One Design background According to the changes in the industry, with the growing market for gas sales projects, we carry out research and development according to the requirements of post-processing equipment for gas sales projects. The air-cooled dryer is required to have low pressure drop, dew point of 2-10 ° C, and low energy consumption According to these three characteristics, we set the development route as a pre-cooler plus a three-in-one high-performance board converter plus a frequency conversion system to achieve the above requirements. The detailed details are described below. Two Theoretical basis Compressed air firstly enters the pre-cooler for cooling, then enters the three-in-one high-performance plate exchanger pre-cooling regenerator for secondary cooling, then enters the evaporation part for forced cooling and water diversion, and the treated low-temperature compressed air enters the pre-cooling regenerator to exchange heat with the entered hot air, so that the low-temperature compressed air is heated and flows out; The refrigeration system precisely controls the compressor speed according to the change of system load, and automatically adjusts the frequency to meet the processing requirements. Three Component description 1. The pre-cooler cools the compressed air with higher temperature. The pre-condenser is required to be small in size and high in heat exchange efficiency. Therefore, we adopt the plate-fin heat exchanger and the plate-fin heat exchanger, which are made of aluminum alloy and have high heat exchange efficiency. 2. High-performance three-in-one plate exchanger According to the design requirements, we have designed a special plate exchanger separately, which is characterized by low pressure loss, large heat exchange area, and the same processing capacity is more than 30% larger than that of ordinary three-in-one plate exchanger. 3. Frequency conversion system, the system program is specially adjusted for this model, featuring high precision, fast response, wide range of data reading, such as compressed air inlet temperature, outlet temperature, dew point temperature, compressed air pressure value, evaporation temperature, condenser temperature, suction temperature, evaporation pressure, condenser pressure, refrigerant exhaust temperature, the whole series of standard RS485 communication interface 4. Inverter compressor, in order to provide more stable operation of the equipment, we use Mitsubishi permanent magnet DC inverter compressor in the whole series. Mitsubishi DC inverter compressor runs smoothly, with wide frequency range and low noise. The internal rotor is treated with anti-wear coating, which can maintain stable output at ultra-high speed.

Air blow heat regeneration adsorption dryer with zero air consumption

• Others

I. Working principle The zero air consumption blast heat regeneration adsorption dryer is based on the low air consumption blast heat regeneration adsorption dryer, and a mid-mounted cooler is added. Ambient air sucked by the blower is heated by the heater to heat and desorb moisture from the adsorbent, hot air circulates through the intermediate cooler and the regeneration tower in the cooling stage, the regeneration tower is cooled through continuous closed circulation, and compressed air is not consumed in the whole regeneration process. II. Design Features 1. Communication can meet the user's requirements of RS-485 (standard configuration) and Internet of Things connection; 2. Self-developed EBZ200-2 multi-core driver, compared with the fixed cycle mode, can save more than 10% of the comprehensive energy consumption; 3. Dew point energy-saving control is selected, which can prolong the adsorption time and reduce the comprehensive energy consumption by more than 30% in the working condition of load fluctuation; 4. Customized high-performance adsorbent with 20% filling margin; 5, brand high-pressure blower, high-performance pneumatic valve, HTFS software design of high-efficiency cooler, reliable performance, long life; 6, 304 stainless steel control gas pipeline, specially designed shunt, high utilization rate of adsorbent, small gas pressure loss; 7, 7-inch Kunlun Tongtai touch screen programmable controller, dynamic monitoring of the operation process, signal acquisition including: air outlet temperature, heating temperature, regeneration tail gas temperature, A/B tower pressure, O blower pressure, dew point temperature (optional).
