Description

Technical Field

[0002] The evaporator is a device used for gas-liquid separation. The gas and liquid are recovered and processed separately through the separation of gas and liquid. The condenser is an important link in the cyclic evaporation process, which is used to reduce the temperature of the gas-liquid mixture. The evaporator and condenser occupy an important position in chemical, petroleum, power, food and many other industrial productions, and are widely used in chemical production. When the evaporator is working, the low-pressure working fluid steam coming out of the evaporator is sucked in by the compressor, and the pressure is increased and then sent to the condenser. In the condenser, it is condensed into a liquid with a higher pressure. After throttling by the throttle valve, it becomes a liquid with a lower pressure and is sent to the evaporator. It absorbs heat and evaporates in the evaporator to become steam with a lower pressure, thereby completing the refrigeration cycle. The integrated multi-effect evaporator structure disclosed in the publication number CN217246803U is provided with a condensation box, a storage box, an exhaust pipe and a transparent scale plate. A valve and a storage box are provided at one end of the condensation box, and the exhaust is discharged through the exhaust pipe.

[0020] Working principle: When using the single-effect evaporator structure, firstly, the liquid is controlled by the liquid inlet valve 25 to enter the evaporation chamber 22 from the cylinder 5 through the liquid inlet 15. The reinforcement ring 14 is used to strengthen the structure of the liquid inlet 15. The liquid falls into the cone bottom 16 under the action of gravity, and the gas-liquid mixture enters the condensation heat exchange chamber 20. The heat exchange treatment is carried out through the condensed water in the tubes 21 to achieve condensation treatment, so that the gas and liquid are separated. After the gas passes through the condensation heat exchange chamber 20, it reaches the cone top 3. The evaporator body 1 performs gas pressure detection processing through the pressure gauges installed at the first pressure gauge port 11 and the second pressure gauge port 17, and the internal working conditions are checked through the sight glass 19 at the sight glass port 18.
