Description

A device for recovering condensation and cooling water in the cloth printing and dyeing industry

technical field

The utility model relates to a condensation and cooling water recycling device in the cloth printing and dyeing industry, which belongs to the field of energy saving and consumption reduction.

Background technique

Behind the rapid development of my country's printing and dyeing industry is the status quo of high energy consumption, high water consumption and high pollution. During the production process of the existing dyeing process, all the dyeing water is drained to the sewage treatment plant. This causes the waste of the water resources of the enterprise itself, and at the same time the dyeing water also takes away a large amount of heat when it is drained, causing a large amount of waste of the energy of the enterprise. At the same time, the treatment capacity of the sewage treatment plants of downstream enterprises has been greatly increased, which has increased the treatment cost. Today, when the country is making great efforts to promote environmental protection, energy conservation and emission reduction, it is imperative for the printing and dyeing industry to do a good job in clean production, energy conservation and emission reduction, and the reuse rate of water resources.

detailed description

As shown in the attached figure, a condensing and cooling water recovery device for the cloth printing and dyeing industry includes, from left to right, a heat exchanger 1, a recovery pipeline 2, a hot water recovery pool 3, an elevated water tower 4, and a reuse pipeline 5 and reuse part 6; the input end of the recovery pipeline 2 is provided with a number of collection ports 21, the collection ports 21 are arranged below the drain port of the heat exchanger 1, and the collection ports 21 adopt the form of an open horn, The recovery pipeline 2 is connected to the collective water outlet end of the collection port 21, and a gate valve 22 is provided between the recovery pipeline 2 and the collection port 21 near the water outlet of the collection port 21, and the recovery A water pump 31 is provided between the hot water sump 3 and the high-level water tower 4, an intelligent water pump pressure controller 32 is provided between the water pump 31 and the recovered hot water sump 3, and the recycling pipeline A new water inlet pipe 61 is provided between 5 and the reuse part 6 .

Further, the drain port of the heat exchanger 1 is installed vertically with the collecting port 21, and the installation distance is set at 5cm-10cm.

Further, the hot water recovery pool 3 is closed and arranged below the ground.

The implementation process of the utility model is as follows: after indirect heat exchange, the condensed water and cooling water are discharged to the collection port through the drain port of the heat exchanger, and then flow into the recovery hot water collection pool through the recovery pipeline. When the water pressure reaches a certain value (the water temperature is basically stable), the intelligent water pump pressure controller will send a start signal to the water pump, and the water pump will start pumping water into the high-level water tower. The pipeline is used for the reuse part. If the reuse water is not enough, water can be added through the new water inlet pipe. Using a high-level water tower is convenient for water consumption control and water source stability. In addition, when the heat exchanger leaks, the staff can close the gate valve , prevent polluted water from flowing into the next process, and ensure the quality of recycled water.

The condensing and cooling water recovery device of the cloth printing and dyeing industry of the utility model greatly improves the water reutilization rate, reduces the consumption of fresh water, reduces the consumption of steam, and shortens the The production time is reduced, the production efficiency is improved, and the purpose of clean and efficient production, energy saving and consumption reduction is realized.

The above-mentioned embodiments are only descriptions of preferred implementations of the present utility model, and are not intended to limit the concept and scope of the present utility model.
