Single-machine pulse dust collector adopts pulse injection on-line dust removal method.

　　Single-machine pulse dust collector adopts pulse injection on-line dust removal method. The ash cleaning process is automatically controlled by the pulse controller, and the user can use the time control method to clean the ash as needed. A plurality of filter cartridges are arranged in the dust collector to increase its effective filtering area. When a certain (pair of) filter cartridges meet the requirements set for dust removal, the blowing device is started for dust removal, and the other filter cartridges work normally, so that the dust removal effect is achieved without affecting the operation of the equipment, and the dust collector can run continuously.

　　At present, single pulse dust collector is mainly used in the following occasions: chemical industry, medicine, steel mills, power plants, carbon, abrasives, wood, smelting, mechanical processing, powder recycling, grain processing, pharmaceutical production, food production, powder transportation, plasma cutting, welding dust, casting and other industries.

　　The filter bags of single pulse dust collector are arranged in a straight line, and each row of filter bags is equipped with a pulse valve to control the pulse cleaning of compressed air. The action of the pulse valve is controlled by a pulse controller. During ash cleaning, the ash cleaning controller issues an instruction to make the pulse valve release 0.5-0.7MPa of compressed air at the moment of action. Compressed air rushes into the filter bag at a high speed through the small hole on the blowpipe facing the filter bag, and at the same time, it induces a secondary air flow several times that of compressed air, thus generating an instantaneous shock wave and spreading downward along the whole length direction of the filter.

　　Generally, the selection of filter material for single pulse dust collector should comprehensively consider the properties of dust-bearing gas and dust, such as gas temperature, gas humidity, gas chemistry, dust adhesion, dust abrasion, particle size and flammability, etc., and combine the dust gas distribution ratio, dust cleaning method and installation method to reasonably select the filter material with temperature resistance, temperature resistance and so on. In addition, due to the high temperature of flue gas, the humidity of flue gas may increase when the emergency sprinkler system is started, and the hydrolysis resistance is also a factor to consider in selecting filter materials. Due to the different materials of filter media, their prices vary greatly, so the final choice is often the result of comprehensive comparison of one-time investment and operating cost and effect. The use temperature, dust removal efficiency, dust removal performance, cost and the degree of different chemical components in flue gas of different filter materials are different, so they need to be selected according to comprehensive technical and economic comparison.

　　Single pulse dust collector model:

　　There are mainly six kinds of dusters with 24 bags, 32 bags, 48 bags, 112 bags, 80 bags and 120 bags, but these six kinds of commonly used dusters may not meet the user's working conditions. We can also adjust the length, width and height of the dusters to ensure that the produced single-machine pulse dusters can be suitable for the user's working conditions.

　　Different models and prices of single-machine pulse dust collector are also different. The price of raw materials for single-machine pulse dust collector is rising constantly, and the price of steel is changing all the time. The company has been ensuring the quality of products, and many users only regard the price of dust collector as the only standard for purchasing dust collectors. In fact, this is not correct. Here are some tips for purchasing single-machine pulse dust collectors.

　　Skills of purchasing single pulse dust collector;

　　1. Choose a regular manufacturer

　　When choosing a single pulse dust collector, we must choose a more formal manufacturer, which can not only ensure the quality of the single pulse dust collector, but also be cheaper in terms of the price of the single pulse dust collector.

　　2. Conduct on-the-spot investigation of manufacturers

　　When choosing a single pulse dust collector, you must choose a better purchasing channel, because now everyone will choose a faster way to buy a comparison chart, but this way of buying will make you buy a inferior single pulse dust collector.

　　Selection of single pulse dust collector

　　1. Selection of filtration speed The filtration speed is a key factor in the selection of dust collector, which should be determined according to the properties of smoke or dust, application occasions, dust particle size, viscosity, gas temperature, water content, dust concentration and different filter materials. When the dust particle size is fine, the temperature and humidity are high, the concentration is high, and the viscosity is high, the low value should be selected. Such as s1m/min；; On the other hand, a high value can be selected, which generally should not exceed 1.5m/min. For dust with large particle size, normal temperature, dryness, no viscosity and extremely low concentration, 1.5~2m/min can be selected. When selecting the filtration speed, it should be calculated that the net filtration wind speed should not exceed the above value when reducing the filtration area of the first room (when cleaning ash).

　　2. Filter materials should be considered according to the temperature, water content, acid and alkali properties, viscosity, concentration and grindability of dust. Generally, it is selected according to the temperature of dusty gas when the water content is small and there is no acidity. At room temperature or s130°C, 500~550g/m2 polyester needled felt is commonly used. When the temperature is less than 250°C, aramid Nomex needled felt or 800g/m2 glass fiber needled felt or 800g/m2 weft double glass fiber fabric or Flames [FMS] high-temperature filter material shall be selected (the fluorine-containing gas cannot be made of glass fiber). When the water content is high and the dust concentration is high, filter materials (or anti-condensation filter materials) or film-covered filter materials (the base cloth should be treated needled felt) should be selected. When the dusty gas contains acid and alkalinity and the gas temperature is s190°C, Ryton polyphenylene sulfide needled felt is often used. When the gas temperature is s240°C and the sexual requirements are not too high, P84 (polyimide) needled felt is selected. When the dust-containing gas is flammable and explosive, the dacron needled felt is selected, and when the dust-containing gas is both flammable and explosive, the dacron needled felt is selected.

　　3. Controller: The cleaning control of DMC pulse single-machine dust collector adopts PLC microcomputer program controller, which is divided into three control modes: constant pressure (automatic), timing (automatic) and manual. Constant pressure control: control according to the set pressure difference. If the pressure difference of the dust collector exceeds the set value, each room will be cleaned automatically in turn. Timing control: according to the set time, every other cleaning cycle, each room is cleaned in turn. Manual control: In the on-site operation cabinet, you can manually control each room to automatically clean the ash once in turn, or you can clean each room separately. The control mode is selected by the user, and when there is no requirement from the user, the supply is controlled at regular intervals.
