Flue gas temperature detection device for boiler burning and using method thereof

Abstract

The invention discloses a flue gas temperature detection device for boiler burning and a using method thereof. The flue gas temperature detection device comprises a pipeline, a fixing column, a partition plate, a driving mechanism, a mounting mechanism, a dismounting mechanism and a cleaning mechanism, and the bottom of the interior of the pipeline is fixedly connected with a fixing shaft. The device has the beneficial effects that the device is novel in structure and convenient to operate; practicality is high; by adding the fixed column, the partition plate, the through hole, the temperature sensor and other structures to be used in cooperation, the temperature of the flue gas at different positions in the pipeline can be measured in a concentrated mode, the temperature detection accuracy is improved, and impurities in the flue gas entering the fixed column can be filtered out by adding a filter screen; and impurities are prevented from being adsorbed on a detection rod of the temperature sensor to influence the detection accuracy, the cleaning mechanism is added to facilitate cleaning of the outer side of the filter screen through a brush and prevent the filter screen from being blocked by the impurities, the dismounting mechanism is added to facilitate quick dismounting and maintenance of the temperature sensor, and the dismounting efficiency of the temperature sensor is improved.

Description

technical field [0001] The invention relates to the technical field of temperature detection devices, in particular to a flue gas temperature detection device for boiler firing and a method for using the same. Background technique [0002] The boiler furnace is a coal-fired boiler that uses the air in the air chamber to blow the hot material layer on the fixed grate or chain grate into a boiling state, so that it rolls up and down with the coal particles and burns. Referred to as boiling furnace. Also known as fluidized bed combustion boiler. The exhaust gas temperature needs to be monitored during the combustion adjustment and flue gas environmental protection detection of the boiler burner. The existing temperature detection device uses a temperature sensor to measure the flue gas temperature inside the pipe, but the pipe is too large and the temperature sensor measures The range is too small to accurately measure the flue gas temperature inside the pipe, and the flue ga...

The exhaust gas temperature needs to be monitored during the combustion adjustment and flue gas environmental protection detection of the boiler burner. The existing temperature detection device uses a temperature sensor to measure the flue gas temperature inside the pipe, but the pipe is too large and the temperature sensor measures The range is too small to accurately measure the flue gas temperature inside the pipeline, and the flue gas contains a lot of impurities, which will be adsorbed on the outside of the detection rod after long-term use, resulting in inaccurate temperature values
