Description
Technical field
The present invention relates to the foam removal knockout drums for gas-liquid separation.
Background technique
In the industry such as chemical industry, petroleum, sulfuric acid, medicine, light industry, it is usually directed to the foam removal that can be realized gas-liquid separation
Knockout drum, foam removal knockout drum are mainly used to separate gas and liquid.In use discovery, due to mist rise effect of inertia and
Gas velocity, in isolated gas can entrainment and drop, usual people all solve the problems, such as this with wire mesh demister or spiral board,
But wire mesh demister resistance is big, not easy cleaning, spiral board complex manufacturing technology, higher cost.
Chinese patent CN204865264U discloses a kind of " Despumation device of gas-liquid separator ", which includes upper
The cone cap in face and following cone bottom, wherein cone bottom is the annular cone bottom that top is circular hole, cone cap and annular cone bottom are arranged in same
On center line, cone cap and annular cone bottom are linked together with multiple arcs plate, to form a circle gradient downward in device side
Bending outlet.The Despumation device is mounted on the gas outlet of gas-liquid separator when use, gas is in the mistake for rising discharge
Cheng Zhong is stopped by the cone cap of upside, then along cone cap and bores the outside effluent in channel formed between bottom, gas drives in gas velocity
Lower rising discharge, realizes gas-liquid separation, foam removal.Existing this Despumation device has the following problems: the object after boring cap foam removal
For material it is possible to containing foam, it is clean that foam is not easy removal；This outer cone cap is connected on cone bottom by arc panel, passes through arc panel
Connection cone cap and cone bottom, the setting of arc panel, occupy the portion of channel between cone bottom, cone cap, foam flow are influenced, thus shadow
Production efficiency is rung, frothy arc panel is accounted for and needs often cleaning, this also will increase the use cost of product.
Summary of the invention
The purpose of the present invention is to provide a kind of foam removal knockout drums that can be improved foam removal effect.
In order to solve the above technical problems, technical scheme is as follows:
A kind of foam removal knockout drum, is provided with material inlet including lower end, upper end is provided with the tank body of gas vent, in the tank body
Despumation device is provided between the material inlet and gas vent, Despumation device includes cone cap and lower cone setting up and down
The small head end of ring, cone cap and lower conical ring is upward and axis vertically extends, and small head end position directed downwardly is additionally provided in tank body
The small head end of upper conical ring on the upside of lower conical ring, upper conical ring extend into the inner hole upper end of lower conical ring, bores the inner wall extending direction of cap
Intersect with the inner wall of upper conical ring, bores and form foam removal channel between cap and upper conical ring.
The periphery of lower conical ring is fixed on the inner wall of the tank body, and cone cap is fixed on tank body by the lifting of vertical connection strap
Top.
The vertical connection strap has at least two, and each vertical connection strap is two neighboring perpendicular along the circumferentially-spaced arrangement for boring cap
To forming gas passage between connection strap.
Cone cap, lower conical ring are coaxially set with the tank body, and the gas vent is in the positive upside of the cone cap.
The extending direction of material inlet and the tangential direction of tank body are consistent.
The periphery of upper conical ring is fixed on the inner wall of tank body, and welding is connected at the top of the lower end outside of upper conical ring and lower conical ring.
The invention has the benefit that in use, material enters tank body through material inlet, containing frothy material by cone
Then the guide functions for boring cap are received in cap foam removal, the foam containing steam flows to upper conical ring, upper conical ring realization pair along the guiding of cone cap
The foam removal again of material guarantees that liquid gas is sufficiently separated, gas flows to gas vent through gas passage by foam removal layer by layer.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one embodiment of the present of invention.
Specific embodiment
A kind of embodiment of foam removal knockout drum includes that lower end is provided with material inlet 6, upper end is provided with gas as shown in Figure 1:
The tank body of body outlet 1, the bottom of tank body is provided with liquid outlet 5, in the present embodiment there are two material inlets, each material inlet
Extending direction is consistent with the tangential direction of tank body.Despumation device is provided between material inlet and gas vent in tank body,
Despumation device includes the cone cap 9 set gradually along the vertical direction, upper conical ring 8 and lower conical ring 7, cone cap, upper conical ring, lower conical ring with
Tank body is coaxially set, and bores the small head end of cap and lower conical ring upward, the small head end of upper conical ring downward, upper conical ring, lower conical ring it is outer
The welding of Zhou Junyu inner tank wall is connected, and the small head end of upper conical ring extend into the inner hole upper end of lower conical ring, the small head end of upper conical ring to
Under protrude from the upper end of lower conical ring, the gear that extends downward is tilted so as to form one along structure, the lower end outside of upper conical ring with
Welding is connected at the top of lower conical ring.Cone cap is lifted on the top of tank body by vertical connection strap 2, is formed between adjacent vertical connection strap
Gas passage is bored and is arranged independently of one another between cap and upper conical ring, and the inner wall extending direction for boring cap intersects with the inner wall of upper conical ring, cone
Foam removal channel 3 is formed between cap and upper conical ring.The stub end maximum gauge for boring cap is greater than the small head end minimum diameter of lower conical ring.
The material for containing foam and gas when use enters in tank body through material inlet, and material is cut along the tube wall of tank body
To flowing, in foam uphill process, the foam rising on tank body periphery encounters lower conical ring, under the liquid attached jet in foam, realizes
Foam removal, lower end protrude from the upper conical ring of lower conical ring, can flow to upside, the foam in the middle part of tank body because of pressure to avoid liquid
Rising encounters cone cap, and after cone cap foam removal, the foam containing gas is struck again on upper conical ring, carries out foam removal again,
Last gas is discharged through gas passage, the gas vent between adjacent vertical connection strap, and liquid is then discharged through liquid outlet.This production
While product guarantee foam removal effect, bores between cap and upper conical ring without any blocking, foam removal efficiency, time cleaning frequency can be improved
Long, when cleaning, vertical connection strap position does not have to cleaning without foam substantially, and other positions are also easier to clearly compared with prior art
It washes.
