Abstract
The utility model provides an electric heater for natural gas, comprising a heater body, an upper flange matched with the heater body, an upper heater cover connected with the upper flange, a top heater cover connected with the upper heater cover, a skirt seat arranged on the lower part of the heater body, an electric heating element extended into the heater body and connected with the upper heater cover and/ or the top heater cover by a sealing pair, an explosion-proof terminal box connected with the top heater cover and an air exchanging pipe connected with the bottom of the heater body. The utility model uses the electric heating element to directly heat the natural gas passing through the inner part of the electric heater, eliminates naked fire and is favorable for regulating and controlling the temperature of the heater, being suitable for using as the heater for the natural gas in oil and gas fields, gas purifying factories, etc.
Description
The utility model relates to a kind of heating furnace, particularly relates to a kind of natural gas electric furnace.
Existing gas heating furnace is generally two kinds of forms, and the water batch heater that the first adopts on oil gas field heats natural gas, promptly adds hot water with natural gas, heats natural gas again with the hot water after being heated again.It two is in Gas Purification Factory, and the fire tube heater that adopts in the natural gas chemical plant heats natural gas, and promptly natural gas burns in that pipe is outer, and heated natural gas flows through in managing.All unavoidably there is naked light in this two class A furnace A in inflammable, explosive occasion, has proposed requirements at the higher level to fire safety.In addition, the adjustment of this two class A furnace As, especially water batch heater and control are very difficult.
The purpose of this utility model is to provide a kind of heating is set directly in the stove, promptly places the natural gas electric furnace of gas medium.
The utility model natural gas electric furnace is to realize like this, it comprises brings tracheae and escape pipe into, and the body of heater of forming by furnace shell, inner core and thermal insulation layer, with the upper flange that the body of heater upper end cooperates, the stove top case that is connected with upper flange, the furnace top cover that is connected with stove top case, be arranged on the skirt of body of heater bottom, the heating that stretches in the stove and be connected with stove top case and/or furnace top cover by sealing pair, the anti-explosion terminal box that is connected with furnace top cover, and the scavenge trunk that is connected with bottom of furnace body.Wherein stove top case and upper flange all adopt bolt to be connected between furnace top cover and the stove top case, anti-explosion terminal box and furnace top cover.Anti-explosion terminal box is a hermetically-sealed construction, prevents that air from entering in the box, and fills up heat-resistant insulation material in the box, promptly is that natural gas spills from sealing pair and enters in the box in the stove, because no oxygen can not set off an explosion yet.For reducing heat, can insulation cover be set at the inner core top from the loss of furnace roof portion.Heating generally is made up of heater and binding post, and heater is advisable with spiral heat-generating pipe, can improve its thermal efficiency.The effect of sealing pair is that inflammable, explosive natural gas is enclosed in the stove.
The modes of emplacement of the heating of the utility model natural gas electric furnace and sealing pair can have three kinds of forms of implementation.The first places in the stove when the heater of heating, and when binding post placed in the anti-explosion terminal box, the sealing pair of employing soldered form was connected between heating and stove top case and furnace top cover; It two is that heater when heating places in the stove, when binding post places in the armored cassette, also can adopt the sealing pair of super gasket form to be connected between heating and stove top case; It three is when the heater of heating and binding post all place in the stove, adopts the sealing pair of withstand voltage high temperature insulation stuffing-box form to be connected between heating and furnace top cover, and the lead-in wire of binding post draws outside the stove by sealing pair, enters in the anti-explosion terminal box.
Before using, the utility model natural gas electric furnace earlier nitrogen is fed in the stove from scavenge trunk, air in displacement is come out of the stove, and from the escape pipe discharge, after furnace air concentration is less than 5%, again natural gas is fed in the stove from air inlet, discharged from the gas outlet by heating heating back.
The advantage of the utility model natural gas electric furnace is that heating places gas medium, thermal efficiency height, and the adjustment control performance is good, easy to operate, safe and reliable, long service life is applicable to that oil, gas field and gas purification factory, natural gas chemical plant etc. make gas heating furnace.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
Fig. 1: the utility model structural representation
Fig. 2: the sealing pair of soldered form connects
Fig. 3: the sealing pair of super gasket form connects
Fig. 4: the sealing pair of heat-resisting withstand voltage insulating packing letter form connects.
The utility model natural gas electric furnace comprises and has air inlet pipe 1 and escape pipe 2, and by furnace shell 3, the body of heater that inner core 4 and thermal insulation layer 5 are formed, the upper flange 7 that cooperates with the body of heater upper end, the stove top case 8 that is connected with upper flange 7, the furnace top cover 9 that is connected with stove top case 8, the anti-explosion terminal box 10 that is connected with furnace top cover 9, be arranged on the skirt 6 of body of heater bottom, the scavenge trunk 11 that is connected with bottom of furnace body, stretch into the heating that constitutes by heater 13 and binding post 12 in the body of heater, heating is connected with stove top case 8 and/or furnace top cover 9 by sealing pair, and the insulation cover 14 that is arranged on the inner core top.Wherein sealing pair can be a soldered 15, super gasket 16 or heat-resisting withstand voltage insulating packing letter 17.
Claims (4)
1, a kind of natural gas electric furnace, comprise and bring tracheae and escape pipe into, and the body of heater of being made up of furnace shell, inner core and thermal insulation layer is with the upper flange that the body of heater upper end cooperates, the stove top case that is connected with upper flange, the furnace top cover that is connected with stove top case, and the skirt that is arranged on the body of heater bottom, it is characterized in that heating stretches in the body of heater, and be connected with stove top case and/or furnace top cover by sealing pair, be connected with anti-explosion terminal box on the furnace top cover, bottom of furnace body is connected with scavenge trunk.
2, natural gas electric furnace as claimed in claim 1 is characterized in that sealing pair is a soldered.
