Abstract
The utility model provides an adjustable foam remover with silk screens, which relates to a foam removing device with silk screens used for separating gas and liquid. The utility model is characterized in that a gas guiding cylinder with silk screens is arranged in the middle part of the foam remover. An air door with a silk screen is arranged in the gas guiding cylinder, and the air door with a silk screen can be moved up and down, and/or can be opened and closed. The foam remover can be provided with a layer with single-layer horizontal foam removing silk screen or a layer with double-layer horizontal foam removing silk screen. The action of the air door is controlled by a driving device; the position of the air door, and the opening and the close of the air door can be regulated according to the magnitude of air quantity, making silk screens keep a high foam removing efficiency; the position of the air door, and the opening and the close of the air door can also be regulated according to liquid catching quantity on the silk screen, making that foam removing area satisfies the maintenance and the dynamic balance of liquid catching quantity and liquid drain quantity in the foam removing silk screen, the occurrence of liquid flooding is avoided, and the high efficiency of foam removing is guaranteed.
Description
The utility model relates to a kind of wire mesh demister that gas-liquid separates that is used for.
Adopted wire mesh demister at present on some chemical industry equipments, the foam removal efficient of this demister depends on the operating gas velocity by silk screen, foam removal efficient instability when the tolerance significant change.For addressing this problem, the inventor has designed a kind of permanent wire mesh demister (ZL93215526.X) of imitating, and principal character is that control power set, air door and gas cylinder are arranged.Operation principle is: when tolerance was design load, door opening, demister had maximum foam removal area.When stingy amount took place, air door was closed, and the foam removal area reduces, and the operating gas velocity of process silk screen has improved, and foam removal efficient can not reduce because of the variation of tolerance.This permanent wire mesh demister of imitating has been broken through the changeless pattern of traditional wire mesh demister foam removal area, and foam removal area and operation tolerance are adapted.Find that through practice the patented product is preventing on the liquid flooding problem limitation is arranged.When changing or do not change, tolerance catches the excessive situation of liquid measure, the former permanent danger that wire mesh demister can not reduce liquid flooding by the foam removal area that enlarges silk screen of imitating.Simultaneously the adaptive capacity that changes for multistage tolerance also a little less than.Imitate demister so wish to design a kind of perseverance that can avoid liquid flooding to send.
The purpose of this utility model is to improve permanent structure of imitating the wire mesh demister patented product, and this structure can realize that the foam removal area is adjustable, makes it to reach to catch the degree that liquid measure and lifting rate are kept dynamic equilibrium, avoids the generation of liquid flooding, and keeps the permanent foam removal effect of imitating.
The purpose of this utility model adopt following design this to: the main distinction of they and former patent is that on gas cylinder and the air door, gas cylinder of the present utility model and air door are made of the silk screen layer of adjustable foam removal.Be provided with the silk screen gas cylinder at demister middle part, be provided with in the tube can be therein up and down and/or the silk screen air door that opens and closes, and be provided with transmission mechanism by valve stem control air door.Air door can move up and down, and changes the foam removal area in the gas cylinder scope.The double-deck screen net structure of former patent is modified into three types structure, and their common feature structure is that gas cylinder and air door are made of silk screen, and its distinguishing characteristics is: adjustable I type is following one deck silk screen; The structure of following one deck silk screen of adjustable eurymeric is a stairstepping; Adjustable ware type has two-layer silk screen up and down.
Effect of the present utility model is fairly obvious: the one, and foam removal efficient is constant reliable, and the 2nd, can regulate the foam removal area according to actual conditions and make it to reach the dynamic equilibrium of catching liquid measure and lifting rate, avoid the generation of liquid flooding.Be a kind of effect stability, safe and reliable Despumation device.
The adjustable I type wire mesh demister structural representation of Fig. 1: embodiment 1;
The adjustable eurymeric wire mesh demister structural representation of Fig. 2: embodiment 2;
The adjustable II type wire mesh demister structural representation of Fig. 3 (a): embodiment 3;
The adjustable II type wire mesh demister structural representation of Fig. 3 (b): embodiment 3.
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Embodiment 1:
Adjustable I type wire mesh demister of the present utility model as shown in Figure 1.Establish a wind gas cylinder 2 falling foam device 1 middle part, be provided with the silk screen air door 3 that can move up and down therein and/or open and close in the tube 2, and be provided with transmission mechanism 5 by valve stem 6 control air doors 3.Establish the horizontal foam removal silk screen layer 4 of individual layer in the demister bottom.
The utility model operational circumstances: when minimum tolerance took place, air door 3 was displaced downwardly to extreme lower position, foam removal this moment area minimum.When tolerance becomes big continuously, move on the air door 3, increase the foam removal area gradually.When increase was fallen on the tolerance rank, air door 3 conductings enlarged the foam removal area rapidly.If catch the situation that liquid measure is excessive or have extra air quantity to increase under design maximum air quantity condition, air door 3 moves on rapidly increases the foam removal area, and the gentle speed of foam removal area is constant to remain valid.The essence of this operation is to make it to reach and catch liquid measure and lifting rate is kept dynamic equilibrium and kept high foam removal efficient by regulating the foam removal area, avoids the generation of liquid flooding.
Embodiment 2:
As shown in Figure 2, adjustable II type of the present utility model is a compact type.Its structure is identical with embodiment 1 basically, and the difference of its structure is characterised in that silk screen layer 4 is designed to stairstepping, and its adjustable range is big, and under the foam removal area condition identical with embodiment 1, the diameter of demister 1 can dwindle.
Embodiment 3:
Shown in Fig. 3 (a) and (b), the utility model adopts two foam-removing layer structures, on present embodiment 1 architecture basics, establish silk screen layer 7 at demister 1 top, its air door can adopt individual layer [Fig. 3 (a)] or double-deck [Fig. 3 (b)] structure, the foam removal effect of such structure is more reliable, but investment is big.
