Abstract

Provided is a biomass fuel boiler device and a working method of the biomass fuel boiler device. The device is characterized in that a motor in a power chamber drives a transmission shaft to rotate, and the transmission shaft in a transmission chamber is of a cavity structure with through holes in the surface; an inner cavity of the transmission chamber communicates with the outside through a gasinlet pipe, a fresh air path driven by a mixing motor to rotate is arranged in a mixing chamber, and a mixing shaft is rotationally arranged in an inner cavity of the fresh air path; through holes areformed in the surface of the fresh air path, meanwhile the surface of the fresh air path is fixedly connected with gas disturbance blades, and the upper end and the lower end of the mixing shaft arecorrespondingly and fixedly connected with a gas inlet pipe of a rotary spray head and the upper end of the transmission shaft; and through holes are formed in the lower surface of a converging chamber at the upper end of the mixing chamber, a catalyst spray nozzle is connected to the lower portion of the mixing chamber, and the exterior of the gas inlet pipe of the rotary spray head is connectedto the upper opening end of the converging chamber through a bearing. The method comprises the steps that the rotary spray head is controlled to rotate, or meanwhile the gas disturbance blades are controlled to rotate, and a catalyst is introduced. The device and method are good in disturbance effect, and the heating efficiency of a boiler can be improved.

Description

technical field [0001] The invention relates to a biomass fuel boiler device and a working method thereof, belonging to the field of boiler equipment. Background technique [0002] In recent years, with the rapid development of the national economy, the boiler industry using biomass as fuel has achieved rapid development. With the increase in the number of industrial furnaces and the improvement of product processing quality requirements, the matching airflow disturbance device Need to meet the technical requirements of different standards such as large flow. Nowadays, in the process of processing biomass fuel boilers, it is necessary to exhaust air into the furnace body through the airflow disturbance device for heating. However, the flow rate of the current airflow disturbance device is too low to make the temperature in the furnace rise rapidly, resulting in the heating efficiency. reduce. Contents of the invention [0003] Aiming at the problems existing in the above...
