Abstract

The invention relates to a wastewater energy utilization device for high-rise buildings, which mainly solves the problems that the water flow is small and discontinuous, the energy utilization efficiency is low, and the equipment is extremely complicated and is difficult to popularize in the prior art. The potential energy of dispersed and discontinuous high-rise domestic wastewater is converted into concentrated and continuous electric energy, and the partial power demands of the high-rise buildings are met. The wastewater energy utilization device consists of a solid-liquid separation device, a partition water storage device, a water level automatic control quick-opening device and a power generation device. The technical scheme of partitioned water storage and power generation is adopted, the energy consumption caused by a small amount of water flows down along the pipe walls of drain pipes only is prevented, and the dispersed and discontinuous drainage of a small amount of domestic wastewater is converted into concentrated and continuous drainage of a great amount of domestic wastewater. The spring magnetic water level automatic control device is used for quickly and automatically opening a water valve and reducing the energy loss in the process that the water valve is opened or closed. Compared with the conventional wastewater energy utilization device, the wastewater energy utilization device improves the utilization rate of the energy of the wastewater.

Description

A kind of tall building waste water energy utilized device

Technical field:

The present invention relates to a kind of tall building waste water energy utilized device, belong to environmental protection, field of energy-saving technology.

Background technique:

Resident living water is high and the residential building building is increasingly high, and sanitary wastewater flows down from tall building has comparatively considerable energy.Sanitary wastewater utilization at present mainly is that architectural intermediate water utilization and city focus on reuse, and it all be unable to do without the consumption of electric energy in realizing the water saving process; Existing waste water energy use technology such as waste water electricity generating device, its technical characterstic are the sanitary wastewater generatings that directly utilizes each household to collect at each household waste pipe place, and it is little that this technology exists current; Discontinuous; Energy utilization efficiency is low, and equipment is too complicated, the problem that is difficult to promote.This tall building waste water energy utilized device is simple in structure, cheap, dispersion is interrupted waste water potential energy is converted into concentrated continuous electric energy, and energy conversion efficiency is high, energy-conserving and environment-protective.

Summary of the invention:

The present invention relates to a kind of tall building waste water energy utilized device; It is little mainly to solve the current that exist in the existing technology, discontinuous, and energy utilization efficiency is low; Equipment is too complicated; The problem that is difficult to promote is converted into concentrated continuous electric energy with the high building sanitary wastewater potential energy that disperses to be interrupted, and satisfies the part electricity consumption needs of tall building.The present invention by equipment for separating liquid from solid, subregion water-storing device, water level control quick-opening device automatically, electricity generating device is formed.For solving the problem that exists in the above-mentioned existing technology; Taked to divide the technological scheme of section reservoir impoundment power generation; Water-storing device is made up of several sectional wet pits and main drainpipe, guarantees to be full of water all the time in the water main through water level automatic control device, forms high head; Avoided water in a small amount to flow down the energy loss that causes, realized the dispensed in small quantity intermittent discharge of sanitary wastewater is converted into a large amount of continuous blow-downs of concentrating along the waste pipe tube wall.Solid impurity in the equipment for separating liquid from solid filtered wastewater avoids main drainpipe to stop up.When wet pit reaches the height of water level of setting, open water valve apace automatically by spring magnetic-type water level automatic control device, the high head waste water that in wet pit, stores promotes hydraulic turbine generator and continues generating through the main drainpipe discharging.Low during to the minimum that sets at the water level of wet pit, spring magnetic-type water level automatic control switch is automatic-closing valve apace, restarts retaining, entering next round reservoir impoundment power generation process.

Because the present invention discharges the dispersion discontinuity of sanitary wastewater and is converted into concentrated continuous blow-down through different floors being carried out branch section design water-storing device, utilizes electricity generating device with respect to existing waste water energy, has improved the waste water energy utilization ratio; Adopt spring magnetic-type water level to control fast-switching arrangement automatically, dispense with outer connecting power can be realized the snap switch action of water valve, has reduced the energy loss that water valve causes in the process of switch, and capacity usage ratio is improved.

Embodiment:

Below in conjunction with accompanying drawing the present invention is done further description.

Like Fig. 1, Fig. 2 and shown in Figure 3; Tall building waste water energy utilized device among the present invention, it is made up of equipment for separating liquid from solid (1,2), branch section water-storing device (3,4), water level automatic control switch device (5,6,7,8,9,10,13), water turbine (11), water valve (12), a waste pipe (14), impurity-discharging pipe (15), main drain (16).The sanitary wastewater that tall building is every layer gets into water-storing device through a waste pipe (14) from the each household drain opening, and through filter (1) filtering solid sundries, solid sundries enters sewerage by waste pipe (16); Waste water then gets into wet pit (3) beginning retaining, and ball float (5) raises with the water level of wet pit (3), and connected boosting lever (6) stretches through backguy (13) around fulcrum (7) and holds power spring (8); The tension force of spring (8) increases gradually, and when the tension force of spring (8) during greater than the suction of magnet (10), spring (8) is retraction fast; Pulling water valve fork (9) quick rotation; The spool of water valve (12) is opened rapidly under the drive of water valve fork (9), and the waste water in the wet pit (3) begins to discharge, behind main drainpipe (4) and little incrustation pond (2) and water valve (12); Arrive water turbine (11), promote water turbine (11) generating of starting working.Flow into impurity-discharging pipe (15) through the waste water after the generating, the solid sundries under the row of washing out gets into main drain (16).When the water level of wet pit (3) low during to the minimum that sets; Hold the suction of the tension force of power spring (8) less than magnet (10); Water valve fork (9) is drop-down fast by the magnetic force of magnet (10), and water valve cuts out, and the waste water in the wet pit (3) stops to flow out; Generator suspends generating, restarts the reservoir impoundment power generation of next round.
