Description
Technical field
The utility model relates to the water of condensation recovery technology, relate in particular to a kind of can reclaim fast iron and steel make in the device of water of condensation heat-exchange system water of condensation in the alkali cleaning section steam heating system.
Background technology
Cold rolled strip will be removed the residual grease in rolling rear surface, iron powder, the ash dirt that grades through cleaning unit usually, clean unit operated by rotary motion multilevel cleaning device, comprise that alkali spray tank, alkali scrubs groove, electrolytic cleaning tank, water and scrub groove, water spray tank etc., and the scavenging solution circulation tank is set respectively realizes continuous wash with steel.Because cleaning performance is better under the band steel certain temperature, in order to guarantee good clean effect, in circulation tank, adopt heated wash alkali lye and rinse water, keep rinse liquid temperature within the specific limits.Because steam heating is effective, cost is low, cleans unit and generally adopts steam to come heated wash liquid to make it keep certain temperature as heating medium by coil heat exchanger and scavenging solution heat exchange.Steam becomes water of condensation after heat exchange, if directly enter in the lye vat, can reduce on the one hand the concentration of scavenging solution, is unfavorable for cleaning; On the other hand, because the water quality of water of condensation approaches or reached the water quality of pure water substantially, can be used as the make up water of other waters of unit and recycle, directly discharge the theory that does not meet the modern industry energy-saving and emission-reduction.
At present, the Iron and Steel Production field generally is water of condensation to be sent in the water cycle tank of last step water spray tank reclaim to the recovery of water of condensation.In the unit of actual motion, generally be that the exit end at interchanger arranges drain valve, discharge condensation water to the meeting of water cycle tank.Unobstructed for draining, the drain valve operated by rotary motion is in lower position, and water cycle tank water level is high, water return outlet is generally in higher position, cause the drain valve backwater not smooth, appear in the continuous operational process water of condensation and near the interchanger water pipe, accumulate, cause the viscous flow phenomenon.Viscous flow will cause occurring in the interchanger phenomenons such as water hammer, temperature be unstable, shorten the interchanger life-span, affect heat transfer effect.In addition; after unit is shut down in debug phase or production process; owing to generally the heat exchanger entrance steam valve will be closed; the part vapor condensation of remnants in the interchanger; and drain valve causes its draining to stop because the inlet/outlet pressure difference disappears, and this will cause can't draining, and heat exchanger tube is residual the water of condensation that does not drain; so that again during operating unit, be difficult to drain as early as possible this part remaining water of condensation.Therefore, it is necessary to improve the recovery system of coil heat exchanger steam condensate.
Summary of the invention

For solving the problems of the technologies described above, the utility model provides the retrieving arrangement of water of condensation in a kind of steam heating system, comprise heat exchanger tube and water circulation tank, also comprise an airtight accommodating cavity, described accommodating cavity one end is communicated with heat exchanger tube by transfer lime, and the other end is communicated with water circulation tank by recovery tube; Described accommodating cavity also is communicated with the steam line of heat exchanger tube by pneumatic tube, and described pneumatic tube is provided with valve.Airtight accommodating cavity temporarily stores the water of condensation that heat exchanger tube flows out as a small-sized pond for recovering by transfer lime, has guaranteed the timely discharging of water of condensation in the heat exchanger tube in the water of condensation removal process.When water of condensation reached a certain amount of in accommodating cavity, with existing steam input accommodating cavity in the interchanger steam line, the air pressure by its generation imported water circulation tank with water of condensation by recovery tube, finishes once and reclaims by pneumatic tube.The utility model retrieving arrangement need not set up heating or the pressure exerting device of high energy consumption, utilized cleverly the existing steam in the interchanger steam line that air pressure is provided, water of condensation is pressed into water circulation tank, pipeline in the whole recovery system can keep the unobstructed of higher degree, and recovery speed is fast, efficient energy-saving.
As preferably, be provided with water level sensor in the described accommodating cavity, described valve is the automatic electromagnetic valve that is subjected to described water level sensor control.Water level in the water level sensor monitoring accommodating cavity is set, and with the automatic electromagnetic valve on the Data Control gas pipe line that monitors, has realized the automatization of recovery system, do not need personnel on duty, simple and practical.
As preferably, described transfer lime is provided with the first vacuum breaker.This vacuum breaker is used for preventing water of condensation from the transport pipe internal reflux to heat exchanger tube, guarantees that transport pipe is unobstructed.
As preferably, be provided with the second vacuum breaker on the described recovery tube.This vacuum breaker is used for preventing that water of condensation is back to accommodating cavity from recovery channel, guarantees the unobstructed of recovery channel.
As preferably, be provided with vapor pipe on the described accommodating cavity, be provided with vent valve on the affiliated vapor pipe.The vapor pipe that is provided with vent valve on the accommodating cavity plays the optionally effect of discharged steam, guarantees the unobstructed of recovery system.
The utlity model has simple in structure, reclaim fireballing characteristics, and cost is low, capacity usage ratio is high, meets the theory of modern industry energy-saving and emission-reduction.
