Description

Technical Field

[0001] The utility model relates to the field of disinfectant production and processing, in particular to an online chlorine dioxide generator. Background Art

[0002] Chlorine dioxide is an internationally recognized safe, non-toxic green disinfectant. Due to its strong selective oxidation ability and broad-spectrum and efficient bactericidal ability, it has been used in many aspects such as pulp and fiber bleaching, drinking water disinfection, food processing, preservation, wastewater treatment, medical disinfection and sterilization, bleaching, water injection for oil production, oil well unblocking and biological pollution control.

[0003] Currently, chlorine dioxide generators generally use a chemical process to produce chlorine dioxide. Sodium chlorate and hydrochloric acid are combined at room temperature and under negative pressure to produce chlorine dioxide, chlorine gas, sodium chloride, and water. Existing chlorine dioxide generators mostly use a propeller-type stirring mechanism. This stirring mechanism causes the solution in the generator to move in a fixed direction as stirring progresses. This fixed movement reduces the number of collisions between active particles in the raw materials, thus affecting the final chlorine dioxide production efficiency and yield.

[0004] Therefore, it is necessary to design a chlorine dioxide online generator that can allow the reactive ions to fully collide and participate in the reaction. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention will be described in detail below with reference to the accompanying drawings. Example

[0026] like Figures 1 to 9 As shown, the utility model provides a chlorine dioxide online generator, which specifically includes a reaction kettle 1, a PLC controller 7, a vibration mechanism 2 and an electric-controlled quantitative valve 5;

[0027] Among them, the PLC controller 7 is arranged on the upper front side of the reactor 1, and the PLC controller 7 is electrically connected to each mechanism through a wire 8 for quickly controlling the operation of the device;

[0028] Among them, two sets of vibration mechanisms 2 are respectively set through the reactor wall on both sides of the reactor 1, and are used to make the reaction liquids in the reactor 1 collide with each other through vibration, so as to make the reaction more complete;

[0029] The electrically controlled quantitative valves 5 are arranged on the upper left and right sides of the reactor 1 to precisely control the total amount of reaction raw materials and the raw material ratio.

[0030] The vibration mechanism 2 specifically includes a vibration column 202, a vibration plate 201, a first motor 205 and a cam 204;

[0031] Among them, two vibration columns 202 are respectively arranged on both sides of the reactor wall, and the reactor 1 and the vibration columns 202 are slidably matched. One end of the vibration column 202 located in the reactor 1 is provided with a vibration plate 201, which is used to drive the liquid in the reactor 1 to shake and collide rapidly;

[0032] Among them, multiple springs 203 are evenly spaced between the outer wall of the reactor 1 and the outer side of the vibration column 202, and support shells 206 are provided on the left and right sides of the outside of the reactor 1. The first motor 205 is arranged on the top of the support shell 206, and the output shaft of the first motor 205 is connected to the cam 204 through a coupling. The outer side of the cam 204 is in contact with the vibration column 202, which is used to drive the cam 204 to rotate through the first motor 205, thereby driving the vibration column 202 to move, and the resetting of the vibration column 202 is controlled by the spring 203.

[0033] The electronically controlled valve specifically includes a discharge pipe 505, a stacking barrel 502, a feed pipe 501, a second motor 504 and a rotating shaft 503;

[0034] Among them, two discharge pipes 505 are respectively arranged on the upper part of both sides of the reactor 1, and the discharge pipes 505 pass through the reactor walls on both sides of the reactor 1. The stacking barrel 502 is arranged on the upper part of the discharge pipe 505, and the top of the stacking barrel 502 is provided with a feeding pipe 501 for injecting raw materials into the reactor 1;

[0035] Among them, the second motor 504 is arranged outside the material stacking barrel 502, and the rotating shaft 503 is rotatably arranged inside the material stacking barrel 502. A plurality of material troughs are opened outside the rotating shaft 503 and are connected to the rotating shaft 503 through a coupling.

