Float valve is one of the tray structures widely used in China at present. It has outstanding excellent performance, and its main characteristics are: Strip Guide Float Valve,Stainless Steel Float Valves,Acid Resistant Steel Float Valve,Strip Guided Float Valve Kit Yangzhou Tongyang Chemical Equipment Co., Ltd. , https://www.tongyangchemic.com
In iron and steel enterprises, dust pollution caused by the accumulation of raw fuel not only harms the environment, but also causes a large amount of powdered materials to be lost to the wind. According to a technician of a beneficiation plant, the annual iron ore fines blown away by wind can amount to 10,000 tons. A few days ago, the author learned from the dust removal project owner that a total investment of 15 million yuan in the dust removal project in the beneficiation plant area requires a total of 99 piles in the north and west sides. There are currently 90 completed piles, and the corresponding steel structures are in order. Advance. The reconstruction of dust removal and desulphurization in the area of ​​a thermal power plant with an investment of about 75 million yuan is in full swing. Invested 35 million yuan in coking coal on the 9th and 10th coke ovens, and coke-removing and dust-removing civil engineering concrete was partially completed, and steel structures and pipelines were being manufactured and installed. At the same time, an additional dust-proofing network project is being carried out at the raw material yards such as the iron and steel complex comprehensive stockyards and material companies. Talking about the company's dust-removal project, which is beneficial to the people and the people, Sun Jimin, the engineer responsible for the construction of the dust prevention network of the ore-dressing plant, said with excitement: “If the dust network of the raw material system is built well, the surrounding environment will be greatly improved and the original fuel loss will be greatly reduced. cut back."
The construction of Baosteel Nanqiao Approach Bridge was started on July 18th. It was completed on the eve of National Day and officially opened to traffic. In the past, due to the indentation between the approach bridge and the road, the workers passed the ice and snow days, and even if they were careful, they often slipped. During the rainy days, the water in the pits often splashed with water. The construction workers changed their level by filling slopes, diverting trucks, and dust protection. The commuters and workers were bid farewell to the trouble of “a sunny day covered with ash and a mud in rainy weatherâ€.
Nowadays, in the Baotou Steel Plant area, a wide, flat and tidy road, with a full range of road facilities and green trees and flowers is in sight. In recent years, the company has invested a large amount of manpower and material resources in building "Green Baotou Steel." This year, the company planted a total of 128,000 trees, an additional greening area of ​​367,000 square meters, and the plant green coverage rate reached 34%.
â‘´ Large operating flexibility
As the valve plate can rise and fall freely, it can adapt to the change of air volume from big to small, and the air gap speed is almost constant. It can also maintain high separation efficiency in a wide operating range with frequent load changes.
⑵ High separation efficiency
In practical application, the tray efficiency can reach 60~70%, 10~15 higher than that of bubble cap tray, and it is still very high at low load. Due to the high efficiency, the product quality is improved accordingly.
(3) Large processing capacity
Because the arrangement of float valves is much more compact than that of bubble cap tower, the opening rate is increased. In addition, the air flow blows into the liquid level in the horizontal direction, so the entrainment of foam is low, which can improve the air flow and increase the production capacity. The production capacity is 20~40% higher than that of bubble cap tower.
(4) Pressure drop is small
The air flow through the float valve shrinks, expands and turns only once, and the pressure drop is lower than that of the bubble cap tray. The pressure drop of each tray in the atmospheric tower is only 3-5 mm Hg.
In addition, it has simple structure and low cost; Long service life, no fear of dirty materials; Convenient installation and use.
Performance characteristics of float valve tray:
(1) The processing capacity is smaller than tongue type, sieve plate, and larger than bubble cap tray;
(2) Large operational flexibility;
(3) The pressure drop of the dry plate is larger than that of the tongue type, the sieve plate tray is larger, the pressure drop is smaller than that of the bubble cap tray, and the liquid level gradient on the tray is smaller;
(4) The entrainment of fog is small;
(5) Simple structure and convenient installation.
Invested more than RMB 160 million to carry out dust removal and transformation on concentrators, material companies, ironworks, coking plants, etc.; invested 48 million yuan for plant greening and road reconstruction; and invested 3 million yuan for the reconstruction of Nanqiao approach bridge. This is one of 10 good things that Baosteel promised to do for employees in 2008. At present, the bridge reconstruction project of Nanqiao is over and the rest of the project is nearing completion.
