Description

Technical Field

[0001] The invention relates to the technical field of disinfection and sterilization equipment, and in particular to a rapid generation device of gaseous chlorine dioxide. Background Art

[0002] The overflow duct of the existing chlorine dioxide gas generator on the market is narrow, and it cannot ensure that the chlorine dioxide gas will overflow quickly after it is generated; in addition, the main duct is arranged on the side of the beaker-type reaction chamber, which has large wind resistance and low ventilation flow, and the equipment is large in size and heavy in weight. The existing chlorine dioxide gas generator uses a single beaker-type reaction chamber. Due to the limitations of reaction conditions, the amount of reagents involved in a single reaction cannot be too large, resulting in a limited total amount of chlorine dioxide gas produced; in addition, the existing chlorine dioxide gas generator uses a single beaker-type reaction chamber. Only after the current batch of reagents has completely reacted and the waste liquid has been discharged can new reagents be added to carry out the next batch of reactions. There is a time interval in between, and chlorine dioxide gas cannot be produced continuously, and the amount of gas generated per unit time fluctuates greatly; finally, the reaction temperature of the existing chlorine dioxide gas generator cannot be controlled, and working in a low-temperature environment will reduce the chlorine dioxide gas production rate.

[0003] Therefore, it is necessary to provide a rapid generation device of gaseous chlorine dioxide, set up multiple reaction chambers, increase the generation and release rate of gaseous chlorine dioxide, optimize the layout position of the main air duct, and improve the diffusion rate of gaseous chlorine dioxide. Summary of the invention

[0004] In view of this, the object of the present invention is to provide a rapid generation device of gaseous chlorine dioxide, which eliminates the window period of gaseous chlorine dioxide generation by arranging multiple reaction chambers in the cavity and the time interval for injecting reactants, and continuously and stably generates gaseous chlorine dioxide; the cavity air duct is arranged above the reaction chamber, with small wind resistance and large ventilation flow, thereby improving the diffusion rate of gaseous chlorine dioxide.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A rapid generation device of gaseous chlorine dioxide comprises a cavity, a cavity upper cover, a cavity splint and a baffle cap, wherein the cavity upper cover is fixedly arranged on the top of the cavity; a reaction chamber is arranged in the cavity, a reactant injection port is arranged on the side wall of the reaction chamber, the cavity splint is horizontally arranged at the connection between the cavity and the cavity upper cover, and a splint through hole corresponding to the reaction chamber is arranged on the cavity splint; an air inlet and an air outlet are arranged on the side wall of the cavity upper cover, a cavity air duct is arranged between the air inlet and the air outlet in the cavity upper cover, a baffle cap mounting column corresponding to the center of the reaction chamber and extending toward the reaction chamber is arranged on the top wall of the cavity upper cover, the lower end of the baffle cap is suspended on the upper part of the reaction chamber and arranged below the splint through hole, and the upper end of the baffle cap passes through the splint through hole to be connected with the baffle cap mounting column.

[0007] Preferably, the number of the reaction chambers is not less than two. Two or more reaction chambers can be set according to the reaction needs. The reactant is injected into a reaction chamber through the reactant injection port. After the reagent in the reaction chamber reacts for a period of time, the reagent is injected into it through the reactant injection port of another reaction chamber. When multiple reaction chambers are provided in the chamber, the same is true. Since there is an interval between the time when the two reaction chambers are injected with reactants, the overall measurement of reactants participating in the reaction in the chamber is increased, and gaseous chlorine dioxide is generated more efficiently.

[0008] Preferably, an air duct windshield is provided in the cavity air duct of the cavity upper cover, and the air duct windshield is vertically arranged on the side wall of the cavity upper cover between the air inlet and the air outlet. The cavity air duct is placed above the reaction chamber, and the air flow enters from the air inlet and leaves from the air outlet. The wind resistance is small and the ventilation flow is large. According to the Bernoulli principle, the gas flow rate in the cavity air duct is fast and the pressure is small, and the chlorine dioxide gas generated in the beaker-type reaction chamber can be brought out in time and quickly, which greatly improves the diffusion rate of gaseous chlorine dioxide. After the air duct windshield is added to the cavity air duct, the air flow in the cavity air duct is longer, and it is easier to bring out the chlorine dioxide gas generated in the reaction chamber and send it out from the air outlet.

[0009] Preferably, the bottom of the blocking cap is a circular plane, the top of the blocking cap is a conical surface, the top of the conical surface is provided with a cylinder with a threaded hole, and the cylinder is screwed and fixed to the mounting column of the blocking cap. The chlorine dioxide gas generated in the reaction chamber flows upward from the edge of the circular plane at the bottom of the blocking cap, passes through the through hole of the clamping plate, and is brought out into the cavity air duct in the upper cover of the cavity, and an S-shaped overflow air duct is formed between the blocking cap and the through hole of the clamping plate.

