Abstract

The invention relates to an air pre-heater distance measuring device, and belongs to the technical field of air pre-heater air leakage control systems. The problems that most existing distance measuring devices for the air leakage control system of the air pre-heater are complex in structure and high in manufacturing cost are solved. The air pre-heater comprises an air pre-heater rotor, an air pre-heater fan-shaped plate and air pre-heater T-shaped steel, the air pre-heater T-shaped steel is arranged below the air pre-heater fan-shaped plate and fixed to the periphery of the air pre-heater rotor, the distance measuring device comprises a front end cover, a sensor, a mounting pipe and an acting block, the acting block is connected to the inner side of the air pre-heater T-shaped steel, the installation pipe is connected with the air pre-heater sector plate, the front end cover is arranged on the lower portion of the installation pipe, the sensor is arranged in the installation pipe, and a probe of the sensor penetrates through the front end cover and corresponds to the action block. The device is simple to install, convenient to maintain and low in cost, and effectively solves the problems of inaccurate data acquisition of the sensor and low air leakage input efficiency caused by a high-temperature dusty environment of the air pre-heater.

Description

technical field [0001] The invention relates to a distance measuring device, which belongs to the technical field of an air preheater control air leakage system. Background technique [0002] The air preheater, also referred to as the air preheater for short, is a preheating device that improves the heat exchange performance of the boiler and reduces heat loss. The function of the air preheater is to conduct the heat carried in the flue gas discharged from the tail flue of the boiler to the air before entering the boiler through the heat sink, and preheat the air to a certain temperature. At present, in the air leakage control system of the air preheater, there are many kinds of distance measuring devices, but most of the distance measuring devices are not suitable for high temperature environments, or have complex structures and high production costs. [0003] Based on the above problems, it is urgent to propose an air predictor ranging device to solve the above technical ...
