Description
技术领域technical field
本发明涉及深度除湿技术领域，特别是指节能型锂电池生产环境处理系统。The invention relates to the technical field of deep dehumidification, in particular to an energy-saving lithium battery production environment treatment system.
背景技术Background technique
在工业生产过程中，锂电池生产环境中湿度的控制是一个重要指标。目前比较成熟的除湿技术有冷却式除湿、液体吸收式除湿、固体吸附式除湿、膜法除湿及转轮除湿。除湿转轮是一个载有吸湿剂的蜂窝状的特殊纸质转轮，由于蜂窝状孔径仅1.5mm，故1m3的转轮纸芯吸湿面积达3000m2。空气流经蜂窝状孔道处于边界层流状态，湿交换效果好，所以除湿能力较强。锂电池生产车间需要相对湿度很低的环境工况，目前主要运用二级转轮除湿装置进行处理，再生风温度需要较大，一级二级转轮再生风温度都在100℃以上，常规的转轮除湿再生风加热一般为电加热，由于再生风加热温度很高，这就消耗了很大的能源，运行成本非常高。In the industrial production process, the control of humidity in the lithium battery production environment is an important indicator. At present, the relatively mature dehumidification technologies include cooling dehumidification, liquid absorption dehumidification, solid adsorption dehumidification, membrane dehumidification and rotary dehumidification. The dehumidifying wheel is a honeycomb-shaped special paper wheel loaded with hygroscopic agent. Since the honeycomb-shaped aperture is only 1.5mm, the 1m 3 wheel paper core has a moisture absorption area of 3000m 2 . The air flowing through the honeycomb channels is in the state of boundary laminar flow, and the moisture exchange effect is good, so the dehumidification ability is strong. The lithium battery production workshop requires an environmental condition with low relative humidity. At present, the secondary runner dehumidification device is mainly used for treatment, and the regeneration air temperature needs to be relatively large. Rotary dehumidification regeneration air heating is generally electric heating. Due to the high heating temperature of the regeneration air, it consumes a lot of energy and the operating cost is very high.

本发明中所述的热泵系统工作原理如下：The working principle of the heat pump system described in the present invention is as follows:
制冷循环系统工作原理如下：压缩机压缩后的高温高压气体进入风冷冷凝器Ⅰ冷凝放热后变成高温高压的液体，然后进入储液器，储液器出来的制冷剂分两路，一路经膨胀阀Ⅰ进入风冷蒸发器Ⅰ，吸收来自于处理风的热量辅助初步除湿；另一路经膨胀阀Ⅱ进入风冷蒸发器Ⅱ，吸收来自于一级转轮后风的热量。The working principle of the refrigeration cycle system is as follows: the high-temperature and high-pressure gas compressed by the compressor enters the air-cooled condenser I, condenses and releases heat, and turns into a high-temperature and high-pressure liquid, and then enters the liquid accumulator. The refrigerant from the liquid accumulator is divided into two paths, one path It enters the air-cooled evaporator I through the expansion valve I, and absorbs the heat from the processing wind to assist the preliminary dehumidification; the other enters the air-cooled evaporator II through the expansion valve II, and absorbs the heat from the rear wind of the first-stage runner.
高温热泵系统工作原理如下：经热泵压缩机压缩后的高温高压制冷剂，经过风冷冷凝器Ⅱ冷凝放热后，进入膨胀阀Ⅲ节流形成温度相对较低的低压制冷剂，进入风冷蒸发器Ⅲ吸热，最后进入热泵压缩机入口完成整个循环。风冷蒸发器Ⅲ的进风是来自于制冷系统风冷冷发器Ⅰ的高温热风，从而保证热泵系统具有较高蒸发温度，这样可以使冷凝器最大限度的加热再生风，且同时保证系统具有较高的能效。The working principle of the high-temperature heat pump system is as follows: the high-temperature and high-pressure refrigerant compressed by the heat pump compressor, after condensing and releasing heat through the air-cooled condenser II, enters the expansion valve III for throttling to form a relatively low-temperature low-pressure refrigerant, and enters the air-cooled evaporation. Heater III absorbs heat, and finally enters the inlet of the heat pump compressor to complete the entire cycle. The air inlet of the air-cooled evaporator III is the high-temperature hot air from the air-cooled chiller I of the refrigeration system, so as to ensure that the heat pump system has a high evaporation temperature, so that the condenser can heat the regeneration air to the maximum extent, and at the same time ensure that the system has a high evaporating temperature. Higher energy efficiency.
二级转轮除湿系统包括空气处理循环和再生风循环，所述空气处理循环中，新风和室内风混合以后通过风冷蒸发器Ⅰ降温和辅助除湿，然后进入一级转轮进行除湿，再进入风冷蒸发器Ⅱ降温，然后进入二级转轮进行二级除湿，最后经过电加热器Ⅲ处理到相应的温度。所述再生风循环中，新风与二级转轮出来的再生风通过显热交换器升温后，进入风冷冷凝器Ⅱ进行二次加热，通过电加热器Ⅰ后再进入一级转轮，然后进入电加热器Ⅱ，再进入二级转轮，出来后进入显热交换器，最后排入大气。The two-stage runner dehumidification system includes an air treatment cycle and a regeneration air cycle. In the air treatment cycle, after the fresh air and indoor air are mixed, they pass through the air-cooled evaporator I for cooling and auxiliary dehumidification, and then enter the first-stage runner for dehumidification. The air-cooled evaporator II cools down, then enters the secondary runner for secondary dehumidification, and finally is processed to the corresponding temperature by the electric heater III. In the regenerated air cycle, after the fresh air and the regenerated air from the secondary runner are heated through the sensible heat exchanger, they enter the air-cooled condenser II for secondary heating, pass through the electric heater I and then enter the primary runner, and then enter the air-cooled condenser II for secondary heating. Enter the electric heater II, then enter the secondary runner, enter the sensible heat exchanger after coming out, and finally discharge into the atmosphere.
