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
The present invention relates to the extraction of bath center shower spent hot water heat energy and recycle device once more, belong to heat energy that utilizes in the heat exchanger replacement extraction shower waste and the energy recovery recycle utilization device of heating for new water.
Background technology
Because the shower spent hot water of bath center is contained a large amount of unclean materials, because the unstable heat energy that reclaims wherein of giving of flow and water temperature has brought heavy technology barrier, people have to the spent hot water after the shower is emitted fully now simultaneously.Because how much heat energy human body does not absorb in the shower process, the water temperature that emits still more than 36 ℃, emits the hot water more than 36 ℃ in vain, has caused a kind of a large amount of waste of heat energy.
To this, the technical scheme that has attempts to build a wastewater disposal basin, and waste water is stored, and extracts heat energy wherein with heat exchanger and water resource heat pump again.But the waste water in the wastewater disposal basin is easy to cause " dirty stifled ", the fluctuation of service of system not only, and be easy to damage equipment.In addition, the storage pool investment of building waste water is bigger, and a lot of bath centers are basic just to be built nowhere.
Up to the present, still there is not a kind of reliable technique device that is fit to all bath center shower spent hot water energy recovery.
Summary of the invention
The objective of the invention is to avoid above-mentioned weak point of the prior art and a kind of reliable technique device that is fit to all bath center shower spent hot water energy recovery simple in structure is provided.
The present invention can reach through following measure: human body stands on the dividing plate during shower, and the spent hot water of shower is leaked down to a drip tray heat exchanger from dividing plate, is heat exchanger plates (corrosion resistant plate or aluminium sheet) above the drip tray, is heat exchanger tube below.Running water arrives reservoir via the heat exchanger tube and the shower waste reverse flow of heat exchanger.When shower, open earlier the warm water valve, do not open hot-water valve again, make water temperature rise to the temperature that shower needs when the water temperature of shower reaches when requiring.The warm water valve of shower and running water inlet valve are taked synchronous equivalent control, and the running water inlet valve is opened automatically when opening the warm water valve, and the warm water of from reservoir, emitting gets into reservoir by the running water of equivalent after heat exchange.The mixing water of this system (adjusting of shower water temperature) process is the mixed process of warm water and hot water, has cancelled the mixed process of original cold water (running water) and hot water, has reduced the use amount of hot water, thereby has reached the purpose of energy recovery recycle.
Like heat transfer temperature difference is 5 ℃, and so, the water temperature after heat exchange in the reservoir is 35 ℃, and the temperature of spent hot water discharging is 20 ℃ (water temperature of at present supposing running water is that 15 ℃, the temperature of shower waste are 40 ℃, and the water temperature in the boiler is 50 ℃).
The present invention compared with prior art has following significantly technique effect:
1. needn't build a waste water storage pool again, it has reduced investment of devices, makes the adaptability of equipment wider.
2. avoided the difficulty of " dirty stifled " and overhaul of the equipments.Running water is walked in the Tube Sheet of Heat Exchanger, and waste water is walked on the heat exchanger plates, opens dividing plate at ordinary times and can clear up heat exchanger plates at any time.
3. system is high to the utilization rate of used heat, can reach 80%. to the utilization rate of used heat
The temperature of at present supposing running water is 15 ℃, and the water temperature of shower waste is 40 ℃, and the water temperature of waste discharge is 20 ℃.
The heat energy of the water that the original system discharging is 1 ton 40 ℃ is (40-15) * 1000=25000 kilocalorie.
The heat energy of the water that the native system discharging is 1 ton 20 ℃ is (20-15) * 1000=5000 kilocalorie, and the heat energy of recovery is the 25000-5000=20000 kilocalorie, and the rate of recovery is 20000/25000=80%.
