Dust Collector | Dust Collector | Technical Information

The elements of the bag sprayer's pulse spraying are the spraying pressure, the spraying cycle and the spraying time. In the case where the diameter of the electromagnetic pulse valve, the venturi tube structure, the diameter and number of injection holes, and the diameter and length of the filter bag in the injection mechanism have been determined, the three factors of injection are the main factors affecting the performance of the dust collector. In design selection and actual operation, handling the relationship between the three is the key to ensure the normal operation of the dust collector.
Bag dust collectors in steel plants have a wide range of applications, and have been widely used in electric furnace steelmaking, blast furnace coal injection, sintering, refractory, carbon black, cement and other industries, and have achieved good results. Bag dust collectors in steel mills have good advantages. Compared with other similar products, their dust removal capacity and filtration load are very strong. The bag filter in the steel factory is a new type of high-efficiency bag filter which is improved on the basis of summarizing the current domestic non-standard bag filter for blast furnace gas purification. It can also be used in other flammable and explosive gas purification systems operating under positive pressure. . The structure of the steel factory bag dust collector is welded integrally, and the box body, air inlet and outlet pipe, ash hopper, and discharge pipe are integrated.
The maintenance of the electrostatic precipitator mainly includes the following: regular lubrication of the lubricating parts and the transformer; exposed metal parts such as platforms, ladders, railings and other parts are regularly painted to prevent rusting; reserve vulnerable parts, etc .; The electrostatic precipitator should always operate the rapping mechanism to prevent rusting and the shaft system to be stuck.
Stand-alone pulse dust removal equipment is the most commonly used dust collector. This dust collector has a small footprint, a large air volume, and a good dust removal effect, so it has won the favor of customers. Although this dust collector won the customer's favorite, the customer did not understand the detailed technical parameters and three-dimensional drawing of this equipment. In response to this situation. Wo Nuo and environmental protection professional and technical personnel produced the three-dimensional drawing and detailed technical parameters of this dust removal equipment. This picture gives everyone a glance.
VOCs (volatile organic compounds) mainly include benzene, toluene, xylene, styrene, trichloroethylene, chloroform, trichloroethane, diisocyanate (TDI), diisocyanatolate, etc. Saturated hydrocarbons (such as butadiene, styrene), nitrides (such as ammonia, methylamine, skatole), sulfides (such as hydrogen sulfide, methyl sulfide), chlorohydrocarbons (such as chloroform), oxygenated hydrocarbons (such as Acetone), plant essential oils (such as camphor oil) and other compounds.
VOC waste gas treatment mainly treats volatile organic compounds. The VOCs referred to in this method are collectively referred to as volatile organic compounds under specific conditions. Volatile organic compounds mainly include non-methane total hydrocarbons (wan hydrocarbons (ting), olefins, alkynes, aromatic hydrocarbons), oxygen-containing organic compounds (aldehyde (quan, ketone (tomg), alcohol ( chun), ethers, etc.), halogen (lu) hydrocarbons, nitrogen-containing compounds, sulfur-containing compounds, and the like.
At present, the market for odor-removing equipment is very hot. Check it online. The odor-removing equipment is also diversified. There are low-temperature plasma equipment, photocatalytic equipment, and plasma photo-oxygen integrated machines. As for the variety of varieties, customers do not know which equipment to remove odor is more suitable for their own working conditions. For these questions, Novo environmental protection professional and technical personnel can give you a satisfactory answer. The following Novo and Xiaobian are specifically to do a detailed analysis of the operating conditions of the plasma photo-oxygen integrated machine in the end.
We all know that the dust removal industry is a very hot industry today, and the bag dust collector is a widely used dust removal equipment in the dust removal industry. So what issues should be considered in the design of the bag dust collector? Let me introduce it to everyone:
The dust removal bag must be combined with corresponding accessories to maintain the shape suitable for filtering and cleaning during the filtering and cleaning process, to achieve the purpose of filtering or peeling off the dust particles, and to keep the dust collector in a normal operating state. The combination of filter bag and accessories is called the filter unit.
Now many bag dust collectors are undergoing renovation, but many companies do not know what the specific standards are. The specific standard set by the state is 30 mg / m3, but many companies define it at 15 mg / m3. It is the test put forward by our company that makes bag dust collectors. So how can we achieve this standard? Based on many years of experience, we must pay attention to the following points:
It is difficult to treat a gas containing only tar mist with a bag filter, but it can be filtered when the oil mist in the gas is small and the dust content is quite large. For example, in the asphalt concrete plant, the flue gas of the stone dryer, plus the dust from the conveyor and other exhaust gases, all enter the bag filter, and in addition. At the mixer and unload the finished product. The tar mist produced by the heated asphalt concrete also entered the bag filter. In this case, the amount of dust accumulated on the filter cloth far exceeds the amount of oil mist, which can prevent the trouble of oil mist sticking and ensure the stable operation of the bag filter in the manufacture of electrodes and molded carbon products. ,
People often say when buying glass fiber dust-removing cloth bags, I want to cover the filter material, but there is a lot of knowledge in the fiber-glass dust-removing bag filter material coating. Which glass fiber coating method is more scientific and more Durable yet. I am afraid this is not known to professionals. For this knowledge point. My promise and Xiao Zhao will tell you in detail the types of glass fiber coatings, which are more scientific and more durable.
The dust collector is mainly composed of an upper box body, a middle box body, an ash hopper, an air inlet equalizing pipe, a support filter bag, an injection device, and an ash discharge device. Dust-containing gas enters the ash hopper of each compartment from the air inlet equalizing pipe of the precipitator, and under the guidance of the ash guide device, large particles of dust are separated and directly fall into the ash hopper, while the finer dust enters evenly The middle box is adsorbed on the outer surface of the filter bag, and the clean gas passes through the filter bag and enters the upper box, and is discharged into the atmosphere through the off-line valves and exhaust pipes. With the progress of the filtering conditions, the dust on the filter bag accumulates more and more. When the equipment resistance reaches a limited resistance value (generally set to 1500Pa), the dust cleaning control device sets the differential pressure or the dust cleaning time. After the set value automatically closes the one-line offline valve,
The dust collector is modified while keeping the original casing, including retaining the first electric field and the inlet and outlet gas horns, the gas distribution plate, the lower ash hopper, and the ash exhaust zipper.
The dust existing in the atmosphere includes sand, pollen, and other dust produced by natural phenomena, and man-made dust, such as smoke and powder. Although naturally generated dust accounts for a large proportion in the atmosphere, the main impact on environmental pollution is man-made dust. In order to protect the environment, the state has dust emission standards. Screening, tabletting and other processes are prone to generate a large amount of dust, so dust removal and dust prevention measures must be adopted to strengthen labor protection, strengthen safety production and dust recovery to ensure quality and so on.
