Description
Technical field
The utility model relates to a kind of nitrogen protection device, particularly a kind of chilled brine nitrogen seal device.
Background technology
What chilled water system adopted is that glycol water is as refrigerating medium, pipeline adopts carbon steel piping, in use, find the lengthening along with running time, darkening of chilled water, chilled water pH value changes simultaneously, and three freezing unit operations do not break down for a long time in succession, and dismounting discovery is that chilled brine causes damaging after evaporimeter corrosion.Through checking that discovery forms acidic materials cause impurity in equipment corrosion and solution to increase because chilled water to contact with oxygen in air to cause to be oxidized, cause device damage.
Utility model content
The technical problem that the utility model solves is to provide a kind of chilled brine nitrogen seal device, avoids chilled water to contact with air, causes chilled water to be oxidized.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of chilled brine nitrogen seal device, is characterized in that: comprise normal pressure chilled brine storage tank, liquid seal can, blow-down tank, magnetic valve, coupling cock, pressure of storage tank transmitter and pipeline,
Normal pressure chilled brine storage tank, its top is provided with an outlet, is connected with liquid seal can top inlet by pipeline A, pressure of storage tank transmitter that pipeline A connects;
Magnetic valve, it is connected with pipeline B, and pipeline B is in parallel with pipeline A;
Liquid seal can, its top is provided with an import and an outlet, and import is connected with pipeline A, exports and is connected with the import at blow-down tank top by pipeline C, and its side is provided with an outlet, is connected with blow-down tank bottom inlet by pipeline D, coupling cock that pipeline D connects.
Blow-down tank, its top is provided with an import and an outlet, and import is connected with liquid seal can by pipeline C, and export and be connected with air, side is provided with an import, is connected with coupling cock by pipeline D with liquid seal can side exit.
Further, be provided with sealing fluid in described liquid seal can, the liquid level of described sealing fluid is higher than described side exit.
Further, described pipeline C is passed into the inside of described sealing fluid.
The utility model has the advantage of:
(1) each parts of the utility model connect compact, reasonable in design, and cost is lower, utilizes nitrogen protection, avoids chilled water to contact with air and causes chilled water to be oxidized;
(2) liquid seal can of the present utility model circulates with blow-down tank and is connected, and sealing fluid can be made to recycle, reduce unnecessary cost.
Accompanying drawing explanation
Fig. 1 is a kind of chilled brine nitrogen seal device of the utility model structural representation.
Detailed description of the invention
As shown in Figure 1, normal pressure chilled brine storage tank 1, liquid seal can 2, blow-down tank 3, magnetic valve 4, coupling cock 5, pressure of storage tank transmitter 6, pipeline A7, pipeline B8, pipeline C9, pipeline D10 and sealing fluid 11 is comprised.
Normal pressure chilled brine storage 1, its top is provided with an outlet, is connected, pipeline A7 has installed pressure transmitter 6 by pipeline A7 with liquid seal can 2 top inlet;
Magnetic valve 4, it is connected with pipeline B8, and pipeline B8 and pipeline A7 is connected;
Liquid seal can 2, its top is provided with an import and an outlet, and import is connected with pipeline A7, outlet is connected with the import at blow-down tank 3 top by pipeline C9, its side is provided with an outlet, is connected with blow-down tank 3 bottom inlet by pipeline D10, coupling cock 5 that pipeline D10 connects.
Blow-down tank 3, its top is provided with an import and an outlet, and import is connected with liquid seal can 2 by pipeline C9, and export and be connected with air, side is provided with an import, is connected with coupling cock 5 by pipeline D10 with liquid seal can 2 side exit.
Be provided with sealing fluid 11 in liquid seal can 2, the liquid level of described sealing fluid 11 is higher than described side exit.
Described pipeline C9 is passed into the inside of described sealing fluid 11.
As the utility model embodiment more specifically:
Nitrogen is connected with pipeline A7, magnetic valve 4, liquid seal can 2 with normal pressure chilled brine storage tank 1 by pipeline B8, carries out chain control by pressure of storage tank transmitter pressure 6 and magnetic valve 4 switch, ensures pressure-fired 50-70mm water column in storage tank, with air exclusion.Time as malfunctioning in magnetic valve 4, pressure of storage tank is excessive, breaks through fluid-tight layer and carries out direct emptying, and ensure that pressure of storage tank can not be too high, the sealing fluid 11 in liquid seal can 2 is back in liquid seal can 2 by bottom coupling cock 5 again, ensures the recycling of sealing fluid 11.Which reduce the effect of oxygen to chilled water, increase substantially the service life of handpiece Water Chilling Units.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
