Description

Novel stripping tower

Technical Field

The invention relates to the technical field of sewage treatment, in particular to a novel stripping tower.

Background

The COD content in the polyester wastewater in the plastic product industry is higher and does not meet the emission standard, the COD content in the wastewater needs to be reduced, a stripping tower device is generally adopted for wastewater treatment, and the steam is utilized to vaporize organic matters in the wastewater through heat and mass exchange, so that the COD content in the wastewater is reduced.

The common stripping tower mostly adopts fixed multistage column plates, sewage enters from the upper part of the stripping tower and sequentially flows through each stage of column plates, then organic matters in the wastewater are vaporized and taken away by steam, the COD content of the sewage is reduced, and the fixed column plates are inconvenient to clean.

Preferably, every two adjacent layers of trays 7 are arranged in a staggered manner in the circumferential direction.

The novel stripping tower provided by the invention has the following advantages:

1. By additionally arranging the tower plates, when sewage falls on the rotating tower plates, the sewage can be dispersed into finer particles under the action of centrifugal force, so that the contact area with steam is increased, the steam utilization rate is improved, a better heat and mass exchange effect is achieved, and the sewage treatment capacity is enhanced.

2. The column plate of the invention can be conveniently disassembled and cleaned.

The foregoing description is only an overview of the present invention, and may be implemented according to the content of the specification for better understanding of the technical means of the present invention, and for better understanding of the above and other objects, features and advantages of the present invention, the following detailed description of the preferred embodiments is given by way of example only, together with the accompanying drawings, in which:

[ Main element symbols description ]

The device comprises a 1-tower cover, a 2-tower body, a 3-steam input pipe, a 4-water pump, a 5-sewage pipe, 6-sewage, 7-tower plates, 71-blades, 72-through holes, 8-tower plate shafts, 9-couplings, 10-motors, 11-stripping steam pipes, 12-liquid inlet pipes and 13-liquid outlets.

Detailed Description

In order to further describe the technical means and effects adopted by the present invention for achieving the preset purpose, the following detailed description refers to the specific implementation, structure, characteristics and effects of a novel stripping tower according to the present invention with reference to the accompanying drawings and preferred examples.

Referring to fig. 1 to 3, a novel stripping tower comprises a vertical cylindrical tower body 2 provided with a tower cover 1, wherein the tower cover 1 and the tower body 2 are fixed through bolts, a stripping steam pipe 11 and a motor 10 are arranged on the tower cover 1, an output shaft of the motor 10 is connected with a tower plate shaft 8 through a coupler 9, a plurality of layers of tower plates 7 are arranged on the tower plate shaft 8, every two adjacent layers of tower plates 7 are arranged in a staggered manner along the circumferential direction, the tower plates 7 rotate along with the rotation of the tower plate shaft 8, each tower plate 7 comprises a plurality of blades 71 uniformly distributed along the circumferential direction, a plurality of through holes 72 are formed in each blade 71, the through holes 72 are convenient for steam to pass through from bottom to top, so that the gasification efficiency is improved, in operation, the motor 10 drives the tower plates 7 to rotate through the tower plate shaft 8, when sewage falls onto the tower plates 7, the effect of centrifugal force can enable the sewage to be dispersed into finer particles, so that the contact area with the steam is increased, the steam utilization rate is improved, a better heat mass exchange effect is achieved, and the water drops from the through holes 72 of the blades of the second layer of the tower plates and the blades of the third layer of the tower plates are scattered;

The tower body 2 below still is equipped with steam input pipe 3, feed liquor pipe 12, be located the liquid outlet 13 of tower body 2 bottom and install the sewer pipe 5 of water pump 4, steam input pipe 3 installs in one side of tower body 2 and is located the below of column plate 7, the one end of sewer pipe 5 is installed in the bottom of tower body 2 and is buckled towards tower body 2 bottom, the other end passes tower lid 1 and installs in the top of tower body 2, sewer pipe 5 can be with the sewage pump in the tower body 1 to tower body 2 top under the drive of water pump 4 to from tower body 2 top blowout.
