The energy consumption index of the blower muffler elevator (elevator) with Euler anti falling lifting system reaches 1.57wh. T.M, which is 50% of the energy consumption of the general container free elevator and is the current forced drive type (33% of the international building elevator). But it has not reached the ideal level of energy consumption, which is the negative power part of the elevator. The planned development of "Euler anti falling lifting integrated residential elevator (energy saving)" will recover negative power. The energy for negative work accounts for 1 / 3 of the total energy consumption, and 70% is planned to be recovered. The elevator (elevator) with a load of one ton and a speed of 0.7m/s now consumes 4kw of power, which is reduced to 3KW of actual power consumption. In the traditional production process of propellant and double base propellant, the primary support of the absorbed propellant, the secondary water drive of Roots blower muffler, drying and plasticizing are carried out in different processes and equipment. There are many sets of equipment, and the process interruption is high, which requires chain closure: water drive, drying, plasticizing and granulation are completed on the same equipment.
