Abstract
The invention discloses a moist air direct heat exchange technology of a paper-faced plasterboard, and relates to a production technology of a plasterboard production line. In the technology, the high-temperature moist hot air exhausted by a dryer is fed into a special moist air heat exchange device for steam-water heat exchange; the high-temperature water generated after the heat exchange is recycled as the water for the production technology, and the generated air is directly exhausted to the atmosphere; by virtue of a conical spiral spray nozzle and an air evening plate in net-like layout, the moist air heat exchange device can be used for realizing more thorough heat exchange and obvious effect, and utilizes the waste heat of the moist steam to the greatest degree; and moreover, the structure is simple with high efficiency, the heat efficiency of a plasterboard heat supply system is improved, the steam and waste heat resources in the exhaust moist air are reasonably used, the production cost is reduced, and great economic and social benefits are obtained.
Description
Technical field
The present invention relates to the production technology of gypsum board production line, specifically a kind of Thistle board contains humid air direct heat transfer technique.
Background technology
In the Thistle board dry run, for satisfying the requirement of plasterboard drying process, discharge a large amount of water capacities at the hot-air of 130 ℃ of 20-30%, temperature by the drying machine ducting system, contain a large amount of residual heat resources in this air, directly enter atmosphere, caused the waste of heat energy.
Summary of the invention
For solving the technical problem of above-mentioned existence, the invention provides a kind of Thistle board and contain humid air direct heat transfer technique, by simple technology and equipment, the steam in the damp-heat air of realizing discharging in the gypsum board manufacture and the recycling of waste heat.
For achieving the above object, the technical solution used in the present invention is as follows:
Thistle board contains humid air direct heat transfer technique, realize as follows: at first the high temperature damp-heat air that produces in the drying machine is sent into by blower unit and contained the humid air heat-exchanger rig, steam in the high temperature damp-heat air is sprayed cold water and is absorbed, convert high-temperature water to and enter cistern by the gravity outflow, send into workshop through water pump and use as the production technology water, the air after the heat exchange directly enters atmosphere.
The described humid air heat-exchanger rig that contains includes casing, the middle part of described casing is provided with that air inlet, top are provided with the gas outlet, the bottom is provided with outlet pipe, be netted a plurality of cone-type spiral spray nozzles that are provided with on the upper inside wall of casing, be provided with homogenating plate on one section cabinet wall between described air inlet and the described spray nozzle, described outlet pipe is set to S-shaped.
The present invention sends the high temperature damp-heat air of discharging in the drying machine into the special-purpose humid air heat-exchanger rig that contains and carries out steam-water heat exchanging, the high-temperature water that produces after the heat exchange is as the reuse of production technology water, the air that produces directly enters atmosphere, straight mixed spray heat-exchanger rig has designed cone-type spiral shape spray nozzle and the homogenating plate of netted layout, heat exchange is more thorough, effect is remarkable, utilize to greatest extent the airborne steam of hydrofuge and waste heat, efficient simple in structure is high, improved the thermal efficiency of plasterboard heating system, rationally utilize the airborne steam of hydrofuge and residual heat resources, reduced production cost, obtained good economic benefit and social benefit.
