The present invention relates to a waste water heat collector for increasing a heat collecting rate by improving a structure of a conventional waste water heat collector, and more specifically, to a waste water heat collector which is capable of conveniently cleaning the upper part of a fresh water inducing pipe, and increasing the collecting rate of waste water heat by smoothly transferring hear between waste water and fresh water by preventing waste water sludge from being deposited and stacked in the upper part of the fresh water inducing pipe in which fresh water flows. According to the waste water heat collector of the present invention, each fresh water inducing pipe of the conventional waste water heat collector is vertically installed in multi steps at an incline in the opposite direction. According to an embodiment of the present invention, the waste water heat collector is capable of easily removing foreign materials in the upper side of the fresh water inducing pipe by spraying high pressure water and air to the upper side of the fresh water inducing pipe since an air supplying pipe and a water supplying pipe for supplying air and water for cleaning are installed to face with each other in a vertical direction in both ends of the outer side of a main body, and an air spraying pipe and a water spraying pipe installed in the lower side of the fresh water inducing pipe inside the main body are connected to the air supplying pipe and the water supplying pipe. According to the present invention, the waste water heat collector has an effect for increasing the heat collecting rate of water water by smoothly transferring heat between waste water and fresh water inside the fresh water inducing pipe by preventing foreign materials contained in waste water from being stacked in the upper side of the fresh water inducing pipe and being changed into sludge in advance by vertically installing the fresh water inducing pipe at an incline in the opposite direction; and increasing the heat collecting rate of waste water by removing foreign materials, such as sludge, etc. stacked in the upper side of the fresh water inducing pipe by spraying high pressure water and air to the upper side of the fresh water inducing pipe by installing the water spraying pipe and the air spraying pipe in the lower side of each fresh water inducing pipe. |
