Supply air energy wood drying equipment |Wood drying equipment
Electric drive compressor The heat energy in the compressed air generates 100-120 ℃ heat source and flows in the exchanger. The supporting axial flow high-temperature and humidity resistant circulating fan in the drying room absorbs the heat in the exchanger and generates 70-90 ℃ hot air into the drying room. The circulating hot air evaporates the water in the wood through the wood stack and returns to the exchanger for exchange heating. After continuous circulation, Not only can the temperature in the drying room be gradually increased, but also the wood can be continuously evaporated; After pre heating, heating and steaming, the wood drying process control system independently developed by our company will automatically carry out moisture removal treatment according to the set process parameters; The system will also set the wood drying process such as intermediate humidity adjustment treatment, final balance treatment and cooling treatment according to different wood drying processes, which can achieve the drying quality and drying time of conventional drying by combining air energy and new energy other heat pump The advantages that drying manufacturers can't match (the condensation dehumidification mode designed by general heat pump drying manufacturers will extend the drying time of wood, which is one third more than the conventional drying time). The dryer uses 1KW electric energy to drive the compressor to collect heat in the air and generate heat energy of more than 2.2-3.8KW (the energy efficiency ratio is between 2.2-3.8 according to the ambient temperature). The operation cost is 30-50% less than that of electric heating and other heat sources. Environmental protection, safety, energy conservation and automation of equipment operation; It works automatically according to the parameters set by the control system, the hot air dynamic circulation in the drying room, and the relative humidity can be flexibly controlled, which is conducive to the technical treatment in the wood drying process, so that the moisture in the wood can be reasonably and quickly evaporated. It can achieve drying effect and save energy consumption. It is an energy-saving and environment-friendly drying equipment for wood drying at present (in the actual case, the drying cost of 58 yuan/m ³ and the drying time of 80 hours for drying 5cm thick southwest birch wood from the moisture content of 18% to 8%).
Equipment composition:
Energy saving and environmental protection air energy heat source wood drying equipment consists of air energy heat pump, heat preservation water tank, circulating water supply system, aluminum alloy kiln body, kiln door (lifting door device), heating system, humidity control system, air circulation system, air inlet and exhaust system, electrical auxiliary system, detection system and control system.
Equipment principle ：
The heat source of energy-saving and environment-friendly air energy wood drying equipment is high-temperature hot water air energy heat pump and stainless steel heat preservation water tank. The heat pump host configured to compress and collect the heat in the air can generate 80-85 ℃ high temperature hot water, and the energy saving efficiency can reach 2.78 (the heat in the compressed air of 1KW electric energy can generate 2.78 times the heating capacity of about 2400 kcal); The supporting stainless steel insulated water tank stores the hot water generated by the host. The circulating water pump transfers the high-temperature hot water in the insulated water tank to the hot water exchanger in the drying kiln. The airflow circulation system (fan) in the kiln exchanges the hot water heat in the hot water exchanger to the air to heat the air. The heated hot air evenly passes through the sawn timber stack to heat the sawn timber, The moisture content in the sawn timber is absorbed into the hot air to form humid and hot air, and the moisture (moisture) in the humid and hot air is discharged by the air inlet and exhaust system to achieve the wood drying effect.
effect:
The hot water after heat exchange of the heat exchanger returns to the insulation water tank, and then the air energy heat pump continues to heat the recovered hot water. The heat is reused, which can save 22-33% energy consumption for the whole wood drying process. Air energy heat pump is an energy-saving and environmental protection product advocated by the state, free of any waste gas and pollution. It is a new heat source configuration required for wood drying temperature below 75 ℃. It is especially suitable for areas with an average climate temperature of 20 ℃ or above. It is also suitable for areas with high environmental requirements and customers who pay attention to energy conservation requirements. It can be used in the fields of secondary wood drying and mahogany drying in furniture factories, with obvious energy-saving effect, convenient and safe use. The air energy heat pump heat source sawn timber drying equipment is equipped with a fully automatic control system, which is safe and reliable in operation. The process flow is stored in the host, and the whole kiln drying process is intelligently controlled, improving and ensuring the drying quality.
Technical field of accessories:
The environmental protection and energy saving air energy wood drying equipment has energy saving, environmental protection, automatic operation of air energy heat pump high temperature hot water heat source, and automatic control of wood drying process. Energy saving and environmental friendly wood drying equipment that can ensure that drying wood will not cause emission pollution to the environment, save labor, and improve drying quality.
Wood drying is an indispensable process in wood deep processing. Now many furniture manufacturers
The industry, wood products and mahogany furniture factories are equipped with wood drying equipment to dry wood and stabilize product quality.
Most of the existing wood drying equipment uses steam boilers, hot water heaters or hot air stoves that burn wood or coal as energy sources to generate heat. The equipment not only pollutes the environment, but also consumes large energy. The operation is complex, the safety factor is low, and it is easy to cause fires; High labor cost and low economic benefit. The equipment has high maintenance rate, short service life and other defects.
