In the present invention, describedly open when being 0.018Mpa～0.022Mpa at atmospheric pressure value, atmospheric pressure value is 0.043Mpa～the gas pressure control switch of closing during 0.047Mpa, be that working pressure air pressure lower control limit value is that working pressure air pressure upper control limits value is the gas pressure control switch of 0.043Mpa～0.047Mpa in 0.018Mpa～0.022Mpa, the tank body in the tank body, that is to say when operating air pressure value in the tank body is 0.017Mpa～0.022Mpa the gas pressure control switch of opening, closing when the operating air pressure value is 0.043Mpa～0.048Mpa in the tank body.Facts have proved that during the gas pressure control switch of working pressure control range at 0.02Mpa～0.045Mpa, described gasifying tank output fuel is safer and effective in adopting tank body.The gas pressure control switch of control range at 0.02Mpa～0.045Mpa adopted in special recommendation of the present invention.Described gas pressure control switch can be the commercially available gas pressure control switch that has the air pressure inductive probe, also can be the gas pressure control switch of independently making at the tank body specific (special) requirements in case of necessity.Described gas pressure control switch is controlled at 0.018Mpa～0.022Mpa, upper limit air pressure with lower limit air pressure in the tank body and is controlled at (upper and lower limit air pressure is slightly different according to the difference of employed gas pressure control switch) between 0.043Mpa～0.047, thereby make the existing relatively gasifying tank tank body internal pressure of tank body internal pressure lower, normally export under the prerequisite of inflammable gas and liquid fuel satisfying gasifying tank, increase the Security of gasifying tank.The gas pressure control switch of described independent setting can allow tank body design and make more flexible and changeablely, and layout more becomes rationally, and preparation process is easier, helps later maintenance and maintenance.The control switch air pressure inductive probe of described gas pressure control switch can be the electronic type inductive probe, also can be the mechanical type inductive probe.
In the present invention, because described gasifying tank has pneumatic tube and transport pipe, and a jar internal pressure is higher than atmosphere outside pressure, the volatile gas of splendid attire just can outwards be exported along pneumatic tube in the gasifying tank, the not volatile liquid fuel of splendid attire just can outwards be exported at the driving lower edge of jar internal pressure transport pipe in the gasifying tank, and the means of the corresponding user's of making selective combustion effect become more flexible:
If 1 inflammable gas abundance, can satisfy the calorific value that the output burning produces, just only inflammable gas need be exported as comburant, promptly be closed transport pipe in working order the time and only open pneumatic tube, allow inflammable gas export outside burner to as unique comburant.
2, inflammable gas is inadequate in jar, promptly can not satisfy the calorific value that output burning produces, and the user just can open transport pipe when needing combustion heat value higher, allows not volatile liquid fuel export the outside to through transport pipe and burns.At this moment, pneumatic tube and transport pipe all are in opening state, and inflammable gas and liquid fuel supply to the external-burning source simultaneously through pneumatic tube and transport pipe respectively and carry out mixed combustion.In actual use, can be this device outfit liquid, gas fuel mix device separately, but also can directly use the burner that has liquid, gas fuel mix device.
3, both made under the situation of inflammable gas abundance, also still can open pneumatic tube and transport pipe simultaneously, allow inflammable gas and liquid fuel supply to the external-burning source simultaneously through pneumatic tube and transport pipe respectively and carry out mixed combustion, allow the user use higher calorific value.
4, because can be with not volatile liquid fuel in the jar through transport pipe output burning, so the residue in the tank body also can be as not volatile liquid fuel output and burning separately.Like this, just can not stay residue in the gasifying tank, correspondingly can allow the interior fuel of gasifying tank fully export burning, effectively utilize the energy, saved cost.
In addition, this device has also brought non-obvious advantage, promptly can be directly in jar the liquid fuel of not volatile liquid fuel of splendid attire or gasification result difference export the burning of external-burning source to.For example: a lot of liquid oiliness by-product that produces during present petrochemical industry production and gas chemical industry produce (the by-product---tops that petrochemical industry produces in producing, or by-product--the liquid oiliness by-product of-condensate or the like that produces in gas chemical industry's production), these liquid oiliness by-products seldom produce maybe and can not produce volatilizable gas, can not be as the fuel of existing gasifying tank, this liquid state oiliness by-product not only is not utilized, processing cost is quite high again, even also causes environmental pollution when handling.When adopting gasification tank of multifunction high effect energy saving liquid fuel of the present invention, just these liquid oiliness by-products can be contained in the tank body and directly export the burning of external-burning source to through transport pipe as fuel (liquid incendivity thing).Allow original discarded liquid incendivity thing turn waste into wealth, both solved the energy starved problem, help environmental protection again.
