First, what is the heat pump: Simply put, all those who can send low-temperature heat at high temperatures become available to life, production needs of the device, collectively referred to as heat pump. We all know that water will automatically flow from high to low; the heat can also be automatically transmitted from high temperatures to low temperatures. However, usually to lower the water sent to a height, usually with a mechanical pump to do such a job, people put the water pump mechanical pump called. So, to take the heat at low temperatures and sent out to high temperatures, making it a useful heat, the production are generally used in compressors, so people put this heat transfer compressor called the heat pump. With the help of heat pumps, we can make full use of low-temperature heat sources to obtain high temperatures to meet various needs such as evaporation unit operation, drying, heating, concentration of fruit juice and medicines, and the like. To achieve heat pump heating, there must be a matching equipment, such as evaporator, compressor, condenser, expansion valve together with the working medium to form a complete heat pump cycle. The above is only a compression heat pump as an example to illustrate the simple concept of heat pump. In addition there are other types of heat pumps, but the principle is basically the same. Second, the heat pump system for evaporation and concentration: in the nuclear industry system, a large number of low-radioactive waste water, which is characterized by large wastewater volume, low salt content, the most suitable heat pump evaporation method. Conventional evaporation of this type of wastewater is shown in Figure 1. During the evaporation process, the boiler room continuously provides the steam (primary steam) to the evaporator to evaporate the radioactive waste water entering the evaporator, which inevitably consumes a large amount of fuel. However, the steam evaporated by the evaporator (secondary steam) has to be drained off after condensing it into water with a large amount of cooling water. A lot of cooling water to the secondary steam latent heat to the cooling tower to the atmosphere, a lot of heat wasted. Not only waste heat, but also consume a lot of cooling water. If the use of heat pump steam treatment of radioactive waste, as shown in Figure 2. In the process of heat pump evaporation, the secondary steam is recovered by the compressor, and then it is returned to the heating chamber of the evaporator instead of the primary steam of the boiler room after being raised in temperature and pressure. That is, with secondary steam booster heating evaporation and then go to the waste water, as the secondary steam to the heat transfer to the waste water to evaporate, so the secondary evaporation itself is evaporated while condensing water, that is, the final purified water. The wastewater is continuously evaporated in the evaporator to be concentrated, and the concentrated radioactive waste liquid is collected from the bottom of the evaporator and treated separately. If the heat pump evaporation system be cleverly designed, you can save the boiler room, cooling water system in the conventional evaporation method, which is economically significant. So heat pump is an energy efficient device. Third, the use of heat pump device Where to use steam for purification, condensation, drying, separation, purification and other operating units in the heat pump device can play its advantages, chemical, food, light industry, medicine, textile, petroleum, environmental protection and other industries For example, for corn starch concentrate concentrates, heat pump can be 4% solids immersion liquid concentrated to 46% or more, the heat pump evaporation method compared with ordinary single-effect evaporator can save about 80%, concentration ratio Up to 12 times. Heat pump low energy consumption, purification effect, enrichment multiple, compact device structure, easy operation, safe and reliable, easy to automate. Heat pump device will be fully utilized in economic construction.
Our burner valves can be sold in combination according to customer's requirements and size requirements.Conventional stainless iron burners and stainless steel burners can be matched with copper and zinc valves of the corresponding size.So we also call them copper valve and Zinc Valve burners.
Our current main market is Africa and the Middle East, and we have become the largest supplier of cooking utensils in Nigeria in the past two years.In the future, we will develop new products to improve the quality and service, and enter the European and American markets.
