Description
Technical field
The present invention relates to a kind of drain tank, and in particular to a kind of automatic sparse water tank.
Background technology
The gland heater in thermal power plant is shell-and-tube heat exchanger, and shell-side receives steam turbine gland seal system leakage vapour, through tube side
Drain recovery is to condenser after cooling, condensation.When condenser is normally run be vacuum, for avoid it is hydrophobic be evacuated, influence condensing
Device runs vacuum, hydrophobic typically to use U-shaped water sealing (sealing water) pipe, and steam and air communication passages are sealed with water-column.
The conventional water sealing (sealing water) pipe pattern of current power plant has single-stage water seal and multilevel water seal.
Single-stage water seal and multilevel water seal some problems of generally existing in power plant runs, single-stage water seal due to water seal height not
The reason for enough or medium is vaporized, easily causes water seal and is evacuated, and front end steam influences main frame vacuum directly into condenser；It is many
Level water seal is composed in series by some single-stage water seals, due to impurity or computed altitude influence, easily causes blocked drain.
The structural volume of single-stage and multilevel water seal is larger, and consumptive material is more during construction, and construction is complicated, and needs occupancy larger
Space, if being embedded in ground end, easily by surrounding base construction infection, causes water sealing (sealing water) pipe flexural deformation, while also easily there is debris to fall into
Wherein, after impurity enters water sealing (sealing water) pipe, accumulate in U-tube road, it is difficult to check and remove, through-flow face is caused after long-play
Product reduces, blocked drain, influences the normal operation of water sealing (sealing water) pipe.
The content of the invention
To solve the deficiencies in the prior art, it is an object of the invention to provide a kind of size is small, construct simple, operation safety
Reliable automatic sparse water tank.
In order to realize above-mentioned target, the present invention is adopted the following technical scheme that：
Cabinets cavity is divided into inhalant region and exhalant region by a kind of automatic sparse water tank, dividing plate, and the inhalant region is provided with water inlet, gone out
Pool is provided with the delivery port with capping；The capping connection ball float.
Above-mentioned inhalant region is connected with exhalant region at the top of dividing plate.
Above-mentioned capping blocks delivery port by spring so that not enough in ball float pulling force, or under no floating ball state of tension, capping
Delivery port is blocked by spring.
The height of above-mentioned delivery port is less than the overhead height of dividing plate.
The working depth of above-mentioned ball float is less than the overhead height of dividing plate.
Above-mentioned inhalant region and exhalant region bottom is respectively equipped with sewage draining exit, and the water accumulated for a long time is removed by sewage draining exit and is become silted up,
Play clean box body, prevent that the water of aqueous silt from discharging the mouth of a river, and expand the useful space of casing retaining.
The height of above-mentioned delivery port is higher than sewage draining exit, further prevents that water from becoming silted up and is discharged by delivery port.
Above-mentioned ball float is connected with casing, it is to avoid ball float scope of activities is excessive, is damaged.
The present invention is advantageous in that：A kind of automatic sparse water tank of the present invention, current electricity is replaced using drain tank pattern
The single-stage water seal commonly used in factory and multi-level water tube sealing, dividing plate subregion is used in drain tank, using automatic ball float controlling water level, automatically
Close delivery port；Its small volume, greatly reduces the difficulty of construction and quantities of water seal built-in pipe, while water seal quilt can be avoided
Evacuate or the situation of blocked drain occurs, improve the security of draining system operation, and be this area to arranging no particular/special requirement
The preferred arrangement in domain provides condition advantageously.Solve that conventional u-shaped water sealing (sealing water) pipe constructional difficulties, water seal effect be bad and difficulty
The problem of with repair and maintenance.
A kind of automatic sparse water tank characteristics of compact layout of the present invention, builds, safeguards simple, occupation of land size is small, easy construction, operation
It is safe and reliable, with very strong practicality and wide applicability.
Brief description of the drawings
Fig. 1 is a kind of structural representation of automatic sparse water tank of the present invention.
The implication marked in accompanying drawing is as follows：1st, casing, 2, dividing plate, 3, water inlet, 4, delivery port, 5, ball float, 6, sewage draining exit.
Embodiment
Make specific introduce to the present invention below in conjunction with the drawings and specific embodiments.
By taking 300MW grade units as an example, automatic sparse water tank is a rectangular box 1, and appearance and size length, width and height are respectively 600
×600×800mm.Automatic sparse water tank may be arranged at ground or pipe hole bottom, and 2 points of 1 inner-use clapboard of casing is inhalant region and water outlet
Area, the automatic valve of ball float 5 of water lev el control is equipped with exhalant region, controls the capping of delivery port 4.Delivery port 4 connects condenser.
During work,
Service pressure is atmospheric pressure, when just starting working, and inhalant region and exhalant region are without water level, now exhalant region ball float 5
Valve is fallen, and seals delivery port 4.
When unit puts into operation, gland heater have it is hydrophobic inhalant region is entered by water inlet 3, with hydrophobic increase,
Inhalant region water level is constantly raised, when water level exceedes 2 top of dividing plate, hydrophobic overflow to exhalant region.
Ball float 5 is opened on buoyancy top after exhalant region water level reaches preset height, pulls spring to open delivery port 4, hydrophobic to solidifying
Vapour device draining, ball float 5 is with water level decreasing after draining, because spring effect capping seals delivery port 4, to maintain condenser system
Vacuum.
The basic principles, principal features and advantages of the present invention have been shown and described above.The technical staff of the industry should
Understand, the invention is not limited in any way for above-described embodiment, it is all to be obtained by the way of equivalent or equivalent transformation
Technical scheme, all falls within protection scope of the present invention.
