Compared with the prior art, the above plate evaporator has the following beneficial effects: a plurality of metal evaporation plates are arranged in the concentration and evaporation chamber inside the plate evaporator, and the plate body has a certain inclination angle.
The evaporator is a very important part of the four refrigeration components. The low-temperature condensate and the outside air exchange heat through the evaporator, and the gasification and heat absorption achieve the refrigeration effect. The evaporator is mainly composed of an evaporation chamber and a heating chamber. The heating chamber provides the heat required for evaporation of the liquid and promotes the boiling and evaporation of the liquid; The evaporation chamber completely separates the gas phase and the liquid phase, including the plate evaporator, which is an evaporation device that uses metal plates instead of round tubes as heat transfer elements. The scale on the evaporator plate is easy to remove and cheap, but the rigidity and strength of the plate are far lower than that of the round tube. In order to improve the rigidity and strength of the metal plate, various heating elements with different structures, such as spiral rice heating element and gas-filled plate heating element, have emerged. However, the evaporation area of the existing plate evaporator is limited. Due to the influence of the plate surface, the evaporation energy consumption of the evaporator will increase when the flow increases; Therefore, it can not meet the existing demand, so we propose a plate evaporator.
Our technicians provide a plate evaporator to solve the problem that the evaporation area of the plate evaporator is limited due to the influence of the plate surface, so that when the flow rate increases, the evaporation energy consumption of the evaporator will increase. In order to achieve the above purpose, the plate evaporator adopts the following technical scheme: a plate evaporator, including the evaporator body. The two ends of the evaporator body are equipped with end face sealing plates. The end face sealing plate is equipped with an evaporator shell. The evaporator shell is surrounded by an external fixed angle rod. The heat source inlet is set above one side of the evaporator body, and the heat source outlet is set below the other side of the evaporator body, The evaporator main body is equipped with a concentration and evaporation chamber. The concentration and evaporation chamber is equipped with multiple metal evaporation plates. One side of the metal evaporation plate is equipped with a connecting pipe. The outer surface of the metal evaporation plate is equipped with a polytetrafluoroethylene coating. The inner part of the metal evaporation plate is equipped with a heat source flow chamber. The end sealing plate is connected with the evaporator shell and the outer fixed angle rod through bolts. The heat source inlet and heat source outlet are connected with the metal evaporation plate through pipes, and the metal evaporation plate is combined with the concentration evaporation chamber. The first interface and the second interface are connected with the transmission pipeline through flanges. The metal evaporation plates can be combined and connected, and the metal evaporation plates are horizontally staggered. The condensate outlet, raw material inlet and concentrate outlet are connected with the end sealing plate through flanges, and the metal evaporation plate is connected with the polytetrafluoroethylene coating through adhesive.
Compared with the prior art, the above plate evaporator has the following beneficial effects: a plurality of metal evaporation plates are arranged in the concentration and evaporation chamber inside the plate evaporator, and the plate body has a certain inclination angle. The metal evaporation plates are horizontally arranged inside, and each plate body is alternately distributed downward in turn. The first interface and the second interface are respectively arranged on both sides of the metal evaporation plate. Since the plate evaporator itself is horizontally placed, when the raw materials enter, The metal evaporation plate has a certain inclination. The principle of the longest inclined edge can be obtained by using the Pythagorean theorem, which can increase the contact area between the raw material and the additional plate, thus improving the evaporation efficiency of the evaporator.
