[0041] All the above-mentioned temperature gauges, electromagnetic valves, flow gauges, pressure gauges and circulating water pumps are connected with the central processor; the central processor collects various instrument data and controls the operation of various devices and valves.
[0042] The implementation principle of the fermentation tank is as follows:
[0043] 1. A large amount of heat is generated in the process of decomposition of the liquid organic matter in the fermentation tank by microorganisms and in the process of self-reproduction of the microorganisms.
[0044] 2. The heat exchange pipeline 13 flowing with low-temperature water can take away the high-temperature heat in the liquid organic matter fermentation tank, thereby increasing the temperature of the heating water.
[0045] The heating method based on the ladder type fermentation tank suitable for small and concentrated user heating systems is as follows:
[0046] Step 1: build the heating system based on the ladder type fermentation tank suitable for small and concentrated users: including the indoor ladder type fermentation tank in the heat source area equipment and the equipment room;
[0047] Second step: install the relevant equipment, instruments, valves and connecting pipes;
[0048] Third step: under the action of the heating circulating water pump, the heating water in the fermentation tank after heating, in turn through the heat exchange pipeline 13 and the heating pipeline 16, into the heat preservation hot water tank; the heating water in the heat preservation hot water tank in turn after the heating area, back to the fermentation tank for heating, so as to complete the cycle. Among them, the part of the hot water stored in the heat preservation hot water tank under the action of the auxiliary heating circulating water pump, through the heating of the solar collector, back to the heat preservation hot water tank. The water level in the heat preservation hot water tank exists in the range of small fluctuations.
[0049] The third step is the heating water circulation operation stage.
[0050] Fourth step: when running completely, 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 the 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 the cargo loading platform 102, so as to maintain the efficient heat production of the fermentation tank.
[0051] In the diagram, the 1st, 2nd, 3rd and 4th fermentation tanks are filled with liquid organic fermentation material (there is a certain time interval when filling the liquid organic fermentation material in each fermentation tank, and the 4th fermentation tank starts first, and the 1st fermentation tank starts last). When replacing the liquid organic material: first, open the movable baffle of the 4th fermentation tank, and transfer the waste in the 4th fermentation tank to the 5th cleaning pool, and then transport it away through the cleaning platform; then, open the movable baffle of the 3rd fermentation tank, and transfer the waste in the 3rd fermentation tank to the 4th fermentation tank for continuous fermentation; then, open the movable baffle of the 2nd fermentation tank, and transfer the waste in the 2nd fermentation tank to the 3rd fermentation tank for continuous fermentation; then, open the movable baffle of the 1st fermentation tank, and transfer the waste in the 1st fermentation tank to the 2nd fermentation tank for continuous fermentation; finally, fill the 1st fermentation tank with liquid organic material and microorganisms through the cargo loading platform, so as to maintain the efficient heat production of the fermentation tank.
[0052] The control strategy of the central processor is as follows:

[0055] 1.2, check the values of the first pressure gauge Y1, the second pressure gauge Y2, and the third pressure gauge Y3. If the value of the first pressure gauge Y1 decreases significantly, it indicates that the heating circulating equipment has a large amount of water leakage; if the value of the second pressure gauge Y2 decreases significantly, it indicates that the terminal heating equipment has a large amount of water leakage; if the value of the third pressure gauge Y3 decreases significantly, it indicates that the heat source area equipment has a large amount of water leakage.
[0056] (2) When the water level monitor detects an abnormal rise in the water level in the heat preservation hot water tank, the signal is fed back to the central processor, which processes as follows:
[0057] 2.1, check the values of the first flow gauge L1, the second flow gauge L2, and the third flow gauge L3. If the value of the first flow gauge L1 decreases significantly, it indicates that the heating circulating equipment has a pipe blockage; if the value of the second flow gauge L2 decreases significantly, it indicates that the terminal heating equipment has a pipe blockage; if the value of the third flow gauge L3 decreases significantly, it indicates that the heat source area equipment has a pipe blockage;
[0058] 2.2, close the first solenoid valve F1, the second solenoid valve F2, the third solenoid valve F3, the fourth solenoid valve F4, the eighth solenoid valve F8, the ninth solenoid valve F9, close the heating circulating water pump and the auxiliary heating circulating water pump.
[0059] (3) When the water temperature monitor detects that the water temperature in the heat preservation hot water tank is lower than 38℃, the signal is fed back to the central processor, which processes as follows:
[0060] 3.1, open the fifth solenoid valve F5 and the sixth solenoid valve F6, and run the auxiliary heating circulating water pump;
[0061] 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℃, issue a reminder to check the corresponding fermentation tank in time and update the liquid organic fermentation material in time;
[0062] 3.2, check the values of the fifth thermometer W5 and the sixth thermometer W6. If the value of the fifth thermometer W5 is higher than the value of the sixth thermometer W6, close the fifth solenoid valve F5 and the sixth solenoid valve F6, and stop running the auxiliary heating circulating water pump.
[0063] (4) When the water temperature monitor monitors that the water temperature in the heat preservation hot water tank is higher than 62 DEG C, the signal is fed back to the central processing unit, and the central processing unit processes as follows:
[0064] 4.1, open the seventh electromagnetic valve F7, so that the low temperature return water mixes with the high temperature supply water.
[0065] 4.2, if the water temperature in the heat preservation hot water tank is lower than 60 DEG C, close the seventh electromagnetic valve F7.
[0066] The preferred embodiments described above are only the preferred embodiments of the present application, and it should be pointed out that for those skilled in the art, without departing from the overall concept of the present application, some changes and improvements can be made, which should also be considered as the protection range of the present application.
