Device for simulating water temperature laying of lakes and reservoirs on basis of natural heat transfer

Abstract

The invention discloses a device for simulating water temperature laying of lakes and reservoirs on the basis of natural heat transfer. The device comprises a model reservoir, a main air-conditioning unit, a plurality of annular condensation pipes, a temperature sensor and a plurality of temperature probes. The annular condensation pipes are uniformly arranged on a bottom layer of the model reservoir from top to bottom, and the main air-conditioning unit is used for refrigerating water on the bottom layer of the model reservoir by the aid of the various annular condensation pipes which are connected with the main air-conditioning unit; the temperature sensor is connected with the main air-conditioning unit and is used for measuring the temperature of the water on the bottom layer of the model reservoir, so that the main air-conditioning unit can be started or stopped under the automatic control of the temperature sensor; the temperature probes are respectively arranged in the water on the bottom layer of the model reservoir and are used for checking the temperature uniformity of water on an isothermal layer in later refrigerating periods. The method for simulating water temperature laying of the lakes and the reservoirs on the basis of natural heat transfer has the advantages that the layered water formed by the aid of the device is vertically and stably layered, the temperature of the water on the same horizontal plane is uniform, the device is high in refrigerating speed, low in energy consumption and convenient to implement and is simple, flow fields of the water are free of interference of temperature control components, and the like.

Description

【Technical field】 [0001] The invention belongs to the field of water quality pollution control of lakes and reservoirs, and relates to the pilot test research of layered lakes and reservoirs, in particular to a reservoir water temperature layering simulation device based on natural heat transfer. 【Background technique】 [0002] The water body temperature of deep-water lakes and reservoirs has obvious seasonal characteristics of layered distribution along the depth. Generally, in summer, a typical water temperature layered structure of variable temperature layer, thermocline layer and isothermal layer is formed from top to bottom. The water temperature gradually decreases and the density gradually increases. The temperature gradient in the thermocline can be as high as 0.7°C / m in summer. In the bottom water of stratified lakes and reservoirs, dissolved oxygen cannot be replenished due to the buoyancy resistance of the thermocline, and various microorganisms and chemical effec...
