A capsule type solid-liquid separation device and method

Abstract

A capsule-type solid-liquid separation device comprises a rough filtration device, a slurry storage tank, a transfer pump, a filter press and associated pipelines and valves, which are intensively arranged on a box using as a storage tank for slurry and filter cake. A preliminary filtrate passage of the rough filtration device is connected with a sewage pipe network, and a slurry discharge passage is connected with the slurry storage tank; a slurry feed pipeline of the transfer pump is connected with the slurry storage tank, and a slurry discharge pipeline is connected with the filter press; the filter press is a capsule-type one, a filter cylinder is provided inside with the pressing capsules, and a blanking passage is provided inside with filling capsules; the pressing capsules expand under the effect of the introduced high pressure fluid, and extrude the filter material in the filter cylinder for operation; the filling capsules expand under the effect of the introduced pressure fluid and fill the blanking passage, to cut off a lower opening of the filter cylinder with the blanking passage; and the blanking passage is communicated with the filter cake storage tank. The device has the advantages of compact structure, little land occupation, no noise and easiness for movement, and is especially suitable for solid-liquid separation of kitchen garbage crushing fluid in high buildings and in the field.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation in environmental protection engineering technology. Background technique [0002] The field of solid-liquid separation technology is very broad, and has extended to many process disciplines, and plays a very important role in many industries. In the field of environmental protection, solid-liquid (gas) separation involves issues such as water environmental protection, atmospheric environmental protection and comprehensive utilization of resources. There are many types of solid-liquid separation equipment, such as box filter press with frame plate, diaphragm filter press, vacuum drum filter, belt press filter, tube hydraulic press, pressurized leaf filter, etc. Machine and vertical filter press, etc. However, for the pressure filtration operation of the kitchen waste pulverization liquid that emits peculiar smell in high-rise buildings, the above solid-liquid separation equipment ...

AI Technical Summary

Problems solved by technology

However, for the pressure filtration operation of the kitchen waste pulverization liquid that emits peculiar smell in high-rise buildings, the above solid-liquid separation equipment has its own incompatibility. The problem of odor nuisance will occur if the filter equipment is used; the solid-liquid separation equipment such as vacuum drum and vertical hydraulic press has the problems of large area, large processing capacity and many auxiliary facilities; the use of the filter element as the original filter element Tubular filter press and leaf filter are inconvenient to be transported because of their liquid slag discharge; and centrifugal separation and screw press solid-liquid separation equipment, which will generate large noise during operation and are not suitable for living Environment use

[0003] Therefore, it is difficult to select equipment for solid-liquid separation of kitchen waste pulverization liquid in high-rise buildings with limited area and space and strict requirements on odor and noise.
