Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of radioactive waste treatment of nuclear power plants, and particularly relates to an integrated collecting device for radioactive waste liquid of a nuclear power plant. BACKGROUND

[0002] Radioactive waste liquid (hereinafter referred to as waste liquid) generated during the operation of a nuclear power plant mainly includes ground drainage water and process system equipment drainage water, wherein the former contains mechanical impurities and needs to be separated from mechanical impurities (commonly known as mud) before subsequent waste liquid treatment; the latter is relatively clean (herein, clean refers to not containing mechanical impurities) and can be sent to a subsequent waste liquid treatment unit for treatment after simple pretreatment. At present, in most radioactive waste liquid treatment systems of nuclear power plants, the classification and collection unit of waste liquid is usually classified and collected according to the radioactivity level, and less attention is paid to classification and collection according to the mechanical impurity condition. That is, most nuclear power plants do not strictly classify and collect the waste liquid of the above two sources during waste liquid collection. Since the collected waste liquid contains mechanical impurities, it has a negative impact on subsequent waste liquid treatment, and increases the difficulty and cost of waste liquid treatment.

[0057] The working principle of the application is as follows:

[0058] In the tank body 1, the baffle 2 divides the tank body 1 into two parts, and a filter screen 3 is arranged at the upper part of one part, the part with the filter screen is used for collecting waste liquid with mechanical impurities, and is called a “dirty area”, and the other part is used for collecting waste liquid without mechanical impurities, and is called a “clean area”.

[0059] After the waste liquid with mechanical impurities is collected to the mechanical impurity containing water pipe 8, it enters the dirty area of the tank body 1, the mechanical impurity containing water pipe 8 is provided with a filter 4 at one end in the tank body, and the filter 4 is located below the filter screen 3, so that the waste liquid with mechanical impurities is collected and the foreign matters possibly existing are filtered out through the filter 4, to prevent the foreign matters from entering the tank body 1 with the waste liquid. When the waste liquid with mechanical impurities enters the dirty area of the tank body 1 through the mechanical impurity containing water pipe 8, when the liquid level is higher than the upper edge of the baffle 2, the waste liquid overflows from the dirty area to the clean area of the tank body 1 through the baffle 2, the mechanical impurities are filtered by the filter screen 3 and are retained in the dirty area of the tank body 1. That is, the waste liquid is collected according to the mechanical impurities, and passive mechanical separation is realized.

[0060] After the waste liquid without mechanical impurities is collected to the mechanical impurity free water pipe 11, it enters the clean area of the tank body 1, to realize collection of the waste liquid without mechanical impurities.

[0061] When the liquid level meter 18 measures that the clean area has enough waste liquid, the valve 15 is opened, and the waste liquid transfer pump 31 is started to transfer the waste liquid in the clean area to the waste liquid treatment unit for treatment.

[0062] The mud in the dirty area is stirred by compressed air to prevent the mechanical particles from settling during transportation. When stirring, the valve 13 is opened, and the compressed air enters the dirty area of the tank 1 through the compressed air pipe 9 and the compressed air distribution pipe 10 to stir the mud in the dirty area. After sufficient stirring, the valve 13 is closed to stop the stirring operation.

[0063] When the mud in the dirty area needs to be transferred, the mud is stirred according to the above method. After the stirring is completed, the valve 16 is opened, and the mud transfer pump 20 is started to transfer the mud to the mud treatment unit for treatment.

[0064] If the waste liquid in the tank 1 cannot be transferred in time, the excess waste liquid can flow into the room pit through the overflow pipe 7.

[0065] When the equipment needs to be emptied, the waste liquid and mud in the clean area of the tank 1 are discharged to the room pit through the emptying pipe 33 and the emptying pipe 35. The bottom of the tank 1 is conical, which can ensure that the waste liquid and mud in the tank are fully discharged.

[0066] When the filter screen 3 or the filter 4 needs to be repaired, the waste liquid and mud in the tank 1 are first transferred, and the residual mud and waste liquid are discharged to the room pit through the emptying pipe 33 and the emptying pipe 35. Then, the valve 12, the valve 13 and the valve 14 are closed to isolate the water and the compressed air. After the manhole 5 or the manhole 6 is opened, the equipment is repaired.

[0067] The liquid level meter 17 realizes the liquid level monitoring of the mud in the dirty area, and the liquid level meter 18 realizes the liquid level monitoring of the waste liquid in the clean area.

[0068] The exhaust pipe 10 at the top of the tank 1 realizes the breathing exhaust of the tank 1, which ensures the pressure in the tank 1 and collects the exhaust gas of the tank 1 for treatment in the exhaust gas treatment unit.

[0069] The radioactive waste liquid classification and collection device of the application realizes the integrated classification and collection of waste liquid containing mechanical impurities and waste liquid not containing mechanical impurities, and realizes the automatic separation of mechanical impurities, which is beneficial to the operation of the subsequent waste liquid treatment unit, safe and convenient to operate, and therefore is very practical.
