Why say closed cooling tower is energy saving and environmental protection equipment, more and more users are using this kind of equipment to replace the original equipment (open tower), we can through data analysis and comparison, the two energy data accounting can be obvious. Energy consumption is basically two major aspects, one is water, the other is electricity. Both are energy costs that no cooling tower can escape, unless you leave the equipment on.
First of all, look at the consumption of water. Water is generally consumed in two aspects. One is the flying overflow after spraying, and the other is the evaporation consumption of water.
Let's look at the open cooling tower, the spray water of the tower is basically between two and three percent of the overflow rate, if we according to the daily operation of 10 hours, excluding holidays, 280 days of operation. According to the actual open cooling tower flow of 6000 cubic meters per hour to calculate. 6000*2%*10*280= 336,000 tons of water, and the same closed cooling tower, its spray flying overflow is very small, because after all, the spray work is carried out in the tower, almost can be controlled in a few thousandths, we calculate according to 5 thousandths, the same is 10 hours of work, 280 days a year operation, To achieve the same cooling amplitude is basically 4,500 tons per hour of closed cooling tower is enough, then the calculation results: 4,500 *0.5%*10*280= 63,000 tons, it is not difficult to see, because of the different design structure caused by the waste of spraying water resources, more than 200,000 tons of terror. The bigger the pool of the open tower, the more wasted water, because the evaporation area increases, and the closed cooling tower has no pool, so the consumption here is zero. Judging from the price of a ton of water, just such a equipment, a year to solve the capital of hundreds of thousands of enterprises.
Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.
To sum up, for the closed cooling tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.

The 21st typhoon "Sally" and the 22nd typhoon "Hippo" landed in China with short time intervals and overlapping areas, which may bring adverse impacts on the production of agriculture (pastoral and fishery). To this end, the Ministry of Agriculture attaches great importance to the emergency deployment of Typhoon No. 21 "Sally Jia" and Typhoon "Hai Ma" typhoon defense work, and requires Hainan, Guangdong, Guangxi, Fujian, Yunnan and other provinces (regions) to strengthen the implementation of responsibility, Strengthen guidance services, implement defensive measures, and ensure the safety of agricultural production and people's lives and property.
[China Agricultural Machinery Industry News] According to the forecast of the Central Meteorological Observatory, the 21st typhoon "Sally Jia" will land on the coast of Hainan Qionghai to Sanya during the day on the 18th. The landing intensity is strong typhoon or super typhoon. The typhoon "Hippo" of the 22nd this year has been strengthened to a strong tropical storm class on the morning of the 16th. It is expected to gradually approach the coast of eastern Guangdong to the southern part of Fujian on the afternoon of the 20th.
There are two more typhoons coming to the Ministry of Agriculture for emergency deployment.
First, arrange deployment early. It is currently a critical period for the harvest of southern late rice and an important period for fishery production. The agricultural departments at all levels must adhere to the goal of stabilizing grain and increasing income, and based on the fight against disasters, earnestly take the prevention of Typhoon No. 21 "Salika" and Typhoon No. 22 "Hippo" as the current urgent task, and act quickly. Strengthen leadership, clarify responsibilities, deploy early, pay close attention to implementation, ensure that responsibilities are in place, measures are in place, and disaster losses are greatly reduced.
Second, strengthen monitoring and early warning. Strengthen consultations with relevant departments of meteorology, oceans, water conservancy and other departments, strengthen emergency duty, and keep a close eye on the movement path of Typhoon No. 21 "Sally Kay" and Typhoon No. 22 "Hippo", pay close attention to the development of disasters, make full use of broadcasting, TV, newspapers, mobile phones, Internet and other media, timely release of warning information and typhoon technical measures. Strengthen the disaster situation dispatch, collect, verify and reflect the disaster situation in time, ensure the smooth flow of information, and improve the timeliness and accuracy of information. The fishery department shall notify the fishing vessels and personnel in the relevant sea areas of the disaster warning information at the time, and timely report the preparations for the defensive measures such as the entry of the fishing boat, the withdrawal of the fishermen from the shore, and the standby of the fishery vessels. Further improve and improve the inter-provincial and inter-regional fishery prevention and coordination mechanism to ensure the safety management of nearby fishing vessels in the vicinity.
Third, implement defense measures. Organize farmers to grab crops such as mature late rice, do wind-proof treatment of fruit trees and greenhouse facilities, and timely clear the field ditches to prevent large-scale internal sputum. Grasp the reinforcement of livestock and poultry houses, thoroughly clean up the drainage system of dredged livestock and poultry farms, and avoid casualties of people and livestock. Quickly mobilize relevant fishing vessels and farmers in the relevant sea areas to return to Hong Kong as soon as possible or to avoid wind and waves, and to strengthen and maintain fishing port facilities and dams as early as possible to ensure the safety of personnel. Guide agricultural enterprises, schools, hospitals and other units to do relevant prevention work.
Fourth, pay close attention to production and self-help. Organize experts to scientifically assess the impact of disasters, strengthen classification guidance, and implement disaster prevention and relief measures according to local conditions. Increase the input of machinery and manpower, remove the stains in time, and promote the recovery of the affected crops. Do a good job in the distribution of seeds, seedlings, fertilizers, pesticides, vaccines and other production materials. In combination with the development of winter agriculture, timely guidance to farmers to do a good job of replanting and replanting. Repair ports, dams, fishing boats, fish ponds and breeding facilities damaged by typhoons as soon as possible to help livestock and fish aquaculture farmers resume production as soon as possible. Strengthen the prevention and control of animal epidemics in the disaster areas, and prevent the outbreak of major animal diseases and zoonotic infectious diseases after the disaster.
