AI Technical Summary
Technical Problem
Existing IC anaerobic reactors commonly suffer from blockage of the internal circulation downcomer during operation, which prevents biogas from being discharged normally, posing safety hazards and affecting COD treatment efficiency.
Method used
The liquid level of the gas-liquid separator is monitored by a level gauge. The downcomer is automatically cleared by combining the gas delivery pipe and pressure transmitter. Inert gas is used to clear the downcomer to ensure stable operation of the internal circulation.
Benefits of technology
It effectively avoids the risks of biogas accumulation and leakage, improves the safety and operating efficiency of the sewage treatment system, and enhances the system's stability and treatment effect.

Abstract
This utility model belongs to the field of wastewater treatment and discloses an IC anaerobic reactor, including: a reactor tank with an inlet pipe and an outlet pipe connected to it; a downcomer whose upper end is connected to the liquid outlet of a gas-liquid separator and whose lower end extends into the reactor tank; a level gauge installed in the gas-liquid separator to detect the liquid level; an inlet control valve installed in the inlet pipe to control the opening and closing of the inlet pipe; an outlet control valve installed in the outlet pipe to control the opening and closing of the outlet pipe; a downcomer control valve installed in the downcomer to control the opening and closing of the downcomer; a gas delivery pipe connected to the downcomer and located below the downcomer control valve for introducing inert gas; a gas control valve installed in the gas delivery pipe to control the opening and closing of the gas delivery pipe; and a pressure transmitter installed in the downcomer to detect the pressure of the gas inside the downcomer. This utility model can achieve automatic unblocking of the downcomer, thereby improving safety and treatment efficiency.
