Tower-type filtering device for biomass-based fermented mash

Abstract

The invention discloses a tower-type filtering device for biomass-based fermented mash. The tower-type filtering device comprises two same tower-type filters, wherein discharge openings of the two tower-type filters are respectively connected with an inlet of a matured mash collecting tank through a pipeline provided with a valve, an outlet of the matured mash collecting tank is connected with aninlet of a matured mash concentration tower through a pipeline provided with a centrifugal pump, feeding openings of the two tower-type filters are respectively connected with a discharge pipe from the matured mash storage tank through a liquid inlet pipeline provided with the valve; three levels of filtering units are orderly arranged in each tower-type filter from top to bottom at intervals, a manhole is formed on a tower body side wall of each tower-type filter, an emptying opening is formed on the top wall, and pressure gauges are respectively installed at an upper seal head and a lower seal head of each tower-type filter. By adopting the device, since being connected in parallel, the two filters can be used in a switching manner and can be maintained simply and conveniently; the filter can be prevented from being frequently dismounted so as to guarantee the continuous, stable and safe operation of the system and the high filtering efficiency.

Description

Technical field [0001] The present invention relates to a filtration device for the fermentation mash of biomass (grain crops such as corn or corn stalks, cassava and non-grain crops), and particularly relates to a solid content containing protein and other derivatives produced during the fermentation process, sometimes in a paste or flocculent nature The device used for filtering. Background technique [0002] Biomass-based fermentation often produces proteins or other biological derivatives, which are present in the mature mash in the form of paste or floc. Conventional filters for filtering mash such as figure 1 As shown, it includes an inlet and outlet, a cylinder body 4, upper and lower sieve plates 1 and 3, and a wire filter 2 with an aperture of 120-200 mesh. During filtration, the mature mash enters the filter from the inlet at the top of the filter, and then flows through the upper sieve plate 1, and then through the filter mesh 2, and then flows through the lower sieve...

AI Technical Summary

Problems solved by technology

because figure 1 The designed filter screen 2 is usually made of 120-200 mesh wire mesh, and the paste or flocculent protein or other biological derivatives in the fermented mash are often difficult to pass through the wire filter screen 2, and it is very easy to adhere to the metal mesh. On the silk filter screen 2 and the upper sieve plate 1, it affects the normal operation of the mature mash concentration tower in the subsequent process

Greatly reduce the factory operating rate and economic benefits
