Embodiment 1

[0035] Embodiment one: as attached Figures 1 to 2 As shown, it is only one embodiment of the present invention, a biomass gasification furnace slagging device, including a furnace body 1: the furnace body 1 is a columnar body with an open lower end; a slagging table 2: the slagging The platform 2 can rotate around its center. The slag discharge platform 2 includes a cone row 21 arranged above, a hollow slag discharge chamber 22 and a slag discharge rack 23 arranged below; the water tray 3: includes a water storage tray 31, an outlet A nozzle 32 and a drive frame 33 for driving the slag discharge table 2 to rotate.

[0036] In the above device, the size of the opening at the lower end of the furnace body 1 is the same as the size of the upper end of the slag discharge bin 22, and the upper end of the slag discharge bin 22 is circular, so the slag discharge bin 22 can effectively extend into the furnace body 1, and the furnace body 1 remains Airtight, the biomass raw material ...

Embodiment 2

[0039] Embodiment two: as attached Figures 1 to 3 As shown, it is only one embodiment of the present invention. After the residue is discharged into the water tray 3 , it is still necessary to further discharge the residue in the water tray 3 .

[0040] A slag discharge frame 23 is connected outside the slag discharge bin 22, and the slag discharge frame contacts with the inner wall of the water tray 22, and the residue in the water tray 3 is discharged from the water tray 3.

[0041] In the above solution, the number of slag discharge racks 23 is not less than 2, and the slag discharge capacity is enhanced.

[0042] In the above solution, the inner wall of the water storage tray 31 is provided with a rolling groove 34 for facilitating the rolling of the slag discharge rack 23 .

[0043] In the above solution, the slag discharge frame 23 is provided with a helical tooth 25 corresponding to the roll groove 34 .

[0044] The shape of the slag discharge rack 23 is helical and ...

Embodiment 3

[0046] Embodiment three: a kind of biomass gasifier slagging method, comprises the following steps:

[0047] S1. Fill the water tray with water to prevent the gas from leaking out of the furnace body;

[0048] S2, the slag discharge table rotates, and the residue in the furnace is introduced into the water tray through the slag discharge table;

[0049] S3. The slag discharge table drives the slag discharge frame to rotate on the inner wall of the water tray to take out the residue.

[0050] In the above method, all the water in the water tray is discharged regularly, and then water is injected again, and the height of the water surface does not exceed the slag discharge chamber in the slag discharge table.

[0051] In the above method, step S2 specifically includes: the slag discharge table is a hollow slag discharge table, and the upper part of the slag discharge table is conical, so that the residue enters the slag discharge table from the furnace body, and then rotates to...

Abstract

The invention provides a slag discharging device and method for a biomass gasifying furnace. The slag discharging device comprises a furnace body, a slag discharging table and a water disc, wherein the furnace body is a column with the opened lower end; the slag discharging table can rotate around the center thereof and comprises a cone row, a hollow slag discharging bin and a slag discharging frame, the cone row is arranged at the upper part of the slag discharging table, the hollow slag discharging bin is arranged at the lower part of the slag discharging table, and the slag discharging frame is connected with the hollow slag discharging bin; and the water disc comprises a water storage disc, a water outlet and a driving frame, and the driving frame is used for driving the slag discharging table to rotate. The slag discharging device is simple in structure, safe and stable and has a good slag discharging effect, the problem that the slag is difficult to be discharged after settling to be aggregated can be solved, and the airtightness of the gasifying furnace in the slag discharging process can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of gasifiers, [0002] In particular, the present invention relates to a slagging device and a slagging method for a biomass gasification furnace. Background technique [0003] With the dwindling reserves of traditional fossil energy (coal, oil, natural gas) and the environmental pollution caused by the use of fossil energy, which directly threatens the survival and development of human beings, it has become a priority for governments to attach importance to and develop renewable and environmentally friendly energy. consensus. Biomass is an organic substance produced by plants through photosynthesis. It is widely distributed, has a large amount of availability, is cleaner than fossil energy, and has the characteristics of zero carbon dioxide emissions. It is an important renewable energy source. Through thermochemical, biochemical and other methods, biomass can be transformed into clean gas or liquid fuels...
