Packing tower for industrial waste gas treatment

Abstract

The invention discloses a packing tower for industrial waste gas treatment. The packing tower comprises a packing tower body, wherein a heat exchanger is mounted on a gas inlet pipe, a liquid discharge pipe is arranged at the lower side of the packing tower body, a collecting box is mounted at one end of the liquid discharge pipe, an exhaust pipe is welded to the upper side of the packing tower body, a dehumidifying box is mounted on the exhaust pipe, an active carbon filtering layer is mounted in the dehumidifying box, a liquid inlet pipe penetrates through one side of the packing tower body,one end, positioned at the packing tower, of the liquid inlet pipe is provided with a nozzle, a baffle plate is welded to the internal bottom side of the packing tower body, the baffle plate is welded with a guide rod, a swash plate penetrates through the guide rod, two support grid plates are mounted on the inner wall of the packing tower body, packing is arranged between the support grid plates, and an anti-wall-flow ring is mounted at the internal upper side of the packing tower body and comprises a chassis, a gas vent, a diversion trench and a through hole. The heat exchanger is a plate type heat exchanger, so that heat energy in waste gas can be well utilized, and energy saving and environmental protection are realized.

Description

technical field [0001] The invention relates to the field of packed towers, in particular to a packed tower for industrial waste gas treatment. Background technique [0002] Packed tower is an important equipment for waste gas treatment in industry. There are many defects in the existing packed tower, such as the inability to make good use of the heat energy in the waste gas, not being energy-saving and environmentally friendly, and prone to wall flow, which leads to uneven distribution of liquid in the packing. , the water vapor in the gas cannot be removed well, and the used liquid is discharged arbitrarily to pollute the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide a packed tower for industrial waste gas treatment to solve the problems in the above-mentioned background technology, such as insufficient energy saving and environmental protection, easy oc...
