FRP desulfurization tower


Huaqiang glass fiber reinforced plastic desulfurization dust collector has the advantages of high efficiency, strong corrosion resistance, high strength, low noise, low power consumption, small size, convenient disassembly and maintenance, light and durable, and elegant appearance.

This product is made of glass fiber reinforced plastic and polyvinyl chloride. The outer surface of the tower uses water-resistant and aging-resistant gel coat resin as the anti-aging surface layer, and the thickness of the gel coat layer is not less than 0.5mm. The alkali-free, wax-free, and twist-free checkered gauze is used as the weather-resistant transition layer between the strength and the inner and outer surfaces. The resin content is not less than 75%. The number of layers is laid according to large and technical standards. The resin content is 60-70% To make the tower's strength absolutely reliable. As a high-efficiency dust removal equipment, FRP desulfurization dust collector has very high-quality industrial dust removal effect. Selection according to the dust concentration of the dust collector gas; for Zhangli, inertia and cyclone dust collector.

Generally speaking, the greater the dust concentration in the inlet, the higher the dust removal efficiency. However, this will increase the dust concentration in the outlet. Therefore, we cannot generally assume that the dust treatment effect is good only from the high dust removal efficiency. For wet-type dust collectors such as scrubbers, the initial dust concentration is preferably less than 10g / m; for bag dust collectors, the lower the dust concentration, the better the removal performance, at a higher initial concentration. With continuous ash cleaning, pressure loss and discharge concentration can also meet environmental protection requirements.

The initial concentration of the electrostatic precipitator is below 30g / m3, and it can be used without a pre-precipitator. The dust resistance of the dust collector should be in the range of 104 ~ 10nΩ · cm. The specific resistance of dust varies greatly with the temperature and humidity of the dust-containing gas. For the same kind of dust, the specific resistance is the largest between 100 and 200 ° C. If the dust-containing gas is sulfurized and tempered, the specific resistance will be reduced. Therefore, when selecting an electrostatic precipitator, it is necessary to grasp the specific resistance of the dust in advance, and fully consider the choice of the temperature of the dust-containing gas and the adjustment of the properties of the dust-containing gas. Influence of the temperature of dust-containing gas on selection 'Dry-type dust removal equipment must in principle be carried out at a temperature above the dew point of the dust-containing gas. In wet dust collectors, due to water evaporation and condensation after being discharged to the atmosphere, it should be treated at as low a temperature as possible. In the filter cartridge dust collector, the temperature for directly or indirectly processing the dust-containing gas should be lower than the heat resistance temperature of the filter cloth. The operating temperature of glass fiber filter cloth is generally below 260 ° C. Other filter cloths are between 80 and 200 ° C. In the electrostatic precipitator, the use temperature can reach 400 ℃. The specific resistance of the dust and the thermal expansion of the dust collector structure must be considered to select the temperature for processing the dust-containing gas. Selecting the dust dispersion according to the dust dispersion and density has a great impact on the performance of the dust collector, and the dust dispersion is the same, due to different operating conditions. Therefore, when choosing the type of dust collector, the first thing is to accurately grasp the dispersion degree of the dust. For example, when the particle size is more than 10υm, a cyclone dust collector can be selected.

In the case of particle diameters of several microns or less, electrostatic precipitators and bag precipitators should be selected. For specific selection, you can make a preliminary selection based on the degree of dispersion and other requirements by referring to the common types of dust collectors and performance tables. The type and performance of the dust collector introduced are determined. Dust density also has a great impact on the dust removal performance of the dust collector. The most obvious manifestations of this effect are gravity, inertial and centrifugal precipitators. A common feature of all dust collectors is that the smaller the bulk density, the more difficult the separation and capture of dust particles, and the more serious the second fly of dust, so special measures should be taken in operation and equipment structure. Precautions when using wet dust collector; most of the wet dust collector is water. If the size of the dust source equipment is small, it is necessary to remove harmful gases at the same time, or when it is necessary to completely capture extremely fine carbon black, lead dust and other dust, a wet dust collector is often used. Sewage treatment should be considered in the selection of wet dust collectors to prevent secondary pollution.

In addition, in order to effectively use the dust collector, it should be handled according to the situation. When handling carbon monoxide-containing flue gas, there should be measures to prevent explosion, such as introducing air into the high temperature part of the flue at the outlet of the furnace to oxidize carbon monoxide to carbon dioxide. Impact of dust collector dust selection on type selection 'The adhesion mechanism of dust and wall surface has a great relationship with the specific surface area and moisture content of dust. The smaller the dust particle size d, the larger the specific surface area, the greater the water content, and the greater its adhesion. In the cyclone dust collector, the dust adheres to the wall due to centrifugal force, and there is a risk of clogging. The dust adhered to the bag dust collector can easily block the passage of the filter bag, and the electrostatic precipitator can easily cause the discharge electrode and the dust collector Dust accumulation.

Type selection according to the amount of gas handled by the dust collector; the amount of gas handled by the dust collector is the decisive factor in determining the size and type of the dust collector. For the amount of air, you must choose a dust collector that can handle large volumes of gas. It is often uneconomical to use filters in parallel; it is most economical to compare the type of dust collector with the smaller gas volume, and it is the easiest to meet the environmental requirements of dust source control and dust emission. After the dust collector enters the actual operation. Affected by operating and environmental conditions are sometimes difficult to predict. Therefore, when determining the capacity of the device, you must ensure a certain margin or reserve some space that may increase the device.
