对病池的检修,通常包括以下内容: 1.察看管理系统(导气管、三通、开关等)及灯、炉具有否漏气; 2.检查活动盖是否封严; 3.检查进料管、出料间(水压间)与池体接合处是否接牢; 4.察看池体外观是否有缺陷,并检查池体本身是否有漏气现象。检查病池,常用气压法。对新建沼气池经过大出料进行清扫以后,将沼气池的入料口、出料间和活动盖用黄粘泥封牢,向池体内充气,使其气压达到设计压强,经过一段时间,观察气压表压力的变化来判断沼气池是否漏气,测得压强降低值与原设计压强的比值称之为漏损率。漏损率一般在5％以内认为是合格。作业人员在池内,通过听觉可以判定漏气的部位,边检查边修理,若遇有吱吱响的部位随即用砂浆或涂料进行修补。用此法维修病态池,省工、省料、效果好。
The maintenance of the sick pool, usually includes the following: 1. Check the management system (airway, tee, switches, etc.) and lights, whether the stove leaks; 2. Check the activities cover is sealed; 3. Check the feed pipe , Between the discharge room (water pressure) and the pool junction is firmly connected; 4. Look at the pool body appearance is flawed, and check the pool itself if there is leakage phenomenon. Check the sick pool, commonly used pressure method. After the new biogas digester is cleaned by large discharge, the inlet of the digester, the discharge chamber and the movable lid are sealed with yellow sticky mud to inflate the inside of the cell so that the pressure thereof reaches the design pressure. After a period of observation, Barometer pressure changes to determine whether the leaking gas digester, measured pressure reduction and the ratio of the original design pressure is called the leakage rate. Leakage rate is generally less than 5% is considered to be qualified. Operators in the pool, through the hearing can determine the leak site, while checking the repair side, in case of squeaky parts immediately with mortar or paint repair. Use this method to repair morbid pool, labor, material saving, good effect.
