Description

Technical Field

[0001] The utility model relates to the technical field of packed towers, in particular to spraying equipment used for packed towers. Background Art

[0002] At present, in the field of environment and environmental engineering, according to the structural form of the gas-liquid contact parts in the absorption tower, the absorption tower can be divided into a packed tower and a plate tower. Among them, the packed tower belongs to the differential contact countercurrent operation, and the packing is used as the basic component of the gas-liquid contact in the tower. The tower body is connected by several sections of cylinders. The tower body can be made of carbon steel, ceramics, plastics, and glass according to the properties of the materials to be processed. The body is filled with a certain height of packing, and a packing support plate is installed below the packing. The packing pressure net is above the packing. When the packing layer height is too high, it can be filled in several sections, and a liquid redistribution device is installed between the two sections. The packed tower is generally operated according to the gas-liquid countercurrent. The mixed gas enters the tower body from the gas inlet at the bottom of the tower, passes through the packing layer from bottom to top, and is finally discharged from the gas outlet at the top of the tower. The absorbent passes through the liquid distributor from the top of the tower, is evenly sprayed into the packing layer, flows downward along the surface of the packing layer, and is discharged from the tower at the bottom of the tower through the pipe mouth. Due to the continuous contact between the rising airflow and the descending absorbent in the packing layer, the concentration of the solute in the rising airflow becomes lower and lower, and when it reaches the top of the tower, it reaches the absorption requirement and is discharged from the tower. On the contrary, the solute concentration in the descending liquid becomes higher and higher, and when it reaches the bottom of the tower, it reaches the process requirements and is discharged from the tower.

[0003] At present, improper design of the auxiliary structure inside the packed tower causes uneven distribution of gas and liquid in the packing layer on the top of the partition, seriously affecting the mass transfer effect. The excessive resistance of the auxiliary structure reduces the production capacity of the tower. Utility Model Content

A diversion plate 2202 is fixedly connected to the bottom of the slow flow arc block 2203. A diversion groove 2204 is opened in the top of the diversion plate 2202.

[0035] Furthermore: the guide rod 2201 guides the water column falling in the liquid outlet pipe 2103, which increases the stability of the falling water, so that it can accurately impact the top of the slow-flow arc block 2203 to complete the diversion of the water, so that the falling water can be evenly distributed in the packing tower body 3, thereby improving the contact between the water and the flue gas and increasing the filtering effect.

[0036] In actual operation, when the device is used, the flue gas enters the bottom of the packing tower body 3 through the air inlet pipe 31 and flows upward. In the process of the flue gas flowing upward, if the top of the grid plate 1204 is blocked, the flue gas can directly pass through the air holes 1502 opened on the surface of the riser 1501 through the grid plate 1204 and enter the packing layer, and contact with the moisture in the packing layer to complete the filtering of the flue gas.

[0037] When the water falls through the liquid outlet pipe 2103, it is guided by the guide rod 2201 to impact the top of the slow-flow arc block 2203.
