DETAILED DESCRIPTION

[0014] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0015] like Figure 1-3 An RTO post-cooling tower shown in the figure comprises a tower body 1 with cooling water filled in the bottom of the inner cavity, an air inlet 2 is opened at the top of the tower body 1, an air outlet pipe 3 is installed on the outer wall of the tower body 1, the air outlet pipe 3 extends to the inside of the tower body 1, the bottom end of the air outlet pipe 3 located on the inner side of the tower body 1 is bent upward and extends for a distance, an air outlet baffle 4 is installed on the inner wall of the tower body 1, the air outlet baffle 4 is located on one side of the end of the air outlet pipe 3, a first filling assembly and a second filling assembly are respectively installed inside the tower body 1, a spray pipe 5 is installed above the first filling assembly and the second filling assembly, and a water inlet pipe 6 connected with the spray pipe 5 is installed on the outer side of the tower body 1;

[0016] On the basis of the above, during operation, the exhaust gas enters the interior of the tower body 1 from the air inlet 2 at the top of the tower body 1, and a spray head is installed on the spray pipe 5. The cooling liquid is sprayed through the spray pipe 5 to cool the exhaust gas. The treated exhaust gas follows the first filling component and the second filling component, turns at the bottom of the inner cavity of the tower body 1, enters the exhaust pipe 3 from the upward bent end of the exhaust pipe 3, and is discharged to the outside.

[0017] A plurality of observation windows 7 are provided outside the tower body 1 , through which the working status inside the tower body 1 can be observed, and the working status of the equipment can be processed and adjusted in real time.

[0018] An outer chamber 8 communicating with the interior of the tower body 1 is fixed on the outer wall at the bottom end of the tower body 1, and a circulating water pump 9 is installed inside the outer chamber 8, and the circulating water pump 9 is communicated with the water inlet pipe 6;

[0019] Furthermore, after the liquid sprayed by the spray pipe 5 cools down the exhaust gas, it will fall to the bottom of the inner cavity of the tower body 1. The outer chamber 8 is connected to the inner cavity of the tower body 1. The water at the bottom of the inner cavity of the tower body 1 can be circulated to the water inlet pipe 6 through the circulating water pump 9, and re-transported to the spray pipe 5, and sprayed inside the tower body 1, thereby realizing the circulation of the spray water and achieving the effect of saving water.

[0020] The first filling assembly includes a first filling frame 10 fixed on the inner wall of the tower body 1 and a circular filling plate 11 installed on the first filling frame 10, and the first filling assembly includes a second filling frame 12 fixed on the inner wall of the tower body 1 and a semicircular filling plate 1311 installed on the second filling frame 12;