[0010] Preferably, the outer diameter of the bottom of the blocking cap is larger than the diameter of the through hole of the clamping plate. The S-shaped overflow air duct has a large ventilation cross-sectional area, which greatly increases the overflow rate of chlorine dioxide gas and prevents the reaction liquid from splashing due to violent reaction.

[0011] Preferably, an electric heating plate is fixedly provided at the bottom of the cavity corresponding to the position of the reaction chamber. The electric heating plate can automatically detect and control the reaction temperature, control the reaction temperature in the reaction chamber at the optimal reaction temperature, and increase the rate of generating gaseous chlorine dioxide. The reaction temperature in the reaction chamber can be controlled, which can ensure that the generation rate of gaseous chlorine dioxide will not be affected by the low ambient temperature.

[0012] Preferably, a cavity drain port is provided at the bottom of the reaction chamber. After the reactants in the reaction chamber are completely reacted, they are discharged through the cavity drain port, and then new reagents are injected from the reactant injection port for the next cycle of reaction. Since there is an interval between the injection of reactants between multiple reaction chambers, when the reagents in one reaction chamber are completely reacted and enter the process of draining and injecting new reagents, the other reaction chamber is still working, thereby eliminating the window period for the production of gaseous chlorine dioxide, and achieving continuous and stable production of gaseous chlorine dioxide.

[0013] Preferably, the cavity and the cavity cover are fixedly connected by screws, and the screws are hexagon socket head screws. The cavity and the cavity cover are fixed together by using hexagon socket head screws to ensure that the device has a compact structure and is easy to install.

[0014] Preferably, a cavity sealing groove is provided on the top end surface of the cavity, a cover sealing protrusion matching the cavity sealing groove is provided at the bottom of the cavity cover, and a sealant is provided between the cavity sealing groove and the cover sealing protrusion. Since the reactant increases the pressure in the cavity during the reaction process, the cavity sealing groove cooperates with the cover sealing protrusion and the sealant is poured into the gap to ensure the sealing of the cavity.

[0015] Preferably, the cavity clamp is arranged on the inner side of the connection between the cavity sealing groove and the upper cover sealing protrusion. Such arrangement can ensure that the cavity clamp cooperates with the baffle cap to form an S-shaped overflow air duct without destroying the sealing of the cavity.

[0016] The beneficial effects of the present invention are as follows: Due to the adoption of the above technical solution, the present invention eliminates the window period of gaseous chlorine dioxide caused by the drainage and filling process in the reaction chamber by setting multiple reaction chambers, and there is a time interval between the injection of reactants in the multiple reaction chambers, thereby improving the measurement of the reactants participating in the reaction in the cavity as a whole, and generating gaseous chlorine dioxide more efficiently, continuously and stably. The cavity air duct is placed above the reaction chamber, with small wind resistance, large ventilation flow, fast gas flow rate in the cavity air duct, and low pressure, and the chlorine dioxide gas generated in the beaker-type reaction chamber can be quickly taken out from the S-shaped overflow air duct in time, which greatly improves the diffusion rate of gaseous chlorine dioxide.

[0030] like Figure 1-Figure 6 As shown, a rapid generation device of gaseous chlorine dioxide comprises a cavity 1, a cavity cover 2, a cavity clamp 6 and a stop cap 7, wherein the cavity cover 2 is fixedly arranged on the top of the cavity 1. The cavity 1 and the cavity cover 2 are fixedly connected by screws 8, and the screws 8 are hexagon socket head screws. The cavity 1 and the cavity cover 2 are fixed together by using hexagon socket head screws to ensure that the structure of the device is compact and easy to install.

[0031] A reaction chamber 11 is provided in the cavity 1, and a reactant injection port 12 is provided on the side wall of the reaction chamber 11. The reactant injection port 12 is fixed to the side wall of the reaction chamber 11 by a threaded connection and is connected to the reaction chamber 11. The cavity clamp 6 is horizontally arranged at the connection between the cavity 1 and the cavity upper cover 2, and a clamp through hole 61 corresponding to the reaction chamber 11 is provided on the cavity clamp 6.

[0032] An air inlet 3 and an air outlet 4 are provided on the side wall of the cavity upper cover 2, a cavity air duct 21 is provided between the air inlet 3 and the air outlet 4 in the cavity upper cover 2, a baffle cap mounting column 22 corresponding to the center of the reaction chamber 11 and extending toward the reaction chamber 11 is provided on the top wall of the cavity upper cover 2, the lower end of the baffle cap 7 is suspended on the upper part of the reaction chamber 11 and is arranged below the splint through hole 61, and the upper end of the baffle cap 7 passes through the splint through hole 61 and is connected with the baffle cap mounting column 22.

