To achieve non-blocking continuous heat transfer is the city's primary sewage and rivers and lakes seawater as a heat pump cold, heat the key technology. Beijing Ruiboli Thermal Energy Technology Co., Ltd. independent research and development of "primary sewage source heat pump air-conditioning system complete sets of technologies" to successfully solve the bad water on the heat transfer equipment and pipeline congestion and pollution of this world technical problems, so that the large-scale application of raw sewage As a heat pump cold source become a reality. The technology was identified by the National Science and Technology Appraisal Committee as "the international advanced level of technology." Primary Antibacterial Source of Sewage Source Usage: The heat exchanger in the primary sewage heat pump heating air-conditioning system is non-clogging heat exchanger, so that the heat pump unit can continuously collect and release the heat energy from the primary sewage through the heat exchanger for a long time. ZNWFJ-â… â…¡, â…¢-50100,200 The first group: ZNWFJ said the sewage heat pump anti-stop Hanyu Pinyin abbreviation. Group II: Roman letters I, II or III, indicating the type of effluent to be used. Class I sewage refers to domestic sewage in urban sewers or other industrial wastewater containing a large amount of suspended solids but excluding other sewage containing strong chemical corrosion; Class â…¡ refers to untreated river, river and lake water; â…¢ Sewage refers to seawater. Product Features: Collecting raw sewage Sewage solids above the specified size, suspension of suspended matter, allowing the solids below the size of the suspended solids into the sewage without heat exchanger plugged, heat transfer of sewage back to the sewage resistance machine Another channel, together with the interception of contaminants back to the sewage trunk. Technical Principle: The principle of the filter surface rotation, at any time there are some filter surface is located in the filter work area, the other part of the filter surface located in the water recoil zone. Within a week of rotation, each filter has a portion of its time in the filtered work area to perform the filtering function while the other is backwashed in the backwash area to resume the filtering function. Sewage through the filter to the heat exchange equipment without clogging heat transfer, the heat of the sewage back to the sewage anti-collision zone recoil area of ​​the filter surface to implement recoil, and all the recoil away from the debris and all the way back to the sewage Main canal.
