Detailed Description

The invention will now be further described with reference to the accompanying drawings, in which:

referring to fig. 1 to 3, a box type energy-saving dryer includes a main body 32, the top of which is connected to an inlet steam pipe 71 and an external steam pipe 102, and the bottom of which is connected to a high-temperature exhaust gas recovery pipe 14. Main part 32 one end is equipped with business turn over material door 11, it is used for feeding, the ejection of compact to go out material door 11, business turn over material door 11 and main part 32 sealing connection.

The main body is internally provided with a hot air fan 100, one side of the hot air fan is provided with a heat exchanger 101, one end of the heat exchanger 101 is communicated with the steam inlet pipeline 71 or 1O2, the other end of the heat exchanger is communicated with the heat exchanger, and the other end of the heat exchanger is communicated with the distilled water tank 33. In this embodiment, the heat exchanger 101 is a high-efficiency fin heat exchanger.

The inner cavity of the main body 32 is provided with a material rack 12 for placing materials to be dried.

As shown in fig. 3, the heat exchanger includes a heat radiation pipe 13 and a communication plate tube 9. The heat dissipation pipeline 13 is arranged in a winding mode, and the heat dissipation pipeline 13 is fixed in the main body through connecting the communicating plate pipe 9. So set up for high temperature steam can flow path is longer in heat dissipation pipeline 13, and the intensification efficiency is higher. Preferably, a single or a plurality of groups of heat exchanger sets are arranged in the main body according to different materials, and the heat exchanger sets are communicated with each other.

The apparatus further comprises a steam generating tank 92, said steam generating tank 92 being connected to the steam inlet conduit 71. The steam generating tank 92 is used to generate high-temperature steam.

The apparatus further comprises a distilled water tank 33. The distilled water pipeline 21 is connected with the high-temperature tail gas recovery pipe 14 at the bottom of the main body, and the distilled water tank 33 is connected with a water pump 34. The water pump 34 is used to pump the distilled water in the distilled water tank 33 to the outside.

The equipment also comprises a steam pressurizing and heating circulating device which comprises a steam circulating pipeline 62 and a steam compressor 61. The steam compressor 61 is connected with the high-temperature tail gas recovery pipe 14, one end of the steam circulation pipeline 62 is connected with a secondary steam outlet 63 arranged at the top of the main body, and the other end of the steam circulation pipeline is connected with a steam inlet pipeline 71 through the steam compressor 61. The steam compressor 61 is used for heating secondary steam generated after the materials are dried by the steam compressor 61 and pumping the secondary steam back to the pipe wall steam pipeline 13 or the heat exchanger 101; in the process, air and secondary steam in the inner cavity of the main body are sucked by the steam compressor 61, so that the inner cavity of the main body forms a negative pressure environment, the boiling point is relatively low in the negative pressure environment, the moisture is easier to evaporate, and the drying efficiency is higher.

Preferably, the high-temperature tail gas recovery pipe 14 is connected with the heat exchanger 101 and the distillation water tank 33, the high-temperature tail gas of the heat exchanger 101 and the distillation water tank 33 is recovered by the vapor compressor 61, the temperature of the high-temperature tail gas is raised, and the high-temperature tail gas flows into the heat exchanger 101 again, and the vapor continuously and circularly flows, so that the energy recycling is realized, and the drying energy consumption is reduced.

More preferably, the secondary steam outlet 63 is provided with a demister 64 for filtering in order to remove impurities in the secondary steam.

The working principle is as follows: before the equipment is operated, an operator can open the discharge door 11 to place materials on the material rack 12 in the main body 32 to be dried. The external steam enters the heat exchanger 101 in the main body through the steam inlet pipe 71 or through the heat exchange pipe 102. The heat exchanger 101 is filled with high-temperature steam, the heat exchanger is rapidly heated, and when the heat exchanger reaches the required temperature, the hot air fan 100 on one side of the heat exchanger rotates, so that flowing hot air is generated and blown to the material. The material with relatively low temperature is on the material frame 12, and the flowing hot air continuously transfers heat to the material, so that the temperature of the material is increased, the water in the material is evaporated, and the water content is reduced, thereby achieving the effect of high-temperature air drying.

In the process of drying the materials at high temperature, the high-temperature steam in the heat dissipation pipeline 13 of the heat exchanger performs an exothermic liquefaction reaction to form distilled water, and the distilled water flows into the distilled water tank 33 through the high-temperature tail gas recovery pipe 14. The distilled water is pumped to the outside of the apparatus by the operation of the water pump 34.

In addition, during the material drying process, as the moisture in the material is evaporated, secondary steam is formed and flows into the steam compressor 61 through the secondary steam outlet 63 and the steam circulation pipeline 62. The secondary steam rises in temperature under the action of the steam compressor, then flows into the heat exchanger 101 or the pipe wall steam pipeline 13, and then heats and dries the materials. So set up, not only reach the effect of cyclic recovery utilization, reduction mummification energy consumption, simultaneously because steam compressor 61 sucks air and secondary steam to main part 35 inner chamber, make the main part inner chamber form the negative pressure environment, the material is under the environment of negative pressure, and the boiling point is lower relatively, and moisture evaporates more easily, and mummification efficiency is higher.

High-temperature tail gas formed after heat exchange of high-temperature steam in the heat exchanger 101 flows into the high-temperature tail gas recovery pipe 14, and the high-temperature tail gas is compressed by the steam compressor to be heated up and then enters the heat exchanger 101 or the pipe wall steam pipeline 13 again because the high-temperature tail gas recovery pipe 14 is communicated with the steam compressor 61. So set up, the high temperature steam heat exchanger 101, pipe wall steam conduit 13, steam circulation pipeline 62 are interior incessantly circulation flow, and heat exchange efficiency is higher.

The equipment can dry the materials in a hot air drying mode, can also dry the materials statically in a high-temperature drying mode, meets different drying requirements of the materials, and has a wider application range; in addition, the drying operation can be normally operated only by a small amount of external steam, the temperature in the main body rises, secondary steam is generated in the material drying process, the secondary steam and the high-temperature tail gas of the distillation water tank can be recycled through the recovery and heating of the steam compressor, and the drying energy consumption is reduced.
