Abstract
The invention provides a water-spraying type cooling device of a boiler super-heater. An original cooler of the boiler super-heater is sealed too inexactly and supported too weakly to cause unqualified product and seriously affect the reliability of the product. The water-spraying type cooling device comprises a cooling mixing box (1); an inner sleeve (2) is arranged in the cooling mixing box; the inner sleeve runs through a build-in supporting beam (3); one side of the cooling mixing box is connected with a steam inlet connection pipe (4); the other side of the cooling mixing box is connected with a steam feed connection pipe (5); a water drain connection pipe (6) is connected below the cooling mixing box; a group of atomizing nozzles (7) are connected on the cooling mixing box; and the atomizing nozzles are connected by a connecting pipe (8); the connecting pipe is connected with a condensed water connection pipe (10) by a three-way connector (9); and a thermoelectric couple (11) is arranged in the cooling mixing box (1). The device provided by the invention is used for cooling the boiler super-heater.
Description
Technical field
The present invention relates to a kind of chemical machinery, be specifically related to a kind of spray desuperheating device of boiler superheater.
Background technology
Adopt one group of dog screw and two groups of supporting screws to guarantee mutual position and relative expansion between traditional superheater attemperator inner sleeve and attemperator stack shell, traditional screw fixed form is the external screw, and promptly screw passes the attemperator stack shell and fixes inner sleeve; During this structure welding; Because being prone to crack, the influence of postwelding thermal stress, screw and stack shell junction cause revealing, or because welding deformation; Screw can not be well fixing inner sleeve, be prone to vibration during operation and destroy attemperator.Dog screw and supporting screw on the former boiler superheater attemperator stack shell are external; Because sweating heat stress influence; Be prone to during the fixing welding of external screw stack shell occur crackle or poorly sealed, support not in place and produce defective products, have a strong impact on reliability of products.
Summary of the invention
The objective of the invention is to provide a kind of spray desuperheating device of boiler superheater, avoid the heat fatigue of stack shell to destroy boiler overheating to the problem of above-mentioned existence.
Above-mentioned purpose realizes through following technical scheme:
The spray desuperheating device of boiler superheater comprises the desuperheat blending bin, and inner sleeve is equipped with in described desuperheat blending bin the inside; Described inner sleeve passes built-in brace summer; One side of described desuperheat blending bin connects admission takes over, and the opposite side connection of described desuperheat blending bin send vapour to take over the following connection drain nozzle of described desuperheat blending bin; Connect one group of atomizer in the described desuperheat blending bin; Connect through joining pipe between the described atomizer, described pipe connects condensate through three-way connection to be taken over, and in the described desuperheat blending bin thermocouple is installed.
Be connected fixing between the spray desuperheating device of described boiler superheater, described built-in brace summer and described inner sleeve through built-in supporting screw.
The spray desuperheating device of described boiler superheater, described atomizer adopts cecum nozzle or threeway nozzle.
The spray desuperheating device of described boiler superheater, described atomizer are 3.
Beneficial effect:
1. the present invention what of the amount of sending into of condensate of condensing pump from the beginning through control; Come the steam that gets into this device is carried out dynamic desuperheat control and regulation; Monitor the temperature value of the mixed vapour in this device constantly by thermocouple; After the temperature that reaches setting valve, fix with being about to the valve opening that condensate sends on the pipeline, no longer regulate valve opening on the pipeline.This device in use carries out once the inspection of vapor (steam) temperature parameter in this device week about; Also can thermocouple be adopted the model with 4～20mA output signal; This signal is sent to the main control room of steam turbine; Carry out long-range demonstration and keep watch on, will adopt the form valve of charged control to carry out remote control operation from the valve on the water lines of coagulating pump simultaneously, revise temperature data simultaneously at any time and reach setting valve.
2, the present invention is simple in structure, and is easy to maintenance, and Installation and Debugging are easy; The structure of component part of the present invention, material and manufacturing process are all very simple, with low cost, and renewal part is convenient, has good and economic.
