Description

A kind of atomizing drier

Technical field

The utility model belongs to drier technical field, and in particular to a kind of atomizing drier.

Background technology

Spray dryer is that solution, slurries or suspension are formed misty fine droplets by sprayer and are scattered in thermal current In, make moisture rapid vaporization and achievees the purpose that dry.The contacts sides such as cocurrent, adverse current or mixed flow can be used with material in thermal current Formula.This drying means need not carry out raw material in advance mechanically decoupled, and drying time is very short (generally 5~30s), therefore It is suitable for the drying of heat sensitive material, such as food, drug, biological products, dyestuff, plastics and chemical fertilizer.

The advantages of spray drying is that rate of drying is fast, the time is short, is particularly suitable for the drying of heat sensitive material；It can continuously grasp Make, product quality is stablized；Non-dusting in drying process, working condition are preferable；Other methods are difficult to be dried Low concentration solution is not required to that dry products can be directly obtained by feed liquid through operations such as evaporation, crystallization, mechanically decoupled and crushing.It lacks Point is that the volume of required drier is big；Unit product heat consumption is big and power consumption is big.

As shown in Figure 1, atomizing drier in the prior art, including drying cylinder 1, sprayer 2, plunger pump 3, wet feed device 4, cyclone separator 5, air heater 6, air outlet slit 7 and dry material outlet 8；Wherein drying cylinder 1 is inverted conical, drying cylinder 1 upper end is equipped with input port, and lower end and middle part are equipped with delivery outlet, input port and sprayer 2, plunger pump 3 and the wet feed of drying cylinder Device 4 is connected, and in addition 2 side of sprayer is also connected with air heater 6；Wet stock adding by plunger pump 3 in wet feed device 4 The wet stock of pressure and then high pressure passes through sprayer 2 so that liquid wet stock is converted into misty particulate, air shape after heater At thermal current, misty particulate encounters thermal current, the wet stock of wink-dry mist particulate.

Drying cylinder lower end is connected with the delivery outlet at middle part respectively at cyclone separator 5, and 5 upper end of cyclone separator goes out with air Mouth 7 is connected, and lower end is connected with dry material outlet 8.

In the prior art, air heater 6 is generally located on ground i.e. the lower end of drying cylinder 1, with drying cylinder 1 The sprayer 2 at end connects, and intermediate pipeline is very long, and pipeline is long to be bound to cause scattering and disappearing for heat, causes to waste；In addition atomizing The drying feature of drier is to meet wet misty fine moment and the air-flow of heat, and moment completes drying, and rate of drying is fast While thermal energy utilization rate decline, it is dry after remaining air also carry certain heat, such air is directly discharged Also result in the waste of thermal energy.

Utility model content

Purpose of utility model：In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of structure letter It is single, can solve the big technical problem of traditional spray formula drier heat energy loss with the atomizing drier of recycling heat energy.

Technical solution：In order to realize that above-mentioned purpose of utility model, the technical solution adopted in the utility model are as follows：

A kind of atomizing drier, including the heating of drying cylinder, sprayer, plunger pump, wet feed device, cyclone separator, air Device, air outlet slit and dry material outlet；The upper end of drying cylinder is equipped with input port, and lower end and middle part are equipped with delivery outlet, wet feed device, column The input port of plug pump, sprayer and drying cylinder is sequentially connected；Sprayer side is also connected with air heater；Drying cylinder lower end It is connected respectively at cyclone separator with the delivery outlet at middle part, cyclone separator upper end is connected with air outlet slit, lower end and dry material Outlet is connected；Air heater be mounted on drying cylinder top and be located at air outlet slit side, in addition air heater also with sky Gas outlet connection.

Preferably, air heater is respectively first entrance and second entrance equipped with two entrances, first entrance with it is outer Boundary communicates, and second entrance is connected with air outlet slit.

Air filter is installed as between preferred air outlet slit and air heater.

Preferably, drying cylinder is inverted conical.

Advantageous effect：Compared with prior art, the utility model has the following advantages：Air heater is disposed over Position not only shortens the length of pipeline between sprayer and air heater in this way, reduces thermal current in pipeline transportation Heat energy loss, and the air heater and the air outlet slit that change installation site are connected closer to and with air outlet slit, The air-flow with heat of discharge can be recycled, further save thermal energy, reduce loss and recycled, two Aspect is started with, energy saving, reduces cost.

Specific implementation mode

In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, embodiment is with the utility model skill Implemented under premised on art scheme, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this practicality Novel range.

As shown in Fig. 2, a kind of atomizing drier, including drying cylinder 21, sprayer 22, plunger pump 23, wet feed device 24, rotation Wind separator 25, air heater 26, air outlet slit 27 and dry material outlet 28；The upper end of drying cylinder 21 is equipped with input port, under End and middle part are equipped with delivery outlet, wet feed device 24, plunger pump 23, sprayer 22 and drying cylinder 21 input port be sequentially connected；Spraying 22 side of device is also connected with air heater 26；The delivery outlet at 21 lower end of drying cylinder and middle part is respectively at 25 phase of cyclone separator Even, 25 upper end of cyclone separator is connected with air outlet slit 27, and lower end is connected with dry material outlet 28, and air heater 26 is mounted on The top of drying cylinder 21 is simultaneously located at 27 side of air outlet slit, and in addition air heater 26 is also connect with air outlet slit 27.So not The length for only shortening pipeline between the 26 of sprayer 22 and air heater, reduces thermal energy damage of the thermal current in pipeline transportation Consumption, and the air heater 26 and the air outlet slit 27 that change installation site are connected closer to and with air outlet slit 27, it can It is recycled with the air-flow with heat to discharge, further saves thermal energy, reduce loss and recycled, two sides Face is started with, energy saving, reduces cost.

Air heater 26 is respectively first entrance 29 and second entrance 30 equipped with two entrances, first entrance 29 with it is extraneous It communicates, heats external air, second entrance 30 is connected with air outlet slit 27, thus can be from air is introduced on both side, completely The demand of sufficient thermal current.

Air filter 31 is installed, air filter 31 can filter out between air outlet slit 27 and air heater 26 The impurity such as the dried material in the air of discharge so that the air for entering air heater is purer.

Wherein drying cylinder 21 be inverted conical, structure up big and down small in this way, upper space can allow greatly misty particulate and Thermal current has enough space exchanging dryings, the small volume for reducing drying cylinder of lower space to reduce the loss of thermal energy.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the scope of protection of the utility model.
