Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a condenser forward and backwash cleaning system. Background Art

[0002] In the industrial manufacturing process, cooling water is increasingly used, and it plays a vital role in maintaining the stable operation of production equipment. However, as the cooling water usage cycle increases, dust in the air is easily sucked into the cooling tower system, causing the water quality to gradually deteriorate. This deterioration is manifested in the continuous deposition of minerals, microorganisms and other impurities in the cooling water on the inner wall of the pipe and condenser end, forming a slime layer, which seriously affects the heat exchange effect of the condenser and increases energy consumption.

[0003] To alleviate this problem, users usually need to clean the condenser regularly. Traditional cleaning methods include manual cleaning and chemical cleaning, but these methods have many defects. First, they can only achieve one-way cleaning, and the cleaning effect is limited. Secondly, if reversing cleaning is required, the pipeline must be reconnected, which is not only cumbersome to operate, but also has the risk of overflow of cleaning liquid and polluting the environment. In addition, the outlet pressure and reflux pressure of the cleaning water pump in the traditional cleaning method are inconvenient to adjust, which further affects the cleaning effect and efficiency.

[0004] In view of the many problems existing in traditional cleaning methods, such as incomplete cleaning, time-consuming and labor-intensive, and potential environmental pollution, there is an urgent need for a new type of condenser cleaning device to overcome these defects. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present application aims to provide a pipeline cleaning device, which can easily achieve forward and reverse washing states through valve conversion without disassembling the original pipeline, and can effectively remove dirt inside the condenser to improve the heat exchange efficiency and service life of the condenser.

[0006] To achieve the above objectives, this application is implemented through the following technical solutions:

[0007] The present application provides a condenser forward and backwash cleaning system, comprising a cleaning water tank, a water pump and a forward and backwash reflux device, wherein the cleaning water tank is used to store cleaning liquid, the water pump is connected to the water outlet of the cleaning water tank, and is used to extract the cleaning liquid from the cleaning water tank and reflux it, the forward and backwash reflux device is connected to the water outlet and water inlet of the water pump and the water outlet and water inlet of the condenser, and comprises a cleaning liquid circulation loop and a condenser forward and backwash cleaning loop, and is used to circulate and clean the condenser; wherein:

[0008] The cleaning liquid circulation loop comprises a first pipeline, a regulating valve, and a second pipeline connected in sequence, wherein one end of the first pipeline away from the regulating valve is connected to the water outlet of the water pump, and one end of the second pipeline away from the regulating valve is connected to the water inlet of the clean water tank, a first interface and a second interface are provided on the first pipeline, and a third interface and a fourth interface are provided on the second pipeline;

[0009] The forward and backwash cleaning circuit of the condenser includes a third pipeline, a first three-way valve, a fourth pipeline, a fifth pipeline, a second three-way valve, and a sixth pipeline; the A end of the first three-way valve is connected to the water inlet of the condenser, the B end of the first three-way valve is connected to the first interface of the first pipeline through the third pipeline, and the C end of the first three-way valve is connected to the third interface of the second pipeline through the fourth pipeline; the A end of the second three-way valve is connected to the water outlet of the condenser, the B end of the second three-way valve is connected to the second interface of the first pipeline through the fifth pipeline, and the C end of the second three-way valve is connected to the fourth interface of the second pipeline through the sixth pipeline.

[0010] As a further improvement of the present application, a filter is provided at the water inlet of the first pipeline. Preferably, the filter is a Y-type filter, a T-type filter, or a basket filter. The function of the filter is to filter impurities in the cleaning liquid to prevent the impurities from entering the condenser and affecting the cleaning effect and condenser performance.

[0011] As a further improvement of the present application, the A end of the first three-way valve is connected to the water inlet of the condenser through the seventh pipeline; the A end of the second three-way valve is connected to the water outlet of the condenser through the eighth pipeline. Preferably, the seventh pipeline is a hose; the eighth pipeline is a hose. The design of the hose helps to protect the condenser from damage due to vibration.

[0012] As a further improvement of the present application, the regulating valve is any one of a ball valve, a butterfly valve, and an eccentric rotary valve.

[0013] As a further improvement of the present application, the water pump is a circulating water pump.

[0014] The beneficial effect of the present application is that the present application provides a condenser forward and reverse washing cleaning system, including a forward and reverse washing reflux device, which can efficiently clean the condenser pipeline by adjusting the direction and pressure of the water flow through a valve, without replacing the traditional connection and cleaning water inlet and outlet pipelines, only with one water pump supplying water. This innovative design not only optimizes the limitations of traditional cleaning methods that can only clean in one direction or need to replace the pipeline for backwashing, but also effectively avoids the environmental pollution caused by the leakage of cleaning liquid caused by replacing the pipeline. In addition, the recycling of cleaning liquid also reduces resource waste and pollution to the environment. BRIEF DESCRIPTION OF THE DRAWINGS
