Abstract

The invention discloses a waste diatomite drying system. The waste diatomite drying system comprises a mixed sludge tank, wherein a multi-disc screw press sludge dewatering machine is connected with asludge outlet of the mixed sludge tank, a buffer bin is connected with a residue outlet of the multi-disc screw press sludge dewatering machine, a waste water tank is connected with a water outlet ofthe multi-disc screw press sludge dewatering machine, the buffer bin is connected with a low-temperature dehumidification drying machine by a screw conveyor, the low-temperature dehumidification drying machine comprises a strip cutting machine, a heat preservation box and a dehumidification heat pump, a discharging port of the screw conveyor is connected with a feeding port of the strip cutting machine, a discharging port of the strip cutting machine is connected with the heat preservation box body, an upper-layer mesh belt conveyor and a lower-layer mesh belt conveyor are arranged in the heat preservation box body, the heat preservation box is provided with a discharge port, the top of the heat preservation box is provided with exhaust ports, the bottom of the heat preservation box is provided with air inlets, and the exhaust ports and the air inlets are connected with the dehumidification heat pump. The waste diatomite drying system has the following advantages and effects that dry-wet separation can be efficiently achieved, no tail gas is generated during the handling process, and the waste diatomite drying system is environmental-friendly and is low in fault rate and high in stability.

Description

technical field [0001] The invention relates to the technical field of beer production, in particular to a waste diatomaceous earth drying system. Background technique [0002] The beer production process is divided into six sections, namely crushing, saccharification, wort, cooling, fermentation, filtration and filling. Waste water is mainly produced in each section, including the mixture of waste diatomaceous earth and waste water. Brewery wastewater has high concentration, large flow, and wide pollution area. Direct discharge will pollute surface water and groundwater. [0003] Because beer waste contains a large amount of wastewater, it is extremely difficult to directly treat it in an environmentally friendly manner. In addition, the existing country has strict environmental protection controls, and the treatment of beer waste has become the top priority of breweries today. Waste can only be treated step by step through stage-by-stage treatment to make it meet the emi...
