SU992430A1 - Dearator - Google Patents

Description

The invention relates to a power system and can be used for the deaeration of feedwater for boiler units of thermal and nuclear power plants (thermal power plants and nuclear power plants), as well as for the deaeration of heat supply network water.

A deaerator is known, comprising a housing with jet and bubbling plates and a compartment separated in the housing for supplying a heating medium.

The disadvantage of this deaerator is the countercurrent movement of liquid and gas in it, which limits the speed of the deaeration process, degrades the flow hydrodynamics and leads to an increase in the size of the device.

Also known is a deaerator containing cylindrical columns mounted on an accumulator tank, each of which has a water inlet / water collector nozzle, a heating media distributor, and a waste water nozzle 2.

The disadvantages of the known deaerator are the low quality of the deaeration and the complex construction. .

The purpose of the invention is to improve the quality of deaeration and simplify the design of the deaerator.

(54) DEAERATOR

The goal is achieved by the fact that a deaerator containing cylindrical columns mounted on an accumulator tank, X1 of which has a water inlet, a water collector; a spreader distributor and a vapor outlet pipe, equipped with a separating compartment connected to the columns and formed by the established way

to the last vertical and partitions with a horizontal edge, on which is installed the pattern of removal of steam.

In addition, the distributor is manufactured in the form of a pipe passed through a collector, equipped with a nozzle at the outlet end, and a row of discs with holes in the center located below the collar along the axis of the column,

20 and the hole in the upper disk is smaller than the outlet of the nozzle. Nozzle, and in each subsequent disk height less than the previous one ...

The disks are made in the form of v} vcho ah cones, with the smaller base facing upwards, and below the lower disk an additional conical divider is installed, and the image of the conic

30 owls have angles of inclination

c in the direction of movement of the environment.

The drawing schematically shows deaeratr, longitudinal section.

The deaerator contains cylindrical columns 2 installed on the accumulator tank 1, each of which has a water inlet nozzle 3, a water collector 4, a heating dispenser and a nozzle 5 for evacuating the vapor. The deaerator is also provided with a separation compartment 6 connected to columns 2 and formed by vertical partitions 7 with a horizontal cover 8, on which is installed a branch pipe 5 for evacuation of steam. The distributor of the heating medium is made in the form of a pipe 9 passed through a collector 4, provided at the outlet end with a nozzle nozzle 10, and placed below the nozzle along the axis of the column 2 a row of disks 11 with holes (not shown in the center, the hole in the upper disk 11 is smaller than the output the nozzle holes 10, and in each subsequent disk height is less than the previous one. The disks 11 are made in the form of truncated cones, with the smaller base facing up, and below the lower disk 11 there is additionally installed a conical divider 12, Suitable angles of the cones are iaklon umenshayuschies in the direction of movement of the heating medium. Also, the injector 13 comprises a deaerator.

The deaerator works as follows.

The water for deaeration enters through the nozzle 3 into the collector 4, and then to the nozzles 13, through which it is sawn into the deaeration zone. Heating medium is supplied to the distributor pipe 9 and further through the nozzle nozzle 10 is distributed over the entire height of the column using discs 11.

Steam and non-condensate (mdiez gases flow into the separation compartment 6, where there is a separation of water droplets from gas and steam, which through the pipe 5 is discharged from the separation ejection b.

The deaerator provides high quality of geoeration at low capital and operating costs. Its use allows you to increase

water treatment efficiency, and the use of both steam and deaerated water as a Greek medium leads to a highly unified apparatus ..
