Abstract
A kind of rotary kiln exhaust gas treating apparatus, it is connected between the exhanst gas outlet of rotary kiln (1) and chimney (8), it is made up of gather dust pipe heat exchanger (2), water jacket cooler (6), electric pulse sack cleaner (7) and air exhauster (9) of the gravity be connected in series successively, wherein the gravity entrance of pipe heat exchanger that gathers dust is connected with the exhanst gas outlet of rotary kiln, and the outlet of air exhauster is connected with chimney.The utility model can reclaim the micro mist in rotary kiln exhaust gas, can effectively prevent micro mist to be discharged in air.
Description
Technical field
The utility model relates to Environmental-protecting dust-removing equipment technical field, particularly relates to a kind of device being applied to rotary kiln exhaust gas process.
Background technology
Produce in reduction titanium process at rotary kiln, the tail gas that rotary kiln is discharged often accompanies a small amount of powder (breeze of micro mist shape and the coal dust of micro mist shape), gravity is adopted to add water film dedusting, be merely able to remove any dust of a bit large and Heavy Weight of granularity, still some micro mists are had along with smoke stack emission is in air, if adopt electric pulse sack cleaner, the micro mist in tail gas can be reclaimed, and effectively prevent micro mist to be discharged in air.It is a kind of rotary kiln exhaust gas treating apparatus of more environmental protection.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly micro mist in rotary kiln exhaust gas is reclaimed, can effectively prevent micro mist to be discharged into rotary kiln exhaust gas treating apparatus in air.
A kind of rotary kiln exhaust gas treating apparatus that the utility model provides, it is connected between the exhanst gas outlet of rotary kiln and chimney, it is made up of gather dust pipe heat exchanger, water jacket cooler, electric pulse sack cleaner and air exhauster of the gravity be connected in series successively, wherein the gravity entrance of pipe heat exchanger that gathers dust is connected with the exhanst gas outlet of rotary kiln, and the outlet of air exhauster is connected with chimney.
In above-mentioned, the gather dust cold air inlet of pipe heat exchanger of gravity connects air blast, and hot-blast outlet is emptying.
The utility model has the following advantages:
1, heat recovery, the waste heat of recovery can carry out the oven dry of wet ore deposit.
2, small investment, cost is low.
3, simple to operate, good purification, meets environmental requirement.
4, device is simple, is convenient to install.
5, the hot water that water jacket cooler exchanges can be used for workman and has a bath, and saves the energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to Fig. 1, a kind of rotary kiln exhaust gas treating apparatus that the utility model provides, it is connected between the exhanst gas outlet of rotary kiln 1 and chimney 8, be made up of gather dust pipe heat exchanger 2, water jacket cooler 6, electric pulse sack cleaner 7 and air exhauster 9 of the gravity be connected in series successively, wherein the gather dust entrance of pipe heat exchanger 2 of gravity is connected with the exhanst gas outlet of rotary kiln 1, the outlet of air exhauster 9 is connected with chimney 8, and the gather dust cold air inlet 4 of pipe heat exchanger 2 of gravity connects air blast 5, and hot-blast outlet 3 is emptying.
During use, the hot exhaust gas that rotary kiln is about 700 DEG C is first under the suction of air exhauster 9, to be gathered dust pipe heat exchanger 2 by gravity, reclaim most granularity large a bit and any dust of Heavy Weight, simultaneously air blast 5 toward gravity gather dust pipe heat exchanger 2 heat exchanger tube in blow a cold wind over and carry out tail gas heat exchange cooling, heat exchange hot blast is out used for carrying out the oven dry of wet ore deposit, carry out heat recovery, at this moment exhaust temperature have decreased to about 300-350 DEG C, further tail gas is cooled to about 150 DEG C by water jacket cooler 6 again, tail gas finally enters the recovery dedusting that electric pulse sack cleaner 7 carries out micro mist, at this moment the tail gas be discharged in air will be very clean, very environmental protection.
Claims (2)
