Definitions

  • the invention relates to a blower device for conveying at least one medium, wherein the device comprises at least one blower with housing, a nozzle and a sensor. Furthermore, the invention relates to methods for controlled operation of the blower device, wherein by the sensor, the mass of the medium flowing through the nozzle is measured, the measured values are passed to a control electronically and this adjusts the speed of the fan such that the desired values are achieved at the sensor, wherein at the same time a second, the nozzle supplied medium is adjusted pneumatically in a corresponding manner.
  • the invention is directed to mixing blowers for conveying and mixing combustible media with air, which usually promote the combustible mixture to a downstream burner.
  • blowers are preferably used in heating technology, since they ensure a good premixing of the fuel with air.
  • both pneumatic and electronic control systems are known in the art, but each of which are not without disadvantages in the adjustment of the mixing ratio.
  • premixed blowers for gas burners many influencing parameters have to be taken into account in order to ensure the correct mixing ratio of air and gas (air ratio lambda), whereby the fast and correct adjustment of the air ratio is of high importance for a low-emission combustion with high efficiency.
  • the pneumatic composite is characterized in that valves are pneumatically controlled, wherein the control pressure is provided by the volume flow generated in the blower and at a corresponding point, for example, at the air inlet of the blower tapped.
  • the control of the valve leads to an amount of gas, which is then adapted to the amount of air sucked by the fan and mixed.
  • the higher the negative pressure the farther the valve opens and the larger the amount of gas supplied.
  • the negative pressure depends on the amount of air taken in per unit time and the flow velocity of the air. The relationship between air pressure and flow velocity is known from the Bernoulli equation.
  • the pneumatic composite When using the pneumatic composite in gas heaters, a certain speed is set on the gas blower to achieve a given heating power, and adjusted by the pneumatic composite, the desired air-gas mixture. This mixture is fed to the burner and burned. The relationship between heating power and speed of the impeller is stored in the controller.
  • the pneumatic composite is characterized by the simplicity of its components, which are mainly formed as passively controlled by the fluid mechanics elements.
  • a disadvantage of the pneumatic composite is that the fan speed to achieve a given heating power can be influenced by various conditions. In particular, changing air pressures or temperatures of the intake air can lead to significant deviations of the heating power.
  • the electronic composite was developed, inter alia, in the German patent DE 10 2004 055 715 B4 is disclosed. From this document a method for setting operating parameters of gas burners is known in which by means of an air mass meter, the supplied air mass is detected independently of geodetic influences and is controllable. Furthermore, a sensor for measuring the temperature generated is provided to electronically detect all conditions and to set the correct mixing ratio (lambda) independent of external factors, such as the quality of the heating gas ideal.
  • EP 1 243 857 A1 discloses an electronic composite fan wherein the combustion air / combustion medium ratio is dependent the desired heating capacity is adjusted.
  • the DE 103 49 344 B3 discloses a blower with an air flow sensor in a bypass of a flow straightener.
  • the blower device should be cheaper compared to the electronic composite and still be able to compensate for pressure fluctuations of the supplied medium.
  • the area of action of the nozzle in this case encompasses every area to which the flow modified by the nozzle (for example flow velocity, pressure) acts.
  • the invention is significantly simplified and omitted in an advantageous manner as far as possible on expensive and rule- or tax-intensive electronic elements. For example, no electronic detection of the second medium - the gas volume flow - as well as electronic control of the gas valve is needed, as taught in the prior art.
  • the invention finds particular application for mixing blowers for use in heating technology, wherein air is drawn in as the main flow, and fuel gas is supplied and admixed via a feed element.
  • the invention is essentially a pneumatic composite system which electronically detects the air mass of the main air flow includes and can provide mass balance via a controller or regulation.
  • the blower device according to the invention is designed to convey at least one medium, wherein the at least one medium is preferably air.
  • any sensor element which is suitable for measuring one size or several sizes, which stand alone or together in clear relation to the mass flow flowing through the nozzle.
  • the mere measurement of the volumetric flow is not sufficient, and would only be possible if other measured variables, such as the air density, were detected and a conversion device would be provided which calculates the air mass from the measured variables.
  • the amount of air delivered by the blower is stable and only dependent on the speed.
  • a sensor for direct or indirect determination is sufficient in this case, taking into account the speed control.
  • the air mass can be measured indirectly by measuring, for example, the following parameters in sound velocity, density, Doppler effect, heat capacity or thermal transport performance, barometric pressure, ionizability, speed of light, oxygen isotope concentration, electromagnetic or magnetic permeability, absorption coefficient for certain electromagnetic or mechanical waves and all other variables, which are mainly related to the density of the air.
