Problems solved by technology

Due to the high-speed and high-temperature flue gas, the water pipe on the windward side wears quickly. When the water pipe leaks, trachoma, or cracks, the internal water seeps or sprays out, and immediately vaporizes in this high-temperature environment, and the vaporized water mist will dissipate the Dust deposits, which cause blockage of the flue
[0004] In view of this situation, the present invention provides a flue transducer protection method and device, that is, by adding a row of redundant protection pipes on the side of the transducer facing the flue gas, filling the protection pipes with pressure gas, and filling the protection pipes A pressure sensor is installed inside. When the protective tube is worn, leaking trachoma or cracks appear in the protective tube, the internal high-pressure gas is ejected, causing the internal air pressure to drop. Carry out maintenance and remedies, and at the same time, check the transducer tubes in the vicinity to avoid wear and tear on the transducer tubes in the same part after long-term work, resulting in blockage of the flue

Abstract

The invention belongs to the technical field of transducer protection, and particularly relates to a method and a device for protecting a flue transducer. A row of redundant protection pipes are additionally arranged on the surface, facing flue gas, of the transducer, and are filled with pressure gas; a pressure sensor is mounted inside each protection pipe; when the protection pipes are abraded and leakage sand holes and cracks are formed in the protection pipes, high-pressure gas inside the protection pipes is sprayed out to cause the reduction of internal gas pressure; the pressure sensors measure the pressure change so as to determine that the protection pipes have leakage faults, and the protection pipes are timely maintained and repaired; meanwhile, transduction pipes in a nearby region are checked, so that flue blockage caused by the abrasion of the transduction pipes at the same part after long-time working is avoided.

Description

Technical field [0001] The invention belongs to the technical field of transducer protection, and particularly relates to a method and device for protecting a flue transducer. Background technique [0002] The instrument or device used to realize the mutual conversion of different forms of energy can be generally called a transducer. For example, the audio electric signal is converted into audible sound, or the audible sound is converted into audio electric signal to realize the mutual conversion of electric energy and sound energy. Electroacoustic transducers, such as speakers (speakers), earphones, microphones, etc. The heat exchanger is also known as the heat exchanger, and it is also a kind of energy converter. It has the characteristics of small heat transfer resistance and large heat transfer capacity with enhanced heat transfer measures. It is a key equipment for rational utilization and saving of existing energy and the development of new energy. Widely used in dry petro...
