Description
Technical field
The present invention relates to a kind of device for thermal power station's desulphurization system, be specifically related to a kind of being arranged at thermal power station's coal pulverizer inlet for stopping that hot blast enters the baffle door of coal pulverizer.
Background technology
Along with the fast development of fired power generating unit, medium-speed pulverizer has replaced low speed coal mill becomes the main powder manufacturing apparatus of large-size thermal power plant.Medium-speed pulverizer has an advantage such as reduced investment, low, the easy operation of power consumption as rough type equipment, but there is also that main mill part is easy to wear, equipment overhaul cycle is short, repair time length, can not be synchronization with boiler maintenance etc. shortcoming.Owing to coal pulverizer powder process ability direct relation exerting oneself of generating set, therefore power station ensures the reliability and security of unit operation by the Redundancy Design of medium-speed pulverizer.
Baffle door, as the main xegregating unit of coal pulverizer Yu steam generator system, seems extremely important in systems.Completely cut off door must reliably open when coal pulverizer puts into effect, the necessary security isolation of isolation door when coal pulverizer is in standby or maintenance, and the open and close to isolation door have regular hour requirement.Operating temperature high (about 350 DEG C) residing for isolation door, duct cross-section is big, stress is big, the tightness, the reliability requirement that simultaneously close off are high, the isolation door that the most domestic power station uses all is not up to preferable condition of work, and this is all a potential safety hazard the biggest to operation, the maintenance of power station coal pulverizer.
Current baffle door mostly is mechanical type, and sealing effectiveness is poor, and desulfuration efficiency is low, and seal changes difficulty, maintenance inconvenience, it is impossible to meet the demand of power industry.
Summary of the invention
The purpose of the present invention is overcoming above-mentioned weak point, it is provided that a kind of high resiliency double seal baffle plate door.
The technical solution adopted in the present invention is as follows: high resiliency double seal baffle plate door is made up of doorframe and revolving door.Described doorframe is provided with fire resistant anticorrosive bearing block, shaft sealer, inflation electromagnetic valve switch, revolving door limit switch and door sealing assembly, on described revolving door, supporting spindle is set, it is provided with handle on described supporting spindle, described crank is connected with drive link, described drive link is connected with adjacent revolving door crank, each revolving door is made to form shutter form, can synchronize to open, close synchronously, described revolving door surrounding dress seal, elastic inflated capsule is set in described door sealing assembly, inflation inlet and air bleed outlets is set on described elastic qi of chong channel ascending adversely capsule, equipped with air pressure regulator and Pressure gauge on described inflation inlet, equipped with inflation magnetic valve and small-sized air compressor group in described inflation outlet, equipped with disappointing magnetic valve on described air bleed outlets.
Described door sealing assembly uses high resiliency, heat-resisting, high-abrasive material composition, is made up of seal, air bag.
Described doorframe and revolving door contact surface form male and fomale(M&F) formula and firmly seal shape.
Qi of chong channel ascending adversely capsule described in prioritization scheme is that pressure high-temp resistant highly elastic material is made further.
Prioritization scheme fire resistant anticorrosive bearing block is made up of graphite material further.
Beneficial effects of the present invention: compared with prior art, high resiliency double seal baffle plate door of the present invention forms dual layer sealing effect, ground floor seals: doorframe and revolving door contact surface form the hard sealing effectiveness of male and fomale(M&F) formula, the second layer seals: qi of chong channel ascending adversely capsule forms different shapes according to the gap between doorframe and revolving door contact surface after inflation, reaches to completely attach to the effect sealed.Implemented by above, solve baffle door local deformation well, dust stratification causes to close the door in imprecision leakage and with the phenomenon that leaks outside, eliminate potential safety hazard.There is the advantage such as simple in construction, easy to operate, safe and reliable, intelligence degree is high, installation is easy, maintenance is convenient, length in service life.The most also there is the features such as reliability is high, security is good, practical, it is possible to produce good economic benefit and social benefit.

Detailed description of the invention
As it is shown in figure 1, the present invention is made up of doorframe (1) and revolving door (11).Doorframe (1) arranges graphite shaft bearing (3), shaft sealer (2), electromagnetic valve switch (5), revolving door limit switch (4), electric operator (9) and door sealing assembly (13) constitute.Revolving door (11) is provided with supporting spindle (6), and supporting spindle (6) is provided with crank (7), and crank (7) is connected with drive link (8), drive link (8) is connected with adjacent revolving door crank, guarantee that each revolving door forms shutter form, can synchronize to open, close synchronously.Additionally the surrounding of revolving door (11) is equipped with door sealing assembly.Inflation inlet (10) and air bleed outlets (12) is had, equipped with inflation magnetic valve and small-sized air compressor group on inflation inlet (10), equipped with disappointing magnetic valve on air bleed outlets (12) on door sealing assembly.Door sealing assembly is made up of seal, qi of chong channel ascending adversely capsule.
High resiliency double seal baffle plate door running status of the present invention is:
When revolving door (11) is opened, electric operator (9) brings into operation, and electric electromagnetic threshold switch (5) first works, and opens disappointing magnetic valve, and the air bag of door sealing assembly (13) starts to lose heart, and air pressure declines, air bag shrinks, depressurization；When electric electromagnetic threshold switch (5) quits work, crank (7) opens the revolving door (11) being connected with drive link (8), revolving door limit switch (4) the beginning action when revolving door (11) runs 90 ° simultaneously, executing agency (9) is out of service, and revolving door (11) stops operating.
When revolving door (11) is closed, electric operator (9) starts inverted running, crank (7) closes, with drive link (8), the revolving door (11) being connected, revolving door limit switch (4) the beginning action when revolving door (11) inverted running 90 °, executing agency (9) is out of service, and revolving door (11) stops operating.Electric electromagnetic threshold switch (5) work simultaneously, open inflation magnetic valve, the air bag of door sealing assembly (13) starts inflation, air pressure rises, and air bag expands, and starts to seal, when the air gauge inflating magnetic valve connection reaches certain numerical value, inflation magnetic valve quits work, and inflation terminates, and reaches firmly to seal the double sealing effect with air sac sealing.
The above is only in order to illustrate technical scheme and unrestricted, other amendment or equivalent that technical scheme is made by those of ordinary skill in the art, without departing from the spirit and scope of technical solution of the present invention, all should contain in the middle of scope of the presently claimed invention.
