蒸汽喷射式热泵木材干燥供热系统

在木材加工企业,木材干燥所消耗的热量占整个企业总能耗的70%左右.因此在木材干燥过程中进行节能,其意义十分重大.将蒸汽喷射式热泵技术应用于木材干燥,可以降低木材干燥的能耗,提高干燥质量和经济效益;蒸汽喷射式热泵以水蒸汽为工质,冷凝温度可以较高,适用于各种木材在不同的温度下的干燥以及高温干燥.它兼有蒸汽干燥适应性广和除湿干燥节能的优点,避免了除湿干燥不能喷蒸、干燥温度低的缺点.

Heating system in wood drying with steam-jet heat pump

Since the consumption of heat energy in the wood drying process accounts for 60%-70% in wood manufacture, energy saving is very important during the wood drying. The author introduces a steam-jet heating pump into wood drying, which can reduce the energy consumption and improve the quality of wood drying. In the steam-jet heat pump, steam and water are the working substances, so condensing temperature could be higher than the refrigerant normally used in heat pump. It is suitable for wood drying of all kinds of species at different temperatures, especially in high-temperature drying. It possesses the merits of steam kiln drying and dehumidification drying,and avoids the disadvantages of no steaming and low temperature in dehumidification drying.
