Description

Technical Field

[0001] This utility model relates to the field of evaporators, and in particular to a novel membrane stack high-efficiency evaporator. Background Technology

[0002] In existing technology, evaporation is a physical process of transforming a liquid into a gaseous state. Generally speaking, an evaporator is an object that transforms a liquid substance into a gaseous state. There are numerous evaporators in industry, among which the evaporator used in refrigeration systems is one type. The evaporator is a crucial component of the four main parts of a refrigeration system. Low-temperature condensed liquid passes through the evaporator, exchanging heat with the outside air, vaporizing and absorbing heat to achieve a cooling effect. An evaporator mainly consists of two parts: a heating chamber and an evaporation chamber. The heating chamber provides the heat required for evaporation to the liquid, causing it to boil and vaporize; the evaporation chamber completely separates the gas and liquid phases.

[0003] Existing evaporators are inefficient and energy-intensive, and when heating liquids, the bottom is hot and the top is cold most of the time, resulting in low heating efficiency. At the same time, the evaporation efficiency also slows down with the heating efficiency. Utility Model Content

[0004] This application provides a novel membrane stack high-efficiency evaporator, which solves the problems of high energy consumption and low heating efficiency in existing evaporators, where the bottom is hot and the top is cold most of the time when heating the liquid, and the evaporation efficiency also slows down with the heating efficiency.

[0005] The technical solutions adopted in the embodiments of this application are as follows.

[0006] A novel membrane stack high-efficiency evaporator includes a heating tank, a circulation device for circulating liquid within the heating tank, a water supply device for discharging liquid into the heating tank, a fan for condensing water vapor, and a membrane stack to increase evaporation capacity. A pushing member is located at the top of the heating tank; the active end of the pushing member extends into the heating tank, and the membrane stack moves up and down via the pushing member. One end of the circulation device is connected to the bottom of the heating tank, and the other end is connected to the top of the heating tank. One end of the water supply device is connected to a water source, and the other end is connected to the top of the heating tank. The fan is connected to the top of the heating tank.

[0007] As a further improvement to the above technical solution: the circulation device includes a circulation pump, a first pipe disposed at the inlet of the circulation pump, a second pipe disposed at the outlet of the circulation pump, a third pipe connected to the second pipe, and a first thermometer for detecting the temperature of the circulating liquid; the first pipe is connected to the bottom of the heating tank; the second pipe is connected to the top of the heating tank; the third pipe is arranged perpendicular to the second pipe; a first valve is disposed on the second pipe; a second valve is disposed on the third pipe; when the first valve is open and the second valve is closed, the liquid circulates within the heating tank; when the first valve is closed and the second valve is open, the liquid within the heating tank is discharged.

[0008] As a further improvement to the above technical solution: a vacuum pressure gauge and a second thermometer are provided on the top of the heating tank.

[0009] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0010] 1. By employing a membrane stack design to increase evaporation capacity, the evaporation efficiency is effectively improved, solving the problem of low evaporator efficiency in existing technologies. The vertical movement of the membrane stack makes the liquid circulation within the heating tank more uniform, avoiding the uneven heating phenomenon in traditional evaporators and improving thermal energy utilization efficiency. Secondly, the circulation device design of this invention, including a circulation pump and piping, enables effective circulation of the liquid within the heating tank, not only improving heating efficiency but also contributing to a uniform liquid temperature distribution, thereby further enhancing evaporation efficiency. Furthermore, by setting a first valve and a second valve, the circulation state of the liquid within the heating tank can be adjusted or the liquid can be discharged from the heating tank as needed, enhancing the system's flexibility and controllability.

Simultaneously, because thermal energy utilization is more efficient, product quality is also improved. By improving thermal energy utilization efficiency, this invention reduces energy consumption and has positive significance for energy conservation and emission reduction; it improves heating uniformity: traditional evaporators have the phenomenon of hot bottom and cold top, while this invention makes heating more uniform by moving the membrane stack up and down; it enhances system controllability: through the valve settings of the circulation device, the operator can adjust the liquid circulation state according to actual needs, which enhances the controllability and flexibility of the system, thereby achieving high heating efficiency.
