[0042] The working condition of the heating system suitable for small cluster users based on the ladder type fermentation tank is as follows:

[0043] First step: build a suitable small user heating system based on the ladder fermentation tank: including indoor ladder fermentation tank in equipment 1 in heat source area and equipment room;

[0044] Second step: install related equipment, instruments, valves and connecting pipelines;

[0045] Third step: under the action of heating circulating water pump 23, the heating water after the fermentation tank is heated, passes through heat exchange pipeline 13 and heating pipeline 16 in turn, and enters heat preservation hot water tank 24; the heating water in heat preservation hot water tank 24 passes through the heating area in turn and then returns to the fermentation tank for heating, so as to complete the circulation. Part of the hot water stored in heat preservation hot water tank 24 is returned to heat preservation hot water tank 24 under the action of auxiliary heating circulating water pump 28 after being heated by solar energy collector 26. The water level in heat preservation hot water tank 24 fluctuates within a small range.

[0046] The third step is the heating water circulation operation stage.

[0047] Fourth step: when completely running, each fermentation tank is filled with liquid organic fermentation material, the fermentation tank on the lowest step starts fermentation first, and the fermentation tank on the highest step ferments last; when replacing the liquid organic material: first, open the movable baffle of the fermentation tank on the lowest step, and transfer the waste in the fermentation tank on the lowest step to cleaning platform 101 and then transport it away; then, open the movable baffles of the fermentation tanks on the lowest step in turn, and transfer the waste in the fermentation tanks on the higher steps to the fermentation tanks on the lowest step in turn; finally, fill the fermentation tank on the highest step with liquid organic material and microorganisms through goods loading steps 102, so as to maintain the efficient heat production of the fermentation tank.

[0052] 1.2, check the values of the first pressure gauge Y1, the second pressure gauge Y2, and the third pressure gauge Y3.

[0054] 2.1, check the values of the first flow meter L1, the second flow meter L2, and the third flow meter L3. If the value of the first flow meter L1 is greatly reduced, it indicates that the heating circulating device 2 has a pipe blockage; if the value of the second flow meter L2 is greatly reduced, it indicates that the terminal heating device 3 has a pipe blockage; if the value of the third flow meter L3 is greatly reduced, it indicates that the heat source area device 1 has a pipe blockage;

[0055] 2.2, close the first electromagnetic valve F1, the second electromagnetic valve F2, the third electromagnetic valve F3, the fourth electromagnetic valve F4, the eighth electromagnetic valve F8, and the ninth electromagnetic valve F9, and close the heating circulating water pump 23 and the auxiliary heating circulating water pump 28.

[0056] (3) When the water temperature monitor detects that the water temperature in the heat preservation hot water tank 24 is lower than 38℃, the signal is fed back to the central processor 27, and the central processor processes as follows:

[0057] 3.1, open the fifth electromagnetic valve F5 and the sixth electromagnetic valve F6, and run the auxiliary heating circulating water pump 28;

[0058] 3.2, check the values of the first thermometer W1, the second thermometer W2, the third thermometer W3, and the fourth thermometer W4. If the value of a certain thermometer is lower than 38℃, an alarm is issued to check the corresponding fermentation tank in time and update the liquid organic fermentation material in time;

[0059] 3.2, check the value of the fifth temperature meter W5 and the sixth temperature meter W6. If the value of the fifth temperature meter W5 is higher than the value of the sixth temperature meter W6, then close the fifth electromagnetic valve F5 and the sixth electromagnetic valve F6, and stop running the auxiliary heating circulating water pump 28.

[0060] (4) When the water temperature monitor monitors that the water temperature in the heat preservation hot water tank 24 is higher than 62℃, the signal is fed back to the central processor 27, and the central processor processes as follows:
