技术领域technical field
本实用新型涉及除尘设备技术领域，具体涉及一种用于家具厂的粉尘防爆处理系统。The utility model relates to the technical field of dust removal equipment, in particular to a dust explosion-proof treatment system for furniture factories.
背景技术Background technique
家具加工过程会产生大量粉尘，需要进行回收处理；由于家具粉尘属于易燃易爆粉尘，一旦有火星进入粉尘处理系统，就有可能引起火灾，甚至爆炸，会造成巨大的财产损失和安全事故。A large amount of dust is generated during furniture processing, which needs to be recycled. Since furniture dust is flammable and explosive dust, once sparks enter the dust treatment system, it may cause a fire or even explode, causing huge property losses and safety accidents.
现有的粉尘处理系统会在进气管和滤袋装置处设置泄爆片，在进气管内的压力过大时，或者滤袋装置内的压力过大时，上述的泄爆片打开，与大气连通进行泄压，使得系统不会发生爆炸。但是由于进气管的管径和滤袋装置内的粉尘含量很大，短时间内难以完全泄压，有一点火苗还是会直接引起爆炸，爆炸位置难以预估，存在很大的安全隐患。In the existing dust treatment system, explosion venting sheets are installed at the intake pipe and the filter bag device. When the pressure in the intake pipe or the filter bag device is too high, the above explosion venting sheet will be opened to communicate with the atmosphere. Connected for pressure relief, so that the system will not explode. However, due to the large diameter of the intake pipe and the large dust content in the filter bag device, it is difficult to completely release the pressure in a short time, and a little flame will directly cause an explosion. The location of the explosion is difficult to predict, and there is a great potential safety hazard.
