The size of the bag pulse valve depends on the diameter D and length L of the filter bags used as well as the arrangement of the filter bags. First, calculate the filtration area of the bag pulse valve, and then determine the number of filter bags based on the filtration area, on-site height and other conditions. The size of the bag pulse valve is determined comprehensively in combination with the form of the air inlet.

I. Calculation Method of the Filtration Area of bag pulse valve:

Given that the flue gas volume of the boiler is Q(m^3/h) and the filtration air velocity is v(m/min), the required filtration area of the stainless steel dust collector can be calculated as: S=Q/ (60* v). For example: filtration area = Air volume /(60* filtration air velocity). A dust collector is a device that separates dust from flue gas. The performance of a dust collector is expressed by the volume of gas it can handle, the resistance loss of gas passing through the dust collector, and the dust removal efficiency. At the same time, the price of the dust collector, operation and maintenance costs, the length of its service life, and the difficulty of operation and management are also important factors to consider in its performance. Dust collectors are commonly used facilities in boilers and industrial production.

Example: Air volume 10,000 m ³ /h; Filtration air velocity: 2m/min; Filtration area = 10,000 /(60*2)=83.3 square meters.

Second, after calculating the total filtration area, the overall scale and size of the bag pulse valve can be determined. The single-machine dust collector is specially designed for the top and bottom of cement plant silos. Designed for belt conveyor and dust removal from local dust sources. It can also be used for dust removal from local dust sources in other industries. It has the advantages of small volume, large air handling capacity, compact structure, convenient and reliable use. According to the height and width limitations of our site, we will manufacture equipment of appropriate sizes.

Iii. The size of the bag pulse valve depends on the diameter D and length L of the filter bags used as well as the arrangement of the filter bags. Now let's take a look at the determination of the diameter and length of the filter bags.

The area of the filter bag (perimeter X height + cross-sectional area of the filter bag)= the actual filtration area. In commonly used pulse dust collectors, the diameter is generally 120 or 130mm. The length of the dust removal bags, under the condition that the filtration area and the diameter of the dust removal bags are the same, increasing the length can reduce the number of filter bags, thereby reducing the occupied area, reducing the components such as solenoid valves, pulse valves, and blow pipes in the dust cleaning system, saving investment, and also shortening the dust cleaning cycle. On the other hand, when the filter bag is lengthened, the box of the bag pulse valve also needs to be extended upwards, and the strength of its components has to be increased, which raises the equipment cost.

Fourth, when the diameter D and length L of the filter bags are selected, the number N of filter bags can be calculated. Dust removal equipment is the device that separates dust from flue gas, also known as a dust collector or dust removal device. Dust removal equipment utilizes the underground dust removal water pipes and compressed air pipelines. By adding certain additives to the water and introducing air pressure, a series of technological processes are completed through dedicated equipment to generate foam, which is then sprayed onto the dust source through distributors and nozzle bracket assemblies.

Calculation formula: N=S/ (D*D*3.1415926*0.25*L)

Then arrange the filter bags according to the N arrangement. After that, combine the inlet and outlet forms of the dust collector and determine the size (length, width, height) of the bag pulse valve. The size of the bag pulse valve depends on the diameter D and length L of the filter bags used as well as the arrangement of the filter bags. First, calculate the filtration area of the bag pulse valve, and then determine the number of filter bags based on the filtration area, on-site height and other conditions. The size of the bag pulse valve is determined comprehensively in combination with the form of the air inlet.

Whether the bag pulse valve is sturdy and durable is a matter of great concern for every application enterprise. Then, how can we ensure that the actual application effect of the bag pulse valve is excellent? The following maintenance methods can be emulated by application enterprises.

1. bag pulse Valves come in a wide variety of types, with different models, specifications, structural features and functional characteristics. Before application, it is essential to read the user manual of the article carefully to prevent damage to the dust removal equipment and endanger the safety of the user due to incorrect operation.

2. The application working temperature of the bag pulse valve should not exceed 40 degrees. The working site should not be at an altitude of about 1000 meters. It should be used in a well-ventilated environment with no flammable or corrosive gases in a dry room.

3. The bag filter is not allowed to absorb moisture. If the area to be cleared has large paper balls, plastic films or waste that exceeds the size of plastic straws, they should be removed in advance; otherwise, it is very likely to cause the plastic straws to be blocked.
