Device for recycling heat energy of shower waste water

Abstract

The invention discloses a technical device which is reliable in operation and is suitable for recycling the heat energy of the shower waste water of all bath centers. The device comprises a hot water tank, a warm water tank, a water-containing tray heat exchanger and a warm water and tap water synchronous and equivalent drain/inlet valve. The technical device can be realized through the measures as follows: when taking a shower, a human body stands on a partition plate, the waste hot water of the shower leaks from the partition plate to the water-containing tray heat exchanger, and the upper surface of a water-containing tray is provided with a heat exchange plate (a stainless steel plate or an aluminum plate), and the lower surface of the water-containing tray is provided with a heat exchange pipe. Tap water flows to the warm water tank in the reverse direction together with the shower waste water through the heat exchange pipe of the heat exchanger. When the shower is carried out, a warm water valve is opened firstly, and then, a hot water valve is opened when the water temperature of the shower cannot meet the requirement, so that the water temperature is increased to the temperature required by the shower. The warm water valve and a tap water inlet valve of the shower are synchronously and equivalently controlled, thus, the tap water inlet valve automatically opens when the warm water valve is opened, and warm water discharged from the warm water tank enters the warm water tank after heat exchange is carried out on the warm water by equivalent tap water. When a shower room is cleaned every day, the partition plate can be opened to clean the heat exchange plate of the water-containing tray heat exchanger, thereby, filth blockage is avoided, and the heat exchange efficiency of the heat exchanger is improved.

Description

technical field [0001] The invention relates to a device for extracting and recycling heat energy of shower waste hot water in a bathing center, and belongs to a heat energy recovery and recycling technology device that utilizes a heat exchanger to replace and extract heat energy in shower waste water and heat new water. Background technique [0002] Because the shower waste hot water in the bathing center contains a lot of unclean substances, and the unstable flow and water temperature have brought many technical obstacles to the recovery of heat energy, people have to completely discharge the waste hot water after showering. Because the human body does not absorb much heat energy during the shower process, the temperature of the discharged water is still above 36°C, and the hot water above 36°C is discharged in vain, resulting in a large amount of waste of heat energy. [0003] In this regard, some technical schemes try to build a waste water pond, store the waste water, a...

Problems solved by technology

However, the waste water in the waste water pool can easily cause "dirty blockage", not only the operation of the system is unstable, but also the equipment is easily damaged

In addition, the investment in building waste water storage pools is relatively large, and many bathing centers simply have no place to build them.

[0004] So far, there is still no technical device that works reliably and is suitable for heat recovery of waste hot water from showers in all bathing centers
