Abstract
The utility model relates to a special heating device for an oil and natural gas field, in particular to a vacuum phase-change heating furnace with a furnace body capable of still normally running under negative pressure or micro-positive pressure. The vacuum phase-change heating furnace comprises a furnace body in which a heat exchanger, a burning device and a fuel preheating device are arranged, wherein the heat exchanger comprises heating coil pipes, and the both ends of the heating coil pipes extend out of the furnace body; the burning device comprises a combustion chamber, a smoke pipe and a smoke box, wherein the combustion chamber, the smoke pipe and the smoke box are connected end to end, and the end parts of the combustion chamber and the smoke box extend out of the furnace body; the fuel preheating device comprises preheating tubes arranged in the furnace body, and both ends of the preheating tubes extend out of the furnace body. The utility model has the advantages that water is not required to be supplied often, the water quality in the furnace is relatively stable, and the frequent blowdown is not required; mineral matters cannot be carried in the furnace along with water to cause the phenomena of scale formation, excessive sintering, humping, and the like; and the utility model has high thermal efficiency and long service life.
Description
Technical field
The utility model is the special-purpose firing equipment of a kind of oil gas field, the vacuum phase transition heating furnace that particularly a kind of body of heater still can normally move under negative pressure or pressure-fired.
Background technology
Along with the continuous exploitation in oil field, ton oil consumption tolerance also can go up significantly, and incomplete fuel of fuel that is caused by heating furnace and the waste of radiation loss equal energy source and environmental pollution have become the problem that full oil field can not be ignored, therefore must strengthen the dynamics of saving energy and reduce the cost.Applying of vacuum furnace and technology thereof solved this difficult problem effectively, and advantages such as this stove is low with its cost, energy consumption is low, efficient is high, automaticity height have become the desirable regeneration product of present oil field traditional heating stove.When but existing vacuum furnace moved under negative pressure or pressure-fired, impurity can be brought phenomenons such as fouling, burning, bulge take place in the stove into water, carried out blowdown so need often to change stove water, had reduced operating efficiency.
Summary of the invention
The purpose of this utility model is in order to overcome the defective of existing vacuum furnace generation fouling, burning, bulge, invent a kind of heat(ing) coil that in heating furnace, is provided with, in airtight body of heater, carry out the vacuum phase transition heating furnace of phase-change heat-exchange by working-medium water in the stove and the heated medium in the coil pipe.
The purpose of this utility model realizes as follows: described vacuum phase transition heating furnace comprises a body of heater, be provided with heat-exchanger rig, burner and fuel preheating device in the body of heater, heat-exchanger rig is made of heat(ing) coil, and the outside at body of heater is stretched out at the two ends of heat(ing) coil; Burner is made up of combustion chamber, smoke pipe and smoke box, and combustion chamber, smoke pipe and smoke box join end to end, and the outside at body of heater is stretched out in the end of its combustion chamber and smoke box; Fuel preheating device is made up of the economizer bank of being located in the body of heater, and the outside at body of heater is stretched out at the two ends of economizer bank.
Described body of heater is provided with riot gear.
Described body of heater is provided with inspection socket.
Described body of heater is provided with liquid level and shows mouth.
Described body of heater is provided with connecting hole and hanger.
Described body of heater is provided with fuel preheating device.
Be provided with bracing or strutting arrangement below the described body of heater.
Good effect of the present utility model is as follows: because utility model is to work in airtight environment, heat carrier water recycles, and dailyly need not moisturizing, only need stove water of replacing in a year to get final product, just because of few moisturizing, so water quality is relatively stable in the stove, also often blowdown; Because body of heater is to work under anaerobic state, so mineral matter can not bring phenomenons such as fouling, burning, bulge take place in the stove into water yet, body of heater moved under negative pressure or pressure-fired can not produce oxygen corrosion yet, and security performance is good; The utility model efficiency of heating surface height, long service life; The utility model is fuel with the oil and gas, is equipped with advanced fully automatic burner, and is sturdy and durable, automaticity height, good reliability.
