Dalian to promote primary sewage source heat pump technology cooling and heating

Direct use of urban wastewater in low-grade energy used for heat in winter, cool in the summer and hot water preparation, current, energy-saving air-conditioning plant Dalian Hoko independent research and development of sewage source heat pump system has been running smoothly for nearly five months in the zone Friendship Shopping Center . Recently, the Municipal Economic Commission organized the application of primary sewage source heat pump technology promotion. Liaoning Provincial Department of Construction official said the original sewage source heat pump project in the province and even the country are the first of its kind.

According to reports, the system's initial investment and operating expenses savings rate of 20% or more. As a machine with three, eliminating the need for ordinary central air conditioning cooling towers , boiler room or heat exchanger room heat net and other initial investment; compared to water source heat pump, eliminating the need for drilling costs; compared to soil source pump, saving land and Investment costs.

Primary sewage source heat pump technology not only energy saving, but also environmental protection. Compared to large coal-fired boiler, the primary energy efficiency above 80%, the unit heating load power consumption than the ground water source to save 10% 50% 30% 60% saving operating costs than conventional central air conditioning system. Since the entire system does not require a cooling tower, there is no problem of water evaporation and flooding in summer operation, and more than 4,000 tons of water can be saved by 10,000 square meters. Furthermore, the energy per 1 ton of waste water can be reduced to 4.8 kg of carbon dioxide emissions, a large number of further reducing emissions sulfide, nitride. At the same time, completely solve the cooling tower or air-cooled cooler operating noise.

EDM Graphite

EDM graphite, also known as graphite block for EDM, is a new type of material, which is now more and more widely used in the precision mold processing industry. At present, in mold processing plants in developed European countries, more than 90% of mold processing electrode materials are graphite. Copper, the once dominant electrode material, has almost lost its advantages compared with graphite electrodes.

Our isostatic graphite and Molded Graphite were tested at the National Electrical Carbon Products Quality Supervision and Inspection Center. The main physical and chemical performance index as follows: the compressive strength--125 mpa, shore hardness -- 65 degrees, resistivity --12 mu Ω m. At the same time, the 10μm,8μm,6μm,4μm products have already began Large-scale production,.and unanimously acknowledged by customers. The 2μm,1μm graphite products are under trial. Our company high quality of isostatic pressing special graphite yield above 90%, far ahead of industry the yield of 70%, the first in the country.
