Reaction tower capable of controlling biogas stirring amount

Abstract

The invention discloses a reaction tower capable of controlling biogas stirring amount. The reaction tower comprises a box body, wherein a servo motor is placed on the outer side of the middle of the bottom of the box body, the shaft end of the servo motor is upwards placed on a supporting column, the shaft of the servo motor is arranged in a bearing hole in an interference fit mode, the outer side of a bearing is welded to the bottom of the box body, the shaft of the servo motor is matched and fixed with stirring fan blades in the box body through key grooves, a water distribution pipe is arranged above the stirring fan blades, one end of a water inlet bent pipe is welded to the middle position below the water distribution pipe and is communicated with the water distribution pipe, the other end of the water inlet bent pipe is connected with a pipeline of a water inlet through a flange, a heating pipe is arranged on one side above the water distribution pipe and is welded to the box body, and a three-phase separator is welded on the inner wall of the box body above the heating pipe. According to the invention, under the condition of observing a gas flow meter, a reaction rate in the box body of a reaction tower can be controlled through the rotating speeds of a heating pipe and stirring fan blades, the gas output of biogas is limited by controlling an electric valve, and a pressure release valve ensures that the amount of the biogas in the box body is not too large to cause danger.

Description

technical field [0001] The invention relates to an anaerobic reaction tower, in particular to a reaction tower with controllable biogas stirring volume. Background technique [0002] Anaerobic biological treatment of wastewater is an important technology in environmental engineering and energy engineering. It is one of the powerful treatment methods for organic wastewater. In the past, it was mostly used for sludge, organic waste and some high-concentration organic wastewater in urban sewage plants. For the treatment of waste water, ordinary digesters are mainly used in the form of buildings. Due to the disadvantages of long hydraulic retention time and low organic load, its application in wastewater treatment is limited for a long time; the amount of biogas in the existing reaction tower is uncontrollable. As a result, it is difficult to collect and use. When the biogas tank is full, the reaction tower continues to react. If the biogas tower is not discharged in time, there...
