Technical field
This utility model is related to preventer, in particular it relates to a kind of condenser and turbine generating system, this condenser
Preventer including the cooling tube in protection condenser.
Background technology
Condenser is a kind of heat exchanger that gas turbine exhaust gas are condensed into water, and the cooling tube in condenser is important composition portion
Point, finish the steam after work(full of steam turbine outside cooling tube, steam carries out heat exchange by the cooling water in cooling tube interior circulation
After be formed as condensate, condensate can be recovered and be continuing with systems afterwards, therefore to the water quality requirement of condensate very
Height, and cooling water can be the poor water of the water quality such as general sea water or river.
In addition, the top of condenser is provided with low-pressure internal cylinder, high-temperature steam can be expelled to condenser from low-pressure internal cylinder, is
Prevent the Low Temperature Steam outside low-pressure internal cylinder from can absorb the high-temperature steam in low-pressure internal cylinder, typically set on the outer wall of low-pressure internal cylinder
The heat shield put assembled soldering stainless steel plate and make, to prevent the thermal loss of high-temperature steam.But, in unit running process
In, the steam discharge due to low-pressure internal cylinder can impact low-pressure internal cylinder outer wall at a high speed, accordingly also can impact heat shield and ftracture, this
When planting the long term impacting, heat shield can dislodge and fall in condenser from the outer wall of low-pressure internal cylinder, thus injuring tube wall by a crashing object relatively
Thin cooling tube (it should be noted that also have other Work tools or part drops and injures cooling tube by a crashing object), leads to cooling tube to break
Split, now the cooling water in cooling tube leaks in the condensate after cooling in a large number, the poor cooling water pollution condensate of water quality,
If the leak stopping of cooling tube operates not in time, steam-turbine unit emergency shutdown can be led to, economic loss is big.
Accordingly, it would be desirable to solve the problems, such as cooling tube in condenser by the impact of foreign and tube wall ruptures.

Specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the present utility model is described in detail.It should be appreciated that herein
Described specific embodiment is merely to illustrate and explains this utility model, is not limited to this utility model.
This utility model provides a kind of condenser, and (Fig. 1 and Fig. 2 illustrate only the part of condenser as depicted in figs. 1 and 2
Structure), this condenser includes housing 1, the cooling tube 3 being arranged in described housing 1 and is arranged on the top of described cooling tube 3
Low-pressure internal cylinder 2, wherein, is provided with preventer 4, this preventer 4 wraps between described low-pressure internal cylinder 2 and described cooling tube 3
Include the bracing frame 5 of the top being arranged on described cooling tube 3, the protection network 6 being provided with support frame as described above 5.
Due to being provided with preventer 4 above cooling tube 3 such that it is able to stop foreign body (for example, from being arranged on low pressure
The heat shield coming off on the outer wall of inner casing 2) injure cooling tube 3 by a crashing object, to protect cooling tube 3, simultaneously because the protection network of preventer 4
6 is network structure, therefore, it is possible to make steam normally circulate in condenser.
Preferably, described protection network 6 is made up of tinsel, and tinsel can be iron wire, copper wire, rustless steel
Or nickel wire etc., tinsel fully can stop the impact strength of the foreign body dropping, and constitutes protection network by the tinsel of hardness is bigger
6, the life-span of protection network 6 can be improved.
Further, described material wiry preferably employs stainless steel silk, it is highly preferred that being employed as Austenitic
The decay resistance of 1cr18ni9ti, 1cr18ni9ti is strong, therefore in the condenser being in steam ambient, but this
Utility model does not limit concrete material wiry or other iron wires as above or copper wire etc., as long as tinsel
Be formed as netted so that steam normally circulates in condenser.
In addition, the size according to the heat shield on the outer wall being arranged on low-pressure internal cylinder and the shadow for steam circulation area
Ring, for the cooling tube for 0.5mm or 0.7mm for the thickness, the preferred implementation providing as this utility model, described protection network
6 mesh be preferably sized to 80*80mm to 120*120mm, more preferably 100*100mm, protection network 6 is in this size
Under, injuring by a crashing object of the foreign bodies such as the heat shield that cooling tube 3 dropped can either be protected, and do not affect the circulation of steam that is to say, that working as
When the size of the mesh of protection network 6 is more than 120*120mm, steam circulation is had little to no effect, but it is possible to pass through protection network
The impulsive force of the size of 6 foreign body is larger and cooling tube 3 may be smashed, when protection network 6 mesh size be less than 80*80mm
When, big foreign matters can protect cooling tube 3 by protection network 6, but the too small circulation that can lead to steam of mesh is obstructed,
Thus the heat exchange efficiency of condenser can be reduced.Certainly, here is it should be noted that condenser for different size or type,
The principle that the size of the mesh of protection network 6 should meet is: is prevented from passing through enough to the foreign body injuring cooling tube by a crashing object, and does not affect
The circulation area of steam.
In addition, the bracing frame 5 of preventer 4 is connected on the housing 1 of condenser, preferably it is removably attachable to housing
On 1, and bracing frame 5 is arranged horizontally at the top of cooling tube 3 so that the protection network 6 being arranged on bracing frame 5 is in water
Square equably stop the foreign body dropping from top upwards.
Additionally, for the barrier propterty increasing preventer 4, being provided with multiple protection between low-pressure internal cylinder 2 and cooling tube 3
Device 4, multiple protection fill 4 and abreast arrange along short transverse and form multilayer proofing device 4, thus, open at low-pressure internal cylinder 2
The foreign bodies such as the heat shield that the beginning drops can be through multilayer proofing device 4 during dropping, and this structure constitutes multilamellar and hinders,
Whole foreign body is difficult to damage cooling tube 3.
In addition, it should be noted that the preventer 4 in the condenser that this utility model should be provided regularly is tieed up
Shield and maintenance, for example, cleaning remains in the foreign body on protection network.
This utility model provides a kind of turbine generating system again, and this turbine generating system includes steam turbine, wherein, should
The condenser that this utility model that turbine generating system also includes being connected with described steam turbine provides.Because this utility model carries
For condenser in be provided with protect cooling tube 3 damaged preventer 4, therefore condenser security performance improve and
Life-span is elongated, and condenser stably can carry out heat exchange effect to steam turbine.
Describe preferred implementation of the present utility model above in association with accompanying drawing in detail, but, this utility model does not limit
Detail in above-mentioned embodiment, in range of the technology design of the present utility model, can be to skill of the present utility model
Art scheme carries out multiple simple variant, and these simple variant belong to protection domain of the present utility model.
It is further to note that each particular technique feature described in above-mentioned specific embodiment, in not lance
In the case of shield, can be combined by any suitable means, in order to avoid unnecessary repetition, this utility model is to each
Plant possible compound mode no longer separately to illustrate.
Additionally, combination in any can also be carried out, as long as it is not disobeyed between various different embodiment of the present utility model
Carry on the back thought of the present utility model, it equally should be considered as content disclosed in the utility model.
