Abstract
The utility model discloses a filtering device, which relates to a filtering device in the process of producing 2, 6 acids. The filtering device comprises an upper cover with a liquid inlet, a lower cover connected with the upper cover and provided with a liquid outlet and a porous plate located between the upper cover and the lower cover, wherein the porous plate is arranged above a support frame; and a filtering medium is placed above the porous plate. In the filtering medium, filtering cloth is arranged at the bottom, and multiple layers of superposed neutral qualitative filtering paper is arranged above. Pressure filtration is carried out on recrystallized and decolored liquid to remove most activated carbon; then the liquid is led to the filtering device and particle activated carbon can be totally removed through the filtering action of multiple layers of neutral qualitative filtering paper and the filtering cloth. The quality of the product is greatly improved, and thereby, the requirements of customers on impurities being less than 10ppm can be satisfied.
Description
Technical field
The utility model relates to filter, specially refers to the filter in 2, the 6 sour processes of production.
Background technology
At present, 2,6 acid are that 2-hydroxyl 6-naphthoic acid (HNA) is a kind of emerging fine-chemical intermediate, not only be widely used in medical industry and organic pigment industry, and aspect II type heat modification liquid crystal polymer (Thermotropic Liquid Crystallicin Polymer is called for short TLCP) synthetic, more fine application prospect arranged.According to statistics, the growth of global annual requirement keeps the double-digit growth rate, more keeps the rapid growth rate in the area, Asia, and growth rate is up to 30%, and this rapid growth rate will be kept in nearly 10 years.Yet, be that raw material is produced in 2, the 6 sour processes with Koble-Schmitt reaction with the beta naphthal, will be through the mother liquor after salify, drying, carboxylation, neutralization, the layering with the processing of decolouring of activated carbon and zinc powder; After activated carbon and zinc powder are fallen in press filtration, mother liquor is carried out acid out, the crude product that obtains 2,6 acid after the separation processing that need be recrystallized and decolour.With crude product 2,6 acid, solvent and water drop into dissolving pan, and with activated carbon and fluid separation applications, liquid further concentrates, is separated into refining 2,6 acid with filter in stirring intensification back.In order to increase adsorption area, often use the particulate activated carbon, also be difficult to avoid seepage in the operation of press filtration simultaneously, more or less can carry tiny activated carbon granule secretly in the product like this, very big to the product quality influence.
The utility model content
The technical problems to be solved in the utility model is to overcome deficiency of the prior art, proposes a kind of new filter, can remove the tiny activated carbon granule in the process mixture of this device effectively, thereby has improved the quality of product.
The utility model is to realize by following technical measures.A kind of filter comprises the loam cake that has inlet, the lower cover that has liquid outlet that is connected with loam cake, and the porous plate between upper and lower cover is placed on the filter medium of porous plate top.
Described filter medium is a filter cloth.
Filter medium above described filter cloth is the neutral qualitative filter paper of multilayer.
Below described lower cover inside and porous plate, be bearing support.
After the utility model adopts abovementioned technology, will carry out operations such as press filtration, remove most of active carbon through the liquid of recrystallization and decolouring operation.Introduce the inlet of this device again; filtration through neutral qualitative filter paper of multilayer and filter cloth; particulate activated carbon all can be removed; every filtration is a collection of just can see that many particulate activated carbon stains are arranged on the paper; leaving the liquid of the liquid outlet of this device will further lower the temperature and separate, and obtains refining 2,6 acid; can satisfy the client to the requirement of impurity less than 10ppm, the quality of product is greatly improved.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Among the figure: 1 is loam cake, and 1-1 is an inlet, and 2 is lower cover, and 2-2 is a liquid outlet, and 3 is multiple filtration paper, and 4 is filter cloth, and 5 is porous plate, and 6 is bearing support.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment: as shown in the figure, a kind of filter comprises the loam cake 1 that has inlet 1-1, the lower cover that has liquid outlet 2-2 2 that is connected with loam cake 1; Porous plate 5 between loam cake 1 and lower cover 2, porous plate 5 is placed on the top of bearing support 6, and is clamped by the connector of loam cake 1 and lower cover 2; What be placed on porous plate 5 tops is filter medium.In filter medium, the below is filter cloth 4, and it not only can filtration, can also work to set off the multiple filtration paper 3 of top; 3 on multiple filtration paper is closed by the neutral qualitative filter quires of several layers and forms, and bears main filtration.
To carry out operations such as press filtration through the liquid of recrystallization and decolouring operation, remove most of active carbon.Introduce the inlet 1-1 of this device again; filtration through neutral qualitative filter paper 3 of multilayer and filter cloth 4; particulate activated carbon all can be removed; every filtration is a collection of just can see that many particulate activated carbon stains are arranged on the paper; leaving the liquid of the liquid outlet 2-2 of this device will further lower the temperature and separate, and obtains refining 2,6 acid; can satisfy the client to the requirement of impurity less than 10ppm, the quality of product is greatly improved.
Above-described only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
