催化燃烧工作怎样保证其安全性
1. Adsorption and concentration of waste gas: the adsorption and concentration of waste gas mainly use the adsorption of activated carbon. This set of equipment consists of several sets of activated carbon adsorption boxes. In the process of system operation, open a set of activated carbon adsorption box to adsorb and concentrate industrial waste gas. After the first group of activated carbon is saturated, open the two groups of activated carbon adsorption box, and carry out the adsorption process similar to the first group of activated carbon adsorption box. When the two groups of activated carbon adsorption boxes work, the first group of activated carbon adsorption boxes desorb. By analogy, the activated carbon adsorption box in this system circulates the adsorption and desorption process. The desorbed industrial waste gas enters the catalytic combustion equipment and is oxidized and decomposed into non-toxic and harmless small molecular compounds, which can meet the emission standard.
2.废气催化燃烧:催化燃烧设备主要由换热器、催化床、电加热器、燃烧室、蓄热器等几个主要部件组成。加热管首先加热催化燃烧设备,通过风机的作用提供活性炭脱附的温度(80-120℃),脱附的有机废气再次进入催化燃烧设备,废气在燃烧室中的催化床的作用下在250-350℃氧化分解为水和二氧化碳等小分子化合物。通过热交换器达到标准的热回收利用,达到节能的目的。
2. Exhaust gas catalytic combustion: the catalytic combustion equipment is mainly composed of heat exchanger, catalytic bed, electric heater, combustion chamber, heat accumulator and other main components. The heating tube first heats the catalytic combustion equipment, and provides the temperature of activated carbon desorption (80-120 ℃) through the action of the fan. The desorbed organic waste gas enters the catalytic combustion equipment again. Under the action of the catalytic bed in the combustion chamber, the waste gas is oxidized and decomposed into water, carbon dioxide and other small molecular compounds at 250-350 ℃. Through the heat exchanger to achieve standard heat recovery and utilization, to achieve the purpose of energy saving.
催化燃烧设备适用于处理高温、高浓度、连续性产生的有机废气,不会产生二次污染。催化低温分解,预热时间段,能耗低,催化剂使用寿命长,,净化率高达975以上。运行中可以实现全自动控制,设备运行稳定,检查系统的配置完善,操作维护非常方便。
Catalytic combustion equipment is suitable for the treatment of organic waste gas with high temperature, high concentration and continuity, without secondary pollution. Catalytic decomposition at low temperature, preheating time, low energy consumption, long service life of catalyst, purification rate up to 975. It can realize full-automatic control in operation, the equipment runs stably, the configuration of the inspection system is perfect, and the operation and maintenance is very convenient.
1、气流和温度均匀分布。燃烧室需要具有足够的长度和空间,以使气流和催化剂表面的温度分布均匀,并确保火焰不会直接接触催化剂表面。催化燃烧装置应具有良好的保温效果。一般来说,炉体在钢结构外壳内衬有耐火材料或双层夹层壁结构。
1. The air flow and temperature are evenly distributed. The combustion chamber needs to have enough length and space to make the temperature distribution of gas flow and catalyst surface uniform, and ensure that the flame does not directly contact the catalyst surface. The catalytic combustion device should have good thermal insulation effect. Generally speaking, the furnace body is lined with refractory material or double-layer sandwich wall structure in the steel structure shell.
2、便于清洗和更换。一般来说,催化剂反应器应设计成装卸方便的模具抽屉结构,便于清洗和更换催化剂载体。
2. Easy to clean and replace. Generally speaking, the catalyst reactor should be designed with a mold drawer structure which is convenient for loading and unloading, so as to facilitate the cleaning and replacement of catalyst carrier.
3、辅助燃料和助燃。催化燃烧一般使用天然气作为辅助燃料,也可以使用燃料油、电加热等作为辅助燃料。通常,净化气体用于燃烧支持。如果净化后的气体不能用于助燃,应引入空气用于助燃。
3. Auxiliary fuel and combustion supporting. Catalytic combustion generally uses natural gas as auxiliary fuel, and fuel oil and electric heating can also be used as auxiliary fuel. In general, purified gases are used for combustion support. If the purified gas cannot be used for combustion support, air should be introduced for combustion support.
