Description
Technical Field
The invention belongs to the technical field of industrial refrigeration and heat exchange, and particularly relates to a vertical evaporator structure for a water chilling unit.
Background
The heat exchanger is a common device in chemical industry, petroleum industry, power industry, food industry and other industrial departments, and plays an important role in production. The heat exchanger can be used as a heater, a cooler, a condenser, an evaporator, a reboiler and the like in chemical production, and is more widely applied.
The heat exchanger can be divided into a horizontal heat exchanger and a vertical heat exchanger in form, and the differences are mainly as follows:
horizontal heat exchanger: the device is stable and safe, and can bear higher working pressure and temperature; the floor space is large, the requirement on the clear height of the installation space is not high, the maintenance and the cleaning are convenient, and a platform is not needed generally; the cold fluid and the hot fluid can flow in a countercurrent way and a concurrent way; the heat transfer coefficient is medium, the heating retention time is short, and the heat exchange effect is medium.
A vertical heat exchanger: the device is stable and safe, needs to be vertically paved, and generally adopts a tower-shaped structure; the occupied area is small, the requirement on the net height of the installation space is high, the structure is compact, and the pipe arrangement is easy; the cold fluid and the hot fluid are generally in countercurrent; the heat transfer coefficient is larger, the heating detention time is short, and the heat exchange effect is better.
The evaporator is a device for evaporating the liquid refrigerant into gas, and the liquid refrigerant can be boiled violently in the heat exchange process; a certain space height is usually reserved between liquid refrigerant and gaseous refrigerant to ensure that the evaporator sucks air without liquid; for a horizontal shell-and-tube evaporator, in order to ensure such a space height, tubes are not distributed on the upper half part of the section of a tube plate (the tube distribution rate is not high, about 50 percent), so that the defects of large volume and high material cost of a heat exchanger are caused; the vertical evaporator structure is adopted, so that the floor area is small, the tube plate arrangement rate can be greatly improved (improved to 80-95%), the volume of the heat exchanger is reduced, and the material cost is reduced; however, the existing vertical evaporator structure is rarely used due to the following technical disadvantages;
1) the shell-side medium of the flooded evaporator is a refrigerant, the air suction port 3 and the liquid refrigerant inlet 4 are both horizontally arranged, in order to avoid liquid entrainment in the air suction of the compressor, the refrigerant liquid level 2 needs to be lowered to a position below the air suction port 3, so that part of the heat exchange tubes 1 are exposed in the gaseous refrigerant, the heat exchange tubes 1 cannot be used for heat exchange, and the heat exchange efficiency of the evaporator is low, as shown in fig. 1.
2) The liquid level of the refrigerant of the evaporator is mainly influenced by the position of the air suction port and the pipe arrangement; the denser the heat exchange tubes 1 are, the more the gas-liquid mixture is accumulated due to evaporation boiling, and the liquid level is increased; the closer to the inlet port 3, the higher the liquid level due to the influence of the suction pressure. The conventional vertical heat exchanger has the suction port 3 provided at one side of the casing such that the liquid level is higher the closer to the suction port, the higher the risk of liquid entrainment of suction, as shown in fig. 1.
