Water quality testing equipment

Abstract

The invention relates to water quality testing equipment. The water quality testing equipment consists of a cooling device and a water quality monitoring device which are connected with each other, wherein the cooling device is connected with a steam header pipe of a boiler; after heat of steam is exchanged and the steam is cooled, condensed water is guided into the water quality monitoring device through a pipeline; the water quality monitoring device consists of three flowing pools which are sequentially connected; the condensed water flows into the water quality monitoring device from a water inlet pipe below one side of the flowing pools, and flows out from a water output pipe above the other side of the flowing pools; a dissolved oxygen concentration sensor, a conductivity sensor and a pH sensor are sequentially arranged inside the three flowing pools. Compared with the prior art, the water quality testing equipment can accurately test the liquid oxygen, the pH and the conductivity of a water sample in the boiler, without influence from outside air.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a water quality testing device. Background technique [0002] In boiler steam, condensed water, and feed water samples, due to the impreciseness of the unit, some air is often brought in, and the air in the boiler cooling water directly affects the test accuracy of conductance and pH, making the test value too large. In order to obtain No oxygen, CO 2 Pure water sample, through such a water sample flow cup, eliminate oxygen, CO 2 Impact. [0003] Chinese patent CN103645290A discloses a water quality online detector, including industrial control LCD screen, MCU unit, light source controller, data collector, power supply module and multi-wavelength optical detection device, by using water quality analysis sensor combined with multi-wavelength optical detection device, a On the one hand, the water quality analysis sensor is used to measure simple water quality ...
