Description
Technical field
The utility model belongs to field of boilers, is specifically related to a kind of boiler smoke flying dust back-burning device.
Background technology
The flue gas that existing boiler furnace burning produces needs process just can reach discharge standard, and containing a large amount of flying dusts in flue gas, processes more complicated.The flying dust that furnace outlet gets off through cyclone collection by prior art is delivered in stove through batcher and burns, to reduce fly ash combustible material, improves boiler thermal output.But in actual motion; because flying dust temperature is higher; easily there are bite serious problems in batcher; there are some bulky grains a little or ash quantity is more batcher will be caused to block stop operating; motor decelerating mechanism is caused to damage; burn-down of electric motor, has a strong impact on production, and flying dust is to enter in boiler tube road phenomenon of depositing serious.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of boiler smoke flying dust back-burning device, and fly ash combustible material is burnt again, improves boiler thermal output.
Boiler smoke flying dust back-burning device described in the utility model, comprise boiler furnace, boiler furnace side is communicated with cyclone inlet by flying dust flue, cyclone separator one side outlet is communicated with smoke processing system by purifying smoke pipeline, cyclone separator outlet at bottom is communicated with fluidisation air compartment by high temperature flying dust pipeline, fluidisation air compartment side is connected with the first air compressor machine by the first compressed air piping, fluidisation air compartment opposite side is connected with boiler furnace by pipeline, be connected with the second air compressor machine by the second compressed air piping bottom fluidisation air compartment, first compressed air piping is provided with the first valve, second compressed air piping is provided with the second valve, fluidisation air compartment bottom interior wall is provided with mushroom blast cap.
Fluidisation air compartment bottom interior wall is provided with 4-6 mushroom blast cap.
During use, the flue gas that boiler furnace produces enters cyclone separator process through flying dust flue, and the purifying smoke after process enters smoke processing system through purifying smoke pipeline and is further processed.The high temperature flying dust obtained after process enters in fluidisation air compartment through high temperature flying dust pipeline under self gravitation effect, the compressed air sent here from the second air compressor machine enters fluidisation air compartment through the second compressed air piping and blows bottom fluidisation air compartment, utilize blast by high temperature flying dust fluidisation, fluidisation air compartment bottom interior wall is provided with mushroom blast cap, mushroom blast cap makes to form a small-sized fluidized bed bottom fluidisation air compartment, makes flying dust more even.The compressed air sent here from the first air compressor machine enters fluidisation air compartment through the first compressed air piping from fluidisation air compartment side and blows, and utilizes blast to be blown in boiler furnace by high temperature flying dust and burns.First compressed air piping is provided with the first valve, and the second compressed air piping is provided with the second valve, achieves and adjusts flying dust amount by controlling air quantity.
In sum, the utility model has the following advantages:
(1) furnace outlet is delivered in stove through the flying dust that cyclone collection gets off and burns by the utility model after fluidisation air compartment purges, and to reduce fly ash combustible material, improves boiler thermal output.
(2) the utility model flying dust sprays evenly, solves flying dust entering the alluvial phenomenon in boiler tube road.
(3) the utility model is rational in infrastructure, can adjust flying dust amount by controlling air quantity.
