The stage aeration reaction further helps the chlorine dioxide gas react more fully to improve the purity of the chlorine dioxide gas.
[0027] Further, in order to facilitate the overflow of the pre-mixed raw materials from the liquid outlet 112 into the first aeration reaction chamber 121, at the same time, the mixed raw materials enter the aeration reaction chamber group 12 for stepwise multi-stage aeration reaction. Contribute to the overall generation of process linkages to improve the purity of chlorine dioxide gas. The aeration reaction chamber includes a first aeration reaction chamber 121, a second aeration reaction chamber 122, and a third aeration reaction chamber that are sequentially connected and have decreasing volumes.

Specifically, in this embodiment, the aeration ports 1233 are respectively arranged at the bottom of the first aeration reaction chamber 121, the second aeration reaction chamber 122, and the third aeration reaction chamber 123. The inlet 1212 and the outlet 1232 are respectively arranged in the middle and lower parts of the first aeration reaction chamber 121, the second aeration reaction chamber 122 and the third aeration reaction chamber 123, and the inlet 1212 and the outlet 1232 are respectively opened On the left and right sides of the first aeration reaction chamber 121, the second aeration reaction chamber 122 and the third aeration reaction chamber 123. The chlorine dioxide gas overflow port 1234 is respectively arranged at the top of the first aeration reaction chamber 121, the second aeration reaction chamber 122 and the third aeration reaction chamber 123. It should be noted that, for the sake of simplicity, the first aeration reaction chamber 121, the second aeration reaction chamber 122, and the third aeration reaction chamber 123 of the present embodiment have the feed port 1212, the discharge port 1232, and the aeration port 1233. As well as the chlorine dioxide gas overflow port 1234, both can be represented by the same reference number, without distinction.
[0030] Specifically, the raw material inlets 111 may be set to two, so that the raw materials for producing chlorine dioxide can be introduced into the raw material premixing bin 11 through different raw material inlets 111 respectively. In more detail, one of them is introduced into the raw material pre-mixing bin 11 through the first raw material inlet 111, and the other one of the raw materials producing chlorine dioxide is introduced into the raw material pre-mixing bin 11 through the second raw material inlet 111.
[0031] In addition, it should be noted that the aeration reaction chamber group 12 of the embodiment of the present invention is preferably set to three, that is, the first aeration reaction chamber 121, the second aeration reaction chamber 122 and The third aeration reaction chamber 123. Understandably, the first aeration reaction chamber 121, the second aeration reaction chamber 122, and the third aeration reaction chamber 123 are three intersecting step aeration reaction chambers. The aeration reaction chamber group 12 includes, but is not limited to, three aeration reaction chambers. The number of aeration reaction chambers can be increased on the three aeration reaction chambers, so that the pre-mixed raw materials can be subjected to more than three steps of step aeration. Air blow off. In addition, it can also be set according to the parameters of the relationship between the three aeration reaction chambers, and the parameters can be enlarged or reduced in the same proportion to meet different changes in the demand for chlorine dioxide.
[0032] Specifically, the first aeration reaction chamber 121, the second aeration reaction chamber 122, and the third aeration reaction chamber 123 are all designed in a cylindrical shape made of high-polyester PVC material, so that the pre-mixed raw materials can be subjected to a three-stage ladder. Step aeration blow off. The first aeration reaction chamber 121 is connected to the first exhaust pipe 1211, the second aeration reaction chamber 122 is connected to the second exhaust pipe 1221, the third aeration reaction chamber 123 is connected to the third exhaust pipe 1231, and the first exhaust pipe 1211. The second exhaust pipe 1221 and the third exhaust pipe 1231 are converged on a chlorine dioxide exhaust manifold 125 so as to collect the chlorine dioxide gas and output it to the work space.
[0033] Further, considering the size of the volume of the raw material pre-mixing bin 11, the ratio of raw material entering, the amount of entering, and the time of entering are determined. At the same time, the purity of the output of chlorine dioxide and the mixing ratio of raw materials, the time of reaction with the raw materials, and It is directly related to the volume of the aeration chamber. Therefore, in order to make the raw materials react more fully in the rear-end step aeration reaction chamber, and thereby produce high-purity chlorine dioxide, the volume of the raw material pre-mixing chamber 11 is The total volume ratio of the aeration reaction chamber group 12 is set to 1:13.6; the volume decline rate of the first aeration reaction chamber 121, the second aeration reaction chamber 122, and the third aeration reaction chamber 123 is set to 0.5 times. Preferably, the ratio of the volume of the raw material pre-mixing chamber 11 to the volume of the first aeration reaction chamber 121 is set to 1:5, and the volume ratio of the volume of the raw material pre-mixing chamber 11 to the second aeration reaction chamber 122 is set to 1:4.5 , The ratio of the volume of the raw material pre-mixing chamber 11 to the volume of the third aeration reaction chamber 123 is set to 1:4.0.
