Problems solved by technology

[0002] When the existing hot blast stove is incinerated, its silo is connected with the furnace body through a screw conveyor, so that during the incineration process, some biomass particles are still retained in the screw conveyor, and when the sparks in the furnace body come into contact with the biomass particles When the temperature is high, the biomass particles trapped in the screw conveyor will be ignited to cause backfire, and come out from the feed port of the silo to cause a fire, causing unnecessary damage; and when the temperature is too high, stop feeding Oxygen will cause biomass particles to burn insufficiently and emit black smoke to pollute the environment, and do not stop adding oxygen. Because oxygen has a combustion-supporting effect, the combustion of biomass particles will be too vigorous, and the furnace temperature will be too high, so it is necessary to improve

Embodiment Construction

[0021] The following descriptions are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention. The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Examples, see Figure 1 to Figure 3 Shown: a biomass particle hot air stove, including a furnace body 10, a heating device and a silo 100, characterized in that it also includes a conveying pipe 30 and a screw conveyor 20, and the inlet of the screw conveyor 20 is connected to the silo 100 , wherein one end of the conveying pipe 30 is connected to the outlet of the screw conveyor 20, and the other end extends into the furnace body 10, wherein the inner wall of the conveying pipe 30 is smooth and the inclination angle with the horizontal direction is less than 90 degrees. The silo 100 enters the screw conveyor 20, and the motor 21 connected to the screw conveyor 20 controls the rotation of the screw ro...

Abstract

The invention discloses a biomass particle air heating furnace. The biomass particle air heating furnace comprises a furnace body, a heating device and a stock bin, and is characterized by also comprising a spiral conveyor and a conveying pipe; and the pipe wall of one end of the conveying pipe is connected with the outlet of the spiral conveyor, and the other end of the conveying pipe stretches into the furnace body. The biomass particle air heating furnace has the following characteristics: due to twice feeding, fire hazard is avoided, and unnecessary economic loss or personnel casualties are avoided; and due to twice oxygen conveying, the fact that the temperature of the furnace body is too high is avoided, complete combustion of the biomass particles is guaranteed, black smoke is avoided and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of hot blast stoves, in particular to a biomass particle hot blast stove. Background technique [0002] When the existing hot blast stove is incinerated, its silo is connected with the furnace body through a screw conveyor, so that during the incineration process, some biomass particles are still retained in the screw conveyor, and when the sparks in the furnace body come into contact with the biomass particles When the temperature is high, the biomass particles trapped in the screw conveyor will be ignited to cause backfire, and come out from the feed port of the silo to cause a fire, causing unnecessary damage; and when the temperature is too high, stop feeding Oxygen will cause insufficient combustion of biomass particles to emit black smoke and pollute the environment, and do not stop adding oxygen. Because oxygen has a combustion-supporting effect, the combustion of biomass particles will be too vigorou...
