Abstract
The utility model discloses a desuperheating water nozzle which comprises an outer shell connected with a desuperheating water pipe, wherein an upper end of the outer shell is arranged on the desuperheating water pipe in a communicated mode, the lower end of the outer shell is connected with a seal cover, and a spray port is formed in the middle of the seal cover. The side wall of a rotational flow cylinder is provided with a rotational flow channel inclined along the same direction, the rotational flow cylinder is arranged inside the outer shell and is connected with the seal cover, and a top cover is connected to the upper end of the rotational flow cylinder. The desuperheating water nozzle can guarantee adequate atomization of desuperheating water, and therefore the contact area of the desuperheating water and vapor is increased, and heat exchange efficiency is improved.
Description
Technical field
The utility model relates to power station dewatering capacity-enlarging apparatus field, relates in particular to desuperheating water shower nozzle field.
Background technology
Hydrophobic is the condensate water that steam produces because of pressure, drop in temperature in pipeline, and the condenser in the water circulation system etc. is had larger harm.Hydrophobic development unit is that hydrophobic in the pressure hydrophobic pipeline carried out the dilatation step-down, reduces steam pressure wherein, and its operation principle is to spray desuperheating water to high steam, so that the part high steam becomes liquid state from gaseous state, thereby realizes the step-down dilatation.
In the existing hydrophobic development unit, desuperheating water directly sprays from the desuperheating water water-supply-pipe, and it is abundant not to atomize, and is not high with little, the effective heat transfer rate of contact area of steam.
The utility model content
Atomizing available heat incomplete, desuperheating water exchanged the problem of rate variance when the applicant sprayed for existing hydrophobic development unit desuperheating water, improve research, a kind of desuperheating water shower nozzle is provided, can guarantee that desuperheating water fully atomizes, thereby increase contact area, the raising rate of heat exchange of desuperheating water and steam.
Technical side of the present utility model is as follows:
A kind of desuperheating water shower nozzle comprises the shell that is connected with the desuperheating water water-supply-pipe; The upper end communication apparatus of described shell is on the desuperheating water water-supply-pipe, and its lower end is connected with seal cover, and described seal cover middle part has spout; Offer the eddy flow passage along same incline direction on the sidewall of whirl cylinder, described whirl cylinder is installed in the described shell and with described seal cover and is connected, and the upper end of described whirl cylinder is connected with top cover.
Its further technical scheme is: the middle part of described top cover has jet orifice.
The beneficial effects of the utility model are:
Desuperheating water is in the desuperheating water water-supply-pipe enters the utility model shell, and the spin current passage enters whirl cylinder, and the spout from the bottom behind the formation eddy flow sprays, thereby improves the fogging degree of desuperheating water, increases the contact area of desuperheating water and steam; After desuperheating water enters the utility model shell, still maintain certain pressure, thereby can from described jet orifice, enter described whirl cylinder, the eddy flow that drives the formation of spin current passage sprays spout fast, accelerate the flow velocity of desuperheating water, thereby further strengthen atomizing effect, improve the rate of heat exchange of desuperheating water.
Description of drawings
Fig. 1 is that master of the present utility model looks cutaway view, and wherein the desuperheating water water-supply-pipe does not draw.
Fig. 2 is the cutaway view of A-A among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1 and Figure 2, the utility model comprises shell 1, whirl cylinder 3 and seal cover 4; The upper end sealing device of shell 1 is on the desuperheating water water-supply-pipe, and with it connection; Its lower end is welded with seal cover 4, and seal cover can also be connected with shell by forms such as flanges, and seal cover 4 middle parts have spout 5.Offer the eddy flow passage 6 along same incline direction on the sidewall of whirl cylinder 3.Whirl cylinder 3 is installed in the shell 1 and with seal cover 4 and is welded to connect.The upper end of whirl cylinder 3 is welded with top cover 2, and top cover 2 middle parts have jet orifice 7.
During work, desuperheating water is in the desuperheating water water-supply-pipe enters shell 1, and the eddy flow passage 6 of spin current cylinder 3 sidewalls enters whirl cylinder 3, after forming eddy flow, ejection in the spout 5 from seal cover 4, thereby the fogging degree of raising desuperheating water, the contact area of increase desuperheating water and steam; After desuperheating water enters shell 1, still maintain certain pressure, thereby can from jet orifice 7, enter the inside of whirl cylinder 3, the eddy flow that drives 6 formation of eddy flow passage sprays spout 5 fast, accelerate the flow velocity of desuperheating water, thereby further strengthen atomizing effect, improve the rate of heat exchange of desuperheating water.
More than describing is to explanation of the present utility model, is not to restriction of the present utility model, and the utility model limited range is referring to claim.In the situation of the utility model basic structure, the utility model can be done any type of modification.
