在現(xiàn)代企業(yè)里,壓縮空氣的使用越來越普遍,常見的壓縮空氣干燥機(jī)主要有吸附式干燥機(jī)和冷凍式干燥機(jī)兩種。冷凍式干燥機(jī)與吸附式干燥機(jī)的不同之處是什么呢?
In modern enterprises, the use of compressed air is more and more common. The common compressed air dryers are adsorption dryer and freezing dryer. What is the difference between freeze dryer and adsorption dryer?
1工作原理上的不同
1. Different working principles
冷干機(jī)是根據(jù)冷凍除 濕原理,將來自上游的飽和壓縮空氣通過與冷媒的熱交換冷 卻到一定的溫度,凝析出大量的液態(tài)水,經(jīng)氣液分離器分離后自動(dòng)排出機(jī)外,從而達(dá)到除水干燥的目的。吸干機(jī)則是根據(jù)變壓吸附的原理,將來自上游的飽和壓縮空氣在一定的壓力下經(jīng)過與干燥劑的接觸,將絕大部分的水份吸附在干燥劑里,干燥空氣進(jìn)入下游工作,從而達(dá)到深 度干燥的目的。
According to the principle of freezing dehumidification, the chiller cools the saturated compressed air from upstream to a certain temperature through heat exchange with refrigerant, condenses out a large amount of liquid water, and automatically discharges it out of the chiller after separation by gas-liquid separator, so as to achieve the purpose of water removal and drying. Suction dryer is based on the principle of pressure swing adsorption, will come from the upstream saturated compressed air under a certain pressure through contact with the desiccant, the vast majority of moisture adsorption in the desiccant, dry air into the downstream work, so as to achieve the purpose of deep drying.

2除水效果上的不同
2. Different water removal effect
冷干機(jī)因?yàn)槭艿狡湓淼闹萍s,如果溫度太低的話會出現(xiàn)結(jié)冰現(xiàn)象,所以其的溫度通常在2~10℃。吸干機(jī)則因?yàn)闊o須通過溫度變化,而干燥劑(氧化鋁)則又可以進(jìn)行深 度干燥,所以通常其出口的溫度可以達(dá)到-20℃以下,也就是說可以達(dá)到深 度干燥。
Because of its principle, if the temperature is too low, there will be icing phenomenon, so its temperature is usually 2 ~ 10 ℃. The suction dryer does not need to change the temperature, and the desiccant (alumina) can carry out deep drying, so the outlet temperature of the suction dryer can reach below - 20 ℃, that is to say, it can achieve deep drying.
3能 量損耗上的不同
3. Difference in energy consumption
對于冷干機(jī)來說,因?yàn)橐ㄟ^冷媒壓縮作功方可達(dá)到冷 卻的目的,所以在電源功率上會偏高。而吸干機(jī)因?yàn)橹灰ㄟ^電控箱對閥門進(jìn)行控制而已,所以通常用電功率只有幾十瓦左右,也就是說不會有什么電量上的損耗。
For the cold dryer, because the purpose of cooling can only be achieved through refrigerant compression, so the power supply will be high. As long as the valve is controlled by the electric control box, the power consumption of the suction dryer is usually only about tens of watts, that is to say, there will be no power loss.
4氣量損耗的不同
4. Difference of gas loss
因?yàn)槔涓蓹C(jī)是通過變溫來達(dá)到除水的目的,水份又是通過自動(dòng)排水器排出機(jī)外,所以沒有氣量的損耗。而吸干機(jī)則因?yàn)楦稍飫┰谖柡秃笮枰?生,因些需要有12-15%左右的再 生氣損耗。
Because the cold dryer is to achieve the purpose of water removal by changing the temperature, and the water is discharged from the machine through the automatic drainer, so there is no loss of air volume. The dryer needs to be regenerated after water absorption saturation, so it needs about 12-15% regeneration gas loss.
5故障率的不同
5 different failure rates
因?yàn)槔涓蓹C(jī)的冷媒系統(tǒng)和空氣系統(tǒng)包括電氣部分都相對復(fù)雜,而吸干機(jī)則只有閥門因要頻繁動(dòng)作而具有故障可能,所以在通常情況下吸干機(jī)的故障率要低過冷干機(jī)。
Because the refrigerant system and air system of the dryer, including the electrical part, are relatively complex, and only the valve of the dryer has the possibility of failure due to frequent action, so in general, the failure rate of the dryer is lower than that of the supercooled dryer.
總的說來,吸干機(jī)無論在穩(wěn)定性還是在效果上都要優(yōu)于冷干機(jī),只是因?yàn)橐獡p耗一定量的再 生氣,所在我們一般要客戶權(quán)衡利弊后作出選擇。不過現(xiàn)在已有越來越多的廠家選擇吸干機(jī),應(yīng)該說這在逐漸成為一種趨勢
Generally speaking, the suction dryer is better than the cold dryer in terms of stability and effect, just because it needs to consume a certain amount of regeneration gas, so we usually ask customers to weigh the pros and cons before making a choice. But now there are more and more manufacturers choose suction dryer, it should be said that this is gradually becoming a trend
