Abstract
The utility model relates to a gas vortex separator with a cooler. A vortex device of a shunting device is composed of an exhaust funnel and a vortex funnel body which are sheathed with each other; a tangential inlet pipe and an overflow drain pipe are arranged on the vortex funnel body. A cylindrical jacket is connected with the external wall of the vortex funnel to form a cooler. The utility model can separate liquescent components in gas, which is suitable for the purification and the recovery of end gas containing nitrogen oxide in the production of chemical industry. If the gas vortex separator is used in the production of preparing oxalic acid by a nitric acid oxidizing method, only the recovery rate of the concentrated nitric acid can be improved, but also the pollution from the end gas being discharged to the atmospheric environment can be reduced. The utility model has the advantages of simple structure, low cost, easy assemblage and maintenance, etc.
Description
The utility model is a kind of application free vortex flow device that disposes cooler.
Contain the separation of the mist of easy liquefaction component, generally the separator by the band condenser pipe carries out.Though this separator heat exchange area is bigger, cooling velocity is fast, exists the apparatus structure complexity, maintenance difficult, the high deficiency of energy consumption.
It is a kind of to containing the device that easy liquefaction component gases is separated that the purpose of this utility model is to provide, and that this device has is simple in structure, be convenient to remarkable advantages such as assembling maintenance and separative efficiency height.
The overall structure of gas cyclone separator is:
Cyclone is made of aiutage (3) and eddy flow cylindrical shell (2) suit, and the aiutage lower port is in eddy flow cylindrical shell low inside puts, and the top of eddy flow cylindrical shell is provided with air inlet pipe (7), and the cylindrical shell bottom is provided with discharging tube (6).Cylindric external jacket (1) connects the cooler that constitutes this separator with the whirl cylinder outer wall, offer on the external jacket cooling fluid into and out of the mouth of pipe (4), (8).
The design feature of this separator is that eddy flow cylindrical shell bottom is cone (5), and the discharging tube that connects with the vertex of a cone adopts the overflow-type structure, and described air inlet pipe (7) is the tangential admission pipe that Reducer (9) is housed.
When this device was used for the vent gas treatment of oxalic acid production, the eddy flow cylinder internal diameter was 330mm, and the aiutage internal diameter is 156mm, and the external jacket internal diameter is 330mm, and the height overall of separator is about 1600mm.Tail gas discharging pipe UNICOM in air inlet pipe wherein (9) and the oxalic acid production equipment, the aiutage upper port connects with air inlet pipe in oxidation one absorption equipment.
Accompanying drawing of the present utility model has:
Fig. 1 is the overall structure figure of gas cyclone separator.
Fig. 2 is the A-A cutaway view of Fig. 1.
Accompanying drawing has provided an embodiment of the present utility model, in conjunction with the accompanying drawings its operation principle is described as follows
The utility model can absorb the preposition equipment of operation as the oxidation one of nitrogen-containing oxide.According to the liquefaction point difference of contained gas composition in the tail gas, under the double action of separating cooling and rotational flow separation, some non-nitrogen oxide composition deliquescence is separated, nitrogen-containing oxide purer after separating can be reclaimed system nitric acid simultaneously.
Tail gas during oxalic acid is produced is tangentially injected through air inlet pipe (7) spin current cylindrical shell top, forms eddy flow in cylindrical shell.Air-flow is with after barrel contacts, carry out heat exchange with cooler, make that liquescent non-nitrogen oxide component (as methyl alcohol, ethanol, sulfuric acid etc.) is condensed into drop in the tail gas, under cyclonic action, dirty along barrel, discharged by overflow pipe through bottom cone, the liquid of discharge can directly be sent in the mother liquor for preparing oxalic acid and recycle.From the tail gas that the aiutage upper port gives off, contain comparatively pure nitrogen-containing oxide, be specially adapted to reclaim system nitric acid.
The about 100mm water column of the inlet, outlet pressure reduction of this device forms eddy flow to guarantee gas, and the cooling fluid in the cooler is saline solution or other cooling liquid (gas) bodies.
The technological progress that the utility model is obtained.
1, this separator can be widely used in the Chemical Manufacture purification and the recovery of nitrogen-containing oxide tail gas, is conducive to improve the rate of recovery of nitrogen oxide, reduces nitrogen-containing oxide to the pollution of atmospheric environment.
2, in oxalic acid is produced, use this separator and process tail gas, both can make red fuming nitric acid (RFNA) It is 97% that the rate of recovery reaches the 75.3%(concentration of nitric acid) content that can guarantee again nitrogen oxide in the emission in the 150-170ppm scope, reach the standard (200ppm is following) of environmental regulations.
3, separating effect of the present utility model is remarkable, the recovery utilization rate height of separator. Be a kind of simple in structure, cost is low, be easy to assemble maintenance, spiral-flow type separator that energy consumption is low.
Claims (3)
1, a kind of gas cyclone separator is made up of cyclone, cooler and corresponding draw bail, it is characterized in that cyclone is made of aiutage (3) and eddy flow cylindrical shell (2) suit, the aiutage lower port is in eddy flow cylindrical shell low inside and puts, the top of eddy flow cylindrical shell is provided with air inlet pipe (7), the cylindrical shell bottom is provided with discharging tube (6), cylindric external jacket (1) connects the cooler that constitutes this separator with the eddy flow cylinder body outer wall, offer on the external jacket cooling fluid into and out of the mouth of pipe (4), (8).
2, separator according to claim 1 is characterized in that eddy flow cylindrical shell bottom is cone (5), and the discharging tube that connects with the vertex of a cone adopts overflow-type structure (6), and described air inlet pipe (7) is the tangential admission pipe that Reducer (9) is housed.
3, separator according to claim 1 and 2 is characterized in that the eddy flow cylinder internal diameter is that 216mm, aiutage internal diameter are 156mm when this device is used for the vent gas treatment of oxalic acid production, and the external jacket internal diameter is 330mm, the about 1600mm of the height overall of separator; Tail gas discharging pipe UNICOM in air inlet pipe wherein (9) and the oxalic acid production equipment, the aiutage upper port connects with air inlet pipe in oxidation one absorption equipment.
