[0014] Beneficial effects of the present invention:

[0015] 1. When using the device, when it is necessary to increase the intake temperature, set the temperature value through the control panel. After the electric heating plate works for a period of time, the air inside the heating box is heated. At this time, the motor drives the fan blades to rotate, and the air enters the shell after being filtered through the external filter element, and then enters the interior of the heating box through the exhaust duct. After being heated by the electric heating plate, it enters the interior of the connecting pipe and records the temperature through the temperature sensor, and finally is discharged through the connecting pipe. When it is necessary to lower the intake temperature, the electric cylinder drives the rack to move, and the rack is meshed with the first gear, so that the coolant discharge check valve drives the magnetic tube at one end to rotate, and one end of the magnetic tube contacts the connector located above, and the second power-on piece of the connector contacts the first power-on piece of the magnetic tube. The magnetic tube is energized to generate magnetic force and adsorb the magnetic plate. The magnetic plate moves to squeeze the spring and open the coolant inlet. At this time, the motor drives the rotating rod to rotate synchronously through the transmission mechanism, and the rotating rod drives the turntable to rotate. The turntable drives the connecting rod to move and drives the piston at the other end of the connecting rod to slide back and forth inside the sealing tube, so that the coolant inside the coolant tank enters and passes through the coolant inlet check valve. The over-discharge coolant is discharged through the one-way valve to the inside of the connector, and then enters the inside of the cooling pipe through the connector. After the circumferential surface of the cooling pipe and the heating box is subjected to heat exchange treatment, it is recycled again inside the coolant tank through the coolant discharge pipe. The reaction process of the sulfuric acid converter is very sensitive to temperature. Different reaction stages may require different temperature conditions. The equipment has the function of rapid heating and cooling, and can quickly adjust the intake temperature to the appropriate range according to the reaction requirements to ensure that the reaction is carried out at the optimal temperature. Rapid heating and cooling helps to achieve precise control of the intake temperature, thereby providing more stable process control. By adjusting the intake temperature in time, process instability and output fluctuations caused by excessively high or low temperatures can be avoided, ensuring the stable operation of the sulfuric acid converter and the consistency of product quality. Since rapid heating and cooling can achieve the required temperature changes in a short time, the equipment can reach a stable working state faster, thereby reducing energy waste and consumption. Through effective temperature control, the energy use of the equipment can be optimized and the energy efficiency of the sulfuric acid conversion process can be improved.

[0016] 2. When the intake air temperature rises or drops, the rotating rod drives the stirring rod to stir the internal coolant. At the same time, the exhaust pipe sends cooling air into the coolant tank through the first exhaust valve and dissipates heat from the coolant inside the coolant tank. The introduction of cold air and the stirring of the stirring rod can increase the contact area with the coolant, accelerate the heat exchange process, achieve a faster cooling effect, and avoid the problem of reduced heat dissipation efficiency due to excessive coolant temperature.

The circumferential surface of the coolant tank 11 is provided with a switching mechanism.

[0026] When the device is used, if the intake air temperature needs to be increased, the temperature value is set through the control panel 41. After the electric heating plate 7 works for a period of time, the air inside the heating box 6 is heated. At this time, the motor 3 drives the fan blades 4 to rotate, and the cold air enters the interior of the heating box 6 through the exhaust pipe 5. After being heated by the electric heating plate 7, it enters the interior of the connecting pipe 9 and records the temperature through the temperature sensor 10 and transmits the signal to the processor 39. The hot air is discharged through the connecting pipe 9 to increase the intake air temperature.

The sealing tube slides back and forth inside, so that the coolant inside the coolant tank 11 enters through the coolant inlet check valve 18 and is discharged to the inside of the connector 25 through the coolant outlet check valve 19, and then enters the cooling pipe 8 through the connector 25. After the circumferential surface of the cooling pipe 8 and the heating box 6 is subjected to heat exchange treatment, the coolant is recycled again inside the coolant tank 11 through the coolant outlet pipe 42, so that the temperature of the heating box 6 can be quickly reduced, and the subsequent exhaust air can reach the specified temperature.
