Description

Cleaning device of matrix type air supply quantity measuring device Technical Field The utility model relates to the technical field of ash removal devices, in particular to a cleaning device of a matrix type air supply quantity measuring device. Background In the operation process of a power plant, the secondary air supply quantity of the boiler is a key parameter, and the secondary air supply quantity of the boiler needs to be accurately measured, otherwise, the control of the secondary air supply quantity is not standard, so that the combustion efficiency is affected, and even the environment is polluted. The air supply quantity measuring device is arranged in the secondary air pipe, and because the air sent by the air feeder usually contains impurities such as dust, the measuring device is easy to accumulate dust and block after long-time operation, and the accuracy of the air supply quantity measurement is seriously affected. Typically, a compressed air injection device is used to purge the sampling line of the measurement device. The device for measuring the secondary air supply quantity of the partial boiler adopts an inverse strong wind compensation type matrix measuring device, the middle part of a vertical rod of the measuring device is fixed on a supporting rod, the device is provided with ten sampling holes and is provided with a compensation type anti-blocking probe, and in theory, the design can effectively prevent dust accumulation and blocking during air quantity measurement. However, in actual operation, the device does not completely solve the problem of dust accumulation due to the high dust content in the air supply system.
