Description

Technical Field

[0001] The utility model relates to the field of kitchen waste anaerobic fermentation equipment, and more specifically to a stirring shaft seal cleaning device for a horizontal anaerobic digestion tank with an automatic detection function. Background Art

[0002] Horizontal dry anaerobic digestion technology uses a horizontal anaerobic fermentation tank, equipped with one or more driving stirring units. The stirring shaft is driven by a motor in the unit to rotate, and the stirring blades on the stirring shaft rotate accordingly, which plays a role in avoiding stratification of materials in the tank, enhancing the inoculation effect, and assisting in the release of biogas. The stirring shaft of the horizontal digester is designed to be located at the center line of the tank, and below the normal production and operation material level, the stirring shaft is immersed in the fermented sludge in the digester. The horizontal anaerobic digester is a continuous production mode, which is in a state of continuous feeding of kitchen waste and anaerobic biogas production throughout the year. The tank stirring is maintained continuously with the tank production, and forced stirring is applied to the fermented sludge in the tank. In order to ensure the stable and continuous operation of the stirring shaft, the stirring shaft is generally designed and installed in the form of a packing labyrinth seal from the tank wall to the shaft surface. The packing is pressed against the surface of the shaft through the packing gland to form countless labyrinths. When the fermented sludge in the tank passes through the shaft surface, the fermented sludge is throttled many times, which has a sealing effect. Since kitchen waste contains impurities such as sand, gravel, and glass, the impurity particles can wear the sealing packing during the continuous rotation of the agitator shaft. When the wear reaches a certain degree, the sealing effect of the packing decreases, and the sludge in the tank leaks out from the seal, which has a negative impact on production safety and the environment.

[0003] During the installation of the agitator shaft of the digester, in order to facilitate the subsequent maintenance and replacement of the agitator shaft bearings, sealing packings, and rotation in place signals, the agitator shaft unit on the side wall of the tank body adopts an open design. During the production operation, it is generally arranged for manual inspections of the agitator shaft operation. When the shaft seal is found to be leaking, a certain amount of leakage has often accumulated. The leaked fermented sludge will not only bring serious odor to the surrounding environment, but the leakage will not be cleaned up in time, which may cause further wear on the packing seal, resulting in increased wear and more serious leakage, resulting in a vicious cycle. Therefore, in order to timely maintain the leakage of the agitator shaft seal, and to control the negative impact of the leakage on the environment, how to take effective measures to detect the leakage in time, and orderly control the odor generated by the leakage, to ensure the orderly operation of the agitator shaft production, has become a major problem in the operation and management of horizontal dry anaerobic digesters.

[0004] At present, the agitator shaft seal of the horizontal dry anaerobic fermentation tank for food waste is directly exposed to the environment. If the seal packing is worn, the fermented sludge in the tank will leak directly from the packing seal to the outside environment. The shaft seal leakage is inspected manually regularly, and there is no automatic leakage detection device installed. When the fermented sludge leaks out from the shaft seal, there is no leakage receiving pan or receiving hopper installed, and the fermented sludge and the odor it produces cannot be controlled and managed.

[0005] The sludge in the kitchen waste anaerobic fermentation tank is the fermentation residue left after the kitchen waste undergoes anaerobic fermentation to produce biogas. On the one hand, it contains hard impurities such as fine gravel and shells that are fed into the fermentation tank with the kitchen waste, and on the other hand, it contains malodorous gases such as ammonia, hydrogen sulfide, and volatile organic acids. After long-term wear, the fermented sludge may leak from the agitator shaft seal to the external environment. If the sludge is not discovered and cleaned in time, it will have an adverse effect on the agitator shaft seal and the external environment. First, the fine hard impurities contained in the fermentation sludge will accumulate in the agitator shaft seal. As the agitator shaft rotates, the hard impurities will further wear the sealing packing, expand the sealing gap, and reduce the effect of the labyrinth seal, which will not only affect the service life of the sealing packing, but also cause more serious sludge leakage. Secondly, since the agitator shaft unit is directly exposed to the environment, the fermentation sludge leaked from the shaft seal will flow directly along the side wall of the fermentation tank to the ground, thereby causing greater environmental and odor pollution to the embedded parts of the agitator shaft, the tank wall and the surrounding environment of the ground. If it is not cleaned in time, the fermentation sludge will dry and harden, making it more difficult to clean manually. Utility Model Content

In the present utility model, the cleaning and atomizing deodorizing integrated machine 6 includes a cleaning water pump, a cleaning water tank, an atomizing deodorizing pump, a deodorizing agent box, and a control module (not shown in the figure). The control module is connected to and controls the start and stop actions of the gas analysis unit, the cleaning unit, the atomizing deodorizing unit, and the sewage discharge unit.

[0034] The working principle of the present invention is described below through an embodiment:

[0035] A self-check is required before putting it into operation. Start the three-in-one gas analyzer 22, automatically draw air, and clean the odor detection pipeline 21 and related probes; start the cleaning and atomizing deodorizing machine 6 for a power-on self-check to confirm whether the connecting pipelines are connected normally, whether the odor detection pipeline solenoid valve 23, the atomizing deodorizing pipeline solenoid valve 43, the cleaning pipeline solenoid valve 33 and the drain valve 52 are in a closed state, and confirm the connection status of the three-in-one gas analyzer 22 and the odor detection pipeline 21 and the cleaning and atomizing deodorizing machine 6. After all connections are confirmed, the equipment can be put into operation.

