Abstract

A degasser includes a body (1) and a board (2) with a baffle (3). An overflow channel (4) would be formed between the baffle (3) and the inside wall of the body. Two adjacent overflow channels (4) are misplaced. An aeration drainage pipe (5) with aeration holes (6) is arranged on the board (2). Corresponding to a gas outlet, the aeration holes (6) are opened lower than the baffle (3). The aeration drainage pipe (5) and the gas outlet corresponding to the board separately are connected to the gas inlet pipe (7) and the gas outlet pipe (8) in parallel. The degasser is especially applicable to the ammoniacal nitrogen deprivation from the ammonia nitrogen waste-water with high consistency after treatment such as chemical combination of nitrogen, sulfur and cyanogen. The degasser is characterized in the simple structure, large mass area, high degasifying efficiency, small inner resistance, which can be used in the plain blower fan.

Description

A kind of degassing tower

One, technical field

The utility model relates to a kind of chemical industry equipment, the tower that particularly a kind of gas-liquid mass transferring is used, specifically a kind of degassing tower that removes escaping gas in the liquid.

Two, background technology

The tower that relates to gas-liquid mass transferring at present in the chemical process mainly contains packed tower, sieve-plate tower, bubble column, valve tower etc., is used for distillation or rectifying and realizes separating.Remove in the liquid escaping gas and use aeration usually, promptly blast air or other inert gases in liquid, at this moment above-mentioned tower is big because of internal resistance, pressure drop is fast, even if use the higher roots blower of pressure head also not satisfy requirement sometimes.ZL200420026199.7 discloses a kind of denitrifying tank, is used for removing the ammoniacal nitrogen in the waste water, and just by the porous tracheae institute aeration every logical sequence bottom, the ammoniacal nitrogen after flowing out denitrifying tank in it makes and is removed each in waste water is flowed through denitrifying tank successively when logical sequence.Denitrifying tank is simple in structure, but efficient is low, and ammoniacal nitrogen can not reclaim.

Three, summary of the invention

The purpose of this utility model provides a kind of degassing tower, and technical problem to be solved is to reduce the tower internal resistance and reclaim the gas that is removed.

The technical solution of the utility model comprises tower body and is fixed on the interior several layers column plate of tower body, on tower body letter wall, have gas import and export and liquid import and export, with the fundamental difference of existing various towers be, plate washer is all arranged on every layer of column plate, and the effect of plate washer is to make liquid holdup on column plate and by aeration; Constitute overflow ducts between plate washer and the tower body inwall, adjacent two overflow ducts dislocation is put, and the liquid that the last layer column plate is overflowed drops on down on one deck column plate; Be provided with the aeration comb on every layer of column plate, the aeration comb is connected with gas feed, and is lower than plate washer and to a gas outlet should be arranged; On the aeration comb solarization air cap is arranged, the aeration comb is lower than plate washer, in its liquid that is detained that just submerges fully, to enlarge mass transfer area, improves aeration efficient, and a corresponding gas outlet to be to reduce air resistance in the tower, prevents that foam from assembling in tower; Air inlet corresponding with the number of plates and gas outlet are connected in parallel on the inlet manifold respectively and give vent to anger on the house steward.

Inlet manifold's one end is useful on the evacuated tube of emptying, and the other end is connected with air compressor machine or blower fan, sends into air or other inert gases with aeration in tower.

Giving vent to anger also has evacuated tube on the house steward, also has recovery tube, evacuated tube to be used for emptying simultaneously; Recovery tube is connected with tourie, and tourie is connected with air exhauster, to reclaim useful gas.

When adjacent two overflow ducts dislocation, 180 degree were put, then air inlet and gas outlet can be separately positioned on two buses of tower body barrel.

Be distributed with through hole on the every arm of aeration comb, promptly solarization air cap can weld a short tube on solarization air cap, to increase the flow velocity of air-flow.

On the tower body barrel, can also have the steam-gas inlet of using for steam heated, when environment temperature is lower, when being unfavorable for that processed liquid is realized gas-liquid separation, can be in tower heat temperature raising.

This degassing tower is work like this.Liquid enters in the tower from tower body top, at first drops on the ground floor column plate, is detained and by aeration, falls on the second layer column plate from overflow ducts then, be detained, aeration again, and the like until last one deck column plate.The gas that removes enters the house steward that gives vent to anger from the gas outlet, or emptying or recovery.Remove liquid behind the escaping gas from tower bottom by carrying-off.

This degassing tower is applicable to and removes volatile gas in the liquid, as gases such as the nitrogen of chemical combination attitude, sulphur, cyanogen.Be particularly suitable for removing the ammoniacal nitrogen in the high-concentration ammonia nitrogenous wastewater after the processing, it is simple in structure, and mass transfer area is big, the degassing efficiency height, and internal resistance is little, and common blower fan is just applicable.

Four, description of drawings

Fig. 1 is the structural representation of this degassing tower.Column plate and the mutual position of aeration comb in Fig. 1 a signal tower body, the position that illustrates air inlet, gas outlet on the tower body barrel simultaneously with and and inlet manifold and the relation between the house steward of giving vent to anger; Fig. 1 b illustrates two overflow ducts 180 to spend the steam-gas inlet and the liquid-inlet of dislocation storing and tower body barrel.

Fig. 2 is the tower plate structure schematic diagram.

Five, the specific embodiment

In conjunction with the accompanying drawings, be material with general steel plate and water gas pipe, non-limiting examples is described below.

As shown in Figure 1, processing tower body 1, internal diameter Φ 600mm, ellipse head has evacuation port on it, and the circular cone back cover has draining, slag-drip opening on it.As shown in Figure 1a, have ten air inlets on a bus of tower body 1 barrel, have ten gas outlets on another bus of basic symmetry, air inlet and gas outlet are connected in parallel on respectively on the inlet manifold 7 and the house steward 8 that gives vent to anger by short tube and valve separately.There is evacuation port inlet manifold 7 upper ends, and the other end is connected in the outlet of air compressor machine; There is evacuation port house steward 8 upper ends of giving vent to anger, and the other end has and reclaims mouthful, is connected with retracting device by recovery tube.Shown in Fig. 1 b, on the tower body barrel, also have steam-gas inlet 9 and the liquid-inlet 10 used for steam heated.

Ten layers of column plate 2 of welding in tower body 1, floor height 300mm.Tower plate structure has the plate washer 3 of high 150mm as shown in Figure 2 on it.Shown in Fig. 1 b, form overflow ducts 4, overflow ducts 4 the widest part 50mm between plate washer 3 and the tower body inwall.Two adjacent overflow ducts 4 dislocation 180 degree are put.
