Steam compressor unit is mainly composed of compression system, water spray cooling system and lubrication system. The compression system is mainly composed of twin-screw steam compressor and its related steam pipe valves. Through a pair of mutually meshed spiral shaped male and female rotors in the cylinder, the compressor completes a complete suction compression exhaust process, so as to achieve the purpose of improving the steam temperature and pressure. The water spray cooling system is a specially designed nozzle, which is installed on the steam pipe to make it possible The lubricating system includes oil tank, oil cooler, oil filter and oil pump, which is responsible for lubrication, sealing and cooling of the unit.
Steam recompression technology is an efficient and energy-saving technology that compresses the secondary steam (low temperature and low pressure) in the evaporation process with a compressor, improves its temperature and pressure, and then uses it as a heat source to heat the materials that need to be evaporated, so as to achieve the purpose of recycling steam, that is, using a small amount of electric energy to obtain more heat energy and reducing the system's demand for external energy Widely used in food processing, chemical industry, paper industry, saltworks, pharmaceutical and other fields.
The steam inlet pressure of steam compressor unit is greater than 0.1MPa, and the maximum outlet pressure is 2.0MPa.
50 ~ 70 ℃ hot water solution.
The solution of ammonia heat recovery system is to recover the cold and heat supply of the refrigeration system without affecting the normal operation of the refrigeration system, and provide hot water after treatment by the heat recovery system. The heat recovery system completely absorbs the condensation heat of the refrigeration system, and truly realizes zero waste heat emission of the system, which is conducive to the sustainable development of the environment. At the same time, the perfect ratio of the refrigeration system and heat recovery system improves the performance of the system and ensures a high comprehensive energy saving coefficient. The ammonia heat pump system adopts an integrated structure, which can achieve simultaneous cooling and heating after optimizing the original system Purpose. The system has the advantages of simple transformation, low cost, small floor area, convenient operation and maintenance, and can be applied to all ammonia refrigeration systems without boiler and electric heating equipment set for hot water.
Heat pump system: r124 is used as the working medium of heat pump, and the low-temperature heat source is the compressor exhaust of the original refrigeration system. From the refrigeration system exhaust, part of the exhaust gas flows into the condensing evaporator of the heat pump unit for condensation, and the condensed ammonia liquid is throttled to the ammonia low-pressure refrigeration system. The evaporation side of the condensing evaporator is the working medium of heat pump. After absorbing the condensation heat of ammonia, the working medium of heat pump evaporates into gas, which is inhaled and compressed by the heat pump compressor. The high-temperature exhaust gas of the heat pump compressor enters the heat pump condenser for condensation. After the economizer, it expands and throttles to the condensing evaporator for evaporation, and circulates repeatedly.
Hot water system: the 80 ℃ return water enters the heat pump condenser and is heated to 85 ℃ and supplied to the heating process.
Heat and cold dual effect heat pump unit provides heat and cold energy at the same time, with high comprehensive energy efficiency ratio. Realize the double effect utilization of energy.
