Embodiment Construction
[0008] In order to gain an in-depth understanding of a solvent recovery system water-saving device, combined with figure 1 described as follows:
[0009] A water-saving device for a solvent recovery system, comprising a condensing device 4, a pipeline 2 with a water-cooled pipe 4 wrapped inside, one end of the pipeline 2 connected to the dehydration tower 1, and the other end of the pipeline 2 connected to the air-cooled pipe in the air cooler 5 6. The air-cooled pipe 6 is S-shaped and distributed inside the air cooler 5 , one end of the air-cooled pipe 6 is connected to the delivery pipe 2 , and the other end is the material inlet 7 . The water-saving method of the solvent recovery system adds an air cooler. Before passing through the condensing device, air pre-cooling is used to reduce the temperature of the material, and the initial temperature is lowered to 60°C to reduce the heat that needs to be taken away by the circulating water.

The invention relates to a solvent recovery system water saving apparatus, and belongs to the field of chemical industry equipment. The apparatus comprises a condensing device, wherein the internal is provided with a conveying pipeline wound with a water cooling pipe, one end of the conveying pipeline is connected with a dehydration tower, the other end of the conveying pipeline is connected with an air cooling pipe inside an air cooler, the air cooling pipe is distributed inside the air cooler in an S type manner, one end of the air cooling pipe is connected with the conveying pipeline, and the other end is a material inlet. According to the solvent recovery system water saving method, the air cooler is added, and air pre-cooling is adopted before the material passes through the condensing device, such that the material temperature is reduced, the temperature is initially reduced to 60 DEG C, and heat taken away by circulating water is reduced.
Description
technical field [0001] The invention relates to a water-saving device for a solvent recovery system, which belongs to the field of chemical equipment. Background technique [0002] At present, the solvent dehydration tower used for acetic acid and isobutyl acetate is cooled by a water cooling system, which consumes a lot of water and requires a high water flow rate, which results in a large work consumption of the water pump and consumes a lot of energy in actual use. Contents of the invention [0003] In view of the defects in the prior art, the object of the present invention is to provide a water-saving device for a solvent recovery system, which can reduce the loss of circulating water and reduce the working frequency of the water pump. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a solvent recovery system water-saving device, including a condensing device, a pipeline with a water-cooled pipe winding inside,...
