Description

Technical Field

[0001] The utility model relates to the technical field of smoke detection, in particular to a smoke monitoring device for boiler combustion. Background Art

[0002] A boiler is an energy conversion device that converts the chemical energy of fuel combustion into thermal energy of steam or high-temperature water. In the combustion equipment part, the fuel combustion continuously releases heat and produces a large amount of high-temperature flue gas. The flue gas is finally discharged through the smoke exhaust device. Boilers are widely used in production and life in modern society. Most of the existing boilers that use coal, oil or biomass as fuel are difficult to meet the requirements of the "Boiler Air Pollutant Emission Standards", especially when the fuel is not fully burned. The pollution is more serious. This requires flue gas monitoring when the boiler flue gas is emitted.

[0003] Application No. 202021745945.3 discloses a flue gas monitoring device for boiler combustion, including a monitoring tube, a shunt tube, a motor, a solar panel, a filter element and an exhaust fan. The shunt tube is located on one side of the monitoring tube, and the solar panel is located on one side of the monitoring tube. The monitoring tube includes an air inlet, a first exhaust port and a protective cover. The air inlet is located at the bottom of the monitoring tube, and the first exhaust port is located at the top of the monitoring tube. A smoke gas detector and a temperature sensor are provided on the inner side of the air inlet. A battery, a controller and a data transmitter are provided inside the monitoring tube. The motor is located on one side of the first exhaust port, and a baffle is provided on one side of the motor. The shunt tube includes a shunt port and a second exhaust port. The shunt tube is located on one side of the monitoring tube, and the second exhaust port is located at the top of the shunt tube. The filter element is located on one side of the shunt port, and the exhaust fan is located on one side of the second exhaust port. The utility model not only has the characteristics of facilitating the monitoring of boiler flue gas emission quality and intelligent filtering emissions, but also has the effect of facilitating energy saving and electricity storage.

[0004] However, when filtering substandard flue gas, the device uses a filter element for filtering. However, the filter element of the device is located inside the diversion pipe, which makes it difficult to easily replace the filter element when it needs to be replaced, thereby affecting the filtering effect of the flue gas.

[0036] The implementation principle of a flue gas monitoring device for boiler combustion in the embodiment of the present application is as follows: the flue gas monitoring device for boiler combustion, by opening two corresponding front and rear sliding grooves 106 on the surface of the exhaust pipe 105, allows the slide plate 107 to be placed inside the exhaust pipe 105 for sliding, and the surface of the slide plate 107 is provided with two first empty grooves 108 and second empty grooves 109 of the same size, but the inner wall of the second empty groove 109 is installed with multiple brackets 110 for placing and supporting the filter element 111.
