Description

A kind of heat accumulating type tar disposition burner

Technical field

The utility model is related to a kind of combustion apparatus, and in particular to a kind of combustion apparatus that can handle tar in combustion gas.

Background technology

During the processing of stalk integrated gasification and its process similarity, the combustible gas of institute's output includes a certain amount of coke Oil, in this case tar be thoroughly mixed with fuel gas in gaseous state.

Tar ingredients are complicated, and processing is difficult, if not handling tar, directly burn, tar can not decompose, after discharge Condense into liquid again when less than 200 DEG C, the tar of liquid is in black viscous liquid, is easy mixed with other ash contents and water Aggregation is closed, blocks follow-up air duct or burning appliance, tiny coke tar particles will produce the particles such as carbon black in burning, to rear Afterflame gas causes very big damage using equipment, and can form black smoke after combustion gas discharge pollutes.

The energy of tar accounts for about the 10% of gross energy, if being expelled directly out the gasification efficiency that can reduce the processing of stalk integrated gasification.

Kind of a mode is mainly the following to the processing of tar at present：

Physical partition method：First tar is converted to liquid from gaseous state, by the method washing or filter by tar from gas Then middle separation is used as waste to handle, on the one hand this method wastes the energy of tar, and still further aspect tar processing is improper It can cause seriously to pollute

Catalystic pyrolysis：Enter cat-cracker with the combustible gas of tar after gasification, carry tar at this time can Combustion gas can be reduced to 600 DEG C, and external heat source keeps cat-cracker at 750 ~ 900 DEG C, the catalyst in cat-cracker Under the action of so that catalytic cracking of tar reaches 99% or more, and this method system is complicated, and pyrolysis furnace interior conduit easily blocks, fortune Row requires high.

Invention content

The utility model proposes a kind of heat accumulating type tar to dispose burner, and simple in structure, deft design can efficiently use Calory burning removes the tar mixed in fuel gas.

The utility model solves the problems, such as that background content is proposed by the following technical programs：

Including：Reticular structure is wrapped up in cylinder, catalytic thermal storage ball, catalysis net, gas pipeline, the catalytic thermal storage ball outside, The catalysis net is located at inner barrel with gas pipeline, and catalysis net top is connected with gas pipeline lower part, and gas pipeline runs through cylinder Body top is connected with the cylinder external world, and the catalysis net lower part is connected through cylinder with the cylinder external world, the reticular structure and catalysis Net is that same coke tar cracking is catalyzed material composition, and the catalytic thermal storage bead is constituted with coke tar cracking catalysis material.

The cylinder side top is equipped with air inlet.

The inner barrel is embedded with refractory brick, and thermal insulation material is wrapped up outside cylinder.

The cylinder body bottom is equipped with admission line, and described admission line one end is connect with cylinder body bottom, the other end and air blast Machine connects.

Ignition tip is equipped in the gas pipeline.

Fig. 2 is the overlooking structure diagram that a kind of heat accumulating type tar of the utility model embodiment disposes burner.

Fig. 3 is the structural schematic diagram of catalytic thermal storage ball in the utility model embodiment.

Specific implementation mode

A kind of embodiment of the utility model is described in detail in conjunction with Fig. 1, Fig. 2, Fig. 3.

The present embodiment is to solve the above problems by the following technical programs：A kind of heat accumulating type tar disposition burner

Including：Cylinder 2, catalytic thermal storage ball 3, catalysis net 4, gas pipeline 5, catalytic thermal storage ball 3 is using SiO2 as matrix, outside Reticular structure 9 is wrapped up in portion, and catalysis net 4 is located at inner barrel, 4 top of catalysis net and 5 lower part phase of gas pipeline with gas pipeline 5 Even, gas pipeline 5 is connected through 2 top of cylinder with 2 external world of cylinder, and 4 lower part of catalysis net is connected through cylinder 2 with 2 external world of cylinder, Reticular structure 9 is that same coke tar cracking is catalyzed material composition with catalysis net 4.

2 side top of cylinder is equipped with air inlet 1.

Inner barrel is embedded with refractory brick, on the one hand reinforces cylinder, and still further aspect prevents long term high temperature operation from being made to cylinder At damage, package thermal insulation material prevents energy leakage, inside from cannot keep high temperature outside cylinder.

2 bottom of cylinder is equipped with admission line 7, and 7 one end of the admission line is connect with 2 bottom of cylinder, the other end and air blast Machine 8 connects.

The fuel gas of tar is carried by being ignited when ignition device, generates heat, catalytic thermal storage bead passes through After accumulation of heat, cylinder body temperature is maintained at 800 ~ 900 DEG C, and at this temperature, the combustible gas for carrying tar enters cylinder elder generation and urges Change regenertive small ball contact, catalytic thermal storage bead is with SiO₂It, being capable of catalytic tar cracking as the tar composite catalyst of matrix For fuel gas, the reticular structure of nickel-base material is enclosed on catalytic thermal storage bead, catalysis net equally uses nickel-base material, Ni-based Material also can effectively accelerate coke tar cracking as tar catalyst, and the combustible gas for carrying tar from top to bottom, is first stored with catalysis Hot bead comes into full contact with, and enters back into the catalysis net of lower section, and tar is all cracked into fuel gas, enters combustion by catalysis net Feed channel mixes under the action of admission line and air blower with outside air, is discharged after being lighted by electric ignition device.