本发明的有益效果在于：The beneficial effects of the present invention are:
本发明的再生风通过余热回收方式对再生风进行预热，然后利用高温热泵加热，其中高温热泵的低温热源来自于制冷系统的冷凝热，可最大限度的实现再生风温度要求。比电加热直接加热再生风节能2-3倍，效果明显。The regeneration air of the present invention preheats the regeneration air by means of waste heat recovery, and then uses the high temperature heat pump to heat, wherein the low temperature heat source of the high temperature heat pump comes from the condensation heat of the refrigeration system, which can maximize the regeneration air temperature requirement. Compared with the electric heating directly heating the regenerative air, the energy saving is 2-3 times, and the effect is obvious.

本发明中所述的热泵系统工作原理如下：The working principle of the heat pump system described in the present invention is as follows:
制冷循环系统工作原理如下：压缩机1压缩后的高温高压气体进入风冷冷凝器Ⅰ2冷凝放热后变成高温高压的液体，然后进入储液器7，储液器7出来的制冷剂分两路，一路经膨胀阀Ⅰ3进入风冷蒸发器Ⅰ4，吸收来自于处理风的热量辅助初步除湿；另一路经膨胀阀Ⅱ5进入风冷蒸发器Ⅱ6，吸收来自于一级转轮13后风的热量。The working principle of the refrigeration cycle system is as follows: the high-temperature and high-pressure gas compressed by the compressor 1 enters the air-cooled condenser I2 to condense and release heat, and then becomes a high-temperature and high-pressure liquid, and then enters the accumulator 7. The refrigerant from the accumulator 7 is divided into two parts. One way enters the air-cooled evaporator I4 through the expansion valve I3, and absorbs the heat from the processing wind to assist the preliminary dehumidification; the other way enters the air-cooled evaporator II6 through the expansion valve II5, and absorbs the heat from the back air of the primary runner 13. .
高温热泵系统工作原理如下：经热泵压缩机8压缩后的高温高压制冷剂，经过风冷冷凝器Ⅱ9冷凝放热后，进入膨胀阀Ⅲ10节流形成温度相对较低的低压制冷剂，进入风冷蒸发器Ⅲ11吸热，最后进入热泵压缩机8入口完成整个循环。风冷蒸发器Ⅲ11的进风是来自于制冷系统风冷冷发器Ⅰ2的高温热风，从而保证热泵系统具有较高蒸发温度，这样可以使冷凝器最大限度的加热再生风，且同时保证系统具有较高的能效。The working principle of the high-temperature heat pump system is as follows: the high-temperature and high-pressure refrigerant compressed by the heat pump compressor 8, after being condensed and released by the air-cooled condenser II9, enters the expansion valve III10 to be throttled to form a relatively low-temperature low-pressure refrigerant, and enters the air-cooled condenser. Evaporator III11 absorbs heat, and finally enters the inlet of heat pump compressor 8 to complete the entire cycle. The air intake of the air-cooled evaporator III11 is the high-temperature hot air from the air-cooled chiller I2 of the refrigeration system, so as to ensure that the heat pump system has a high evaporation temperature, which can make the condenser heat the regeneration air to the maximum extent, and at the same time ensure that the system has a high evaporating temperature. Higher energy efficiency.
二级转轮除湿系统包括空气处理循环和再生风循环，所述空气处理循环中，新风和室内风混合以后通过风冷蒸发器Ⅰ4降温和辅助除湿，然后进入一级转轮13进行除湿，再进入风冷蒸发器Ⅱ6降温，然后进入二级转轮15进行二级除湿，最后经过电加热器Ⅲ17处理到相应的温度。所述再生风循环中，新风与二级转轮15出来的再生风通过显热交换器16升温后，进入风冷冷凝器Ⅱ9进行二次加热，通过电加热器Ⅰ12后再进入一级转轮13，然后进入电加热器Ⅱ14，再进入二级转轮15，出来后进入显热交换器16，最后排入大气。The two-stage runner dehumidification system includes an air treatment cycle and a regeneration air cycle. In the air treatment cycle, after the fresh air and indoor air are mixed, they pass through the air-cooled evaporator I4 for cooling and auxiliary dehumidification, and then enter the first-stage runner 13 for dehumidification. Enter the air-cooled evaporator II6 to cool down, then enter the secondary runner 15 for secondary dehumidification, and finally treat it to the corresponding temperature through the electric heater III17. In the regenerated air cycle, the fresh air and the regenerated air from the secondary runner 15 are heated through the sensible heat exchanger 16, then enter the air-cooled condenser II9 for secondary heating, and then enter the primary runner after passing through the electric heater I12. 13, and then into the electric heater II 14, and then into the secondary runner 15, after coming out, into the sensible heat exchanger 16, and finally discharged into the atmosphere.
