Description

High-efficiency demister for steam-water separator

Technical Field

The utility model belongs to demister equipment field, concretely relates to high-efficient demister is used to catch water.

Background

The demister in the steam-water separation tower is used for separating liquid drops carried by gas and removing mist from the gas so as to ensure the mass transfer efficiency, can effectively remove the mist drops with the diameter of 3-5 mu m, and if the demister is arranged between tower trays, the mass transfer efficiency of the tower trays can be ensured, and the plate spacing can be reduced. When mist is contained in the gas, the purity of the gas is reduced, the gas enters a downstream device, the quality of products in the downstream device is affected, and the gas is discharged into the atmosphere to cause atmospheric pollution.

The demister commonly used at present is a screen demister, the processing of screens is complex, the screens are generally required to be customized, the production cost can be increased by using a large amount of screens, and the conventional single-density screen demister often causes that small liquid drops cannot be removed when the gas phase speed in a separation tank is high, or the flow of feed liquid phase is high or the diameter of the liquid drops in feed is small, or the reduced liquid phase removed in the tank is secondarily entrained by the gas phase, and the demister can be flooded when the gas phase is serious, so that the gas-liquid separation efficiency is very low, and the normal production of the most downstream of the product quality is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a steam-water separator is with high-efficient demister can high-efficiently get rid of the foam in the gas, has avoided the liquid phase to add the problem in area by gaseous secondary simultaneously, simple structure, low cost.

The utility model discloses a realize through following technical scheme:

the utility model provides a high-efficient demister for catch water, sets up in catch water, includes sieve and guiding gutter, the guiding gutter set up the lower surface at the sieve, the both ends of guiding gutter are equipped with the clearance with catch water's inner wall be equipped with a plurality of air guide holes on the sieve, be equipped with the crossbeam in the air guide hole the vertical defoaming thorn that is equipped with on the crossbeam.

Further preferably, the guide groove is a V-shaped groove, and the angle between the guide groove and the axial direction of the steam-water separator is 60-90 degrees. The contact of the liquid and the gas that can avoid the whereabouts avoids gaseous gathering secondary to smuggle the liquid drop secretly, and the guiding gutter tilting sets up, can be with the faster outflow of the liquid in the inslot. And the gas can collide with the outer wall of the diversion trench in the rising process, so that the fog drops in the gas can be further removed.

Further preferably, the diameter of the air guide hole is 4-8 mm.

Further preferably, a plurality of fixing lugs are uniformly distributed on the outer side of the sieve plate.

Further preferably, the cross beams are arranged in a groined shape, and the holes between the cross beams can further remove fog drops in the gas.

Further preferably, the defoaming thorn comprises a main thorn, an auxiliary thorn is arranged at the upper end of the main thorn, and the angle between the auxiliary thorn and the main thorn is 30-90 degrees. Can effectively break up the fog drops in the gas.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses a set up in the air vent of sieve and remove last thorn, can effectually smash the droplet in the gas, reach the high efficiency and remove the foam.

2. The utility model discloses a set up the guiding gutter, can further get rid of the droplet in the gas, liquid in the guiding gutter flows down along catch water's inner wall simultaneously, has avoided the orbit that gaseous rises, can avoid in the gas secondary to add and take the liquid droplet.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1-3, the high-efficiency demister for the steam-water separator is arranged in the steam-water separator 1 and comprises a sieve plate 2 and a diversion trench 3, wherein the diversion trench 3 is arranged on the lower surface of the sieve plate 2, gaps are arranged between two ends of the diversion trench 3 and the inner wall of the steam-water separator 1, a plurality of air guide holes 6 which are uniformly distributed are arranged on the sieve plate 2, a cross beam 5 is arranged in each air guide hole 6, and defoaming spines 7 are vertically arranged on the cross beam 5.

The diversion trench 3 is a V-shaped trench, and the angle between the diversion trench and the axis direction of the steam-water separator 1 is 90 degrees.

The diameter of the air guide hole 6 is 5 mm.

The outside of the sieve plate 2 is provided with 6 fixing lugs 4 which are evenly distributed.

The cross beam 5 is arranged in a groined shape.

The defoaming thorn 7 comprises a main thorn 9, auxiliary thorns 8 which are uniformly distributed are arranged at the upper end of the main thorn 9, and the angle between the auxiliary thorns 8 and the main thorn 9 is 30 degrees.

During operation, when gas in the catch water 1 rises to guiding gutter 3, collide with the outer wall of guiding gutter 3, part droplet in the gas can fall along the outer wall of guiding gutter 3, when gas rises to sieve 2, earlier through defoaming thorn 7, after main thorn 9 and vice thorn 8, droplet in the gas is all smashed, it flows down along catch water 1's inner wall in guiding gutter 3 to instil into, the gas after the defoaming discharges after the hole between # -shaped crossbeam 5, the hole between crossbeam 5 can further detach droplet in the gas, make the gas more pure.

Of course, the above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the embodiments of the present invention. The present invention is not limited to the above examples, and the technical field of the present invention is equivalent to the changes and improvements made in the actual range of the present invention, which should be attributed to the patent coverage of the present invention.
