Abstract
The utility model relates to an energy saving net type radiating element of industrial kiln, comprising a plurality of single layer net body stacking together. The utility model is arranged at the rear part of a heating space in the kiln, with a radiation interchange, the flue gas temperature can be reduced, and the temperature field in the kiln can be uniformly distributed. Therefore, the utility model has remarkable energy saving effect.
Description
A kind of industrial furnace heating space energy saver.
Be the device that uses of purpose such as heat exchanger etc. with energy-conservation, on industrial furnace, use more and more widely; Its purpose is to make full use of the fume afterheat that stove produces, and reduces exhaust gas temperature, saves the energy, although heat exchanger shape in the past and of a great variety, its basic principle all is two kinds of heat transfer process between fluid.Be about to heat exchanger and place in the flue, high-temperature flue gas medium (fluid) is passed to the cryogenic media (air or water) that is given heat in the heat exchanger by heat exchanger with heat, reaches the recovery waste heat resource, the purpose of energy savings.This class device all will have the independent row's (cigarette) of a cover, send (wind, water) system (such as air pump, chimney, blower fan, water pump, pipe network etc.), needs sizable investment, and is to be preceding topic so that heated fluid media (medium) to be arranged.Except giving hot stove self with combustion air or the coal gas, other media of preheating almost are inoperative to the reduction of stove self energy consumption index.Energy-conservation device such as heat exchanger is installed in the flue of stove afterbody in addition, can not produce any good effect for the improvement of the Temperature Distribution in the stove.
The objective of the invention is to seek a kind of novel energy-conserving device, its role is to reduce the furnace gas heat loss, improve the uniformity that temperature field in furnace distributes, strengthen conducting heat and be beneficial to make full use of the heat of stove itself, reduce the fuel consumption of self, this purpose has been satisfied in the invention of netted energy-conservation radiating element.
The structure of netted energy-conservation radiating element and operating position as shown in drawings, flue 1, netted energy-conservation radiating element 2, stove working space 3, burner 4, furnace wall 5 is characterized in that this device is by placing a plurality of individual layer dictyosomes within the stove working space to be formed by stacking.
Because netted energy-conservation radiating element is to be formed by stacking by the heat-resisting dictyosome of several pieces individual layers.Therefore, it have that voidage and specific area are big, gas be easy to by; And radiation ray such as is difficult to see through at characteristics.Be placed on the inside of stove workplace, particularly rear portion, the heat that it can be entrained with gas converts the solid radiant heat effectively to; Even hour at gas flow rate, also has sizable coefficient of heat convection, when high-temperature gas passes through dictyosome, the heat of gas is just passed to mesh element effectively, then, the radiation dictyosome is gone out energy emission with forms of radiation again, this moment is because the bridging effect of dictyosome, the radiant energy of dictyosome rear side is far smaller than the front side, by the anxious brush decline of the gas temperature of dictyosome front side, the entrained heat of gas, major part converts radiant heat to, and dictyosome has certain vapour lock, prevents that hot gas from producing bias current that this will make temperature field in furnace be tending towards homogenising.
As previously mentioned, in order to seek energy-conservation radiating element effect preferably, need the arrangement form between dictyosome material, performance, individual layer dictyosome and mesh size, the number of plies etc. are made one's options, in general: the dictyosome material should have radianting capacity big (blackness is big), anti-oxidant, high temperature resistant, heat shock resistance etc.Wire, refractory fibre rope and the pottery etc. that satisfy above-mentioned requirements all can.Heat exchanging only, the specific area of material is the bigger the better, and promptly twine is thin more good more, but considers that intensity and life-span again should not be too little.During individual layer dictyosome arranged superposed, to guarantee between layer certain distance being arranged, mesh can be straggly mutually, and generally between the 4-10 sheet, more than 10, effect increases dictyosome hardly, and the resistance of gas will increase, and will produce adverse consequences to smoke evacuation system.
Relative heat exchanger in the past, the advantage that the present invention gives prominence to is: equipment is simple, reduced investment, construction easily, can improve stove heating efficiency, improve temperature uniformity, reduce stove tail exhaust gas temperature, energy-saving effect is obvious, also have the stove of preventing tail burn with anger, reduce overflow gas loss, improve effect such as stove tail working condition.
This invention is created and is implemented, and its main structure parameters and effect are as follows:
Material: the 1Cr18Ni9Ti(silk screen); The Fe-Cr-Al(silk screen);
Mesh size: 8 orders
The number of plies: 6 layers
Line footpath: φ 0.55～φ 0.8mm
Shape and size: rectangle 3500 * 500mm
Effect:
1. the dictyosome front and back are the temperature difference: 100-220 ℃;
2. energy-conservation 10-15%;
3. reduce the stove tail and burn with anger, improved working condition.
Claims (4)
1, a kind of industrial furnace is characterized in that with netted energy-conservation radiating element, and it is by placing the folded frame of a plurality of individual layer dictyosomes within the stove working space to form.
2,, it is characterized in that dictyosome is a material with heating resisting metal silk or heat resistance fiber rope, pottery according to the said energy-conservation radiating element of claim 1;
3,, it is characterized in that the dictyosome number is the 4-10 sheet according to the said energy-conservation radiating element of claim 1;
4,, it is characterized in that it is installed in the rear portion of stove working space according to the said energy-conservation radiating element of claim 1.
