Technical field
The utility model relates to a kind of fireplace structure.
Background technology
Since our ancestors drilled wood to make fire with the winter protection heating in the cave, fireplace had just occupied critical role in the human residential environment, human several thousand civilization that fireplace can be described as witness.We can imagine that in the winter of cold, the one family is seeing the flare of beating round warm fireplace, and is happy and harmonious.
Yet the middle of last century to last century end, along with the extensive use of coal, natural gas, oil, fireplace fades away as the function of heating, more is to have played a kind of decoration functions, even can be described as a kind of identity status symbol.Tall and big fireplace made of stones has merged consummate sculpture art, and is self-evident, and having this fireplace must have the high chateau that matches with it, and this just can demonstrate owner's power and honorable.
Yet, no matter be the cast iron popular on traditional engraving fireplace made of stones or the nearest American-European market or the modern fireplace of steel plate type, all because design defect has caused many problems, as: dangerous---Mars is emerged easily or CO easily enters indoor (traditional fire), cannot see the flame of beating.In addition, cause because of combustion of wood is insufficient polluting outside the pernicious gas delivery chamber, all have this problem for traditional fire and modern fireplace.In addition, also there is following weakness in traditional fire: 1, overheated or cold excessively.We know, it just can be the most comfortable having only suitable temperature, and no matter tradition still is modern fireplace, and such characteristics are all arranged, timber (or comburant) is when burning, the room can heat up suddenly, has tended to produce overheated temperature since like this, does not only make the people comfortable, and too high temperature also can make indoor air flow change, flow thereby drive dust, cause harm, and the heat that discharges is burnt in the also very fast reduction of room temperature during fire extinguishing irritated patient.2, in order to keep temperature, just have to burn, this in fact combustion has all slatterned more than 50%, has wasted too much comburant always, has also just caused energy waste.
Though today, the efficiency of combustion of heating furnace has reached 90%, the technology that is still the Stone Age that traditional fireplace uses.The efficiency of combustion of fireplace is the highest to be had only about 15%, and, use fireplace also very unhygienic, because updraft and pressure differential, it is discharged hot sucking-off outside the room by chimney within doors.Because in fireplace, fuel combustion is also insufficient, can produce environmental pollution.In fact, some places of the U.S. have forbidden using fireplace in new building.
Summary of the invention
In order to overcome the deficiency that efficiency of combustion is lower, heat utilization efficiency is lower, the feature of environmental protection is relatively poor of existing fireplace, the utility model provides the fuel gas energy-saving environmental protection that a kind of thermal efficiency is higher, heat utilization efficiency is high, environmental-protecting performance is good fireplace.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of fuel gas energy-saving environmental protection fireplace, comprise body of heater, installing with the combustion gas in the described body of heater is the combustion chamber of fuel, form flue gas flow channel between described combustion chamber and the outlet flue, block the accumulation of heat that is provided with porous on the described exhaust gases passes and keep off fiery radiant wall, adopt the catalyzed honeycomb combustion head in the described combustion chamber, scribble the combustion catalyst layer in the honeycomb ceramics of described catalyzed honeycomb combustion head.
Further, described combustion catalyst layer is for containing Pd, Pt, Rh or Au noble metal combustion catalyst, or the perovskite type rare-earth oxide combustion catalyst, or hexa-aluminate series combustion catalyst.
Further again, the surface of described honeycomb combustion head scribbles the far infrared coating.
Further, described body of heater and pyroceram fire door form closed furnace, and described outlet flue is the exhanst gas outlet of described closed furnace, and described outlet flue keeps off bottom between the fiery radiant wall at wall behind the body of heater and accumulation of heat.
Described fireplace also comprises heat exchanger, the gas approach of described heat exchanger is communicated with described outlet flue, the exhanst gas outlet of described heat exchanger is communicated with exhanst gas outlet, and the air intlet of described heat exchanger is communicated with atmosphere, and the air outlet slit of described heat exchanger is communicated with the hot-air inlets of described combustion chamber.
Be provided with the catalytic purification ceramic honey comb in the described exhanst gas outlet, be coated with Pd, Pt, Rh or Au noble metal cleaning catalyst, perovskite type rare-earth oxide cleaning catalyst or mesoporous zeolite molecular sieve type cleaning catalyst in the ceramic honey comb.
Described inboard wall of furnace body is provided with heat-insulation layer.
Technical conceive of the present utility model is: use heat exchanger to reclaim the ember heat, prevent energy loss, the cold air of fuel reaction in heating and the fireplace is used to improve flame temperature and realizes completing combustion.Accumulation of heat shelves fire radiant wall wherein, the preparation of employing exotic material, can stand 1200～1600 ℃ of Fire Radiations and sweep of gases for a long time, the flue gas that fuel combustion produces is through porous regenerator shelves fire radiant wall hole, the heat part that flue gas has is absorbed by porous regenerator shelves fire radiant wall, temperature raise after porous regenerator shelves fire radiant wall was heated, simultaneously heat is passed glass door heating room air by the mode of radiation, improve indoor temperature, porous regenerator shelves fire radiant wall radiant heat can account for 20～40% of gross energy, even higher, is in poised state behind certain hour, absorb flue gas heat on one side, arrive energy emission indoor on one side; Flue gas through porous regenerator shelves fire radiant wall can pass through, and enters heat exchanger, and energy is transferred to combustion air, and flue gas enters outlet flue then, purifies ceramic honey comb purification back through smoke catalytic and discharges, and at this moment temperature is very low.
Improve the heat utilization efficiency of existing fireplace, the cooking stove that a kind of heat-energy losses is little, the thermal efficiency is high, simple in structure is provided.We are from thermodynamic principles: the one, and utilize hot-air combustion-supporting, make full combustion of fuel, make the chemical energy in the fuel more fully be converted into heat energy.The 2nd, strengthen heat insulating effect, make the calorific value of effective utilization bigger, the calorific value of heat radiation is less.The 3rd, make full use of waste heat, reduce smoke discharging residual heat as far as possible.The 4th, introduce accumulation of heat and keep off fiery radiant wall, strengthen infrared radiation heat transfer.
In order to realize environmental protection and reduce the injury of flue gas that we have adopted heterogeneous catalysis, remove the harmful components in the flue gas, realize that fume emission is nuisanceless to human body.
The beneficial effects of the utility model mainly show: the thermal efficiency is higher, heat utilization efficiency is high, environmental-protecting performance is good.
