[0033] Evaporation equipment is widely used in food processing, chemical industry, pharmaceutical industry and environmental engineering and other fields. In this embodiment, the evaporation device is an MVR (Mechanical Vapor Recompression, mechanical vapor recompression technology) evaporator. The principle of the MVR evaporator is to use the high-energy-efficiency steam compressor to compress the secondary steam generated by evaporation, to increase the pressure and temperature of the secondary steam, and the secondary steam with increased heat energy is injected into the evaporation tank to heat the liquid to be evaporated, and the heated to-be The evaporating liquid continues to evaporate to generate secondary steam, so as to achieve a continuous evaporation state.

[0034] Since the MVR evaporator recycles the existing heat energy of the secondary steam, it does not need external fresh steam, which greatly saves the energy consumption of the evaporation system. From a th...

[0067] see figure 2 , an evaporation control method provided in an embodiment of the present application, the evaporation control method can be executed by an evaporation control device of an evaporation control device, and the evaporation control method includes: step S110, and step S120.

[0068] Step S110: Collect the first liquid level value in the evaporation tank of the evaporation device at the first moment.

[0069] Step S120: Determine whether the first liquid level value is within the first preset liquid level range, and if so, control the first regulating valve on the evaporation tank to open, so that the first regulating valve will The steam generated by evaporation is output to the first output pump.

[0070] Additionally, after step S120, the evaporation control method may further include:

[0071] A second liquid level value in the storage tank of the evaporation device at a second moment is obtained. Judging whether the second liquid level value is within t...

Abstract

Embodiments of the present application provide an evaporation control device and method, which relate to the technical field of evaporation devices. The evaporation control device includes: a data acquisition device for collecting the first liquid level value in the evaporation tank of the evaporation equipment at the first moment; an evaporation control device connected with the data acquisition device for determining that the first liquid level value is located in the evaporation tank When the liquid level in the tank is within the first preset liquid level range, the first regulating valve on the evaporation tank is controlled to open, so that the first regulating valve outputs the steam generated by evaporation in the evaporation tank to the output pump. The evaporation control device controls the evaporation process of the evaporation device, which can improve the control efficiency.

Description

technical field [0001] The present application relates to the technical field of evaporation devices, in particular, to an evaporation control device and method. Background technique [0002] MVR evaporating tank is a new type of high-efficiency and energy-saving evaporation equipment mainly used in the pharmaceutical industry. This equipment uses low-temperature and low-pressure steaming technology and clean energy as energy to generate steam and separate water from the medium. It is currently the most advanced evaporation technology in the world. , is an upgraded product that replaces the traditional evaporation tank. At present, manual control is used for the control of the MVR evaporation tank, which can only carry out simple process control. Manual control not only wastes manpower and material resources, but also the control efficiency is not high. Contents of the invention [0003] The purpose of this application is to provide an evaporation control device and meth...
