1, the working principle
The unit is mainly composed of mixing tank, circulation pump, return water pressurization pump, temperature control device, control instrumentation and control cabinets and other components. This unit has high heat transfer efficiency, low manufacturing cost, energy saving effect is remarkable, the main feature is a high-temperature water and low-temperature secondary water in the mixing tank of the direct mixing of heat transfer, and make full use of the pressure of the primary water, to minimize the secondary water circulating water pump power. Unit has the following characteristics: 1, heat transfer efficiency up to 100%. Due to the high and low temperature water partially or fully mixed, high and low temperature return water without temperature difference operation, and there is no fouling of the thermal resistance, so the efficiency of the heat exchanger unit is as high as 100%, much higher than the plate and shell and tube heat exchanger unit. 2, performance characteristics (1) high-temperature primary water and part of the secondary water return water into the mixing tank for heat transfer, enhance the temperature of the secondary network into the heating water supply system, the other part of the return water directly back to a high-temperature water system, so that the temperature difference between the high-temperature water heat transfer from 30 ℃ to 70 ℃, in the case of maintaining the low-temperature secondary water flow unchanged, high-temperature primary water flow is reduced to one-half; in the case of a certain amount of heat transfer, the temperature difference of the secondary water increases. In the case of a certain amount of heat transfer, the temperature difference between the secondary water is increased to twice the original, the amount of circulating water is reduced to about one half of the original. (2) Save investment in pipeline network, in the case of the same amount of water in the secondary delivery of high-temperature primary water flow reduced to about 50%, high-temperature water pipe diameter can be reduced by 20%, the cost reduced by about 30%. (3) saving electricity, for example, for 100,000 square meters of heating area, other conventional heat exchanger unit needs to be equipped with equipment 45KW (Q = 45 cubic meters / hour, H = 32m, P = 45KW) of the pump, each heating period of power consumption costs 129,630,000 yuan, if the use of water-water direct mixing of heat exchanger unit for the cost of 83,000 yuan, an annual savings of 49,630,000 yuan. (4) no need for water softening device, can save investment, after normal operation of the system, do not need to start the make-up water pump, due to the use of new technology, a high-temperature water can be directly replenished into the secondary pipeline network, can greatly reduce the system to make up for the pressure of the electricity and water consumed by the water. (5) safe and reliable, the unit has a highly intelligent automation control, can realize the overpressure, over temperature, automatic adjustment of the secondary network system temperature and other functions, and can realize the operation of the course of the monitoring, to provide users with a worry-free operation platform. (6) the whole set of compact structure, covers an area of small, greatly save the investment in civil engineering, at the same time, due to the high efficiency of heat transfer, the system does not need to replenish water, the whole set of power-saving, water-saving effect is remarkable, for the user to create considerable economic benefits. (7) wide range of application conditions, high temperature primary network pressure, temperature adaptability heat transfer rate of 100%, much higher than the plate and shell and tube heat exchanger unit. 1、Working principle
The heat exchanger unit takes the high-efficiency heat-sensitive sensing heat exchanger as the main unit, and highly integrates the circulating pressure stabilizing system and control system of the general-purpose heat exchanger station into a whole, and makes full use of the contemporary advanced technologies such as flow rate frequency control, heat automatic monitoring control and telecommunication communication control, so as to make the unit realize the automation and intelligence to the greatest extent possible. The whole unit is well-coordinated and well-combined, tailor-made, and the whole unit is shipped from the factory, which is quick and convenient to install, and the installation cost is extremely low. 2, thermal sensing heat transfer unit features
(1) rapid heat transfer, heat transfer efficiency, heat transfer efficiency of up to 100%. (2) full recovery of condensate, recycling, the entire system water self-cleaning anti-scaling, heat exchangers, radiators and heat transfer system can maintain long-term stable and efficient heat exchange performance, minimize the system scaling phenomenon, will not be difficult to overcome the scaling drawbacks and reduce the efficiency of the system heat transfer. (3) The heat exchanger is made of stainless steel, with scientific structural design, excellent craftsmanship and long service life of more than 20 years. (4) The key components are processed by advanced technology and orders from Germany, so that the host is not affected by steam pressure and system pressure, effectively eliminating noise, vapor strike phenomenon, and the whole machine runs smoothly. (5) Condensate is completely absorbed and utilized, and there is no special reason for the system to set up a water replenishment device, which greatly saves the system water and operating costs. (6) The whole unit has compact structure and small footprint, which greatly saves the investment in civil construction. Meanwhile, due to the high efficiency of heat exchange, the system does not need to make up water during operation, so the whole unit saves steam, electricity and water in one, which creates considerable energy-saving benefits for the users. (7) The unit is equipped with highly intelligent automatic control function, which can realize over-pressure and over-temperature protection, automatic steam cut-off in power failure and automatic compensation of outdoor temperature, and can realize remote monitoring, providing users with a worry-free operation platform. (8) Wide range of applications, can be widely used in thermoelectricity, factories and mines, food and medical care, machinery and light industry, civil construction and other fields of heating, hot water bathing and other purposes. (9) Wide range of application conditions, can be used for larger pressure, temperature range of heat exchange.
