Description

TECHNICAL FIELD

[0001] The present application relates to the field of biogas power generation, in particular, to a biogas pretreatment device for biogas power generation. BACKGROUND

[0002] Biogas combustion power generation is a biogas utilization technology that appears with the continuous development of large-scale biogas pond construction and biogas comprehensive utilization. It uses the biogas produced by anaerobic fermentation treatment on the engine and is equipped with a comprehensive power generation device to generate electric energy and heat energy. However, the biogas needs to be pretreated for desulfurization and drying before entering the generator set.

[0003] However, the drying agent and the desulfurizer in the drying box and the desulfurizer will lose effectiveness after long-term use, so they need to be replaced. In the current equipment, the drying agent and the desulfurizer cannot be automatically replaced, and manual replacement of the drying box and the desulfurizer is required. Since the drying box and the desulfurizer are relatively large in size, it will increase the physical labor of workers and reduce work efficiency.

[0004] To this end, Chinese patent application No. CN202322682903.X discloses a biogas pretreatment device for a biogas generator set, which includes a desulfurization box and a drying box. The desulfurization box and the drying box are fixedly connected with first ear plates on both sides. The first ear plates are rotatably connected with a bottom plate. The bottom plate is fixedly connected with a second ear plate on the lower surface. The output end of a first hydraulic cylinder is rotatably connected with the second ear plate. The device can desulfurize and dry the biogas, and can replace the drying agent and the desulfurizer in the drying box and the desulfurization box, thereby reducing the physical expenditure of the operator.

[0005] However, the above-mentioned solution still has the following disadvantages. During loading, the drying agent and the desulfurizer are poured into the drying box and the desulfurization box through the box body. However, after being poured, the drying agent and the desulfurizer fall on the bottom plate, which can easily cause accumulation on one side and no drying agent and desulfurizer on the other side, making it difficult to distribute evenly and affecting the drying and desulfurization effect. At the same time, the first hydraulic cylinder drives the bottom plate to rotate downward, causing the used drying agent and desulfurizer to fall. However, some drying agent and desulfurizer still adhere to the surface of the filter screen, affecting the subsequent biogas pretreatment and reducing the practicality of the device. CONTENT OF THE INVENTION
