Dissolved oxygen and temperature monitoring and gas intelligent controller

Abstract

The invention discloses a dissolved oxygen and temperature monitoring and gas intelligent controller which comprises a gas solenoid valve connected to a master controller. One end of the gas solenoid valve is connected with a gas inlet pipe, the other end of the gas solenoid valve is connected with a gas outlet pipe through a gas flowmeter, the master controller comprises a single-chip microcomputer, a detecting sensor module, a control range setting module and a solenoid valve control module, the detecting sensor module, the control range setting module and the solenoid valve control module are connected to the single-chip microcomputer, the solenoid valve control module controls the gas solenoid valve to be opened and closed, and the detecting sensor module is placed in water or air. According to the set control value of dissolved oxygen, the gas channel of gas can be automatically opened and closed, the gas channel is automatically cut off or opened when a measuring value is higher than the upper limit of the control value, and the gas channel is automatically opened or cut off when the measuring value is lower than the lower limit of the control value. The oxygen is really increased or decreased according to needs, the human capital of employees and gas cost are greatly saved, and energy consumption is greatly reduced.

Description

technical field [0001] The invention relates to the field of water quality measurement and control instruments, in particular to an intelligent controller for dissolved oxygen, temperature monitoring and gas. Background technique [0002] Dissolved oxygen in water is one of the most important factors in water, so how to measure and improve dissolved oxygen has become an important topic. [0003] 1. With the development of industry and agriculture, the pollution of the water environment has intensified, and more and more polluted water bodies need to be treated, such as drinking water, sewage, aquaculture water bodies, etc. Oxygenation into water bodies is one of the effective means to alleviate water pollution one. However, in the traditional method, the measurement of dissolved oxygen in water and the increase of dissolved oxygen in water are two independent steps, which cannot realize automatic control, so oxygen cannot be increased on demand, and the cost of use is incre...

Problems solved by technology

In the traditional method, the measurement of dissolved oxygen in water or air and the reduction of dissolved oxygen in water or air are two independent steps, which cannot be automatically controlled, and deoxygenation is a continuous and uninterrupted process that requires precise control. If it is not based on the measured If the dissolved oxygen index is used to carry out the next reaction, it may affect the reaction effect or reduce the deoxygenation effect. Therefore, how to effectively combine the oxygen measurement and oxygen reduction into one, to achieve 24-hour monitoring of water or air Dissolved oxygen, and can effectively reduce oxygen on demand according to the measured value, this is the problem we are currently facing
