Technical field

The present invention relates to a kind of vertical tube falling vaporising device, more particularly in a kind of vertical tube falling evaporator from respin Flow vapour liquid separator.

Background technique

In the prior art, in most of vertical tube falling vaporising devices separator design using separator volume space into Row separation, since steam flow rate is larger, usually carrying of liquids enters next stage process, not so as to cause the effluent quality after separation It is up to standard, for the technique requirement for meeting effluent quality, often increase the equipment size and transport disengaging height of separator thus.

Traditional vapour liquid separator problem is mainly manifested in, and A vapor-liquid separation effect is poor, and many effluent qualities are not up to standard；B Equipment size is big, and land occupation is big, and heat dissipation area is big, low efficiency.

Summary of the invention

In view of this, the main purpose of the present invention is to provide the self weight eddy flow vapour-liquids in a kind of vertical tube falling evaporator point Power of the falling film concentration liquid by self weight from high position decline is made full use of by the technical program from device, concentrate leans on itself Gravity vertical landing, steam from horizontal direction eddy flow and go out, self-contained drop throws away to the eddy flow state that is converted to, accelerates vapour Liquid separates, and guarantees not carry concentrate in steam, to ensure that the pure property of steam, steam is condensed into the water quality of water greatly It is purified, thus the effective solution efficient operation of separator, not only separation substantially reduces separator volume space.

In order to achieve the above object, the technical scheme of the present invention is realized as follows: in a kind of vertical tube falling vaporising device Self weight eddy flow vapour liquid separator, including shell separator is provided with mixture input port at the top of the shell separator, separates Steam (vapor) outlet is provided on the side wall of device upper part of the housing, it further includes having vapour-liquid to lead that shell separator bottom, which is provided with concentrated solution outlet, Cylinder and concentrate sieve, vapour-liquid guide tube upper end are fixed in shell separator and are connected with mixture input port, vapour-liquid Guide tube lower end is provided with concentrate sieve.

As further technical solution, several steamings are provided between the vapour-liquid guide tube outside side wall and shell separator Vapour eddy flow guide card.

As further technical solution, the steam eddy flow guide card is inclined outwardly on the outside of the angle and vapour-liquid guide tube of stretching Tangential direction be 45 °.

It further include variable diameter conduit, variable diameter conduit upper end and shell separator inner wall as further technical solution Mutually fixed, variable diameter conduit lower end is connected with vapour-liquid guide tube lower end.

As further technical solution, the concentrate sieve generally cone cell, the cone bottom surrounding of concentrate sieve It is connected with vapour-liquid guide tube lower inner wall.

Beneficial effect after by adopting the above technical scheme is: the self weight eddy flow vapor-liquid separation in a kind of vertical tube falling evaporator Device using the self weight of falling film concentration liquid from the power of high position decline, is converted to eddy flow state by the technical program, steam with it is dense Contracting liquid difference flow direction, using existing flow velocity generate eddy flow power, steam from horizontal direction eddy flow and go out, by self-contained liquid Drop is thrown away, and accelerates vapor-liquid separation, guarantees not carry concentrate in steam, and then effectively guarantee the pure of steam, steam condensation Water supply standard is fully achieved in the water quality of Cheng Shui, has separator and efficiently separates many advantages, such as small with compact-sized space.

Specific embodiment

Specific embodiment in the present invention is described in further detail below in conjunction with attached drawing.

As depicted in figs. 1 and 2, the self weight eddy flow vapour liquid separator in vertical tube falling evaporator of the present invention, including Shell separator 1 is provided with mixture input port 2 at the top of the shell separator 1, is arranged in 1 upper portion side wall of shell separator There is steam (vapor) outlet 3, it further includes having vapour-liquid guide tube 5 and concentrate sieve 6 that 1 bottom of shell separator, which is provided with concentrated solution outlet 4, 5 upper end of vapour-liquid guide tube is fixed in shell separator 1 and is connected with mixture input port 2, the setting of 5 lower end of vapour-liquid guide tube There is concentrate sieve 6.

As further embodiment, several steamings are provided between 5 outside side wall of vapour-liquid guide tube and shell separator 1 Vapour eddy flow guide card 7.

As further embodiment, the steam eddy flow guide card 7 is inclined outwardly 5 outside of angle and vapour-liquid guide tube of stretching Tangential direction be 45 °, the outwardly directed width of steam eddy flow guide card 7 be 2-5mm.

It further include variable diameter conduit 8 as further embodiment, 8 upper end of variable diameter conduit and 1 inner wall of shell separator Mutually fixed, 8 lower end of variable diameter conduit is connected with 5 lower end of vapour-liquid guide tube.

As further embodiment, the concentrate sieve 6 generally cone cell, the cone bottom surrounding of concentrate sieve 6 It is connected with 5 lower inner wall of vapour-liquid guide tube.

At work, the mixture that steam and concentrate are constituted smoothly is flowed into vapour-liquid by variable diameter conduit 8 to the present invention In guide tube 5, sink under the effect of gravity, most of concentrate is sifted out by concentrate sieve 6 in mixture, and steam is led to by side Cross the outflow of steam swirl vane 7, generate eddy flow spiral on the outside of vapour Huaihe River guide tube 5, the fine drop of entrainment by eddy flow from Mental and physical efforts and gravity sink down into concentrated 4 discharge of liquid outlet in concentrate buffer area of 1 bottom of separator shell, clean steam It is discharged through steam (vapor) outlet 3.

The above, preferable possible embodiments only of the invention, the range being not intended to limit the invention.
