Description

Technical Field

[0001] The invention belongs to the technical field of municipal engineering pipeline flushing, and specifically relates to a tap water pipeline circulation flushing device, system and method. Background Art

[0002] Pipeline cleaning and disinfection is an essential cleaning project in daily life and production. The existing pipeline cleaning and disinfection are mainly divided into three types: 1. High-pressure flushing method: High-pressure flushing method is a commonly used method for cleaning pipelines. By using a high-pressure water gun, high-pressure water is injected into the pipeline to flush out dirt and sediment on the pipeline wall. The water used to flush the pipeline is not reused, which causes a great waste of water resources and is not economical.

[0003] 2. Chemical cleaning method: Chemical cleaning method uses chemical agents to dissolve and remove dirt in the pipeline. Commonly used chemical agents include acidic and alkaline cleaning agents. However, this method has relatively high technical requirements, and improper operation can easily cause some chemical hazards. When using it, you need to pay attention to the concentration and method of use of the agent to avoid damage to the environment and pipelines.

[0004] 3. Mechanical cleaning method: Mechanical cleaning method is to scrape and remove the dirt in the pipe by using mechanical equipment, such as pipe cleaning machine and scraper. Mechanical cleaning method can effectively remove the scale and sediment in the pipe, but it is easy to cause damage to the pipe. It is necessary to pay attention to the selection of appropriate cleaning tools and operation methods.

[0005] All of the above three methods have their own shortcomings. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a tap water pipeline circulation flushing device, system and method, which solves the problem that the pipeline cleaning method in the prior art causes waste and affects water quality and pipeline equipment.

[0007] The present invention adopts the following technical solutions to solve the above technical problems: A tap water pipe circulation flushing device comprises a filter screen, an activated carbon filter, a circulation booster pump and a pressure gauge; the activated carbon filter, the filter screen and the circulation booster pump are arranged in sequence between two valves at the end of the pipe to be flushed, pressure gauges are arranged at both ends of the activated carbon filter and the filter screen, and the same pressure gauge is shared between the activated carbon filter and the filter screen.

[0008] The pipelines to be flushed at both ends of the valve are connected by non-engineering auxiliary pipes.

[0009] Both ends of the non-engineering auxiliary pipe are connected to the pipeline to be flushed through a tee.

[0010] The circulating booster pump is connected to an external water supply system.

[0011] When the pipeline to be flushed is a double pipe, the filter screen, activated carbon filter, circulating booster pump and pressure gauge are arranged on any one of the pipes, and the two pipes to be flushed are connected by a water pipe.

[0012] The activated carbon filter and filter screen are both detachable and recyclable devices.

[0013] The tap water pipe circulating flushing system comprises the tap water pipe circulating flushing device connected to the pipe to be cleaned, the circulating booster pump of the tap water pipe circulating flushing device is connected to an external water tank, and the external water tank is connected to a water truck.

[0014] It also includes an external control terminal, a pressure gauge and a circulation booster pump are connected to the external control terminal, and the external control terminal sends a control signal to the circulation booster pump according to the data of the pressure gauge.

[0015] The method for circulating and flushing a tap water pipeline comprises the following steps: Step 1: Connect each device of the water pipe circulation flushing system to the pipe to be cleaned, and adjust the initial value of each pressure gauge; Step 2: Start the circulating booster pump and monitor the pressure gauge values ​​at both ends of the activated carbon filter and the filter screen; Step 3: When the pressure gauges at both ends of the activated carbon filter or the filter screen are detected to be inconsistent, the circulating booster pump is stopped; Step 4: Replace the activated carbon filter or filter between the pressure gauges with inconsistent pressures; Step 5. Repeat steps 2 to 4 until the water pipe reaches the cleaning target.

[0016] The external control terminal is used to monitor the value of the pressure gauge in real time. When the pressure difference between any two pressure gauges exceeds the set threshold, the circulation booster pump is automatically stopped and the activated carbon filter or filter screen at the corresponding position is replaced.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This device adds a filter screen, an activated carbon filter, a circulating booster pump and a pressure gauge at the position of the pipeline valve to flush the pipeline. The filter screen can filter impurities in the pipeline, the activated carbon filter can adsorb harmful chemical components in the pipeline, and the circulating booster pump can make the water flow rate meet the design requirements.

[0018] 2. The pressure gauge is used to monitor whether the filter screen and activated carbon filter are blocked during the flushing process, and replace them in time when the pressure changes. This can reduce the input of personnel and machinery, increase the construction speed, shorten the construction period, save water resources and reduce construction costs.

[0019] 3. This device and system can also be connected to an external control terminal to automatically monitor the pressure value of the pressure gauge and automatically control the action of the circulating booster pump according to the pressure value, thereby improving the intelligence of the system, saving time and improving efficiency.
