specific Embodiment approach 1

[0007] Specific implementation mode one: combine figure 1 Describe this embodiment, this embodiment comprises box body 1, residual ammonia water distribution groove 2, plug-in filter screen 3, several dividing plates 4 and several iron cages 5, and described box body 1 is cuboid, and described box body 1 One end in the length direction is provided with a remaining ammonia water distribution tank 2, and the remaining ammonia water distribution tank 2 is provided with a tar-containing residual ammonia water inlet 2-1, and the other end of the box body 1 in the length direction is provided with an ammonia water outlet after detarring 1-1, several partitions 4 are arranged sequentially along the length direction of the box body 1, several partitions 4 divide the box body 1 into several filter boxes 1-2, and the remaining ammonia water distribution tank 2 corresponds to the filter box 1-2 Several water holes 1-3 are provided on the side wall of the box body between, and an iron cag...

specific Embodiment approach 2

[0009] Specific implementation mode two: combination figure 1 The present embodiment will be described. The number of filter boxes 1 - 2 in the present embodiment is six. Starting from one end of the remaining ammonia water distribution tank 2, the six filter boxes 1-2 are successively the first filter box, the second filter box, the third filter box, the fourth filter box, the fifth filter box and The sixth filter box, the size of the coke particles in the first filter box and the second filter box is more than 40mm×40mm, and the size of the coke particles in the third filter box and the fourth filter box is 25mm×25mm~40mm ×40mm, the size of the coke particles in the fifth filter box and the sixth filter box is below 10mm×10mm, this design makes the purification effect of residual ammonia water the best. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0010] Specific implementation mode three: combination figure 2 Illustrate this embodiment, what this embodiment is different from specific embodiment one is that it also increases several tar deposition tanks 6, and each filter case 1-2 is provided with a tar deposition tank 6 below, and the bottom end face of tar deposition tank 6 is positioned at One side of the remaining ammonia water distribution tank 2 is arranged inclined downward, and the inclination of the bottom end surface of the tar deposition tank 6 is 1:10˜1:30. This design makes the residual oil or impurities with poor fluidity easy to be discharged from the filter box 1-2 under the action of gravity, thereby ensuring the continuous, stable and efficient operation of the filter box 1-2. Other components and connections are the same as those in the first embodiment.

[0011] Specific implementation mode four: combination figure 2 Describe this embodiment, the difference between this embodiment and specific em...

Abstract

The invention provides a device for filtering ammoniacal liquor and tar by coke, and relates to a device for purifying residual ammoniacal liquor and tar. The invention is for solving the problems that the purification of residual ammoniacal liquor is performed by using coke in a cylinder, the purifying effect is poor, time consumption and labor consumption are generated due to coke removal and the process for making the cylinder is complicated. A residual ammoniacal liquor distribution groove is provided with one end of a device body along the length direction, the other end is provided with an outlet for ammoniacal liquor after detarring, a plurality of separator plates are successively arranged along the length direction of the device body, a plurality of separator plates are divided the device body into a plurality of filtering cases, a plurality of limbers are provided between the residual ammoniacal liquor distribution groove and the filtering case which corresponds with the residual ammoniacal liquor distribution groove, one metal cage is provided in each filtering case, one notch is provided on every separator plate, and the notches on the separator plates with odd numbers are positioned at the inner wall of same side of the case body, the notches on the separator plates with even numbers are positioned at the inner wall of the other side of the case body which corresponds with the notches on the separator plates with odd numbers, the bottom of each filtering case is provided with an oil and sewage draining outlet. The invention is used for purifying the residual ammoniacal liquor and tar.

Description

technical field [0001] The invention relates to a residual ammonia tar purification filter. Background technique [0002] There are many suspended tar floating droplets in the remaining ammonia water, and directly entering the ceramic filter of the ammonia distillation system will increase the burden on the ceramic filter and affect the normal progress of subsequent production. Therefore, it is necessary to purify the tar in the remaining ammonia water. At present, The tar purification in the remaining ammonia water is to add coke in the cylinder, and the remaining ammonia water enters from the inlet of the cylinder and is purified by coke and then discharged from the outlet to complete the purification of ammonia water. This scheme has the following disadvantages: the purification effect is poor, and the coke needs to It is time-consuming and labor-intensive to manually remove coke bit by bit. At the same time, the production of the cylinder is more complicated. Contents ...
