Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fungus solid-state fermentation, in particular to a water vapor and dust separation device disposed after low-temperature drying equipment. Background Art
[0002] The solid-state fermentation products of fungi are rich in biologically active substances. In order to retain the biological activity of the fermented materials during drying, a low-temperature drying device is usually used to remove the moisture contained in the materials. The air discharged by the low-temperature drying device when drying the materials contains a large amount of water vapor and dust. From an environmental protection perspective, this part of water vapor and dust must be purified before being discharged into the atmosphere. If it passes directly through a pulse dust collector during purification, the water vapor and dust will quickly clog the bags of the pulse dust collector, and it will be difficult to clean the bags.
[0003] In the prior art, this part of air full of water vapor and dust is usually heated to above 180°C and then passed through a pulse dust collector to achieve the purpose of separating water vapor and dust. However, when the fungal solid fermentation product is dried, the dust contains a large amount of high-value spore powder. While separating water vapor and dust by high temperature, the spore powder will also be inactivated, damaging the value of the spore powder. Therefore, a device is needed that can separate water vapor and dust at low temperature. On the one hand, it can maintain the active value of fungal spore powder, and on the other hand, it can reduce the risk of clogging of bag dust collectors and achieve an ideal dust removal effect.

[0019] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.
[0020] according to Figure 1-5 As shown, a post-water vapor and dust separation device for low-temperature drying equipment includes a box body 1, an air guide assembly is arranged inside the box body 1, the air guide assembly includes a plurality of groups of condensation plates 2 and wind shields 3, the condensation plates 2 and the wind shields 3 are in a relatively parallel structure, the wind shields 3 are obliquely installed on the inner wall of the box body 1, a liquid collecting pool 11 is provided at the bottom of the box body 1, an air inlet 13 is opened at the top of the box body 1, and an air outlet 14 is opened at the lower end of the right side wall of the box body 1.
[0021] In this embodiment, the wind shields 3 are installed at intervals on the left and right inner walls of the box body 1, and the wind shields 3 form an angle of 45° with the side walls of the box body 1. A plurality of groups of external plug-in plate grooves 15 are opened on the left and right outer walls of the box body 1. The condensation plate 2 is installed in the external plug-in plate grooves 15 by bolts. The condensation plate 2 is externally connected to the refrigeration pipe of the compressor. The two ends of the condensation plate 2 abut against the ends of the adjacent wind shields 3. A closed air guide path is formed by the wind shields 3 and the condensation plates 2 on the left and right sides of the box body 1. When the air containing water vapor and dust hits the condensation plate 2, the water vapor in the air condenses into water.
[0022] In this embodiment, the bottom end of the condensation plate 2 installed on the left side wall of the box body 1 is aligned with the top end of the condensation plate 2 installed on the right side wall of the box body 1, thereby providing the maximum circulation space for air and ensuring the circulation rate of air.
[0023] In this embodiment, a guide groove 21 is provided at one end of the condensation plate 2 close to the middle of the box body 1, and a groove 16 corresponding to the guide groove 21 is opened on the front and rear inner walls of the box body 1. The water condensed on the condensation plate 2 flows along the guide groove 21 into the groove 16.
[0024] In this embodiment, the liquid collecting pool 11 is a bucket-shaped structure that is wide at the top and narrow at the bottom. A sewage outlet 12 is provided at the lower end of the liquid collecting pool 11. Condensed water mixed with some dust flows into the liquid collecting pool 11 along the groove 16 for collection. The sewage outlet 12 is connected to the solid-liquid separator, and further separation is achieved through the liquid-solid separation device. The solid part contains a large amount of high-value spore powder, which can be further dried by low-temperature drying before use.
[0025] In this embodiment, a water baffle 4 is provided between the liquid collecting pool 11 and the air outlet 14. The water baffle 4 is fixedly mounted on the inner wall of the box body 1. The liquid collecting pool 11 and the air outlet 14 are relatively separated by the water baffle 4 to prevent the lower low-temperature water vapor from being sucked out of the air outlet 14 by the negative pressure air.
[0026] When the utility model is in use, the air outlet 14 is connected to the cyclone dust collector, and the cyclone dust collector provides an air power source. The air inlet 13 is connected to the exhaust port of the low-temperature drying device. The wind containing water vapor and fine dust discharged by the low-temperature drying device enters the interior of the box body 1 through the air inlet 13, and moves downward along the wind guide path composed of the condensation plate 2 and the wind shield 3. There is a refrigerant in the condensation plate 2 that circulates and absorbs heat, resulting in a low surface temperature of the condensation plate 2. After the air containing water vapor and fine dust hits the surface of the condensation plate 2, the water vapor is condensed into water, and the condensed water is mixed with part of the fine dust and flows downward. The air flows into the groove 16 along the guide groove 21, and then enters the liquid collecting pool 11 along the groove 16. After passing through a series of condensation paths, the air becomes dry and cold air containing a large amount of dust and a small amount of moisture. The air enters the cyclone dust collector and the pulse dust collector connected thereto through the air outlet 14. The mixture of condensed water and dust entering the liquid collecting pool 11 is discharged through the sewage outlet 12 at the bottom and enters the liquid-solid separation device at the back for further separation. The solid part contains a large amount of high-value spore powder, which can be further dried by low-temperature drying before use to avoid material waste.
