Embodiment Construction

[0025] Such as figure 1 As shown, the fixed bed slag gasifier of the present invention is used to process carbonaceous substances, and it consists of a raw material lock hopper 2, a raw material buffer bin 3, a furnace body 4, a control nipple 6, a slag quenching chamber 7, and a slag lock 8 and other parts. A composite furnace lining 10 is provided inside the furnace body 4 , the lower part of the furnace body 4 is equipped with a nozzle 49 , the upper end of the composite furnace lining 10 is provided with a gas collecting device 9 , and a slagging device 11 is installed under the furnace body 4 .

[0026] In the prior art, the furnace body is usually divided into three regions according to the temperature of the bed, such as figure 2 As shown in the lower area and the slag pool area 11, when the gasifier processes materials, the temperature of the materials in the furnace in this area is relatively high. Due to the intense exothermic reaction between the carbonaceous mate...

Abstract

The invention relates to a fixed bed slag gasification furnace. The inner wall of a furnace body (4) is provided with a composite furnace lining (10), the furnace body (4) is divided into a lower and slag bath region (11), an upper and middle region (12) and a top region (13), wherein the lower and slag bath region (11) is provided with a nozzle (49), the composite furnace lining (10) in the top region (13) is in a two-layer structure, the composite furnace lining (10) in the upper and middle region (12) is in a three-layer structure, and the composite furnace lining (10) in the lower and slag bath region (11) is in a four-layer structure. The invention has the advantages of reasonable design structure, good safety performance and good gasification effect and can solve the problems that furnace lining is seriously burnt and damaged, service life of the gasification furnace is short and gasification effect is poor in the prior art.

Description

technical field [0001] The invention relates to a molten slag gasification furnace, in particular to a fixed-bed molten slag gasification furnace for processing carbonaceous substances. Background technique [0002] In the prior art, a fixed-bed slag gasifier is usually used for processing carbonaceous substances, and the carbonaceous substances include solid raw materials and liquid raw materials. Solid raw materials can refer to solid carbonaceous substances with water content less than 45%, such as various high-quality coal, low-quality coal, inferior coal, peat, solid waste and solid carbon-containing biomass, etc.; liquid raw materials can refer to multi-component slurry, tar , residual oil, coal slurry and carbon-containing biomass slurry, etc. [0003] The gasifiers currently used in the mainstream coal gasification technology for large-scale industrial applications include pressurized gasifiers with fixed bed solid slagging, entrained flow coal slurry pressurized ga...
