Evaporation concentration system

Abstract

The invention provides an evaporation concentration system. The evaporation concentration system is characterized in that a discharge outlet of a heater is connected with a feed inlet of an evaporation separator, and a steam-water separation system is connected with the heater; a steam-water separator is connected with a liquid level tank, a liquid level sensor is arranged inside the liquid leveltank, a regulation type electric valve is connected with a drain opening of the steam-water separator, and a liquid level monitoring system is connected with the liquid level sensor and is connected with the regulation type electric valve; the opening degree of the regulation type electric valve can be controlled by the liquid level monitoring system according to the liquid level sensor. Accordingto the scheme, the evaporation concentration system has the advantages that the liquid level tank is communicated with the steam-water separator, the internal liquid level of the liquid level tank can be measured by the liquid level sensor, and accordingly the height of the liquid level of the steam-water separator can be monitored; the opening degree of the regulation type electric valve can beregulated by the liquid level monitoring system according to data of the liquid level sensor, so that the drain speed of the steam-water separator can be controlled, the liquid level of the steam-water separator can be guaranteed against being excessively high or excessively low, and liquid impact and gas movement phenomena can be prevented.

Description

technical field [0001] The invention relates to the field of evaporation concentration, in particular to an evaporation concentration system. Background technique [0002] In the food industry and chemical industry, many products need to be concentrated. As a process in the production process, the water in the product is mainly converted into water vapor and evaporated from the product solution to increase the product concentration. For example, dairy products in food, urea in chemical industry, etc. need to be evaporated and concentrated for the next step. [0003] In the concentration, the method of evaporation and concentration is often used for concentration, and the use of hot steam as the heat source is the most widely used. In the process of heating with hot steam, a large amount of water needs to be discharged. Generally, devices such as steam traps are used to discharge the condensed water of the heater. Among them, the condensed water output of the heater is affe...

AI Technical Summary

Problems solved by technology

Among them, the condensed water output of the heater is affected by many aspects such as the amount of water in the steam, steam saturation, steam temperature, and vacuum degree of the evaporation system. Therefore, the drainage rate of steam traps and other equipment needs to be adjusted according to the actual situation. Excessive condensed water on the steam trap will cause liquid shock in the pipeline, or discharge too fast to cause air leakage. Both liquid impact and air leakage will cause vibration of pipelines and valves, resulting in damage to pipelines and valves, water leakage, and air leakage.

[0004] At the same time, in the process of evaporation and concentration, the water from the product and the condensed water from the heater cannot be fully utilized, resulting in waste of water resources
