Abstract
The utility model relates to a spray attemperator with an improved liner structure, which comprises a liner and is characterized in that the liner consists of non-flat plates. The spray attemperator has the advantages that the spray attemperator has fine fatigue resistance, contact surface of attemperating water dropping onto the liner so that attemperating water can be evaporated quickly, and longitudinal rigidity of the liner is increased so that the spray attemperator has long service life.
Description
Technical field
The utility model relates to a kind of direct-contact desuperheater that improves the neck bush structure that has, and belongs to the boiler desuperheater parts in power plant.
Background technology
Attemperator is to be used for the important device of steam regulation boiler steam temperature.In the thermal power plant,, can make parts damages such as boiler turbine or cause a serious accident if there is not attemperator just the vapor (steam) temperature of boiler export cannot be controlled in the rated range.The adjusting of vapor (steam) temperature can be divided into two big classes: fume side is regulated and steam side is regulated.Direct-contact desuperheater is the main means of steam side steam regulation temperature.Direct-contact desuperheater all is provided with the neck bush of thin-walled, its objective is to avoid atomizing the thermal shock of incomplete desuperheat water droplet to heavy wall header or connecting pipe inwall.When thicker desuperheating water drops onto on the neck bush, because neck bush accumulation of heat inertia is little, just can water droplet be gasified the less temperature difference rapidly, the thermal stress that produces on neck bush is little.
As shown in Figure 1, be traditional direct-contact desuperheater structural representation, Fig. 2 is its cutaway view, and described traditional attemperator is made up of cylindrical shape neck bush 2, cylindrical shell 3 and nozzle 4.Described neck bush is to process with light-wall pipe or steel plate.There are the very big temperature difference in desuperheating water and neck bush; when desuperheating water is sprayed onto on the neck bush; can cause the rapid variation of neck bush temperature; thereby generation thermal stress; thermal stress changes can produce heat fatigue cracking and linear deformation, causes the neck bush breakage, loses the protective effect to the attemperator cylindrical shell; if damaged neck bush comes off go in the hot side pipe, also can cause accidents such as booster with air-flow.
Summary of the invention
The purpose of this utility model provide a kind of safe and reliable, anti-fatigue performance good, the direct-contact desuperheater of long service life.
In order to realize above purpose, the technical solution of the utility model provides a kind of direct-contact desuperheater that improves the neck bush structure that has, and comprises neck bush, it is characterized in that described neck bush is made up of non-tablet.
Further, described non-tablet is a corrugated plating.
Described non-tablet is folding shape plate.
The utility model has the advantages that:
A. safe and reliable;
B. anti-fatigue performance is good;
C. increase desuperheating water and drop onto contact-making surface on the neck bush, desuperheating water is gasified rapidly;
D. improve neck bush rigidity longitudinally;
E. long service life.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1
As shown in Figure 3, be a kind of direct-contact desuperheater structural representation, Fig. 4 is its cutaway view, and described direct-contact desuperheater is made up of neck bush 1, cylindrical shell 3 and nozzle 4.Described neck bush 1 is formed by the corrugated plating manufacturing.The external diameter of neck bush 1 need cooperate the attemperator cylindrical shell.
When desuperheating water was sprayed onto on the neck bush 1, neck bush 1 radially can free shrink expand, and it is very little that thermal stress changes the influence that the intralamellar part structure is caused, thereby anti-fatigue performance is good, can increase the service life, safe and reliable during operation.
As shown in Figure 5, be a kind of direct-contact desuperheater structural representation, Fig. 6 is its cutaway view, and described direct-contact desuperheater is made up of neck bush 1, cylindrical shell 3 and nozzle 4.Described neck bush 1 is formed by the manufacturing of folding shape plate.The external diameter of neck bush 1 need cooperate the attemperator cylindrical shell.
When desuperheating water was sprayed onto on the neck bush 1, neck bush 1 radially can free shrink expand, and it is very little that thermal stress changes the influence that the intralamellar part structure is caused, thereby anti-fatigue performance is good, can increase the service life, safe and reliable during operation.
Claims (3)
