Garbage incinerator spray tower and garbage incinerator

Abstract

The invention discloses a garbage incinerator spray tower and a garbage incinerator. An activated carbon adsorption device and an induced draft fan are arranged between a flue gas inlet of the spray tower and a secondary combustion chamber of the garbage incinerator. The spray tower comprises a hollow tower body, and a flue gas outlet is formed in the top of the tower body; a slurry settling tank at the bottom, a reaction area in the middle and a demisting area at the top are arranged in the tower body; a spraying mechanism is arranged in the reaction area; a demisting plate and a flusher are arranged in the demisting area; a flue gas inlet is formed in the surface of one side of the reaction zone, and a filler layer is arranged on the inner wall of the tower body above the flue gas inlet; an alkali liquor pool is arranged at one side of the tower body and is communicated with the tower body through a circulating pipeline; and a water supplementing and discharging mechanism is arranged at one side of the tower body and is connected with the alkali liquor pool through a pipeline; The garbage incinerator spray tower and the garbage incinerator have the characteristics that the contact duration of flue gas and spraying liquid can be adjusted, the circulating liquid can be automatically cooled, the PH value and the ion concentration of the circulating liquid can be regulated and controlled in real time, the automation degree is high, and the desulfurization and deacidification efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of garbage incineration, and in particular relates to a spray tower of a garbage incinerator and a garbage incinerator. Background technique [0002] The combustion process of waste incineration occurs in the primary combustion chamber and the secondary combustion chamber. The temperature of the exhaust gas discharged from the secondary combustion chamber is very high. Direct discharge will not only damage the chimney structure, but also have an impact on the surrounding environment, and the waste also contains S , Cl and other elements, after burning, they will generate harmful acid gases such as SO2 and HCl, which must be cooled and filtered by cooling, acid removal and other devices before they can be discharged. Therefore, it is necessary to set up a spray tower for spray acid removal and cooling operations; the existing spray tower has the following disadvantages: 1. The temperature of the cooling liqui...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a spray tower of a garbage incinerator and a garbage incinerator. The cooling effect is always kept within the preset range, and the pH and concentration of the circulating fluid cannot be automatically adjusted in real time. It can adjust the contact time between the flue gas and the spraying fluid, the circulating fluid can cool down automatically, and the circulating fluid can be adjusted in real time. PH value and ion concentration, high degree of automation, improved desulfurization and deacidification efficiency
