Description

Technical Field

[0001] The utility model relates to a pH value regulating device, in particular to a carbon dioxide dosing device. Background Art

[0002] A carbon dioxide dosing device is a device used to add carbon dioxide into water to lower the pH value of the water and is widely used in water plants.

[0003] When carbon dioxide continuously dissolves in water to generate carbonic acid, the carbonic acid also needs to decompose to "make up" for the lost carbon dioxide. By adjusting the supply of carbon dioxide gas, the carbon dioxide lost in the reaction is made up, and the balance in the reaction is controlled, thereby achieving the adjustment of the pH value. However, when adding carbon dioxide, the relevant carbon dioxide dosing device is prone to cause a small contact area between gaseous carbon dioxide and water, resulting in poor reaction effect between carbon dioxide and water, and further resulting in poor dosing effect of the relevant carbon dioxide dosing device.

DETAILED DESCRIPTION

[0035] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figure 1 This embodiment provides a carbon dioxide dosing device, including: a container 1; a plurality of aeration plates 2 located in the container 1; a water supply component 3 connected to one end of the container 1; a pressure reducing component 4 connected to the plurality of aeration plates 2; and a mixing component 5 connected to the other end of the container 1.

[0038] Specifically, during operation, first, water enters the container 1 through the water delivery component 3. At the same time, liquid carbon dioxide is converted into gaseous carbon dioxide through the pressure reducing component 4. The gaseous carbon dioxide enters the container 1 through several aeration plates 2, so that the gaseous carbon dioxide and water are initially mixed. Then, the gaseous carbon dioxide and water simultaneously enter the mixing component 5 for full mixing. Finally, the mixture of gaseous carbon dioxide and water is added to the relevant water body to reduce the pH value of the relevant water body.

[0039] The container 1 is used to accommodate a number of aeration plates 2, etc., and to allow the gaseous carbon dioxide and water to be preliminarily mixed; the number of aeration plates 2 is used to transfer the gaseous carbon dioxide to the water in the container 1. Compared with the relevant ventilation pipes, the number of aeration plates 2 facilitates a large contact area between the gaseous carbon dioxide and water, thereby improving the reaction effect of carbon dioxide and water, and further improving the addition effect of the carbon dioxide dosing device of the present application. The number of aeration plates 2 is not limited, and can be three, four, etc., preferably four; the water delivery component 3 is used to transfer water to the container 1; the pressure reducing component 4 is used to convert the liquid carbon dioxide in the relevant cylinder into gaseous carbon dioxide, and then transfer it to the number of aeration plates 2. It should be noted that, in order to facilitate storage and transportation, carbon dioxide is generally stored in liquid form in the relevant cylinder; the mixing component 5 is used to fully mix the gaseous carbon dioxide and water.

[0040] Further, such as Figure 2-4 The aeration plate 2 includes: a plate body 21; a cavity 22 disposed within the plate body 21; a plurality of aeration holes 23 disposed on one side of the plate body 21; and an air inlet 24 disposed at one end of the plate body 21. The plate body 21, cavity 22, aeration holes 23, and air inlet 24 are all located within the container 1, and the decompression assembly 4 is in communication with the air inlet 24. Specifically, during operation, gaseous carbon dioxide passes sequentially through the air inlet 24, cavity 22, and aeration holes 23, thereby increasing the contact area between the gaseous carbon dioxide and water. The plate body 21 is preferably made of micro-ceramics, and the aeration holes 23 have a pore size range of 0.5-0.8 μm, which allows the diameter of the mist bubbles escaping from the water to be within a range of 0.01-0.05 mm.

[0041] Further, such as Figure 2-4 The diameter of the aeration holes 23 gradually increases from one side to the other side of the plate body 21. Specifically, the diameter of the aeration holes 23 gradually decreases along the aeration direction, so that the flow rate of the gaseous carbon dioxide gradually increases along the aeration direction, thereby achieving a good aeration effect.

