1、 Pulse bag filter measures require combustible substances and oxygen for combustion reactions, as well as an ignition source of energy. For dust explosions, three elements should be present: ignition source, combustible fine dust, and dust suspended in the air to form a dust cloud within the explosion concentration range. Only when these three elements coexist can an explosion occur. Therefore, as long as one of the conditions is met, the occurrence of an explosion can be prevented. Pulse bag filter; The following technical measures are commonly adopted in China. 1. The use of filter bags inside the pulse bag dust collector can generate static electricity due to the friction between dust and filter cloth during the flow process. The accumulation of static electricity can generate sparks and cause combustion. For the pulse cleaning method, the filter bag is made of polyester needle punched felt, which is prone to insufficient static electricity. Conductive metal wires or carbon fibers are spun into the filter bag fabric. When installing the filter bag, it is connected to the workshop grounding grid through a steel frame and porous plate, and then connected to the workshop grounding grid through the shell. There are various products that have been developed for anti blowing dust removal filter bags, and their usage effects are very good. 2. Equipment grounding measures: Pulse bag dust collectors are often arranged outdoors due to operational needs, even on tall steel structures. According to equipment grounding requirements, equipment grounding lightning protection has become a measure, but dust collectors generally do not have lightning rods. 3. To prevent the accumulation of combustible dust in the internal components of the pulse bag filter, all beams, partitions, etc. should be equipped with dust-proof plates, and the slope of the dust-proof plates should be less than 70 °. The slip angle of the ash hopper is greater than 70 °. In order to prevent dust accumulation due to the small angle between the two hopper walls, two adjacent side plates should be welded with slip plates to prevent dust deposition. Considering the occurrence of ash hopper condensation blockage due to abnormal operation and high dust humidity, when designing the ash hopper, steam pipe insulation or tubular electric heater should be added to the high-temperature dust collector on the ash hopper wall plate. To prevent material accumulation in the ash hopper, each ash hopper also needs to be equipped with a bin arm vibrator or air cannon. 4. Detection and fire prevention measures can be taken on the dust removal system to prevent potential hazards. (1) Firefighting facilities. There are mainly water, CO2, and inert fire extinguishing agents. For cement plants, CO2 is mainly used, while steel plants can use nitrogen. (2) Temperature detection. In order to alleviate the temperature changes of the dust collector and control the ignition point, several thermometers are usually installed at the inlet of the dust collector and on the ash hopper. (3) CO detection. For large pulse bag dust collectors, the installation of thermometers is limited due to their large volume, and sometimes combustion phenomena that occur far away from the thermometer measuring point are difficult to reflect from the thermometer. A CO detection device can be installed at the outlet of the dust collector to assist in detection. As long as combustion occurs anywhere inside the dust collector, the CO in the flue gas will increase. At this time, the alarm for the increase in CO concentration will be interlocked with the dust removal system control to stop the operation of the dust collector system in a timely manner. 2、 The future market demand trend of pulse bag dust collectors. The application range of pulse bag dust collectors is becoming more and more extensive. In order to complete the dust removal work of the equipment, pulse bag dust collector manufacturers have produced a pulse bag dust collector device. Now, let's talk in detail about the future market demand of pulse bag dust collectors. Due to the increasing awareness of environmental protection among people, many enterprises need to purchase dust removal equipment in their development. This shows that our pulse dust collector manufacturer has produced this product, which is deeply loved by consumers. When using the pulse bag dust collector, we do not remove dust as a function, and there are also functions of the pulse bag dust collector that can reduce the occurrence of accidents. Pulse bag dust collectors can be used in any environment without causing any damage to the surrounding environment, and can reduce manpower and material resources during transportation and handling. As a result, pulse bag dust collectors have gradually gained the trust of consumers in the market, and the number of people gradually applying them is also increasing. Therefore, we should not underestimate the future development of pulse bag dust collectors. The development prospects of pulse bag filter are still very promising, and the future market demand will definitely increase significantly. 3、 Measures to prevent Mars from entering the pulse bag filter: 1. Installing a Mars capture device on the pipeline is a simple and feasible method. Additionally, when Mars passes through the capture device, it can emit an electrical signal to trigger an alarm. At the same time, stop operating or change the gas circuit, etc. 2. Set up pre dust collectors and cooling pipelines. Because a cyclone dust collector is installed as a pre dust collector to capture coarse dust and sparks. Using this method, particles that are too fine are difficult to capture, and in most cases, the particulate dust can be burned off before entering the dust collector. Install cooling pipes after the pre dust collector and control the flow rate inside the pipes to keep it as low as possible. This is a comparative technical measure that allows the gas to have sufficient residence time inside the tube. 3. Cool down the spray tower. Gas cooling method of direct water spray in advance. The cooling water supply is controlled for the dusty gas inside the pulse bag filter. Most of the burning dust can be cooled upon contact with fine water droplets, but water droplets are prone to gasification. In order to cool the burning dust that has not yet come into contact with water droplets, there should be sufficient space and residence time. In case of any combination of spray tower, cooling pipe and pre dust remover, it can prevent sparks from mixing. 4、 Why are the prices of pulse bag dust collectors of the same model different? With the increasing severity of air pollution and the prevalence of haze in many places, the supervision of environmental protection requirements for enterprises is becoming increasingly strict. This makes it urgent for enterprises that do not meet environmental standards to replace pulse bag dust collectors. However, the quality of the environmental protection industry varies, and prices are not high and low. Customers often compare prices when choosing pulse bag dust collectors, but they are not very concerned about quality. Below, we will introduce the secret of why the prices of pulse bag dust collectors differ by several times for customers who choose to purchase them. The general configuration of a pulse bag dust collector includes the dust collector body, solenoid valve, dust bag, dust removal skeleton, cylinder, etc. Some manufacturers of pulse bag dust collectors will reduce costs in these configurations. The pulse bag dust collector body needs to be welded with 3-4 thick carbon steel, and then polished and painted in the later stage. However, many small workshops use inferior thin steel to make it, which reduces costs and makes the price much cheaper. This quality can be imagined!
