Description
Technical field
The utility model relates to carbon black production equipment technology, particularly relates to a kind of technology of producing the arch-shaped bottom vaporization box reaction unit of carbon black for mixed gas method.
Background technology
The production of mixed gas method carbon black is mainly, by fire grate, vaporization box bottom-heated is made to the vaporization of liquid starting material oil, in vaporization box, inject the combustion gas of carrying through preheating simultaneously, carry gas-flow through heating liquids stock oil surface, the rapid rear and year combustion gas mixing of vaporizing of stock oil of upper layer, and enter fiery room from vaporization box outlet along gas mixture house steward, in fiery room, incomplete combustion generates carbon black smoke, and carbon black smoke obtains carbon black again after the processes such as overcooling, collection, granulation.
As shown in Figure 2, the inner chamber bottom surface 21 of the existing vaporization box 29 of producing for carbon black gas mixing is plane, in process of production, carry combustion gas and inject casing from the inlet mouth 23 at casing top, stock oil injects casing from oil guide pipe 22, fire grate 26 makes the stock oil in casing vaporize rear and carry a combustion gas mixing to the bottom-heated of casing 29, and mixed oil and gas enters fiery room from air outlet 24 again.The defect of this vaporization box is: because cabinets cavity bottom surface 21 is plane, be easy to coking, cause vaporization box to heat up difficult, do not reach stock oil vaporization temperature (360 degree), concurrently injected stock oil is also difficult for circulation, Residual oil discharge is unclean, do not have metathesis, not only can affect the intensification of vaporization box, and the utilization ratio of carrying combustion gas is not high yet, causes energy dissipation, also can affect the work-ing life of vaporization box, macrocyclic production is run well unfavorable, finally affect the quality product of carbon black.
Utility model content
For the defect existing in above-mentioned prior art, it is high that technical problem to be solved in the utility model is to provide a kind of combustion gas utilization ratio of carrying, and the arch-shaped bottom vaporization box reaction unit for mixed gas method production carbon black of long service life.
In order to solve the problems of the technologies described above, a kind of arch-shaped bottom vaporization box reaction unit of producing carbon black for mixed gas method provided by the utility model, comprises casing, and for heating the fire grate of casing;
The top of described casing offers inlet mouth, air outlet, and the side box wall bottom of casing offers Residual oil discharge outlet, and an oil guide pipe is housed on casing;
The lower end mouth of pipe of described oil guide pipe stretches into the inner chamber of casing, and the upper end mouth of pipe of oil guide pipe extends casing outside from the top of casing;
Described fire grate be arranged on casing under;
It is characterized in that: the inner chamber bottom surface of described casing is the cambered surface that upwards arc arches upward.
Further, the downward just arc top to cabinets cavity bottom surface of the lower end mouth of pipe of described oil guide pipe.
Further, the vertical spacing between the edge of described cabinets cavity bottom surface and arc top is 10% of box body diameter.
The arch-shaped bottom vaporization box reaction unit for mixed gas method production carbon black that the utility model provides, stock oil injects after casing, can evenly spread to surrounding along the cabinets cavity bottom surface that upwards arc arches upward, can effectively avoid the coking of cabinets cavity bottom surface, can extend the work-ing life of casing, also help the intensification of casing, stock oil in case can fully be vaporized, and then the utilization ratio of combustion gas is carried in raising, can guarantee that production of carbon black long period runs well, more convenient while draining the oil, can take more Residual oil out of, circulating effect is also better.
Brief description of the drawings
Fig. 1 is the structural representation of the arch-shaped bottom vaporization box reaction unit for mixed gas method production carbon black of the utility model embodiment;
Fig. 2 is the structural representation of the existing vaporization box of producing for carbon black gas mixing.
Embodiment
Below in conjunction with brief description of the drawings, embodiment of the present utility model is described in further detail, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof, all should list protection domain of the present utility model in.
As shown in Figure 1, a kind of arch-shaped bottom vaporization box reaction unit of producing carbon black for mixed gas method that the utility model embodiment provides, comprises casing 9, and for heating the fire grate 6 of casing 9;
The top of described casing 9 offers inlet mouth 3, air outlet 4, and the side box wall bottom of casing 9 offers Residual oil discharge outlet 5, and an oil guide pipe 2 is housed on casing 9;
The lower end mouth of pipe of described oil guide pipe 2 stretches into the inner chamber of casing 9, and the upper end mouth of pipe of oil guide pipe extends casing 9 outsides from the top of casing 9;
Described fire grate 6 be arranged on casing 9 under;
It is characterized in that: the inner chamber bottom surface 1 of described casing is the cambered surface that upwards arc arches upward.
In the utility model embodiment, the downward just arc top to cabinets cavity bottom surface 1 of the lower end mouth of pipe of described oil guide pipe 2.
In the utility model embodiment, described Residual oil discharge outlet 5 has two, and these two Residual oil discharge outlets 5 are symmetrical laying on the tank wall of casing 9.
In the utility model embodiment, the diameter of described casing is 260 centimetres, and be made up of chromium manganese steel cabinets cavity bottom surface 1, and the vertical spacing between the edge of cabinets cavity bottom surface 1 and arc top is the 10%(26cm of box body diameter).
