Description

[Technical field]

[0001] The present invention relates to the technical field of removing mussels in the pipelines of hydroelectric power plants, and in particular to a sterilization apparatus and a hydroelectric power plant system. [Background technology]

[0002] Golden mussels are Asian freshwater mussels, scientifically known as Limnoperna maritima, and are found mainly in rivers, lakes and dams in the Yangtze, Yellow, Pearl, Huai and Hai river basins. Golden mussels have extremely strong reproductive power, great harm and strong adhesive power, and their high density adhesion and reproduction can cause serious blockages in the water pipelines of hydroelectric power station units, affecting the safe and stable operation of hydroelectric power station units. The invasion of golden mussels forced the Itaipu Hydropower Station to carry out inspections and repairs and to suspend production.

[0003] Regularly removing mussels in the water pipelines of hydroelectric power plants is an important part of ensuring the safe and stable operation of hydroelectric power plant units. The traditional method of removing mussels usually involves mechanical manual removal, that is, first draining the water accumulated in the water pipelines to allow the mussels to naturally dehydrate and die, and then removing and scrubbing them off manually or with auxiliary machines (such as pressurized water guns). This removal method is labor-intensive, costly, time-consuming, and affects the normal operation of hydroelectric power plants. Summary of the Invention [Problem to be solved by the invention]

[0004] In view of the above, the present invention provides a sterilization apparatus and hydroelectric power plant system to solve the problems of high labor intensity, high cost and time-consuming work of removing golden mussels in the pipelines of conventional hydroelectric power plants. [Means for solving the problem]

[0005] In a first aspect, the present invention provides a sterilization apparatus for removing golden mussels in a water pipeline of a hydroelectric power plant, the sterilization apparatus comprising: a bacterial liquid dissolution tank suitable for placing a sterilizing liquid therein; a transport pipeline having one end connected to the bacterial liquid dissolution tank and the other end connected to the water pipeline of the hydroelectric power plant; and a pressure pump provided in the transport pipeline.

[0006] The sterilization device of the present invention uses a pressure pump to drive the sterilizing liquid from the bacteria liquid dissolution tank to the transport pipeline, and then through the transport pipeline into the water pipeline of the hydroelectric power plant. The sterilizing liquid destroys the golden mussels attached to the water pipeline of the hydroelectric power plant, thereby achieving the purpose of cleaning the water pipeline of the hydroelectric power plant. Compared with the traditional mechanical manual removal method, the removal method of the present invention is more efficient, saves labor and time, and ensures the normal operation of the hydroelectric power plant.

[0007] In an alternative embodiment, the sterilization apparatus further includes a compound storage tank connected to the bacterial liquid dissolving tank, the compound storage tank can store a certain amount of compound, and while injecting water into the bacterial liquid dissolving tank, the compound storage tank supplies the compound to the bacterial liquid dissolving tank, and the compound can be dissolved in water to form a sterilization liquid.

[0008] In an alternative embodiment, the compound storage tank is located above the bacterial liquid lysis tank, and the compound in the compound storage tank can fall into the bacterial liquid lysis tank by gravity.

[0009] In an optional embodiment, the sterilization apparatus further includes a control valve disposed in the transport pipeline. When the hydroelectric power station is operating normally, the control valve is closed to cut off the transport pipeline, at which time the sterilizing liquid does not flow, and when the water pipeline of the hydroelectric power station needs to be disinfected and sterilized, the control valve is opened to connect the transport pipeline, at which time the sterilizing liquid flows through the transport pipeline into the water pipeline of the hydroelectric power station, thereby realizing the removal of golden mussels in the water pipeline of the hydroelectric power station.

[0010] In an alternative embodiment, the sterilization apparatus further includes a motor connected to the pressure pump, the motor driving and operating the pressure pump to ensure normal operation of the entire sterilization apparatus.

[0011] In an alternative embodiment, the sterilization apparatus further includes a control unit, which is connected to the motor and the control valve, so as to control the motor to be turned on and the control valve to be opened at a preset time. When the water pipes of the hydroelectric power station need to be cleaned, the control unit can automatically control the motor to be turned on and the control valve to be opened, thereby automatically and periodically removing the golden mussels in the water pipes of the hydroelectric power station and realizing efficient cleaning.

