Photo-catalytic reaction device using ultrasonic for scale prevention and removal

Abstract

The invention discloses a photo-catalytic reaction device using ultrasonic for scale prevention and removal. The device consists of a photo-catalytic reactor and an ultrasonic generator arranged on a base, as well as an electric cabinet; wherein the photo-catalytic reactor comprises a water inlet pipe, a sleeve, a metal mesh, bolts, gaskets, tube terminals, a power cord, a top cover, sleeve flanges, a water outlet pipe, a metal mesh support frame and an ultraviolet tube; a plurality of through-holes corresponding to the inner metal mesh layer are arranged on the outer surface of the sleeve along the axial direction in a bilateral symmetry way, and ultrasonic transducers are mounted at all the through-holes; a cleaning solution box is mounted on the top cover and communicated with the inner part of the sleeve; the ultrasonic transducers are connected to the ultrasonic generator via transmission cable wires; and a draining valve is mounted at the bottom of the sleeve. The invention can prevent the scale from forming in the inner metal mesh during the operating process of the photo-catalytic reactor, meanwhile, the invention can carry out shutdown scale removal on the inner wall of the sleeve of the photo-catalytic reactor and the inner metal mesh, thereby achieving the double effects of preventing the scale from forming and destroying the formed scale.

Description

technical field [0001] The invention relates to a photocatalytic reaction device using ultrasonic waves for anti-scaling and descaling. Background technique [0002] With the in-depth study of photocatalytic oxidation, photocatalysts have been successfully loaded on the surface of photocatalytic metal materials, making more and more photocatalytic reactors suitable for large-scale industrial applications. As the core component of the photocatalytic reactor, the composite photocatalytic metal material has a three-dimensional network structure, and its activity and life are the key factors that determine whether the photocatalytic reactor can be practical. After the reactor treats the water body for a long time, some adsorbates in the water body are preferentially adsorbed on the active part of the catalyst on the metal mesh, forming a particularly strong chemical adsorption bond, so that a large amount of organic pollutants, inorganic ions and inorganic pollutants are adsorbe...

AI Technical Summary

Problems solved by technology

Among them, the scale inhibitor needs to be injected continuously, and it is difficult to control the dosage each time, and the scale cleaning effect is good and bad; and the latter three methods cannot effectively solve practical problems due to high cost or difficult implementation.

Off-line shutdown cleaning is often carried out under the conditions of unplanned shutdown, partial shutdown of the device or switching of various equipment, while various traditional methods, such as high-pressure water jet (mechanical cleaning method) and chemical cleaning agent (chemical cleaning method) etc., it is only a temporary solution, not the root cause, which not only affects production, but also increases unplanned costs, wears and corrodes equipment, pollutes the regional environment, and damages the health of workers, etc.