[0036] For example, when feeding begins, raw materials enter from the feed pipe 501 and accumulate in the space formed by the stacking barrel 502 and the rotating shaft 503. At this time, the PLC control system controls the second motor 504 through the wire 8 to start working. The rotating shaft 503 begins to rotate as the second motor 504 starts. When the material trough of the rotating shaft 503 rotates to the side where the materials are piled in the stacking barrel 502, the raw materials enter the trough under the action of gravity. When the material trough of the rotating shaft 503 that holds the raw materials rotates to the side of the discharge pipe 505, the raw materials enter the reactor 1 through the discharge pipe 505. In this way, the amount of raw materials entering the reactor 1 can be adjusted based on the number of revolutions of the second motor 504, and the ratio of the raw materials entering the reactor 1 can be accurately controlled, thereby accelerating the reaction rate and improving the reaction efficiency within a certain period of time. After the raw materials enter the reactor 1, the PLC control component connects to the first motor 205 in the vibration mechanism 2 through the wire 8 to start working. Vibrating column 202, under the thrust of spring 203, maintains contact with the outer end of cam 204. After first motor 205 rotates cam 204, vibrating column 202, maintaining contact with the outer end of cam 204, drives vibrating plate 201 to begin vibrating. This vibration of vibrating plate 201 causes the reaction liquid in reactor 1 to collide from both sides toward the center. The electronically controlled metering valve 5 adjusts the amount of raw materials entering reactor 1 based on the rotational speed of second motor 504, precisely controlling the raw material ratio entering reactor 1. Simultaneously, vibrating mechanism 2 ensures sufficient collisions between active particles in the reaction liquid. This increases the reaction rate and improves reaction efficiency within a given timeframe. Example

[0037] like Figure 1 and Figure 8 As shown, based on Example 1, it specifically includes a jet mechanism 3, which includes a liquid inlet pipe 301, a liquid pump 302, a liquid outlet pipe 303 and a liquid spray plate 304. The top of the reactor 1 is provided with a liquid inlet pipe 301, one end of the liquid inlet pipe 301 passes through the top of the reactor 1, the outside of the liquid inlet pipe 301 is provided with a liquid pump 302, the liquid outlet of the liquid pump 302 is provided with a liquid outlet pipe 303, the liquid outlet pipe 303 passes through the rear side of the reactor 1, and the inside of the reactor 1 is provided with a liquid spray plate 304 near the liquid outlet pipe 303, and the liquid spray plate 304 is connected to the liquid outlet pipe 303.

[0038] While vibrating mechanism 2 is operating, the PLC control system, connected via wire 8, activates liquid pump 302 in fluid injection mechanism 3. Liquid inlet pipe 301 draws liquid from the lower front corner of reactor 1. The liquid is pressurized by liquid pump 302, flows through outlet pipe 303, and is ejected by spray plate 304. This allows active particles that have not yet reacted in the corners of reactor 1 to enter the central collision zone within reactor 1, ensuring a more complete reaction and improving reaction efficiency within a given timeframe.

[0039] like Figure 1 and Figure 8 As shown, on the basis of Example 1, an exhaust mechanism 6 is further included, and the exhaust mechanism 6 specifically includes an air inlet pipe 601, an air pump 602 and a safety valve 604. An air inlet pipe 601 is provided outside the reactor 1 and passes through one side of the reactor 1. The air inlet pipe 601 is connected to the air pump 602; an exhaust pipe 603 is provided at the air outlet of the air pump 602, and a safety valve 604 is provided outside the reactor 1. The exhaust port of the safety valve 604 passes through one side of the exhaust pipe 603.

[0040] Throughout this process, the PLC control system, connected via wire 8, controls the air pump 602 in the exhaust mechanism 6 to start operating. Air pump 602 operates to draw gas from the reactor 1 through the inlet pipe 601, passing through the pump 602 and exiting through the exhaust pipe 603. This creates a negative pressure environment within the reactor, allowing for the timely discharge of the reaction products, chlorine dioxide and chlorine, accelerating the reaction rate and improving reaction efficiency over a certain period of time. Furthermore, the presence of a safety valve 604 ensures that the pressure within the reactor remains within a safe range, ensuring both environmental and personnel safety.

[0041] like Figure 7 As shown, based on Example 1, a heat exchange grid 4 is further included. Inside the reactor 1, a heat exchange grid 4 is provided between the vibration plates 201 , and the liquid inlet and outlet of the heat exchange grid 4 pass through the rear wall of the reactor 1 .

[0042] While the vibrating mechanism 2 is operating, a heat exchange liquid at the same temperature as the required reaction temperature is injected into the liquid inlet at the bottom of the heat exchange grid 4. After heat exchange, the liquid is discharged through the liquid outlet at the top of the heat exchange grid 4. This allows the heat generated by the reaction to be promptly removed from the most intense reaction area within the reactor 1, maintaining a constant temperature within the reactor 1 and accelerating the reaction rate.
