Technical Field
[0001] This utility model belongs to the field of coal mine underground water treatment technology, specifically relating to a modular, power-free mine reverse osmosis water treatment equipment. Background Technology
[0002] Purification devices for emulsion mixing water in underground hydraulic systems of coal mines (such as reverse osmosis devices) have long faced two major technical bottlenecks: First, the problem of power supply dependence. The detection instruments and dosing pumps of traditional devices need to be connected to external power sources, which not only increases the difficulty of underground explosion-proof design, but is also subject to power supply limitations. Second, the problem of maintenance and adaptability. The integrated structure is difficult to transport, and there is a lack of full-process sensing and monitoring, resulting in low efficiency in fault diagnosis.
[0003] In existing technologies, some devices attempt to use electric dosing pumps or external power supplies. While these can meet basic functions, they pose safety hazards (such as electrical explosion risks) in the complex downhole environment, and lack the flexibility of relying on power supply. Therefore, there is an urgent need for a reverse osmosis device that is completely independent of power supply, has flexible configuration, and is adaptable to the downhole environment. Utility Model Content
[0004] The purpose of this invention is to provide a modular, power-free reverse osmosis water treatment device for mining, thereby solving the aforementioned technical problems in the existing technology.
[0005] Therefore, the technical solution provided by this utility model is as follows:
[0006] A modular, power-free mine reverse osmosis water treatment device includes a primary filtration unit, a reverse osmosis unit, and a PLC controller. The primary filtration unit and the reverse osmosis unit are detachably connected by a flexible hose, and both the primary filtration unit and the reverse osmosis unit are equipped with a fully enclosed skid-mounted housing.
[0007] The water flow pipeline of the primary filtration unit and / or reverse osmosis unit is equipped with a hydraulic power generation device. The inlet of the reverse osmosis unit is connected to a pneumatic dosing pump, the outlet of the reverse osmosis unit is connected to a pure water tank, and the other end of the pneumatic dosing pump is connected to a chemical tank through a pipeline.
[0008] The inlet and outlet of the primary filtration unit are respectively equipped with an inlet pressure sensor and an outlet pressure sensor. The inlet and outlet of the reverse osmosis unit are respectively equipped with an inlet conductivity sensor and an outlet conductivity sensor. The hydraulic power generation device is used to power the inlet pressure sensor, outlet pressure sensor, inlet conductivity sensor, outlet conductivity sensor, and PLC controller. The inlet pressure sensor, outlet pressure sensor, inlet conductivity sensor, and outlet conductivity sensor are all electrically connected to the PLC controller.
[0009] Furthermore, the primary filtration unit includes a pressure reducing valve, a hand brush filter, a fiber filter canister, and at least two precision filters connected in series along the water flow direction.
[0010] Furthermore, the reverse osmosis unit includes multiple single-membrane housings, each of which contains a reverse osmosis membrane. The inlet of the reverse osmosis unit is equipped with a hydraulic control valve, and the pure water tank is equipped with a level float valve. The hydraulic control valve and the level float valve are linked together.
[0011] Furthermore, the outlet pipe of the primary filtration unit is connected to multiple branch interfaces, which can be connected to the inlet of multiple reverse osmosis units one by one.
[0012] Furthermore, the primary filtration unit also includes an inlet flow sensor, an outlet flow sensor, a pressure reducing sensor, a pressure sensor after the hand brush filter, a pressure sensor after the fiber filter, a pressure sensor after the precision filter, an inlet conductivity sensor, an inlet chemical oxygen demand sensor, an inlet pH sensor, an outlet conductivity sensor, an outlet chemical oxygen demand sensor, and an outlet pH sensor. All of the above sensors are electrically connected to the PLC controller.
[0013] Furthermore, the reverse osmosis unit also includes an influent chemical oxygen demand sensor, an influent pH sensor, an effluent chemical oxygen demand sensor, an effluent pH sensor, a pressure sensor after the dosing pump, a chemical solution flow sensor, and a chemical tank level sensor.
[0014] Furthermore, the precision filter has a filtration accuracy of 3~5μm and a water production capacity of 35~40 tons / hour for the primary filtration unit.
[0015] Furthermore, the hydraulic power generation device is a turbine-type hydroelectric generator, integrated into the outlet pipe of the primary filtration unit or the inlet pipe of the reverse osmosis unit.
[0016] The beneficial effects of this utility model are as follows:
[0017] This modular, power-free reverse osmosis water treatment equipment for mines utilizes underground static pressure water to drive a hydraulic generator to power the PLC controller and all sensors. It also employs underground air pressure to drive a pneumatic dosing pump to add scale inhibitors and other chemicals, completely eliminating reliance on a power source. Both the primary filtration unit and the reverse osmosis unit feature fully enclosed skid-mounted housings, adaptable to the underground environment.
