through the top ladder and guardrail, and at the same time reduce the occupied area to save costs;

The bag filter is equipped with a solenoid valve, which can improve the effect of dust removal and prolong the service life of the filter bag by controlling the pulse of the solenoid valve and blowing dust;

The bag filter adopts hydrophobic and oil-proof cloth bags to improve the adaptability to incineration flue gas and improve the dust removal efficiency;

The bag filter has no secondary pollution, the device does not produce polluted solids, has low noise, and does not emit toxic gases.

Description of drawings

Figure 1 is a schematic diagram of the overall structure of a bag filter.

Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the implementation of the utility model will be further described in detail below with reference to the examples and drawings.

As shown in Figure 1, it is the overall structure of the bag dust removal device, including the upper box 1, the solenoid valve 2, the lower box 3, the ash discharge valve 6, the air outlet 8 and the ash hopper 10;

The upper box is arranged on the top of the dust removal device, and a guardrail 7 is arranged on the top of the upper box; the solenoid valve is arranged on the upper box, and cooperates with bag cleaning; the lower part of the lower box is provided with The air inlet 4; the ash discharge valve is arranged under the ash hopper, and fixed brackets 5 are provided on both sides of the ash discharge valve and the ash hopper for fixing the bag dust removal device.

The above-mentioned electromagnetic valve includes a plurality of electromagnetic valves, and the plurality of electromagnetic valves are arranged horizontally on the upper part of the upper box.

The above-mentioned air outlet is located on the side of the upper box.

The air inlet is at the bottom of the lower box. After the flue gas flow enters, it fully contacts with the cloth bag. After purification, the air flows upwards and flows out through the air outlet on the upper part of the upper box. Both the air inlet and the air outlet adopt the international smooth surface welding method. Lan, welded in the middle to ensure the airtightness of the equipment.

The above-mentioned cloth bag is placed in the upper box, and a plurality of uniform pores are arranged on the bag to form a filter bag; the filter bag includes a plurality of filters, and the plurality of filter bags are evenly distributed in the upper box.

The upper bag dust removal device also includes a climbing ladder 9, which is arranged on the side of the dust removal device and communicates with the upper box body and the upper box body railing. The ladder is welded to the guardrail on the top of the upper box, which is convenient for maintenance personnel to safely go up and down to perform internal maintenance, replace cloth bags, etc.

The cloth bag is a water-repellent and oil-proof cloth bag with uniform pores, high dust removal efficiency, dust spraying and dust removal, and the pulse action of the electromagnetic valve, which greatly enhances the dust removal effect, makes the filter bag not easy to block, and prolongs the service life.

Although the embodiments disclosed in the present utility model are as above, the content described is only an embodiment adopted for the convenience of understanding the present utility model, and is not intended to limit the present utility model. Anyone skilled in the technical field to which the utility model belongs can make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in the utility model, but the patent of the utility model The scope of protection must still be based on the scope defined in the appended claims.
