Embodiment Construction

[0016] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0017] As shown in Figures 1, 2, and 3, firstly, the control valve 13 is opened, and the water pump 3 is started to suck the water source from the direct-flow water source pipe network 1 through the direct-flow water source inlet pipeline 4 into the automatic water intake and decontamination device 2. It is removed, and then enters the vertical fluidized bed heat exchanger 6 through the water inlet pipeline. Before the direct-flow water source enters the heat exchange equipment, solid particles are added to strengthen the heat exchange capacity of the equipment and prevent the formation of dirt. In the vertical fluidized bed heat exchange A non-powered gravity sedimentation solid-liquid separator 7 is installed on the straight-line water source outlet of the device 6 to separate these homogeneous particles, and the s...

Abstract

The invention relates to a solid-liquid separation method for fluidized-bed heat exchanging technology, when straight flowing water source is distilled as low-level heat source (river, municipal wastewater, lake water, underground water, sea water and so on) or cooling water. The invention belongs to synthesis utilization technology area for natural energy source. It is characterized in that gravity subside solid-liquid separator with no power, down-comer tube, overflow tube, bottom component of down-comer tuber and vertical cycling fluidized-bed heat changer and so on are adopted to separate solid particle form straight flow water source entirely so that added consumption is not increased and it is achieved that the low-level energy source in the straight water source is used by adopting fluidized-bed heat exchanger technology. Benefit effects comprises that not increasing added consumption, solving plugging of heat exchanger by sewage and bad performance for heat exchanging thoroughly. It can be applied in industrial equipment with cool and heat supply or cooling by the straight water source. It is provided with obvious environmental protection benefit, social benefit and economical benefit.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of natural energy, and relates to a fluidized bed heat exchanger technology for extracting straight-through water sources (river water, urban sewage, lake water, groundwater, seawater, etc.) as low-level heat sources or cooling water. Separation method. Background technique [0002] The utilization of cold and heat sources of once-through water sources (river water, urban sewage, lake water, groundwater, sea water, etc.) will save the increasingly scarce fresh water resources, open up new fields for energy utilization, and provide a new way of thinking for the comprehensive utilization of water resources . The reason why these cold and heat sources are not used and popularized in a large area is mainly because their water quality is relatively poor. In actual operation, the water pumps and heat exchangers are often blocked by dirt. A patent, which uses an automatic backwashing ...
