Definitions
- the invention relates to a metering system for introducing a solid into a liquid which is able to dissolve this solid.
- the invention relates to a metering system for the additization of heavy marine diesel oil with ferrocene and / or ferrocene derivatives.
- a metering device for dissolving a solid in a side stream of a liquid is known.
- this invention is directed to a metering device which is suitable for the water treatment of water flowing in the swimming pool with fixed amounts of a chlorine-containing substance which is initially in solid form (granules).
- An essential component of this device is a container with a relatively large amount of solid, which is covered with liquid. It is assumed that the concentration of the dissolved solid in this liquid is constant. This is then drawn off accordingly and metered into the main stream while fresh liquid is topped up in the container.
- the object of the invention is therefore to provide a metering system which does not have the disadvantages described and which can be used for the application areas mentioned.
- the system should be relatively simple and robust to work under to be able to work without problems and maintenance under the conditions mentioned.
- a container (1) for holding liquid, an inlet (3) which can be regulated via a valve (2), a container (4) for the solid which is located inside the container (1) and at least partially penetrated by the liquid therein can be a metering pump (7) downstream of an outlet (6) and possibly further units or control devices for temperature and filling
- constant additives can also be used under extreme conditions e.g. achieve on board a large ship suitable for sea use in heavy seas.
- a preferred embodiment additionally includes a device (8) which constantly mixes the liquid in the container (1) and flows through the container (4) which contains the additive in solid form.
- a device (8) which constantly mixes the liquid in the container (1) and flows through the container (4) which contains the additive in solid form.
- the liquid in the container (1) is constantly circulated by a pump.
- a stirrer is preferably used.
- the design of the stirrer eg propeller stirrer
- its dimensioning, speed and its drive are freely selectable and depend on the shape and size of the container (1), the viscosity of the liquid, etc.
- the person skilled in the art knows which stirrer he is using under which framework conditions can best be used.
- the metering system has an addition device (9) for filling the container (4) with solid.
- this addition device which in the simplest case is a funnel, the solid is added.
- metered addition can take place in the form of ready-made units, by measuring beaker or by manual weighing.
- An automatic feed of the solid can also be installed.
- all devices that are intended for measuring and dosing solids and that can be found in corresponding reference works, such as belt scales are suitable for this.
- the metering system can have a device for tempering the liquid in the container (1).
- These can be cooling or heating coils, for example, which are located in the container (1) and are constantly flushed with liquid.
- a double-walled container (1) is also suitable, through which cooling or heating media (e.g. steam) are passed between the two walls.
- An electric heater is also possible.
- a regulation can be provided which controls the cooling or heating in such a way that the container contents are kept constant at a certain temperature.
- the container (4) can be made of different materials and different shapes. It is important that the material should be inert to the feedstocks and that there is also the possibility that the liquid can flow through the container (4).
- the container (4) can e.g. Have pores, meshes or holes through which the liquid can flow. It is preferred to use a filter cartridge or a filter basket.
- the choice of the type of container depends on the type and shape of the solid to be detached and on the properties of the liquid. The experienced specialist will be able to make the right choice here without any problems.
- a filter basket with a metal mesh fabric with a mesh size of 0.5 to 5 mm has proven to be very suitable for the additization of heavy oil with powdered baked ferrocene.
- the solids can be supplied in various comminuted forms. All intermediate stages between coarse to finely ground solid are possible. This also includes other forms such as granules, pellets or flakes.
- the metering system contains a device (5) by means of which the liquid level within the container (1) can be regulated.
- This device is designed so that at a certain low level (Iow) of the liquid in the container (1) via the inlet (3) controlled by a valve (2) as much liquid is again introduced into the container (1) until a certain maximum level (high) of the liquid level is reached.
- Various embodiments of the device (5) can be used for this regulation, for example optical systems, liquid level indicators, flow meters, etc.
- Such measuring and control elements are known to the person skilled in the art.
- float switches are preferably used in such a way that one float switch is used for the lower (Iow) and one for the upper (high) liquid level. Regardless of the type of device (5), it is important that defined amounts of fresh liquid are always supplied.
- a preferred embodiment of the invention uses a frequency-controlled pump as the metering pump (7), which can be regulated as a function of the load or the speed of the ship's propulsion unit.
- the metering pump (7) is preferably coupled to the pump for conveying the main flow from the storage tank in order to ensure a uniform additive.
- the liquid which is fed to the container (1) via the line (3) is branched off as a secondary flow from a main flow of the liquid and then the solution is fed back to the main flow via the line (6).
- the metering unit according to the invention is suitable for metering solid additives to liquid fuels, in particular for adding heavy heating oil with ferrocene, preferably on board large ships suitable for use on the high seas.
- Heavy diesel or heating oils are classified according to ISO 8217 and have a density of approximately 0.9 to 1.0 kg / dm ⁇ .
- the dimensioning of the device essentially depends on the throughput quantities.
- the person skilled in the art will make the suitable choice here without difficulty. For example, with a main flow of several tons per hour and an intended additive concentration of up to 100 ppm, there is a container (1) with a capacity of 100 to 200 l. The container (4) should then be able to hold a few kg of solid.
- Figure 1 shows a container (1) for receiving liquid (not shown here), which is introduced via an inlet (3) which is controlled by a valve (2).
- the container (4) contains the solid (not shown here) which can be filled in via the device (9), in the simplest case a funnel. Furthermore, a stirrer (8) can be seen.
- the inflow of fresh liquid is regulated by two float switches (5). If the liquid level reaches the lower float switch, i.e. the Iow position, the valve (2) is opened after the solids have been added. This can be done manually or automatically. When the liquid level reaches the upper float switch, i.e. the high position, the valve (2) closes.
- the solution can be passed to the consumer or combined with the main flow via the outlet (6) and a metering pump (7) controlled by means of a control device.
- FIG. 2 shows the integration of the metering system in a fuel system.
- the main flow of the fuel is fed via a line (10), if necessary via a cleaning system such as a separator (11) is introduced into a service tank (12) which is smaller in size than the storage tank (not shown here).
- a partial flow is fed to the metering system (shown here only schematically) via the inlet (3).
- the additive solution is then reintroduced into the main stream (10) via the metering pump (7) and the line (6).
- the fuel is then fed from the service tank (12) to the consumer via a pump (13).
- the fuel pump for conveying the main flow from the storage tank and the metering pump (7) can be coupled (not shown here).
- the present invention is further illustrated by Examples 1 and 2 below.
- a mixing tank model was set up in the laboratory. This model was equipped with an adjustable stirrer motor and an impeller stirrer with 1,350 revolutions. hours / min. A filter basket with a mesh size of 500 ⁇ m was used for the ferrocene entry. In addition, the model was equipped with a heating coil so that thermostatting was possible. The dependence of the solution speed on the temperature during the production of a 3% by weight ferrocene solution was checked.
