Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, real with concrete below in conjunction with the accompanying drawings The present invention is further detailed explanation to execute mode.
As depicted in figs. 1 and 2, the preferred embodiments of the present invention provide a kind of passive hydrogen and CO device of disappearing, described non- Active disappear hydrogen and CO device includes housing 3, and the hydrogen module that disappears, disappear CO module 2;Wherein, disappear described in hydrogen module and the CO module 3 that disappears Layered arrangement is in described enclosure interior.This device is used for eliminating fuel gas such as hydrogen and CO and exceedes LEL (such as content More than 10%) rich air, and combustion explosion of combustible gas can be prevented.
Preferably, the hydrogen module that disappears described in is made up of, in like manner some hydrogen unit that disappear being arranged in parallel at a distance of certain pitch space The CO module that disappears also is made up of some CO unit that disappear being arranged in parallel at a distance of certain pitch space.This disappear hydrogen unit and the CO unit structure that disappears Part pattern can be not only used for passive passive hydrogen and the CO of disappearing, it may also be used for disappearing hydrogen and CO by dynamic formula of active high throughput.
Preferably, the hydrogen unit that disappears described in is lamellar.
Preferably, the hydrogen unit that disappears described in is box-like.
Preferably, the CO unit that disappears described in is lamellar.
Preferably, the CO unit that disappears described in is box-like.
Preferably, disappear hydrogen module described in and the quantity of the CO module 2 that disappears is three layers, including first set gradually from the bottom up Layer disappears hydrogen module, the second layer disappears CO module and third layer disappears hydrogen module.Ground floor module is for by combustible gas higher for concentration Body tentatively eliminates, to be lowered into the combustable gas concentration in second layer module, after second layer module, and fuel gas Concentration reduces further, hence into third layer assembly module, reduces combustable gas concentration in this way and prevents the generation of blast.
