The invention discloses a plasma gasifier melt interface monitoring device based on ultrasonic medium transmission characteristic difference. The monitoring device comprises a control system, a signal transmitting device and a signal receiving device, the control system is used for controlling the signal transmitting device to transmit an ultrasonic signal and simultaneously collecting the data of the signal receiving device, and acquiring the receiving time of an in-furnace transmission signal in each acquisition signal; the signal transmitting device is arranged on the outer side wall of the bottom of a plasma gasification furnace and is used for receiving an instruction sent by the control system and transmitting an ultrasonic pulse signal; the signal receiving device is mounted on the outer side wall of the plasma gasification furnace, is opposite to the signal transmitting device along the radial direction and is used for receiving the ultrasonic signals transmitted by the signal transmitting device. According to the invention, the height position from the melt in the plasma gasification furnace to the bottom in the plasma gasification furnace can be detected in real time, so that the feeding speed and the discharging speed can be controlled in time, and the garbage fly ash combustion efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of detection of the melting interface position of a high-temperature melting furnace, in particular to a monitoring device and a detection method for a melting interface of a plasma gasification furnace based on the difference in transmission characteristics of an ultrasonic medium. Background technique [0002] High temperature melting furnace is the basic industrial equipment in chemical industry. The interface position of the molten material in the furnace often affects the reaction process in the furnace, the control of the system feeding system and the slag handling system, and the detection of the interface position of the molten material in the furnace is one of the issues concerned in this field. For different furnace bodies, there is no universal method for detection methods, and for some special furnace environments of melting furnaces, such as high temperature, high pressure, complex furnace envir...
