Definitions
- the invention relates to an operating building for a plant, in particular for a plant for generating energy, which has a pump chamber and a cleaning chamber for cooling water.
- the invention further relates to a method for operating the operating building.
- cooling water is necessary for the operation of the plant.
- a typical example of the use of cooling water is the cooling of steam in a cooling tower of a power plant.
- the cooling water is generally taken from a natural reservoir, for example from a river or lake, first cleaned in the cleaning chamber in order to then be conveyed to system components via the pump chamber with a pump arranged there.
- the pump system delivers several cubic meters of cooling water per second.
- the flow paths, the cleaning devices for cleaning the cooling water, the pump chamber and in particular the pump are designed to be correspondingly voluminous.
- the inflow behavior of the coolant to the pump is crucial for safe and permanent, trouble-free operation of the pump. In particular, this requires a vortex-free inflow into the pump.
- the cleaning chamber and its outlet cross section are generally very narrow and tall, whereas the pump chamber downstream of the cleaning chamber is designed to be wide and flat and is designed, for example, as a covered pump chamber.
- the pump chamber downstream of the cleaning chamber is designed to be wide and flat and is designed, for example, as a covered pump chamber.
- a calming section is usually provided between the cleaning chamber and the pump chamber. This takes up a not inconsiderable amount of space, which has a negative impact on the costs for the construction of the company building.
- the company building is designed as an inlet structure on an open body of water with a number of inlet chambers so that the water flows into the individual inlet chambers evenly and as swirl-free as possible and that the bottom of the water is not whirled up or damaged by the inflowing water.
- the invention is based on the object of specifying an operating building for a system and a method for operating an operating building, in which safe system operation is ensured with low manufacturing costs of the system.
- the latter has a pump chamber for arranging a pump for cooling water and a cleaning chamber, the pump chamber directly adjoining the cleaning chamber and having a chamber geometry such that the coolant is avoided during operation of the system of disturbing vortices has a high flow rate.
- the invention is based on the surprising finding that the cleaning chamber can be arranged directly in front of the pump chamber, that is, the usual calming sections can be omitted without disturbing vortices, in particular surface vortices, occurring in the pump chamber. Avoiding the eddies can namely already be achieved by an appropriate geometric configuration of the pump chamber, which leads to a comparatively high flow rate.
- the decisive advantage of this configuration is that the elimination of the calming section leads to a reduced construction volume of the company building and thus to significantly reduced manufacturing costs for the company building.
- the chamber geometry is preferably designed in such a way that, during operation, the flow rate of the cooling liquid is increased when it enters the pump chamber.
- the flow rates for the cooling water within a cleaning machine arranged in the cleaning chamber are approximately 1 m / s. While conventional If this flow velocity is reduced to about 0.5 m / s by the settling sections when the inlet to the pump chamber is used, according to the present embodiment an increase in the velocity is provided in order to develop a sufficiently high flow velocity.
- an inlet opening via which the cooling water flows into the pump chamber, is adjoined by a wall region that runs obliquely to the chamber side wall. This avoids backflow spaces in the pump chamber, which are a typical cause of the formation of vortices.
- the pump chamber is designed for positioning the pump in such a way that the displacing action of a pump tube reliably prevents the flow from detaching from the wall despite the generally large expansion angle in the inflow region of the pump chamber.
- This is preferably achieved in that, when the pump is installed, the flow cross section for the cooling liquid flowing into the pump chamber tapers. It is possible for the diameter of the pump tube to vary within a wide range, so that both pumps with a small tube diameter and high impeller speed and pumps with a large tube diameter and low impeller speed can be used in the same chamber.
- the tube diameter and the impeller speed are selected in such a way that a low so-called “required holding pressure level * (NPSH) is achieved to avoid the so-called cavitation, that is, the formation and the abrupt collapse of vapor bubbles.
- NPSH so-called “required holding pressure level *
- the distance between the center of the pump's axis and the rear wall of the chamber and the distance from the floor of the pump suction bell are defined as a function of the suction bell diameter and the chamber size.
- the pump chamber alternatively and preferably in combination has the following features:
- a guide threshold on the chamber floor in the region of the pump which runs approximately perpendicular to the direction of inflow of the cooling water and which is used in particular to divert the flow towards the pump;
- the chamber side walls merge into the rear chamber walls via inclined wall areas.
