摘要： PURPOSE:To obtain the excellent gas-liquid contact apparatus with reduced warpage by the constitution wherein each shelf stage is stacked on the lowermost shelf stage placed on a support member through both side plates of a trough. CONSTITUTION:Because the liquid on a tray 3 is prevented from being directly flowed out toward a liquid falling part 5 by a barrier plate 43, a total amount of the liquid is flowed into a trough 4 and further flowed in the trough 4 to be flowed out to the liquid falling part 5 and the liquid accumulated in the liquid falling part 5 is flowed onto the tray 3 of a lower side through a gap 6. On the other hand, a gas is passed through pores of the tray 3 and passed through the liquid distributed on the tray 3 to form foam to carry out gas-liquid contact effectively. Because each trough 4 has mutually connected both side plates forming said trough and has a structure wherein the liquid in the trough 4 can be mutually flowed, when a flow amount of the liquid flowed into each through 4 is changed, said through has a function to make uniform the flow of the liquid.

摘要： PURPOSE:To raise the strength, by alternately combining waved surfaces with flat surfaces in a header and supporting the flat surfaces of high-pressure fluid passages by the wave crest parts of low-pressure fluid passages. CONSTITUTION:Heat transfer plates 16 which have central heat transfer parts having waved surfaces 14 and have flat header surfaces 15 at both the ends, and other heat transfer plates 19 which have central waves surfaces 17 having the same phase as the waved surfaces 14 of the heat transfer plates 16 but having a larger length than the waved surfaces 14 and have small flat surfaces at both the ends are alternately juxtaposed with one another. As a result, the waved surfaces and the flat surfaces are alternately combined with one another in the header 20. Since high pressure fluid is caused to flow through header passages wherein the flat surfaces are out of contact with the crests of the waved surfaces and low pressure fluid is caused to flow through header passages wherein the flat surfaces are in contact with the troughs of the waved surfaces, the pressure-resisting property of the header is improved.

摘要： PURPOSE: To make a liquid which flows out of a filler in the lowermost part flow downward smoothly along a support grid by installing a support grid composed of honeycomb cores next to the lowermost end of the filler. CONSTITUTION: In a packed tower main body 100, fillers 12 are layered in tower's axial direction to compose respective blocks. A support grid composed of honeycomb cores 50, 51 is fixed in the packed tower 100 at the lowermost end 4 of the fillers l-2 by a supporting plate 52. Consequently, a liquid flowing downward from the upper side off the packed tower 100 flows down successively through the filler 2 and the filler 1 and a rising gas 11 rises upward from the space 12 and gas-liquid contact is carried out in the surface of the fillers 2, 1 to separate components of the liquid flowing downward and the rising gas, and then the liquid flowing downward flows out of the lower end of the fillers and flows down along a cell. In this way, since the support grid is composed of these honeycomb cores 50-51 with high open degree, the liquid can flows down with little pressure loss.

摘要： PURPOSE: To provide a filler material of good rectification efficiency for activating the renewal of the free surface of a liquid film, improving the turbulence or dispersion effect in the filler material and also improving the gas-liquid contact efficiency. CONSTITUTION: A number of projected sections 2 and projected sections 3 are formed on the surface of a sheet material 1, and the height of the projected sections 2 and that of the projected sections 3 are different, and the sections are formed alternately in the flowing-down direction of a liquid 4. As the heights of projected sections 2 and 3 are varied to the flowing-down direction, the liquid film thickness of the liquid 4 is varied to activate the renewal of the free surface of the liquid film. It accelerates the turbulence or dispersion effect of the liquid 4 to increase the gas-liquid contact interfaces and also increase the speed between gas and liquid.

摘要： PURPOSE:To easily produce packing enhancing the efficiency of vapor-liq. contact and to improve the performance of an air separator by fitting the packing in a rectifying column in which vapor-liq. contact is carried out. CONSTITUTION:Many elliptical protrusions are disposed on the surface of a thin layer 1 and protrusions 2 in a 1st tow and protrusions 3 in a 2nd row are zigzag arranged. A liq. 4 flowing down to the thin layer 1 collides against a 1st protrusion 3, the flow is divided into two flows and these two flows collide against next two protrusion 2. Such division into two flows are successively repeated and a very satisfactory liq. distribution is obtd. on the surface of the thin layer 1.

摘要： PURPOSE:To provide a gas-liquid contact device where the pressure loss of perforated plates assembled in a fractionator is decreased and the operating range of the fractionator is made wide. CONSTITUTION:The region of small holes 8 opened obliqutely in the radius direction of a perforated plate 5 is provided. Consequently since by the action of the region of small holes opened obliqutely in an inside direction, the liquid in the outer peripheral part flows in the inside direction, the thickness of the liquid on the perforated plate is made uniform to obtain a gas-liquid contact device having small pressure loss and a wide operating range.
