Description
Technical field
The utility model relates to a kind of environmental protection equipment, in particular to a kind of DTRO film rod structure suitable for high-temperature medium.
Background technique
The temperature that traditional DTRO diaphragm is born is generally below 45 DEG C, is not able to satisfy some needs and maintains to 60-80 DEG C
In the purification of material medium, concentration, application range is narrow, such as: in animal protein separation concentration process, it is necessary to protect
It demonstrate,proves temperature of charge and is not less than 60 DEG C, otherwise material can be caused to deform.And conventional DTRO running temperature only up to 45 DEG C, because
This technical staff develops a kind of novel high temperature resistant DTRO by the developmental research to materials such as membrane material, flow guiding disc, shells
Component, maximum operating temperature have greatly widened DTRO application field up to 80 DEG C, are biochemistry, pharmacy, food, fine chemistry industry
Equal fields provide new concentration and separation means.
It is seldom in the application of engineering field although the principle of this technology is known dawn already, it is basic at present
The laboratory test stage is rested on, is applied on a small quantity in industrial system, the trial period is generally also only, is not yet widely answered
With and promote.Currently, Major Difficulties of the DTRO in fields such as some food, pharmacy are not adapt to the temperature of medium.
Utility model content
The utility model in order to make up for the deficiencies of the prior art, provides that a kind of structure novel, medium flow field flux be big, safety
Reliably, the high DTRO film rod structure suitable for high-temperature medium of effect.
The utility model is achieved by the following technical solution:
A kind of DTRO film rod structure suitable for high-temperature medium, including center pull rod, it is characterised in that: the center pull rod
On be equipped with high temperature resistant flow guiding disc and high temperature resistant diaphragm and intersect the membrane module stacked, and outermost is high temperature resistant to membrane module up and down
Flow guiding disc, membrane module both ends pass through lip-shaped ring respectively and are connected with upper end cover and lower cover, wear respectively on the outside of upper end cover and lower cover
Equipped with upper end pull rod bushing and bottom end pulling bar bushing, permeate is offered on bottom end pulling bar bushing and is exported, symmetrical two on lower cover
Side is separately installed with water inlet and concentrated solution outlet.
The film rod structure of the utility model, membrane module have two layers of high temperature resistant flow guiding disc to seal pressure high temperature resistant diaphragm up and down,
Pressure, the temperature of operation are significantly larger than similar product in the market.
The more excellent technical solution of the utility model are as follows:
The fixed spiral shell of upper end fixture nut and lower end is equipped on the outside of the upper end pull rod bushing and bottom end pulling bar bushing respectively
Mother is fixed membrane module from both ends, realizes whole connectivity.
The O-shaped close of blocks central aperture is equipped in the center pull rod between the lowermost high temperature resistant flow guiding disc and lower cover
Seal is sealed intermediate hole, realizes the concentration and separation effect of membrane module.
The material of the high temperature resistant diaphragm is the organic material that heat resisting temperature is higher than 60 DEG C；The material of high temperature resistant flow guiding disc is
UPVC material of the heat resisting temperature higher than 60 DEG C breaches market upper diaphragm convenient for film column to be applied in 60 DEG C of liquid medium
Limitation of the running temperature no more than 45 DEG C.
The utility model structure novel, medium flow field flux is big, and securely and reliably, effect is high, and running temperature reaches as high as 80
DEG C, DTRO application field is greatly widened, suitable for sewage zero-discharge, high-salt sewage concentration, food and drink pharmaceuticals industry
Product concentration, purification etc..
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1 water inlet, 2 concentrated solution outlets, 3 lower end fixture nuts, 4 bottom end pulling bar bushings, 5 high temperature resistant diaphragms, under 6
End cap, 7 high temperature resistant flow guiding discs, 8 upper end covers, 9 O-ring seals, 10 lip-shaped rings, 11 upper end pull rod bushings, the fixed spiral shell in 12 upper ends
Mother, the outlet of 13 permeate, 14 center pull rods.
Specific embodiment
Attached drawing is a kind of specific embodiment of the utility model.The embodiment includes center pull rod 14, the center pull rod
It is equipped with high temperature resistant flow guiding disc 7 on 14 and high temperature resistant diaphragm 5 intersects the membrane module stacked, and outermost is resistance to membrane module up and down
High temperature flow guiding disc 7, membrane module both ends pass through lip-shaped ring 10 respectively and are connected with upper end cover 8 and lower cover 6, upper end cover 8 and lower cover 6
Outside is equipped with upper end pull rod bushing 11 and bottom end pulling bar bushing 4 respectively, and permeate outlet is offered on bottom end pulling bar bushing 4
13, symmetrical two sides are separately installed with water inlet 1 and concentrated solution outlet 2 on lower cover 6；The upper end pull rod bushing 11 and lower end are drawn
