Description
Technical field
The present invention relates to the technical field of grain dry machinery, specifically a kind of crop dryer environmental protection control of dust room.
Background technology
Cereal is need to carry out drying process, so that the following process of cereal or long term storage to cereal from gathering in the process stored.And the drying machine by combustion fuel mode that the crop dryer of heat-pump-type is more traditional, its advantage that pollution is little, energy consumption is low, cost is low is particularly evident, therefore, prior art has increasing heat-pump-type crop dryer already for substituting the drying machine of traditional combustion fuel mode.Such as application publication number is the patent application of the heat pump drying equipment of CN103438682A.
But the crop dryer of the prior art, the dust granules such as a large amount of husks are carried in the waste gas of discharging after the hot gas of its heat pump for supply carries out grain-drying by baking zone, direct discharge will cause atmosphere pollution, not only affect the health of human body of operating personnel, and the production environmental requirement of national regulation cannot be reached.
Summary of the invention
Technical problem to be solved by this invention is: providing a kind of can carry out high efficiency filter by the waste gas of discharging in crop dryer, thus the crop dryer environmental protection control of dust room of the dust granules removed in waste gas and impurity.
The technical solution used in the present invention is: provide a kind of crop dryer environmental protection control of dust room, it comprises casing, the screen pack group inner chamber of casing being separated into upper chamber and lower chambers is provided with in casing, lower chambers is provided with import, upper chamber is provided with the outlet supplying the waste gas of bottom chamber to discharge after filter screen group, it is characterized in that: described screen pack group comprises initial filter screen pack and is located at the top layer filter mechanism above initial filter screen pack.
After adopting above structure, crop dryer environmental protection control of dust room of the present invention compared with prior art has the following advantages: can be filtered the waste gas layering entering bottom chamber from import by initial filter screen pack and top layer filter mechanism, the air entered in upper chamber is purified fully.
As preferably, the inwall that described top layer filter mechanism comprises outer surface and casing fixes and the framework sealed, to be located in framework and the plane surrounded by frame inner surface is divided into the footpath bar of some air inlet unit, be equipped with the cloth-bag type screen pack of a covering air inlet unit in each air inlet unit, the edge of the openend of cloth-bag type screen pack and the edge of air inlet unit are fixed.By last one deck screen pack is set to the filter area that cloth-bag type structure can improve screen pack, improve air output, what therefore the mesh of cloth-bag type screen pack can be arranged under the prerequisite reaching equal air output is less, and filter effect is better.
