Abstract
The utility model relates to a mechanical secondary steam circulating compressor, wherein, a motor and a transmission mechanism are disposed on a rack, a spiral case is connected at one end of the rack, an impeller is disposed in the spiral case, the impeller is connected with an extending end of a main shaft of the transmission mechanism, and a seal disc is arranged at the outside of the spiral case; and a steam inlet is arranged on the side wall of the spiral case, and a steam outlet is arranged at the top part of the spiral case. The compressor increases the steam pressure relying on the change of kinetic energy, thereby having reasonable structure and low failure rate, reducing the economic loss caused by breakdown maintenance, and guaranteeing normal production, therefore, the utility model is the practical mechanical secondary steam circulating compressor.
Description
Technical field
The utility model relates to a kind of mechanical type secondary steam recycle compressor.
Background technique
Mechanical steam compression cycle vaporizer is the novel high-efficiency and energy-saving evaporation equipment that the twentieth century end develops, its working principle is that the secondary steam that produces of vaporizer is after the vapour compression machine effect, temperature can improve 7～8 ℃, return the heating thermal source that serves as vaporizer again, to substitute the employed most living steam of evaporation equipment, make living steam only as replenishing of thermal loss and replenishing of the required heat content of the charging and discharging temperature difference, significantly reduce the living steam consumption of vaporizer thus, realize the purpose of environmental protection and energy saving.Employed recycle unit is exactly a mechanical type secondary steam recycle compressor in this mechanical steam compression cycle evaporation equipment, and this is the key that guarantees that evaporation equipment can proper functioning.But the structure of prior mechanical secondary steam recycle compressor is unreasonable, and rate of fault is higher, influences ordinary production.
The model utility content
The purpose of this utility model just provides a kind of mechanical type secondary steam recycle compressor that reduces rate of fault, to reduce manufacturing enterprise because of economic loss that shutdown maintenance was caused.
The utility model is achieved in that a kind of mechanical type secondary steam recycle compressor, motor and driving mechanism are housed on frame, spiral case are arranged, impeller is housed in spiral case in frame one termination, the inserting end of the main shaft of described impeller and described driving mechanism joins, and is provided with seal disc in the spiral case outside; On the sidewall of described spiral case, have steam inlet, have steam ouput at described spiral case top.
When motor rotates the impeller high speed rotating, in the middle of impeller, formed certain negative pressure, like this, used steam just enters in the spiral case that is negative pressure by connecting pipeline in vaporizer.Impeller drives the steam high speed rotating that enters in the spiral case, and constantly steam is thrown away under action of centrifugal force, makes the volume compression of steam, and flow velocity increases, and makes that thus steam is converted to static energy to kinetic energy at the volley; Along with improving constantly of vapor pressure, the static energy of steam is converted into kinetic energy again, and returns by steam ouput on the spiral case and connecting pipeline and to enter in the evaporation equipment, forms the steam of double heating, is recycled in the evaporator operation system.
On the inserting end of described main shaft, be coated with anticorrosive coat.So just can reduce the corrosion of steam effectively, reduce fault and loss, reduce maintenance load main shaft.
The input shaft of described driving mechanism and the output shaft of described motor link by elastic coupling flexible coupling.This elastic coupling flexible coupling except that having quite high transmission efficiency, a small amount of off-centre when also buffer shaft connects effectively, prolonged working life.
Be provided with guard shield in described elastic coupling flexible coupling outside, with protection operator's personal safety.
The utility model is not that the mode of utilizing cylinder volume to reduce improves vapor pressure; but rely on the variation of kinetic energy to improve vapor pressure; therefore; it is rational in infrastructure; at the bottom of the rate of fault; reduced the economic loss that shutdown maintenance caused, guaranteed ordinary production, thereby be a kind of practical mechanical type secondary steam recycle compressor that is suitable for.