[0033] An air duct windshield 24 is provided in the cavity air duct 21 of the cavity upper cover 2, and the air duct windshield 24 is vertically arranged on the side wall of the cavity upper cover 2 between the air inlet 3 and the air outlet 4. The cavity air duct 21 is placed above the reaction chamber 11, and the air flow enters from the air inlet 3 and leaves from the air outlet 4. The wind resistance is small and the ventilation flow rate is large. According to the Bernoulli principle, the gas flow rate in the cavity air duct 21 is fast and the pressure is small, and the chlorine dioxide gas generated in the beaker-type reaction chamber 11 can be taken out in time and quickly, which greatly improves the diffusion rate of chlorine dioxide gas. After the air duct windshield 24 is added to the cavity air duct 21, the air flow in the cavity air duct 21 is longer, and it is easier to take out the chlorine dioxide gas generated in the reaction chamber 11 and send it out from the air outlet 4.

[0034] The number of the reaction chambers 11 is not less than two. Two or more reaction chambers 11 can be set according to the reaction needs. The reactant is injected into a reaction chamber 11 through the reactant injection port 12. After the reagent in the reaction chamber 11 reacts for a period of time, the reagent is injected into another reaction chamber 11 through the reactant injection port 12. When multiple reaction chambers 11 are provided in the cavity 1, the same is true. Since there is an interval between the time when the two reaction chambers 11 are injected with the reactant, the overall reactant metering participating in the reaction in the cavity 1 is increased, and gaseous chlorine dioxide is generated more efficiently.

[0035] The bottom of the blocking cap 7 is a circular plane, the top of the blocking cap 7 is a conical surface, the top of the conical surface is provided with a cylinder with a threaded hole, and the cylinder is screwed and fixed to the blocking cap mounting column 22. The outer diameter of the bottom of the blocking cap 7 is greater than the diameter of the clamping plate through hole 61. The chlorine dioxide gas generated in the reaction chamber 11 is carried out from the edge of the circular plane at the bottom of the blocking cap 7 upward, through the clamping plate through hole 61 to the cavity air duct 21 in the cavity upper cover 2, and an S-shaped overflow air duct is formed between the blocking cap 7 and the clamping plate through hole 61. The ventilation cross-sectional area of ​​the S-shaped overflow air duct is large, which not only greatly increases the overflow rate of the chlorine dioxide gas, but also prevents the reaction liquid from splashing due to violent reaction.

[0036] An electric heating plate 5 is fixedly provided at the bottom of the cavity 1 at a position corresponding to the reaction chamber 11. The electric heating plate 5 can automatically detect and control the reaction temperature, control the reaction temperature in the reaction chamber 11 at the optimal reaction temperature, and increase the rate of generating gaseous chlorine dioxide. The reaction temperature in the reaction chamber 11 can be controlled, which can ensure that the generation rate of gaseous chlorine dioxide will not be affected by the low ambient temperature.

[0037] The bottom of the reaction chamber 11 is provided with a cavity drain port 13. The cavity drain port 13 is fixed to the bottom of the reaction chamber 11 by a threaded connection and is connected to the reaction chamber 11. After the reactant in the reaction chamber 11 is completely reacted, it is discharged through the cavity drain port 13, and then a new reagent is injected from the reactant injection port 12 for the next cycle of reaction. Since there is an interval between the injection of reactants between the multiple reaction chambers 11, when the reagent in one of the reaction chambers 11 is completely reacted and enters the process of draining and injecting new reagents, the other reaction chamber 11 is still working, thereby eliminating the window period for the production of gaseous chlorine dioxide, and achieving continuous and stable production of gaseous chlorine dioxide.

[0038] The top end surface of the cavity 1 is provided with a cavity sealing groove 14, the bottom of the cavity upper cover 2 is provided with an upper cover sealing protrusion 23 matching the cavity sealing groove 14, and a sealant is provided between the cavity sealing groove 14 and the upper cover sealing protrusion 23. Since the reactant increases the pressure in the cavity 1 during the reaction process, the cavity sealing groove cooperates with the upper cover sealing protrusion and the sealant is poured into the gap to ensure the sealing of the cavity 1.

[0039] The cavity clamping plate 6 is arranged on the inner side of the connection between the cavity sealing groove 14 and the upper cover sealing protrusion 23. Such arrangement can ensure that the cavity clamping plate 6 cooperates with the blocking cap 7 to form an S-shaped overflow air duct without destroying the sealing performance of the cavity 1.
