Description

TECHNICAL FIELD

[0002] In the production of coal chemical industry, petroleum chemical industry, machining, papermaking and sugar making and textile building material industries, corresponding material characteristic detection probes are often installed, such as concentration probe, temperature and pressure probe or component monitoring probe, to monitor the characteristics of process materials in real time. However, the materials involved in the production of these industries will have special properties: viscous, easy to adhere, high melting point, many and complex impurities, and easy to solidify at low temperature. This leads to the fact that the online monitoring probe is easily attached or covered by the material during actual production, causing the monitoring probe to deviate, be abnormal or even fail.

[0003] In use, to maintain the normal operation of the probe detection, the common method on the market is to flush the probe with gas or liquid, or to use ultrasonic coupling for secondary cleaning, or to use a mechanical scraper for cleaning. However, these technical means are almost ineffective in cleaning viscous oil materials such as tar, heavy oil and syrup. Instead, the probe needs to be removed from the equipment pipeline by maintenance personnel, cleaned and reinstalled. In the case of a large number of probes in a factory, this is a heavy burden for the enterprise. In addition, some cleaning techniques that use a large amount of high-temperature steam to flush the probe can cause some heat-sensitive materials to decompose at high temperature after being heated for a long time, causing the materials to denature. In severe cases, it can even endanger the safe operation of the factory production. Therefore, we need to provide a micro jet saturated steam probe cleaning device. UTILITY MODEL CONTENTS
