Description
Technical field
The present invention relates to boiler manfacturing field, particularly relate to a kind of filtration for condensing boiler and flue gas check device.
Background technology
Condensing boiler is exactly sensible heat in utilize efficient waste heat of condensation retracting device high-temperature flue gas that absorption boiler discharges and the latent heat that discharges of water recovery, to reach the object improving boiler thermal output.Due to the heat that condensing boiler can utilize high-temperature flue gas to take away, so the thermal efficiency is just likely more than 100%, the theoretical maximum thermal efficiency of current condenser boiler can up to 111%.In addition, condensing boiler can also reduce the CO produced because of fuel combustion in flue gas easily
2, NO
xwith a small amount of SO
2growing amount, can aggravate in these mass emissions to air greenhouse effects and produce acid rain.Therefore, condensing boiler is adopted also to have great importance to protection of the environment.
A main hazard relevant to condensing boiler air inlet refers to entrained solid particulate matter in air inlet, the flying dust such as, existed in air, thin smoke-type particle and dissimilar cigarette, dust etc.Their quality are slight, not easily pass through gravity to separate from air-flow, and the hole of the burner of condensing boiler is less, these solid particulate matters can cause burner to block, also likely adsorbed by the lubricating oil between mechanical part, cause boiler normally to work.At present, power plant utilizes different woven filter materials to remove particulate usually from air, and gas flows into and passes fabric, and solid particulate matter is stayed in fabric.Filter needs the long period to be exposed in environment that is hot, abrasiveness and chemical corrosivity, therefore the material for the manufacture of them must can withstand this environment, and especially they should have enough strong ability and bear the pressure of burnt fuel and erosive parti and temperature transient and thermal shock.
Condensing boiler adopts modularized design, is convenient to according to load step-less adjustment.But when wherein part of module quits work, the flue gas of working boiler can flow to boiler room from the air inlet of the boiler stopped, and needs to install flue gas check-valves.
But present widely used filter mainly use one deck screen pack realize interception particle function, its screen pack material is single, shape is single, make effective filtration area little and filter Netease blocking; And screen pack unpicks and washes the high cost that inconvenience can bring follow-up maintenance and cleaning.And the flue gas check device additionally installed occupies certain space, consume extra cost, also affect attractive in appearance to a certain extent.In prior art, multiple stage boiler cannot realize common flue, has certain restriction for practical application in industry.
Summary of the invention
The object of the invention is for overcoming the deficiencies in the prior art, there is provided a kind of can filter out whole particle diameter be greater than the dust of burner pore diameter and stop the flue gas of working boiler to flow to filtration and the flue gas check device of boiler furnace from air inlet simultaneously in condensing boiler burner, solve burner in prior art because of blocking cannot normally work, filter screen dismounting cleaning inconvenient and and the extra check device installed occupy the problem that excessive space brings.
