介绍了一种用于运输式或固定式柴油机的低电压排气烟尘滤清器。该滤清器由带负电的铁丝网板(负极)和带正电的装在钢板容器内的碳纤维毡组成。对这种装置的试验结果表明:①本装置具有良好的烟尘滤清效果,其烟尘浓度降低率可达到60％～70％;②在外加电压一定的条件下,滤清器的烟尘降低率,取决于由排气流速和烟尘捕集器(碳纤维客器)长度决定的接触速度,该速度越小,烟尘降低率就愈大;③通过振动使烟尘脱落而使滤清器获得再生,并且操作简便、安全。
A low-voltage exhaust soot filter for transport or stationary diesel engines is introduced. The filter consists of a negatively charged barbed wire (negative) and a positively charged carbon fiber mat housed in a steel plate container. The test results of this device show that: ① The device has a good soot filtration effect, the reduction rate of soot concentration can reach 60% ~ 70%; ② under the conditions of applied voltage, the filter soot reduction rate, Depends on the contact speed determined by the exhaust flow rate and the length of the soot trap (carbon fiber receptacle), the smaller this speed is, the larger the soot reduction rate is; (3) the filter is regenerated by shedding the soot by vibration, and the operation Simple and safe.
