The application of fillers in water treatment, how many types of fillers are there?

Fillers generally refer to materials that are filled in other objects. In chemical engineering, packing refers to inert solid materials installed in packed towers, such as Pall rings and Raschig rings, etc., whose function is to increase the gas-liquid contact surface and make them mix strongly with each other. In chemical products, fillers, also known as fillers, refer to solid materials used to improve processability, mechanical properties of products and/or reduce costs. In the field of sewage treatment, it is mainly used in the contact oxidation process, and microorganisms will accumulate on the surface of the filler to increase the surface contact with the sewage and degrade the sewage.

Under what circumstances can the lithium oxygen molecular sieve meet the standard?

A synthetic hydrated aluminosilicate (zeolite) or natural zeolite with the function of screening molecules. Its general chemical formula is (M'2M)O·Al2O3·xSiO2·yH2O, and M' and M are monovalent and divalent cations such as K+, Na+, Ca2+, Ba2+, etc. respectively. It has many channels with uniform pore size and neatly arranged pores in its structure, and molecular sieves with different pore sizes separate molecules of different sizes and shapes. According to the different molecular ratios of SiO2 and Al2O3, molecular sieves with different pore sizes are obtained. Its models are: 3A (potassium A type), 4A (sodium A type), 5A (calcium A type), 10Z (calcium Z type), 13Z (sodium Z type), Y (sodium Y type), sodium mordenite type Wait. It has high adsorption capacity, strong selectivity and high temperature resistance. It is widely used in organic chemical industry and petrochemical industry, and it is also an excellent adsorbent for gas dehydration. It has also received increasing attention on exhaust gas purification.

Use of Deodorant Mesh Fillers

The deodorant grid filler produces a large number of living organisms in intensive farms. Therefore, the odor generated is not only large in gas volume but also complex in composition. According to research, there are more than 200 kinds of odor components in pig manure, among which the largest odor is It is NH3, H2S and VFA (volatile fatty acid), these harmful gases not only harm people's physical and mental health, but also have a serious impact on the growth of aquaculture organisms, which can easily cause irritability, decrease in feed intake, and physical changes in cultured organisms. Weak, or even induce the risk of respiratory disease, death, etc., in addition to the "Environmental Impact Assessment Law"

The role of wire mesh demister for oil-water separation

There are many kinds of oil-water separators. The principle is that oil and water are incompatible, and the density of the oil is small to separate. Of course, this separation is not complete, and there may be small oil droplets in the water. For oil absorption, the commonly used dissolved oil is carbon tetrachloride, which is denser than water. When passing through water, the residual oil in the water can be absorbed. This process is called extraction.

One-time forming Pall ring, their production process has those

Metal Pall ring packing is widely used in chemical industry and other industries. To be used for medium separation, it is an improvement on the basis of Raschig ring. Two rows of windows with inwardly extending tongues are opened on the ring wall, and each layer of window holes has 5 A tongue, this type of configuration improves the distribution of gas and liquid, making full use of the inner surface of the ring. In the prior art, the manufacture of stainless steel Pall rings requires three processes, namely material cutting, bending and rounding, which requires at least two sets of molds, which affects production efficiency and does not use human and material resources reasonably.

Ceramic random packing in packed tower has those advantages

There are many kinds of chemical fillers. At present, the most used tower fillers in industrial production are ceramic fillers, including ceramic structured fillers and ceramic bulk fillers: Today we will briefly introduce ceramic bulk fillers:
