  有很多人都不知道,干燥炉停机期间,不知道如何维护,我们公司给你今天,烘烤炉的维护,应该有很多人都不知道如何保持干燥炉的方法,今天,我给你的是干燥炉停机期间在三个主要的维护方法。
  There are many people who don't know how to maintain the drying oven during the shutdown period. Our company gives you today's maintenance of the baking oven. There should be many people who don't know how to maintain the drying oven. Today, I give you three main maintenance methods during the shutdown period of the drying oven.
  1. 碱液的方法。向锅中加入一定浓度的碱液,保持pH值在10以上。烘干热风炉的具体措施是:清除氧化皮和沉淀物,保证阀门紧固,与操作系统连接的管道设盲板。在锅炉的顶部位置可以安装一个小型的碱液罐,以保证在碱液丢失时进行补充。所用碱为Na2CO4、NaOH、Na3PO4或其混合物。准备时应使用软水,而不是原水。用量:Na2CO4每t锅加水20kg;每t锅水加入5 ~ 6kg NaOH。Na3PO4每t锅加10 ~ 12kg水,将碱液通过专用泵送至锅内,直到水从空气阀流出,保证锅内水压大于常压。保护初期应加强对系统的严格检查,正常后每月监测一次碱液浓度。当碱液浓度低于原注射浓度的5%时,应补充碱。
  1. Method of alkali solution. Add a certain concentration of alkali solution to the pot and keep the pH value above 10. The specific measures for drying the hot blast stove are: to remove oxide skin and sediment, to ensure that the valve is tight, and the pipeline connected with the operating system is provided with a blind plate. A small alkali liquor tank can be installed at the top of the boiler to ensure replenishment in case of alkali liquor loss. The alkali used is na2co4, NaOH, Na3PO4 or a mixture thereof. Soft water should be used in preparation, not raw water. Dosage: na2co4, 20kg water per T pot; 5 ~ 6kg NaOH per T pot. Add 10 ~ 12kg water to Na3PO4 every T pot, and pump the alkali solution into the pot through a special pump until the water flows out of the air valve, so as to ensure that the water pressure in the pot is greater than the atmospheric pressure. At the initial stage of protection, strict inspection of the system shall be strengthened, and the alkali concentration shall be monitored once a month after normal operation. When the concentration of alkali solution is lower than 5% of the original injection concentration, alkali should be added.

  2. 肼的方法。锅内充满肼(H2N2和氨(NH3)混合物)。防腐原理是利用肼的强还原性来去除水中的氧,使阴极极化。同时,氨在水溶液中呈碱性,可以提高pH值,钝化金属表面,引起阳极极化,达到防腐的目的。联氨因其毒性而受到限制。
  2. Hydrazine method. The pot is full of hydrazine (mixture of H2N2 and ammonia (NH3)). The anti-corrosion principle is to use the strong reducibility of hydrazine to remove the oxygen in water and make the cathode polarized. At the same time, ammonia is alkaline in aqueous solution, which can improve pH value, passivate metal surface, cause anode polarization, and achieve the purpose of anti-corrosion. Hydrazine is limited by its toxicity.
  3.有机缓蚀剂和阻垢剂。有机缓蚀剂和阻垢剂是天津市锅炉技术应用协会开发的一种水处理剂。其主要成分为聚磷酸盐、有机磷酸盐、BTA铜缓蚀剂和无机碱。药剂为棕红色液体,pH值13或以上,防腐机理为:试剂可以溶解在水中水解后带负电的聚磷酸根离子和带正电的阳离子聚磷酸根离子的金属腐蚀电池阳极区和价的结合,生成聚磷酸铁极难溶于水,并覆盖在金属表面形成的阳极区阳极极化,阳离子的水解金属在阴极区电子,与金属原子的亲和力很强,吸附在阴极区的金属表面,形成阴极极化。因此,对金属的腐蚀起到了扼死、防腐的作用。有机缓蚀剂和阻垢剂PH值≥13,用1L试剂处理4 ~ 5t水可以保证PH值≥10的水溶液,可以有效防止CO2气体引起的酸腐蚀,同时起到防腐作用。使用有机缓蚀剂作为废弃的维护剂时,其中的有机磷还可以溶解锅炉和纯碱水系统中的部分水垢和铁垢成分,使硬水垢成为结构疏松的多孔材料。同时,该剂能穿透水垢下,形成保护膜,破坏金属表面层与水垢的结合,使水垢脱落。
  3. Organic corrosion inhibitor and scale inhibitor. Organic corrosion inhibitor and scale inhibitor are a kind of water treatment agent developed by Tianjin Boiler Technology Application Association. Its main components are polyphosphate, organic phosphate, BTA copper corrosion inhibitor and inorganic base. The reagent is a brownish red liquid with a pH value of 13 or above. The anticorrosion mechanism is as follows: the reagent can dissolve the metal corrosion battery anode area and the combination of the negative polyphosphate ion and the positive cation polyphosphate ion after hydrolysis in water. The iron polyphosphate is very difficult to dissolve in water, and the anode area formed by covering the metal surface is anodized. The hydrolyzed metal of the cation is electronic in the cathode area, It has a strong affinity with metal atoms, adsorbs on the metal surface of the cathode area and forms cathode polarization. Therefore, it has a strangling and antiseptic effect on the corrosion of metal. The pH value of organic corrosion inhibitor and scale inhibitor is not less than 13. Treating 4-5t water with 1L reagent can ensure the pH value is not less than 10. It can effectively prevent the acid corrosion caused by CO2 gas and play an anti-corrosion role. When the organic corrosion inhibitor is used as the abandoned maintenance agent, the organic phosphorus can also dissolve part of the scale and iron scale components in the boiler and soda water system, making the hard scale become porous material with loose structure. At the same time, the agent can penetrate under the scale, form a protective film, destroy the combination of metal surface layer and scale, and make scale fall off.
