Definitions
- the invention relates to a radial fan with laminar flow element and bypass.
- the radial fan has a housing and an impeller arranged therein, an air inlet and an air outlet, a pressure space being formed between the air inlet and the air outlet.
- Radial fans of this type are often used in burners for domestic technology. In the case of such burners, it is particularly necessary, if the system operates according to the electronic compound principle, that the system parameters are recorded as precisely as possible in order to adapt the respective control exactly to the required requirement.
- Such combustion plants are usually equipped with a pneumatic system, i.e. Valves are controlled pneumatically, the control pressure being provided by the pressure generation of the impeller or being tapped at a corresponding point at the air inlet. This means that a minimum working pressure must always be maintained in order to apply the necessary control forces. This means that a larger power consumption is required for a drive motor than would be necessary to only provide the desired heating output.
- a pneumatic system i.e. Valves are controlled pneumatically, the control pressure being provided by the pressure generation of the impeller or being tapped at a corresponding point at the air inlet.
- control commands for the respective valves are not transmitted to the valves as pneumatic impulses, but as electrical impulses.
- the electrical impulses are controlled by a computer unit on the valves.
- the respective control signals depend on the power called up, and this in turn can specify a speed for the drive motor.
- the amount of fuel to be added depends on controlled the air mass, which is detected by a suitable sensor. In the same way, the fuel mass, usually gas, can also be recorded and admixed with respect to the quantity in a computer-controlled manner.
- the invention is based on the object of specifying a radial fan of the type mentioned, in which the most accurate possible mass quantity measurement for subsequent control according to requirements is achieved in a cost-effective manner.
- a laminar flow element is arranged in front of the air inlet and has a sensor in a bypass formed therein for detecting at least one parameter of the medium flowing through the air inlet.
- the arrangement of a laminar flow element in front of the air inlet ensures that the inflow is quasi laminar, regardless of the speed and other device parameters.
- the special placement of the sensor for detecting a parameter of the medium flowing through the air inlet enables a largely trouble-free detection of the desired parameters.
- the laminar flow element consists of an arrangement of flow channels which are enclosed by an outer cylinder. It can advantageously be provided that the flow channels are formed in an insert which is inserted in the outer cylinder, the bypass being formed between the two components. In this way, simple processing and manufacture of the component is possible.
- the bypass has an inlet gap and an outlet gap, which are each formed between the insert and the outer cylinder.
- the gap formation between two different components makes it possible in a simple manner to set the volume flow through the bypass in relation to the volume flow in the main flow to the desired level.
- the provision of a gap as an inflow for the bypass ensures that laminar flow is fed to the sensor, so that the most accurate measurement results are achieved.
- the entry gap is in flow connection with an inflow opening of the tongue element, advantageously one behind the entry gap Calming chamber is provided for calming the air flow, and the sensor is arranged in a sensor channel which is in flow connection with the calming chamber via an inflow and an outflow opening. This fluidic measure achieves a maximum of calming for the medium to be measured, which increases the quality of the measurement result even more.
- An inflow for a further medium is formed between the laminar flow element and the air inlet of the housing, this inflow advantageously being evenly distributed over the circumference of the air inlet. This measure ensures the best possible mixing of the air with the combustion medium.
- the further medium is advantageously supplied via a Zelement Oberselement, in which a sensor for tapping predetermined parameters is also provided.
- This sensor is also advantageously arranged in a bypass which extends between an insert and an outer ring. The rest of the training with the calming chamber and flow connection of the bypass channel is similar to that in connection with the bypass in the laminar flow element.
- FIG. 1 is a sectional view of a schematic representation of a part of a radial blower with housing, impeller, air inlet and supply element for further media,
- FIG. 3 shows a representation of the detail II in FIG. 1,
- FIG. 4 shows a representation of the detail III in FIG. 1,
- Fig. 6 shows an alternative embodiment in section acc. Fig. 1,
- Fig. 7 is an illustration of a section along the line A-A in Fig. 6 and
- FIG. 6 shows an illustration of the detail V in FIG. 6.
- 1 shows an axial section through the air inlet area of a radial fan 1 according to a first embodiment.
- the radial fan 1 has a housing 2 with an impeller 3 arranged therein.
- an air inlet 4 and, shown schematically, an air outlet 5 for the radial delivery of a mixture of media are formed essentially centrally on a side wall of the housing 2.
- the air inlet 4 is provided with an inlet bend.
- a laminar flow element 7 is arranged in front of the air inlet 4.
- the laminar flow element has an arrangement of flow channels 10, which are formed by a multiplicity of passages formed in the laminar flow element 7. These passages can be circular, but can also have any other suitable cross-sectional shape.
