[0020] The utility model will be further described in detail in combination with the drawings.

[0021] Embodiment one, in combination with the drawings Figure 1 A kind of integrated biogas purification device for biogas engineering, including base 1 and base 1 sequentially arranged filter 2, water storage tank 3, condensing tank 4, desulfurizing tank 5, control box;Through above-mentioned component, integrated biogas purification and dehumidification desulfurization treatment can be realized;

[0022] in combination with the drawingsFigure 1 The desulfurization tank 5 is provided with two, which are used alternately; thus, in actual use, one desulfurization tank 5 is used for participating in purification and desulfurization operation; the other is used for desulfurizer regeneration and standing; when the desulfurizer is discolored or the system pressure loss is too large, the other desulfurization tank 5 can be used, which can reduce the time for replacing the desulfurizer, improve the operation efficiency and safety;

[0023] Combining the drawings Figure 1 The filter 2 is connected to the outside of the water storage tank 3 at the end, which can improve the installation stability of the filter 2 and make it not easy to be damaged in the state of being impacted by airflow for a long time;

[0024] Combining the drawings Figure 1 , 2 The filter 2 is connected with the air inlet pipe 6 at the air inlet end and is connected with the air outlet pipe 7 at the air outlet end; the air inlet pipe 6 is connected with the branch pipe 8, the branch pipe 8 is provided with a valve, and the end is connected with the standby filter cartridge 9, the standby filter cartridge 9 is connected with the branch pipe two 10, and the branch pipe two 10 is converged into the air inlet and outlet pipe 7 through the three-way pipe fitting; in the state that the standby filter cartridge 9 is used, the branch pipe 8 and the branch pipe two 10 form a passage, and the filter 2 is closed; in the state that the standby filter cartridge 9 is closed, the valve on the branch pipe 8 is closed; thus, according to actual needs, when the filter 2 has problems such as poor filtering and blocking, the biogas can be diverted into the standby filter cartridge 9, the switching can be realized without stopping the gas, and the operation efficiency can be ensured;
