Description

A kind of marsh gas power generation air inlet protection device
Technical field
The utility model belongs to Gas application technical field, particularly relates to a kind of marsh gas power generation air inlet protection device.
Background technology
The energy and environmental problem have become two big outstanding problem of today's society, non-renewable energy resources increasingly reduce and into In the case of this is increasingly elevated, big-and-middle-sized biogas engineering is one of important means for solving the energy and environmental problem, and biogas is defeated Go out to thermal power plant boiler carry out combustion power generation when, but pressure when being transported to due to biogas boiler combustion still has 1-1.5kpa, and Operation is generally negative pressure operation in boiler, is thus easy to cause biogas to be tempered, can be caused if being tempered in air accumulator Equipment safety and the life security of personnel.
Utility model content
The utility model proposes a kind of marsh gas power generation air inlet protection device, solve and be delivered to boiler combustion in the prior art When, the defects of delivery safety hidden danger be present.
What the technical solution of the utility model was realized in:
A kind of marsh gas power generation air inlet protection device, including water sealed tank and positive/negative pressure protection device, water sealed tank are protected with positive/negative-pressure Protection unit connects, and the water sealed tank is internally provided with dividing plate, water sealed tank is divided into upper chamber and lower chambers, bottom chamber is equipped with liquid Body, gas outlet, in addition to air inlet pipe and escape pipe is provided with the dividing plate, the air inlet pipe is connected to bottom chamber, described Escape pipe is connected with boiler oil import, and the positive/negative pressure protection device includes hermetically sealed can, and water is additionally provided with the hermetically sealed can Tube sealing, blast pipe, water inlet pipe and drainpipe, described blast pipe one end connect water sealed tank, and the other end connects with hermetically sealed can, the water Tube sealing extends to the bottom of liquid level.
Further, the side wall of hermetically sealed can is provided with level sensor.
Further, the hermetically sealed can is also connected with biogas temporary storage tank.
Further, it is additionally provided with nitrogen purge system on the hermetically sealed can.
Further, the gas outlet, which is provided with, considers water cover, prevents aqueous vapor from entering in boiler oil import.
In summary, the utility model has the advantage of:Combustion gas input port and fuel gas buring mouth are completely cut off by water sealed tank, It will not also be burnt even if tempering, ensure that equipment and the safety of personnel, meanwhile, positive/negative pressure protection device is set, prevents water sealed tank Positive/negative-pressure phenomenon is formed, equipment and personnel are damaged.
