Embodiment Construction

[0019] Such as figure 1 As shown, it is a double-effect evaporator with automatic control function of the present invention, including a raw material tank 1, a preheating device, a first-effect evaporator unit, and a second-effect evaporator unit connected sequentially through pipelines;

[0020] The preheating device includes a plate heat exchanger unit connected to the raw material tank 1 through the feed pump 2, and the raw material enters the plate heat exchanger unit from the raw material tank 1 through the feed pump 2 for preheating;

[0021] The one-effect evaporating unit includes a one-effect forced circulation heat exchanger 3, and the preheated raw material enters the one-effect forced circulation heat exchanger 3, and the one-effect forced circulation heat exchanger 3 transfers the raw material reaching the evaporation temperature to Delivered to the first-effect separator 4 connected thereto;

[0022] The two-effect evaporation unit includes a two-effect forced c...

Abstract

The invention discloses a double-effect evaporator with an automatic control function and relates to the technical field of chemical equipment. The double-effect evaporator comprises a raw material tank, a preheating device, a single-effect evaporating unit and a double-effect evaporating unit connected in sequence through a pipeline. The preheating device comprises a plate type heat exchanger unit connected to the raw material tank through a feeding pump; a raw material enters the plate type heat exchanger unit through the feeding pump from the raw material tank to be preheated; a material converting pipeline is also arranged between a single-effect separator and a double-effect separator; an electric proportioning valve is arranged on the material converting pipeline, the double-effect separator is connected to a liquidometer, and the opening of the electric proportioning valve is controlled by the liquidometer, so that the liquid level heights of the double-effect separator and thesingle-effect separator are kept in a preset range. The double-effect evaporator with the automatic control function reduces the manpower input and lowers the labor cost through an automatic control system and achieves automatic double-effect evaporation.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a double-effect evaporator with an automatic control function. Background technique [0002] The disposal of high-salt wastewater is a worldwide problem. my country produces more than 300 million cubic meters of such wastewater every year, and the by-products of high-salt hazardous waste exceeds 10 million tons. pressure. The evaporation concentration method is widely used in the treatment of high-salt wastewater, and can be produced on a large scale. At present, the equipment for double-effect evaporation still requires a lot of labor. Labor cost, to realize the automation of two-effect evaporation. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a double-effect evaporator with automatic control function. [0004] The present invention adopts following technical scheme: [0005] A double-effect eva...
