Description
Technical Field
The utility model relates to a heating technical field especially relates to an utilize system of heat air exhaust and supplementary heat supply of phase change heat storage material.
Background
Currently, in the field of industrial projects, due to the special requirements of process equipment, there are many situations in which it is necessary to discharge a large amount of waste heat generated by the process equipment in order to ensure the normal operation of the process equipment. In a general treatment mode, hot exhaust air generated by process equipment is uniformly exhausted to the outside through a hot exhaust fan, and although the use requirement of the process equipment is met, the method affects the microenvironment near an industrial factory building. In winter, a large amount of waste heat is discharged to the outside, which is a waste of resources.
In recent years, more and more industrial design projects have begun to pay attention to the recovery of hot exhaust air, but there are many problems. Firstly, the recovery of hot exhaust air is usually only stopped at the concept stage, and no good implementation mode exists; secondly, most of the existing heat exhaust recovery modes are directly sent back to the indoor, the effect of auxiliary heat supply is difficult to guarantee, and the heat exhaust is still directly exhausted to the outdoor in summer, or the waste heat energy cannot be effectively recovered.
The phase change heat storage material is a novel chemical material capable of storing heat energy. It undergoes biological change at a specific phase transition temperature, and with the absorption or release of heat, can be used to control the temperature of the surrounding environment, or to store thermal energy. It stores heat or cold and releases it when necessary, thus improving the utilization rate of energy. The phase-change heat storage material is used for storing the heat of hot exhaust air and releasing the heat at a certain phase-change temperature so as to achieve the purpose of auxiliary heat supply.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide an utilize heat to air exhaust and the supplementary heat supply's of phase change heat storage material system, can realize when the phase change temperature of process equipment exhaust hot-blast arrival phase change heat storage material, phase change material absorbs the temperature that heat was aired exhaust, get up this part heat storage, treat the ambient temperature decline back, thereby phase change heat storage material takes place the phase transition because the change of temperature, the heat that will store releases, reach the purpose of supplementary heat supply.
The utility model discloses a realize through following technical scheme: the utility model provides an utilize system of heat air exhaust and supplementary heat supply of phase change heat storage material, includes phase change heat storage material device, phase change heat storage material device has the heat exchanger through first heat supply pipe connection, the heat exchanger has fan coil through second heat supply pipe connection, be provided with the special pump of phase change heat storage material on the first heat supply pipe, be equipped with water pump and valve on the second heat supply pipe, water pump and valve pass through second heat supply pipe intercommunication.
Furthermore, the water pump and the valve are connected with a temperature controller through a third heating pipeline.
Furthermore, a water replenishing device is connected to the second heating pipeline.
The utility model has the advantages that: compared with the prior art, the hot exhaust air is not directly sent to indoor heating, so that the condition that the hot exhaust air of some processes contains substances harmful to human bodies and the heat source of the hot exhaust air cannot be utilized is avoided; the hot exhaust does not directly heat the water in the fan coil, but adopts a mode of heat exchange between the phase change heat storage material and the water, so that the stability of a heat source is ensured, and the heat supply effect is obviously improved; the hot exhaust air can be utilized in winter, and the phase change heat storage material can also store heat in summer, so that a more objective auxiliary heat source is provided in winter.

Fig. 1 is a schematic front view of the present invention;
in the figure: 1. a phase change thermal storage device; 2. a heat exchanger; 3. a fan coil; 4. a temperature controller; 5. a water pump; 6. a valve; 7. a pump dedicated for phase change heat storage materials; 8. a water replenishing device; 9. a first heating line; 10. a second heating line; 11. a third heating line.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model discloses a phase change heat storage material device, phase change heat storage material device has heat exchanger 2 through first heat supply pipeline connection, heat exchanger 2 is connected with fan coil 3 through second heating pipeline 10, be provided with phase change heat storage material special pump 7 on the first heat supply pipeline, be equipped with water pump 5 and valve 6 on the second heating pipeline 10, water pump 5 and valve 6 communicate through second heating pipeline 10.
Further, the water pump 5 and the valve 6 are connected to a temperature controller 4 through a third heating line 11.
Further, a water replenishing device 8 is connected to the second heating pipeline 10.
When heat is needed to be supplied in winter, the special pump 7 for the phase-change heat storage material, the water pump 5 and the valve 6 are opened, hot exhaust air generated by process equipment passes through the phase-change heat storage device 1, the phase-change heat storage material absorbs heat of the hot exhaust air and reaches phase-change temperature, then the heat is changed from solid state to liquid state, the liquid phase-change heat storage material passes through the heat exchanger 2 through the special pump and exchanges heat with cold water in the heat exchanger 2, the phase-change heat storage material releases heat after meeting the cold water to enable the temperature of the water to rise, after the hot water passes through the fan coil 3, the fan coil 3 enables the air to exchange heat with the hot water to. Wherein the water replenishing device 8 can add water to the second heating line 10 to prevent the shortage of the heating load.
When heat supply is not needed in summer, the special pump 7 for the phase-change heat storage material, the water pump 5 and the valve 6 are closed, hot exhaust air generated by the process equipment passes through the phase-change heat storage device 1, the phase-change heat storage material absorbs heat of the hot exhaust air and changes from a solid state to a liquid state after reaching a phase-change temperature, at the moment, the special pump 7 for the phase-change heat storage material stops working, and the phase-change heat storage material only stores the heat and does not exchange heat. And when the ambient temperature is lower than a set value, the special pump 7 for the phase change heat storage material, the valve 6 and the water pump 5 are started through the temperature controller 4 to exchange heat.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
