Background technology
Fluid bed class drying equipment due to it is simple in construction, for ease of maintenaince, security is good the advantages of, in pharmacy, chemical industry, food
It is widely used etc. industry.Fluid bed class drier is to utilize high speed convection between air and material, with dried material
Effect, drying efficiency is high.In order to improve drying efficiency, it can also be set in drier and hot Jie is passed through in heat exchanger tube, heat exchanger tube
Matter (such as vapours), the tube wall heating of thermal medium exchange heat pipe, is heated with realizing to fluid bed inside.During traditional heat exchanger tube is
Blank pipe shape, thermal medium is passed through from one end of heat exchanger tube, now, and thermal medium is put down with being on the contact surface of tube wall (heat exchange layers)
Stream mode, causes to form very thick retention layer between thermal medium and tube wall, rate of heat exchange is relatively low.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art to be exchanged heat fluidized bed drying there is provided a kind of jet flow
Device, to solve the technical problem that traditional heat exchanger tube rate of heat exchange is low.
The utility model is achieved through the following technical solutions：
The utility model provides a kind of jet flow heat exchange fluidized bed dryer, including fluidized bed body, air blower, whirlwind point
From device and some heat exchanger tubes, the two ends of the fluidized bed body are respectively equipped with charge door and discharging opening, in its bed body provided with one laterally
Distribution grid and some longitudinal baffles, some dry cells are divided into by fluidized bed body, and each bottom for drying cell passes through airduct
Be connected with air blower, the heat exchanger tube is internally provided with the sleeve pipe of bilateral located at small interior is dried, one end of described sleeve pipe with it is outer
Gather passage on the steam raising plant connection in portion, its tube wall.
The fluidized bed body is divided into leading portion fluidised bed zones and back segment fluidised bed zones from charge door to discharging opening direction, often
The internally dry temperature that section fluidised bed zones are required is different, and requirement of the back segment fluid bed to temperature is higher than leading portion fluid bed, because
This, it is further preferred that the heat exchanger tube located at back segment fluidised bed zones is heat exchanger tube with well, the heat exchange of leading portion fluidised bed zones
In the case of pipe is common heat exchanger tube, heat medium temperature identical, the temperature that the tube wall of heat exchanger tube with well can reach will
Higher than common heat exchanger tube, the temperature requirements of fluidized bed body different zones can be met.
Further, the heat exchanger tube of back segment fluidised bed zones is the pipeline connected, back segment with the heat exchanger tube of leading portion fluidised bed zones
The heat exchanger tube of fluidised bed zones is heat exchanger tube with well, so, and thermal medium heats back segment fluidisation after the input of sleeve pipe entrance point, first
Bed area, this section has the tube wall temperature of the heat exchanger tube of sleeve pipe higher, and then thermal medium is directly entered after the output of cannula exit end
In the heat exchanger tube of leading portion fluidised bed zones, heat exchange, now, loss and heat exchange side because of heat are carried out with leading portion fluidised bed zones
The difference of formula, its temperature is substantially reduced.
The utility model has advantages below compared with prior art：The utility model provides a kind of jet flow heat exchange fluidisation
Sleeve pipe is provided with bed dryer, the heat exchanger tube of the fluidized bed dryer, thermal medium is first passed through in sleeve pipe, then by the passage of sleeve pipe
Spray into heat exchanger tube, so, thermal medium directly sprays to the inwall of heat exchanger tube in the form of jet flow, can break up retention layer, and raising is changed
Heat pipe and the rate of heat exchange in fluidized bed body, in the case of heat medium temperature identical, the temperature of the heat exchanger tube provided with sleeve pipe can
Apparently higher than the temperature of common heat exchanger tube, heating effect is improved.

Embodiment
Embodiment of the present utility model is elaborated below, the present embodiment using technical solutions of the utility model before
Put and implemented, give detailed embodiment and specific operating process, but protection domain of the present utility model is not limited
In following embodiments.
Embodiment 1
A kind of jet flow heat exchange fluidized bed dryer is present embodiments provided, with structure as Figure 1-3, including stream
Change bed body 1, air blower 2, cyclone separator 3 and some heat exchanger tubes 4, structure of the present utility model is carried out below in conjunction with the accompanying drawings detailed
It is thin to illustrate.
The two ends of the fluidized bed body 1 are respectively equipped with charge door 11 and discharging opening 12, and a cross direction profiles are provided with its bed body
Plate 13 and some longitudinal baffles 14, will be divided into some hothouses 15 in fluidized bed body 1, wherein, if positioned at the end of charge door 11
