Abstract
A mechanical vapor recompression (MVR) evaporator fan air inlet pipeline comprises an air inlet pipeline body, wherein a water outlet channel is formed in the pipe wall at the bottom of the air inlet pipeline body, an annular water retaining ring is arranged along the edge of a channel opening of the water outlet channel and is close to the fan end, a water tank is arranged under the water outlet channel and covers the water outlet channel in a sealing mode, and a water draining pipeline is welded under the water tank. By utilizing the characteristic that water formed by steam condensation flows along the pipe wall at the pipe bottom, the water outlet channel is formed in the air inlet pipeline and provided with the water retaining ring for preventing the water from flowing away through a by-pass, fan shutdown caused by the fact that the water flows into a fan volute is effectively prevented, and the working efficiency of an evaporator is improved.
Description
Technical field
The utility model belongs to the evaporation equipment technical field, relates to a kind of MVR evaporator fan pipeline.
Background technique
In the industry such as chemical industry and food, medicine, some production process, such as: ammonium nitrate, caustic soda, sugaring and fresh water such as prepare at the production, usually need the dilute solution that is dissolved with solid solute concentrated, in order to obtain product or produce solvent.Industrial method commonly used is that these solution are heated to boiling, make wherein partial solvent vaporize and remove, and solid solute is normally nonvolatile, therefore can make dilute solution concentrated gradually, this process is evaporated exactly, and the capital equipment that is used for being evaporated is called vaporizer.A kind of vaporizer is arranged in vaporizer in the MVR vaporizer, the core component of this vaporizer is compression fan, and this blower fan is generally import.It is higher to service condition, in when operation, can not have during water enters the spiral case of blower fan, once there be water to enter spiral case, will trigger the alarm system of blower fan, and the alarm system one of blower fan starts, and blower fan will quit work.Blower fan has quit work, and whole evaporating system has just quit work, thereby has affected working efficiency.If volute of blower water inlet suddenly also can cause damage to draught fan impeller too much in addition, have much room for improvement.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of simple in structure, convenience of catchmenting, and effectively anti-sealing enters the MVR evaporator fan air intake pipe of blower fan.
Key problem in technology of the present utility model is: offered a rhone on the air intake pipe before blower fan, and water holding ring is set, if water is arranged to be carried secretly from the evaporation equipment of front, because the density of water is far longer than the density of water vapor, water can be walked by inwall below pipeline, water is through this drainage means the time, water will be caught by water holding ring, the water caught is imported the water tank of below by rhone, by drainage pipe, discharged, valve on drainage pipe is controlled opening and closing, thereby effectively anti-sealing enters the spiral case of blower fan, its concrete technological scheme is: MVR evaporator fan air intake pipe, comprise air intake pipe, it is characterized in that offering an effluent trough on the tube wall of described air intake pipe bottom, be provided with water holding ring along effluent trough notch edge, water holding ring is arranged at nearly blower fan end, described effluent trough below is provided with water tank, tank seal covers on effluent trough, be welded with drainage pipe under water tank.
As preferably, be welded with a valve on drainage pipe.
The beneficial effects of the utility model: the utility model utilizes the characteristic of steam condensation Cheng Shui along the trickling of pipe bottom tube wall, offer rhone on air intake pipe, and be provided with water holding ring, prevented that water is from the bypass runaway, effectively anti-sealing enters volute of blower and causes blower fan to stop, and has improved the working efficiency of vaporizer.
The accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
The left view that Fig. 2 is Fig. 1.
Embodiment
MVR evaporator fan air intake pipe, comprise air intake pipe 001, offer an effluent trough 011 on described air intake pipe 001 bottom tube wall, be provided with water holding ring 012 along effluent trough 011 notch edge, water holding ring 012 is arranged at nearly blower fan end, described effluent trough 011 below is provided with water tank 002, and water tank 002 sealing covers on effluent trough 011, and water tank is welded with drainage pipe 003 002 time.Be welded with a valve 004 on drainage pipe 003.
Claims (2)
