[0002] Three wastes refer to waste gas, waste liquid and waste residue. Solid waste and liquid waste are mostly treated separately. Solid waste and liquid waste are burned separately in independent incinerators, and the tail gas generated after burning is treated in an independent tail gas treatment system. The equipment utilization rate is low. There are also methods of mixing solid waste and liquid waste for incineration and then treating the tail gas uniformly. After solid-liquid mixed combustion, pollutants such as dust and sulfur dioxide are generated.

DETAILED DESCRIPTION

[0041] Referring to Figure 2 , the flue gas pipe 11 is provided with a cooling device 9 for cooling flue gas in the flue gas pipe 11, and the cooling device 9 comprises a shell 91, a cooling circulation pipe 92 and a heat exchange device 93. The cooling circulation pipe 92 comprises a heat absorption section 921 arranged in a curve, the heat absorption section 921 is fixedly arranged in the shell 91, the shell 91 is communicated with the flue gas pipe 11, and the two ends of the cooling circulation pipe 92 are connected with the heat exchange device 93.

[0042] The purpose of cooling the flue gas is achieved by the cooling device 9. Since the reaction of sulfur dioxide with lye to form calcium sulfite is reversible, the effect is usually best at a temperature of 50-60 degrees. Since the high-temperature flue gas exchanges heat with the heat-absorbing section 921 of the cooling circulation pipe 92 in the shell 91, the temperature of the flue gas is effectively reduced, which can effectively improve the desulfurization effect. Compared with the cooling method of spraying cold water in the tower body, the purity of the gypsum can be effectively guaranteed; and the dust in the flue gas is finally collected in the lye after being adsorbed by water.

[0043] With reference to Figure 2 , a centrifugal ring 8 is sleeved on the tower body along the circumference of the tower body, and a centrifugal cavity is formed between the centrifugal ring 8 and the tower body. The centrifugal ring 8 is sealingly connected to the tower body, and the output end of the flue gas pipe 11 communicates with the centrifugal ring 8. The distance between the side wall of the centrifugal ring 8 away from the tower body and the tower body gradually decreases along the direction of movement of the flue gas, and the centrifugal ring 8 is in communication at the head and tail.

[0044] With reference to Figure 2 and Figure 3 , the angle between the direction of the flue gas speed at the output end of the flue gas pipe 11 and the horizontal tangent direction of the side wall of the tower body is less than ninety degrees, so as to avoid the flue gas entering the centrifugal ring 8 along the radial direction of the tower body. The tower body is provided with a spraying bin 24 and a lye bin 25, and a plurality of filter holes 26 (see Figure 4 ) are formed in the side wall of the tower body and communicate the centrifugal ring 8 and the spraying bin 24.

The dust in the flue gas, especially the large-particle dust, is separated out, and the flue gas does circular motion in the centrifugal ring 8. Under the action of the centrifugal force, the larger dust falls, further purifying the dust in the flue gas. After the lye reacts with sulfur dioxide, gypsum is formed, preventing the dust from entering the tower body and then entering the lye bin 25, thereby affecting the purity of the gypsum.
