Abstract

The utility model discloses a kind of demister guide shell, swirl vane group is installed at its air inlet, barrel is provided with permeable structure, it is characterized in that, the cylinder of described guide shell includes one section of tapered conically shaped, the gas outlet of described tapered conically shaped is connected with the conically shaped of one section of flaring, and tapered conical cylinder is 5~10 with the height ratio of flaring conically shaped, and the height of tapered conical cylinder is 4~10 with the ratio of tapered conical cylinder air inlet basal diameter.Be entrained with the flue gas of drop by the swirl vane group of guide shell porch after, enter the cylinder of guide shell rotating fluidised form, under centrifugal action, major part drop is thrown toward guide shell barrel, discharges through permeable structure.At guide shell converging transition, flue gas gas speed is continuously increased, and flue gas carries the drop not separated and enters divergent segment, and after gas prompt drop is low, drop is separated once again, thus can reduce escape droplet amount, optimizes separating effect.

Description

Demister guide shell
Technical field
This utility model relates to the gas-liquid separation device in chemical field, is specially a kind of demister guide shell.
Background technology
The patent application of Application No. 201510897113.0 discloses a kind of Novel defroster, utilizes swirl vane group to make Gas produces and rotates fluidised form, and under centrifugal action, the drop in gas is thrown toward guide shell barrel, is collected through after guide shell Fluid cylinder is collected, and wherein guide shell can be straight tube, tapered cone cylinder or the combination of the two.Flue gas flowing in tapered cylinder, Air velocity and the airflow direction of change contribute to drop and separate with gas, but along with gas speed is continuously increased, also have part gas Know from experience and cause partial drop to be escaped in exit because flow velocity is too fast through tapered cylinder, affect separating effect.
Summary of the invention
Technical purpose of the present utility model is on the basis of existing technology, it is provided that the demister guide shell of a kind of improvement, To solve problems of the prior art.
For realizing above-mentioned technical purpose, technical scheme disclosed by the invention is:
A kind of demister guide shell, is provided with swirl vane group at its air inlet, barrel is provided with permeable structure, its feature Being, the cylinder of described guide shell includes one section of tapered conically shaped, the gas outlet of described tapered conically shaped and one section of flaring Conically shaped linking, the height ratio of tapered conical cylinder and flaring conically shaped is 5~10, the height of tapered conical cylinder and tapered cone The ratio of shape cylinder air inlet basal diameter is 4~10.
As preferably, the axis of described tapered conical cylinder and flaring conically shaped is arranged on the same line.
Beneficial effect:
Be entrained with the flue gas of drop by the swirl vane group of guide shell porch after, enter guide shell rotating fluidised form Cylinder, under centrifugal action, major part drop is thrown toward guide shell barrel, discharges through permeable structure.At guide shell converging transition, Flue gas gas speed is continuously increased, and flue gas carries the drop not separated and enters divergent segment, and after gas prompt drop is low, drop is separated once again, Thus escape droplet amount can be reduced, optimize separating effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to be further elucidated with the technical solution of the utility model and technique effect, below in conjunction with the accompanying drawings and specific embodiment This utility model is described further.
As it is shown in figure 1, a kind of demister guide shell, swirl vane group 1(spiral board is installed at its air inlet), described in lead The cylinder of flow cartridge includes one section of tapered conically shaped 2 and the conically shaped 3 of one section of flaring.Tapered conical cylinder 2 gas outlet is bored with flaring Shape cylinder 3 is connected, and the axis of two conically shapeds on the same line, and is equipped with permeable structure on the barrel of two conically shapeds, as thoroughly Water gap or permeable nethike embrane etc..The outside of described guide shell is provided with liquid cylinder (not shown), and the liquid of diversed cylinder trapping passes Collected by liquid cylinder after permeable structure, can be discharged by drainage system.
In the present embodiment, the height of flaring type conically shaped 3 be less than gradual shrinkage conically shaped 2, tapered conical cylinder 2 height h1 with gradually The ratio range of the height h2 expanding conically shaped 3 is 5~10.Tapered conical cylinder 2 air inlet diameter is less than its height, and its height h1 is 4~10 times of air inlet basal diameter d.To the demister guide shell after structure parameter optimizing and existing demister guide shell phase Ratio, can be effectively improved the effect of gas-liquid separation.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.One's own profession Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also Having various changes and modifications, this utility model claims scope by appending claims, description and equivalent thereof Define.
