Description
技术领域 technical field
本实用新型涉及除湿技术领域，特别涉及一种带有涡流管的除湿装置。 The utility model relates to the technical field of dehumidification, in particular to a dehumidification device with a vortex tube.
背景技术 Background technique
干燥是工农业生产中广泛使用且耗能巨大的加工环节，世界范围内对干燥过程的节能技术开展了大量研究。传统的开式电加热干燥法将干燥室出来的湿度大、温度相对高的空气直接排入大气，浪费了其中大量的显热和潜热，并且开式循环的性能随环境空气状况的变化而变化。热泵干燥系统则通过蒸发器将干燥室出口空气中的热量回收，并可以在稳定工况下运行。目前已广泛地应用于木材干燥、食品加工、蔬菜脱水、陶瓷烘干、皮革干燥、生物制品及化工原料干燥等领域。如图1所示，传统型的热泵干燥系统包括：压缩机1、回热器2、节流阀10、冷却器4、干燥室6、辅助冷却器8以及风机7。 Drying is a widely used and energy-intensive processing link in industrial and agricultural production. A lot of research has been carried out on energy-saving technologies in the drying process worldwide. The traditional open-type electric heating drying method directly discharges the air with high humidity and relatively high temperature from the drying room into the atmosphere, wasting a lot of sensible heat and latent heat, and the performance of the open cycle changes with changes in ambient air conditions . The heat pump drying system recovers the heat in the outlet air of the drying chamber through the evaporator, and can operate under stable conditions. At present, it has been widely used in wood drying, food processing, vegetable dehydration, ceramic drying, leather drying, biological products and chemical raw materials drying and other fields. As shown in FIG. 1 , a traditional heat pump drying system includes: a compressor 1 , a regenerator 2 , a throttle valve 10 , a cooler 4 , a drying chamber 6 , an auxiliary cooler 8 and a fan 7 .
然而，热泵干燥的温度大都集中在40℃～60℃之间，为了能使热泵干燥所适用的干燥物料范围扩大，所以设法提高干燥的温度也是研究的一个热点。目前较常用的方法是通过辅助加热系统，将经过冷凝器加热过的空气进一步提高其温度，这种方法虽然简单有效，但能源消耗显著增加。 However, the heat pump drying temperature is mostly concentrated between 40°C and 60°C. In order to expand the range of dry materials applicable to heat pump drying, trying to increase the drying temperature is also a research hotspot. At present, the more commonly used method is to further increase the temperature of the air heated by the condenser through the auxiliary heating system. Although this method is simple and effective, the energy consumption will increase significantly.
为了解决热泵干燥的升温问题，公告号为CN101504247A的中国专利文献公开了一种空气源高温热泵除湿干燥设备，该专利采用多个翅片蒸发器构成逐级除湿降温系统，采用多个翅片冷凝器构成逐级加热升温系统。该装置相对于一般的燃料加热和电加热等高温干燥方法，可以降低高温干燥的能耗以及运行成本。然而，该加热系统的加热量限制于热泵系统的冷凝温度，无法进一步提升干燥温度。 In order to solve the temperature rise problem of heat pump drying, the Chinese patent document with the notification number CN101504247A discloses an air-source high-temperature heat pump dehumidification and drying equipment. The patent uses multiple fin evaporators to form a step-by-step dehumidification and cooling system. The device constitutes a step-by-step heating system. Compared with general high-temperature drying methods such as fuel heating and electric heating, the device can reduce the energy consumption and operating cost of high-temperature drying. However, the heating capacity of this heating system is limited to the condensation temperature of the heat pump system, which cannot further increase the drying temperature.
涡流管是一种结构非常简单的能量分离装置，它可以将一股高压流体分离成冷热不同的两股流体，在一定的进口压力下，其冷端出口温度可达-50℃，而热端出口温度可达140℃以上。且涡流管的制冷效应的效率介于等熵膨胀和等焓膨胀之间，相对于传统的膨胀机，其结构简单且无运动部件，相对于节流阀，其效率更高。 The vortex tube is a very simple energy separation device. It can separate a high-pressure fluid into two different fluids. Under a certain inlet pressure, the outlet temperature of the cold end can reach -50 ° C, while The outlet temperature can reach above 140°C. Moreover, the efficiency of the refrigeration effect of the vortex tube is between the isentropic expansion and the isenthalpic expansion. Compared with the traditional expander, its structure is simple and has no moving parts. Compared with the throttle valve, its efficiency is higher.
基于涡流管可以同时实现制冷制热的效果，目前也有一些将涡流管应用于除湿系统的装置。如公开号为CN104174261A的中国专利文献公开了一种基于涡流管制冷技术的压缩空气干燥装置，该干燥装置利用涡流管的冷热出口流体实现除湿溶液的冷却和再生。然而，该装置结构较复杂，影响系统可靠性。又如公开号为CN103727606A的中国专利文献公开了一种使用涡流管冷却及再生的转轮除湿系统及其空气处理方法。采用固态吸附原理的转轮除湿机进行，由于其再生耗能量较大，造价也较高，影响经济性。此外，由于该系统送风风机出口压力并不高，涡流管在该系统中的作用并不显著。 Based on the fact that the vortex tube can achieve cooling and heating effects at the same time, there are currently some devices that apply the vortex tube to the dehumidification system. For example, the Chinese patent document with the publication number CN104174261A discloses a compressed air drying device based on vortex tube refrigeration technology. The drying device uses the cold and hot outlet fluid of the vortex tube to realize the cooling and regeneration of the dehumidification solution. However, the structure of the device is relatively complicated, which affects the reliability of the system. Another example is the Chinese patent document whose publication number is CN103727606A, which discloses a rotary dehumidification system using vortex tube cooling and regeneration and an air treatment method thereof. The rotary dehumidifier adopts the principle of solid-state adsorption, because its regeneration consumes a lot of energy and the cost is also high, which affects the economy. In addition, because the outlet pressure of the air supply fan in this system is not high, the role of the vortex tube in this system is not significant.
