Abstract
The invention discloses a demister comprising a housing (1). A mixed gas inlet port (2), a gas outlet port (3) and a liquid outlet port (4) are arranged on the housing (1). A bearing device is arranged in the housing (1). At least one set of fixing rack (5) is arranged on the bearing device. At least one screen block (6) is arranged on the fixing rack (6). The fixing rank (5) and the screen block (6) are movably connected. According to the invention, the amount of mounted screen blocks can be determined according to filtering requirements, such that a gas-liquid separation purpose can be achieved. Also, the fixing rack and the screen block are movably connected. The screen block can be detached, such that mounting and cleaning can be easily carried out by a user.
Description
Technical field
The present invention relates to chemical industry equipment field, particularly a kind of demister.
Background technology
In the production process of chemical field, too in most cases must carry out filtering to the liquid (mist) of folder doping in gas, thereby reduce the corrosion to equipment and avoid environment.
Within several years, domestic patent database discloses some relevant demister patented technologies:
For example [title] a kind of demister, [notification number] CN201701787U, this disclosure of the invention a kind of demister, it belongs to a kind of chemical industry equipment.When it has solved in prior art the reaction of esterification process synthesis for ethyl acetate, the defect that is easy to cause the corrosion of rectifying column tower body and increases the weight of rectifying column burden, it comprises housing, top, middle part and the bottom of housing are respectively equipped with gas vent, synthesis gas entrance and liquid outlet, on gas vent, synthesis gas entrance and liquid outlet, are respectively equipped with upper flange, middle flange and lower flange; The top of enclosure interior is provided with spiral board; Described spiral board comprises gear cylinder, and gear cylinder inner side is provided with blade, and outside is evenly distributed with distribution rings.The present invention is mainly used in the gas-liquid separation in the course of reaction of esterification process synthesis for ethyl acetate.But, when this invention work, may cause liquid upwards to throw away, can not effectively reach the object of filtering liquid (mist).
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, and a kind of demister is provided, and by filtering demand, increases and decreases neatly silk screen piece, effectively improves foam removal efficiency.
To achieve these goals, the technical scheme that patent of the present invention adopts:
A kind of demister, comprises housing, is respectively equipped with gaseous mixture entrance, gas vent and liquid outlet on described housing, is also provided with supporting arrangement in described housing, and described supporting arrangement is provided with fixed mount, and silk screen piece is installed on described fixed mount.
Further illustrate as of the present invention, its mesh number of described silk screen piece is 0.5 ~ 10 order.When the mesh number of silk screen piece is 2 ~ 3 order in the present invention, under this mesh said conditions, when mist is stained with on silk screen piece, very easily form water film, and moisture film is under this big or small area time, tension force is very easily damaged, cause it to turn to rapidly water droplet, mist is eliminated, the foam device best results of demister.
Further illustrate at least one group of described fixed mount, at least one of described silk screen piece as of the present invention.
Further illustrate as of the present invention, described fixed mount is flexibly connected with silk screen piece.Connected mode is that spiral connects.
Further illustrate as of the present invention, it is polytetrafluoroethylene (PTFE) that described silk screen piece adopts material.
When the gas with mist enters in housing from gaseous mixture entrance, while rising by silk screen piece with certain speed, due to the effect of inertia that mist rises, mist and silk screen piece collide and are attached on silk screen surface.The gravitational settling of the diffusion of mist, mist on fine-structure mesh surface, makes the larger drop of mist formation flow to the interface point of two rhizoids along fine-structure mesh.The capillarity of the wettability of fine-structure mesh, the surface tension of liquid and filament, make drop increasing, until the gravity that the drop of assembling produces to himself greatly exceed the climbing power of gas and surface tension of liquid with joint efforts time, drop just separates from filament, discharge from liquid outlet, and discharge from gas vent through the gas filtering.
Beneficial effect of the present invention:
The present invention's volume simple in structure is little, and foam removal efficiency is high, and silk screen piece is detachable, is easy to user installation, operation, maintenance and cleaning; The material of silk screen piece employing is simultaneously polytetrafluoroethylene (PTFE), makes silk screen piece corrosion-proof high-temp, extends working time, cost-saving.The quantity that this demister is installed silk screen piece according to filtering demand reaches gas-liquid separation object, and fixed mount is flexibly connected with silk screen piece simultaneously, and silk screen piece is detachable, is convenient to user installation and uses and clean.

body embodiment
Below in conjunction with drawings and Examples, the present invention is further described, but protection scope of the present invention is not only confined to following examples.
Embodiment 1
In the present embodiment, as shown in Figure 1, comprise housing 1, on described housing 1, be respectively equipped with gaseous mixture entrance 2, gas vent 3 and liquid outlet 4, in described housing 1, be also provided with supporting arrangement, described supporting arrangement is provided with fixed mount 5, and silk screen piece 6 is installed on fixed mount 5; Its mesh number of silk screen piece is 2 ~ 3 orders; Fixed mount 5 is one group, and described silk screen piece 6 quantity are one; Described fixed mount 5 is flexibly connected with silk screen piece 6.It is polytetrafluoroethylene (PTFE) that described silk screen piece 6 adopts material.
When the gas with mist enters in housing 1 from gaseous mixture entrance 2, while rising by silk screen piece 6 with certain speed, due to the effect of inertia that mist rises, mist and silk screen piece 6 collide and are attached on silk screen surface.The gravitational settling of the diffusion of mist, mist on fine-structure mesh surface, makes the larger drop of mist formation flow to the interface point of two rhizoids along fine-structure mesh.The capillarity of the wettability of fine-structure mesh, the surface tension of liquid and filament, make drop increasing, until the gravity that the drop of assembling produces to himself greatly exceed the climbing power of gas and surface tension of liquid with joint efforts time, drop just separates from filament, discharge from liquid outlet 4, and discharge from gas vent 3 through the gas filtering.
Embodiment 2
The present embodiment difference from Example 1 is: as shown in Figure 2, its mesh number of silk screen piece is 0.5 ~ 1 order, and described fixed mount 5 is one group, and described silk screen piece 6 has two, all the other structures are identical with embodiment 1, and the present embodiment equipment has effectively increased foam removal efficiency in application process.
Embodiment 3
The present embodiment difference from Example 1 is: its mesh number of silk screen piece is 9 ~ 10 orders, described fixed mount 5 is two groups, on every group of fixed mount, silk screen piece 6 has one, its position is interleaved up and down, all the other structures are identical with embodiment 1, and the present embodiment equipment has effectively increased foam removal efficiency in application process.
