Definitions

  • reaction space is part of a mobile device and the mobile device can be introduced and removed into the pipeline in which the system to be treated is located, regardless of the pressure condition of the pipeline with the system to be treated,
  • reaction space is after using the mobile device in the pipeline with the system to be treated
  • the reaction space is part of a mobile device, which can be spent regardless of the pressure state of the pipeline in this and removed again.
  • the reaction space in which the CIO 2 is produced is part of a mobile device and, after being introduced into the pipeline, is completely surrounded by water or an aqueous system and this is at the same time the system to be treated.
  • the relocation of the place of origin of the chlorine dioxide, out of the personal premises and the storage location of the chemicals used, significantly increases security. Leaks, even explosions of the reaction space, are practically neutralized by the large volume of systems to be treated.
  • the reaction space can be introduced into a pipeline through which the system is to be treated and under pressure, and be removed therefrom, without the transport and thus the use of the system to be treated in the pipeline Interrupt piping.
  • the reaction space is preferably located in the main pipe of the system to be treated and not in a bypass line to the main line, which is spatially isolated by upstream and downstream of the lying in the bypass line addition of chlorine dioxide to the system to be treated shut-off.
  • the reaction space is part of a mobile device, which preferably consists of a piston-shaped tube in which the reaction space is located, and which mobile device has a reaction space outlet and supply lines for the reactants and optionally dilution water ,
  • the mobile device, preferably the piston-shaped tube, with the reaction space is guided and moved into a guide channel, preferably a cylindrical outer tube, which, shut off by a shut-off against the pipeline to the system to be treated, access to the pipeline with the system to be treated Has.
  • the obturator can be opened and the mobile device, preferably the piston-shaped tube with the reaction space can in the pipeline with the system to be treated be introduced.
  • the feed lines for the reactants and optionally dilution water are preferably passed from above into the mobile device and into the reaction space.
  • the supply lines outside the reaction space, preferably the reactor are led to the entrance of the reaction space, for example from the side or from below.
  • Reaction space can only increase up to the value which is exerted by the surrounding system to be treated on the reaction space.
  • the concentration of the chlorine dioxide forming in the reaction space, preferably in the reactor, can be adjusted in combination with pressure and temperature of the surrounding system to be treated so that the solubility limit of chlorine dioxide in the system to be treated is not exceeded. As a result, the formation of a 2-phase system can be prevented by a forming chlorine dioxide gas phase.
  • Preferred in this invention is the hydrochloric acid-chlorite process (1.).
  • the feed chemicals (reactants) of alkali metal chlorite salt preferably sodium chlorite in aqueous solutions of 3.5% to 40% can be present.
  • the acid is preferably hydrochloric acid in a concentration of 3.5% to 42%.
  • concentrated feed chemicals are used and the hydrochloric acid chlorite process (1) is used.
  • concentration of hydrochloric acid is then about 33-42% and that of the sodium chlorite solution is about 25-40%.
  • a dilution of the feed chemicals before or in the reaction space, preferably reactor, is not carried out.
  • the feed chemicals especially acid and chlorite are separated as an aqueous solution, as described above, driven by autogenous pressure of the solutions or with the help of the pump in the reaction chamber and reacted.
  • the reactants are used as concentrated solutions and it is dispensed with the use of dilution water, so that the chlorine dioxide concentration at the end of the reaction chamber, preferably at the reactor outlet, or the derivative, sets to greater 80 g / 1 solution.
  • dilution water can be used to adjust the chlorine dioxide concentration at the end of the reaction space, preferably at the reactor outlet, or the discharge, between greater than 3 g / l solution preferably greater than 26 g / l solution and more preferably greater than 80 g / l solution.
  • the device for carrying out the method according to the invention essentially comprises suitable devices and apparatuses.
  • the reaction time in the reaction space can vary. As the concentration of reactants in the reaction space increases, the optimum residence time is reduced. When a solution having a chlorine dioxide concentration of 20 g / l is prepared, the average reactor residence time is about 60 minutes to 4 minutes, preferably about 4 to 6 minutes, to achieve a yield of about 85%. If the chlorine dioxide concentration according to the particularly preferred embodiment increases to greater than 80 g / l, then the average reactor residence time is about 0.1 minutes to 1.5 minutes, preferably 0.3 to 0.6 minutes, particularly preferably about 0, 4 minutes for a 95% yield.
  • the method according to the invention can be carried out, for example, by means of the devices shown in FIGS. 1 and 2a and 2b.
  • the concentration of the resulting chlorine dioxide solution is adjusted to greater than 3 g / l, preferably greater than 26 g / l and particularly preferably greater than 80 g / l.
  • the preferred variant consists of allowing the reactants to react in the reaction space without dilution with water (delivery pump 7 switched off, dilution water 6).
  • the reaction space preferably the reactor
  • this mobile device has a reaction space outlet and feed lines for the reactants and optionally dilution water, and with the movement device 16, preferably a threaded rod, in the guide channel 13, preferably a cylindrical outer tube 13, can be pushed and moved.
  • the obturator 12 is closed, so that no system to be treated can penetrate into the interior of the guide channel 13.
  • the preferred variant is to reduce the volume of the reaction space, preferably the reactor, to a maximum.
  • the concentration of chlorine dioxide solution at the reaction chamber outlet 8 is set to greater than 80 g / l.
  • the guide channel 13 is preferably mounted in a 12 o'clock or 6 o'clock position on the system-leading pipe 11. Regardless of the installation location of the guide channel 13, the reaction space, preferably the reactor, should preferably be arranged such that it is located at the bottom relative to the reaction space outlet. The advantage is that gaseous components can leave the reaction space.
  • the preferred variant consists in allowing the reactants to react in the reaction space without dilution with water (switched-off feed pump dilution water 6).
  • the concentration of the resulting solution at the reaction space outlet 8 can be greater than 9 g / l, preferably greater than 26 g / l and particularly preferably greater than 80 g / l chlorine dioxide, per liter increase. In this preferred variant, it is advantageous to maximally reduce the reactor volume.
