The boiler exit gas is generally at a relatively high temperature. Therefore, when using a bag filter, the choice of cloth bag must be considered carefully. There are many kinds of dust bag, it can be divided into medium temperature, high temperature type according to temperature. In the high temperature dust bags, they are more famous in the case of Flumets and Metasbags. In the early stage of the development of bag filter, China did not have its own technology to produce high temperature bags, so most of them were purchased foreign products, so the dust removal equipment The price is high, but now the production and research of high-temperature dust bag has reached a mature field in China's technology, and the high-temperature cloth bags produced by many companies in China have been exported and exported to overseas markets.
Meytas Dust Bags and Flumez Dust Filter Bags are the two most popular cloth bags in Chunhui's high temperature cloth bags, and they are also two kinds of cloth bags with high temperature in the dust removal field. The main material of Metaxe bag is aromatic polyamide. Generally, its thickness is 2.2mm, the normal temperature can reach 204, the instant temperature can reach 250, and the temperature is comparable with Flumeths. Its grammage is 500g/m2, and Flumez is 800/m2.
In the field of bag type dust removal, the dust bag is usually compared to the heart of the equipment. The dust gas that can be handled by the bag filter mainly depends on the condition of the chemical fiber used to make the bag. Under normal temperature conditions, The bag can withstand temperature of 150 degrees. Under such working conditions, the filter media consisting mainly of polyester needle felt at room temperature, 729, 208, and acrylic fiber can basically meet their requirements.
In industries where the temperature of flue gas is relatively high, chemical fibers that can withstand high temperatures are required to produce filter media, so that they can fully meet the high-temperature working conditions of 150-260. Because of the aromatic polyamide fiber that Mettles fiber belongs to, Has good heat resistance, wear resistance, folding resistance, its folding performance is glass fiber can not be replaced.
It is said that it is made of two or more kinds of high-temperature resistant fibers mixed and stratified compound needles, and has a three-dimensional pore high temperature and high efficiency filter material. The bag has the advantages of high temperature resistance, ACID and alkali corrosion resistance, abrasion resistance, anti-folding, etc., after different surface chemical treatment and finishing technology, and has the characteristics of easy cleaning, water repellent and oil repellent, etc. Compared with its abrasion resistance, flexural resistance and peeling performance, the pricking felt can obviously improve and can take high air volume and high concentration of dust trapping. Compared with other synthetic fiber filter materials, it overcomes the elongation of other chemical fibers. Large, low temperature resistance and other characteristics.
In addition to the aromatic polyamides, the materials used in Flumets bags are also made of alkali-free glass fiber chopped strands. Its post-treatment method is also different from that of Metase. It is impregnated with PTFE, dried, covered, Waterproof, and Meytas is singed, calendered, covered, waterproof.
Acids exist universally in our life. There are both numerous kinds of natural acid compounds with biological functions and massive synthesized acids which are used in many ways.
In industry
Acids are fundamental reagents in treating almost all processes in today's industry. In the chemical industry, acids react in neutralization reactions to produce salts. For example, nitric acid reacts with ammonia to produce ammonium nitrate, a fertilizer. Additionally, carboxylic acids can be esterified with alcohols, to produce esters. Acids are often used to remove rust and other corrosion from metals in a process known as pickling. They may be used as an electrolyte in a wet cell battery, such as sulfuric acid in a car battery.
In food
Many acids can be found in various kinds of food as additives, as they alter their taste and serve as preservatives. Phosphoric acid, for example, is a component of cola drinks. Acetic Acid is used in day-to-day life as vinegar. Citric Acid is used as a preservative in sauces and pickles. Certain acids are used as drugs. Acetylsalicylic acid (Aspirin) is used as a pain killer and for bringing down fevers.
Acid catalysis
Acids are used as catalysts in industrial and organic chemistry; for example, sulfuric acid is used in very large quantities in the alkylation process to produce gasoline. Some acids, such as sulfuric, phosphoric, and hydrochloric acids, also effect dehydration and condensation reactions. In biochemistry, many enzymes employ acid catalysis.
