Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1 in conjunction with Fig. 2, full-welding plate-type heat exchanger for one embodiment of the invention, this heat exchanger includes: be positioned at the plate bundle 1 of column frame, plate bundle 1 is for forming the vertical cold medium channel in media flow direction and hot media channel, plate bundle 1 is main heat exchanger components, plate bundle 1 is welded by some heat exchange plates, every two panels forms a passage, adjacency channel differs, if the 1st, it is level that 2 plates form channel direction, then the 2nd, it is vertical that 3 plates form channel direction, 3rd, it is level that 4 plates form channel direction, 4th, it is vertical that 5 plates form channel direction, by that analogy. the passage of all vertical directions and a pair side square flange and cylinder communicate, and the passage of all horizontal directions and another offside direction flange and cylinder communicate, and form the vertical cold medium channel in media flow direction and hot media channel.
Column frame includes the cuboid or the cube skeleton that are formed by 4 columns 2, and on skeleton, two ends arrange two cover plates 3 and form cavity; 4 columns and 2 cover plates form framework, primarily serve the purpose of restriction plate Shu Changdu or height column and cover plate forms framework, in this frame structure, every adjacent upright posts and this direction cover plate are provided with bolt hole and sealing surface, bolt hole is used for connecting lateral plate assembly, square flange medial surface is provided with sealing surface, coordinate with frame structure sealing surface, play sealing function, it is prevented that medium outflows.
Arrange in symmetrical both sides of column frame and be respectively arranged with thermal medium entrance side panel assembly 44 and thermal medium outlet side panel assembly 43, be separately positioned on the face of the thermal medium inlet of plate bundle 1 two columns formation corresponding with the thermal medium outlet place of plate bundle 1; Cold medium inlet side panel assembly 41 and cold media outlet side panel assembly 42, it is arranged on another symmetrical two sides of column frame, making the media flow direction that cold medium is formed vertical with the hot media channel that thermal medium is formed, such thermal medium flows to and flows to vertical with cold medium.
Referring to Fig. 3, for cold media outlet side panel assembly 42 and thermal medium outlet side panel assembly 43, all including cross section is the semicircular cylinder 4-2 cavity formed, and cylinder 4-2 and two column and two side cover plates are connected by flange 4-1, and the two ends of cylinder 4-2 are sealed by end plate 4-3; It is welded between end plate 4-3, cylinder 4-2 and flange 4-1, the cavity of cold media outlet side panel assembly communicates with the cold media outlet of plate bundle, cylinder arranges cold media outlet B and residual liquid outlet C, and wire mesh demister 5 is set at cold media outlet place and for eliminating foam; Residual liquid outlet C is that cold media outlet B is arranged upward in cold media outlet side panel assembly center near flange at the cylinder sidepiece of cold media outlet side panel assembly. The cross section that is shaped as of cavity is semicircular cylinder, cold medium in cavity after buffering gas from liquid separate, and upwards walk in cavity, liquid is to dirty, thus realizing separating. Owing to giving certain cushion space so that separating effect is obvious.
In order to realize the separation of thermal medium, thermal medium outlet side panel assembly 43 communicates with the thermal medium outlet of plate bundle, and arranges thermal medium outlet E and condensate outlet F on cylinder, arranges the wire mesh demister defoaming treatment for gas at thermal medium outlet place simultaneously. Thermal medium outlet E is arranged on the sidepiece of thermal medium outlet side panel assembly so that during placement, and thermal medium outlet upward, is provided with condensate outlet F in the other side of thermal medium outlet side panel assembly so that during placement, and thermal medium outlet is down.
In such a configuration, the cross section of cylinder 4-2 is semicircle, and the distance between diameter and two columns 2 is equal.
In one embodiment, except thermal medium outlet side panel assembly and cold media outlet side panel assembly are set to tubular structure, cold medium inlet side panel assembly 41 is also configured to the same structure, including the cavity that a cylinder is formed, for carrying out the buffering of liquid, cylinder and two columns and two side cover plates pass through Flange joint, different places is in that to arrange cold medium inlet A on cylinder, here cold medium inlet is less than cold media outlet, purpose is in order to after separating with cold dielectric gas, it is possible to discharge fully.
In one embodiment, except thermal medium outlet side panel assembly and cold media outlet side panel assembly, cold medium inlet side panel assembly are arranged to tubular structure, thermal medium entrance side panel assembly D is also configured to identical structure, including the cavity that cylinder is formed, cylinder and two columns and two side cover plates pass through Flange joint, different places is in that, arranges thermal medium entrance D on cylinder.
Work process and principle be:
Cold medium is formed the relatively low liquid mixture of temperature by material soluble in water and water, utilizes its boiling point characteristic lower than water boiling point, first evaporates with water, it is possible to purifying substances after being heated;The gas mixing that thermal medium is formed temperature higher by the material and steam that are not readily dissolved in water forms, and utilizes steam lower than 100 DEG C of characteristics that can liquefy, the material being not readily dissolved in water is purified, and the abundant recycling of heat energy.
Cryogenic liquid mixtures is entered by cold medium inlet A as cold medium, by heating through heat exchange after plate beam passage, liquid mixture temperature is made to raise, carry out full evaporation at night, low-boiling material preferential evaporation becomes gas, being discharged through wire mesh demister by cold media outlet B, all the other residual liquids are exported C by residual liquid and overflow; High temperature gas mixture is entered by thermal medium entrance D, and after plate beam passage heat exchange, temperature of gas mixture reduces, and steam coagulation becomes aqueous water to discharge from condensate outlet F, and on-condensible gas is discharged by thermal medium outlet E by wire mesh demister. Thus completing to separate.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
