Four tips to prevent the dust bag from being damaged2018 / 10/31 13:13:55
Venturi tubes are provided at the positions of the dust removal frame. In this way, even if the blowing holes of the bag dust collector are distorted, the blowing air stream will not directly blow onto the bag. This air stream will be blown onto the venturi tube and then returned to the bottom of the skeleton. This venturi tube serves as a protective dust bag and guides the wind.
The selection of the filtering wind speed in the dust collector has a direct relationship with these three factors: 1. Selection of dust filtering bag filter materials: The filter materials at normal temperature dust filtering bags are relatively thin, so the resistance of the dust filtering bag is relatively small, so the filtering wind speed can be relatively high. Speak higher. Generally, it is 1.0-1.5m / min. The filter material in the high-temperature dust bag is thicker, and the resistance of the dust bag is greater, so the internal filtering wind speed of the dust collector is lower, so that the dust bag can collect dust well. Dust collection. Generally it should be controlled below 0.8m / min.
In all aspects of the printing process, improper process treatment will cause environmental pollution problems, which will adversely affect the human body and the environment. This is mainly manifested in organic compounds emitted by solvent inks during drying and isopropyl alcohol in alcohol wet liquid , The hot-melt adhesive used in wireless binding, the volatile gas of glazing paint, etc. all cause pollution to the air and are harmful to human health.
The spray tower has low maintenance cost and good use effect. After using the spray tower for a period of time, there will always be some small problems. What are the causes of these problems, and how should we solve them, this is the concern of customers. Xiao Zhao will give you a detailed analysis and explanation.
Cyclone dust collector is a kind of dust removal equipment, which is generally used in pre-dust collection and cooling conditions. When buying cyclones, people often see two types of cyclones, namely stubby cyclones and slender cyclones. Both types of cyclones have their own functions, but they are only effective. It's different, it's different to adapt to working conditions. Let's talk about how these two cyclone dust collectors should be selected and their application conditions and use effects for comparison.
The current distribution plate is also called distribution plate. Distribution plate is generally used in electrostatic precipitators. This accessory is not available on the bag filter. Here we introduce the precautions for making the current collector plate of this electrostatic precipitator:
The unloader is one of the most common accessories in the dust collector equipment, and its main function is to perform a uniform discharge function. Although this function sounds simple, the requirements for a good unloader to be successful are very strict. E.g:
The dust removal system of the mixed iron furnace includes the exhaust hood, pipes, dust collectors, fans, chimney hoods, and the determination of the exhaust air volume at the mouth of the hood is the determinant of the smoke collection efficiency of the exhaust hood.
The discharge system of industrial dust removal equipment is relatively wide and diverse, and the discharge tools should be selected according to the specific requirements of customers. There are several types of ash discharge devices below the ash hopper of the dust collector. Yes (manual flapper valve, pneumatic flapper valve, electric flapper valve, star discharger, electric air lock, weight flapper valve, pneumatic flapper valve, electric flapper valve).
The method of vibration dust cleaning uses mechanical equipment to beat or shake the structure of the hanging filter bag, so that the filter bag oscillates and clears the dust. Most of the round bags apply vibration on the top, so that it will oscillate straight or horizontally, maybe straight or horizontal The two directions oscillate together, and the direction in which the oscillation is applied is also in the middle of the filter bag. Because the dust must be raised during dust cleaning, the separation and dust removal system is often used to separate all the dust collectors into several bag rooms. The ash cleaning is performed sequentially from room to room, which can keep the continuous work of the dedusting equipment. The bag room for ash cleaning uses the valve to actively cut off the air flow to prevent dust-laden air from entering. Oscillating ash cleaning with the top as the main unit, every minute The vibration can reach hundreds of times to make the dust fall into the ash bucket.
Submerged and right-angle solenoid pulse valves use threaded connection methods, which require an appropriate amount of sealed raw material tape to be wound on the outer thread of the injection pipe. And cause difficulties in operation.
Under the circumstances that China's coal types are changeable and its operation is not standardized, the service life of filter bags for bag dust removal equipment is more than 20,000 hours. However, there have been examples of more than 30,000 hours of operation abroad. The service life of the filter bag is guaranteed to be 30,000 hours, which is selected in conjunction with 4a overhaul. How can the life of the dust removal equipment be longer and longer? Let's introduce the methods to extend the life of the bag dust removal equipment:
The dust bag was damaged around 40 cm. Main reasons 1. Compressed air that blows away the dust from the center of the bag and directly flushes the side wall of the bag. To avoid this problem, a Venturi tube can be equipped on the dust removal skeleton.
Botou Nuohe Environmental Protection Equipment Co., Ltd. designed a soft connection method at the connection between the dust outlet and the fan inlet when processing the bag dust collector in the wooden factory. There is a muffler to reduce the noise caused by the high-speed operation of the fan;
MC stand-alone bag filter is one of the small stand-alone dust collectors. This type of stand-alone bag filter is simple in structure, good in use and easy to operate, so it is widely used
