Description

The utility model relates to the field of water treatment and can be used at thermal power plants.

A known analogue is a water treatment plant for makeup water of a thermal power plant, containing makeup water deaerator with a source water pipe connected to it, supply and outlet gas pipelines, a tank - a deaerated water accumulator connected to a return network water pipeline (see Patent No. 2537656). This analogue is adopted as a prototype.

The disadvantage of the analogue and the prototype is the reduced quality of water treatment by the water treatment plant of the thermal power plant, since the gas after the reducing installation of the thermal power plant has a very low (often negative) temperature, which significantly reduces the quality of deaeration of makeup water.

The technical problem that the utility model addresses is the development of a water treatment plant for make-up water of a thermal power plant.

The technical result achieved by the utility model is to increase the quality of deaeration of make-up water by increasing the temperature of the gas in front of the deaerator.

To achieve this technical result, a water treatment plant of a thermal electric power plant has been proposed, comprising a make-up water deaerator, with a source water pipe connected to it, supply and exhaust gas pipelines, a battery-deaerated water tank connected to a return network water pipe.

The peculiarity is that a gas heater is installed on the feed gas line of the make-up water deaerator, connected by a heating medium pipeline to the return network water pipe between the booster network pump and network heaters, and a chilled heating medium pipeline from the gas heater is connected to the return network water pipe in front of the booster network the pump.

Next, we consider the information confirming the possibility of implementing a utility model with obtaining the desired technical result.

The drawing shows a schematic diagram of a water treatment plant for makeup water of a thermal power plant. The installation comprises a source water pipe 1 connected to a make-up water deaerator 2 with a tank - a deaerated water accumulator 3, connected by a pipe 4 to a return network water pipe 5, which includes a booster network pump 6, network heaters 7 connected to a constant pressure sampling of a steam turbine 8. A supply gas pipe 9 and a discharge gas pipe 10 connected to the burners of the steam boiler 11 are connected to the feed water deaerator 2, and a gas heater 12 is connected to the gas supply pipe 9 the heating medium pipeline to the return network water pipe 5 between the network heaters 7 and the booster network pump 6, and the cooled heating medium pipeline from the gas heater 12 is connected to the return network water pipe 5 in front of the booster network pump 6.

Water treatment plant makeup water thermal power station operates as follows. Water through the pipeline 1 of the source water is supplied to the deaerator 2 of makeup water. The natural gas used as the stripping agent is sent through the supply gas line 9 to the make-up water deaerator 2. The gas in the supply gas pipe 9 with the help of a gas heater 12 is heated to the required temperature of 35-50 ° C with reverse network water. Natural gas from the deaerator 2 of make-up water is released through the exhaust gas line 10 to the burners of the steam boiler 11. The deaerated water is discharged from the deaerator 2 of the make-up water into the storage tank 3 of the deaerated water, and then through the pipe 4 it is fed into the return pipe 5 mains water in front of the booster mains pump 6.

Thus, the new interconnection of elements makes it possible to increase the efficiency of the water treatment plant of the make-up water of the thermal power station.
