为了让含有硫化氢等腐蚀性的气体适合发电机组、沼气炉等设备使用，必须对沼气进行处理。我们一般采用经济实惠的干式脱硫法。主要设备有：脱硫塔、 缓冲罐、脱水器、正负压、智能控制柜等部件组成。对去除硫化氢、水分等具有简单、管理方便、造价低、寿命长、运行可靠等优点。适用于硫化氢含量低，处量小，脱硫精度要求高的气体。
In order to make corrosive gases such as hydrogen sulfide suitable for use in power generation units, biogas furnaces, and other equipment, biogas must be treated. We generally use an economical dry desulfurization method. The main equipment consists of components such as desulfurization tower, buffer tank, dehydrator, positive and negative pressure, intelligent control cabinet, etc. It has the advantages of high efficiency, simple management, low cost, long service life, and reliable operation for removing hydrogen sulfide, moisture, etc. Suitable for gases with low hydrogen sulfide content, low gas processing capacity, and high desulfurization accuracy requirements.
脱硫系统的设计：
Design of desulfurization system:
根据用户的实际气体数量和气体中硫化氢的含量，专门量身设计脱硫各个系统的外形尺寸和内部结构。所以，对于不同类型的气体、不同硫化氢含量、不同压力的气体，脱硫设备的外形尺寸与内部结构也有所不同。
According to the user's Real gas quantity and hydrogen sulfide content in the gas, the overall dimensions and internal structure of each desulfurization system are specially designed. So, for different types of gases, different hydrogen sulfide content, and different pressures, the external dimensions and internal structure of desulfurization equipment also vary.
为实时监控再生过程中硫化物及硫化物与空气中的氧气反应速度，可以增加温度监控设备，避免因再生过程中进入的空气量过大，放热反应剧烈，温度超过脱硫剂的燃点而导致发生意外火灾等意外。
In order to monitor the reaction rate of sulfide and sulfide with oxygen in the air during the regeneration process in real time, temperature monitoring equipment can be added to avoid accidental fire caused by excessive amount of air entering during the regeneration process, severe Exothermic reaction, and temperature exceeding the ignition point of the desulfurizer.
沼气脱硫的必要性：
The necessity of biogas desulfurization:
沼气脱硫剂是一种安装在沼气脱硫器内的颗粒状、可以通过化学反应去除硫化氢的物质。它的作用是除去从沼气池中输送来的硫化氢气体，该气体具有臭鸡蛋味，沼气通过脱硫剂吸收过滤就可去掉这种臭味，变成真正的和干净的沼气燃料。否则，含有硫化氢的沼气燃烧后会变成二氧化硫等气体，不但对人的器官造成危害，还会腐蚀沼气灶、炊具、发电机组等设备，缩短这些设备的使用寿命，增加故障率等。所以，及时更换脱硫剂是正确使用沼气的重要措施。
Biogas desulfurizer is a granular substance installed in a biogas desulfurizer that can remove hydrogen sulfide through chemical reactions. Its function is to remove the hydrogen sulfide gas transported from the biogas digester, which has a foul egg odor. The biogas can be absorbed and filtered by desulfurization agents to remove this odor and become a truly safe and clean biogas fuel. Otherwise, biogas containing hydrogen sulfide will become sulfur dioxide and other gases after combustion, not only causing harm to human organs, but also corroding equipment such as biogas stoves, cooking utensils, and power generators, shortening the service life of these equipment and increasing the failure rate. Therefore, timely replacement of desulfurizers is an important measure for the correct use of biogas.
脱硫剂的使用方法：
Method of using desulfurizer:
根据沼气脱硫剂使用的实际情况，一般使用3-6个月必须更换。关闭沼气脱硫塔的开关，打开沼气脱硫塔进出料口，将脱硫剂掏净，关闭出料口，在进料口填装新脱硫塔，填满后封闭进料口。 更换下的脱硫剂还可再次使用，方法是：将更换下来的脱硫剂先除去碎沫和杂物等，再把颗粒型剂放在阴凉、通风、干燥处2-4天，等到脱硫剂的颜色变成褐色之后，用塑料袋密封起来，不让其受潮、曝晒、压碎，等下次更换使用。换下来的脱硫剂多只能再用两次，再次使用时间只能在3-6个月。
According to the actual situation of using biogas desulfurizers, they must be replaced after 3-6 months of use. Firstly, turn off the switch of the biogas desulfurization tower, open the inlet and outlet of the biogas desulfurization tower, remove the desulfurizer, close the outlet, fill the inlet with a new desulfurization tower, and then close the inlet. The replaced desulfurizer can also be used again. The method is to first remove the broken foam and debris from the replaced desulfurizer, and then place the granular agent in a cool, ventilated, and dry place for 2-4 days. After the color of the desulfurizer turns brown, seal it with a plastic bag to prevent it from getting damp, exposed to sunlight, or crushed, and wait for the next replacement. The replaced desulfurizer can only be reused twice at most, and the reuse time can only be 3-6 months.
