Novel biological desulfurization device for biogas

Abstract

The invention discloses a novel biological desulfurization device for biogas. The novel biological desulfurization device for the biogas comprises a desulfurization tower, wherein the upper end of thedesulfurization tower is in through connection with an air inlet pipe and a nutrient solution delivery pipe, a sealing cylinder fixedly sleeves the end, located in the desulfurization tower, of the air inlet pipe, a movable sealing plate is hinged to the top wall of the sealing cylinder, and the sealing plate is slidably connected with the inner side wall of the sealing cylinder. The novel biological desulfurization device for the biogas has the advantages that an oxygen balance device is added, and through the arrangement of the oxygen balance device, the action of the content of oxygen in the desulfurization tower can be automatically adjusted according to the content of the oxygen in the desulfurization tower, thereby being capable of achieving the effect of saving time and labor; a control device is added, so that when the gas enters the desulfurization tower, the control device can control a delivery pump to work to ensure that gas entering and nutrient solution transporting arecarried out simultaneously, thereby achieving the effect of saving resources.

Description

technical field [0001] The invention relates to the technical field of biological equipment, in particular to a novel biological desulfurization device for biogas. Background technique [0002] In the process of sewage treatment or other industrial production, combustible gases, such as biogas, are produced. Energy is stored in the combustible gas, which can be used for power generation, etc., to save energy, but the combustible gas contains hydrogen sulfide. If the combustible gas is directly burned, Sulfur dioxide will be generated, which will cause great pollution to the environment. [0003] The patent application with the publication number CN108325374A discloses a biogas biodesulfurization method, which consists of the following structures: a desulfurization tower; a nutrient solution delivery pipeline; a nutrient tank; a delivery pump; a nutrient solution circulation return pipeline; pipeline; oxygen supply control valve; water supply control valve; inner ring sleeve...

AI Technical Summary

Problems solved by technology

[0004] However, the present invention also has the following disadvantages: (1) due to the simple structure of the oxygen regulating valve, it can only be adjusted manually every time when adjusting, which is time-consuming and labor-intensive; liquid, which will cause the previous nutrient solution to be unable to contact with the gas, resulting in a waste of resources
