DETAILED DESCRIPTION

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example 1

[0031] A preferred embodiment of a heat storage high-temperature baffled anaerobic fermentation device provided by the utility model is as follows Figures 1 to 10 As shown: a heat storage high-temperature baffled anaerobic fermentation device, including an installation chamber 1, and a fermentation mechanism 2 is installed inside the installation chamber 1.

[0032] The fermentation mechanism 2 includes an auxiliary component 21 and a transmission component 22, and the fermentation mechanism 2 can help the wastewater to be fully fermented.

[0033] In this embodiment, the auxiliary component 21 includes a partition 211, a low-temperature heat exchange baffle hydrolysis zone 212, a nanobubble aerobic digestion zone 213, a medium-temperature heat exchange baffle acidification zone 214, a sub-high-temperature heat exchange baffle acidification zone 215, a high-temperature heat exchange baffle fermentation zone 216, an ultra-high temperature disinfection zone 217 and a high-temperature baffle fermentation zone 218.

[0034] In this embodiment, the partition 211 is fixedly connected to the inner wall of the installation chamber 1, and a low-temperature heat exchange baffle hydrolysis zone 212 is arranged on one side of the partition 211, and a nanobubble aerobic digestion zone 213 is arranged on the side of the low-temperature heat exchange baffle hydrolysis zone 212, and a medium-temperature heat exchange baffle acidification zone 214 is arranged on one side of the nanobubble aerobic digestion zone 213. A high-temperature heat exchange baffle fermentation zone 218 located inside the installation chamber 1 is arranged at one end of the medium-temperature heat exchange baffle acidification zone 214, and a sub-high-temperature heat exchange baffle acidification zone 215 located inside the installation chamber 1 is arranged at one end of the high-temperature baffle fermentation zone 218, a high-temperature heat exchange baffle fermentation zone 216 is arranged on one side of the sub-high-temperature heat exchange baffle acidification zone 215, and an ultra-high-temperature disinfection zone 217 is arranged on one side of the high-temperature heat exchange baffle fermentation zone 216.

[0035] In this embodiment, the partition plate 211 has the dual functions of heat exchange and deflection, which can increase the temperature of the wastewater in sequence after multiple heat exchanges, and can make each chamber correspond to a different temperature.

[0036] In this embodiment, the transmission component 22 includes a first water inlet connecting pipe 221, a second water inlet connecting pipe 222, a water outlet connecting pipe 223, a water inlet pipe 224 and a water outlet pipe 225. By setting the transmission component 22, the transmission of wastewater inside the equipment can be controlled.

[0037] In this embodiment, the first water inlet connecting pipe 221 is fixedly connected to the interior of the installation chamber 1, and a second water inlet connecting pipe 222 located inside the installation chamber 1 is provided on one side of the first water inlet connecting pipe 221, and a water outlet connecting pipe 223 located inside the installation chamber 1 is provided below the first water inlet connecting pipe 221 and the second water inlet connecting pipe 222, a water outlet connecting pipe 225 fixedly connected to the water outlet connecting pipe 223 is fixedly connected to the left side of the installation chamber 1, and a water inlet pipe 224 communicating with the first water inlet connecting pipe 221 is fixedly connected to the back side of the installation chamber 1.

[0038] In this embodiment, the first water inlet connecting pipe 221, the second water inlet connecting pipe 222 and the water outlet connecting pipe 223 are all designed in a "U" shape. The three groups of pipes in the "U" shape can prolong the residence time of wastewater in the corresponding chamber, thereby reacting more thoroughly.

[0039] Example 2

[0040] Based on Example 1, a preferred embodiment of a heat storage high-temperature baffled anaerobic fermentation device provided by the utility model is as follows Figures 1 to 10As shown: a guide plate 3 fixedly connected to the installation chamber 1 is arranged below the water inlet pipe 224, and a connecting hole 4 located inside the installation chamber 1 is arranged on one side of the guide plate 3.

[0041] In this embodiment, the drainage plate 3 is designed to be inclined, and the connecting hole 4 is flush with the lowest point of the inclined surface of the drainage plate 3. The wastewater dripping at the water inlet pipe 224 will drip onto the water inlet pipe 224 and flow downward along the inclined surface of the water inlet pipe 224, and finally flow into the interior of the equipment again through the connecting hole 4.

[0042] The working principle and use process of the utility model are as follows: first, 26°C normal temperature organic wastewater enters the low temperature heat exchange baffle hydrolysis zone 212 through the water inlet pipe 224, and enters the medium temperature heat exchange baffle acidification zone 214 through the first water inlet connecting pipe 221. After multiple heat exchanges, the water temperature rises in sequence, and each chamber corresponds to a different temperature. While exchanging heat, floating objects and heavy metals in the wastewater are successively retained in the previous chamber. When the inlet water reaches the optimal fermentation temperature of 52-55 degrees in the high temperature baffle fermentation zone 218 after heat exchange, it enters the high temperature heat exchange baffle fermentation zone 216 for high temperature anaerobic fermentation. After the anaerobic fermentation is completed, the biogas slurry enters the high temperature heat exchanger through the guide pipe.

[0043] When the wastewater is heated to the highest temperature required for sterilization (adjustable from 70 to 90 degrees), it enters the ultra-high temperature disinfection zone 217, and the high-temperature wastewater after heat exchange is heated to 2-3 degrees. When the wastewater is heated to the highest temperature, it is heated again to reduce heating energy consumption, improve the sterilization function, and maintain the thermal balance of the system. Then, the wastewater is refluxed through the outlet connecting pipe 223 to exchange heat for the entire system, and the wastewater is fermented at high temperature and sterilized. Then, it is heat exchanged with the inlet liquid, and the temperature is lowered in turn, and secondary anaerobic fermentation is performed. , making anaerobic fermentation more efficient and thorough. When the temperature drops to the 35-40 degree area, the nano bubble aerobic digestion zone 213 is used to aerobically treat the biogas slurry. Finally, the treated biogas slurry water is discharged through the outlet pipe 225. By setting the drainage plate 3, the drainage plate 3 is in an inclined state. The wastewater dripping at the water inlet pipe 224 will drip on the water inlet pipe 224 and flow downward along the slope of the water inlet pipe 224. Finally, it flows into the equipment again through the connecting hole 4 to prevent the wastewater from dripping on the ground and causing environmental pollution.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
