Problems solved by technology
The evaporative condenser uses spray water as the cooling medium. The water forms a water film outside the heat exchanger and exchanges heat with the process fluid in the heat exchanger. After absorbing heat, the temperature rises and forms water vapor under the action of high-speed airflow. If The initial temperature of the process fluid entering the heat exchanger is higher than 70°C, which is the easy scaling temperature of water. The water flowing through the surface of the heat exchanger is easy to scale on the surface of the heat exchanger. Will affect the heat transfer efficiency of the heat exchanger

Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:
[0023] like figure 1 The double-cooled condenser shown includes a condenser shell 1, a heat exchanger 2 is arranged in the middle part of the condenser shell, and the heat exchanger 2 includes a number of vertically parallel heat exchange plates 20, There is a cooling gap 21 between the hot plates, such as image 3 As shown, the heat exchange plate 20 is provided with a number of parallel fluid channels 22. The heat exchange plate 20 is made by connecting two corrugated heat-conducting plates 23, and the convex surfaces of the two corrugated The fluid channel 22 is formed by the concave surface snap-fitting connection. The cooling gap 21 is provided with a heat exchange packing plate 27. The heat exchange packing plate is formed by superimposing two trapezoidal corrugated plates 28. The top surface of the trapezoidal corrugated plate is provid...

The invention relates to the technical field of condensers, and discloses a double-cooling condenser, which includes a condenser shell, a heat exchanger is arranged in the middle of the condenser shell, and a liquid inlet pipe is arranged on the side of the upper end of the heat exchanger. The side of the lower end of the heater is provided with a liquid outlet pipe, the upper end of the heat exchanger is provided with a water distribution pipe, the lower side of the water distribution pipe is evenly provided with a number of nozzles, and the condenser shell is located at the upper end of the water distribution pipe. There is an exhaust port on the top, an air intake grille on the side of the lower end of the condenser shell, a sump at the bottom of the condenser shell, a return pipe on the side of the condenser shell, the lower end of the return pipe is connected to the sump, and the return pipe The upper end is connected with the water distribution pipe, the return pipe is provided with a water pump, and the condenser shell is provided with a cooling coil between the exhaust fan and the exhaust port, and the outlet of the cooling coil is connected with the liquid inlet pipe. The invention has the beneficial effects of slowing down the generation of scale inside and outside the heat exchanger and prolonging the maintenance cycle of the heat exchanger.
Description
technical field [0001] The invention relates to the technical field of condensers, in particular to a double cooling type condenser. Background technique [0002] In modern society, the application of refrigeration technology has involved all sectors of the national economy and people's daily life. However, my country's water resources are scarce, especially under the situation of increasingly tense power resources in recent years, there are higher requirements for the energy saving of refrigeration systems. According to the different cooling medium and cooling method, commonly used condensers can be generally divided into water-cooled, air-cooled and evaporative. The evaporative condenser uses spray water as the cooling medium. The water forms a water film outside the heat exchanger and exchanges heat with the process fluid in the heat exchanger. After absorbing heat, the temperature rises and water vapor is formed under the action of high-speed airflow. The initial tempe...
