Description

Waste gas burning treatment device

Technical field

The utility model belongs to electronic kiln auxiliary auxiliary facility technical field, and in particular to a kind of waste gas burning processing dress Put, for by electronic kiln, caused flue gas burning to be handled in electronic product sintering process.

Background technology

Foregoing electronic product is main but is not limited to species exemplified below；Ceramic condenser PZT (piezoelectric transducer), ceramics Wave filter, ceramic heat-sensitive electronic component, ceramic inductance substrate, ceramic dielectric substrate, MIN workpiece（Metal dust injection molding work Part）, LiFePO 4 powder and all kinds of use for electronic products powder, etc..

As is known in the industry, in order to make powder compression molding, PVI or PVA is added generally into powder in compounding process Suppressed Deng organic colloid, then by mould, obtain moulded blank.Equally, needed before metal dust injection molding workpiece is prepared pair Used powdered or granular material mixing, specifically, uses adhesive（Also referred to as " binding agent "）With powdered or graininess Material mixing, after mixing with spray regime introduce injection molding mould, obtain moulded blank.

And then as is known in the industry, added during moulded blank introduces electronic kiln high temperature sintering, during previous batch mixing Adhesive into raw material is discharged in the form of glue flue gas, if glue flue gas not being acted upon and being immediately discharged to the external world, that Atmospheric environment can be certainly undermined, and harmful effect can be produced to plant and water system after soil and waters is fallen to, Or even undermine human health.

The positive effect of foregoing Waste gas burning treatment device is：The glue flue gas for coming from electronic product firing furnace is fired Burn, to meet qualified discharge requirement.The technical information of Waste gas burning treatment device can be seen in disclosed Chinese patent literature, As CN101749717B recommend have " emission-control equipment of electronic kiln ", and for example CN105149587B be provided with " MIN workpiece burn Scrap rubber Flash Gas Compression Skid System of freezing of a furnace ", etc..This two patents for being not limited to enumerate are pot type burning processing device, pot type Though burning processing device has the strong point of small volume, disposal ability will be inferior very much compared to the oven-like structure of horizontally-arranged formula, and crouch The oven-like structure for putting formula is more suited to the electronics sintering furnace big with production capacity and matched.

Chinese patent Authorization Notice No. CN2697476Y, which is introduced, horizontal " electronic kiln waste gas burner ", the patent To electronic kiln, the caused scrap rubber gas during to electronic product sintering has good disposal ability and objectively to scheme The strong point of three aspects of its row of Instructions Page 2 the 13rd to 14 conclusion can be cashed.But the CN2697476Y still exist with Lower deficiency：First, due to having adhered to the design concept of electronics sintering furnace body and by glue smoke combustion furnace body（It is hereinafter referred to as " useless Smoke combustion furnace body "）Shape of cross section design it is rectangular, squarely, the shape of cross section of burner hearth are more precisely set Shape with flue gas combustion furnace body of heater is in the relation followed in sb's footsteps, i.e., is equally square, thus during the use of reality, There is air-flow to lose smooth or even dead angle be present, influence the burning treatment effect to flue gas；It is second, traditional due to having followed Design pattern and axial centre that flue gas is introduced to interface face burner hearth is introduced directly into burner hearth, but made through the applicant The experiment of non-finite number of time shows that this design method is unfavorable for making flue gas produce eddy flow, and flue gas is in combustion chamber i.e. in stove Residence time in thorax or the time contacted with hearth wall are of short duration, influence the harmful substance in flue gas such as benzene, toluene etc. Abundant burning-up effect；Third, due to by heat exchange mechanisms（Patent claims heat exchanger tube）Burner hearth rear portion is arranged on, by burner hearth rear portion still The flue gas of pipe is introduced into by way of outside air heat exchange of the heat exchange mechanisms i.e. in heat exchanger tube and the introducing electricity after heat exchange In sub- sintering furnace body, thus belong in stove and exchange heat, although heat exchange can obtain the preferable heat exchange to extraneous normal temperature air in stove Effect, but the heat consumption of burner hearth is big, is unfavorable for saving the energy.

For above-mentioned CN2697476Y Shortcomings, the applicant has made beneficial design and formd to hand over to be situated between below The technical scheme to continue.
