Abstract
The invention discloses a stripping tower for removing COD, which comprises a vertical cylindrical stripping tower; a gas outlet is disposed at the top of the stripping tower; a bottom liquid outlet and a hand hole are disposed at the lower part of the stripping tower; a heating circulating pipe is disposed below the gas outlet; a defoamer connected with the heating circulating pipe is a defoaming device with a uniformly distributed net structure and a pore size of 1-3 cm; a water inlet pipeline is disposed below the defoamer and extends to the central position of the stripping tower; the pipe orifice of the water inlet pipeline faces downwards and directly faces a distributor; 5-8 layers of corrugated fillers are arranged at the lower part of the distributor; the distance between the distributor and the corrugated fillers is 50-110 cm; a tower tray is disposed below the corrugated fillers; a flow converging plate is disposed on the tower tray; a steam pipeline is mounted between the flow converging plate and the bottom liquid outlet; the distance between the flow converging plate and the bottom liquid outlet is 100-300 cm. The invention is characterized in that the distributor in the stripping tower is in straight pipe uniform distribution, so that industrial waste water can fully and uniformly flow to the corrugated fillers, which increases the contact area with steam, realizes complete vaporization of COD, reaches a removal rate of COD index of up to more than 50%, and greatly reduces the demand on the using amount of primary water.
Description
Affiliated technical field
The present invention 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 object of the present invention is to provide a kind of dilute with water that reduces, remove the stripping tower of COD in waste water.
Object of the present invention 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.
Feature of the present invention 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.
