Abstract
The utility model discloses a stripping tower which comprises a vertical cylindrical stripping tower, wherein a gas outlet formed in the top of the stripping tower, a liquid outlet formed in the bottom of the stripping tower, a tower and a heating circulating pipe arranged at the lower end of the gas outlet. A demister connected with the heating circulating pipe is a uniformly distributed net structure and the bore diameter is 1-3cm. A water inlet pipeline is formed at the lower end of the demister and extends into the central position of the stripping tower. The orifice of the water inlet pipeline downward is just opposite to a distributor, 5-8 corrugated packing is distributed on the lower part of the distributor, and the distance from the distributor to the corrugated packing is 50-110cm. A tray is arranged on the lower part of the corrugated packing, a flow collecting plate is arranged on the tray, a steam pipeline is installed between the flow collecting plate and the bottom liquid outlet, and the distance from the flow collecting plate and the bottom liquid outlet is 100-300cm. The stripping tower disclosed by the utility model has the characteristics that the distributor in the stripping tower adopts straight pipes which are uniformly distributed, so that industrial wastewater fully and uniformly flows into the corrugated packing, and therefore, the contact area with steam is great, COD is fully evaporated, and the removal rate of COD reaches up to over 50%, thereby greatly lowering the demand of use level of primary water.
Description
Affiliated technical field
The utility model relates to the pretreated device of a kind of processing wastewater, is the stripping tower of a kind of COD of removal.
Background technology
At present, the high-concentration waste water intractability that neopentyl glycol industry produces is larger, and common processing scheme is with a large amount of water dilutions, and then carries out biochemical treatment, can expend so a large amount of water resourcess, is unfavorable for environmental protection.
Summary of the invention
The purpose of this utility model is to provide a kind of dilute with water that reduces, and removes the stripping tower of COD in waste water.
The purpose of this utility model is achieved through the following technical solutions: this stripping tower comprises vertical type cylinder type stripping tower, the top of stripping tower is provided with pneumatic outlet and bottom liquid outlet, the heating cycle pipe of hand hole and pneumatic outlet lower end, the scum dredger being connected with heating cycle pipe is that be evenly distributed reticulated structure and aperture of one is 1-3cm Despumation device, scum dredger lower end is provided with inlet channel, inlet channel stretches into the central position of stripping tower, the mouth of pipe of inlet channel is down just to sparger, the lower disposed of sparger has 5-8 layer ripple packing, and sparger and ripple packing distance are 50-110cm, the bottom of ripple packing is provided with tower tray, on tower tray, be provided with conflux plate, between conflux plate and bottom liquid outlet, steam-pipe is installed, distance between conflux plate and bottom liquid outlet is 100-300cm, sparger is to be evenly distributed on ripple packing entering Stripper liquid, sparger is by dividing plate, multiple straight tubes, water service pipe (forms, straight tube is vertically through dividing plate, and the upper and lower straight tube distance of dividing plate equates, the quantity of straight tube is 30-50, be evenly distributed on dividing plate, the straight tube top seal of upper end and have symmetrical U-shaped groove, the degree of depth of groove is less than 1/3rd of length of straight pipe, the quantity of water service pipe quantity and straight tube equates.
The utility model feature is that the sparger in stripping tower takes straight tube to be uniformly distributed, make on the full and uniform inflow ripple packing of trade effluent, make itself and steam contact surface larger, COD fully vaporizes, the clearance of COD index, up to more than 50%, greatly reduces the consumption demand to a water.
