[0016] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example 1

[0019] Figure 1-Figure 2As shown: a biogas pipeline emptying antifreeze device, including an emptying pipe 2 connected to each processing system pipeline 1, the emptying pipe 2 is L-shaped, one end of the emptying pipe 2 is fixed on the processing system pipeline 1 in the vertical direction, and the other end of the emptying pipe 2 passes through the sewage well 4 in the horizontal direction and extends to the inner cavity of the sewage well 4, and the end of the emptying pipe 2 away from the processing system pipeline 1 is installed with an emptying valve 3, and the emptying valve 3 is installed along the same straight line, a sewage pump 5 is installed at the bottom of the sewage well 4, and a gas alarm is installed in the sewage well 4;

[0020] When the biogas treatment system is in operation, in order to meet its normal operation, multiple groups of pipelines are set up, such as biogas pipes, tap water pipes, fire water pipes, compressed air pipes, etc. Therefore, an L-shaped drain pipe 2 is installed under each pipeline to artificially create a low point, so that the residual moisture in each pipeline can be discharged into the drain pipe 2 under the action of gravity, and discharged along the drain pipe 2, discharged into the sewage well 4, and the sewage in the sewage well 4 is discharged through the sewage pump 5.

[0021] However, when the residual water is discharged through the drain pipe 2, it is necessary to control the on-off state of the drain pipe 2 to ensure that the drain pipe 2 is in a closed state when the system is operating normally, and it is opened when it needs to be emptied. Therefore, the drain valve 3 is installed in the same straight line to facilitate the operator to open or close the drain valve 3.

[0022] Among them, the gas or liquid discharged from the drain pipe 2 contains harmful gas. In order to avoid overflow, a main cover plate 6 is provided at the wellhead of the sewage well 4. An operation port is opened on the main cover plate 6 at the corresponding position of the drain valve 3. An operation panel 7 is provided in the operation port. The main cover plate 6 is also provided with an inspection port for maintenance personnel to enter. Correspondingly, an inspection panel 8 is provided in the inspection port. Therefore, when closing, opening or replacing the drain valve 3, it is not necessary to enter the drain valve 3. Only the operation panel 7 needs to be opened to operate through the operation port. In addition, the gas alarm installed in the sewage well 4 includes a combustible gas alarm and a hydrogen sulfide concentration alarm, which monitors the concentration of harmful gas and hydrogen sulfide in the drain valve 3 in real time to ensure the safety of the operator during operation.
