Abstract
The utility model discloses a bubble cap absorption demonstration apparatus. The apparatus comprises box body possessing a liquid inlet and a liquid outlet. A bottom of the box body is vertically sealed and provided with a gas raise pipe from bottom to top. An upper end clearance of the gas raise pipe is provided with a bubble cap which is hanged in the box body. A sidewall of the bubble cap is provided with tooth seams which are arranged circumferentially with intervals. An upper end of the gas raise pipe is higher than an upper edge of the tooth seams. The box body is provided with a visual portion used for observing the bubble cap. The box body is added. The box body is used for holding a liquid. After the liquid is injected in the box body, a liquid level of the liquid is between an upper port of the gas raise pipe and the tooth seams of the bubble cap and a gas is injected into the gas raise pipe so that bubble cap absorption demonstration can be performed. The visual portion of the box body is convenient for directly observing a bubble cap absorption process.
Description
Technical field
The utility model relates to a kind of bubble-cap and absorbs apparatus for demonstrating.
Background technology
At present, in teaching at " Principles of Chemical Engineering " course about absorption, need to demonstrate self principle of absorption with bubble-cap, and traditional bubble-cap is industrial bubble-cap, because volume is large and be not suitable for teaching needs, this just student is understood to the principle of bubble-cap absorption and the operating process of observation bubble-cap absorption has brought certain difficulty.Chinese patent CN201930562U discloses a kind of bubble cap for teaching, comprise bell bubble cap, the lower ending opening place axial location of bubble cap is fitted with riser, the upper end insertion end of riser is that outlet side, lower end external part are inlet end, between the outer wall of riser and the inwall of bubble cap, there is an annular gap, and offer circumferentially uniform slot in the part of the corresponding annular gap of bubble cap.The bubble-cap volume of this structure is little, but due in actual presentation process, need liquid that slot is flooded and just can be carried out afterwards, and bubble-cap does not have relevant matching component, has brought trouble to student's demonstration operation.
Utility model content
The purpose of this utility model is to provide a kind of bubble-cap absorption apparatus for demonstrating that can be used for carrying out the teaching of bubble-cap principle of absorption.
The utility model adopts following technical scheme:
A kind of bubble-cap absorbs apparatus for demonstrating, comprise the casing with inlet and leakage fluid dram, bottom half vertically seals and is coated with riser from lower to upper, the gap, upper end of riser is arranged with the outstanding bubble-cap being loaded in casing, the sidewall of bubble-cap is provided with circumferential spaced apart slot, the upper end of riser is higher than the upper edge of slot, and on casing, is also provided with the visible section for observing bubble-cap.
Described casing is the transparent body, and described visible section is the sidewall sections that casing is corresponding with bubble-cap level.
Described riser is provided with the main gas control valve for controlling riser break-make.
The casing part of stretching out of described riser is provided with gas regulation hole, and gas regulation hole is positioned at the below of main gas control valve, and gas regulation hole place is provided with the assist gas operation valve for controlling gas regulation hole break-make.
The upper end open of described casing, the upper end open that described inlet is casing, described leakage fluid dram is arranged at bottom half, and leakage fluid dram place is provided with the liquid control valve for controlling leakage fluid dram break-make.
Adopt the bubble-cap of said structure to absorb apparatus for demonstrating, owing to having increased casing, casing is for carrying liquid, after filling liquid in casing, make the liquid level of liquid between the upper port of riser and the slot of bubble-cap, and just can carry out bubble-cap to injecting gas in riser and absorb demonstration, and the visible section of casing is convenient to directly observe bubble-cap absorption process.
Further, casing adopts the transparent body, makes the making of casing simpler.
Further, the casing part of stretching out of riser is provided with adjusting tracheae, by regulating tracheae can adjust the gas flow of being discharged by riser upper end, for the bubble-cap absorption operation demonstration under different situations.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of embodiment of the present utility model.
Embodiment
The utility model bubble-cap absorbs the embodiment of apparatus for demonstrating: as shown in Figure 1, comprise casing 1, riser 6 and bubble-cap 4, wherein, bubble-cap 4 adopts structure of the prior art, for the cylindrical structure of lower ending opening, the sidewall of bubble-cap 4 is provided with circumferential spaced apart slot 5.The cylindrical structure that casing 1 is upper end open, and made by transparent plastic, casing 1 upper end open is inlet, is provided with leakage fluid dram in casing 1 bottom, leakage fluid dram place is connected with discharging tube 2, and discharging tube 2 is provided with the liquid control valve (not shown) for controlling discharging tube break-make.Riser 6 is made up of transparent plastic equally, casing 1 bottom is passed in its upper end from lower to upper axial seal, the upper end insertion end of riser 6 is that outlet side, lower end external part are inlet end, be provided with main gas control valve 3 stretching out in casing part of riser 6, main gas control valve 3 is for controlling the break-make of riser 6; In casing part, be provided with successively from top to bottom two gas regulation holes stretching out of riser 6, gas regulation hole place is connected with respectively and regulates tracheae 7, on two adjusting tracheaes 7, be respectively equipped with assist gas operation valve (not shown), assist gas operation valve is for controlling the corresponding break-make that regulates tracheae separately, regulate tracheae 7 to be positioned at the below of main gas control valve 3, by the adjusting that cooperatively interacts of main gas control valve 3 and assist gas operation valve, can adjust the gas flow of being discharged by riser 6 outlet sides.The outstanding upper end that is contained in casing interior 1 and is sheathed on riser 6 of bubble-cap 4, the upper end of riser 6 higher than the upper edge of each slot 5, has annular gap between the outer wall of its riser 6 and the inwall of bubble-cap 4 lower than the upper end of bubble-cap 4.
When above-described embodiment specifically uses, close the liquid control valve on discharging tube 2, to the interior filling liquid of casing 1, make the liquid level of liquid between the upper port of riser 6 and the slot of bubble-cap 4, the lower end of riser 6 connects fan blower, by fan blower to the interior injecting gas of riser 6, and regulate main gas control valve 3 and two the assist gas operation valves that regulate on tracheae 7 on riser 6 by cooperation, adjust the gas flow of being discharged by the outlet side, upper end of riser 6, for the bubble-cap absorption operation demonstration under different situations.
In other embodiments, casing also can adopt square structure, and the upper end of casing also can adopt enclosed construction certainly, and an opening is set on casing as inlet.
In above-described embodiment, because casing is the transparent body, the sidewall that sees through casing can observe directly bubble-cap, therefore, the sidewall sections corresponding with bubble-cap level of casing is visible section, and in other embodiments, casing also can not adopt the transparent body, windowpane is set on wall box and also can observes bubble-cap, windowpane is visible section like this.
