Description
Technical Field
The utility model relates to a chemical raw material production facility technical field, in particular to buffering demister of cyanopyridine production.
Background
Cyanopyridine is a white crystal, is commonly used in the pharmaceutical and food industries, and in the production process of cyanopyridine, because the melting point of cyanopyridine is relatively low, the cyanopyridine is often in a liquid state before a crystallization process, and a liquid foam entrainment phenomenon often occurs in equipment with vapor-liquid two-phase flow, such as a crystallizer and a distillation tower.
In order to prevent and reduce entrainment of liquid foam, a defoaming design needs to be considered on the evaporator and the crystallizer. The prior demister is of various types, and most of the prior defoamers are wire mesh defoamers. Due to poor anti-fouling and plugging capabilities, easy scaling and blockage and poor defoaming effect. Therefore, a new buffer demister for cyanopyridine production needs to be designed.
Disclosure of Invention
The utility model aims to solve the technical problem overcome prior art's defect, provide a simple structure, have stronger prevent blockking up the ability and prevent that the liquid foam from smuggleing secretly the ability, be difficult to the scale deposit, even the scale deposit also changes the washing easily, long service life's a buffering demister for cyanopyridine production.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a buffer demister for cyanopyridine production comprises a sealed container, wherein the top of the container is provided with a detachable cover plate, the bottom of the container is provided with a plurality of parallel grooves, cyanopyridine flows in the grooves, and the cyanopyridine can flow into the next groove after being filled in the groove; a plurality of parallel defoaming plates are arranged below the cover plate, each defoaming plate corresponds to one groove, and the defoaming plates are inserted into the grooves to adsorb and defoam cyanopyridine in the grooves; the left side of the container is provided with an inlet for injecting cyanopyridine, and the right side of the container is provided with an outlet for flowing out cyanopyridine.
In the above scheme, defoaming board and apron between be connected for dismantling, can change the washing to defoaming board.
In the above scheme, the inlet is further provided with a buffer device, the buffer device is an arc-shaped slope and is arranged below the inlet, and the slope is opposite to the inflow direction of the cyanopyridine at the inlet, so that the cyanopyridine flows into the groove after being buffered along the slope.
In the above scheme, exit position department, still be provided with the filter, the filter is the silk screen filter, carries out the secondary filter defoaming to the clean liquid foam of not adsorbing.
In the above scheme, the foam removing plate is a carbon fiber plate with a capillary structure, and liquid foam is adsorbed by the adsorption effect of the capillary structure.
The principle of the utility model lies in:
change traditional pure silk screen filter and remove the foam mode, adopt the defoaming board that can dismantle the change to adsorb and remove the foam, can save equipment investment greatly, be favorable to the later maintenance management, have stronger defoaming function moreover.
The utility model discloses owing to adopted above-mentioned technical scheme, following beneficial effect has:
the device of the utility model is simple in structure, have stronger anti-clogging ability and prevent that the liquid foam from smuggleing secretly the ability, be difficult to the scale deposit, even the scale deposit also changes the washing easily, prolonged the life of demister greatly.

Detailed Description
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.
As shown in figure 1, a buffer demister for cyanopyridine production comprises a sealed container, wherein the top of the container is provided with a detachable cover plate 1, the bottom of the container is provided with four parallel grooves 2, cyanopyridine flows in the grooves 2, and the cyanopyridine can flow into the next groove after being filled in the groove; four parallel defoaming plates 3 are arranged below the cover plate 1, the defoaming plates 3 are carbon fiber plates with capillary pore structures, liquid foams are adsorbed through the adsorption effect of capillary pores, the defoaming plates 3 are detachably connected with the cover plate 1, and the defoaming plates 3 can be replaced and cleaned; each defoaming plate 3 corresponds to the position of one groove 2, and the defoaming plates 3 are inserted into the grooves 2 to adsorb and defoam cyanopyridine in the grooves 2; the left side of the container is provided with an inlet 4 for injecting cyanopyridine, and the right side of the container is provided with an outlet 5 for flowing out cyanopyridine. The inlet 4 is also provided with a buffer device 6, the buffer device 6 is an arc slope and is arranged below the inlet 4, and the slope is over against the inflow direction of the cyanopyridine, so that the cyanopyridine flows into the groove 4 after being buffered along the slope. 5 positions department of export, still be provided with filter 7, the filter is 7 silk screen filters, carries out the secondary filter defoaming to the clean liquid foam of not adsorbing.
During the use with cyanopyridine from entering 4 injections of mouth, cyanopyridine will slowly flow into last slot from first slot, and the absorption defoaming of the board 3 is removed through quartic in the middle of, can reach good defoaming effect, passes through filter 7 at last, from export 5 discharges.
