Problems solved by technology

[0004] 1. The air cooling tower pollutes the environment, the surrounding air is humid, and the water mist is serious;
[0005] 2. It causes waste of heat energy, and a large amount of heat is discharged into the air, causing heat waste and heat pollution;
[0006] 3. Energy waste is generated, the water entering and exiting the air cooling tower needs the hot water pump to consume power, and the air cooling tower itself consumes power

Abstract

The invention discloses a system for evaporating corn soaking water in production of corn starch. The system comprises a four-effect evaporator, wherein a fourth effect body of the four-effect evaporator is connected with a high-level condensation tank through a steam guide pipeline; a water tank is arranged below the high-level condensation tank, and communicated with a water pump; a tube heat exchanger is tightly communicated between the high-level condensation tank and the water pump, and comprises a water inlet, a water outlet, a refrigerant inlet and a refrigerant outlet; the water inlet is communicated with the water outlet; the refrigerant inlet is communicated with the refrigerant outlet; the water inlet is communicated with the water pump; the water outlet is communicated with the high-level condensation tank; the refrigerant inlet is tightly communicated with an intake pipe; an intake valve is arranged on the intake pipe; the refrigerant outlet is tightly communicated with a discharge pipe; a discharge valve is arranged on the discharge pipe; a middle pipe is tightly communicated between the intake pipe and the discharge pipe; and a middle valve is arranged on the middle pipe. An air cooling tower is replaced by the tube heat exchanger, and the specification and model of the tube heat exchanger can be selected according to the evaporation capacity, the refrigerant flow rate and the temperature difference.

Description

Technical field [0001] The invention relates to an evaporation system, in particular to an evaporation system for soaking corn water in corn starch production. Background technique [0002] At present, most corn starch production enterprises use four-effect evaporators to concentrate the soaked corn water and process it into corn syrup with a dry matter content of about 40%, such as Figure 5 As shown, the secondary steam produced by the fourth effect body evaporator enters the high-level condensing tank through the steam guide pipe, and the cold water pump sends the cold water to the high-level condensing tank. After the cold water absorbs heat, the temperature rises and becomes hot water, which is then discharged to the water tank. The hot water is sent to the air cooling tower through the hot water pump, and becomes cold water after cooling. The cold water pump can send it to the high-level condensing tank again, realizing the recycling of water. [0003] However, this technique ...
