Abstract
The present invention relates to a production equipment heat recovery and humidity control module and a heat recovery and humidity control system using same. In the heat recovery and humidity control module, an adsorption dehumidification wheel is provided at a fresh air entrance, and an adsorption region of the adsorption dehumidification wheel is used to absorb the water vapor in outdoor fresh air, thus, the moisture in the outdoor fresh air can be removed to a large extent, so as to reduce the impact of air humidity changes caused by seasonal changes on the coating production speed and product quality. No additional regeneration heater is provided for the adsorption dehumidification wheel, and part of the high-temperature gas discharged from a drying oven directly acts on a regeneration region of the adsorption dehumidification wheel to desorb the water vapor adsorbed on the wheel and regenerates the water vapor to external air, thereby further reducing the energy consumption of a system. In addition, in the present invention, a heat exchanger is used to exchange heat between external low-temperature fresh air and the high-temperature gas in production equipment, so that the external low-temperature fresh air can be heated to a temperature close to a drying temperature and introduced into the drying oven. Therefore, there is no need to provide a fresh air heater for the system, thereby greatly reducing the energy consumption of the system.
Description
本发明涉及一种生产设备热回收控湿模块及应用该模块的热回收控湿系统，特别是利用除湿转轮与热交换器相结合实现生产设备节能恒湿调节的模块化处理方案。The invention relates to a heat recovery and humidity control module of production equipment and a heat recovery and humidity control system using the module, in particular to a modular processing scheme for realizing energy-saving and constant humidity adjustment of production equipment by combining a dehumidification wheel and a heat exchanger.
电池阳极极片涂布生产过程中，阳极极片的烘干是关键的工序之一，烘干过程由于需要将外界新风加热到指定烘干温度，需要较高的能耗，图1所示为现有涂布机烘箱100的高能耗解决方案，在该方案中设置有换热器201，该换热器201可将涂布机烘箱100内部的高温废气与外界送入的新风进行热量交换，从而使新风温度尽可能达到指定烘干温度，这种设备构成简单，设备投资成本低，装置自身运行成本较低，且大大降低了将新风加热到烘干温度所需的能耗。In the production process of battery anode electrode sheet coating, the drying of the anode electrode sheet is one of the key processes. The drying process requires high energy consumption due to the need to heat the external fresh air to the specified drying temperature, as shown in Figure 1. The high energy consumption solution of the existing coating machine oven 100, in which a heat exchanger 201 is provided, and the heat exchanger 201 can exchange heat between the high-temperature exhaust gas inside the coating machine oven 100 and the fresh air sent in from the outside, In this way, the fresh air temperature can reach the designated drying temperature as much as possible. This kind of equipment has simple structure, low equipment investment cost, low operating cost of the device itself, and greatly reduces the energy consumption required to heat the fresh air to the drying temperature.
然而该方案同样存在如下缺陷：(1)向烘箱内所送空气是经过热交换器的室外新风，湿度相对较高，无法达到低露点干燥环境要求；(2)送风空气湿度随时间、季节变化较大，容易影响涂布的生产速度及产品质量；(3)为了能够在外气湿度较高的天气(季节)情况下，也能够排除烘箱产生的水分，均需要加大送风风量以及排风风量，这将反过来造成涂布机能耗提高、大大增加了运行成本。However, this scheme also has the following defects: (1) the air sent to the oven is the outdoor fresh air passing through the heat exchanger, and the humidity is relatively high, which cannot meet the requirements of a low dew point dry environment; (2) the humidity of the air supply varies with time and seasons. The change is large, and it is easy to affect the production speed and product quality of the coating; (3) In order to be able to remove the moisture generated by the oven in the weather (season) with high humidity outside the air, it is necessary to increase the air supply and exhaust Air volume, which will in turn cause increased energy consumption of the coating machine, greatly increasing operating costs.

Specifically: when the outdoor fresh air enters the fresh air inlet of the heat recovery and humidity control module 200 with an initial temperature of 36°C, an air volume of 41400m 3 /h, and a humidity of 24.7g/kg, and acts on the adsorption area 2021 of the adsorption dehumidification rotor 200, the fresh air temperature As the temperature rises and the humidity decreases, it will enter the heat exchanger 201 with a temperature of 53.0°C, an air volume of 41400m 3 /h, and a humidity of 20g/kg. After heat exchange with part of the high-temperature gas discharged from the oven, the fresh air temperature and air volume entering the oven and humidity will become 71.6℃, 41400m 3 /h and 20g/kg respectively, and the temperature, air volume and humidity of the high-temperature gas after the oven drying step will be respectively 80℃, air volume 46000m 3 /h, and humidity 32.2g/kg kg; the high-temperature gas discharged from the oven will be divided into two branches, one of which (temperature 80°C, air volume 25300m 3 /h, humidity 32.2g/kg) is introduced into the heat exchanger 201, and is mixed with the low-temperature gas after adsorption and dehumidification.

图4为本发明热回收控湿模块第三实施例中的除湿吸附转轮结构示意图。该优选实施例与第一实施例和第二实施例相比主要改进点在于吸附除湿转轮结构。为了进一步提升吸附除湿效果，可将吸附除湿转轮202的吸附区2021上设置为若干子吸附区，将外界新风依次通过子吸附区以达到逐级梯度除湿效果。如图4所示，所述吸附除湿转轮202的吸附区2021包括两个子吸附区，分别为第一子吸附区20211和第二子吸附区20212，外界低温新风在进入热交换器201之前依次通过第一子吸附区20211和第二子吸附区20212，且所述第一子吸附区20211的面积可优选大于所述第二子吸附区20212的面积，可使处于相对较高浓度状态的来自外界新风中的一部分水气以相对较低 的风速通过第一子吸附区20211，另一方面第二子吸附区20212的面积较小可以提高处于相对较低浓度的水气的流速以增加其与吸附除湿转轮202气体通道之表面的碰撞接触概率，从而达到提高水气吸附净化效率的目的；所述吸附除湿转轮202的吸附材料优选为硅胶、沸石，也可以是氯化锂。Fig. 4 is a schematic structural diagram of the dehumidification and adsorption runner in the third embodiment of the heat recovery and humidity control module of the present invention. Compared with the first embodiment and the second embodiment, the main improvement of this preferred embodiment lies in the structure of the adsorption dehumidification wheel.

On the other hand, the smaller area of the second sub-adsorption area 20212 can increase the flow rate of the water vapor at a relatively low concentration to increase its interaction with the air. The collision contact probability of the surface of the gas channel of the adsorption dehumidification wheel 202 is used to achieve the purpose of improving the efficiency of water vapor adsorption and purification; the adsorption material of the adsorption dehumidification wheel 202 is preferably silica gel, zeolite, or lithium chloride.
具体而言，当室外新风以初始温度36℃、风量41400m
3/h，湿度24.7g/kg进入热回收控湿模块200的新风入口并依次作用于吸附除湿转轮200的第一子吸附区20211和第二子吸附区20212后，新风温度、风量与湿度将依次变为59.0℃、41400m
3/h、15g/kg，由此可见，经过二级吸附后，新风湿度将显著低于具有一个吸附区2021的吸附除湿转轮，进一步提升了吸附除湿效率。
Specifically, when the outdoor fresh air enters the fresh air inlet of the heat recovery and humidity control module 200 with an initial temperature of 36°C, an air volume of 41,400 m 3 /h, and a humidity of 24.7 g/kg, it acts on the first sub-adsorption area 20211 of the adsorption and dehumidification rotor 200 in sequence.
