Description
One, technical field
The utility model relates to the used inner rib tubular type water batch heater of a kind of petroleum and petrochemical industry.
Two, background technology
Water batch heater is a widely used equipment in petroleum and petrochemical industry production of hydrocarbons and the conveying, in the horizontal metal circular cylindrical shell, be provided with fire tube, smoke pipe and heat(ing) coil, gas or liquid fuel are by burning in the fire tube of burner in body of heater, in the heat(ing) coil of heated medium in housing, by the medium in the middle heat-carrying agent heat(ing) coil, and middle heat-carrying agent is by the directly heating of fire tube.
The fire tube of tradition water batch heater becomes the U-shaped structure with smoke pipe, is arranged in the housing middle part, and fuel burns in the fire tube, the high-temperature flue gas parallel baffled smoke pipe of formation, and heat-transfer effect is poor, and the thermal efficiency is low, and body of heater volume and metal consumption are big, and space availability ratio is not high.This mode is suitable for for the less water batch heater of thermic load, but large-scale heating furnace with this mode then have the exhaust gas temperature height, the thermal efficiency is low, metal wastage is big, play disadvantages such as the stove time is long.Along with the later development in oil field, the heating furnace of requirement load is increasing.Therefore, need to develop a kind of efficient heating stove,, reach the purpose that reduces water jacket furnace cost and energy efficient to improve heater efficiency, to reduce a metal consumption and a stove time.
Three, summary of the invention
In order to reduce exhaust gas temperature, improve thermal efficiency of heating furnace to reduce the oil gas fuel consumption, reduce the equipment metal consumption, reduce equipment manufacturing cost, invent a kind of inner rib tubular type water batch heater.
The utility model is made up of horizontal cylindrical shell, fire tube, inner rib tubular type smoke pipe, smoke box, chimney, heat(ing) coil, burner and control system.It is characterized in that heat(ing) coil is arranged on the middle and upper part in the housing, the fire tube is arranged on the interior middle and lower part of housing with the inner rib tubular type smoke pipe, and the inner rib tubular type smoke pipe is arranged on the side of enclosing of fire tube, and the one end is communicated with the fire tube, and the other end is communicated with the smoke box that is arranged on the chimney bottom.Smoke box is designed to semicircle, and chimney is vertically fixed on semi-circular top and is communicated with, and the madial wall of inner rib tubular type smoke pipe and smoke box is vertical to be welded and be communicated with, and the curved bottom of smoke box is buckled on the burner; Be provided with in week in the inner rib tubular type smoke pipe and arrange orderly pin rib or fish scale rib and groove.At fiery cylinder roasting, the flame of formation and high-temperature flue gas enter smoke box and chimney and discharge after carrying out heat exchange by fire tube and heat-carrying agents such as inner rib tubular type smoke pipe and water respectively by burner for gas or liquid fuel; Vaporization after heat-carrying agents such as the interior water of housing are heated forms high-temperature steam, the interior mobile former wet goods heated medium of heat(ing) coil, and high-temperature steam returns the interior middle and lower part of housing after condensing into liquid on the coil pipe outer wall, again with fire tube and smoke pipe heat exchange.The utility model with internally finned tube as smoke tube, increased heat convection area and convection transfer rate, the coefficient of heat transfer 2-5 that improves fume side doubly, thereby improve the smoke pipe heat transfer coefficient, make less heat transfer area obtain more heat output, thereby reduce the flue gas exhaust gas temperature, improve heater efficiency, compare with conventional water jacket furnace, compact conformation, metal wastage reduces about 50%, and heat-transfer effect is good, and the thermal efficiency reaches about 90%.
In order to raise the efficiency, the utility model is furnished with control system, and control system has functions such as burner is controlled automatically, the automatic control of heating-up temperature.
The utility model has been compared following advantage with traditional indirect heater:
1. use internally finned tube as smoke pipe, strengthened the perturbation action of flow of flue gas, and increased heat transfer area, make the convective heat-transfer coefficient of smoke pipe fume side improve 2-5 doubly, thereby increased the ratio of smoke pipe heat exchange, and made exhaust gas temperature reduce significantly, improved the efficient of heating furnace.
2. the inner rib tubular type smoke pipe directly is arranged in all sides of fire tube, and fire tube and smoke pipe are arranged in the bottom of cylindrical shell, has improved the utilization rate of the device space, has reduced the size of equipment, thus the saving steel.
3. adopt internally finned tube as smoke pipe, flow of flue gas is had strong perturbation action, have very strong deashing ability.
