　　yl6809永利 -三、干法、湿法、生物脱硫的比较

　　Biogas desulfurization - Comparison of dry, wet and biological desulfurization

　　1.干法脱硫的特点

　　1. Characteristics of dry desulfurization

　　①结构简单，使用方便。

　　① The structure is simple and easy to use.

　　②工作过程中无需人员值守，定期换料，一用一备，交替运行。

　　② In the process of operation, there is no need for one on duty.

　　③脱硫率新原料时较高，后期有所降低。

　　③ The desulfurization rate of new raw materials was higher than that of new raw materials, but decreased in the later stage.

　　④与湿式相比，需要定期换料。

　　④ Periodic refuelling is required compared to wet.

　　⑤运行费用偏高。

　　⑤ The operation cost is high.
生物脱硫

　　2.湿法脱硫的特点

　　2. Characteristics of wet desulfurization

　　①设备可长期不停的运行，连续进行脱硫。

　　① The equipment can operate continuously for a long time.

　　②用PH值来保持脱硫效率，运行费用低。

　　② Using pH value to keep desulfurization efficiency is low.

　　③工艺复杂需要专人值守。

　　③ The process is complex and requires special personnel on duty.

　　④设备需保养。

　　④ The equipment needs maintenance.

　　3.生物脱硫的特点

　　3. Characteristics of biological desulfurization

　　①不需催化剂和氧化剂(空气除外)。

　　① No catalyst and oxidant (except air) is required.

　　②不需处理化学污泥。

　　② There is no need to treat chemical sludge.

　　③产生很少生物污染，低能耗，回收硫，效率高，无臭味。

　　③ It produces little biological pollution, low energy consumption, sulfur recovery, high efficiency and no odor.

　　④缺点是过程不易控制，条件要求苛刻等。

　　④ The disadvantages are that the process is not easy to control and the conditions are demanding.

　　脱硫剂怎样进行再生？

　　How to regenerate desulfurizer?

　　脱硫剂再生的方法是：将失去活性的脱硫剂取出，均匀疏松地摊放在平整、干净、背阳、通风的场地，经常翻动脱硫剂，使其与空气充分接触，氧化再生。

　　The regeneration method of desulfurizer is as follows: take out the deactivated desulfurizer, spread it evenly and loosely in a flat, clean, sunny and ventilated place, and often turn the desulfurizer to make it fully contact with the air for oxidation regeneration.

　　yl6809永利 - 脱硫技术特点：

　　Characteristics of biogas desulfurization desulfurization technology:

　　1、天然气净度可根据实际需要调节，可以平稳的控制煤气中的H2S的含量。

　　1. The purity of natural gas can be adjusted according to the actual needs, and the content of H2S in the gas can be controlled smoothly.

　　2、与干法脱硫相比，虽然投资是干法脱硫的2-3倍，但是运行成本低，1000Nm?实际脱硫费用为4元左右，避免了干式脱硫系统因脱硫剂再生后脱硫效果差及硫的吸附等原因而导致的生产成本增加的问题。

　　2. Compared with dry desulfurization, although the investment is 2-3 times of that of dry desulfurization, the operation cost is low. The actual desulfurization cost of 1000nm? Is about 4 yuan, which avoids the production cost increase of dry desulfurization system due to poor desulfurization effect after regeneration of desulfurizer and sulfur adsorption.

　　3、具有操作稳定、运行安全，脱硫效率高的特点。脱硫效率可达到97%以上,脱硫后煤气中H2S含量<50mg/Nm3。

　　3. It has the characteristics of stable operation, safe operation and high desulfurization efficiency. The desulfurization efficiency can reach more than 97%, and the content of H2S in the gas after desulfurization is less than 50mg / Nm3.

　　4、如果脱硫催化剂是PDS或’888’,不但能脱除H2S而且能脱煤气中占总硫含硫10%左右的部分有机硫。

　　4. If the desulfurization catalyst is PDS or '888', not only H2S can be removed, but also some organic sulfur which accounts for about 10% of the total sulfur in the gas can be removed.

　　湿法天然气脱硫技术适用范围：

　　Application scope of wet natural gas desulfurization technology:

　　适用于各种煤气、沼气和天然气的脱硫(H2S)。

　　It is suitable for desulfurization (H2S) of gas, biogas and natural gas.
