Low-temperature vacuum dehydration and drying equipment as well as process thereof

Abstract

The invention discloses a set of low-temperature vacuum dehydration and drying equipment as well as a process thereof, wherein the equipment comprises a filtering system, a filter pressing system, a heating and circulating system, a vacuumizing system as well as an air compressor system, wherein the filtering system comprises at least one diaphragm filtering plate and at least one heating filtering plate; material chambers are arranged between the heating filtering plates and the diaphragm filtering plates; the diaphragm filtering plates are provided with first material inlets and first outlets; the heating filtering plates are provided with second material inlets and second outlets; the first material inlets and the second material inlets are respectively connected with the material chambers; the first outlets and the second outlets are connected; the diaphragm filtering plates are also provided with first liquid inlets and first liquid outlets; the heating filtering plates are also provided with second liquid inlets and second liquid outlets; one end of the filter pressing system is connected with the first liquid inlets of the diaphragm filtering plates, and the other end of the filter pressing system is connected with the first liquid outlets; one end of the heating and circulating system is connected with the second liquid inlets of the heating filtering plates, and the other end of the heating and circulating system is connected with the second liquid outlets. By the set of low-temperature vacuum dehydration and drying equipment, the working procedures of dehydration, washing, filter pressing, drying and the like of materials can be completed.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation, and in particular relates to a complete set of low-temperature vacuum dehydration and drying equipment and a process thereof. Background technique [0002] It is a big problem to carry out solid-liquid separation for difficult-to-handle fine-grained materials and materials that require a high solid content of the filter plate. In addition, the traditional process is complicated. For example, the disposal of sludge requires multiple independent processes, and the traditional drying equipment and dehydration equipment are separated, which occupies a large area. At the same time, it takes time and labor to switch between dehydration and drying, which increases Due to the pressure of environmental protection and safety, the reduction of materials cannot be achieved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a comple...
