7. A method for recovering the residual heat of the energy-saving burner according to the claims 1-6, characterized by comprising the following steps:
firstly, a power supply is switched on, an electric valve is opened through a switch group, cold water is injected into a box body through a water injection pipe, the valve is opened simultaneously, water is added into a water tank through a water inlet pipe, and a floating ball floats upwards due to the rising of the water level in the box body;
step two, the connecting rod is driven to move upwards, the limiting block is extruded into the groove after the connecting rod moves to the target position, and the limiting block is contacted with the switch after the groove moves to the target position;
step three, closing the electric valve through the switch, driving the connecting rod to move downwards to extrude the limiting block if the water level in the box body is reduced, enabling the limiting block to contact the switch after moving to the target position, opening the electric valve again through the switch, and injecting the target amount of water;
step four, closing the valve, simultaneously opening the water pump through the switch group, when the industrial furnace burns, high-temperature flue gas can enter the copper pipe along the smoke exhaust pipe, the copper pipe has good heat conductivity, heat in the flue gas and cold water in the box body can be exchanged, and the flue gas after heat exchange enters the collecting box through the guide of the pipe body
Step five, because the diversion flue gas of the diversion plate can move upwards, the particles in the flue gas can automatically fall downwards, meanwhile, when the water pump works, the water in the box body can be pumped into the connecting pipe and guided into the water outlet pipe by the connecting pipe, and through the pressure of the water pump during working, the water in the water outlet pipe is sprayed out through the water outlet to reduce dust of the flue gas, and the water after reducing dust enters the through hole and is filtered by the filter screen plate and then returns to the water tank;
and step six, after the flue gas is washed by water and subjected to dust reduction, secondary filtration is carried out by the activated carbon filter screen again, dust particles in the flue gas are filtered, and the filtered flue gas can be discharged to the atmosphere through a chimney.
