Description

Phase transformation fuel-firing gas-firing vacuum furnace

(1) technical field

The utility model relates to a kind of improvement that crude oil, natural gas and oil-polluted water pipeline are carried heating furnace structures such as heating, the heating of oil well water, heating, domestic water heating that is used for, adopting phase transformation vacuum heat transfer technology, is a kind of phase transformation fuel-firing gas-firing vacuum furnace specifically.

(2) background technology

In oil field, gas field oil recovery, gas production and oil-gas gathering and transportation process, crude oil, natural gas, oil well water need heating, and crude oil, natural gas line are carried also needs heating.Existing heating furnace adopts circular fiery core structure, and shortcoming is that water capacity is big, and it is slow to heat up, and needs the long period just can be heated to needed temperature, and the thermal efficiency is on the low side, wastes energy.

(3) summary of the invention

The utility model purpose is to overcome the shortcoming in the above-mentioned technology, a kind of phase transformation fuel-firing gas-firing vacuum furnace is proposed, be used for crude oil, natural gas and oil-polluted water pipeline and carry heating such as heating, the heating of oil well water, heating and domestic water, water capacity is reduced, improve programming rate, improve the thermal efficiency.

The utility model purpose is realized by following technical scheme: this phase transformation fuel-firing gas-firing vacuum furnace, support by bearing 1, be surrounded by outside on the shell 8 of heat-insulation layer and be connected with exhaust-valve 6, vacuum valve 7, water intaking valve 12, explosion proof door 10, water level meter 13, blowoff valve 14, and all be communicated with shell 8 inner chambers, it is characterized in that shell inner chamber bottom is provided with ripple courage combustion chamber 2, ripple courage combustion chamber is anterior to be connected with full automatic combustion engine 3, and the rear portion is connected with threaded flue 11 by the chamber 15 of strile-bacing, threaded flue connects chimney 5 by smoke interface 4, ripple courage combustion chamber and threaded flue are formed heating system, and its upper space forms the carbonated drink chamber, and heat exchange coil 9 is housed in the carbonated drink chamber.

Heat exchange coil 9 is a branch of coil pipes, perhaps two bundle coil pipe, perhaps three beams coil pipes.

Ripple courage combustion chamber 2 latter ends of first backhaul connect the chamber 15 of strile-bacing, and again by the chamber 15 connecting thread smoke pipes 11 that strile-back, connect chimney 5 by front smoke box 16, smoke interface 4, form second backhaul; Perhaps draw threaded flue and be connected, form exhaust gases passes once more, promptly form the 3rd backhaul, connect chimney 5 by smoke interface 4 from the back smoke box with back smoke box 17 by front smoke box 16.

Heat exchange coil is selected a branch of heat exchange coil according to the needs that use, perhaps two bundle heat exchange coil, perhaps three beams heat exchange coils.When phase transformation fuel-firing gas-firing vacuum furnace only is used for heating in crude oil, perhaps only be used for adding the hot oil wells water, when perhaps only being used for heating, as long as a branch of heat exchange coil; When phase transformation fuel-firing gas-firing vacuum furnace is used for heating respectively two kinds of different media, for example be used for heating in crude oil and oil well water simultaneously, just adopt two bundle heat exchange coils, one group of coil pipe is oily heat exchange coil, another group heat exchange coil is the water heat exchange coil; If domestic water upward also is provided warming oneself or providing simultaneously through this basis, just increases hot water or the domestic water that a branch of heat exchange coil is used for heating supply heating installation again.

A large amount of heats by flame and high-temperature flue gas band after the combustor burning, through ripple courage combustion chamber 2 and threaded flue 11, the water in the heat transferred carbonated drink chamber, after the water in the carbonated drink chamber absorbs enough heats, produce vaporization and form low-pressure steam, low-pressure steam carries heat and rises, and carries out heat exchange with heated medium in the heat exchange coil on top, thus the heating process of finishing.

The utility model advantage is rational in infrastructure, adopts phase transformation vacuum heat transfer technology, thermal efficiency height; Heating agent adopts deoxygenated water in the stove, and no incrustation scale does not have corrosion, and long service life can not advanced in boiler operatiopn simultaneously, does not increase not subtract; Adopt technological means to make it to produce and keep vacuum in the stove, no explosion danger, security is good, and shell adopts circular cross-section, and water capacity is little, thereby programming rate is fast, can satisfy the needs of operating mode in the short time.
