Embodiment 1

[0042] Such as figure 1 , figure 2 , image 3 and Figure 4 Commonly shown, an energy-saving and environment-friendly chain furnace, including a gasification device 1, the gasification device 1 is arranged on the upper part of the grate 3, and the gasification device 1 blows combustion-supporting air to the grate 3 from top to bottom.

[0043] The gasification device 1 is arranged at the front arch 2, and the front arch 2 is provided with an open chamber for accommodating the gasification device 1. The open chamber for placing the gasification device 1 includes a bottom wall 11 and a side wall 12. The bottom wall 11 It is arranged horizontally, and the side wall 12 is arranged vertically.

[0044] The gasification device 1 has an air inlet and an air outlet, the air inlet of the gasification device 1 is connected with the combustion-supporting fan, and the combustion-supporting fan is arranged outside the chain furnace, and the air inlet of the gasification device 1 can al...

Embodiment 2

[0057] Depend on Figure 8 and Figure 9 As shown together, a kind of energy-saving and environment-friendly chain furnace in the present embodiment has basically the same structure as that in Embodiment 1, and its difference is:

[0058] A plurality of first holes 711 , a plurality of second holes 712 and a plurality of third holes 713 are arranged in rows and evenly distributed on the side wall of the casing 71 . The first hole 711, the second hole 712 and the third hole 713 are all provided with two rows. on the side walls. The bottom of the tail end of the housing 71 is also provided with a long hole 714 for unloading.

Embodiment 3

[0060] Depend on Figure 10 , Figure 11 and Figure 12 As shown together, a kind of energy-saving and environment-friendly chain furnace in the present embodiment has basically the same structure as that in Embodiment 1, and its difference is:

[0061] The fly ash conveying auger 7 includes a housing 71 and a screw shaft 72 rotatably arranged in the housing 71 . The casing 71 is arranged in an arc shape and is semicircular. The screw shaft 72 includes a plurality of shafts 721 connected in sequence, and two adjacent shafts 721 are connected by a universal joint 722 . The fly ash conveying auger 7 of this structure has a compact structure and can adapt to the arrangement of different spatial structures. A first hole 711 , a second hole 712 and a third hole 713 are sequentially provided on the housing 71 from bottom to top. There are multiple first holes 711 , second holes 712 and third holes 713 , and the diameters of the holes increase sequentially. The plurality of firs...

Abstract

The invention discloses an energy-saving and environmentally-friendly chain furnace which comprises a gasification device and a fly ash unit; the gasification device is arranged at the upper part of afire gate, blows combustion-supporting air to the fire gate from top to bottom and is arranged at a front arch, an open chamber for accommodating the purification device is formed in the front arch,and the gasification device blows the combustion-supporting air to the fire gate from top to bottom; the fly ash unit is positioned in a position at the rear end of the front arch and is used for blowing fly ash into a furnace body, so that coal and the fly ash in the chain furnace are fully burned, therefore, the coal conversion efficiency is higher, the waste of coal resources cannot be caused,and the pollution caused by harmful gas produced by insufficient combustion of the coal to an environment is reduced; the chain furnace is simple in structure and convenient to use, thereby being an energy-saving, efficient and environmentally-friendly novel chain furnace.

Description

technical field [0001] The invention relates to a new boiler, in particular to an energy-saving and environment-friendly chain furnace, which belongs to the technical field of boiler equipment. Background technique [0002] The chain furnace is a layer combustion furnace with a high degree of mechanization. It is named for its grate similar to a chain crawler. It is a kind of furnace-type combustion equipment widely used in industrial boilers. The chain furnace is a chain furnace, which is a kind of layer combustion furnace and belongs to the mechanical combustion grate. Working principle: Drive the chain grate to rotate through the reducer, so that the coal is ignited from the front and burns out at the end of the boiler. Compared with the fixed grate, the combustion efficiency can be improved. At the same time, when the chain turns to the bottom, the air cooling can protect the grate from burning damage. It is a better combustion equipment in the layer combustion furnac...
