Abstract
The utility model discloses a tail water drainage structure of a river-source heat pump. The tail water drainage structure is composed of at least two open drainage channels. The specific layout amount of the open drainage channels is set according to design flow; no cover is arranged at the top of each open drainage channel so that water drainage in surface flow manner is guaranteed; the space A, which is not smaller than 10m generally, is kept between each two open drainage channels; and the open drainage channels are arranged along the downstream direction and form included angles alpha ranging from 30 degrees to 60 degrees with the water flow direction generally. The tail water drainage structure is arranged uniquely and flexibly and capable of effectively controlling harmful effect of tail water of the river-source heat pump on receiving water body environments.
Description
Technical field
The utility model belongs to drainage works, environmental protection technical field, is specifically related to a kind of river source heat pump system tail water tapping equipment.
Background technology
River source heat pump is as a kind of novel refrigeration and heating mode, and is comparatively ripe on the angle of water source heat pump units technology.But in the process of utilizing water resource heat pump refrigeration in summer, winter heating,, thereby receiving water body temperature and state of ecological environment are impacted because the extraction of energy can bring the discharge water variation of temperature in the water.Though there is the scholar to recognize that river source heat pump large-scale application may pollute the receiving water body water environment, how to control possible pollution, have not yet to see the correlative study report.
Summary of the invention
Pollute the deficiency of control at existing river source heat pump system tail water, the purpose of this utility model is the typical feature according to the discharging of river source heat pump system tail water, on the basis of laboratory model experiment and numerical simulation experiment, a kind of river source heat pump system tail water discharge structure is provided, by the special arrangement mode of surface water channel, with the tail water that reaches control river source heat pump system dysgenic purpose to the receiving water body water environment.
The technical scheme that the utility model purpose realizes is as follows:
A kind of river source heat pump system tail water discharge structure, it is made up of the surface water channel more than two or two, and the concrete layout quantity of open channel is decided with design discharge, makes many mouthfuls of dischargings of tail water; Should keep a determining deviation A between surface water channel, generally be not less than 10 meters, to eliminate the temperature additive effect of tail water discharging; Surface water channel is designed to not add a cover, and promptly goes up to be uncovered structure, goes out stream to guarantee the tail water surface; The Parallel to the flow direction of the riverine water of surface water channel arranges, the angle a of the water (flow) direction of general and river is 30 ° to 60 °, flows out stream downstream with assurance tail water.
The utlity model has following characteristics:
1. river source heat pump system tail water discharge structure is on the basis of existing surface water channel, comes by the special development of arrangement form flexibly, and it is simple in structure, and design and construction are convenient.
2. the surface water channel of river source heat pump system tail water discharge structure adopts the design of not adding a cover, to adapt to the receiving water body SEA LEVEL VARIATION, guarantee the surface stream discharging of tail water, make discharging tail water fully contact, to reduce its harmful effect to the receiving water body water environment with air, receiving water body.
3. river source heat pump system tail water discharge structure surface water channel arrange along Parallel to the flow direction, be 30 ° to 60 ° angles with water (flow) direction, make the tail water of river source heat pump system to spread rapidly, thereby effectively control its harmful effect the receiving water body water environment by flowing of receiving water body.
4. keep between the surface water channel of river source heat pump system tail water discharge structure being not less than 10 meters spacing, stoped the mixing of each surface water channel tail water, thereby eliminated the additive effect of each surface water channel tail water discharging.
Description of drawings
Fig. 1: the plan view of river source heat pump system tail water discharge structure.
Fig. 2: the profile of river source heat pump system tail water discharge structure.
The specific embodiment
Referring to Fig. 1 and Fig. 2, to arrange that according to design discharge two surface water channels 1 are example, surface water channel 1 is designed to not add a cover, and goes out stream to guarantee the tail water surface.1 of surface water channel should keep a determining deviation A, generally is not less than 10 meters, to eliminate the additive effect of tail water discharging.The Parallel to the flow direction of surface water channel 1 riverine water 2 arranges that angle a general and water (flow) direction is 30 ° to 60 °, to guarantee that tail water flows out stream downstream.
Adopt this structure, the tail water of river source heat pump system enters receiving water body by surface water channel, and tail water adapts to the variation of receiving water body water level, for the surface goes out stream, it fully contacts with receiving water body with air, has strengthened the process of interchange of heat, thereby has reduced the adverse effect to the receiving water body water environment.Surface water channel arranges along Parallel to the flow direction, with water (flow) direction angle a be 30 ° to 60 °, tail water goes downstream, diffusion rapidly, thereby effectively controlled it to the receiving water body Effects of water environment.Kept being not less than 10 meters spacing A between surface water channel simultaneously, eliminated the additive effect of tail water discharging.
Important technological parameters:
Outfall place control flow velocity, 1m/s.
Structural parameters:
The surface water channel of river source heat pump system tail water tapping equipment is bed course based on brick with C10 concrete and rubble (brickbat), its specification (B+2C) * (H+t+0.1) * (B+2C+0.2):
