Embodiment Construction

[0031] Such as figure 1 Shown is a gas inlet and outlet structure of a biogas storage cabinet. The gas storage cabinet can be various types of biogas storage cabinets. In this embodiment, the membrane type biogas storage cabinet 11 is mainly used as an example for specific description. The membrane type biogas storage tank 11 is an existing structure, which is mainly composed of an outer membrane, an inner membrane and a bottom membrane which are sealed and connected to each other. The bottom membrane is located at the bottom of the membrane type biogas storage tank 11 and has a circular shape. A pipe 1 communicates with the interior of the inner membrane from the center of the bottom film, and the top of the pipe 1 forms a sealed connection with the bottom film through a flange 7. The connection structure between the bottom membranes is the same. The commonly used structure is to fix a flange 7 at the center of the bottom membrane and ensure the sealing of the connection, and...

Abstract

The invention specifically relates to improvement of an existing marsh gas storage cabinet gas outlet and inlet structure, and aims at providing a marsh gas storage cabinet gas outlet and inlet structure. The marsh gas storage cabinet gas outlet and inlet structure comprises a gas pipe and a condensate water discharge pipe which are communicated with a gas storage cabinet, wherein the gas pipe and the condensate water discharge pipe are communicated with the interior of the gas storage cabinet from the bottom of the gas storage cabinet through a pipeline, and a marsh gas sealing structure is arranged at the tail of the condensate water discharge pipe. The marsh gas storage cabinet gas outlet and inlet structure is connected with the gas storage cabinet only through one pipeline, and the pipeline simultaneously has air suction, air exhaust and condensate water discharge functions, and therefore the number of pipelines connected with the gas storage cabinet is decreased, gas tightness of the gas storage cabinet is guaranteed, and engineering cost is saved. The invention further aims at providing a marsh gas storage cabinet gas outlet and inlet connection method. The marsh gas storage cabinet gas outlet and inlet connection method includes steps: performing heat preservation treatment on the pipeline and burying the pipeline below a lower line of a frozen soil layer. According to the marsh gas storage cabinet gas outlet and inlet structure and the marsh gas storage cabinet gas outlet and inlet connection method, the problem that the condensate water pipeline is frozen due to over low temperature is effectively solved.

Description

technical field [0001] The invention belongs to the field of biogas production, and in particular relates to the improvement of the gas inlet and outlet structure of the biogas storage cabinet and the connection method of the gas inlet and outlet of the biogas storage cabinet. Background technique [0002] Membrane biogas holder is a special equipment for biogas storage in biogas projects and sewage treatment projects. The gas storage cabinet is used to transport the air in and out through the air pipe, and discharge the condensed water through the condensed water pipe. Existing gas storage tanks have a variety of design styles for biogas inlet and outlet and condensate discharge. One air pipe enters and exits air at the same time, and one condensate pipe is a double-pipe design. The above design structures all adopt the method of setting the condensate pipe and the gas pipe separately, which will cause some problems, such as: 1. The gas storage cabinet must ensure a high ...
