The utility model is characterized in that a sealed channel is arranged between the periphery of the edges of the door panel and the doorframe and is connected with a sealing air tube which is arranged outside the casing, and the tube is connected with a sealing fan. The accessory can effectively prevent end gas from leaking, and has a good sealing function.
Description
The utility model belongs to a kind of annex that is used for the combustion gas unit.Specifically a kind of baffle door.
Along with the enforcement of China's West-East National Gas Transmission Project, the utilization rate of combustion gas unit can be more and more higher.
When using the combustion gas unit, its discharge tail gas temperature all directly was discharged in the air up to 600～700 ℃ in the past, did not only meet environmental requirement, and caused a large amount of losses of heat energy.
Combustion gas unit combined cycle system is a kind of comparatively popular in the world recirculating system of utilizing fuel gas generation at present, in this system, tail gas is fed waste heat boiler, and the steam that utilizes boiler to produce provides the energy generating.
Usually, when waste heat boiler was worked, the tail gas of combustion gas unit just entered waste heat boiler, and when waste heat boiler was stopped transport or overhaul, tail gas was just discharged by chimney.Need a door that plays the threeway effect at this, change the flow direction of tail gas by its work, and this must have certain sealing and flexibility.
The purpose of this utility model is to design a kind of combustion gas unit combined cycle by-pass damper door, so that make full use of the waste heat of combustion gas unit, and, have better seal, operate also more convenient.
Its main technical schemes comprises box-shaped shell and is installed on outer driving mechanism of box-shaped shell and the door-plate that is installed in the box-shaped shell, import and outlet one are arranged on box-shaped shell and export two, and in outlet one and outlet two, doorframe is set respectively, it is characterized in that around the edge of door-plate and between doorframe seal channel being arranged, the sealing passage sealing air pipeline outer with being installed on housing is connected, and pipeline is connected with seal fan.
In the edge of door-plate the butterfly diaphragm seal is set, seal channel is formed in the space that butterfly diaphragm seal and doorframe surround.
In driving mechanism, transmission mechanism is installed on the top of box-shaped shell, and fixedly connected crank on the transmission main shaft of transmission mechanism is in the other end articulated linkage of crank, the other end and the door-plate of connecting rod are hinged, and door-plate utilizes rotary main shaft to be hinged on the box-shaped shell corresponding to two doorframe joint portions.
Box-shaped shell is made up of housing and heat-insulation layer; Outlet one is positioned at the top of box-shaped shell, and import is positioned on the same axis with outlet two; On box-shaped shell, explosion proof door is set, sealing air heater and sealing air valve are set on the sealing air pipeline corresponding to outlet two positions.
Because exhaust temperature is high, so require this to have 100% sealing property, allow anything but to leak, requirement equipment is reasonable, the maloperation state of stopping that two outlets are closed simultaneously or opening simultaneously, it is zero that the effluent amount that requires simultaneously to accomplish in the tail gas handoff procedure gradually reduces, and the opposite side flow progressively increases up to 100%, in order to avoid because of accidents such as the high-temperature tail gas obstruction set off an explosion.
In this device, door-plate is installed on the joint portion of two outlets, when door-plate turns to another when outlet from an outlet, the variation of its flow can be satisfied above-mentioned requirements fully, and has self-locking action, promptly when closing an outlet, must open another outlet, thoroughly avoid two possibilities that outlet is opened simultaneously or closed simultaneously; Secondly, used toggle reliable in action, sensitivity are convenient to operation; In addition, the butterfly diaphragm seal is set around door-plate, when door-plate cooperates with doorframe, have certain flexible butterfly diaphragm seal and be close on the doorframe, produce certain pretightning force, between butterfly diaphragm seal and doorframe, form seal channel, the high pressure draught that is higher than tail gas pressure that utilizes blower fan to produce again pours in the seal channel, between door-plate and doorframe, form the high pressure draught passage, thereby thoroughly block the leakage of tail gas between door-plate and doorframe, play good sealing effectiveness.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the A-A view of Fig. 2.
Fig. 4 is the enlarged drawing of B among Fig. 3.
As shown in the figure:
This device comprises box-shaped shell 19 and is installed on box-shaped shell 19 driving mechanism outward and the door-plate 15 that is installed in the box-shaped shell 19, import 5 and outlet 1 are arranged on box-shaped shell 19 and export 2 11, and in outlet 1 and outlet 2 11, doorframe 17 and 17 ｀ are set respectively, around the edge of door- plate 15 and 17 on doorframe seal channel 16 is arranged, the sealing passage 16 sealing air pipeline 4 outer with being installed on housing 19 is connected, and pipeline 4 is connected with seal fan 2.In the edge of door-plate 15 butterfly diaphragm seal 22 is set, seal channel 16 is formed in the space that butterfly diaphragm seal 22 and doorframe 17 surround.Seal channel also can utilize other forms of structure to realize.As labyrinth type, semicircle or oval or the like.
In driving mechanism, transmission mechanism 8 is installed on the top of box-shaped shell 19, fixedly connected crank 7 on the transmission main shaft 18 of transmission mechanism 8, other end articulated linkage 20 at crank 7, the other end of connecting rod 20 and door-plate 15 are hinged, and door-plate 15 utilizes rotary main shaft 9 to be hinged on the box-shaped shell 19 corresponding to doorframe 17 and 17 ｀ joint portions.Box-shaped shell 19 is made up of housing 13 and heat-insulation layer 12, in order to avoid tail gas heat quantity is lost, housing has certain intensity again.Export one 6 tops that are positioned at box-shaped shell 19, import 5 is positioned on the same axis with outlet 2 11, import is used for entering of tail gas, outlet two is connected with waste heat boiler, outlet one is connected with chimney, and this mode helps the utilization of tail gas, can allow tail gas under the situation that is not having turning, directly enter waste heat boiler, reduce the loss.On the box-shaped shell 19 corresponding to outlet 2 11 positions explosion proof door 10 is set, when the tail gas hypertonia, this explosion proof door can be opened automatically, discharges unnecessary tail gas, in order to avoid cause an explosion accident.
