Abstract
The invention relates to a novel trolley-type dual-purpose furnace for carrying out decontamination heating and drawing temper on an oil pipe, which comprises a furnace body steel structure, a furnace door, a furnace door lifting mechanism, a trolley, a trolley travelling device, a furnace lining, a gas pipeline, a control system of the gas pipeline, an air pipeline, a control system of the air pipeline, a draught fan, a smoke discharge pipeline, a primary waste heat recovery system, a secondary waste heat recovery system, a spray purification system, a temperature controlling and recording system, and an operation and control system for an upper computer and a lower computer. When the oil contamination of a steel pipe is treated, and the furnace temperature reaches to 650-670 DEG C, the grease and the contamination are not fully burnt, so that a secondary combustion chamber is arranged at the part of a smoke discharge hole; when the temperature of the secondary combustion chamber reaches to 900-1000 DEG C, the oil smoke is continuously burnt in the secondary combustion chamber, and most combustible ingredients are fully burnt, so that the impurities and the harmful gas in the smoke can be reduced. The smoke discharge pipeline of the secondary combustion chamber is provided with an air preheater, and the cold air generated by the fan is heated to be hot air, so that the utilization rate of natural gas is improved by the combustion-supporting hot air during combustion. A water heat exchanger is added behind the air preheater, the cold water in a discharge pipe is heated to be hot water, and the heated hot water can be used as domestic water.
Description
Technical field
The present invention relates to the corollary equipment of petroleum machinery processing industry, a kind of car-type oil pipe decontamination heating and temper stove.
Technical background
In the oil exploitation industry, use pipeline road in a large number, in long-term the use; A large amount of greasy dirts regularly will be cleared up attached on the steel pipe, and way in the past is in conventional oven, steel pipe to be carried out burn processing; Because burning is insufficient, produces a large amount of oil smoke gas, and environment is caused great pollution; Simultaneously also can be on flue and heat exchanger deposit dirt, cause smoke evacuation not smooth.A kind of novel environment protection type gas dual-purpose stove that has secondary combustion chamber and flue gas is sprayed in force; For further improving rate of energy; At the air preheater rear portion water-to-water heat exchanger is set, through the tube bank of heat exchanger, the heating of the cold water of circulation; The water of heating can be used for domestic water, saves the energy effectively.
The requirement of relevant specification, standard is satisfied in design, manufacturing, check and the examination of decontamination heating of this car-type oil pipe and temper dual-purpose stove.Zero, the parts of this stove select for use quality material to make; The temperature-controlled precision that guarantees complete equipment is high; Heating and heat treatment high efficiency, fuel consumption is low, and noise and discharge of harmful gases index that the equipment operation produces are lower than national standard; The durable degree of this dual-purpose stove is higher than the durable level of the domestic equal type of furnace, and this stove is made superior, practical, safe, reliable.
Decontamination heating of this car-type oil pipe and temper dual-purpose stove structure are formed and are comprised: furnace binding, fire door and fire door hoisting mechanism, furnace lining, car and trolley running device, fuel gas pipeline and control system, air pipe line and control system, smoke evacuation and residual neat recovering system, water heating system, spray equipment, temperature control and register system, host computer and compositions such as slave computer operation and control system.

Summary of the invention
A kind of car-type oil pipe decontamination heating and temper stove can further improve rate of energy, and the flue gas of being discharged does not pollute environment.Steel pipe is in the process of handling greasy dirt; Furnace temperature reaches 650-670 ℃, and grease and dirt be fully burning not, therefore at smoke evacuation outlet position a secondary combustion chamber is set; The second-time burning room temperature reaches 900-1000 ℃; Oil smoke burns away at this, and most flammable compositions are fully burned, and has reduced impurity and the pernicious gas in the flue gas.On secondary combustion chamber smoke evacuation pipeline, air preheater is set, the utilization rate of natural gas when combustion-supporting hot blast has improved burning.Behind air preheater, increase a water-to-water heat exchanger, be used for domestic water to the water of heating.Back at water-to-water heat exchanger is provided with spray eliminator, and the impurity in the flue is discharged to the pure flue gas of low temperature in the atmosphere through air-introduced machine then.When the tempering furnace, second heating chamber need not work, and to make principle the same with the common heat treatment furnaceman.

The specific embodiment
As shown in Figure 1, workpiece is placed on the special bin, by chassis it is written in the stove, closes fire door; The igniting heated parts, second heating chamber's this moment combustion preheater is along with the rising of furnace temperature; Greasy dirt on the steel pipe takes fire, and produces a large amount of soot gas, arrives second heating chamber through the smoke evacuation pipeline; Carry out high temperature and fully burn, the residue in the flue gas has converted heat and small particle to, and high-temperature flue gas passes through air preheater; Heat cold wind, hot blast has improved the thermal efficiency of stove through pipeline and natural gas mixed combustion.Flue gas passes through water-to-water heat exchanger once more, and the cold water heating of flowing through in the comb, the hot water of generation can be used for domestic water, and the heat of flue gas obtains utilizing for the second time.The flue gas of having lowered the temperature passes through spray eliminator once more; The dust in flue gas particle combines to be deposited in the sump with water; Flue gas has obtained final purification, under the state of low temperature, is discharged in the atmosphere, and flue gas after being purified has no pollution to environment; Heat energy is fully utilized, and makes whole equipment not only energy-conservation but also improved service life.
The operation principle and the version of the invention of above-described car-type combustion gas heat treatment environment-friendly stove, all employings be equal to or the similar techniques scheme all within scope of patent protection of the present invention.
