Embodiment Construction

[0009] figure 1 As shown in a centrifugal evaporator, the pipes 1 of the evaporator are arranged in a cylinder as shown in Figure 2, and cylindrical wind impellers 2 and 3 are respectively arranged inside and outside the cylinder of the evaporator pipe. Two cylindrical wind impellers are connected concentrically and coaxially on the 4 shafts of the motor. There are windshields 5 at the outer ends of the two cylindrical wind impellers. There are cooling fins on the pipeline of the evaporator (Fig. 2 is the state of removing the cooling fins).

Abstract

The present invention relates to a centrifugal evaporator, and its pipe arrangement is formed into the form of cylinder whose interior and exterior are respectively equipped with cylindrical air blade wheel, said two cylindrical air blade wheels are cocentrically and coaxially connected on the motor shaft, and the outside end of every cylindrical air blade wheel is equipped with air deflector. Said two cylindrical air blade wheels can synchronously rotated, so that the evaporator pipe is in the low pressure zone, the vapour does not pass through the evaporator so as to reduce frost formation of the evaporator, and can save energy.

Description

technical field [0001] The invention belongs to refrigeration evaporators, in particular to a centrifugal evaporator. Background technique [0002] During the operation of the current refrigeration evaporator, it is easy to frost. After frosting, the heat exchange efficiency of the evaporator is poor, which wastes energy. Generally, it is necessary to increase defrosting equipment, corresponding facilities, and energy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a centrifugal evaporator without adding defrosting equipment to achieve no frosting. [0004] The technical solution of the present invention is: a centrifugal evaporator, which is characterized in that: the pipes of the evaporator are arranged in a cylinder, and cylindrical wind impellers are respectively arranged inside and outside the cylinder of the pipe of the evaporator. Two cylindrical wind impellers are connected concentrically and coaxially ...
