Description
Technical field
Tubular heat exchanger descalling technique is the utility model is related to, more particularly to a kind of online machinery of tubular heat exchanger removes
Dirty device.
Background technology
Tubular heat exchanger is a kind of effective energy transfer heat transfer instrument at present, is widely applied in many industries, example
Such as tubular type evaporation, condenser, radiator.Horizontal tube MVR (Mechanical Vapor Recompression machineries in recent years
Vapor recompression) vapo(u)rization system more with its energy-conserving and environment-protective it is with the obvious advantage and high salt water process, percolate processing etc. emerging industry
Promoted.And it is also highlighted in new industry scale problems, such as percolate, its complicated component, organic and inorganic knot
Dirty thing is a lot, causes evaporation equipment must frequent shutdown cleaning.The present apparatus is adopted for lying pipe spray cloth film evaporator scaling mechanism
Mechanically, realize online removing fouling and suppress fouling function.
Because can not intuitively understand fouled condition, horizontal-type evaporator tube layer fouling is extremely hard to clean, even if making after shutting down
Rinsed with chemical cleaning solution, due to being sprayed dead angle, it is also difficult to ensure that cleaning is thorough.When fouling is serious, because
Film heat-transfer surface adds one layer of fouling, seriously reduces the heat exchange efficiency of heat exchanger tube, and evaporation process will expend more energy
Amount.
After usual evaporator shell fouling, evaporator must be stopped, using chemical cleaning medicament circulation flushing shell
Surface, dissolve its surface scale；When foulant can not be completely dissolved using chemical agent, or when heat exchanger tube and heat exchanger tube
Between fouling connected, when blocking medicament flow channel, it is necessary to open equipment, washed using giant or manual machinery
Brush, scavenging period are considerably long.
The process of fouling is also not accomplished in one move, and organic matter or inorganic salts are also to be stepped up in the thickness of shell fouling
, if removing these foulings in time during evaporation, or suppress fouling, can thus avoid frequent Chemical cleaning
Or giant cleaning.According to this thinking, drive tube brush to come and go using mechanical mechanism and scrubbed in shell, prevent the richness of fouling
Collection, while interbank fouling can be avoided to put up a bridge completely.Tube brush is made up of high temperature resistant nylon silk, and scrub process does not influence Horizental showering
Liquid distribution system, and be advantageous to cloth film uniformly and reduce evaporation film thickness.
