(1) Free and energy-saving heat source joint operation function design
The specific linkage function design is: adopting the control principle of prioritizing free energy, maximizing the use of free energy throughout the year, and secondly utilizing energy-saving heat sources, that is, automatically controlling the opening of energy-saving heat source equipment through a specially designed linkage control cabinet, with various heat source devices
All equipment runs automatically without the need for manual startup. (2) The wellhead fan adopts a constant temperature control mode, which is a key energy-saving technology of our company. The wellhead antifreeze fan adopts a multi-stage control mode of water flow, natural negative pressure air supply, and forced air supply, always maintaining a constant temperature of no less than 5 ℃ and no more than 7 ℃ at the wellhead. It neither allows the wellhead temperature to be too low nor too high, meeting the needs of wellhead antifreeze while preventing energy waste caused by excessive temperature. Note: If temperature control at the wellhead is not implemented, the fan and main heat source can only operate at full speed throughout the entire heating season, which will increase energy consumption by 50-100%.
(3) Anti freezing technology for wellhead fan equipment
Equipment anti freezing: In the cold winter, when the outdoor temperature is low and equipment damage is not dealt with in a timely manner, solving the anti freezing problem of wellhead fan equipment has always been a major challenge for many investment and operation companies. In the winter weather of -10 ℃ in Shandong region, our company has resolved over 20 cases of equipment freezing damage. Through repeated experiments and explorations by our company's leaders and technical personnel, a heat exchanger was installed between the end and the main heat source, and antifreeze was circulated between the end and the heat exchanger. Even in the event of equipment damage, the antifreeze would not freeze and cause damage to the equipment. This design has been experimentally certified and can ensure the normal operation of the equipment even in weather conditions of -25 ℃ in Inner Mongolia.
(4) The full utilization of waste heat extraction technology is another core competitiveness of our company, which significantly reduces the operating costs of users. Waste heat extraction can be divided into three types according to the usage location: exhaust fan waste heat extraction, bathing wastewater waste heat extraction, exhaust shaft waste heat extraction, circulation system waste heat extraction, coal slurry drying waste heat extraction, etc; According to different media and waste heat types, water water heat exchange, oil-water heat exchange, wind water heat exchange, and wind air heat exchange are used respectively; The types of heat exchangers include ordinary plate heat exchangers, shell and tube heat exchangers, heat pipe heat exchangers, and rotary heat exchangers. (5) Extraction technology of waste heat from compressed air fan
Our company has implemented a plan to extract and produce domestic hot water from the waste heat of an air compressor in the Beisu Coal Mine of Yankuang Group. The waste heat generated by the air compressor can only be extracted 70-80%, and cannot be fully extracted, resulting in energy waste. Based on the construction experience of Beisu Coal Mine, we have innovated the technology by adopting the mode of internal extraction of compressor waste heat, adding a heat recovery module to ensure the outlet water temperature, extracting 100% of the waste heat, and adding an energy-saving control system to ensure the temperature and usage of domestic bath hot water. At the same time, it can effectively reduce the oil temperature of the compressor itself, improve its working efficiency, and achieve constant temperature outlet water. (6) The design of the linkage function between water source heat pumps, pressure fans for heating, and solar energy systems is one of our company's core competitiveness in terms of the mutual linkage control function of various heat sources. The specific linkage function design is based on the principle of prioritizing free energy, allowing for maximum utilization of free energy throughout the year. The automatic control group operates fully automatically through a specially designed linkage control cabinet, without the need for manual start-up. The specific method is to set up a set of temperature sensors in a separate linkage control cabinet, which detect the temperature of the thermal storage water tank, constant temperature water tank, roof water tank, etc. During the set time period, when the temperature of the water tank detected by the temperature sensor is below 48 ℃, the circulation pump and the main engine are sequentially started through a time relay and a control contactor. Realize fully automatic start heating. When the water tank temperature reaches 50 ℃, the contactor is controlled by a time relay to turn off the main engine and circulation pump in sequence, achieving fully automatic shutdown of the water source heat pump heating function. The water temperature detection time is the short time when the unit starts heating water, and the rest of the time is given to solar energy and pressure fan heating. (7) Free extraction technology for exhaust shaft waste heat
Free heating: We use an air to air heat exchanger to preheat the intake shaft. This type of heat exchanger is designed by our company as a model heat exchanger, which can be combined on-site according to the situation to form a super large air to air heat exchange unit. The heat extraction method is generally selected to extract 60% of the temperature difference. If the distance between the exhaust shaft and the intake shaft is within the design range, this heating method can be used. Under the action of the fan, natural air enters the heat exchange unit and becomes high-temperature air, which is then transported to the intake shaft through the air duct.
(8) Multiple patented small technologies combined with large systems
Years of construction and maintenance experience have led to the integration of a series of small improvements and inventions into an energy-saving system. Fuzzy control constant temperature mixing device solves the technical problem of large water volume constant temperature water supply. Fuzzy control constant temperature water outlet device solves the technical problem of large temperature difference in unstable heat source heating. The wellhead constant temperature control equipment solves the contradiction between wellhead antifreeze and energy waste. The anti freezing alarm and anti freezing cycle linkage of the wellhead fan solve the problem of equipment anti freezing in poor winter conditions. The sensing of heat, temperature, water volume, and water level, as well as the automatic calculation and sorting starting of PLC, have solved the problem of the linkage of multiple energy sources. The complete set of equipment for pressurized reinjection of well water solves the industry problem of well water reinjection. The temperature sensing cycle of the anti freezing probe adopts a mostly activated functional design, which solves the anti freezing problem of intermittent water supply conditions in large systems and multiple simultaneous uses. The industry is the first to use PLC program control, remote monitoring, and fault diagnosis functions.
