Abstract
The utility model discloses an energy-saving heating furnace with double energy sources. The energy-saving heating furnace comprises a preheating circular furnace and a combustion chamber. Electric heating wires are mounted on the inner walls of two sides of the preheating circular furnace, a flue is mounted at the inner bottom of the preheating circular furnace, and tail gas which is generated when natural gas is combusted can be filed into the preheating circular furnace via the flue. The energy-saving heating furnace has the advantages that the energy-saving heating furnace is provided with the electric heating wires and the flue, accordingly, products in the preheating circular furnace can be heated in a heat radiation mode and a heat conduction mode, the internal temperature of the preheating circular furnace can be rapidly increased, heat can be uniformly distributed in the circular furnace, the temperatures of the products can be quickly increased, and internal and external temperature difference of the products can be lowered; the high-heat tail gas which is generated when the natural gas is combusted can be recycled, accordingly, the utilization rate of the natural gas can be increased, and energy source consumption can be reduced; the dependency on the natural gas in temperature rise procedures can be greatly reduced owing to the effects of the electric heating wires, and natural gas consumption can be effectively reduced; the energy-saving heating furnace with the double energy sources is particularly applicable to impregnation procedures of carbon products.
Description
Technical field
The utility model relates to the kiln that a kind of industrial production is used, and relates in particular to a kind of Dual-energy source energy-saving heating furnace.
Background technology
At present, the kiln using in industrial production, mainly contains two kinds of mode of heatings, and a kind of is to rely on the hot heating product of fuel combustion, and this kiln is called for short gas furnace, and another kind is to rely on resistance heating heating product, and this kiln is called for short electric furnace.Because needs are avoided heat loss, electric furnace often has good sealing property, and this makes its internal gas circulation few, and in stove, thermal field is inhomogeneous, and products temperature difference is obvious.The heat transfer process of gas furnace, is mainly that hot-air transfers heat to goods by conduction pattern, plays the effect of heating product.For part particular product as for carbon product, relation due to its structure and raw material, its heat transfer speed is very slow, so no matter adopt electric furnace or gas furnace, all exist goods internal-external temperature difference larger,, simultaneously because thermal source is single, also there is the problem that preheating time is long, waste energy in the problem that the heat time is long.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem the uniform Dual-energy source energy-saving heating furnace of goods internal and external temperature in a kind of stove.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A Dual-energy source energy-saving heating furnace, comprises preheating flue and combustion chamber, on the both sides inwall of described preheating flue, heating wire is installed, and the bottom in described preheating flue is provided with for passing into the flue of combustion of natural gas tail gas.
On the inwall of the both sides of preheating flue, heating wire is installed, is utilized heat radiation mode to heat the goods in preheating flue; Meanwhile, the bottom in preheating flue passes into the high hot exhaust gas that in combustion chamber, combustion of natural gas produces, and with conduction pattern heating product, and the gas in preheating flue is played to agitaion, improves the uniformity of thermal field in preheating flue.
Preferably, described in multistage, heating wire is uniformly distributed and is covered with the both sides inwall of described preheating flue.
It is horizontal that described heating wire is.
The beneficial effects of the utility model are:
The utility model is by arranging heating wire and flue, goods in preheating flue are carried out to two kinds of modes of heat radiation and heat conduction and heat, the temperature in preheating flue is raise rapidly, and heat is uniformly distributed in flue, can improve rapidly the temperature of goods, and reduce the inside and outside temperature difference of goods.Because the high hot exhaust gas that combustion of natural gas is produced recycles, improve the utilization rate of natural gas, reduced energy resource consumption; Meanwhile, radiation mode is better than conduction pattern to the heating effect of carbon product, at goods two ends, adopts after electric-heating-wire-heating, can effectively improve goods programming rate; Due to the effect of heating wire, the dependence to natural gas in temperature-rise period reduces greatly, has effectively reduced natural gas consumption; In addition, can also be in stove appropriate location diversion fan is installed, by change rotation speed of fan and towards, change furnace gas and flow to and flow velocity, make the Shi Yineng that changes of goods placement situation in stove obtain the thermal field of stable and uniform; This Dual-energy source energy-saving heating furnace is particularly useful for carbon product impregnating operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of Dual-energy source energy-saving heating furnace described in the utility model, there is shown internal structure.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, Dual-energy source energy-saving heating furnace described in the utility model comprises preheating flue 2 and combustion chamber 1, on the both sides inwall of preheating flue 2, heating wire 3 is installed, bottom in preheating flue 2 is provided with for passing into the flue 4 of combustion of natural gas tail gas, and multistage institute heating wire 3 is horizontally and is uniformly distributed and is covered with the both sides inwall of preheating flue 2.The high hot exhaust gas outlet of the entrance of flue 4 and combustion chamber 1 is connected, heating wire external power supply, and these are all conventional structures, do not repeat them here.
During application, the Carbon Materials roasting base of needs heating is packed in preheating flue 2, close fire door sealing.Start heated by natural gas system, improve fast the temperature in preheating furnace courage 2, and preheating heating wire 3.Connect after heating wire 3 power supplys, utilize radiation mode to continue heating product, and the high-temperature tail gas in combustion chamber 1 is introduced in flue 4, its heat is diffused in preheating flue 2 with conduction pattern (being convection current), and agitation air makes the temperature in whole preheating flue 2 even.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; so long as the technical scheme that can realize on the basis of above-described embodiment without creative work all should be considered as falling within the scope of the rights protection of the utility model patent.
