Abstract

The utility model relates to a cyclone demister exhausting gas down that is used for gas-liquid separation or dedusting. The demister comprises a volute provided with a gas inlet, wherein the volute is connected with a liquid collecting barrel body; a bottom plate of the liquid collecting barrel body is provided with a liquid discharge pipe; the liquid collecting barrel body is internally provided with an exhaust pipe; and the lower end of the exhaust pipe, with the outlet downward, extends out of the liquid collecting barrel body. The demister realizes gas-liquid separation by virtue of centrifugal action, the circulation area of gas is very large and resistance loss is little. When used for smoke demisting in a desulfurizer, the demister can effectively solve the problems of scaling and blocking, and does not need water rinsing, thus reducing the device investment and operating cost.

Description

A kind of downward air discharge cyclone demister

Technical field

The utility model relates to a kind of downward air discharge cyclone demister that is used for gas-liquid separation.

Background technology

In the process for flue gas desulfurization by limestone/lime-gypsum wet device, flue gas is continuous and absorbent reaction generation calcium sulfite and crystal of calcium sulfate thing in the absorption tower, cause the rising flue gas after the desulfurization to be entrained with the spray film that contains the solid suspension thing in a large number, flue gas must separate through demister before discharging remove the liquid mist.The demister that adopts mostly is silk screen or deflection plate at present, and the liquid mist of deviating from causes silk screen or deflection plate fouling to stop up easily, therefore need on-line cleaning, also require when fouling is serious to stop transport and clean, not only expend a large amount of flushing waters, the breaking plant water balance, and a large amount of flooding nozzles and pipeline cause investment and operating cost to increase.

The utility model content

The purpose of this utility model is to provide a kind of downward air discharge cyclone demister, overcomes the existing easy fouling blocking problem of demister.

The downward air discharge cyclone demister comprises the spiral case that is provided with the gas access, and spiral case is connected with the liquid collecting cylindrical shell, and the liquid collecting cylinder bottom plate is provided with discharging tube, in the liquid collecting cylindrical shell blast pipe is housed, and the liquid collecting cylindrical shell is stretched out in the blast pipe lower end, and outlet downwards.

Said cylindrical shell top is provided with the cylindric guide shell coaxial with blast pipe.

The spinning disk of circumference arranged askew is set between said guide shell and the following blast pipe.

5~65 ° of angles of said liquid collecting cylinder bottom plate inclination, discharging tube is located at the lowest order of base plate.

Said liquid collecting cylinder bottom plate banking.

Said liquid collecting cylinder bottom plate therefrom mind-set both sides tilts.

The therefrom polygon inclination of mind-set of said liquid collecting cylinder bottom plate.

Said spiral case gas access is a rectangle, and the short transverse length dimension of rectangle entrance is 2~3 times of horizontal direction width.

Contain liquid fog body and enter that the mode with rotation at a high speed flows into the liquid collecting cylindrical shell behind this cyclone demister spiral case, because of centrifugal action, the liquid mist moves radially and forms liquid film to cylinder inboard wall, and liquid film flows downward and compiles the back at base plate and discharge from the lower discharging tube; Gas after the demist is discharged by the following blast pipe that stretches into the cylindrical shell certain depth.

In sum, centrifugal action when this cyclone demister contains the rotation of fog height speed by making realizes gas-liquid separation, gas flow area is very big, drag losses is little, be used for the flue gas demist of desulfurizer, can effectively solve the fouling blocking problem, needn't flushing water, reduced plant investment and operating cost.Owing to be horizontal air inlet, bottom exhaust, can reduce the length and the elbow of flue during installation, make desulfurizer drag overall loss lower.By Rational Parameters Design, can reach very high demist efficient.

Description of drawings

Fig. 1, Fig. 3, Fig. 4, Fig. 6, Fig. 7 are five example structure schematic diagrames of downward air discharge cyclone demister.

Fig. 2 is the vertical view of Fig. 1, and Fig. 5 is the vertical view of Fig. 4.

Among the figure: 1, gas inlet pipe; 2, spiral case; 3, liquid collecting cylindrical shell; 4, base plate; 5, blast pipe; 6, guide shell; 7, discharging tube; 8, spinning disk.

The specific embodiment

As Fig. 1 and Fig. 2, the spiral case of gas access, spiral case 2 tangentially are provided with the gas inlet pipe 1 of rectangle, and liquid collecting cylindrical shell 3 links to each other with spiral case 2.Blast pipe 5 stretches into certain altitude in the liquid collecting cylindrical shell 3, and the liquid collecting cylindrical shell is stretched out in the lower end, and outlet downwards.Liquid collecting cylindrical shell 3 is provided with toe board panel 7, and the low side of base plate 7 is provided with discharging tube 7.

As Fig. 3, the spiral case of gas access, spiral case 2 tangentially are provided with the gas inlet pipe 1 of rectangle, and liquid collecting cylindrical shell 3 links to each other with spiral case 2.Blast pipe 5 stretches into certain altitude in the liquid collecting cylindrical shell 3, and the liquid collecting cylindrical shell is stretched out in the lower end, and outlet downwards.Liquid collecting cylindrical shell 3 tops are provided with the cylindric guide shell 6 coaxial with following blast pipe 5, and liquid collecting cylindrical shell 3 is provided with toe board panel 7, and the low side of base plate 7 is provided with discharging tube 7.

Fig. 4 and Fig. 5 represent to be provided with between guide shell 6 and the blast pipe 4 the oblique spaced spinning disk 8 of circumference, and spinning disk 8 utilizes the principle of inertial separation, further improve gas-liquid and remove fog effect.

Fig. 6 represents that base plate 4 tilts to both sides.Fig. 7 is that base plate 4 is to polygon inclination.

This demister operation principle is: 1 contains liquid fog body through what spiral case 2 constantly flowed into from the gas access, rotation at a high speed in the liquid collecting cylindrical shell 3 of blast pipe more than 5, the liquid mist is by centrifugation, wherein liquid moves radially to the inwall of cylindrical shell 3 laterally and forms liquid film, and liquid film flows downward and compiles the back at base plate and discharge from the lower discharging tube; Gas then continues to be rotated down in the inboard, enters blast pipe 5, discharges downwards; Part enters the gas of cylindrical shell 3 after arriving base plate 4, turns back to the inside upwards, finally also enters down blast pipe.

Base plate 4 has 5~65 ° gradient, liquid residue when the dirty thing that can alleviate base plate deposits, avoids demister to stop transport.
