BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a structural schematic diagram of the hydrogen peroxide supply metering system described in the utility model. DETAILED DESCRIPTION
[0011] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.
[0012] like Figure 1 As shown, the hydrogen peroxide supply metering system comprises: a storage tank 1 for storing hydrogen peroxide, a hydrogen peroxide inlet pipe 2 for introducing hydrogen peroxide into the storage tank 1 is arranged on the storage tank 1, a back pressure pipe 3 for introducing compressed gas into the storage tank 1 is arranged on the top of the storage tank 1, and the compressed gas can generate back pressure at the top of the inner cavity of the storage tank, so that the hydrogen peroxide can flow smoothly to the use point under the action of the back pressure, the bottom of the storage tank 1 is connected to one end of the liquid outlet pipe 4, a liquid outlet valve 5 is connected in series on the liquid outlet pipe 4, and the other end of the liquid outlet pipe 4 is connected to the vertical pipe 6 is connected in the middle part, the lower end of the vertical pipe 6 is connected with one end of the supply pipe 7, the supply pipe 7 is connected in series with a flow meter 8, the upper end of the vertical pipe 6 is connected with the lower end of the air collecting bag 9, the upper end of the air collecting bag 9 is connected with the lower end of the external discharge pipe 10, and the external discharge pipe 10 is connected in series with an exhaust valve 11; an upright return air pipe 12 is also provided, the lower end of the return air pipe 12 is connected with the liquid outlet pipe 4, and the connecting point is located between the liquid outlet valve 5 and the storage tank 1, and the upper end of the return air pipe 12 is connected with the top of the storage tank 1.
[0013] In this embodiment, a flow limiting mechanism is also connected in series to the outer pipe 10, and the flow limiting mechanism is located below the exhaust valve 11. The structure of the flow limiting mechanism includes: a mounting tube 13 connected in series to the outer pipe 10, the inner diameter of the mounting tube 13 is larger than the outer diameter of the outer pipe 10, a flow limiting plate 14 is fixed in the mounting tube 13, a flow limiting hole 15 is arranged in the middle of the flow limiting plate 14, the aperture of the flow limiting hole 15 is smaller than the inner diameter of the outer pipe 10, and the outer ring side wall of the flow limiting plate 14 is sealed and fixed to the inner wall of the mounting tube 13, so that the flow limiting plate 14 can limit the gas discharged from the outer pipe 10 through the flow limiting hole 15 thereon.
[0014] The outlet of the hydrogen peroxide inlet pipe 2 is located at the bottom of the inner cavity of the storage tank 1. This arrangement is to avoid the impact during the inlet, which may cause the decomposition of the hydrogen peroxide, thereby reducing the bubbles in the hydrogen peroxide. The bottom of the storage tank 1 is connected to a discharge pipe 16, and a discharge valve 17 is connected in series to the discharge pipe 16.
[0015] During operation, the hydrogen peroxide in the storage tank 1 will decompose and generate bubbles over time. These bubbles will enter the liquid outlet pipe 4 along with the flow of hydrogen peroxide. When reaching the position of the return air pipe 12, the bubbles in the hydrogen peroxide will float up into the return air pipe 12 due to their low density, and finally return to the storage tank 1. After the hydrogen peroxide enters the vertical pipe 6, the bubbles in the hydrogen peroxide will float up into the gas collecting bag 9. After being collected by the return air pipe 12 and the gas collecting bag 9, the bubbles in the hydrogen peroxide will be greatly reduced. Therefore, when the hydrogen peroxide flows through the flow meter, the detection value of the flow meter will be relatively stable, so that the system can stably and accurately supply hydrogen peroxide.
[0016] After a period of operation, when a certain amount of gas is collected in the gas collection bag 9, the exhaust valve 11 needs to be opened to discharge the collected gas so as to continue collecting gas. Because a limiting flow plate 14 is arranged between the gas collection bag 9 and the exhaust valve 11, the limiting flow plate 14 can limit the flow of the gas discharged from the external discharge pipe 10 through the limiting hole 15 thereon, thereby controlling the speed of gas discharge, and will not cause the pressure in the vertical pipe 6 to drop rapidly, causing a large fluctuation in the flow rate.
