Description
Technical Field
The utility model belongs to the technical field of exhaust-gas treatment equipment and specifically relates to a biomass boiler's exhaust treatment device.
Background
With the elimination of coal-fired boilers, the use of biomass boilers is increasing day by day, but the problems that accompany the biomass boilers are not few. When the waste gas of a small biomass boiler is treated, the traditional process of combining water curtain dust removal and bag dust collection is not perfect, the treatment effect is not ideal, and the small blocks and carbides which are not fully combusted are entrained in smoke dust and enter a bag dust remover to be adsorbed on a bag to generate secondary combustion. This is one of the common incidents in this system.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a biomass boiler's exhaust treatment device in order to solve the not enough of above-mentioned technique, it can effectively filter the smoke and dust, and uses safe and reliable.
In order to achieve the purpose, the utility model discloses a biomass boiler's exhaust treatment device, including biomass boiler, cooler, cyclone, spark arrester, sack dust collector, draught fan and chimney, biomass boiler's exhaust port connects gradually cooler, cyclone, spark arrester, sack dust collector, draught fan and chimney through the pipeline, the spark arrester includes an inclosed box, and the interval is provided with 2-3 layers of back-fire relief filter screen side by side in the box, and the back-fire relief filter screen separates the box for a plurality of cavitys that set up side by side, and wherein the cavity in the one end outside is connected with cyclone, and the cavity in the other end outside is connected with sack dust collector.
The cooler is an air-cooled heat exchanger or a water-cooled heat exchanger.
According to the technical scheme, the temperature of the flue gas and the waste gas generated by the biomass boiler is high, the flue gas is cooled by the cooler firstly, the air-cooled heat exchanger or the water-cooled heat exchanger can be selected according to actual requirements, heat in the flue gas is converted and utilized, and the cooler does not contact water and other media with the flue gas in the flue gas cooling process, so that the humidity of the flue gas cannot be increased, so that particles in the flue gas are not easy to adhere to other dust removing equipment in the subsequent treatment process of the flue gas, the maintenance investment is reduced, and the biomass boiler is safe and reliable; the cooled flue gas enters a cyclone dust collector, and most of dust in the flue gas, including small blocky particles and carbides which are not fully combusted, can be removed; then the flue gas gets into the spark arrester, and the flue gas need pass through multilayer back-fire relief filter screen when passing from the inside spark arrester, and the back-fire relief filter screen can further purify the flue gas, especially catches remaining not fully burnt tiny massive particle and carbide to ensure the security of rear equipment operation. Meanwhile, residual fine blocky particles and carbides in the smoke entering the flame arrester are less, so that the filter screen is not easily blocked, and the use stability is high. The flue gas after cyclone and spark arrester filtration gets into the bag dust collector, and the smoke and dust in this place flue gas is less relatively, collects the back with the smoke and dust through the bag dust collector, carries to the chimney under the effect of draught fan and carries out discharge to reach standard. The filter bag of the cloth bag dust collector adopts a polyphenylene sulfide filter material, and is required to be subjected to waterproof, oil-proof and flame-retardant treatment, so that the safety in the using process is further improved.
The utility model provides a biomass boiler's exhaust treatment device, it is through reasonable structural design, can carry out the smoke and dust after fully cooling down and filtering to the flue gas that biomass boiler produced, waste gas etc. and collect emission again, its processing procedure safe and reliable.

Detailed Description
The invention is further described by the following embodiments in conjunction with the accompanying drawings.
Example 1:
as shown in fig. 1, the exhaust treatment device of biomass boiler of this embodiment description, including biomass boiler 1, cooler 2, cyclone 3, spark arrester 4, sack dust collector 5, draught fan 6 and chimney 7, biomass boiler 1's exhaust port connects gradually cooler 2, cyclone 3, spark arrester 4, sack dust collector 5, draught fan 6 and chimney 7 through the pipeline, flame arrester 4 includes an inclosed box, and the interval is provided with 2 layers of back-fire relief filter screens side by side in the box, and back-fire relief filter screen separates the box for a plurality of cavitys that set up side by side, and wherein the cavity in the one end outside is connected with cyclone 3, and the cavity in the other end outside is connected with sack dust collector 5. The cooler 2 is a water-cooling heat exchanger.
Example 2:
the present embodiment describes an exhaust gas treatment device of a biomass boiler, which is different from embodiment 1 in that: the number of layers of the fire retardant filter screen is 3, and the cooler 2 is an air-cooled heat exchanger.
