Embodiment 1

[0030] A filter press device for multi-stage filtration serial feeding, including several filter plates 8, inter-plate passages 7 are arranged between the filter plates 8, and filter cloth 5 is fixedly arranged on one side of the filter plates 8, The side of the filter cloth 5 close to the filter plate 8 is fixed with a filtrate collecting device, the filtrate collecting device is arranged on the side of the filter plate 8 for material filtration, and the filtrate collecting device is connected with a filtrate channel 4 , the filtrate channel 4 communicates with the inter-plate channel 7, the filtrate channel 4 is arranged at the end of the filter plate 8, and the filtrate channels 4 on each filter plate 8 are arranged alternately up and down.

[0031] The filtrate collecting device comprises a plate frame 1, on which several columns 6 are fixedly arranged, one end of the column 6 is in contact with the filter cloth 5, and the other end is connected with a liquid collection cha...

Embodiment approach

[0041] Taking the waste acid liquid absorbed by the spray tower as an example, filter cloths in the range of 1-100 microns are selected, and there are 10 filter cloths 5 in 10 levels, which are fixed on 10 filter plates 8 that are staggered and assembled, and the material delivery pressure of 1MPa is adopted. Feed to the filter press. During the waste liquid filtration process, the waste liquid is fed from the upper corner of the filter plate 8 and passes through the primary filter cloth 5 to achieve the filtration of coarse particles. The filtrate passes through the liquid collection chamber 9 and flows to the liquid collection tank 3 , through the inter-plate channel 7, enter the second-stage liquid collection chamber 9, and pass through 10 stages of filtration in turn, finally realizing the regeneration of waste liquid.

[0042] It should be noted that the filter press and its supporting structure are existing prior art, and will not be described in the present invention.

Abstract

The invention discloses a filter pressing device for multi-stage filtration tandem feeding, belongs to the technical field of resource recovery and aims to solve the problems that multi-gradient filtering cannot be realized due to the fact that filter cloth used by the same equipment has the same specification in the prior art. The filter pressing device comprises a plurality of filter plates, inter-plate channels are arranged among the filter plates, one side of each filter plate is fixedly provided with filter cloth, a filtrate collecting device is fixedly arranged on the side, close to the filter plates, of the filter cloth, the filtrate collecting device is arranged on the sides, used for filtering materials, of the filter plates, the filtrate collecting device is connected with filtrate channels, the filtrate channels are communicated with the inter-plate channels and arranged at the ends of the filter plates, and the filtrate channels on the filter plates are staggered in a vertical direction; and therefore, various particles can be effectively filtered for a long time on the same equipment.

Description

technical field [0001] The invention belongs to the technical field of resource recovery, and in particular relates to a pressure filter device for multi-stage filtration and serial feeding. Background technique [0002] In the process of chemical production, a large amount of exhaust gas will be generated. With the increasingly severe environmental problems, exhaust gas treatment has become a problem that many enterprises must face. The current common tail gas treatment process is to absorb the acidic or alkaline components in the tail gas through the spray tower, and at the same time carry the solid particles in the tail gas into the waste liquid generated by the spray. The waste liquid is usually strongly acidic or alkaline, and cannot be directly discharged into external waters, which will cause serious environmental pollution. The current conventional waste liquid treatment method is to use other acidic or alkaline waste residues for neutralization treatment, then use ...
