Problems solved by technology

However, the design of the current straw gasification grate is not very reasonable. Because of its flat shape, the tar cracking area is small and the gas production is low.
Moreover, the grate is easily deformed and burned during use.
It not only increases the maintenance cost of the user, but also increases the labor intensity of the maintenance personnel; because it takes a long time to replace the grate each time, it affects the normal gas supply of the user

Embodiment 1

[0024] Depend on figure 1 -- Image 6 As shown, the straw gasification furnace grate assembly device of the present invention includes a conical grate 1, which is composed of a conical body 7 and a plane body 8, and has a conical basin structure as a whole. A round hole is respectively opened at both ends of the planar body 8, and the two ends of the rotating shaft 6 provided on the rotary grate 2 pass through the round holes respectively and are connected with the conical grate 1, and can rotate freely. 2 is a spherical sheet structure. A windshield 3 is arranged on the lower part of the conical grate 1, and the windshield 3 is a bucket-shaped structure with an upper opening and a lower part of the seal. There is a gap of 10cm between the bottom of the table-shaped fire grate and forms a closed area with the conical table-shaped fire grate. The windshield 3 is inserted on the furnace ring 9 and closely fits at an angle of 20° with the fitting of the furnace ring 9. One end...

Embodiment 2

[0026] The windshield 3 described in the present embodiment closely fits at an angle of 12° with the contact point of the conical fire grate 1, and the joint of the windshield 3 and the hoop 9 closely fits at an angle of 12°, and others are the same as in Embodiment 1.

Embodiment 3

[0028] The windshield 3 described in the present embodiment closely fits at an angle of 15° with the contact point of the conical fire grate 1, and the joint of the windshield 3 and the ring 9 closely fits at an angle of 15°, and others are the same as in Embodiment 1.

Abstract

This invention relates to a grate assembly apparatus for straw gasifier. The grate assembly apparatus comprises: an automatic transmission device and a cone-shaped grate. The cone-shaped grate is composed of a cone and a plane. Both ends of the plane comprise a hole. The rotary grate has a spherical lamellar structure, and both ends of the rotary axis on it stop run through the holes and are connected with the cone-shaped grate. A wind-shielding cap is set at the lower part of the cone-shaped grate, which is barrel shaped. The contact parts of the wind-shielding cap and the cone-shaped grate have 12-20 deg. angles, and are tightly fixed. One end of the rotary axis runs through the wind-shielding cap, and is connected with one end of the transmission shaft of the automatic transmission device. The grate assembly apparatus has such advantages as high coal tar cracking degree, high gas productivity, simple structure, and no deformation after a long time use.

Description

technical field [0001] The invention relates to a fire grate, in particular to a fire grate assembly device suitable for a straw gasification furnace. Background technique [0002] The straw gasification furnace is to carry out incomplete combustion and thermochemical reaction of organic combustibles such as straws under high temperature conditions in the furnace, so that the organic matter can be rapidly decomposed. The straw gasification furnace makes full use of renewable resources and has the function of energy saving and environmental protection. However, the design of the current straw gasification grate is unreasonable. Because of its flat shape, the tar cracking area is small and the gas production is low. Moreover, the grate is easily deformed and burned during use. It not only increases the user's use and maintenance cost, but also increases the labor intensity of the maintenance personnel; because it takes a long time to replace the grate each time, it affects t...
