If the marsh gas generated by the project is mainly used for generating electricity by a marsh gas generator, heat sources are derived from two places of waste heat of cooling water of a boiler and the generator.
Heating system need set up expansion tank, and its effect is mainly the water expansion volume of holding system, theory of operation: due to the expansion and contraction of the water of the heating system, when the temperature of hot water rises, the volume of the water in the system increases, and when the expansion amount of the water is not contained, the water pressure in the heating system increases, which affects the normal operation; after the expansion tank accommodates the water expansion amount of the system, the water pressure fluctuation of the system caused by the expansion of water can be reduced, the safety and the reliability of the operation of the system are improved, and when the system leaks water or cools down due to some reason, the water level of the expansion tank is reduced to supplement water for the system. In addition, the expansion tank can also play a role in stabilizing the pressure of the system and removing air released by water in the heating process.
The waste heat of the biogas generator is generated along with the operation of the generator, the heat demand time of the fermentation system is related to the feeding operation of fermentation raw materials and the heat dissipation of the system, and the time difference exists between the heat supply and the heat demand, so that a hot water storage tank is required to be arranged to store the hot water generated by the waste heat of the generator so as to be used when the fermentation system needs to be supplied.
For the above reasons, the existing heating systems are all shown in fig. 2, and the expansion tank is separately provided from the hot water storage tank. Tap water in the field area is supplied to the water tank through the soft water treatment system, the liquid level of the water tank is controlled by a floating ball valve in the water tank, and the water supply and the hot water return water are combined and then connected into the boiler, so that the water supplementing requirement of the whole system is met. The boiler hot water and the generator hot water are respectively connected to the hot water storage tank and are cached by the hot water storage tank and then are supplied to the heat supply system for use. The boiler pressure relief pipe is connected to the water tank; the hot water storage tank is provided with a liquid level sensor for detecting the liquid level of the storage tank.
This mode of providing the expansion tank separately from the hot water storage tank has the following disadvantages:

The hot water storage tank needs to be provided with a foundation.
3. Increase control system cost: the water tank and the hot water storage tank are respectively provided with a control system.
4. Increase the operation and maintenance cost: the two systems are respectively provided with valves, pipeline fittings, controls and the like, and fault points are increased.
5. The original hot water storage tank does not control the liquid level, only detects the liquid level, and can not achieve accurate control.

The bottom of the hot water storage tank is provided with a water inlet pipeline 1 which is connected with a water supply system of a field area; the hot water storage tank is connected with the boiler heating device through a first water supply pipeline 4 and a first water return pipeline 5, and is connected with the generator heating device through a second water supply pipeline 7 and a second water return pipeline 8. The hot water storage tank is provided with water outlets at the bottom to the first and second return pipes 5 and 8 and water inlets at the upper to the first and second water supply pipes 4 and 7. The upper part of the hot water storage tank is provided with a water outlet communicated with the heating system, and the lower part of the hot water storage tank is provided with a water inlet communicated with the heating system. And each pipeline is provided with a water pump according to the requirement so as to finish the water pumping and water feeding operation.
The hot water storage tank is also provided with a liquid level sensor 6, an electromagnetic valve 2 is arranged on the water inlet pipeline, and the liquid level sensor and the electromagnetic valve are in linkage control to automatically replenish water for the hot water storage tank.
The top of the boiler heating device is provided with a pressure relief pipe 3 which is increased and communicated with the atmosphere, the height of the pressure relief pipe 3 is not lower than that of the highest liquid level of the hot water storage tank, and the top is bent to avoid falling foreign matters.
In addition, a water softener and a salt box are arranged on the water inlet pipeline. The salt box is filled with resin and salt for adsorbing and replacing calcium ions and magnesium ions in water.
The automatic control system comprises a control host, wherein the control host is respectively communicated and/or electrically connected with a boiler heat supply device, a hot water storage tank and a generator heat supply device, and a preset control program is arranged in the host to control the opening and closing of each pipeline valve and the opening and closing of a pump.
The working principle is as follows:
tap water of a water supply system in a field area is softened by a water softener on a pipeline to remove calcium ions and magnesium ions in the water, and then enters a hot water storage tank from the bottom of the hot water storage tank through the control of an electromagnetic valve on a water inlet pipeline.
The water in the hot water storage tank enters the boiler heating device from the bottom through the first water return pipeline 5, the boiler heating device heats water through burning fuel, and the heated water flows back to the upper part of the hot water storage tank through the first water supply pipeline 4.
Water in the hot water storage tank enters the generator heating device from the bottom through a second water return pipeline 8 to serve as cooling water, and circulating cooling water absorbing waste heat of the generator flows back to the upper portion of the hot water storage tank through a second water supply pipeline 7.
Because the hot water storage tank is higher, the hot water is above, and the cold water is below, has the temperature difference, and upper and lower can not mix to a temperature. So that the upper layer hot water can be sent into the heating system through the pipeline positioned at the upper part of the hot water storage tank to provide heat for the heating system. The water after the heat absorption returns to the lower part of the hot water storage tank through a pipeline.
A control program arranged in the automatic control system presets a lowest water level value and a highest water level value of the hot water storage tank, when the water level detected by a liquid level sensor in the hot water storage tank is lower than the lowest water level value, the program automatically sends a control signal to an electromagnetic valve, and the electromagnetic valve is opened to supplement softened tap water; when the water level detected by the liquid level sensor reaches the highest water level value, the program automatically sends a control signal to the electromagnetic valve to close water inlet.
The system simplifies equipment, the hot water storage tank has two functions of water storage and water supplement, and the production and operation cost is reduced.
The inventive concept is explained in detail herein using specific examples, and the above description of the embodiments is only used to help understand the core idea of the present invention. It should be understood that any obvious modifications, equivalents and other improvements made by those skilled in the art without departing from the spirit of the present invention are intended to be included within the scope of the present invention.