  • the blower device may additionally comprise an electronic evaluation unit which evaluates the sensor signal and converts it into an electronic signal that can be assigned to the mass flowed through. The transmission of signals is described in more detail below.
  • the nozzle has an additional channel through which at least a portion of the at least one medium (air) flows, wherein the sensor is arranged in the additional channel.
  • the nozzle may also have at least two supply lines for the at least one medium (air), wherein the first supply line comprises the main current, and the second supply line is channel-shaped and the sensor is arranged in its interior. The arrangement of the sensor in a channel-shaped second supply line or an additional channel arranged on the nozzle, a sufficient proportion of the total current flows through the sensor to determine the mass flow uniquely.
  • the nozzle is designed as a Venturi nozzle and arranged in direct connection at the inlet of the housing of the blower, ie, the Venturi nozzle upstream of the fan in the flow direction to the resulting according to the Bernoulli Eisenung in the Venturi nozzle higher velocities of the flow already in the inlet to use the blower.
  • the use of a Venturi nozzle is also advantageous, since in the mass flow is well controlled and thus a measurement by the sensor is easily possible.
  • the mass flow in the additional channel or in the second supply line is subject to the effective range of the Venturi nozzle and is adjusted in particular by the negative pressure generated in the Venturi nozzle, so that there is a direct relationship to the main mass flow through the Venturi nozzle itself and from the measured value of the mass flow in the supply line or the additional channel to close the mass flow in the entire Venturi.
  • an additional channel When using an additional channel is also advantageous if it extends substantially parallel over a predetermined portion of the nozzle and opens into a region in the nozzle, which lies in the flow direction in front of a nozzle portion in which the cross section of the nozzle is minimal.
  • the partial flow guided in the additional passage is consequently returned to the main flow flowing inside the nozzle in an area in front of the narrowest cross section.
  • the invention further provides that the nozzle has a supply element, via which a second medium is supplied by means of the negative pressure generated by the nozzle, wherein the supplied amount of the second medium is controlled solely by the pressure difference due to the negative pressure of the nozzle.
  • gas is preferably used as the second medium.
  • the supply element is preferably designed as a gas line which has a gas valve which controls the amount of gas supplied depending on the open position.
  • the negative pressure generated by the nozzle can act directly or indirectly on the gas valve and ensure a wide open position of the gas valve at a higher negative pressure and a more closed position at a lower negative pressure. On additional electronic measuring or control devices of the gas valve can thus be dispensed with.
  • the senor is electronically connected to a controller or regulation and can transmit the measured parameters of the at least one medium as values to the controller via an electronic signal line.
  • the sensor further detects the value of the air mass flowing through the nozzle per unit time, preferably via an optical fiber line to the controller or controller.
  • the blower device can be controlled both by means of a control and controlled by a control, wherein in a first alternative, the controller is adapted to control the speed of a blower fan of the blower in dependence on the value of the parameter measured by the sensor, in an alternative Design of the blower is equipped with a control that is designed to control the speed of a blower fan of the blower depending on the value of the parameter measured by the sensor until the measured value corresponds to a setpoint stored for the control.
  • the advantage of controlled operation is that, after a change in the air mass flow, the respective new mass value measured by the sensor can be checked by means of a variation of the rotational speed of the fan of the fan and returned to the controller. In the case of the control, only the new speed value is controlled, without there being a check of the actually achieved mass flow.
  • a characteristic which determines the speed of the impeller of the fan in dependence on the required heating power of the burner when the blower according to the invention, as it preferred is designed as air and gas premixing radial fan for burner.
  • the pre-mixing can be done by the housing upstream of the nozzle or additionally or additionally within the housing of the blower itself.
  • the operation of the blower is regulated, whereby in the area of action of the nozzle attached to the inlet of the housing, for example in an additional channel, the mass flow sensor measures the value of the air mass flowing through the nozzle.
  • the value measured by the mass flow sensor is sent to the control via an electronic signal line, whereupon the control regulates the speed of the fan taking into account the measured value such that the value measured by the sensor is stored in one of the control Setpoint corresponds.
  • the method is characterized in that the air mass flowing through the nozzle generates a certain negative pressure, which pneumatically determines the opening position of a gas valve and thus a second medium supplied to the nozzle, so that the regulation of the air mass flow via the change in the speed of the impeller directly to a corresponding change in the supplied gas mass leads.
  • a controller is used instead of a control, in which case no control takes place until the value measured by the sensor corresponds to a desired value stored for the control, but only a predetermined speed value is activated. The remaining process steps are identical to the control method.
  • the elements of the blower device are designed such that the control method according to the invention a pneumatic change of the supplied mass of the second medium (gas) leads, which is in linear dependence on the supplied mass of the first medium (air) and essentially simultaneously with changing the mass of the first medium by varying the speed.
