Can technical field.
Background technology
Traditional handicraft wood fibre is direct from cyclone separator top discharge cylinder by the tail gas after cyclone separator separation
Idle discharge is put, the exhaust temperature for going out cyclone separator discharge drum is about 65 DEG C or so, at present, because wood industry dries air quantity and fibre
The characteristics of tieing up thin, by containing substantial amounts of wood-fibred in the gas discharged after first separation, the few fibers are discharged into air
Seriously exceed national requirements for environmental protection discharge standard, serious dust pollution is caused to air, while being made to the production cost of enterprise
Into very big waste.Air-introduced machine in traditional handicraft draws extraneous cold wind, and the temperature that wood industry dry fiber needs is 120
DEG C, it is therefore desirable to cold wind is heated by the steam in radiator, gasinlet temperature is according to the different regions four seasons temperature difference
Change is very big, and particularly northern area winter steam consumption increases, and directly increases production cost, to constrain product market competing
Strive power.
And also have some drying system dust arresters, such as China Patent No. 201510007383.X at present, it is entitled " artificial
Plate drying system dust arrester ", by setting redrying cyclone separator, by primary drying cyclone separator exhaust ports
Dusty gas carries out secondary cyclone dedusting (also can three cyclone dust removal), reduces the concentration of emission of pollutant in discharge gas,
Although reclaiming a large amount of fiber (wood powder) raw materials by multiple dedusting, recycled, increase secondary or even repeatedly remove
Dirt, efficiency can be reduced step by step, and increase equipment is more, and investment cost is high；The hot blast of whirlwind higher temperature out cannot
Reclaim, cause the waste of the energy.
Utility model content
The purpose of this utility model is to provide a kind of device of wood-based plate drying system environmental protection and energy saving, cyclone entrance
Set a process pipelines guide to drying air fan entrance, drying air fan porch set air door, adjust entrance air quantity, by with
The cooperation adjustment of former air door, it is to avoid dust flare, reduces pollution of the dust to air, and the technique after adjustment is reclaimed and dries tail
Gas, makes long-term drying air fan inlet temperature stabilization at 50 DEG C or so, has saved substantial amounts of steam（Winter saves particularly evident）, together
When emission in carry secretly wood-fibred be recycled, reduce production cost, solve background technology exist above mentioned problem.
The technical solution of the utility model is：
A kind of device of wood-based plate drying system environmental protection and energy saving, comprising cyclone separator, exhaust port, drying duct,
Drying air fan inlet tube, drying air fan air door, drying air fan, heater, fiber feed bin and process pipe；Drying air fan entrance
Pipe be connected with drying air fan by after drying air fan air door, the outlet of drying air fan by connecting drying duct after heater,
The outlet connection cyclone separator of drying duct, is provided with fiber feed bin below cyclone separator, set at the top of cyclone separator
There is exhaust port, exhaust port connects drying air fan inlet tube by process pipe.
The process pipe is provided with damper, and process pipe is connected between drying air fan air door and drying air fan
On drying air fan inlet tube.
Cold wind enters drying air fan inlet tube, first mixes with the tail gas reclaimed through process pipe, is then sent through drying air fan
Enter in heater and continue to be heated to 120 DEG C of required temperature using steam, subsequently into dry fiber material in drying duct,
Fibre material after drying is separated through cyclone separator, and the dry material for separating enters fiber feed bin is used for rear operation pressure
Plate, steam and hot blast after cyclone separator dry fiber material, temperature enters work at 65 DEG C -70 DEG C by exhaust port
Skill pipeline, drying air fan inlet tube is entered by process pipe, is mixed with the cold wind for entering drying air fan inlet tube, the amount of cold wind
Adjusted by drying air fan air door, the air quantity of steam and hot blast after cyclone separator dry fiber material, by damper
Regulation, makes mixed hot blast temperature for 50 DEG C -52 DEG C, has so both reclaimed the heat of tail gas, saves used by heater
The amount of steam, has also reclaimed the wood-fibred in tail gas, it is to avoid the pollution of waste and dust flare to air.
The utility model beneficial effect：Cyclone entrance sets a process pipe and guides to drying air fan entrance,
Drying air fan porch sets air door regulation entrance air quantity, adjusted by cooperation with drying air fan air door, it is to avoid outside dust
Float, reduce pollution of the dust to air, the technique after adjustment is reclaimed and dries tail gas, make long-term drying air fan inlet temperature stabilization
At 50 DEG C -52 DEG C, substantial amounts of steam has been saved（Winter saves particularly evident）, while the wood-fibred carried secretly in emission is obtained
Reclaim, while the dust pollution question arranged outside tail gas and brought is solved, with good economic benefit and environmental benefit.
