Abstract
The utility model discloses an atmospheric drainage flash tank, the main body of the atmospherical drain flash tank is a steel pipe, and a desuperheating water spray pipe interface and a drainage collecting pipe interface are arranged on the wall of the steel pipe from top to bottom. The atmospheric drainage flash tank has the advantage that a drainage, capacity expansion and emission device for a pipeline, which is simple in structure and convenient to operate, is provided. By adopting the atmospheric drainage flash tank, the problem that the capacity expansion ability of the drainage flash tank of a high-capacity and high-parameter steam turbine body is insufficient is solved on the premise of not greatly increasing the volume of a factory building, the quick startup of a unit is realized and the safety of the unit is improved. The device is smaller in occupied space for mounting and low in cost in comparison with a conventional container type flash tank.
Description
Technical field
The utility model relates to a kind of dewatering capacity-enlarging device, particularly relates to a kind of pipe type dewatering capacity-enlarging device.
Background technique
The startup that newly-built unit puts into operation and starts or normally overhaul the back unit in labour power plant, it is hydrophobic that the main steam line that machine, stove connect can produce a large amount of pipelines.Generally speaking, this part is hydrophobic is the dewatering capacity-enlarging device that inserts turbine body.
In the mentality of designing of routine, because the factory building volume is limit, the capacity of the dewatering capacity-enlarging device that carries with the steam turbine equipment body is the hydrophobic calculation of capacity that can hold when normally moving according to unit, and when the unit cold start, the hydrophobic amount that the main steam line that machine, stove connect produces will be much larger than normal hydrophobic amount, especially in the unit of some big capacity, high parameter, because pressure medium, temperature are higher, the required volume of pipeline dewatering capacity-enlarging is bigger.
In the unit of some big capacity, high parameter, the dewatering capacity-enlarging device of turbine body can't satisfy the hydrophobic dilatation requirement of startup, insert by force as hydrophobic, if the hydrophobic amount of controlling plumbing fixtures not, high parameter is hydrophobic enter the turbine proper water drain development unit after, a large amount of steam of dilatation generation can impact turbine body equipment build-up of pressure rapidly, and security incident takes place severe patient meeting damage equipment; If the hydrophobic amount by controlling plumbing fixtures satisfies hydrophobic dilatation requirement, just must get the temperature rise speed of strict control unit, prolong the starting time of unit, just unit can't satisfy specific startup requirement like this.
The model utility content
The purpose of this utility model is to provide a kind of atmospheric type dewatering capacity-enlarging device.
The purpose of this utility model is implemented by following technological scheme, and a kind of atmospheric type dewatering capacity-enlarging device is characterized in that its main body is a steel pipe, is provided with cooling water shower interface and at least one hydrophobic collecting pipe interface on the described steel pipe walls from top to bottom.
The suitable for reading straight-through atmosphere of described pipe, the end opening of described pipe is communicated with drainage pipe.
Described steel pipe is divided into discharge of steam section, dilatation temperature descending section and hydrophobic discharge section from top to bottom, described hydrophobic caliber of discharging the caliber of section less than described dilatation temperature descending section, and the steel pipe of described dilatation temperature descending section is connected by reducer pipe with described hydrophobic steel pipe of discharging section.
Be provided with two described hydrophobic collecting pipe interfaces on the described steel pipe walls from top to bottom, be respectively hydrophobic collecting pipe interface of high pressure and the hydrophobic collecting pipe interface of middle pressure, the hydrophobic collecting pipe interface of described high pressure is arranged in the hydrophobic collecting pipe interface of described pressure top, the hydrophobic collecting pipe interface of described high pressure is connected with the hydrophobic collecting pipe of high pressure, and the hydrophobic collecting pipe interface of described middle pressure is connected with the hydrophobic collecting pipe of middle pressure.
Described cooling water shower interface is positioned at the hydrophobic collecting pipe interface of described high pressure top, and is connected with the cooling water shower.
A kind of atmospheric type dewatering capacity-enlarging of the utility model device is divided into three parts by workflow, i.e. dilatation temperature descending section, discharge of steam section, hydrophobic discharge section.
(1) dilatation temperature descending section: the steel pipe main paragraph that is connected with the hydrophobic collecting pipe of different pressures grade is the dilatation temperature descending section, and the cooling water shower that hydrophobic collecting pipe top connects is used for the flash steam cooling, condenses.
(2) discharge of steam section: the discharge of steam segment pipe leads directly to atmosphere, with the not condensing body ejectment after the dilatation to atmosphere.
(3) hydrophobic discharge section: being arranged on the bottom of atmospheric type dewatering capacity-enlarging device, is the hydrophobic exhaust port of dewatering capacity-enlarging cooling back low temperature, and the recycling system can be directly discharged or insert in draining.
Atmospheric type dewatering capacity-enlarging device operated by rotary motion should arrange by hydrophobic relatively some low level that the hydrophobic associated conduit of each branch inserts development unit by the gradient of rules requirement in the hydrophobic place of comparatively concentrating of pipeline.
Advantage of the present utility model is, pipeline dewatering capacity-enlarging tapping equipment a kind of simple in structure, easy to operate is provided.Increase under the prerequisite of factory building volume in little amplitude, solved the problem of big capacity, high parameter turbine proper water drain development unit dilatation scarce capacity, realized that unit starts fast, has improved unit safety.The device installation takes up room less, compares cheap with the development unit of conventional vessel class pattern.
