Fu Fangzhong is the inventor and patent owner of the "new technology of zero residue biogas production by fecal grass mixed continuous fermentation". The "three-phase internal circulation biogas digester" developed by him has complete decomposition of raw materials, high gas production rate and convenient use. He was specially appointed as a researcher by the Institute of solid waste and sewage treatment of Beijing Zhongtian environmental protection and environmental science and Technology Research Institute. Recently, they signed a three party agreement with a science and technology company in Jiangsu to jointly apply for utility model patents, speed up the promotion and application, and share the achievements of "a training method of biological bacteria for biogas production from fully gasified straw in anaerobic system" developed on the basis of fufangzhong biogas new technology.
據(jù)介紹,沼氣中含有60%以上的甲烷,而汽車(chē)天然氣甲烷含量在90%以上
It is reported that biogas contains more than 60% methane, while the methane content of automobile natural gas is more than 90%
沼氣儲(chǔ)氣柜在實(shí)際使用中將配備安全水封配件,以在儲(chǔ)罐超壓時(shí)為合理的壓力釋放做準(zhǔn)備。發(fā)生超壓時(shí),氣體將通過(guò)水封排出,同時(shí)會(huì)混入大量的水。隨著水蒸氣的狀態(tài),水位將逐漸降低以達(dá)到泄壓的目的。如果雙膜儲(chǔ)氣柜的風(fēng)量較大,則會(huì)直接噴水,但這會(huì)導(dǎo)致保護(hù)器無(wú)法自行恢復(fù),因此需要手動(dòng)裝滿(mǎn)水。
The biogas gas holder will be equipped with safety water seal accessories in actual use to prepare for reasonable pressure release in case of overpressure of the storage tank. In case of overpressure, the gas will be discharged through the water seal and mixed with a large amount of water. With the state of water vapor, the water level will gradually decrease to achieve the purpose of pressure relief. If the air volume of the double membrane gasholder is large, it will spray water directly, but this will cause the protector to not recover by itself, so it needs to be filled with water manually.
一些制造商的沼氣儲(chǔ)氣柜沒(méi)有特殊的內(nèi)膜保護(hù)系統(tǒng),而僅使用超壓水封進(jìn)行保護(hù)。在正常操作下,外膜可以抵消內(nèi)膜的壓力,但是當(dāng)外膜出乎意料地發(fā)生故障時(shí),或者由于電力系統(tǒng)無(wú)法及時(shí)提供壓力時(shí),內(nèi)膜會(huì)過(guò)壓,并且超壓容易泄漏。如果內(nèi)膜泄漏,則外膜和外膜將形成混合氣體。非常危險(xiǎn)因此,氣罐的水封通常填充有防凍劑以應(yīng)對(duì)寒冷季節(jié)地區(qū)。
Some manufacturers do not have special inner membrane protection system for biogas gas storage cabinets, but only use overpressure water seal for protection. Under normal operation, the outer membrane can counteract the pressure of the inner membrane, but when the outer membrane fails unexpectedly or the power system cannot provide pressure in time, the inner membrane will overpressure and the overpressure is easy to leak. If the inner membrane leaks, the outer membrane and the outer membrane will form a gas mixture. Very dangerous, so the water seal of the air tank is usually filled with antifreeze to deal with cold season areas.
1、儲(chǔ)氣罐的材料選擇非常重要。材料的質(zhì)量決定了整個(gè)儲(chǔ)氣罐的質(zhì)量和壽命。通常,選擇具有強(qiáng)拉伸強(qiáng)度,抗腐蝕,抗紫外線(xiàn)以及耐酸和堿的氟化物材料,并非所有的含氟或涂氟材料都是合適的。必須使用特殊的復(fù)合材料以確保使用壽命。通常,使用具有良好的柔韌性,強(qiáng)的拉伸強(qiáng)度,緊湊的復(fù)合材料,良好的氣密性和防腐性的材料。
1. The material selection of air storage tank is very important. The quality of materials determines the quality and service life of the whole air storage tank. Generally, fluoride materials with strong tensile strength, corrosion resistance, UV resistance and acid and alkali resistance are not suitable for all fluorine-containing or fluorine-coated materials. Special composite materials must be used to ensure service life. Generally, materials with good flexibility, strong tensile strength, compact composites, good air tightness and corrosion resistance are used.
2、材料的抗老化性能很好,但物理性能很差,很容易損壞。不太的人看不到一般性損壞,但是將來(lái)使用壽命會(huì)受到影響。因此,需要更多的人員來(lái)進(jìn)行制作和安裝,并且在制作和安裝過(guò)程中應(yīng)使材料的特性更加清晰。高品質(zhì)只能通過(guò)避免容易引起的質(zhì)量問(wèn)題來(lái)實(shí)現(xiàn)。該材料的設(shè)計(jì)壽命通常為15年。
2, the anti-aging properties of materials are very good, but their physical properties are very poor, so they are easy to damage. Less professional people can't see the general damage, but the service life will be affected in the future. Therefore, more professionals are needed for fabrication and installation, and the characteristics of materials should be clearer in the process of fabrication and installation. High quality can only be achieved by avoiding easily caused quality problems. The design life of this material is usually 15 years.
3、由于雙膜氣體保持器的正常運(yùn)行在壓力下,因此控制和保護(hù)裝置在實(shí)際工作中尤為重要。特別是當(dāng)它用作反應(yīng)器頂部和蓋子的集成設(shè)備時(shí)。一方面,所使用的材料或制造工藝不符合相應(yīng)的要求,另一方面,這是由于相關(guān)保護(hù)措施不足所致。因此,在使用時(shí)必須使用高精度和可靠的安全保護(hù)裝置。
3. Since the normal operation of the double film gas holder is under pressure, the control and protection device is particularly important in practical work. Especially when it is used as an integrated device for the top and cover of the reactor. On the one hand, the materials or manufacturing processes used do not meet the corresponding requirements, on the other hand, this is due to the lack of relevant protective measures. Therefore, high-precision and reliable safety protection devices must be used.
4、目前,沼氣儲(chǔ)氣柜有自己的控制方法。它可以自動(dòng)解決一些問(wèn)題,從而減輕用戶(hù)的壓力。除了材料,控制和保護(hù)設(shè)備,制造過(guò)程以及維護(hù)外,以后的使用也是極大地影響其使用壽命的因素。畢竟,儲(chǔ)氣柜并不像家用電器那樣智能,只要插上電源就可以使用。使用它們時(shí),對(duì)用戶(hù)進(jìn)行技術(shù)培訓(xùn)非常重要。實(shí)際上,通過(guò)用戶(hù)的初步判斷可以避免許多故障。
4. At present, the biogas gas holder has its own control method. It can automatically solve some problems, so as to reduce the pressure of users. In addition to materials, control and protection equipment, manufacturing process and maintenance, future use is also a factor that greatly affects its service life. After all, the gas conservator is not as smart as household appliances. It can be used as long as the power is plugged in. When using them, technical training for users is very important. In fact, many faults can be avoided through the user's preliminary judgment.
