Problems solved by technology

On the one hand, a large amount of cold water is heated to a process temperature of 95°C-98°C, which requires a large amount of steam; on the other hand, the discharged high-temperature sewage is extremely unfavorable to the currently widely used biochemical sewage treatment, and needs to be cooled first, which consumes electricity and energy. Water, site equipment and other resources will generate new costs

Embodiment Construction

[0014] As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the present invention mainly consists of a waste water tank 11, a heat exchange device A, a connecting pipe fitting 1, a waste water inlet 4, a waste water outlet 7, and a cold water inlet 9. The cold water outlet 8 is composed of a waste hot water inlet 4 on the upper part of one end of the waste hot water tank 11, and a waste hot water outlet 7 on the lower part of the other end. In the waste hot water tank 11, there are multiple Each heat exchange device A is provided with a double-layer water baffle 12 connected to the waste water tank 11 between each heat exchange device A, and each heat exchange device A is connected through connecting pipe fittings 1. The upper and lower parts of the device A are respectively provided with the same heat exchange chamber 5, and the upper and lower heat exchange chambers of each heat exchange device are connected through evenly distributed heat exchange tubes 6, and the cold water inlet...

Abstract

This invention discloses a heat exchanger used for warming up cold water in textile printing field, characterized in that in the top and lower of the waste hot-water tank it has a waste hot-water inlet and a waste hot-water outlet, and inside the waste hot-water tank it sets several heat exchanging devices; between each device there is a double manger board connecting with the waste hot-water tank, and each heat exchanging device are connected together through the connecting piece; on the top and lower of the heat exchanging device it has a heat exchanging cavity connected by the evenly distributed heat exchanging pipe; the cold water inlet is connected with the heat exchanging cavity in the lower of the heat exchanging device, while the outlet is connected with the heat exchanging cavity in the top of the heat exchanging device.

Description

technical field [0001] The invention relates to a heat exchanger used in the field of printing and dyeing, which can raise the temperature of cold water. Background technique [0002] At present, groundwater (about 15°C), tap water (about 8°C-20°C), or river, river and lake water (about 0°C-30°C) are widely used as water sources in pre-treatment, descouring, bleaching, and washing processes in printing and dyeing factories. It is heated by steam to 95°C-98°C for desizing and washing, and at the same time, the high-temperature sewage with slurry, dyes and other dirt after a large amount of use is discharged to the sewage treatment station. On the one hand, a large amount of cold water is heated to a process temperature of 95°C-98°C, which requires a large amount of steam; on the other hand, the discharged high-temperature sewage is extremely unfavorable to the currently widely used biochemical sewage treatment, and needs to be cooled first, which consumes electricity and ener...