[0012] In a second aspect, the present invention provides a hydroelectric power plant system, comprising: a water pipeline of a hydroelectric power plant; and a sterilization apparatus of the present invention, wherein the other end of the transport pipeline of the sterilization apparatus is connected to the water pipeline of the hydroelectric power plant.

[0013] In an optional embodiment, the hydroelectric power station system further includes a sterile branch pipeline, one end of which is connected to the water pipeline of the hydroelectric power station, and the other end of which is connected to the other end of the transport pipeline. The added sterile branch pipeline does not affect the normal operation of the hydroelectric power station, and a sterilization device can also be connected when the water pipeline of the hydroelectric power station needs to be cleaned, thereby achieving the disinfection and sterilization effect on the golden mussels in the water pipeline of the hydroelectric power station.

[0016] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments that a person skilled in the art can obtain without making creative efforts belong to the protection scope of the present invention.

[0017] Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

[0018] According to an embodiment of the present invention, in one aspect, a sterilization apparatus is provided, comprising a bacteria liquid dissolving tank 1, a transport pipeline 2, and a pressure pump 3, wherein the bacteria liquid dissolving tank 1 is suitable for placing chlorine water therein, one end of the transport pipeline 2 is connected to the bacteria liquid dissolving tank 1, the other end of the transport pipeline 2 is suitable for connecting to a water pipeline of a hydroelectric power plant, and the pressure pump 3 is provided in the transport pipeline 2.

[0019] The sterilization device of the present invention uses a pressure pump 3 to drive the sterilizing liquid from the bacteria liquid dissolution tank 1 to the transport pipeline 2, and then through the transport pipeline 2 into the water pipeline of the hydroelectric power plant. The sterilizing liquid eliminates the golden mussels attached to the water pipeline of the hydroelectric power plant, thereby achieving the purpose of cleaning the water pipeline of the hydroelectric power plant. Compared with the traditional mechanical manual removal method, the removal method of the present invention is more efficient, saves labor and time, and ensures the normal operation of the hydroelectric power plant.

[0020] The sterilizing liquid may be, specifically, a solution capable of exerting a sterilizing effect on the golden mussel, such as chlorine water, ozone water, etc. In this embodiment, the sterilizing liquid is chlorine water.

[0021] The bacteria liquid dissolving tank 1 is for storing a certain volume of sterilizing liquid and providing the sterilizing liquid in real time for cleaning water pipelines of hydroelectric power plants.

[0022] Since the sterilizing liquid usually has an irritating odor and is easily volatilized, it is preferable that the bacterial liquid lysis tank 1 be provided as a closed tank in order to reduce the impact on the environment due to the volatilization of the sterilizing liquid.

[0023] The transport pipeline 2 may be a metal pipeline or a flexible pipeline made of plastic, and in this embodiment, the transport pipeline 2 is provided as a metal pipeline to extend its service life.

[0024] Specifically, a through hole is opened in the tank wall of the bacterial liquid dissolution tank 1, one end of the transport pipeline 2 is inserted into the through hole to communicate with the inside of the bacterial liquid dissolution tank 1, and the outer wall of the transport pipeline 2 and the inner wall of the through hole are sealed to prevent leakage of the sterilizing liquid.

[0025] The pressure pump 3 is used to increase the power for the overall flow of the sterilizing liquid, and is a well-known element in this field, so a duplicated description will be omitted here.

[0026] In addition to the above-mentioned configuration, the sterilization apparatus of this embodiment further includes a compound storage tank 4 connected to the bacterial liquid dissolving tank 1. The compound storage tank 4 can store a certain amount of compound, and while injecting water into the bacterial liquid dissolving tank 1, the compound storage tank 4 supplies the compound to the bacterial liquid dissolving tank 1, and the compound can be dissolved in water to form a sterilization liquid.

[0027] Specifically, the substances such as chlorine sheet, chlorine gas or ozone that can be stored in the compound storage tank 4 are specifically selected according to the sterilization needs.

[0028] Similarly, the compound storage tank 4 is preferably provided as a sealed tank in order to ensure the performance of the compound while reducing the impact on the environment due to volatilization of the compound.

