Waste gas purification equipment for garbage incinerator

Abstract

The invention discloses waste gas purification equipment for a garbage incinerator. The waste gas purification equipment comprises a purification box fixedly connected to the upper end of a water pipe; the left side wall of the purification box is connected with an air inlet pipe; the right side wall of the purification box is connected with an exhaust pipe; a first magnetic sliding plate and a second magnetic sliding plate are symmetrically and fixedly connected to the inner wall of the purification box through telescopic springs, a vertical rod is rotatably connected to the inner wall of thepurification box, the lower end of the vertical rod penetrates through the lower end of the purification box and is fixedly connected with a plurality of hydrodynamic wheels, and permanent magnet plates are symmetrically and fixedly connected to the side wall, located in the purification box, of the vertical rod. According to the invention, the two permanent magnet plates are driven by the hydrodynamic wheels to rotate ceaselessly; and then the first magnetic sliding plate and the second magnetic sliding plate are continuously close to and away from each other under the action of the elasticforce of a telescopic spring and the repulsive force of the permanent magnet plates, so that the purifying box continuously sucks waste gas to be in full contact with a purifying agent, a harmful gasin the waste gas is absorbed, and serious atmospheric pollution caused by exhaust of the waste gas into air is avoided.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a waste gas purification device for a garbage incinerator. Background technique [0002] Waste incineration is the process of reducing the volume of waste through oxidation at high temperature through appropriate thermal decomposition, combustion, melting and other reactions, and turning it into residue or molten solid matter. [0003] A large amount of waste gas will be produced after waste incineration, so the waste gas is often purified with a purification furnace during waste incineration. At present, the waste gas generated in the waste incinerator mostly enters the secondary combustion chamber and is completely burned under the forced combustion of the burner. Then enter the spray dust collector to remove the dust in the exhaust gas, and then discharge it into the atmosphere through the chimney. However, when the exhaust gas is discharged after burning, the exhaus...

[0003] A large amount of waste gas will be produced after waste incineration, so the waste gas is often purified with a purification furnace during waste incineration. At present, the waste gas generated in the waste incinerator mostly enters the secondary combustion chamber and is completely burned under the forced combustion of the burner. Then enter the spray dust collector to remove the dust in the exhaust gas, and then discharge it into the atmosphere through the chimney. However, when the exhaust gas is discharged after burning, the exhaust gas will be discharged out of the incinerator along with some harmful gases, which cannot be treated by the dust collector alone. These harmful gases are effectively purified, and then the exhaust gas is discharged into the air, which is easy to cause air pollution and is not conducive to environmental protection.
