[0024] The process of the high temperature and high pressure pulse catalytic electrocoagulation wastewater treatment system comprises the following steps:

[0025] The sedimentation treatment box performs preliminary sedimentation treatment on the impurities in the wastewater, and then passes the treated wastewater into the treatment tank. The wastewater is first injected into the placement chamber. After the placement chamber is filled with wastewater, the wastewater on the upper side flows to the right through the overflow partition into the heating treatment chamber. At the same time, the wastewater to be treated is injected into the wastewater chamber through the water inlet pipe. The driving component controls the rotating shaft, the first gear, and the extension rod magnetic block to rotate counterclockwise. During the rotation of the extension rod, the magnetic force between the magnetic block and the first magnetic plate pushes the sliding plate forward. At the same time, the sliding plate is stored in the movable frame when it is squeezed. The heat in the heating treatment chamber is introduced into the wastewater in the wastewater chamber through the arc plate between the heating treatment chamber and the wastewater chamber.

[0026] When the magnetic block rotates away from the first magnetic plate, the second elastic component controls the guide block and the movable frame to reset backwards, and the reciprocating sliding plate disturbs the wastewater in the wastewater chamber, so that the wastewater can be fully and efficiently heated by the heat dissipated in the heating treatment chamber. When the magnetic block rotates close to the second magnetic plate, it pushes the push plate to move backwards. During the movement of the push plate, the debris falling on the filter support plate is pushed so that the debris is pushed into the collection bucket. During the movement of the contact rod backwards, the raised part of the contact seat is pressed downwards, so that the air outlet head continuously swings in the vertical direction. The wastewater filtered by the filter support plate falls through the guide plate to form a water wall. The injection pump works to inject the catalyst into the falling wastewater through the feeding head. During the rotation of the first gear, the cam is controlled to rotate by the second gear.

[0027] During the rotation of the cam, the moving plate and the piston plate will be squeezed to move. During the movement of the piston plate, the gas in the air cylinder will be squeezed out and blown onto the falling water wall through the air pipe and the air outlet head. During the backward movement of the piston plate, the external gas will be sucked into the air cylinder through the first one-way valve, and the gas will be continuously blown onto the water wall at various angles through the swinging air outlet head, so that the catalyst in the water wall and the wastewater are mixed more evenly, and the high-pressure environment in the auxiliary heating treatment chamber is formed, and the stirring treatment of the stirring plate is cooperated to make the mixing between the catalyst and the wastewater more sufficient and uniform during the treatment process, and reduce the contact between the impurities in the wastewater and the catalyst and the wastewater. The pulse power supply and the booster fan work to pulse-activate the catalyst in the wastewater, and realize the electro-coagulation process to remove the suspended matter and heavy metals in the wastewater through flocculation and precipitation.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. In the present invention, a magnetic block, a second magnetic plate, a push plate, an overflow baffle, a filter support plate, a collection barrel, and an air outlet head are used. The overflow baffle can be used to form a water wall for the water flowing into the heating treatment chamber, and has a certain precipitation and filtering effect on the debris. The push plate is pushed by the magnetic force between the rotating magnetic block and the second magnetic plate, and cooperates with the third elastic component to realize the reciprocating forward and backward movement of the push plate. The push plate pushes the debris on the filter support plate into the collection barrel, and the feeding head sprays the catalyst on the water wall, so that the catalyst contacts the wastewater more evenly. The wastewater filtered and treated by the filter support plate and the overflow baffle forms a uniform water wall and is mixed with the catalyst, ensuring the mixing effect while sustainably filtering and treating the wastewater.

[0030] 2. In the present invention, an air outlet head, a contact seat and a contact rod are used, and the reciprocating contact rod can be used to squeeze the contact seat and the air outlet head to perform a small reciprocating up and down swing, and the wastewater with added catalyst is blown along various angles; the oblique upward blowing airflow can produce vertical and horizontal mixing effects in the water wall, and enhance the convection of the liquid through the interaction between the gas and liquid phases, thereby promoting the uniform distribution of the catalyst; the introduction of the airflow will generate turbulence in the water flow, increase the kinetic energy of the liquid, and help break the sedimentation trend of the catalyst in the water; the oblique upward blowing airflow can effectively break up the aggregation of the catalyst and prevent it from depositing in the water wall, ensuring that the catalyst is always in an active state, and increase the air pressure in the heating treatment chamber, making it easier to form a high-pressure environment.

[0031] 3. In the present invention, a stirring plate, an extension rod, a magnetic block and a driving assembly are used. The driving assembly controls the rotation of the extension rod and the stirring plate. The stirring plate stirs the wastewater in the heating treatment chamber, so that the catalyst in the wastewater is stirred, and the mixing between the wastewater and the catalyst plays a positive role. At the same time, during the rotation of the stirring plate and the magnetic block, the magnetic block controls the second magnetic plate to move back and forth, thereby automatically pushing and cleaning the debris remaining on the filter support plate, so that the overall processing process can automatically clean the filter support plate.

[0032] 4. In the present invention, a first magnetic plate, a sliding plate, a movable frame, a guide block and a first elastic component are used. The magnetic force between the magnetic block and the first magnetic plate is used to control the movable frame and the sliding plate to move forward, and the first elastic component is used to control the sliding plate to move backward. The reciprocating sliding plate disturbs the wastewater in the wastewater chamber, so that the heat in the heating treatment chamber is introduced into the wastewater in the wastewater chamber through the arc plate between the heating treatment chamber and the wastewater chamber. The preheating of the wastewater in the wastewater chamber is more sufficient and efficient, more energy-saving and ensures the catalytic treatment effect of the subsequent catalyst.

During the backward movement of the contact rod 147, the raised part of the contact seat 151 is pressed downward, so that the gas outlet head 152 continuously swings in the vertical direction. The wastewater filtered by the filter support plate 12 falls through the guide plate 25 to form a water wall. The injection pump 17 works to inject the catalyst into the falling wastewater through the feeding head 16. During the rotation of the first gear 201, the cam 203 is controlled to rotate through the second gear 202;

[0067] During the rotation of the cam 203, the movable plate 194 and the piston plate 192 are squeezed to move. During the movement of the piston plate 192, the gas in the air storage cylinder 191 is squeezed out, and the gas is blown onto the falling water wall through the air pipe 18 and the air outlet head 152. During the backward movement of the piston plate 192, the external gas is sucked into the air storage cylinder 191 through the first one-way valve 196, and the gas is continuously blown onto the water wall at various angles through the swinging air outlet head 152, so that the catalyst in the water wall and the wastewater are mixed more evenly, and the high-pressure environment in the auxiliary heating treatment chamber 6 is formed, and the stirring treatment of the stirring plate 113 is cooperated, so that the mixing between the catalyst and the wastewater during the treatment process is more sufficient and uniform, and the contact between the impurities in the wastewater and the catalyst and the wastewater is reduced.