- the flow channels 10 are formed in the illustrated embodiment in an insert 12 which is inserted into an outer cylinder 11.
- the outer cylinder has a circumferential inner rib 28 on which the insert 12 rests with a shoulder 29.
- a bypass 8 is formed between the inflow opening 4 ′ of the laminar flow element and the outflow region 29 of the laminar flow element.
- a sensor 9 is provided, by means of which the desired parameter of the medium flowing through the bypass is tapped as a reference value for the medium passing through the laminar flow element.
- the bypass has a design which leads to a particular calming of the medium flow, particularly in the area of the sensor.
- the bypass is formed in the flow direction by an inlet gap 13, a first settling chamber 15 ′, an inflow opening 17, a sensor channel 16, an outflow opening 18, a second settling chamber 15 ′′ and an outlet gap 14. 2 to 5, details I to IV of FIG. 1 are shown enlarged. Detail 1 shows the entrance area of the bypass 8.
- the outer cylinder 11 has at its upper free end an inward shoulder 11 'running around the entire circumference.
- the laminar flow element 7 does not adjoin the shoulder 11 'of the outer cylinder 11, but instead forms with its upper end face 7' and the opposite surface 11 "of the shoulder 11 'a circumferential annular gap which subsequently closes the flow path of the calming chamber 15 '.
- the calming chamber 15' branches off in the upper area of the sensor channel 16 at an inflow opening 17.
- a calming chamber 15 is in turn formed, which extends over the outflow opening 18 is in flow connection with the sensor channel 16.
- the calming chamber 15 'in turn is in flow connection via the outlet gap 14 with the air passage in the outflow region 29 of the laminar flow element.
- the outflow region 29 is narrowed to form a nozzle 30. This nozzle 30 reduces the cross section of the outflow area to the cross section of the air inlet 4.
- the sensor 9 is arranged at a suitable point in the sensor channel 16.
- the sensor 9 can be set up to tap different parameters of the flowing medium, for example temperature and flow velocity.
- the immediate vicinity of the outflow gap 14 to the nozzle 30 in the outflow area ensures, as a result of the pressure difference, that a continuous flow in the bypass is obtained.
- the senor 9 is arranged on an insert 9 ′ which is inserted into a corresponding recess in the outer cylinder 11.
- the recess in turn opens towards the sensor channel so that the sensor can come into direct contact with the flowing medium.
- the nozzle 30 ends at a predetermined distance in front of the air inlet 4 of the housing 3. Between the nozzle 30 and the air inlet 4 there is a circumferential annular gap which is in flow connection with a supply element via an inflow channel 19 20 stands for another medium.
- the gap formed between the wall of the nozzle 30 and the air inlet 4 is preferably wider on the side facing away from the feed element 20 than on the side facing the feed element.
- the additional medium in the present case fuel gas, is supplied via a feed element 20.
- the feed element 20 has a connection 31 for a gas line. This connection is in flow connection with a cylinder ring 32, in which an inner ring 33 is inserted.
- the feed element 20 is also equipped with a sensor 21 which is arranged in a bypass 22.
- the bypass design essentially corresponds to the design as described in connection with the laminar flow element 7.
- the bypass 22 thus essentially consists of an inlet gap 26 which is located in the region of the transition between the connection 31 for the gas line and the inner ring 33.
- An upper calming chamber 23 ′ adjoins the inlet gap 26, to which an inflow opening 24 for the sensor channel 35 connects in the upper region.
- the sensor channel 35 In its lower region, the sensor channel 35 is in flow connection with the lower settling chamber 23 "via an outlet 25.
- the lower settling chamber 23" is in flow connection with the outflow opening 36 via the outlet gap 27.
- the outflow opening 36 merges into the inflow channel 19, which directs the second medium to the air inlet 4 of the housing in the manner described above.
- the inflow channel 19 of the further medium does not open into the area of the air inlet 4 or the nozzle area of the air inlet via an annular gap that widens and decreases evenly over the circumference, but rather via a plurality of openings 19 ′.
- the openings 19 ' are evenly distributed over the circumference, but have a larger passage cross section with increasing distance from the feed element 20. In this way it can also be ensured that a uniform mass flow of the gas is supplied to the pressure chamber over the circumference of the air inlet 4.
- the invention is not limited to the illustrated and described forms of training.
- only one sensor is provided in the exemplary embodiment shown, but several sensors can be arranged for more precise detection over the scope of the laminar flow element, the measurement result of which is correspondingly evaluated in a computer and the inflow of gas is regulated accordingly.
