Abstract

The invention discloses a heat recovery system of a gypsum board drying exhaust steam filling tower. The heat recovery system comprises a dryer (1), a hot blast stove (2) and a filling tower (3), the dryer (1) is connected with a heat exchanger a (21) through one branch of a circulating fan (4), the other branch of the circulating fan (4) is connected with a heat exchanger b (11) of the dryer (1), and the heat exchanger b (11) is connected with the filling tower (3) through a moisture removing fan (5). Recycling of moisture-removing steam generated by a gypsum board dryer is realized through a simple structure, one branch is used for a dryer hot blast stove heat exchanger to avoid heat energy loss caused by cold air heat exchange, the other branch recycles heat to the dryer through a dryer heat exchanger, and moisture-removing air after heat exchanging reenters the filling tower for condensing to enter a hot water tower to be used for living auxiliary water, so that the moisture-removing air generated by the dryer is enabled to be fully recycled, waste of heat energy is reduced, and production cost is lowered.

Description

The dry steam discharge packed tower heat recovery system of a kind of plasterboard
Technical field
The present invention relates to gypsum board production line waste heat recovery apparatus, specifically a kind of plasterboard dry exhaust packed tower heat recovery system.
Background technology
In plasterboard dry run, production line discharges a large amount of steam, is directly discharged into atmosphere and forms a large amount of thermal waste.The a large amount of steam waste heat resource of discharge after gypsum board manufacture is dry, 150 ℃ of left and right of temperature, drying machine discharge capacity per hour is that evaporated water is 2.3-2.7kg/m 2, produce the plaster tablet drying machine of 3,000 ten thousand squares per year, waste vapour per hour is arranged the steam 10-12 ton of normal pressure 90-150 ℃ outward, and waste heat discharge capacity is very large.
Summary of the invention
For solving the technical problem of above-mentioned existence, the invention provides a kind of plasterboard dry exhaust packed tower heat recovery system, the hydrofuge air Fen Ji road of drying machine is back to and is produced and domestic water, obviously reduce the waste of heat energy.
For achieving the above object, the technical solution adopted in the present invention is:
The dry steam discharge packed tower heat recovery system of a kind of plasterboard, comprise drying machine, hot-blast stove and packed tower, described drying machine is connected with the heat exchanger a of hot-blast stove by circulating fan one tunnel, and another road is connected with the heat exchanger b of drying machine 1, and described heat exchanger b is connected with packed tower by wet-emitting blower.
The exhausted steam that the present invention produces plaster tablet drying machine by simple structure carries out reuse, one tunnel is for drying machine heat exchanger for hot-blast stove, reduce the heat-energy losses that cold wind heat exchange causes, heat is back to drying machine by the drying machine heat exchanger of separately leading up to, hydrofuge air after heat exchange enters packed tower condensation again and enters hot-water tower, and for the auxiliary water of living, the hydrofuge air that drying machine is produced has obtained sufficient reuse, reduce the waste of heat energy, reduced production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Describe the present invention below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, this plasterboard is dried steam discharge packed tower heat recovery system, comprise drying machine 1, hot-blast stove 2 and packed tower 3, described drying machine 1 is connected with the heat exchanger a21 of hot-blast stove 2 by circulating fan 4 one tunnels, another road is connected with the heat exchanger b11 of drying machine 1, and described heat exchanger b11 is connected with packed tower 3 by wet-emitting blower 5.
The exhausted steam that plaster tablet drying machine produces is realized and is divided into two-way under circulating fan 4 effects, and a road enters the heat exchanger a21 of hot-blast stove 2, as heat exchanger a21 heating air heat source; Another road enters the heat exchanger b11 of drying machine 1, and as heat exchanger, b11 adds heated air source, realizes hot-air after heat exchange as the pre-hot blast of plaster tablet drying machine 1.
Hydrofuge air after heat exchanger b11 in addition, contains large quantity of moisture and enters steam discharge packed tower 3 and carry out condensation recovery, realizes steam is converted to hot water reclaims, and the hot water after recovery is produced auxiliary water.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present invention, also should belong to protection scope of the present invention.
