Embodiment 2
[0023] The nitrogen pulse heat cleaning system of the present embodiment is a combination of nitrogen vehicles, hot washers, pulse control systems, adjustable, safe, environmentally friendly, and reliable. The system can generate the two-phase flow of the pulsating frequency adjustable gas-liquid, and the alternating mix of the liquid and gas is realized by controlling the solenoid valve and pulse valves, and the gas-liquid two-phase flow is automatically adjusted under the pulsating pressure and pulsating flow. With controllable adjustment, the efficiency of gas-liquid mixing is improved. Form a controllable pulse physical shock wave, oscillating, peeling, rust, by the thermal energy replacement of the pulse two-phase flow, the molter tube wall oil, wax, etc., to the cleaning purpose.
[0024] Nitrogen is filtered, separated, purified, purified by nitrogen membrane, and raised high-pressure nitrogen gas with a conventional outlet temperature of about 50 ° C to a high-temperature ...

Abstract
The invention provides a nitrogen pulse thermal cleaning system, which belongs to the technical field of thermal cleaning systems. The invention comprises: a pneumatic system, a hydraulic system, a pulse generator, a back pressure valve, a pressure transmitter and an outlet oil valve, the outlet of the pneumatic system is connected with the gas inlet of the pulse generator, the outlet of the hydraulic system is connected with the pulse generator The liquid inlet of the generator is connected, the outlet of the pulse generator is connected with the inlet of the back pressure valve, the outlet of the back pressure valve is connected with the inlet of the pressure transmitter 1, the outlet of the pressure transmitter 1 is connected with the outlet oil non The inlet is connected, and the outlet of the outlet oil nonane is connected with the pipeline to be cleaned. The nitrogen pulse thermal cleaning system can generate a gas-liquid two-phase flow with adjustable pulsation frequency. By controlling the solenoid valve and pulse valve to realize the alternate mixing of liquid and gas, the gas-liquid two-phase flow can be achieved under pulsating pressure and pulsating flow. The automatic and controllable adjustment of the flow improves the efficiency of gas-liquid mixing and the automation level of on-site operations.
