Definitions
- the invention relates to a pump for the delivery of hot corrosive liquids, in particular molten salts, consisting of a pump tube, a delivery pipe immersed in the liquid and at least two valves in which the liquid is cyclically demanded by pressurization
- salt melt In various chemical production processes, for example in the Deacon process with inorganic salt melts for the direct oxidation of HCl to chlorine, salt melt must be required in a pumping circuit in order, for example, in one
- the object was to construct a pump device for aggressive liquids, in particular salt melts, which does not have the disadvantages of the pumps mentioned above.
- the pump should be used like a simple plug-in pipe in a storage container or reactor. It should contain as few components as possible and largely do without mechanical or electrically moving parts and make pressurization of the reactor superfluous
- a device for demanding, in particular, hot, corrosive liquids, in particular salt melts consisting of a pump tube with a gas supply and a gas discharge, a feed tube which is openly immersed in the liquid and optionally arranged coaxially to the pump tube for the liquid and at least two valves, openings between the pump tube and delivery pipe being provided between the valves, the valves being opened by the respective liquid flow and closing in the direction of gravity
- the use of different valves with different specific weights of the two valve closing bodies is advantageous for problem-free operation of the requirement.
- the shooting body of the lower valve (inlet valve) should float as lightly as possible in order to
- the body of the upper valve should only open when it is actually being conveyed, but otherwise close securely to prevent the fluid from flowing back, e.g. a molten salt during the reloading process. It must therefore have the highest possible specific weight.
- a potassium / copper chloride melt with a density of about 3 g / cm
- the pump device according to the invention is distinguished from other conveying devices by its simplicity. It comes with only two moving ones
- valve seat and tube are always almost at the same temperature, so that secondary voltages, which could possibly lead to failure or breakage of the component, are particularly avoided can if the valve seat and tube are made of the same material, e.g. Quartz.
- the particular advantage of the device according to the invention lies in the fact that the reactor vessel function (for example in the case of a clocked pressurization for pneumatic requirement) can be completely separated from the pump function, so that the reactor vessel only allows the gas-tight inclusion of the liquid, for example the melt, as far as possible in depressurized condition, must guarantee
- Another particular advantage of the device according to the invention is that it can ensure a continuous flow of molten salt through the reaction column in spite of an individual, clocked procedure if it is operated in succession in conjunction with at least one similar pumping device in such a way that at least one pump with a corresponding temporal overlap is in funding mode.
- the device according to the invention can be controlled completely decoupled from the molten salt via the gas phase, the intervals being able to be controlled either time-clocked or pressure-clocked
- the device according to the invention can also be guided through the bedding of a full-body column. If it is pushed through the bedding zone by a guide tube sealed at the top against a feed gas bypass, it can be pulled out if necessary without disturbing the bedding
- a closable opening can be provided above the outlet valve in order to be able to drain the melt in the delivery pipe, for example for cleaning purposes
- the delivery volume per cycle of the device according to the invention can be influenced by changing the immersion depth in the sump and constructively by changing the diameter of the pump tube in relation to the delivery pipe
- the demand cycle can be shortened in particular by improving the inflow condition during the reloading phase.
- a group of several valves arranged in a circle can be provided in the bottom area of the pump pipe and the delivery pipe closed at this height held
- Fig. 1 shows a schematic section through a pump according to the invention during filling
- Fig. 2 shows the pump according to Fig. 1 during the request 3 shows the pump according to FIG. 1 during refilling
- FIG. 4 shows a variant of the pump according to the invention with an external delivery pipe during the delivery
- both ball valves 3, 4 with the balls 12 or 13 and the valve seats 14 or 15 are opened by the melt 5 flowing into the delivery pipe 2 from below, the gas-side vent 9 with valve 10 is open.
- the pump gas for example the feed gas of a reaction with closed vent 9 with valve 10
- the pump tube 1 presses the melt 5 through the
- Melt pressure is printed and a refill of the pump tube 1 enables
- pump tube 1 and delivery pipe 2 can also be reversed (see FIG. 4).
- This arrangement allows the gas volume required for the delivery to be particularly small and thus the cycle time to be made particularly short.
- Advantageous in this arrangement is a near the inlet
- the basic function of the pump device according to the invention has been tested in a test arrangement with zinc chloride hydrate (density: 2.0 g / cm 3 ) as the test liquid.
- the test ran at room temperature.
- the test model had the following components and dimensions:
- Inlet valves 6 pieces in a circular arrangement
- Ball diameter of the striker 5 mm
- test model showed the following performance data in operation
