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
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.
LED use in the general lighting market will continue to rise
General lighting demand will continue to maintain strong growth In the long run, LED usage in the general lighting market will continue to rise, so LED demand will remain strong for a long time. It is expected that the demand for high-brightness LED will increase by 32% in 2014 and 19.% in 2015. The most strong growth will be general lighting, and we expect demand area in this area to increase by 71%. Therefore, we expect 2014 In the year, global general-purpose lighting LEDs will account for 43% of total demand, higher than 2013's 33. It is expected that the demand for TV/laptop/display backlight module (BLU) will drop by 2/16/8 in 2014. However, we expect tablet backlighting Module demand will increase by 32% year-on-year. Overall, we expect the total demand area of ​​backlight modules to increase by 11. 11. Several factors driving the development of LED general lighting market We believe that LED lighting demand will continue to grow strongly in 2014, the main driving factor There are: consumers' energy-saving and environmental awareness are enhanced, and LEDs are favored. Today, don't say that urban consumers, even rural consumers, mostly know the benefits of LEDs and start using LEDs to varying degrees. Therefore, the popularity of LEDs has been greatly improved. The decline in the price of LED products has made consumers' enthusiasm for buying fast, and they are no longer hesitant because of the price. In the last two years, LED light source products have dropped by 300, which has quickly narrowed the distance from the market. The relevant government departments have strongly supported, and financial subsidies and other policy support have accelerated market incubation. The vigorous promotion of the media has made LED products more and more popular. Experts, associations, and the media have promoted and promoted LEDs in large numbers to make them known to women and children. In addition to residential lighting needs, the analysis believes that outdoor lighting and commercial lighting will continue to grow steadily, driven by government projects and incentives. The continued decline in bulb prices revealed that LED bulb prices continued to fall in 2014, mainly due to cost reductions and lighting companies' promotional plans. Lighting companies and retail channels will also expand their market share through lower-cost LED bulbs with new technologies. For example, after Cree passed the ENERGY STAR certification, Philips also launched ENERGY STAR-certified products that enable consumers to purchase Philips LED bulbs for subsidies. We expect LED bulb demand to grow steadily after the retail price of LED bulbs equivalent to 60 watts (700-900 lumens) of ordinary bulbs has fallen below $10. But bulbs will not become mainstream products in urban home improvement. Product quality continues to improve and design is improved. It has been observed from the show that product quality continues to improve and the number of omnidirectional bulbs is increasing. Our survey also shows that the cost of LED light sources has dropped to around 40-45 total operating costs. Thermally divergent materials have also changed. As LED energy efficiency increases, the industry uses more plastic materials to reduce heat generation.
