Abstract

The invention relates to a power system and m. used to heat and deaerate water in thermal power plants. The invention makes it possible to increase the cost-effectiveness and deepen deaeration at high temperatures of deaerated water. The overflow and bubble plates (T) 4, 5 are adjoined by vertically mounted partitions 8, dividing the space between these plates into separate compartments 9. Sectioning and vertical partitions 7 and 8 form channels 10 for the passage of steam, and the compartments 9 are connected to each other by horizontal pipes 11. Deaerated water from T 4 enters the initial part of T 5. Steam is supplied to the bottom of the column and flows through channels 10 under T 5 repeatedly passing through a layer of water. The deaerated water passes along T 5 from the compartment to compartment 9 through nozzles 11 and then through the overflow device 15 is diverted to the storage tank. 1 il. $ 12 J CO 4 SL

shaving is related to the heat source

the flow rate is defined as the minimum and plate distance 5. flow cut with

the heat engineering and industrial heat engineering, in particular, to thermal deaerators used in heating and thermal deaeration of water, can be used at thermal power plants.

The aim of the invention is to increase the efficiency and deepen deaeration at high temperatures deaerated water.

The drawing shows the proposed deaerator, a general view.

5, is reduced due to a reduction in steam consumption to the deaerator in general. At a certain load, the steam flow rate to the deaerator becomes less than the minimum required flow rate that must be passed through a bubble plate 5 to ensure quality deaeration, even without condensation of steam in the water layer on the bubble tank 5. In the proposed invention, this steam stream repeatedly passes through the layer water that ultimately provides sufficient access

The thermal deaerator contains the contact time required for 1 column 2 rolled on the storage tank 1, with distribution box 3 placed in it, overflow 4, bubble 5 plates and tray 6. The bubble plate is equipped with 20 partitioning walls 7, with - milling; they to the bottom of the pallet 6. Overflow 4 and bubbling 5 plates are adjacent vertically mounted partitions 8, dividing the space between these plates into separate compartments 9. Sectioning partitions 7 and vertical partitions 8 Steam channels 10 are connected, and compartments 9 are interconnected by horizontal pipes 11 placed in the water space above the bubble plate 5. Columns 2, 12, 13, and 14 are connected to supply water, steam and steam extraction plates 5 installed drain device 15.

The thermal desolver works as follows.

The water to be deaerated through pipes 12 enters the water distribution plate 3, from where it is discharged to the perforated plate 4 and then to the ngchalny section of the bubbling plate 5. Steam is supplied to the lower part of the column 2 through the nozzle 13, through the channels 10 it flows under the bubbled plate 5 and repeatedly pass through a layer of water, it condenses onto the jets. The deaerated water passes along the bubble plate 5 from the compartment into compartment 9 through nozzles 11 and then through the overflow device 15 is diverted into storage tank 1.

With an increase in the temperature of the incoming water (when the temperature of the pressure is small) and its low consumption, the specific steam consumption is necessary, Shch1 effective water treatment for. bubbling taak deaeration. ,

With a low temperature head and high water flow rates, it is necessary to pass through the bubble plate 5 a significantly larger (5–10 times) steam flow rate than is required by the heat balance. The high consumption of steam due to the impossibility of its complete condensation due to the low heating is diverted with evaporation, which increases the loss of body. In the present invention, when the steam flow repeatedly passes through the water of the water, all the steam manages to

30, which eliminates heat loss through evaporation.

Thus, the application of this technical solution allows to increase the efficiency and deepen the deaera

35 at high temperatures of deaerated water.

Claims (1)

Invention Formula 40 A thermal deaerator containing a column mounted on the tank-accumulator with river-mounted, water distribution overflow and a bubble plate and a tray 45, wherein the bubble plate is provided with partitioned baffles located under it, which is characterized by the fact that, in order to improve the economy and deepen deaeration of the high temperatures of the water to be deaerated, the column is additionally equipped with horizontally installed branch pipes and adjacent to them overflow and bubble plates to vertical gg partitions dividing the space between these plates into compartments, with the partitioning partitions strapping to the bottom of the pallet and forming septal channels music 5, is reduced due to a reduction in steam consumption to the deaerator in general. At a certain load, the steam flow rate to the deaerator becomes less than the minimum required flow rate that must be passed through the bubble plate 5 to ensure quality deaeration, even without condensation of steam in the water layer on the bubble plate 5. In the present invention, this steam flow repeatedly passes through a layer of water, which ultimately ensures long-term availability contact time required for ka fair deaeration. , With a low temperature head and high water flow rates, it is necessary to pass through the bubble plate 5 a significantly larger (5–10 times) steam flow rate than is required by the heat balance. The high consumption of steam due to the impossibility of its complete condensation due to low heating is removed with evaporation, which increases heat loss. In the present invention, by repeatedly passing the steam flow through the Ctoya water, all the steam manages to condense, which eliminates heat loss with evaporation. Thus, the application of this technical solution allows to increase the efficiency and deepen deaeration at high temperatures of deaerated water. Invention Formula A thermal deaerator containing a column mounted on the tank-accumulator with river-mounted, water distribution overflow and a bubble plate and a tray, the bubble plate is provided with sectional partitions located under it, characterized in that, in order to increase efficiency and deepen deaeration at high temperatures of deaerated water, the column is additionally equipped with horizontally installed nozzles and adjacent to them overflow and bubbling plates with vertical partitions dividing the space between these plates into compartments, with the partitioning partitions adjoining the bottom of the pallet and forming Vertical, partitions channels 31345007 for the passage of steam, and the compartments are communicated in the water space above the bubbling between each other by branch pipes placed on the plate.
