Definitions

  • the invention relates to a compressed gas processing system for processing compressed gas with the features of the preamble of claim 1.
  • Devices of the type mentioned are known from the prior art, for example DE 10 2018 118 206 A1 .
  • the device described therein makes it possible to provide processed compressed gas to a consumer, with the compressed gas being humidified before it is made available.
  • An improved spraying result can be achieved with such a device, particularly under ideal conditions.
  • the compressed gas conveyed, for example, in a compressed gas line is subject to the influence of ambient conditions (air pressure and temperature). This can lead to undesired heating or cooling of the compressed gas line and compressed gas, so that the humidified compressed gas can condense in the compressed gas line. This results in the risk of drop formation.
  • Approaches to a solution using electrical heating spirals for hose arrangements are only suitable for special applications, with use in explosion-protected areas (“Ex-protection area”) being problematic and possibly not possible at all. In this respect, there is a need for optimization.
  • U.S. 5,000,624A discloses a compressed gas processing plant with features of the preamble of claim 1.
  • the invention is based on the object of making it possible to provide compressed gas with a high and consistent quality in a compressed gas treatment plant with simple structural means. It is desirable here that condensation and the formation of drops from humidified compressed gas can be avoided.
  • the invention solves this problem by means of a compressed gas treatment system with the features of claim 1.
  • the compressed gas processing system is used for processing compressed gas.
  • the compressed gas processing system has an input for connecting a compressed gas source and an output for providing processed compressed gas, for example for a spray device.
  • the inlet and the outlet are flow-connected, and a humidification device ("mixing chamber") for humidifying the compressed gas by means of a liquid, for example demineralized water, is arranged in the flow connection.
  • the compressed gas treatment system is characterized in that the compressed gas treatment system has a heating device for heating a liquid (heat carrier), the heating device having a flow connection for dispensing heated liquid and a return connection for feeding in returned liquid.
  • a heated liquid can be provided which can be used to control the temperature of the compressed gas.
  • a hose arrangement with a compressed gas line and a fluid line for temperature control of the compressed gas can be connected to the compressed gas processing system (hose heating).
  • hose heating A liquid-based hose heater is thus created.
  • the risk of condensation and the formation of drops in the compressed gas line is thus significantly reduced.
  • Sufficient explosion protection can be achieved. Due to the high and consistent quality of the Compressed gas, better spraying results can be achieved, e.g. better coating or painting.
  • the flow connection, the return connection and the outlet are arranged adjacent to one another in a (outlet-side) connection area of the compressed gas processing system (adjacent arrangement in the connection area, e.g. a connection terminal).
  • a connection terminal e.g. a connection terminal
  • a hose arrangement (“hose pack") can be provided for the (outlet-side) connection to the compressed gas processing system, the hose arrangement having a compressed gas line and a fluid line for temperature control of the compressed gas line (or of compressed gas contained in the compressed gas line).
  • the fluid line is arranged on or in the compressed gas line and extends along the compressed gas line. This allows (liquid-based) hose heating to be implemented, with the risk of condensation and droplet formation being reduced. This favors a coating result, for example.
  • the compressed gas line can be connected to the outlet (to provide processed compressed gas) and the fluid line can be connected to the flow connection and the return connection of the compressed gas processing system.
  • the compressed gas line (on the connection-side end) can have a connection element for connection to the outlet of the compressed gas treatment system (compressed gas connection).
  • a connection element for connection to the outlet of the compressed gas treatment system (compressed gas connection).
  • the compressed gas line can also have a connection element at the free end.
  • a consumer for example a coating gun, can thus be connected to the free end of the compressed gas line.
  • the connection element can be a coupling plug, a coupling or a screw connection.
  • the fluid line can have (at one end) a first connection element for connection to the flow connection and (at the other end) a second connection element for connection to the return connection of the heating device.
  • the connection element can in each case be a coupling plug, a coupling or a screw connection.
  • the compressed gas line and the fluid line can be routed into one another (line in line or tube in tube).
  • one line can be arranged radially inside the other line, it being possible for the central longitudinal directions of the lines to be arranged parallel or coaxially to one another.
  • the compressed gas line can be arranged radially inside the fluid line or the fluid line can be arranged radially inside the compressed gas line.
  • the compressed gas line can extend along a longitudinal direction (e.g. central longitudinal direction) and the fluid line can be guided helically on or in the compressed gas line, at least in sections.
  • a longitudinal direction e.g. central longitudinal direction
  • the fluid line can be guided helically on or in the compressed gas line, at least in sections.
  • the fluid line can have an advancing section and a returning section, with the advancing section extending from the connection-side end, in particular from the first connection element, along, in particular parallel, to the compressed air line to the free end of the compressed air line, and with the returning Section helically (heating coil) on or in the compressed gas line to the connection-side end, in particular to the second Connection element extends.
  • the area at the free end of the hose assembly is heated the most, since heated liquid is fed through the supply line quite quickly to the free end and from there through the helical winding (gradually) back to the connection end.
  • the leading section merges into the returning section at a reversal point.
  • the reversal point is preferably as close as possible to the free end of the compressed gas line or the hose arrangement.
  • the helical winding can in particular be designed as a helix, which rises with a predetermined pitch (pitch) per winding or revolution.
  • the fluid line or the returning section can have a number of areas in which the helical windings are each wound with different densities.
  • the helix can have a number of regions in which the pitch or the pitch of the helix is different.
  • the helical winding may have a first pitch in a first region and a second pitch in a second region, which is greater than the first pitch. Different temperature zones can thus be formed by varying the winding density along the compressed gas line.
  • the second pitch may be greater than the first pitch by 5 percent or more.
  • the fluid line or the returning section at the free end of the compressed gas line can have an area in which the helical winding has the highest density, and therefore has the shortest pitch. A temperature zone with the highest temperature is thus created at the free end. In this way, the risk of condensation in the compressed gas line at the free end can be kept to a minimum.
  • the heating device can advantageously have a heating element, a pump, a vent and/or a pressure equalization element (pressure equalization tank).
  • the heating element can heat the carrier medium (liquid, e.g. water) in the supply unit.
  • the heating element can be designed as an electric heating element, heat pump heating, wood heating (wood chips or pellets) or solar heating.

Switches, sensors and/or actuators contained in the compressed gas treatment system can be connected to the controller wirelessly (radio, WLAN or Bluetooth) or wired (electrical or electronic connection).
  • the humidification device can be supplied with liquid by means of a (pressurized) liquid reservoir, with the pressure processing system being set up in such a way that if no compressed gas is removed at the outlet (compressed gas connection), the liquid supply to the humidification device is stopped. This counteracts excessive humidification of the compressed gas. This reduces the risk of condensation and droplet formation downstream of the humidification unit.
  • the compressed gas treatment system can be set up in such a way that when compressed gas is removed at the outlet (compressed gas connection), the liquid supply to the humidifying device is activated.
  • a flow switch can expediently be arranged in the flow connection (flow connection between input and output), which determines whether compressed gas is being removed at the output.

  • a drop separator can advantageously be arranged in the compressed gas line of the hose arrangement. In this way, it is possible to prevent liquid droplets from being released, which is undesirable per se, by collecting them in the droplet separator.