[0042] Further, such as Figure 3-4 , along the direction from one end to the other end of the plate body 21, the apertures of the aeration holes 23 gradually increase, or the spacing between adjacent aeration holes 23 gradually decreases. Specifically, Figure 3 , which is equivalent to gradually increasing the aperture of the plurality of aeration holes 23 along the air inlet direction, preventing a large amount of gaseous carbon dioxide from being aerated from the aeration holes 23 at one end of the plate 21, thereby making the aeration uniform; or Figure 4 , which is equivalent to gradually reducing the distance between adjacent aeration holes 23 along the air inlet direction, preventing a large amount of gaseous carbon dioxide from being aerated from the aeration holes 23 at one end of the plate body 21, thereby making the aeration uniform.

[0043] Further, such as Figure 1The water delivery assembly 3 includes a water pump 31, a first pressure reducing valve 32, a first control valve 33, and a first flow meter 34, which are connected in sequence. The end of the first flow meter 34, which is remote from the first control valve 33, is connected to one end of the container 1. Specifically, the water pump 31 is used to pump water. The water pump 31 can be a positive displacement pump, a vane pump, or the like. Because the pressure of the water delivered by the water pump 31 is too high, it is necessary to obtain water of a certain pressure through the first pressure reducing valve 32. The first pressure reducing valve 32 can be a piston pressure reducing valve, a diaphragm pressure reducing valve, or the like. The first control valve 33 is used to control the opening and closing of the water delivery assembly 3. The first control valve 33 can be a ball valve, a butterfly valve, or the like. The first flow meter 34 is used to detect the flow rate. The first flow meter 34 can be a positive displacement flow meter, a velocity flow meter, or the like.

[0044] Further, such as Figure 1 The pressure reducing assembly 4 includes: a second pressure reducing valve 41, a second control valve 42, and a flow controller 43, which are connected in sequence; a one-way valve 44, the inlet of which is connected to the end of the flow controller 43 away from the second control valve 42, and the outlet of which is connected to the plurality of aeration plates 2. Specifically, the second pressure reducing valve 41 is used to convert liquid carbon dioxide into gaseous carbon dioxide. The second pressure reducing valve 41 can be a piston-type pressure reducing valve, a diaphragm-type pressure reducing valve, or the like. The second control valve 42 is used to control the opening and closing of the pressure reducing assembly 4. The second control valve 42 can be a ball valve, a butterfly valve, or the like. The flow controller 43 is used to control the flow rate. The one-way valve 44 is used to prevent the reverse flow of the gaseous carbon dioxide.

[0045] Further, such as Figure 1 The pressure reducing assembly 4 further includes a first pressure gauge 45 connected between the second pressure reducing valve 41 and the second control valve 42. Specifically, the first pressure gauge 45 is used to detect pressure, and the first pressure gauge 45 can be a liquid column pressure gauge, an elastic pressure gauge, or the like.

[0046] Further, such as Figure 1 The mixing assembly 5 includes a second flowmeter 51, a mixer 52, and a third control valve 53, which are connected in sequence. The end of the second flowmeter 51, which is away from the mixer 52, is connected to the other end of the container 1. Specifically, the second flowmeter 51 is used to detect the flow rate and can be a volumetric flowmeter, a velocity flowmeter, etc. The mixer 52 is used to ensure that the gaseous carbon dioxide and water are fully mixed. The third control valve 53 is used to control the opening and closing of the mixing assembly 5 and can be a ball valve, a butterfly valve, etc.

[0047] Further, such as Figure 1 The mixer 52 includes a housing 521 connected between the second flow meter 51 and the third control valve 53; and a spiral blade 522 connected to the housing 521. Specifically, the housing 521 is used to support the spiral blade 522; and the spiral blade 522 facilitates the thorough mixing of the gaseous carbon dioxide and water.

[0048] Further, such as Figure 1 The mixing assembly 5 further includes a second pressure gauge 54 connected to the other end of the container 1 and the end of the second flowmeter 51 away from the mixer 52. Specifically, the second pressure gauge 54 is used to detect pressure, and the second pressure gauge 54 can be a liquid column pressure gauge or an elastic pressure gauge.

[0049] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