[0029] The compound storage tank 4 and the bacterial liquid dissolution tank 1 can be connected via piping. The compound storage tank 4 is located above the bacterial liquid dissolution tank 1, and the compounds in the compound storage tank 4 can fall into the bacterial liquid dissolution tank 1 by gravity.

[0030] In addition, the sterilization apparatus further includes a control valve 5 installed in the transport pipeline 2. The control valve 5 can control the opening and closing of the transport pipeline 2. When the hydroelectric power station is operating normally, the control valve 5 is closed to cut off the transport pipeline 2, at which time the sterilizing liquid does not flow, and when the water pipeline of the hydroelectric power station needs to be disinfected and sterilized, the control valve 5 is opened to connect the transport pipeline 2, at which time the sterilizing liquid flows through the transport pipeline 2 into the water pipeline of the hydroelectric power station, thereby realizing the removal of golden mussels in the water pipeline of the hydroelectric power station.

[0031] In this embodiment, the sterilization apparatus further includes a motor 6 connected to the pressure pump 3. The motor 6 drives the pressure pump 3 to operate, so as to ensure the normal use of the entire sterilization apparatus.

[0032] As will be understood, the types and models of the control valve 5 and the motor 6 can be selected from various options in the prior art according to need, and therefore, the present embodiment will not be described in detail.

[0033] In an optional embodiment, the sterilization apparatus further includes a control unit, which is connected to the motor 6 and the control valve 5, so as to control the motor 6 to be turned on and the control valve 5 to be opened at a preset time. When the water pipes of the hydroelectric power station need to be cleaned, the control unit can automatically control the motor 6 to be turned on and the control valve 5 to be opened, thereby automatically and periodically removing the golden mussels in the water pipes of the hydroelectric power station and realizing efficient cleaning.

[0034] Specifically, a signal connection or an electrical connection can be used between the control unit and the motor 6 and the control valve 5, and the on / off of the motor 6 and the opening / closing of the control valve 5 are controlled by the signal from the control unit, which is automatic and efficient.

[0035] Incidentally, the signal transmission and transmission of the control unit is a conventional technique, and therefore, a duplicated explanation will be omitted in this embodiment.

[0036] In order to facilitate understanding of the sterilization apparatus of this embodiment, its usage process will be described below.

[0037] When it is necessary to disinfect and sterilize the water pipelines of a hydroelectric power plant, water is injected into the bacteria liquid dissolution tank 1, and the compounds in the compound storage tank 4 are added to the bacteria liquid dissolution tank 1 and dissolved in the water to form a sterilizing liquid. The control unit automatically controls the turning on of the motor 6 and the opening of the control valve 5, the control valve 5 is opened to connect the transport pipeline 2, the motor 6 drives the pressure pump 3 to operate, and the pressure pump 3 drives the sterilizing liquid to flow from the bacteria liquid dissolution tank 1 to the transport pipeline 2, pass through the transport pipeline 2, flow through the sterilizing branch pipeline and enter the water pipelines of the hydroelectric power plant, and the golden mussels attached to the water pipelines of the hydroelectric power plant are destroyed by the sterilizing liquid.

[0038] According to an embodiment of the present invention, in another aspect, there is provided a hydroelectric power plant system including a water pipeline of a hydroelectric power plant and a sterilization apparatus of the present invention, wherein the other end of the transport pipeline 2 of the sterilization apparatus is connected to the water pipeline of the hydroelectric power plant.

[0039] The hydroelectric power station system of the present invention is equipped with a sterilization device. When the water pipelines of the hydroelectric power station need to be disinfected and sterilized, the sterilization device can be turned on to introduce sterilizing liquid into the water pipelines of the hydroelectric power station, thereby achieving disinfection and sterilization of the golden mussels, which is very convenient and efficient.

[0040] In an optional embodiment, the hydroelectric power station system further includes a sterile branch pipeline, one end of which is connected to the water pipeline of the hydroelectric power station, and the other end of which is connected to the other end of the transport pipeline 2. The added sterile branch pipeline does not affect the normal operation of the hydroelectric power station, and a sterilization device can be connected when the water pipeline of the hydroelectric power station needs to be cleaned, thereby realizing the disinfection and sterilization effect on the golden mussels in the water pipeline of the hydroelectric power station.
