Described flow is adjustable, and supply air line comprises ventpipe, and ventpipe begins to be serially connected with the second gate valve, first flow variable valve, the 3rd gate valve, the 4th gate valve, second adjustable valve, the 5th gate valve successively from its inlet end; Communicating pipe is provided with between ventpipe and direct air-supply duct, communicating pipe, one end was communicated with the portions between the first gate valve and the 7th gate valve of direct air-supply duct, communicating pipe, the other end was communicated with the portions between the 3rd gate valve and the 4th gate valve of ventpipe, was serially connected with the 6th gate valve communicating pipe.
The desorption gas that PSA device produces just can be delivered in converter and burn by arranging air delivery device by the utility model, and air delivery device is only made up of pipeline and serial connection gate valve thereon and flow control valve, and thus structure is simple.
The utility model not only structure is simple, and cost of manufacture is low, and can bring following beneficial effect.The desorption pneumatic transmission of torch process of setting fire is entered converter as fuel, greatly can reduce the gas consumption of converter, save resource, reduced energy consumption.Such as converter does not use amount of consumed gas during desorption gas to be 1088NM
3/ h, after using desorption gas, its gas consumption is 377NM
3/ h, combustion gas reduction effect is obvious.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is structural principle schematic diagram of the present utility model.
Embodiment
The desorption gas air feeder of converter as shown in Figure 1, comprise PSA device 1 and the converter 2 of device for producing hydrogen, converter 2 is provided with fuel gas inlet 15, PSA device 1 and converter 2 is existing production unit, and its structure and mode of operation do not repeat them here.The utility model has done following improvement on the basis of existing apparatus, between PSA device 1 and converter 2, is namely provided with the desorption gas that PSA device 1 can be produced is delivered to air delivery device in converter 2.
Above-mentioned air delivery device comprises the rear pneumatic tube 4 of front pneumatic tube 3 that inlet end is communicated with the desorption gas relief outlet of PSA device 1 and outlet side and converter 2 inner space, is provided with the air supply plant be communicated with rear pneumatic tube 4 inlet end front pneumatic tube 3 outlet side between front pneumatic tube 3 and rear pneumatic tube 4.Above-mentioned air supply plant comprise one end is communicated with front pneumatic tube 3 outlet side, the other end is communicated with rear pneumatic tube 4 inlet end direct air-supply duct 5 and with the adjustable supply air line of flow that direct air-supply duct 5 is arranged in parallel, direct air-supply duct 5 is serially connected with the first gate valve 6 and the 7th gate valve 17.Above-mentioned flow is adjustable, and supply air line comprises ventpipe 7, ventpipe 7 one end is communicated with front pneumatic tube 3, the other end is communicated with rear pneumatic tube 4, and ventpipe 7 begins to be serially connected with the second gate valve 7, first flow variable valve 8, the 3rd gate valve 9, the 4th gate valve 10, second adjustable valve 11, the 5th gate valve 12 successively from its inlet end; Communicating pipe 13 is provided with between ventpipe 7 and direct air-supply duct 5, communicating pipe 13, one end was communicated with the portions between the first gate valve 6 and the 7th gate valve 17 of direct air-supply duct 5, communicating pipe 13, the other end was communicated with the portions between the 3rd gate valve 9 and the 4th gate valve 10 of ventpipe 7, was serially connected with the 6th gate valve 14 communicating pipe 13.
