Description
Technical field
The utility model relates to the smoke evacuation dust arrester, relates in particular to the fume extractor in Equipment for Heating Processing field.
Background technology
Contain various attachments such as antirust oil, quenching oil, cutting fluid, cleaning agent because of item for disposal in the Equipment for Heating Processing; When heating, can produce a large amount of flue gases; Discharge out of the furnace if these flue gases are untimely, or can influence furnace atmosphere, cause product quality bad in the stove accumulated; Or can mix the generation blast with air; Or flue gas decomposes the generation carbon black under the meeting Yin Gaowen, is deposited on the heater, causes heater to damage, therefore must be in time with heating the flue gas discharge that produces.
The discharge of heat treatment flue gas must solve the problem of flue gas cool-down and flue gas flow; Heat treated flue-gas temperature is from 150 ℃～700 ℃ even higher; Directly exhaust has high requirements to the heatproof of air exhauster; If follow-up need the recycling flue gas is also very high to the heatproof requirement of flue gas retracting device.In addition, if flue gas blower fan capacity is too big, will influence the temperature homogeneity in the stove, this has just brought difficulty to selection of fan, requires the air quantity can not be too big.Also have,, run up to a certain degree, at a certain temperature, pipeline can occur and catch fire because the oily matter in the flue gas can deposit in pipeline.
Based on above reason, generally do not adopt the in line mode of blower fan in actual the use, but the principle that adopts negative pressure to pull out wind is discharged fume indirectly.Negative pressure pull out wind mechanism generally by ajutage, draw (pulling out) airduct and discharge pipe is formed, ajutage is connected with blower fan, induced duct links to each other with the stove exhaust outlet; Ajutage is nested in the induced duct, and the gas that blower fan produces flows in ajutage, can be at the terminal negative pressuren zone that produces of ajutage; This negative pressuren zone also is the outlet of induced duct, therefore, utilizes the negative pressure can be with the flue gas intake line; So both can utilize the negative pressure air draught; Realize the low discharge air draft, can will discharge flue gas cool-down through blower fan again, thereby avoid the problem of high temperature.
But this way still has some shortcomings, and at first, the gap of ajutage and induced duct is wayward, device excesssive gap or too small, and negative pressure will be very little, can not inhale flue gas; Secondly,, possibly cause against the wind if the device resistance to flow output is excessive, not air draft of blower fan but in stove jar wind, this is a danger close.Once more, also can occur the deposition of flue gas oily matter in the pipeline, cause the inner and outer pipes exhaust clearance more and more littler, finally lose scavenging action, blast pipe can only be scrapped.