[0034] The following is an example of the setting relationship between the volume of the raw material premixing bin 11 and the aeration reaction bin group 12, see Table 1. Specifically, the ratio of the volume of the premixing bin to the total volume of the aeration reaction bin group 12 is 1:13.6 times, and the volume decline rate of each step aeration bin is 0.5 times. The volume ratio of the raw material pre-mixing chamber 11 to the first aeration reaction chamber 121 is set to 1:5, the volume ratio of the raw material pre-mixing chamber 11 to the second aeration reaction chamber 122 is set to 1:4.5, The volume ratio of the mixing chamber 11 to the volume of the third aeration reaction chamber 123 is set to 1:4.0.
[0035]
[0036] Table 1
[0037] Due to our compliance with this volume ratio, the purity of chlorine dioxide produced is high.
[0038] Further, in this embodiment, in sodium chlorite or sodium chlorite plus citric acid or hydrochloric acid as raw materials, we select sodium chlorite and hydrochloric acid as raw materials to obtain chlorine dioxide, and the reaction equation is:
[0039] 2ClO 2 +H 2 O-HClO 2 +HClO 3
[0040]
[0041] According to the reaction equation, choose sodium chlorite and hydrochloric acid as raw materials to react chlorine dioxide, set the sodium chlorite concentration to 7-10%, and select a concentration point; set the hydrochloric acid concentration to 6-9%, select one For the concentration point, set the reaction volume of sodium chlorite solution to 75ml/H, and set the reaction volume of hydrochloric acid solution to 82.5ml/H, then the theoretical output of chlorine dioxide after the reaction should be above 5000mg/H. By setting the concentration and amount of raw materials, following the setting relationship between the volume of the raw material pre-mixing bin 11 and the volume of the through step aeration bin in Table 1, the output of chlorine dioxide is 5100mg, which reaches the theoretical output .
[0042] In addition, in order to further set the relationship between the total amount of reaction liquid in the aeration reaction chamber group 12 and the total amount of aeration, the raw materials can be more fully reacted in the aeration chamber group, thereby enabling the production of high-purity chlorine dioxide. The ratio of the total amount of reaction liquid to the total amount of aeration in the aeration reaction chamber group 12 is set to 169:1.
[0043] The following is an example for setting the relationship between the total amount of reaction liquid in the aeration reaction chamber group 12 and the total amount of aeration, see Table 2.
[0044]
[0045] Table 2
[0046] Take 1 in Table 2 as an example to further illustrate the setting relationship between the total amount of the reaction liquid and the total amount of aeration: still take sodium chlorite and hydrochloric acid as the chlorine dioxide reaction raw materials, the description is as follows:
[0047] The reaction equation is:
[0048] 2ClO 2 +H 2 O-HClO 2 +HClO 3
[0049]
[0050] Sodium chlorite and hydrochloric acid are pre-mixed as liquid raw materials → overflow into the first aeration reaction chamber 121 for aeration blow off → at this time, the volume of the liquid in the first aeration reaction chamber 121 is 169.60 ml → required aeration The air volume should be kept at 1.0L/min.
[0051] When the raw material of the aeration chamber 1 overflows to 169.60ml → the raw material automatically overflows into the second aeration reaction chamber 122 to continue aeration and blowing off → the volume of the liquid in the second aeration reaction chamber 122 at this time is 141.30ml → required The aeration volume should be maintained at 0.83L/min.
[0052] When the raw material of the aeration chamber 2 overflows to 141.30ml → the raw material automatically overflows into the third aeration reaction chamber 123 to continue aeration and blowing off → at this time the volume of the third aeration reaction chamber 123 is 113.1ml → required The aeration volume should be maintained at 0.67L/min.
[0053] In the above three step aeration, each aeration reaction chamber is provided with a chlorine dioxide gas overflow port 1234 at the upper end to facilitate the overflow of the chlorine dioxide blown off by the aeration. It is further set by the relationship between the amount of reaction liquid in each aeration reaction chamber and the total amount of aeration. According to this relationship, the step aeration blow-off is set to facilitate the aeration reaction device of the chlorine dioxide gas. To obtain high-purity chlorine dioxide gas.
[0054] In addition, referring to Table 3, the purity of the chlorine dioxide gas can be further improved by controlling the ratio of the raw materials and the speed at which the raw materials enter the aeration reaction chamber group 12. Specifically, the speed at which the raw materials enter the aeration reaction chamber group 12 refers to how long the raw materials stay in the aeration reaction chamber group 12 for reaction and are completely aerated and blown off.
