Abstract
The utility model relates to a low-pressure high-temperature heat-conducting oil-fired furnace. The utility model is composed of a hearth, a furnace housing, a furnace body and a chimney. The interior of the furnace housing 1 is provided with a refractory material layer 2 forming the furnace body, and the interior of the furnace body of the upper space of the hearth is provided with a coil pipe 3. A coil pipe 2 forms the furnace body, and the interior of the furnace body of the upper space of the hearth is provided with the coil pipe 3. Both ends of the coil pipe 3 form an oil inlet 4 and an oil outlet 5 by a furnace housing body, and the coil pipe 3 is supported on the furnace housing 1. The upper part of the coil pipe 3 is provided with a fire baffling top cover. The oil is used as the working medium. The utility model has the advantages of high oil temperature, circulating oil use, little loss, light weight, simple structure, small occupation area, low investment and energy saving.
Description
The utility model is relevant with vertical heater, and is especially relevant with a kind of low-voltage high-temperature heat-conducting oil furnace.
Existing vertical heater for example utilizes the steam boiler of steam as heat-conducting medium, because steam pressure and vapo(u)rous temperature relation in direct ratio will obtain the higher saturated vapor of temperature, its operating pressure is very high.The saturated-steam temperature that as operating pressure is the steam boiler of 1.3MPa is 194 ℃, and the saturated-steam temperature that will make boiler is 320 ℃, the operating pressure of boiler just must reach 11.3MPa, even technically can make operating pressure and the high like this steam boiler of temperature, its investment is very high, and boiler work operation also is unsafe.
The purpose of this utility model provides a kind of simple in structure, small investment, and operating pressure is low and low-voltage high-temperature heat-conducting oil furnace that operating temperature is high.
The utility model is achieved in that
The utility model is made of body of heater and chimney, it is characterized in that furnace shell 1 and its interior refractory masses 2 constitute bodies of heater, and coil pipe 3 is arranged in the body of heater in the burner hearth sky, and the two ends of coil pipe 3 constitute oil-in 4 by furnace shell and by hydraulic fluid port 5, coil pipe 3 is supported on the furnace shell 1.
Coil pipe 3 of the present utility model is made of left-handed coil pipe 6 and the dextrorotation coil pipe 7 that is positioned at it, left and right capstan pipe is gapped but communicate, oil-in 4 is in dextrorotation coil pipe lower end, oil-out is in left-handed coil pipe lower end, support card (8) is arranged between two coil pipes, coil pipe spacer block 9 is arranged between coil pipe, and coil pipe 6 is supported on the body of heater by fixed support 11.There is the fiery top cover 10 of retaining the coil pipe upper end, and top cover 10 is supported on the body of heater.
Furnace shell 1 of the present utility model is formed by connecting by flange by shell 12 and shell end socket 13.Shell 12 bottoms are lined with furnace wall 14, and coil pipe is supported on the furnace wall 14.
The utility model is working media with the conduction oil, and its distillation point can be up to 343 ℃, thereby outlet oil temperature of the present utility model exceeds more than 1 times than the specified outlet steam temperature of existing steam boiler and operating pressure is identical.
Spiral about heat conduction coil pipe of the present utility model is inside and outside, structure is very compact and heat exchange path working media is very long, the heat exchange efficiency height, and working media can be recycled, and loss is little, and power consumption is few, and energy-saving effect is remarkable.
The utility model is simple in structure, and floor space is little, light weight, and reduced investment, safety, energy-conservation, can be widely used as food, medicine, the oven dry of industries such as chemical industry and the thermal source of firing equipment.
Following is accompanying drawing of the present utility model:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 1.
Following is embodiment of the present utility model:
Furnace shell 1 is formed by connecting by connecting bolt 16 by adpting flange 15 by shell 12 and shell end socket 13.Stove pin 17 is arranged at the bottom of shell 12.Burner hearth backing ring 18 and backing ring support 19 and are welded on the shell.Be lined with furnace wall 14 on the backing ring 18 and constitute burner hearth.Grate 20 and stove gate device 21 are arranged.Ash door 26 is arranged under the grate.
