All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The core of the utility model is to provide a heat preservation device for sewage treatment, which has good heat preservation effect on sewage. The utility model also provides a sewage treatment device comprising the heat preservation device for sewage treatment, which is beneficial to ensuring that sewage has proper temperature.
Fig. 1 is a schematic structural diagram of a heat preservation apparatus for sewage treatment according to an embodiment of the present invention. In fig. 1, the direction of the arrow indicates the circulation direction of the cooling water.
The utility model provides a heat preservation device for sewage treatment, which comprises a sewage tank 1 and an insulation box 2, wherein the sewage tank 1 is used for containing sewage, the sewage tank 1 is a heat-conducting sewage tank, the sewage tank 1 is arranged inside the insulation box 2, and water and heat storage balls 3 are arranged between the sewage tank 1 and the insulation box 2 so as to adjust the temperature of the sewage in the sewage tank 1 by utilizing the heat absorption or heat release of the heat storage balls 3 during phase change.
The heat storage balls 3 serve as a phase change heat storage material that stores or releases energy by utilizing a physical phenomenon in which a large amount of latent heat of phase change is absorbed or released in a phase change process (conversion between a solid state and a liquid state) of a substance. The water between the sewage tank 1 and the heat preservation tank 2 is used as a conductive medium of the heat storage ball 3.
In the concrete working process, when the temperature of the sewage entering the sewage tank 1 is higher than the set temperature value, the sewage tank 1 is a heat conducting sewage tank, so that the heat storage balls 3 can be excited, the phase change reaction of the heat storage balls 3 starts, the heat storage balls 3 absorb heat and are changed into liquid from solid state, the waste heat in the sewage can be stored, and the temperature of the sewage is reduced to the set temperature value. When the temperature of the sewage in the sewage tank 1 is lower than the set temperature value, the heat storage balls 3 are excited to release heat, so that the temperature of the water between the sewage tank 1 and the heat preservation tank 2 is increased, and the heat released by the heat storage balls 3 is conducted into the sewage by utilizing the heat conductivity of the heat conducting sewage tank, so that the aim of increasing the temperature of the sewage is fulfilled.
Therefore, the heat storage ball 3 is placed in the water between the sewage tank 1 and the heat insulation tank 2, so that the heat insulation tank 2 can form an effect similar to a heat storage water tank for supplying heat, an efficient heat storage and insulation system is formed, the constant temperature of sewage can be kept, and the heat insulation effect is good.
Because the energy that the phase change heat storage material of unit volume can store is far greater than the scope that sensible heat energy storage material of unit volume can bear, consequently rely on 3 phase transition in-process of heat storage ball to shift a large amount of latent heats, can promote heat preservation efficiency, and then furthest promotes sewage treatment efficiency. The practical application shows that: the heat storage capacity of the heat storage ball 3 can reach over five times of the same volume of normal pressure water.
It should be noted that, the specific phase transition temperature of the heat storage balls 3 and the amount of heat absorbed and released during the phase transition process are not specifically limited in the present invention, as long as the amount of heat absorbed and released by the heat storage balls 3 can satisfy the sewage temperature adjustment range.
Further, in order to avoid the phenomenon that the temperature of the sewage in the sewage tank 1 is too high and the temperature of the sewage cannot be reduced to a reasonable range by the heat absorption of the heat storage balls 3, the water between the sewage tank 1 and the heat insulation tank 2 is cooling water based on the above embodiment. That is, the present embodiment utilizes the combined action of the heat storage balls 3 and the cooling water to reduce the temperature of the sewage, so that the temperature of the sewage meets the requirement, and the temperature of the sewage is prevented from being too high.

In order to realize the automatic control of the circulating pump 4, on the basis of the above embodiment, a water temperature detector is arranged in the sewage tank 1, the water temperature detector is connected with a controller, and the controller is connected with the circulating pump 4, so that the controller controls the starting and stopping of the circulating pump 4 according to the detection result of the water temperature detector. That is to say, when the temperature of the sewage in the sewage tank 1 exceeds the first set value, the controller controls the circulating pump 4 to start, so as to realize the circulation of the cooling water and improve the cooling effect. When the temperature of the sewage in the sewage tank 1 reaches a second set value (required temperature), the controller controls the circulating pump 4 to stop working.
Therefore, the automatic control of the circulating pump 4 can be realized, the automation degree of the device is improved, unattended operation can be realized, and the operation cost is reduced.