- the chamber floor is bevelled towards the chamber rear wall.
- longitudinal sheets running perpendicular to the chamber bottom are arranged.
- the interior of the pump chamber is accessible from the outside via a fluidic connection, which is used for the further removal of cooling water or for measuring coolant properties. Cooling water extraction is provided, for example, for extinguishing purposes or for temporary cleaning purposes using cooling water.
- pumps are usually arranged in the pump chamber or in the calming section. However, these act as flow resistance and are often the cause of the formation of surface vortices. With the fluidic connection via the chamber wall, the arrangement of such pumps in the interior is obsolete.
- pipe housing pumps in which the pump pipe is guided through a chamber ceiling of the pump chamber, larger or larger quantities can be additional water above the corner of the chamber. This water leaves the pump chamber through an annular gap between the pump tube and the chamber ceiling.
- the cleaning device like the pump chamber in the inlet area to the pump chamber, has sloping side walls. Furthermore, a cleaning device is preferably arranged immediately in front of the inlet opening of the pump chamber and completely surrounds it. This cleaning device preferably has flow baffles on its side facing away from the pump chamber.
- An alternative embodiment is preferably achieved by designing the pump as a concrete spiral housing pump, the concrete spiral housing forming the chamber ceiling of the pump chamber.
- the concrete spiral housing pump preferably has a suction pipe that projects into the pump chamber.
- the cooling water in the cleaning chamber is cleaned in an operating building with a pump chamber and a pump for cooling water arranged therein, and with a cleaning chamber directly adjacent to the pump chamber, and then flows into the pump chamber at high flow velocity, so that no vortices disturbing the operation of the pump are formed.
- FIG. 1 shows a partial sectional side view through an operating building
- FIG. 2 also shows a partial sectional side view through an operating building with a concrete spiral housing pump
- FIG. 3 shows a top view of a horizontal section through a pump chamber.
- an operating building 2 for a large-scale plant in particular, such as a power plant for generating energy has a pump chamber 4 and a cleaning chamber 6, which adjoin one another directly via a common chamber wall 8.
- the cleaning chamber 6 and the pump chamber 4 are in fluid communication with one another via an inlet opening 10.
- the pump chamber 4 is designed as a so-called covered pump chamber and has a chamber ceiling 28.
- a pump 14 with a pump tube 16 is arranged in the pump chamber 4 and is spaced apart from the chamber bottom 12. This is guided through the chamber ceiling 28 to form an annular gap 29.
- a suction bell 17 is connected at the end to the pump tube 16.
- the pump according to FIG. 1 the pump according to FIG.
- FIG. 2 is designed as a concrete spiral housing pump 14a.
- This has a concrete spiral housing, which is formed by concrete components 19 inserted into the building structure or by the building structure itself.
- a suction pipe 20 with a suction bell 17 attached at the end extends from the concrete spiral housing pump 14a into the pump chamber 4, so that the suction bell 17 is at a height which is favorable for operation.
- a cleaning inlet is located in the cleaning chamber 6 immediately before the inlet opening 10 and completely covers it.
- direction for the cooling water arranged in the form of a filter or a sieve 22. It is designed in particular as a so-called belt machine.
- This has a circulating sieve belt with a plurality of sieve surfaces 24, which are used in the area of the inlet opening 10 for cleaning cooling water and are cleaned in the upper area of the sieve belt machine, for example by spraying.
- the screening device 22 is preferably preceded by further cleaning devices, not shown.
- the cooling water is usually taken from a natural reservoir, reaches the cleaning chamber 6 via an inflow opening 26, is cleaned there and then sucked in by the pump 14 through the inlet opening 10 into the pump chamber 4.
- the operating building 2 is arranged with respect to the water level of the reservoir in such a way that, in the event of a natural fluctuation in the water level between a high water level H and a low water level N, the suction bell 17, that is to say the inflow region of the pump 14, is sufficiently covered with cooling water. If the overlap is too low, the quality of the flow in the pump tube 16 deteriorates. This is particularly true if the water level sinks below the chamber ceiling 28.
- Construction height of the company building 2 so that the manufacturing costs are kept low.
