The side wall of each hearth is provided with a pair of air burner and coal gas burner, two air burners, the draught fan and the exhaust fan are connected to the two-position four-way switching valve through air pipelines respectively, the two coal gas burners are communicated with two air outlets of the two-position three-way switching valve respectively, the air inlet of the two-position three-way switching valve is communicated with a coal gas supply device, and an included angle is formed between the gas jetting central lines of the air burner and the coal gas burner in the same hearth. By means of the multi-cavity regenerative heating furnace, air and coal gas are sprayed into the hearths for mixing combustion, the formed smoke flow field and a temperature field can be the best, and quality of billet products is further improved.
Description
Technical field
The utility model belongs to heat treatment technics field, particularly a kind of multi-chamber recuperative heater.
Background technology
Chamber-type heating furnace is used for the heating before metal base or ingot forging and stamping.During heating material, do not move; Not segmentation in stove, require that furnace temperature is even everywhere, for large steel ingot, add the periodic temperature schedule of thermal recovery (being that furnace temperature is divided into warming up period, the period of heating, soaking period etc. by the time), after heating a period of time, need to stop heating to make steel ingot cooling, the heat in this process in furnace chamber can slowly run off, when reheat next time, need to supply with more heat and just can reach the heating effect of expection, energy loss is more, and heat utilization efficiency is lower.Meanwhile, the burner of traditional heating stove is positioned at the top of burner hearth, and heating effect is bad.
Summary of the invention
The purpose of this utility model is for the not high problem of existing heating furnace heat utilization efficiency, and has proposed a kind of alternately heating, and can when cooling, store the multi-chamber recuperative heater of heat.
The purpose of this utility model can realize by following technical proposal: a kind of multi-chamber recuperative heater, it is characterized in that, it comprises two burner hearths, two-position four-way transfer valve, two-position three-way switching valve, air inlet fan and exhaust blower, the sidewall of each burner hearth is equipped with a pair of air burner and coal gas burner, two air burners and air inlet fan and exhaust blower are all connected on two-position four-way transfer valve by air duct, described air inlet fan and exhaust blower all can selectively be communicated with two air burners, two coal gas burners are communicated with respectively on two gas outlets of two-position three-way switching valve, the air inlet of two-position three-way switching valve is communicated with gas supply device, the gas jet center line of the air burner in same burner hearth and coal gas burner forms angle.
Described angle is 25-35 °.
Between described air burner and two-position four-way transfer valve, be communicated with regenerator, in regenerator, be provided with heat storage.
Described heat storage is honeycomb ceramic heat accumulator.
Compared with prior art, the air of this multi-chamber recuperative heater and coal gas are blown into by different pipelines respectively, and there is incident angle, make air and coal gas spray into the formed flue gas flow field of mixed combustion and temperature field in burner hearth and can reach best, at utmost guaranteed the uniformity in the temperature field of steel billet, make the CO imperfect combustion phenomenon in burner hearth reduce to minimum, further improved steel billet product quality.In addition, two groups of burner hearth alternately operatings, wherein one group while stopping heating, by exhaust blower, the heat in this burner hearth is taken away and stored, while by the time again blowing heating, then the heat of originally storage to be sent back in burner hearth, thermal losses is less, and heat utilization efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of this multi-chamber recuperative heater;
In figure, 1, burner hearth; 2, air burner; 3, coal gas burner; 4, exhaust blower; 5, two-position four-way transfer valve; 6, air duct; 7, air inlet fan; 8, two-position three-way switching valve; 9, regenerator; 91, heat storage; 10, steel billet.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, this multi-chamber recuperative heater has two burner hearths 1, the sidewall of each burner hearth 1 is equipped with a pair of air burner 2 and coal gas burner 3, two air burners 2 and air inlet fan 7 and exhaust blower 4 are all connected on two-position four-way transfer valve 5 by air duct 6, described air inlet fan 7 and exhaust blower 4 all can selectively be communicated with two air burners 2, two coal gas burners 3 are communicated with respectively on two gas outlets of two-position three-way switching valve 8, the air inlet of two-position three-way switching valve 8 is communicated with gas supply device, air burner 2 in same burner hearth 1 and the gas jet center line of coal gas burner 3 form angle, angle is 25-35 °.Between air burner 2 and two-position four-way transfer valve 5, be communicated with regenerator 9, be provided with heat storage 91 in regenerator 9, described heat storage 91 is honeycomb ceramic heat accumulator 91.
Operating room, gas supply device passes through a two-position three-way switching valve 8 burner hearth 1 supply coal gas wherein, two-position four-way transfer valve 5 switches to corresponding station, the air burner 2 that air inlet fan 7 is corresponding with this burner hearth 1 is communicated with, air sprays into burner hearth 1 after air duct 6 and regenerator 9, coordinate burning with coal gas, to steel billet 10 heating, steel billet 10 is heated to assigned temperature; Next, switch two-position three-way switching valve 8 and two-position four-way transfer valve 5, stop this burner hearth 1 supply coal gas and air, then to another burner hearth 1 supply coal gas and air, now, exhaust blower 4 is communicated with the air burner 2 of burner hearth 1 formerly, and the flue gas in this burner hearth 1 is extracted out, during flue gas process regenerator 9, heat is absorbed by heat storage 91.While again switching two-position three-way switching valve 8 and two-position four-way transfer valve 5, when air inlet fan 7 is blown into air, again the heat in heat storage 91 is blown back to burner hearth 1, improve the efficiency of heating surface, recycled heat simultaneously.When one of them burner hearth 1 stops heating, then another burner hearth 1 is bled, principle is identical, and two burner hearths 1 replace heating operation.
