Abstract
The invention discloses a regenerative inclined-bottom heating furnace which is mainly composed of an inclined-bottom heating furnace, a left regenerative chamber, a right regenerative chamber, a heataccumulator-ceramic ball, a change valve, a gas inlet pipe and a gas exhaust pipe. The furnace is characterized in that an efficient regenerative conversion device is combined with the traditional inclined-bottom heating furnace so that heat of high-temperature smoke generated by the traditional inclined-bottom heating furnace is exchanged with that of from one or a plurality of or dozens of theregenerative chambers, so the heat is mostly reused, thus improving thermal efficiency and saving energy.
Description
Affiliated technical field
The invention belongs to a kind of regenerative inclined-bottom heating furnace in the machine industry.
Background technology
Traditional inclined-bottom heating furnace is not provided with the accumulation of heat conversion equipment that reclaims fume afterheat mostly, so this traditional inclined-bottom heating furnace high-temperature flue gas waste heat can not be recycled, wastes energy.
Summary of the invention
The objective of the invention is to design a kind of on inclined-bottom heating furnace design and installation one cover reclaim the accumulation of heat conversion equipment of high-temperature flue gas waste heat.The accumulation of heat conversion equipment mainly is made up of regenerator, heat storage-Ceramic Balls or ceramic honeycomb body, reversal valve, air feed and smoke evacuation system.In the both sides of inclined-bottom heating furnace respectively design and installation a pair of, several to or tens pairs of regenerator, be full of Ceramic Balls or ceramic honeycomb body in the regenerator.Operation principle is: at first, normal temperature air enters the left side regenerator from admission line by reversal valve, the heat storage (as Ceramic Balls) of in the regenerator of left side, flowing through from bottom to top, normal temperature air enters burner hearth after being heated to higher temperature (reaching as high as 800-1100 ℃) by heat storage, with coal gas mixed combustion.Combustion product-high-temperature flue gas is discharged after by right side regenerator accumulation of heat, the high-temperature flue gas heat storage of in the regenerator of right side, flowing through from top to bottom, heat is passed to Ceramic Balls and heat is accumulated in the Ceramic Balls, high-temperature flue gas itself is cooled to below 150 ℃ simultaneously, is discharged into the air from discharge duct behind reversal valve.Through after a few minutes, right side accumulation of heat intimate heat accumulate saturated after, control system is handled the reversal valve action, makes normal temperature air flow to the right side regenerator behind reversal valve, enters burner hearth after being heated in the regenerator of right side.Meanwhile, the heat storage in the regenerator of right side is cooled, and has obtained heat storage capacity again.Enter in the burner hearth and coal gas mixed combustion by the hot-air after the right side regenerator heating, the high-temperature flue gas of generation is discharged after by left side regenerator accumulation of heat, and the high-temperature flue gas that is cooled is discharged into the air from discharge duct behind reversal valve.Coal Jie effect of temporarily accumulating heat has been played in two regenerator alternations again and again like this, heat storage in this process, the said structure design has realized purpose of the present invention.
Advantage of the present invention is that the high-efficiency thermal storage conversion equipment is combined with traditional inclined-bottom heating furnace, the heat that makes the high-temperature flue gas that the burning of traditional inclined-bottom heating furnace produces by a pair of, several to or the exchange heat major part of tens pairs of regenerator be reused, improve the thermal efficiency, saved the energy.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, inclined-bottom heating furnace (6) is oval domes, a pair of left side regenerator (7) and right side regenerator (5) are set in the both sides of inclined-bottom heating furnace (6), be full of heat storage-Ceramic Balls (8) in left side regenerator (7) and the right side regenerator (5), between left side regenerator (7) and the right side regenerator (5) reversal valve (2) is set, be connected by two connecting pipes (4) between reversal valve (2) and left side regenerator (7) and the right side regenerator (5), admission line (1) is connected with reversal valve (2) respectively with discharge duct (3).The course of work is: at first, normal temperature air enters left side regenerator (7) from admission line (1) by reversal valve (2), heat storage-the Ceramic Balls of in left side regenerator (7), flowing through from bottom to top (8), normal temperature air enters burner hearth after being heated to higher temperature (reaching as high as 800-1100 ℃) by heat storage-Ceramic Balls (8), with coal gas mixed combustion.Combustion product-high-temperature flue gas is discharged after by right side regenerator (5) accumulation of heat, high-temperature flue gas heat storage-the Ceramic Balls (8) of in right side regenerator (5), flowing through from top to bottom, heat is passed to heat storage-Ceramic Balls (8) and heat is accumulated in heat storage-Ceramic Balls (8), high-temperature flue gas itself is cooled to below 150 ℃ simultaneously, is discharged in the air by discharge duct (3) through reversal valve (2).Through after a few minutes, interior the heat of right side regenerator (5) accumulate saturated after, control system is handled reversal valve (2) and is moved, and makes normal temperature air flow to right side regenerator (5) behind reversal valve (2), enters burner hearth after being heated in right side regenerator (5).Meanwhile, the normal temperature air cooling that the heat storage-Ceramic Balls (8) in the right side regenerator (5) is passed through has obtained heat storage capacity again.Enter in the burner hearth and coal gas mixed combustion by the normal temperature air after right side regenerator (5) heating, the high-temperature flue gas of generation is by discharging from discharge duct (3) by reversal valve (2) after left side regenerator (7) accumulation of heat.About two regenerator alternations again and again like this, Ceramic Balls has played coal Jie effect of temporarily accumulating heat in this process.
