Description of drawings
Fig. 1 is the composition frame chart of hydration heat of concrete recycling system among the utility model embodiment;
Wherein, a: concrete; 1: hot conducting system; 2: feed system; 3: discharge system; 4: recovery system; 5: discharging opening; 6: recovery channel.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Figure 1 shows that the composition frame chart of hydration heat of concrete recycling system among the utility model embodiment.As shown in Figure 1, hydration heat of concrete recycling system among the utility model embodiment comprises the hot conducting system 1 that is arranged on concrete a inside, the feed system 2 of heat-conduction medium is provided and collects discharge system 3 through the heat-conduction medium after the interchange of heat for hot conducting system 1, wherein, feed system 2 is communicated with hot conducting system 1, for hot conducting system 1 provides the heat-conduction medium of low temperature, the inner heat of hydration that produces of concrete a is replaced in the heat-conduction medium.Hot conducting system 1 is communicated with discharge system 3, is discharged in the discharge system 3 through the elevated temperature heat transmitting medium after the interchange of heat.
In concrete a coagulation forming process, concrete a is inner to produce a large amount of heats of hydration, and concrete a surface temperature is lower, causes concrete a inside and outside temperature difference to surpass 25 ℃, is easy to generate the crack.The heat-conduction medium of low temperature is provided for the hot conducting system 1 that is arranged on concrete a inside by feed system 2, the inner heat of hydration that produces of concrete a is taken out of by heat-conduction medium through after the interchange of heat, can be according to conditions such as the different-thickness of concrete a, strength grade, environment temperatures, constantly repeat said process, to reduce concrete a to greatest extent, especially the inside and outside temperature difference of the concrete a of large volume avoids concrete a to produce the crack, guarantees workmanship.
Wherein, the heat-conduction medium preferred water, because of its specific heat height, good fluidity make that the efficient of whole interchange of heat is higher, and cost is lower.
For realizing interchange of heat, the hot conducting system 1 in the present embodiment can be made up of the steel pipe (not shown), and the structure of steel pipe can be the clad pipe of straight tube or bend pipe or straight tube and bend pipe.
Because concrete a surface communicates with atmosphere, easily dehydration of surface, make concrete a surface can not get sufficient hydration reaction because of dehydration, therefore need water to come maintenance, guarantee concrete a surface hydration required water, the preferred employing to liquid such as concrete a surface sprinkling irrigation high temperature water carried out maintenance, to reduce concrete a inside and outside temperature difference, reduces the crack.Be the conserve water resource, can carry out the maintenance of concrete a to the elevated temperature heat transmitting medium cycling and reutilization after the interchange of heat in the present embodiment, also taken full advantage of the inner heat of hydration that produces of concrete a, reached the double effects of saving water and energy.Correspondingly, discharge system 3 also comprises the discharging opening 5 that is positioned at concrete a top, for concrete a surface that the elevated temperature heat transmitting medium of discharge system 3 is sprayed.Recovery channel 6 can also be set below concrete a, be used for reclaiming heat-conduction medium, and recovery channel 6 is communicated with a recovery system 4, when the heat-conduction medium temperature reduces, converge heat-conduction medium and collect in the recovery system 4 by recovery channel 6.Wherein, recovery system 4 is communicated with feed system 2, heat-conduction medium in recovery system 4 through precipitation purify satisfy certain specification after (as: when heat-conduction medium is water, need satisfy pH value≤4.5, chloride ion content≤1000mg/L), after namely not destroying concrete a chemical property, offer feed system 2 again and carry out cycling and reutilization, saved great amount of water resources.
As can be seen from the above embodiments, the utility model is by arranging hot conducting system at inside concrete, the low temperature heat-conduction medium that feed system provides carries out interchange of heat with the heat of hydration of inside concrete in hot conducting system, take away heat, reduced the temperature of inside concrete, thereby reduced concrete inside and outside temperature difference, solved because thermal cracking and the shrinkage crack problem that temperature difference produces.And discharge system is set collects through the elevated temperature heat transmitting medium after the interchange of heat, the concrete surface of again the elevated temperature heat transmitting medium being sprayed, carry out concrete maintenance, taken full advantage of the heat of hydration that inside concrete produces, reached the double effects of saving water and energy.After the heat-conduction medium temperature reduces, can be recovered to recovery system and precipitate purification, offer the water inlet system cycling and reutilization again, saved great lot of water resources.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
