Description

Technical Field

[0001] The present invention relates to the technical field of flue gas treatment, and in particular to a flue gas treatment device for domestic waste incineration power generation. Background Art

[0002] Domestic waste is processed by burning, and when the waste is burned, a large amount of smoke will be generated, and the smoke will be mixed with a large amount of garbage dust produced by the combustion. When the smoke is processed, the dust will enter the interior of the smoke disinfection and purification device, causing the interior of the smoke disinfection and purification device to be blocked, thereby removing the dust in the smoke while disinfecting and purifying the smoke.

[0003] After searching, the patent with announcement number CN116651121A discloses an environmentally friendly flue gas treatment device for waste incineration. Technical problem: The contact reaction time between flue gas and purified water is short, and soot easily blocks the nozzle. The technical solution of the present invention is: an environmentally friendly flue gas treatment device for waste incineration, comprising a tower body; a water pipe, a fixed plate, and a cleaning assembly; a plurality of water pipes are connected to the side wall of the tower body; each water pipe is fixedly connected to a fixed plate; each fixed plate is connected to a cleaning assembly, and the cleaning assembly is connected to the water pipe. The present invention sets the spray ring in a conical shape, so that part of the spray water can flow down along the conical surface of the spray ring, flushing away the soot and dirt attached to the spray hole, thereby cleaning the spray hole and preventing the soot from blocking the spray hole and affecting the purification effect. In addition, because the first guide ring is small in the middle and large at the upper and lower ends, the rising rate of the flue gas is slowed down, thereby increasing the contact reaction time between the purified water and the flue gas. However, while the flue gas treatment device removes dust from the flue gas by spraying, since the bottom surface of the device is horizontal and the dust that falls into the interior of the device is discharged through a sewage pipe installed at the bottom, the horizontal bottom surface cannot easily move the dust settled at the bottom. As a result, through long-term use, the sewage pipe will be clogged, and the dust accumulated inside cannot be discharged, which reduces the use of the device. Summary of the Invention
