Embodiment 1

[0024] Embodiment one sees Figure 1-3 As shown, in this embodiment, the motor 1 is a motor with shafts at both ends, which can be purchased from the market. One end of the motor shaft 18 in the motor 1 is coaxially connected with the water pump shaft 21 in the pressurized water pump 2 , The other end is coaxially connected with the air releaser rotating shaft 10 in the turbine air releaser 3 .

[0025] see figure 1 As shown, in general, the motor shaft 18 in the motor 1 is coaxially connected with the air releaser shaft 10 in the turbine air releaser 3 through a coupling 20, which is a direct connection at this time. see Figure 4 As shown, when it is difficult to match the design of the speed of the turbine degasser 3 and the pressurized water pump 2, it can be selected Figure 4 The implementation of the scheme is to match the speed of the turbine air releaser 3 and the pressurized water pump 2 through the transmission 11, that is, the air releaser shaft 10 is coaxially ...

Embodiment 3

[0031] Embodiment three see Figure 6 , the difference from Embodiment 1 is that the motor 1 is a motor with a shaft at one end, and the pressurized water pump 2 is a water pump with a shaft at both ends (this kind of water pump can be customized from the factory), and the water pump in the pressurized water pump 2 One end of the rotating shaft 21 is coaxially connected with the motor rotating shaft 18 in the motor 1 , and the other end is stretched out from the water pump inlet 4 of the pressurized water pump 2 and is coaxially connected with the air releaser rotating shaft 10 in the turbine air releaser 3 . Under normal circumstances, the deaerator rotating shaft 10 can be coaxially connected with the water pump rotating shaft 21 through a coupling 20, a flange or a gear transmission mechanism. The degasser rotating shaft 10 can also be coaxially connected with the water pump rotating shaft 21 through a transmission.

Embodiment 4

[0032] Embodiment four see Figure 7 , the difference from Embodiment 1 is that the motor 1 is a motor with a shaft at one end, and the turbine air releaser 3 is an air releaser with a shaft at both ends (this turbine air releaser can be customized from the factory ), one end of the deaerator shaft 10 in the turbine deaerator 3 is coaxially connected with the motor shaft 18 in the motor 1, and the other end is coaxially connected with the water pump shaft 21 in the pressurized water pump 2. Generally, the degasser rotating shaft 10 can be coaxially connected with the motor rotating shaft 18 and the water pump rotating shaft 21 through a coupling, a flange or a gear transmission mechanism.

[0033] In a word, in each embodiment, the degasser rotating shaft 10, the motor rotating shaft 18 and the water pump rotating shaft 21 can be coaxially connected together through a coupling 20, a flange or a gear transmission mechanism, and they can also be cast as one. of an axis.

Abstract

The invention discloses a gas dissolving and releasing device with pressurization water pump and turbine air releaser being coaxial. The gas dissolving and releasing device comprises a motor, a pressurization water pump, a turbine air releaser, a high-pressure water pipe, an air dissolver, an air dissolving tank and an air dissolving water pipe; a motor rotation shaft in the motor is in driving connection with a water pump rotation shaft in the pressurization water pump; a water outlet end of the pressurization water pump is communicated with the air dissolver in the air dissolving tank through the high-pressure water pipe; and an air outlet of the air dissolving tank is connected with the turbine air releaser through the air dissolving water pipe. The pressurization water pump and turbine air releaser coaxial dissolving and releasing device is characterized in that: an air releaser rotation shaft in the turbine air releaser, the motor rotation shaft in the motor and the water pump rotation shaft in the pressurization water pump are coaxially and rotatably connected; and the set rotation speed of the turbine releaser is higher than the rotation speed of the motor under a load-freecondition. Compared with the prior art, the device is capable of saving abundant electric energy, saving two conversion processes of converting mechanical energy into electric energy through the motor and then converting electric energy into mechanical energy through the motor, saving the cost and increasing the efficiency.

Description

technical field [0001] The invention relates to a dissolved air-release device used in a pressurized dissolved air flotation process. Background technique [0002] Air flotation water purification is an internationally recognized excellent water treatment technology that can efficiently separate solid-liquid and liquid-liquid. It can be used not only for domestic drinking water and industrial water treatment, but also for oil refining, chemical industry, and papermaking. , tanning, steel, food, medicine, sludge concentration, landfill leachate treatment, separation of heavy metal ions and other industrial wastewater and urban domestic sewage treatment technologies. There are many classifications of air flotation water purification process, among which the most widely used is the pressurized dissolved air flotation process, which includes dissolved air, degassing, adhesion, and separation. The process of gas dissolution and gas release can be simply summarized as pressurize...