[0036] Manually set the automatic detection frequency of the cleaning and atomization deodorization integrated machine 6 according to needs. For example, in the early stage of project construction or after replacing a new set of shaft seals, the overall working condition of the agitator shaft seal is relatively good, and the detection frequency can be set to run once every 3 to 5 days. Then, with the long-term operation of the digester, the wear of the agitator shaft seal gradually increases, and the detection frequency can be gradually increased to once every 0.5 to 1.0 days; set the control limits for ammonia, hydrogen sulfide and combustible gas concentrations; set the cleaning time and atomization deodorization time, and enter the automatic operation state after the settings are completed.

[0037] During the automatic operation, the control module of the cleaning and atomizing deodorizing machine 6 controls the solenoid valve 23 of the odor detection pipeline to open, and the three-in-one gas analyzer 23 analyzes the concentration of ammonia, hydrogen sulfide and combustible gas extracted from the sealing cover 1 by the odor detection pipeline 22, and transmits the detection result data to the control module of the cleaning and atomizing deodorizing machine 6. The control module controls the solenoid valve 23 of the odor detection pipeline to close. If the ammonia or hydrogen sulfide exceeds the set limit, it is judged that the fermented sludge in the digester has leaked from the shaft seal of the stirring shaft, and the next cleaning and deodorizing process is carried out. If it does not exceed the limit, the device will enter the hot standby state and wait for the next frequency detection operation. After entering the cleaning and deodorization process, the control module of the cleaning and atomizing deodorization machine 6 controls to open the cleaning pipeline solenoid valve 33 and the sewage valve 52, and the built-in cleaning water pump of the cleaning and atomizing deodorization machine 6 pumps the water in the cleaning water tank through the cleaning pipeline 31 to the cleaning nozzle 32, and the cleaning nozzle 32 sprays the shaft seal leakage mud, and the washed mud will be discharged to the sewage pipe along the sewage pipe 51. After the cleaning is completed, the control module of the cleaning and atomizing deodorization machine 6 controls to close the cleaning pipeline solenoid valve 33 and the sewage valve 52 to prevent the sewage pipe odor from escaping into the sealing cover 11 along the sewage pipe 51. Finally, entering the atomizing deodorization process, the control module of the cleaning and atomizing deodorization machine 6 controls to open the atomizing deodorization solenoid valve 43, and the atomizing deodorization pump of the cleaning and atomizing deodorization machine 6 pumps the deodorizing agent in the deodorizing agent box through the atomizing deodorization pipeline 41 to the atomizing deodorizing nozzle 42, and sprays to remove the odor substances in the sealing cover 11. After the spraying is completed, the control module of the cleaning and atomizing deodorizing integrated machine 6 controls to close the atomizing deodorizing pipeline electromagnetic valve 43, thereby completing the automatic detection, cleaning and deodorizing process.

[0038] The cleaning and atomizing deodorizing machine 6 can set abnormal alarm functions according to manual needs. For example, the control module of the cleaning and atomizing deodorizing machine 6 can be set to receive the detection data transmitted by the three-in-one gas analyzer 22 twice in a row and judge that the odor concentration is high or judge that the agitator shaft seal is leaking mud according to the data twice in a row, then a shaft seal maintenance alarm will be issued to prompt the agitator shaft maintenance personnel to check the shaft seal wear and maintain the shaft seal in time to avoid further expansion of the mud leakage problem. In addition, in order to improve the production safety of the agitator shaft area, the three-in-one gas analyzer 22 detects the concentration of combustible gas. If a high concentration of combustible gas is detected during the odor detection process, the control module of the cleaning and atomizing deodorizing machine 6 will control the sound and light alarm device to alarm after receiving the detection result data, so that the factory management personnel can find and check the production safety hazards in the area in time.

[0039] The cleaning and atomizing deodorizing integrated machine 6 is also provided with a switch for switching between automatic and manual functions, which can be switched to the manual function to manually start the entire process or phased process of detection, cleaning and deodorizing, thereby improving the flexibility of the device.

[0040] Compared with the prior art, the utility model has the following advantages:

[0041] (1) The complete set of equipment is equipped with gas analysis unit, atomization deodorization unit, cleaning unit, sewage discharge unit, control module and other units, which can realize automatic detection and cleaning of mud leakage problems in the shaft seal of the horizontal anaerobic digester, saving the labor cost of regular inspection and cleaning of mud leakage;

[0042] (2) The device uses a sealing cover, frame sealing gasket and elastic sealing ring to effectively control the odor impact of fermented sludge leakage from the shaft seal on the external environment, control the odor within the sealing cover, and further control the odor problem through atomization deodorization. The control module combines the cleaning process with the sewage valve, and the cleaning sewage of the fermented sludge can be directly discharged into the sewage pipe without escaping along the tank wall to the surrounding environment;

[0043] (3) The control module in the cleaning and atomizing deodorizing machine has an alarm function. If the shaft seal leaks mud frequently, it can send an abnormal shaft seal warning to the maintenance personnel according to the setting, so as to facilitate timely maintenance of the shaft seal assembly and avoid further expansion of the mud leakage problem;

[0044] (4) The control module of the cleaning and atomizing deodorizing machine is combined with a three-in-one gas analyzer to automatically or manually detect flammable, explosive, toxic and harmful gases in the stirring shaft area. When the detection value exceeds the set upper limit, an (audible and visual) alarm will be issued to ensure the safety of production in the area.

[0045] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
