Abstract
The utility model provides a boiler blow -off flash chamber which even arranges and installs on same chassis with deciding to arrange, even the sewer exports through parallelly connected each other flow control pipeline and by -pass line and decides the sewer import and meets, is equipped with the electrical control valve that concatenates with electric valve in the flow control pipeline, is equipped with electric valve in by -pass line, the aperture of company's flowing back position control electrical control valve that the controller of device was gathered according to the level gauge, accurate control blow down flow when the electrical control valve is malfunctioning or during a large amount of blowdown of need, is opened electric valve among the by -pass line, is closed electric valve in the flow control pipeline simultaneously through the controller, realizes urgent blowdown. The device overall structure is compact, and occupation space is little, save material, realize deciding to arrange and linking the automated control who arranges through the controller, use manpower sparingly reinforcing system security, system maintenance work volume alleviates the NULL of being convenient for.
Description
Technical field
The utility model relates to boiler accessory machinery, particularly a kind of boiler blow-off flash chamber.
Background technology
The blowdown mode of boiler is divided two kinds of continuous blowdown and periodical blowdowns. Continuous blowdown is from boiler water cycle loop in steamdrumThe position of salt concentration maximum emits a pot water continuously, to maintain the specified salt content of pot water in closed circuit; Periodical blowdown is supplementaryThe deficiency of continuous blowdown is got rid of the sediment in drum from boiler water drum and header, to improve the quality of pot water.
Blowdown dilatancy device for pressure Industrial Boiler (or waste heat boiler) comprises platoon (abbreviation of continuous blowdown flash tank)With determine row's (abbreviation of regular unloading container). Platoon and determine mining and get the sewer dilatation flash distillation of boiler is realized to steam and sewageSeparate, the steam that platoon is separated is got back to (cause oxygen-eliminating device) in therrmodynamic system recycling, the unevaporated sewer of platoon and potThe periodical blowdown of stove together enters determines row, determines all outer rows of the raw indirect steam of scheduling and sewage.
Existing middle pressure Industrial Boiler (or waste heat boiler) blowdown dilatancy device is to determine row and platoon as two autonomous device clothPut, the two connects by long and complicated pipe arrangement, takes manually to control separately. Its shortcoming is that equipment occupation space is large, disappearsConsumption material is many; Control manually with the control system of boiler and disconnect, not only labor intensive, and be difficult to ensure blowdown flowAccurately control, affect the security of system; The maintenance load of device is large, and inconvenient production management.
Utility model content
For overcoming the shortcoming of above-mentioned prior art, the purpose of this utility model be to provide one take up room little, take automation controlThe boiler blow-off flash chamber of system.
Realize the boiler blow-off flash chamber of above-mentioned purpose, comprise platoon and determine row; Described platoon and fixed row are arranged on same establishingOn standby chassis; Platoon outlet of sewer is by flow adjustment pipe parallel with one another and bypass line and determine sewer import and join,The electric control valve being connected in series with two electrically operated valves respectively before and after being provided with in flow adjustment pipe is provided with an electricity in bypass lineMovable valve; Device is provided with controller, and controller gathers by wire the platoon liquid level signal that the liquid level gauge on platoon detects, according toThe keying of electrically operated valve in the aperture of electric control valve and flow adjustment pipe and bypass line described in the control of platoon liquid level.
Compared with prior art, the utility model has the advantages that:
1, will determine row and platoon install concentratedly on same chassis, by UNICOM's pipeline shorter and simple in structure (parallel connectionFlow adjustment pipe and bypass line) interconnect, make device compact overall structure, take up room and dwindle, save material, haveBe beneficial to reduction equipment investment;
2, realize the automation control of fixed row and platoon by controller, not only save manpower, and blowdown flow precise control,Security of system strengthens;
3, system maintenance workload alleviates, and is convenient to production management;
4, device can adopt modularized design, and the boiler that difference is exerted oneself can carry out type selecting according to the actual requirements, is conducive to shorten designDuration, improve design efficiency.
Brief description of the drawings
Accompanying drawing is the utility model structural representation.
In figure: 1-platoon, 2-fixed row, 3-electric control valve, 4-electrically operated valve, 5-controller, 6-liquid level gauge, aThe import of-platoon sewage, b-platoon indirect steam outlet, c-determine sewer import, d-surely arrange indirect steam outlet, e-fixed rowOutlet of sewer, f-platoon outlet of sewer.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the platoon 1 of the utility model boiler blow-off flash chamber and surely to arrange 2 profiles be cylindrical vertical tank body,Its structure is same as the prior art: in platoon, establish dividing plate and shutter steam-water separator (not shown), tank body be provided with liquid level gauge,Safety valve and Pressure gauge, platoon upper side has platoon sewage import a, and platoon indirect steam outlet b is arranged at top, and platoon dirt is arranged at bottomWater out f; Fixed row's tank body is provided with Pressure gauge, and surely arranging lower side has the sewer of determining import c, and the row's of determining indirect steam is arranged at topOutlet d, there is the sewer of determining outlet e lower end.
This device by platoon and fixed row mutually close, be arranged in same equipment chassis (not shown). Platoon outlet of sewer f is logicalCross flow adjustment pipe parallel with one another and bypass line and determine sewer import c and join, before and after being provided with in flow adjustment pipeThe electric control valve 3 being connected in series with two electrically operated valves 4 is respectively provided with an electrically operated valve 4 in bypass line.
The controller 5 of device connects together with the control system of boiler, and the liquid level gauge 6 that controller gathers on platoon by wire is examinedThe platoon liquid level signal of surveying, according to the aperture of platoon liquid level control electric control valve 3, the essence of blowdown flow while realizing normal blowdownAccurate control; In the time that electric control valve is malfunctioning or need when a large amount of blowdown, opens electrically operated valve in bypass line, together by controllerTime close the electrically operated valve in flow adjustment pipe, carry out urgent blowdown. Controller can be realized detection, control and long-range logical simultaneouslyTelecommunication function.
The blowdown flow process of device is: enters platoon from the continuous blowdown water of boiler by platoon sewage import a and carries out dilatation flash distillation,Realize steam and separate with sewage, and obtain indirect steam by the further separation of the interior shutter steam-water separator of establishing, secondary steamsVapour is sent outside from the indirect steam outlet b of platoon, is back in boiler heating power system, and the sewage that platoon outlet of sewer f discharges passes throughFlow adjustment pipe enters and determines row and carry out dilatation flash distillation by determining sewer import c together with boiler periodical blowdown water, realizes steamSeparate with sewage, the indirect steam of generation and sewage respectively by surely arrange indirect steam outlet d and determine sewer export e directly outsideRow.
