Abstract

The utility model relates to an anti-blocking atomizing nozzle. The anti-blocking atomizing nozzle has the advantages of being not prone to being blocked, good in cooling effect, simple in structure and easy to maintain, and therefore desuperheating water can be stably provided for equipment. According to the technical scheme, the anti-blocking atomizing nozzle comprises a nozzle body, a trumpet-shaped water outlet and a trumpet-shaped water inlet are formed in the left side and the right side of the nozzle body respectively, and the water outlet and the water inlet are communicated through a tubular channel. The anti-blocking atomizing nozzle is characterized in that the position of the water outlet is covered with a protection sleeve, and a plurality of filter holes are evenly distributed in the outer circumferential face and the end face of the protection sleeve.

Description

Anti-blocking atomizer

Technical field

The utility model relates to a kind of cooling device, specifically a kind of atomizer.

Background technology

In steam turbine condensing system, the low discharge cooling jet that the hydrophobic expansion tank of condenser and bypath system intermediate pressure by-pass use generally includes following two kinds of structures: 1, atomizer (as shown in Figure 2), this atomizer is adapted at using in situation that injection flow rate is less, and its larynx footpath is in 3mm left and right; 2, sparge pipe (as shown in Figure 3), this sparge pipe is shaped with the hole for water spraying of some diameters below 2mm.

In running, be that atomizer or sparge pipe all very easily stop up, cannot be reliably for the hydrophobic expansion tank of condenser and bypath system intermediate pressure by-pass stably provide desuperheating water, need further improvement.

Utility model content

The purpose of this utility model is the deficiency overcoming in above-mentioned background technology, and a kind of anti-blocking atomizer is provided, and this nozzle should have difficult obstruction, temperature lowering effect is good, simple in structure and be easy to the feature of safeguarding, thereby can be stably for equipment provides desuperheating water.

The technical solution of the utility model is: anti-blocking atomizer, comprise nozzle body, and the left side of described nozzle body and right side are shaped with respectively trumpet-shaped delivery port and water inlet, between described delivery port and water inlet, are communicated with by a tubular conduit; It is characterized in that: described water inlet position is cover cap one protective jacket also, on the outer circumference surface of described protective jacket and end face, all arranging some filtering holes.

Described nozzle body and protective jacket are connected as a single entity.

The aperture of described filtering holes is less than the diameter of tubular conduit.

The beneficial effects of the utility model are:

1, structural design of the present utility model is comparatively reasonable, in running, can not stop up, and desuperheating water can be stably provided, without the surplus that increases circulation area;

2, water spraying atomization of the present utility model is effective, has good temperature lowering effect;

3, of the present utility model simple and compact for structure, be easy to safeguard, dismounting and cleaning be very easy to.

Detailed description of the invention

Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.

As shown in Figure 1, anti-blocking atomizer, comprises nozzle body 1; The left side of described nozzle body and right side refer to respectively be shaped with trumpet-shaped delivery port 1-1 and water inlet 1-2, between described delivery port and water inlet, are communicated with (for venturi tube structure) by a tubular conduit 1-3.

Above structure is identical with atomizer of the prior art (as shown in Figure 2).

Improvements of the present utility model are:

On the water inlet of described nozzle body, also install a protective jacket 2 additional, described protective jacket and nozzle body are one-body molded; In the outer circumference surface of described protective jacket and its right end face, all arranging some filtering holes 2-1, the aperture of described filtering holes is less than the diameter of tubular conduit.

Described filtering holes can be in the situation that ensureing injection flow rate, effectively prevents from entering in centre gangway and causing and tubular conduit obstruction greatly reduce blocking probability compared with bigger material; And in the time that part filtering holes is stopped up, injection flow rate also can obviously not reduce;

The utility model is connected with the flange (omitting in figure) being arranged on blind plate by helicitic texture (omitting in figure), on the outer circumference surface of described nozzle body, is shaped with respective threaded, makes the utility model be easier to install, clear up, change and remove.

In figure, arrow is water movement direction.

Claims
