Abstract

The invention relates to a boiler flue gas temperature adjusting device and an adjusting method thereof. A boiler comprises a mounting opening, an air inlet and an air outlet, the boiler flue gas temperature adjusting device comprises a flow guide heat exchange plate, a first temperature sensor and a controller, the flow guide heat exchange plate penetrates through and connects in the installationopening of the boiler and is located between an air inlet and an air outlet, the flow guide heat exchange plate can move in a reciprocating mode in the height direction and / or the width direction ofthe boiler, and can exchange heat with the flue gas; the first temperature sensor is used for monitoring the flue gas temperature on one side of the gas outlet to form a first flue gas temperature signal and sending the first flue gas temperature signal; the flow guide heat exchange plate and the first temperature sensor are both connected with the controller, the controller is used for receivingthe first flue gas temperature signal, the first flue gas temperature signal is compared with a preset temperature signal, and the flow guide heat exchange plate is controlled to move in a reciprocating mode according to the comparison result. According to the adjusting device and the adjusting method, the problem that the flue gas temperature of the boiler for treating the dangerous waste cannotbe adjusted is solved, and the temperature fluctuation of the flue gas is avoided.

Description

technical field [0001] The present invention relates to boiler equipment, more specifically, to a boiler flue gas temperature regulating device and method. Background technique [0002] When hazardous wastes are processed by boilers, due to the variety and complex composition, they may contain or generate dioxins. During the incineration process, most of them have been destroyed and decomposed. The substance will be discharged along with the exhaust gas, and will be catalyzed by metal chlorides to generate dioxins. If the exhaust gas temperature of the boiler is between 300°C and 400°C, it will provide convenient conditions for the formation of dioxins. Generally, the furnace temperature of the boiler should exceed 500°C so that the hazardous waste can be fully burned, and the exhaust gas temperature of the boiler may be as high as 550°C. Although it can curb the generation of dioxins, it will affect the subsequent treatment of the flue gas. For example, the bag filter may ...
