空压机节能改造需要处理哪些?

1.变频调速方式

1. frequency conversion speed regulation mode
采取变频调速方式来降低空压机电动机的轴功率输出。改造之前,空压机的压力达到设定压力时,即会自动卸荷;改造之后,空压机并不卸荷,而是通过降低转速来降低压缩机时的产气量,维持气网需要的最低压力。这里有两个地方可以节能:
The frequency conversion speed regulation method is adopted to reduce the shaft power output of the air compressor motor. Before modification, the air compressor will unload automatically when the pressure reaches the set pressure; after modification, the air compressor does not unload, but reduces the gas production of the compressor by reducing the rotational speed to maintain the minimum pressure required by the gas network. There are two ways to save energy.
(1)减少压缩机从卸荷状态到加载状态这一突变过程带来的电能消耗。
(1) reduce the power consumption caused by the sudden change of the compressor from unloading state to loading state.
(2)电机的运转频率降低至工频以下,使电机轴的输出功率减少。
(2) the running frequency of the motor is reduced to below the power frequency, so that the output power of the motor shaft is reduced.
以上两种方式都不同程度的降低了空压机在运行过程中的能源消耗,但是空压机在工作过程中产生如此大的热能而让它白白地散发到空气中去,却在很长的时间内未得到用户的普遍重视,这不能说不是一个极大的遗憾。所以说,好的解决方案也是德蒙空压机服务客户的追求之处。
The above two ways have reduced the energy consumption of air compressor in different degrees, but it is not a great pity that the air compressor produces so much heat energy in the process of working and let it emit into the air in vain, but it has not been paid attention to by users in a long time. Therefore, a good solution is also the pursuit of customer service of de Meng air compressor.
2.集中控制方式
2. centralized control mode
对多台空压机采取集中控制方式。根据用气情况自动控制空压机的运行台数,改造之前,空压机开启的台数是固定的。

Centralized control mode is adopted for multiple air compressors. According to the use of gas, the number of air compressor running tables is automatically controlled. Before the transformation, the number of air compressor opening tables is fixed.
(1)若用气量进一步减少,性能好的空压机则会自动停机。在(1)的情况下,空压机即使是在卸载情况下也是要消耗电能的。改造后,便可停掉相应台数的空压机,运行台数减少了,无疑就节约了用电。
(1) if the volume of gas is further reduced, the air compressor with good performance will stop automatically. In the case of (1), air compressors consume energy even under unloading conditions. After the transformation, the corresponding number of air compressors can be stopped, and the number of operating units has been reduced, thus saving electricity undoubtedly.
(2)当用气减少到一定量时,空压机是通过减少加载时间来减少产气量。
(2) when the gas consumption is reduced to a certain amount, the air compressor reduces the gas production by reducing the loading time.
3.余热回收
3. waste heat recovery
空压机余热回收是一项非常环保的节能方式,也是目前备受推崇的节能方式。空压机余热回收是将空压机的高温油经过热交换等技术处理把热量传递到冷水中,冷水被加热后流到保温贮水桶中,这样就可达到热能回收的目的。
Waste heat recovery of air compressor is a very environmentally friendly energy-saving way, and it is also a highly respected energy-saving way at present. The waste heat recovery of air compressor is to transfer heat from high-temperature oil of air compressor to cold water through heat exchange and other technical treatments, and then the cold water is heated and flowed into the thermal storage bucket, so as to achieve the purpose of heat energy recovery.
因为空压机百分之七十三的热能都在油中,而对油进行技术处理换热,达到的结果就会产生源源不断的热水,即能达到空压机在恒温状态下工作,又能满足工厂或者生活所需要的热水,一举两得,而且利用空压机余热回收技术产生的热水不需要任何额外费用,此举又减少了工厂为了制造热水的投资。
Because 73% of the heat energy of the air compressor is in the oil, and the technical treatment of heat transfer of the oil will produce a continuous stream of hot water, that is to say, the hot water that the air compressor can work at constant temperature and meet the needs of factories or life can be achieved by killing two birds with one stone, and the waste heat recovery technology of the air compressor can be used. The hot water produced does not require any additional cost, which reduces the investment of factories in order to make hot water.
