Embodiment 1

[0025] Such as figure 1 As shown, a biomass pyrolysis gasification furnace with a star-shaped combined structure includes a main furnace 3, and the main furnace 3 is correspondingly connected with at least one auxiliary furnace 2. On the main furnace 3, at least one circular The cylinder connecting pipe 1 is provided with a conical cylinder connecting pipe 4 on the auxiliary furnace 2, and each cylindrical connecting pipe 1 is matched with a corresponding conical cylinder connecting pipe 4. The present invention is a kind of star combination structure The main furnace 3 in the biomass pyrolysis gasification furnace uses biomass energy blocks with high calorific value to generate combustible gas, and the flame generated is used to start multiple parallel auxiliary furnaces 2, so that the types of biomass raw materials in the auxiliary furnace 2 and humidity are changed, and biomass fuel with high water content can be processed without pretreatment. The high-temperature flue gas...

Embodiment 2

[0032] Such as figure 2 As shown, in this embodiment, the similarities with Embodiment 1 will not be repeated. The difference is that in this embodiment, a star-shaped biomass pyrolysis gasifier with a main furnace connected in parallel and four auxiliary furnaces is adopted. It can mainly process a large amount of biomass raw materials.

[0033] The present invention adopts a small-volume main furnace 3, which is connected with four relatively large-volume auxiliary furnaces 2 through connecting pipes to form a star-shaped pyrolysis gasification furnace with one drive and many. Combustion of high calorific value energy blocks in the main furnace 3 generates high-temperature gas, and then respectively ignites the combustible gas in the gap between the cylindrical connecting pipe 1 and the cone connecting pipe 4, thereby starting the annularly connected auxiliary furnace 2. According to the needs of the actual situation, then through the closing of the end caps of the cylindr...

Abstract

The invention discloses a biomass pyrolysis gasification furnace of a star composite structure. The biomass pyrolysis gasification furnace comprises a main furnace. The main furnace is correspondingly and cooperatively connected with at least one auxiliary furnace. At least one cylinder connecting pipe is arranged on the main furnace. Each auxiliary furnace is provided with a cone connecting pipe. Each cylinder connecting pipe is correspondingly and cooperatively connected with the corresponding cone connecting pipe. A main furnace slag discharging opening is formed in the bottom of the main furnace, and a main furnace air blower is arranged above the main furnace slag discharging opening. A main furnace grate is arranged above the main furnace air blower, an ignition opening is formed above the main furnace grate, and a main furnace feeding hopper is arranged on the top of the main furnace. By means of the biomass pyrolysis gasification furnace of the star composite structure, the main furnace and the multiple auxiliary furnaces of the same structure are adopted, a furnace body combination of the star structure is achieved, the main furnace drags the several parallel auxiliary furnaces to achieve efficient pyrolysis, meanwhile, the main furnace and the auxiliary furnaces are all small in size, and therefore manufacturing, transporting, construction, installation and later-period maintenance cost is relatively low.

Description

technical field [0001] The invention relates to the field of gasifiers, in particular to a biomass pyrolysis gasifier with a star-shaped combined structure. Background technique [0002] At present, biomass pyrolysis and gasification technology mainly uses low-oxygen combustion of some biomass materials, and then uses the heat and residual oxygen of the flue gas to pyrolyze and gasify the rest of the biomass materials. The main structure is to use a single gasification furnace for upper feeding or side feeding, and the external high-temperature flue gas is injected into the furnace to achieve high-temperature pyrolysis of biomass and generate flammable gas. Usually this kind of gasification furnace is bulky and requires external heat supply, especially when the temperature in the furnace is unstable and cannot reach the stable pyrolysis temperature, an external heat source needs to be provided. [0003] There are mainly three types of gasifiers in the prior art, such as cyc...
