Embodiment 1
[0012] As shown in the figure, an intermittent high-pressure strong-flow gas jet descaling device includes a jet generator 3, an air supply hose 5, a guide tube 8, a pressure-stabilizing chamber 11, three compressed gas cylinders 15, a cavity 16, Connecting sleeve 18, sealing ring 19, piston 20, rear shell 21, sealing ring 22, filter 23. Such as figure 1 As shown, the compressed gas cylinder 15 is a conventional high-pressure gas cylinder (usually a 150atm gas cylinder), and the outlet of the gas cylinder adopts a conventional connection, and is connected with three shut-off valves 13 through a high-pressure hose 14 to prevent gas from entering the gas cylinder in reverse, and the cut-off The valve 13 and the plenum chamber 11 are threadedly connected with a sealing ring. A pressure gauge 12 is installed at the outlet of the plenum chamber 11 to control the working air pressure. The air supply hose 5 is connected to the tail of the jet generator 3. The jet generator 3 There i...

The invention relates to an intermittent high pressure high current gas jet scale removing device, comprising a jet generator, a guiding rope, a cut-in sleeve, a flexible pipe, a guiding rope end cover and a guiding pipe. A compression gas cylinder is connected with a voltage stabilizing chamber by virtue of the flexible pipe and a check valve, the voltage stabilizing chamber is connected with the flexible pipe, the flexible pipe penetrates through the flexible pipe end cover to be connected with the tail of the jet generator, the front end of the jet generator is connected with the guiding rope, the guiding rope penetrates through the guiding rope end cover, and the guiding rope end cover and a flexible pipe end cover are fixed at the opening of a pipeline. A high pressure gas cavity is connected with a rear case by virtue of a connecting sleeve. The invention has the advantages that: structure is compact and simple, universality is strong, applicability is high, cost is low, scale removing efficiency is high, and no pollution can be produced to the ecological environment and human body.
Description
technical field [0001] The invention belongs to pipeline descaling technology, in particular to an intermittent high-pressure strong-flow gas jet descaling device. Background technique [0002] The pipes used in industrial and civil fields for conveying raw materials, sewage discharge and circulating water cooling will reduce the effective working section due to the adhesion of sediment, dirt and water scale after a certain service period, thus reducing the efficiency. It may even lead to safety accidents. With the rapid development of my country's industry, the cleaning of pipeline dirt in chemical industry and metallurgical industry equipment is becoming more and more popular and more important. Therefore, this type of pipeline must be descaled regularly. Currently, the commonly used decontamination methods mainly include: manual cleaning, chemical cleaning, high-pressure water jet cleaning, and recently blasting cleaning. However, the above methods are time-consuming, l...
