Some related introductions of welding dust removal equipment


Some related introductions of welding dust removal equipment, Dust removal equipment refers to the equipment that separates dust from flue gas, also known as dust collector.


(1) Harm of welding fumes to human body: Some toxic substances often appear in welding operations. For example, ethanol, isocyanate, abietic acid, hydrocarbons, nitrogen oxides, sulfides, etc. Floating in the air. It mainly invades the human liver, lungs, cardiovascular and blood through the respiratory tract. These toxic substances are being proven to devour human health. Will cause many occupational diseases. Such as eczema, bronchitis, respiratory infections, lung cancer, skin allergies, asthma, etc. If severe, it will disturb the central nervous system, destroy the digestive system, cause complications and fail to die.


(2) Impact of pneumoconiosis and lung function of electric welders: When welding an arc, the core, coating and metal substrate in the electrode will melt, evaporate, oxidize and agglomerate under the high temperature of the arc, generating a large amount of metal oxides and other substances Soot. If inhaled for a long time, it can cause welder pneumoconiosis.


(3) Manganese poisoning: various weldments and electrodes contain different amounts of manganese. Usually the manganese content in the core is low, only 0.3-0. about 6%. In order to improve the mechanical strength, wear resistance, corrosion resistance and other properties, the manganese content in hih using manganese-containing electrodes can be as high as 23%. If long-term inhalation of manganese-containing fumes, welding in poorly ventilated places such as cabins, boilers, closed containers, etc. may cause manganese poisoning. Bleeding and increased manganese in urine can be detected.

Some related introductions of welding smoke and dust removal equipment, the filter element can be made of cotton fiber, glass fiber or various chemical fibers through spinning (or needle punching) to make filter material, and then sewn into a vertical hanging filter bag. Different occasions should choose different filter material.. The dust collected on the filter bag deforms the filter bag to remove the dust by periodic mechanical vibration, back blow of filtered flue gas or pulse back blow of compressed air.


The flue gas that can pass through the filter bag and the filter cake (filter bed) on the surface of the filter material depends on the pressure difference between the two sides of the filter layer. This pressure difference is usually called the tube sheet pressure difference D. p. (sometimes referred to as bed differential pressure). In fly ash collection, a special parameter is the speed of filtering the flue gas-the amount of air filtered by each filter cloth per square meter. The filter bed pressure difference dp is linearly proportional to the flue gas flow rate and therefore linearly proportional to the flue gas flow rate.


This fixed scale factor is often called the filter resistance. According to this definition, filter resistance has nothing to do with flue gas flow, and is somewhat similar to the concept of resistance. We express the average filtration rate as Bubi-it is the ratio of the volume of smoke to the total filtration area (expressed in m3 / m2 / min). This parameter is a very important technical index in the selection and design of bag dust removal equipment.

The remaining pressure loss of the bag dust removal equipment is caused by the flue and baffle door between the inlet flanges of the bag dust removal equipment. The magnitude of this pressure drop is directly proportional to the square of the flow velocity of the flue gas, so the pressure drop δp of the entire baghouse dust removal equipment. The flue gas volume has a quadratic relationship with the flue gas volume.


Some related introductions of welding fume dedusting equipment. The performance of the dedusting equipment is the amount of gas that can be processed, the resistance loss when the gas passes through the dedusting equipment, and the dedusting efficiency. At the same time, the price of dust removal equipment, operation and maintenance costs, service life, and ease of operation and management are also important factors affecting the performance of dust removal equipment.


With the country's continuous attention to environmental protection, in order to adapt to the continuous changes of the market and meet the needs of different customers, we continue to optimize the product structure and introduce technical talents, so that the company continues to lead in the increasingly fierce competition.
