Temperature monitoring device for active toxic wastewater inactivation tank

Abstract

The invention discloses a temperature monitoring device for an active toxic wastewater inactivation tank. The temperature monitoring device comprises an inactivation tank (1), an electric heater (2),a control line (3), an industrial PC (4) and three temperature sensors (5), wherein the three temperature sensors (5) are respectively arranged at the middle position of the left portion of the inactivation tank (1), the middle position of the top of the inactivation tank (1) and the middle position of the right portion of the inactivation tank (1), the electric heater (2) is arranged at the bottom of the inactivation tank (1), and the electric heater (2) and the three temperature sensors (5) are respectively connected with the industrial PC (4). The temperature monitoring device is high in temperature measurement precision, good in disinfection and sterilization effect, safe and reliable.

Description

technical field [0001] The invention relates to the field of biological wastewater treatment, in particular to a temperature monitoring device for an inactivation tank of active and poisonous wastewater. Background technique [0002] In the process of biopharmaceutical production or scientific research experiments, a lot of live toxic wastewater will be produced. These live toxic waste water must be sterilized at high temperature, and then, after cooling, they can be discharged to the next level of sewage treatment system. In order to achieve the process requirements Need temperature, the heating temperature must be well controlled, the existing control method is to use a temperature sensor placed in the middle of the top of the inactivation tank, but this method has the following disadvantages: 1, due to the large volume of the tank, it may be due to uneven heating , leading to poor temperature measurement accuracy; 2. When the temperature sensor is damaged and fails, it wi...
