Abstract
The invention relates to a heat accumulating type combustion device for a heat accumulating ball on-line changing. Based on an ordinary heat accumulating type combustion device, the original structure form is changed, and a charging and discharging device of a heat accumulator with an inclination angle movable opening is designed. Once the condition that the heat accumulating type accumulator is blocked by dust and the normal operation is influenced happens, a discharging opening can be opened to discharge the heat accumulating ball, simultaneously the charging opening can be opened to charge a new heat accumulating ball, and thereby the heat accumulating type combustion device can ensure that when the heat accumulating ball is changed, the furnace can not be shut down.
Description
Technical field
The present invention relates to a kind of heat accumulating burner capable, particularly a kind of heat accumulating burner capable of online replacing heat-storing sphere.
Background technology
The greatest problem that runs in the existing heat-storage type burner use is: after using the regular period, heat storage is easy to be stopped up by the dust in the flue gas, thereby influenced the circulation of flue gas and combustion air, caused waste heat not utilize to greatest extent, if can not dredge timely and effectively, will influence the operate as normal of burner, and worsen the thermal technology state of stove, therefore also just can not embody the own characteristic of heat-storage type burner fully.
The means that address this problem at present just need blowing out to change heat storage normally after heat-storage type burner uses a period of time, and this will more or less have influence on the operate as normal of stove.
Summary of the invention
The present invention be directed to existing heat-storage type burner heat storage is easy to be stopped up by the dust in the flue gas, influenced the problem of the circulation of flue gas and combustion air, a kind of heat accumulating burner capable of online replacing heat-storing sphere has been proposed, on the basis of common heat-storage type burner, change original version, be designed to have the adding and the tapping equipment of the heat storage of active open.Like this, when influencing its operate as normal in case the situation of being stopped up by dust appears in heat-storage type burner, just can be when opening floss hole and emitting dirty heat-storing sphere, also open and adding inlet and put into new heat-storing sphere, be unlikely to blowing out when so just can guarantee to change heat-storing sphere.
Technical scheme of the present invention is: a kind of heat accumulating burner capable of online replacing heat-storing sphere, comprise burner, heat storage and fume extractor, and combine closely, gas is in the burner hearth combustion space, heat storage, fume extractor, circulation hockets repeatedly in the heat storage, described heat storage comprises screen, heat-storing sphere, floss hole, add inlet, mouth is threaded, seal cover, heat-storing sphere is equipped with in heat storage inside, screen is arranged at the bottom, the floss hole of heat-storing sphere is set along the screen bottom, the inlet that adds of heat-storing sphere is set on heat storage top, floss hole is respectively arranged with seal cover with adding to enter the mouth, be used for sealing, floss hole is downwards with level respectively with the angle of inclination that adds inlet and the angle of cut that makes progress is 15 °～20 °.
Described floss hole and the diameter that adds inlet are 4～6 times of heat-storing sphere diameter.Described floss hole and add inlet and be provided with the mouth that is threaded respectively, seal cover respectively and mouthful coupling that is threaded are convenient to dismounting.
Beneficial effect of the present invention is: the heat accumulating burner capable of the online replacing heat-storing sphere of the present invention, can make High-temp. kiln under the situation of not blowing out, carry out online replacing heat-storing sphere, thereby guarantee the normal operation production of stove, improved production capacity, avoid blowing out, the reduction that brings unnecessary energy loss and production capacity owing to the obstruction of heat-storage type burner.
Description of drawings
Fig. 1 is the heat accumulating burner capable operation principle schematic diagram of the online replacing heat-storing sphere of the present invention;
Fig. 2 is a heat storage body structure schematic diagram in the heat accumulating burner capable of the online replacing heat-storing sphere of the present invention.
The specific embodiment
The heat accumulating burner capable operation principle schematic diagram of online as shown in Figure 1 replacing heat-storing sphere, heat accumulating burner capable is that burner hearth combustion space 1, heat storage 2 (heat-exchange device), fume extractor 3 are closely combined, constitute a compact conformation, the heating plant that has preeminent performance.Utilize air-introduced machine, pass through burner channel, draw the furnace high-temperature flue gas in the burner hearth combustion space 1, through heat storage 2 fume afterheat is passed to heat storage 2 to high temperature, feed combustion air (coal gas) through commutation back in the fume extractor 3, the heat of heat storage 2 savings is passed to air (coal gas), it is preheated to high temperature, enter combustion-supporting in the burner hearth combustion space 1 (burning) through burner channel.Heat accumulating burner capable needs timing reversing, and when one of them added hot-air (coal gas) burning, another then by flue gas heating heat storage, hocketed repeatedly.
The characteristics of high-efficiency heat-accumulating burner are high efficiente callback waste heats at high temperature, and exhaust gas temperature is less than 150 ℃; Can obtain waste heat recovery efficient greater than 80%; Fuel consumption is low, and energy-saving effect is remarkable, than existing common burner energy-conservation 30%～50%; The fire box temperature good uniformity utilizes the high-temp combustion technology, and the alternate combustion mode changes Temperature Distribution in the stove, can obtain the fire box temperature of homogeneous, and the temperature difference is less than 5 ℃; The residual neat recovering system compact conformation has been realized the small and exquisite integrated of heat storage and burner; Environment protecting is obvious.Owing to can realize high-temperature and low-oxygen combustion, nitrous oxides concentration greatly reduces in the flue gas.
Adopt the mode of alternate combustion (heat exchange) to move, when (or one group) preheated air heat supply burning, another (or one group) is got rid of flue gas and is heated heat storage, and timing reversing hockets repeatedly.
Heat storage body structure schematic diagram in the heat accumulating burner capable of online as shown in Figure 2 replacing heat-storing sphere, making original heat storage 2 lower horizontal screens into angle of inclination is 15 °～20 ° screen 13, so that in time the emitting fast of dirty heat-storing sphere 17.
Change the mode of original blowing out integral replacing heat-storing sphere, the floss hole 16 of dirty heat-storing sphere is set along screen 13 bottoms, be provided with on heat storage 2 tops new heat-storing sphere add the inlet 12, floss hole 16 and add inlet 12 and be provided be threaded mouthful (15,11) respectively, seal cover (14,10) mates be threaded mouthful (15,11) respectively, is used for sealing, is convenient to dismounting, can change the dirty heat-storing sphere 17 that stops up regenerator so at any time, and heat is not lost.Floss hole 16 is downwards with level respectively with the angle of inclination that adds inlet 12 and the angle of cut that makes progress is 15 °～20 °, and its diameter d is 4～6 times of heat-storing sphere 17 diameters.
