當(dāng)沼氣壓力不滿足用氣要求時(shí)，應(yīng)設(shè)置沼氣專用增壓機(jī)。沼氣火炬的燃燒壓力為1.5～2.0kpa,

When the pressure of biogas does not meet the gas requirements, a dedicated biogas booster should be installed. The combustion pressure of biogas torch is 1.5-2.0 kPa,

那么當(dāng)沼氣壓力不滿足火炬燃燒壓力時(shí)就需要加增壓機(jī)；

So when the biogas pressure does not meet the torch combustion pressure, a booster needs to be added;

垃圾填埋場沼氣燃燒火炬,需要加增壓機(jī)；

The biogas combustion torch at the landfill site requires the addition of a booster compressor;

有小伙伴又會(huì)問了，需要用哪種增壓機(jī)呢？

Some friends may ask again, which type of turbocharger do you need?

羅茨鼓風(fēng)機(jī)和離心鼓風(fēng)機(jī)是沼氣工程中常用的增壓設(shè)備；

Roots blower and centrifugal blower are commonly used boosting equipment in biogas engineering;

羅茨鼓風(fēng)機(jī)屬于恒流風(fēng)機(jī)，工作的主要參數(shù)是流量，輸出壓力隨管道和負(fù)載的變化而變化，流量變化很小。

Roots blower belongs to constant flow fan, and its main working parameter is flow rate. The output pressure varies with the changes in pipeline and load, and the flow rate changes very little.

如果負(fù)載需要恒壓效果，則使用離心風(fēng)機(jī)，因?yàn)殡x心風(fēng)機(jī)屬于恒壓風(fēng)機(jī)。工作的主要參數(shù)是風(fēng)壓。輸出流量隨管道和負(fù)載的變化而變化，壓力變化不大。當(dāng)多臺(tái)鼓風(fēng)機(jī)并聯(lián)運(yùn)行時(shí)，由于并聯(lián)影響，流量減少。一般來說，兩臺(tái)羅茨鼓風(fēng)機(jī)并聯(lián)時(shí)的流量損失約為10%，兩臺(tái)離心鼓風(fēng)機(jī)并聯(lián)時(shí)的流量損失則大于10%。

If the load requires constant pressure effect, a centrifugal fan should be used because centrifugal fans belong to constant pressure fans. The main parameter of work is wind pressure. The output flow rate varies with changes in the pipeline and load, while the pressure does not change significantly. When multiple blowers run in parallel, the flow rate decreases due to the parallel effect. Generally speaking, the flow loss when two Roots blowers are connected in parallel is about 10%, while the flow loss when two centrifugal blowers are connected in parallel is greater than 10%.

可以根據(jù)現(xiàn)場的實(shí)際工況來選擇哦。

You can choose according to the actual working conditions on site.

增壓機(jī)選型要注意以下幾點(diǎn)：

When selecting a turbocharger, the following points should be noted:

1、增壓機(jī)流量按用戶小時(shí)非常大用氣量確定，壓力按用戶需要的非常高壓力和增壓機(jī)出口至用戶之間的非常大阻力之和確定;

1. The flow rate of the turbocharger is determined based on the maximum hourly gas consumption of the user, and the pressure is determined based on the maximum pressure required by the user and the sum of the maximum resistance between the turbocharger outlet and the user;

2、非常好買兩臺(tái)增壓機(jī)組，一用一備；

2. It is best to buy two booster units, one for use and one for backup;

3、各增壓系統(tǒng)應(yīng)設(shè)置止回閥,阻火器，回流管道，自動(dòng)切斷閥，壓力變送器等；

3. Each boosting system should be equipped with check valves, flame arresters, return pipes, automatic shut-off valves, pressure transmitters, etc;
