Description

A kind of pressure vessel base blowdown device
Technical field
The utility model is related to a kind of blowdown apparatus more particularly to a kind of pressure vessel base blowdown devices.
Background technology
The blowdown used in thermal power plant's pressure vessel at present is generally to use manually operated door, periodically using manual control switch's manually operated door come The sewage in container is excluded, often occurring artificial forgetting blowdown or valve rust in use extremely leads to blowdown not in time, So that field device is frequently intake, oil inlet, causes equipment malfunction or tripping, the reliability and stability of equipment to reduce, serious shadow Ring Power Plant safe operation.Patent 201520966581.4 discloses a kind of pressure vessel base blowdown with automatic blowdown function Device, but the device is controlled by program, and pneumatic operated valve is opened after reaching setting time and realizes blowdown, there are blowdown excessively frequencies Numerous or blowdown not in time the problem of, the device also needs to external startup air source in addition, and blow-off pipe and escape pipe use different pipes Road is arranged, and entire drainage is more complicated.
Utility model content
The technical problem to be solved by the utility model is to provide one kind can be according to real-time humidity inside pressure vessel Automatic pollution discharge and the pressure vessel base blowdown device for having both gas conveying function.
In order to solve the above technical problems, the pressure vessel base blowdown device of the utility model, including connect with pressure vessel bottom The first conveyance conduit connect, the first conveyance conduit other end are connected to the entrance of two-position three way magnetic valve, described two three Two outlets of three-way electromagnetic valve are connected to blow-off pipe and the second delivery pipe respectively, and second delivery pipe delivers the gas to outside Equipment further includes being mounted on the hygronom that positon of near bottom is leaned on inside pressure vessel, and the two-position three way magnetic valve and hygronom are equal It is electrically connected with programmable controller.
Further, the blow-off pipe is docked with blowdown collection device.
Further, first delivery pipe is equipped with condenser.
Further, it is equipped with manually-operated gate in first conveyance conduit and the second delivery pipe.
Further, automatic valve and baroceptor, the control of the automatic valve are additionally provided in second delivery pipe End is electrically connected with the baroceptor, and the control terminal uses constant pressure air feeding according to the supply gas pressure that baroceptor monitors Mode automatically adjust the aperture of the automatic valve, to ensure that pipe network supply gas pressure is stablized, eliminate network security hidden danger.
Utility model works process is:Humidity inside hygronom monitoring pressure in real time container, inside pressure vessel After the value for reaching setting, hygronom send moisture signal to programmable controller, and after programmable controller calculation process, Solenoid valve is sent a command to, is connected to blow-off pipe after electromagnetism valve events, carrying out automatic pollution discharge can compile after reaching setting time Range controller control electromagnetism valve events are connected to realization gas supply with the second delivery pipe, to complete an automatic pollution discharge process.
The utility model is not only simple in structure, and according to pressure vessel interior humidity automatic pollution discharge and can have both gas Conveying function.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of pressure vessel base blowdown device includes the first conveyance conduit 2 being connect with 1 bottom of pressure vessel, First conveyance conduit, 2 other end is connected to the entrance of two-position three way magnetic valve 3, two outlet difference of two-position three way magnetic valve 3 It is connected to blow-off pipe 4 and the second delivery pipe 5, the second delivery pipe 5 delivers the gas to external equipment 6, further includes being mounted on pressure The hygronom 7 of positon of near bottom is leaned in 1 inside of container, and two-position three way magnetic valve 3 and hygronom 7 are electrically connected with programmable controller 9. Blow-off pipe 4 is docked with blowdown collection device 10.It is equipped with manually-operated gate 11 in first conveyance conduit 2 and the second delivery pipe 5.
Utility model works principle is:Humidity inside 7 monitoring pressure in real time container 1 of hygronom, when in pressure vessel 1 After the humidity in portion reaches the value of setting, hygronom 7 send moisture signal to programmable controller 9, and passes through programmable controller 9 After calculation process, two-position three way magnetic valve 3 is sent a command to, two-position three way magnetic valve 3 is connected to after acting with blow-off pipe 4, is carried out Automatic pollution discharge, after reaching setting time, programmable controller 9 controls the action of two-position three way magnetic valve 3 and connects with the second delivery pipe 5 It is logical to realize gas supply, to complete an automatic pollution discharge process.
In the present embodiment, the sewage that blow-off pipe 4 is discharged is collected in time by blowdown collection device 10, realizes zero-emission It puts, by the way that on the first conveyance conduit 2 and the second delivery pipe 5, equipped with manually-operated gate 11, blowdown and gas supply can also be manually controlled, It is also convenient for overhauling.Water content during setting condenser 8 can also further decrease gas on the first conveyance conduit 2, to protect Demonstrate,prove the safety of external equipment 6.
The specific embodiments of the present invention are described in detail above, but the utility model be not limited to it is above-mentioned Embodiment can also not depart from the utility model aims within the knowledge of a person skilled in the art Under the premise of various changes can be made.
