Ultraviolet ray catalyst used for detecting total organic carbon content in water

Abstract

The invention discloses an ultraviolet ray catalyst used for detecting total organic carbon content in water. The catalyst comprises an ultraviolet ray lamp with a power line, and a fluid channel with a water inlet and a water outlet. The structure of the fluid channel comprises that: a first fixing device is arranged on a first end of a titanium metal sleeve pipe; the water inlet is arranged at the first fixing device, and is connected in a sealed state with the titanium metal sleeve pipe through a sealing ring; a second fixing device is arranged on a second end of the titanium metal sleeve pipe; the second fixing device is connected in a sealed state with the titanium metal sleeve pipe; the ultraviolet ray lamp is centralized and fixed in the inner cavity of the titanium metal sleeve pipe through the second fixing device; the cavity between the titanium metal sleeve pipe and the ultraviolet ray lamp forms a catalyzing chamber with the fluid channel; and the water outlet is arranged on the lower part of a second end of the titanium metal sleeve pipe. The technical effect is that: with a direct irradiation method, organics in water can be sufficiently oxidized into inorganic carbon; and the content of organic carbon can be deduced through testing the content of inorganic carbon. Therefore, measuring accuracy of organic carbon content in water is improved.

Description

technical field [0001] The invention belongs to the technical field of water quality testing equipment, and relates to a catalytic converter, in particular to an ultraviolet catalytic converter for detecting the content of total organic carbon in water. Background technique [0002] Total organic carbon (TOC) is the total amount of carbon contained in dissolved and suspended organic matter in water. TOC is a comprehensive index for rapid verification. It expresses the total amount of organic matter in water by the amount of carbon. It is usually used as an important basis for evaluating the pollution degree of organic matter in water. method, etc.) to convert organic matter into inorganic carbon, and then deduce the content of organic carbon by testing the content of inorganic carbon. The ultraviolet catalyst used in the commonly used ultraviolet oxidation method is as follows: figure 1 As shown, it uses 185nm and 254nm dual-wavelength ultraviolet lamps to irradiate the wa...

Problems solved by technology

[0008] The purpose of the present invention is to solve the technical problem that the existing ultraviolet catalytic converter cannot quickly and fully oxidize the organic matter in water, which reduces the measurement accuracy of total organic carbon content in water. In order to solve this problem, we have designed a The ultraviolet catalytic converter with carbon content uses the direct irradiation method to quickly and fully oxidize the organic matter in the water into inorganic carbon. By testing the content of inorganic carbon, the content of organic carbon is deduced, which improves the measurement accuracy of total organic carbon content in water.
