Description

Technical Field

[0001] This utility model relates to the field of biogas holder technology, and in particular to a biogas holder for use in environmental protection equipment. Background Technology

[0002] Biogas projects are one of the important means to solve energy demand and environmental pollution problems. In biogas projects, atmospheric pressure membrane gas holders are usually used to store biogas. Compared with traditional large industrial steel gas holders, membrane gas holders are favored for their simple structure, high safety, convenient operation and low investment cost. Although the storage capacity of membrane gas holders is generally only a few thousand cubic meters, this size is particularly suitable for temporary storage of biogas production, so its application is becoming more and more widespread.

[0003] As disclosed in the patent "Counterweight Biogas Stabilizer" with publication number CN220523583U, "The equipment is also equipped with a condensate drain pipe that is connected to the inside of the equipment shell, and the condensate inside the equipment shell is discharged through the condensate drain pipe." However, under low temperature conditions in winter, the low temperature condensate in the membrane gas holder is very prone to freezing. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 This utility model provides a technical solution: a biogas cabinet for environmental protection equipment, including a cabinet body 1, a biogas gas membrane 13 fixedly connected to the middle of the cabinet body 1, a biogas inlet pipe 3 and a biogas outlet pipe 16 symmetrically arranged fixedly connected to the bottom side of the cabinet body 1, a first drain pipe 8 fixedly connected to the bottom of the cabinet body 1, a counterweight plate 14 fixedly connected to the middle of the biogas gas membrane 13, and the counterweight plate 14 and the cabinet body 1 are movably connected by a connecting rod folding mechanism 15. When the biogas pressure entering the cabinet body 1 through the biogas inlet pipe 3 changes, the biogas gas membrane 13 expands or collapses and drives the counterweight plate 14 to rise or fall, so as to maintain the stable pressure of the biogas output through the biogas outlet pipe 16.

[0027] Specifically, as biogas continuously enters the interior of cabinet 1, the level of biogas membrane 13 rises, and the volume of biogas membrane 13 also continuously increases until the designed volume is reached. During this process, the biogas pressure remains constant, the biogas membrane 13 rises and drives the counterweight plate 14 to rise and drives the connecting rod folding mechanism 15 to fold. Similarly, when the amount of biogas entering cabinet 1 decreases, the level of biogas membrane 13 decreases, and the volume of biogas membrane 13 continuously decreases. During this process, the biogas pressure remains constant, the biogas membrane 13 falls and drives the counterweight plate 14 to fall and drives the connecting rod folding mechanism 15 to unfold.

[0028] Specifically, such as Figure 1As shown, a first cavity 101 is formed between the inner and outer walls of the cabinet 1, located below the biogas membrane 13. A water tank 2 and a booster pump 5 are provided on the bottom side of the cabinet 1. A water inlet pipe 4 is fixedly connected to the top side of the water tank 2. A second cavity 201 is formed between the inner and outer walls of the water tank 2. Several heating rods 7 are arranged in the second cavity 201. The water inlet end of the booster pump 5 is fixedly connected to the bottom side of the water tank 2. The water outlet end of the booster pump 5 is fixedly connected to the top side of the first cavity 101 through a first connecting pipe 6. A second connecting pipe 12 is fixedly connected between the first cavity 101 and the water tank 2. A second drain pipe 11 is fixedly connected between the first drain pipe 8 and the water tank 2. A first valve 9 and a second valve 10 are respectively installed on the first drain pipe 8 and the second drain pipe 11. In winter, firstly, the first valve 9 is closed and the second valve 10 is opened. The heating rod 7 is then activated to heat the water in the water tank 2 until the water temperature reaches the required temperature. Once the water temperature is suitable, hot water is injected into the first clamping cavity 101 through the booster pump 5 and the first connecting pipe 6. The hot water circulates within the first clamping cavity and flows back to the water tank 2 through the second connecting pipe 12, forming a closed hot water circulation system to maintain the temperature of the cabinet 1. During this process, the condensate generated flows into the water tank 2 through the second drain pipe 11. This not only avoids the problem of condensate freezing due to low temperature but also achieves the recycling of condensate, improving the overall efficiency and environmental friendliness of the system.

[0029] In other seasons, the first valve 9 is opened and the second valve 10 is closed. The hot water circulation system is not required, and the condensate can be discharged normally through the first drain pipe 8.

[0030] Working principle: In winter, firstly, close the first valve 9 and open the second valve 10. Start the heating rod 7 to heat the water in the water tank 2 until the water temperature reaches the required temperature. When the water temperature is suitable, the hot water is injected into the first clamping cavity 101 through the booster pump 5 and the first connecting pipe 6. The hot water circulates in the first clamping cavity and flows back to the water tank 2 through the second connecting pipe 12, forming a closed hot water circulation system to maintain the temperature of the cabinet 1. During this process, the condensate generated will flow into the water tank 2 through the second drain pipe 11. This not only avoids the problem of condensate freezing due to low temperature, but also realizes the recycling of condensate, improving the overall efficiency and environmental friendliness of the system.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
