Description
Technical field
This utility model is a kind of damper system, particularly to a kind of airtight baffle ventilation door system of scalable, for the pipeline that equipment blocking and dust content are high.
Background technology
Developing rapidly and the improving constantly of living standards of the people along with socioeconomic, problem of environmental pollution is increasingly subject to concern and the attention of country.The smoke contamination emission numerical value that wherein coal-burning power plant produces is surprising, and PM2.5 is the principal element affecting urban air quality and visibility, and the serious harm people's is healthy.Play " the big pollutant emission standard of thermal power plant " of execution on January 1st, 2012, it is desirable to coal-burning power plant reaches≤30mg/m3, in addition requirement≤the 20mg/m3 such as some developed provinces and cities such as Beijing, Shanghai, Guangdong.So, coal-burning power plant must take efficient, stable dedusting technology, effectively to control the soot emissions of trace.
Summary of the invention: the 1980s rises, electric cleaner becomes the first-selection of China's coal-burning power plant's cleaner, and its principle is to utilize dust charged in the electric field and deposit to electrodes for removing dust under electric field force effect.Electric cleaner has that running resistance is low, system pressure loss is little；Equipment can bear high temperature impact；Core component is steel construction, long service life；The advantages such as operation maintenance workload is little.But electric cleaner is designed by certain coal, due to the impact of a variety of causes, in boiler running process, the coal-fired condition of use can vary widely.Therefore, cause the efficiency of dust collection of electric cleaner it may happen that very big fluctuation, affect dust removing effects.Its installation cost and power consumption also sharply increase therewith, make electric cleaner be faced with the contradiction that flue gas condition is more and more uncertain and emission request is increasingly higher.
In the process of dedusting, often using pipeline, or carry out airtight to pipeline, existing product, operating characteristics is relatively low, and sealing is undesirable simultaneously.
Chinese patent 00252736.7, open a kind of Double row blocking plate type wind gate, included seal fan, pipeline, stop valve, adjustment valve and pressure-measuring pipe etc. by air door body and enclosed air system to form, it is characterized in that air door body by forward and backward with couple the rectangle frame support body doorframe of flange is arranged at least double, often drain into few a pile baffle plate assembly and form.This structure cannot meet existing demand.
Summary of the invention
This utility model mainly solves the deficiencies in the prior art, compact conformation, has good control characteristic, adopts the airtight baffle ventilation door system of scalable of the worm gearing of manual rocker or motor-driven.
Above-mentioned technical problem of the present utility model is addressed mainly by following technical proposals:
A kind of airtight baffle ventilation door system of scalable, including framework, described framework is provided with rotating shaft, it is cased with carrying out with rotating shaft the baffle plate of displacement outside described rotating shaft, the top and bottom of described baffle plate are matched with frame inner wall respectively, described baffle plate is overturn by transmission component, and the described inwall of framework upper end, the inwall of lower end are respectively equipped with sealed paper strip seal, and described baffle plate and sealed paper strip seal are movable sealing.
As preferably, described transmission component includes swing arm and reductor, and described swing arm and rotating shaft are fixedly connected, by worm and gear phase transmission between described swing arm with reductor.
As preferably, the two side ends of described baffle plate is respectively equipped with beveled end, and described beveled end is mutually airtight with sealed paper strip seal.
Operational torque is not more than to the isolation air door of 300Nm, adopts wind actuating device；Need more than 300Nm adopt motor add Worm Wheel System case (speed ratio i=20 25 30 40 50 60 etc.), the anglec of rotation less than 90 ° of general total travel times less than 45 seconds.The safety allowance of operation device moment is 1.3.
The air leak rate of air curtain of this baffle-type air door controls, about 1.5%, to be generally adopted rectangle steel door.For ensureing air leak rate of air curtain, contact employing between baffle plate with doorframe and inlay silicone rubber；And wrapped in teflon pad.Both avoided firmly contacting between the two, and saved the blower fan sealed, not only ensure that sealing ensured again corrosion-resistant, wear-resistant.Baffle plate adopts 316l two panel construction, and both proof strength in turn ensure that abrasion-proof corrosion-proof performance, can use for a long time in flue.For pioneering in baffle door industry, this patent goes out to be suitable for, through examination with great concentration, system and practice just Successful tests for many years, the baffle plate damper that various flue (suitable in the flue of multiple exhaust gas volumn and smoke content) uses, and can be certainly also used to switching mode baffle door.
Technical characterstic:
1, air leak rate of air curtain controls about 1.5%, and general domestic baffle door air leak rate of air curtain is 2%.
2, baffle door adopts soft contact with door frame contact, not only ensures slip but also can abrasion-proof corrosion-proof.
3, adopt worm gearing, there is self-locking performance, arbitrarily can regulate as damper and can self-locking；
4, this type baffle door, small investment, cheap, be several times lower than than the actuator of import.Again can life-time service, there is abrasion-proof corrosion-proof characteristic.
5, baffle plate adopts 316L material, it is ensured that the life-time service of baffle door, not only wear-resisting but also corrosion resistant；
6, actuating device and motor are outside flue, it is simple to keep in repair and avoid, for a long time by flue gas corrosion, can using for a long time；
7, baffle door arranges two ends limit switch, prevents driving device continuation action during to indicate standard-sized sheet or be fully closed.
Therefore, the airtight baffle ventilation door system of scalable that this utility model provides, compact conformation, obvious energy conservation, operating cost is low.
