Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model smelting furnace exhaust treatment system.
Fig. 2 is the structural representation of this utility model smelting furnace tail gas pretreatment shunting heat abstractor.
Detailed description of the invention
As depicted in figs. 1 and 2, smelting furnace exhaust treatment system of the present utility model, including pulsed jet cloth filter 20, tail gas absorber 40 and concrete chimney 50, coupled together by pipeline between pulsed jet cloth filter 20, tail gas absorber 40 and concrete chimney 50, first pass around pulsed jet cloth filter 20 from the tail gas of smelting furnace discharge and carry out dust removal process, discharge from concrete chimney 50 after tail gas absorber 40 purifies the most again.Owing to pulsed jet cloth filter 20 and tail gas absorber 40 belong to prior art, therefore repeat no more in this article.
This utility model also includes that pretreatment shunts heat abstractor 10, pretreatment shunting heat abstractor 10 is arranged between smelting furnace and pulsed jet cloth filter 20, pretreatment heat radiation part flow arrangement 10 includes casing 11, the side of casing 11 is provided with air inlet pipe 12, the tail gas discharged from smelting furnace enters in casing 11 from air inlet pipe 12, the opposite side of casing 11 is provided with escape pipe 15, enters in pulsed jet cloth filter 20 from escape pipe 15 from casing 11 expellant gas；Casing 11 is internal is separated into multiple chamber by vertical clapboard, it is interconnected between two adjacent chambers, the top of casing 11 has been arranged side by side multicomponent flow heat dissipation pipeline, every component flow heat dissipation pipeline is made up of multiple U-tube 13, the two ends of U-tube 13 respectively with two adjacent chamber, first gas be diverted to each component flow heat dissipation pipeline after entering casing 11, flows into the most successively in each U-tube 13 of every component flow heat dissipation pipeline, until gas is discharged from the escape pipe 15 of casing 11；The lower section of casing 11 is disposed with multiple hopper 14, and dusty gas is when flowing through each U-tube 13 and carrying out shunting heat radiation, and part dust falls in the hopper 14 below correspondence.
Native system adds pretreatment shunting heat abstractor, this device is arranged between smelting furnace and pulsed jet cloth filter 20, during use, the tail gas that smelting furnace produces flows in casing 11 from air inlet pipe 12, owing to being arranged side by side multicomponent flow heat dissipation pipeline on casing 11, therefore gas starts shunting after entering casing 11, due to U-tube 13 respectively with two adjacent chamber, therefore gas is when flowing, gas flows into U-tube 13 from casing, flow into from one end of U-tube 13, flow out from the other end of U-tube 13 again, again flow back in casing 11, subsequently into next U-tube 13, the like, until gas exits into pulsed jet cloth filter from casing 11.In shunting radiation processes, the temperature of gas reduces, and the gas temperature entering pulsed jet cloth filter is not above the highest bearing temperature of dust-removal cloth-bag material, the good dedusting effect of dust-removal cloth-bag；Meanwhile, gas is during cooling, and steam condenses in U-tube, when gas after treatment enters in pulsed jet cloth filter, it is not easy to the phenomenon of condensation occur, is the most just not easy the situation occurring sticking with paste bag, it is ensured that the dust removing effects of pulsed jet cloth filter.
The U-tube 13 of native system can, the tubing of good heat dissipation effect low with alternative costs, such as aluminium alloy etc., be so favorably improved the shunting radiating effect to boiler exhaust gas.
Due to dust-removal cloth-bag, after sticking with paste bag, hole can be blocked, after dust-removal cloth-bag blocking, gas flowing is slowly, vent gas treatment efficiency is low, for this, native system also includes that air-introduced machine 30, air-introduced machine 30 are arranged between pulsed jet cloth filter 20 and tail gas absorber 40, for being drawn in tail gas absorber by the tail gas after pulsed jet cloth filter 20 dedusting.
In the present embodiment, the bottom of hopper 14 is provided with electromagnetic valve, and electromagnetic valve is for controlling opening or closing of feed hopper bottom discharging opening.Electromagnetic valve is in normally off, when needing to reclaim the dust in hopper 14, PLC can be used to automatically open up electromagnetic valve, when electromagnetic valve is opened, the dust in hopper 14 is discharged, the dust accumulation of recovery can be got up after discharge, for secondary smelting, to reach metalliferous mineral is made full use of.
Finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent, without deviating from objective and the scope of technical solutions of the utility model, it all should be contained in the middle of right of the present utility model.
