Abstract

The invention discloses a series type mist spray and rotational flow combined drying device which comprises a drying tower, a cyclone separator, a cloth bag dust remover and a draught fan. The series type mist spray and rotational flow combined drying device further comprises a feeding system and an air feeding system and further comprises a rotational flow dryer. An inlet of the rotational flow dryer is connected with an air outlet and discharging port of the drying tower, and an outlet of the rotational flow dryer is connected with the cyclone separator, the cloth bag dust remover and the draught fan in sequence. In the series type mist spray and rotational flow combined drying device, the mist spray drying tower and the rotational flow dryer are used in combination so that energy consumption can be greatly reduced, and the average energy consumption can be reduced by around 25%. By means of the design of a pressure mist sprayer, materials can be better atomized, and thus the drying efficiency is further improved.

Description

Tandem spray cyclone combination drying device
Technical field
The present invention relates to a kind of tandem spray cyclone combination drying device, belong to drying equipment technical field.
Background technology
Spraying dry utilizes atomizer that material liquid is separated into fine drop, and carry out heat, mass transter with thermal medium and then obtain a kind of drying means of dry products, the advantages such as spraying dry has drying time short (several seconds to tens of second), temperature of charge is low, air intake scope is wide, many valuable but materials that is that not easily preserve are extended the shelf life greatly, make some materials be convenient to packaging, use and transport, all obtain extensive utilization in industries such as food, chemical industry, pharmacy at present.But spray-dired defect also clearly, and its energy consumption is too high, for the utilization rate of heat energy only about 30%, when hot blast temperature is low lower than volumetric heat transfer coefficient when 150 DEG C, evaporation intensity is little.Cyclone drying has the advantages that the time of staying is long, Mass and heat transfer intensity is large, the thermal efficiency is high, and two kinds of drying means respectively have quality.Current state inner drying industry is based on single drying mode, and energy use amount is large, is unfavorable for reducing costs protection of the environment.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of tandem spray cyclone combination drying device reducing energy consumption, improve dry materials degree is provided.
The technical solution used in the present invention is: a kind of tandem spray cyclone combination drying device, comprises drying tower, cyclone separator, sack cleaner, air-introduced machine, also comprise feed system and supply air system;
Described feed system comprises the hopper, agitating device, feeding engine and the compression sprayer that are connected successively by material pipe, and described compression sprayer is arranged at drying tower top, and described feed system passes through compression sprayer convey materials in drying tower;
Described supply air system comprises the air cleaner, air blast and the heater that are connected successively by pipeline;
Described drying tower comprises the air inlet being arranged at top of tower, and be arranged at the air-out discharging opening of bottom, air inlet is connected with heater;
Also comprise rotary flow desiccator, the import of described rotary flow desiccator is connected with the air-out discharging opening of drying tower, and the outlet of rotary flow desiccator is connected successively with cyclone separator, sack cleaner, air-introduced machine.
Further, described compression sprayer is made up of main body, tube connector and nozzle, nozzle is connected in main body by tube connector, described nozzle has 4, symmetrical between two, the position that the tube connector of relative nozzle is connected with main body is contour, staggers certain altitude in the position that the tube connector of adjacent nozzle is connected with main body.
In the present invention, spray drying tower and rotary flow desiccator are used in conjunction, and significantly can reduce energy consumption, average energy depletion few about 25%.The design of compression sprayer can make material better be atomized, and improves drying efficiency further.
Accompanying drawing explanation
Fig. 1 is the structural representation of tandem spray cyclone combination drying device of the present invention.
Fig. 2 is the structural representation of compression sprayer of the present invention.
Below in conjunction with drawings and Examples, the present invention is further illustrated.
