催化燃烧设备的生产目的是为了环保。是工业方面的废气污染的处理。在工业生产中,有大量的含苯类、醇类、酮类等有机废气散发。危害工人的健康并污染环境。催化燃烧设备厂家所提供的催化燃烧装置作为一种治理有机废气污染的手段,在我国取得了相当大的成效。但是在催化燃烧装置的设计、加工、应用过程中,还存在一些潜在的危险因素。在北京、上海、沈阳等地曾出现过因预防措施不得力而发生起火、爆炸的事故。因此应用催化燃烧设备的避免危险事故的发生应引起足够的重视。
The production purpose of catalytic combustion equipment is for environmental protection. The focus is on the treatment of industrial waste gas pollution. In industrial production, a large amount of organic waste gas containing benzene, alcohol and ketone is emitted. Endanger the health of workers and pollute the environment. The catalytic combustion device provided by the catalytic combustion equipment manufacturers, as a means of treating organic waste gas pollution, has achieved considerable results in China. However, there are still some potential risk factors in the design, processing and application of catalytic combustion device. In Beijing, Shanghai, Shenyang and other places, there have been fire and explosion accidents due to ineffective preventive measures. Therefore, enough attention should be paid to the application of catalytic combustion equipment to avoid the occurrence of dangerous accidents.
事故隐患,重时装置将发生火灾和爆炸。为此,应统一制定关于催化燃烧设备治理有机废气的浓度控制标准或设计规范。除上述因素外,从技术角度考虑以下几点危险因素也值得注意:
Fire and explosion will occur in the heavy time device. Therefore, the concentration control standards or design specifications for the treatment of organic waste gas by catalytic combustion equipment should be unified. In addition to the above factors, the following risk factors should also be noted from a technical point of view:
一、有机气体的爆炸下限与温度有关。通常,温度愈高,反应速度愈快,爆炸范围愈大。当进入催化燃烧装置的有机废气浓度过大时,催化燃烧装置的温度将会升高,加之自前国产催化燃烧装置均未设置废气浓度检测和控制设备,而温度升高后的有机废气的爆炸下限值将比手册给出的值要小,再加上装置中有机废气成分混合的不均匀性,在局部区域可能_过高温条件下废气的真实爆炸下限,则有爆炸的危险。
催化燃烧设备
1、 The lower explosion limit of organic gas is related to temperature. Generally, the higher the temperature, the faster the reaction speed and the larger the explosion range. When the concentration of organic waste gas entering the catalytic combustion device is too high, The temperature of catalytic combustion device will rise, and since the previous domestic catalytic combustion device has not been equipped with exhaust gas concentration detection and control equipment, the lower explosion limit of organic exhaust gas after the temperature rise will be smaller than the value given in the manual. In addition, due to the non-uniformity of organic exhaust gas composition mixing in the device, the explosion limit of organic exhaust gas may increase in some areas_ If the explosion limit of exhaust gas is too high, there is a risk of explosion.
二、一般来讲,大多数有机废气中的有机成份在同样爆炸下限浓度下,所含的燃烧热值可视为相同值,每1%的爆炸下限值约含热值1868千焦/牛·米勺如果全都燃烧,即热值全部用于使废气本身升温,则1%的爆炸下限值的废气燃烧可使废气升温15.3℃;当废气浓度达到25%的爆炸下限值时,可使废气本身温度升高。催化燃烧设备厂家提醒您时刻谨记这些注意问题。
2、 Generally speaking, the combustion calorific value of the organic components in most organic waste gas can be regarded as the same value under the same lower explosive limit concentration, and each 1% lower explosive limit value contains about 1868 kJ / N · m spoon. If all the components are burned, that is, the calorific value is used to raise the temperature of the waste gas itself, the combustion of 1% lower explosive limit value can raise the temperature of the waste gas by 15.3 ℃; when the concentration of the waste gas reaches 25% The temperature of the exhaust gas can be increased when the explosion limit is lower than the explosion limit. The manufacturers of catalytic combustion equipment remind you to keep these problems in mind at all times.
