Abstract
The utility model discloses a high specific surface is used for production system of synthetic vinyl acetate carrier active carbon of acetylene method, including feeder, converter, water tank, ebullated bed, the feed inlet of feeder and converter link to each other, the ebullated bed links to each other with the discharge gate of converter, the converter outside have a combustion chamber, the inside of converter is provided with the heat transfer interior conduit, the afterbody of converter still is provided with the waste heat coil pipe, waste heat coil pipe and water tank link to each other. This system has avoided the heat loss on exhaust -heat boiler equipment surface, has improved the thermal efficiency, has improved simultaneously and has got rid of efficiency.
Description
Technical field
The utility model relates to gac field, particularly relates to the production system of a kind of high-ratio surface for Synthesizing Vinyl Acetate from Acetylene carrier active carbon.
Background technology
Substantially captured by Japanese imported product for Synthesizing Vinyl Acetate from Acetylene carrier active carbon market, compared with japanese product, there is acetic acid absorption low in homemade goods, the shortcomings such as ash content is high.Its reason is gac in reactivation process because the activation temperature that heat exchange area causes not causes product acetic acid absorption index low not, if cause again large content of starting materials spontaneous combustion excessively to cause ash too high by increasing fuel in activation furnace combustion raising activation temperature.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of high-ratio surface for the production system of Synthesizing Vinyl Acetate from Acetylene carrier active carbon.This system obviates the thermal losses of waste heat boiler equipment surface, improve thermo-efficiency, improve removal efficiency simultaneously.
The utility model is achieved by the following technical solution: a kind of high-ratio surface is used for the production system of Synthesizing Vinyl Acetate from Acetylene carrier active carbon, comprise feeder, converter, water tank, ebullated bed, described feeder is connected with the opening for feed of converter, ebullated bed is connected with the discharge port of converter, outside described converter, there is combustion chamber, the inside of converter is provided with heat exchange inner tube road, and the afterbody of converter is also provided with waste heat coil pipe, and described waste heat coil pipe is connected with water tank.
Further, described heat exchange inner tube road is vertically arranged closely in converter inside.
Further, described converter afterbody is also connected with converter feed inlet end by vapour pipe, for providing the high-temperature steam in converter anaerobic activating process.
Further, the ebullated bed of what described ebullated bed adopted is top and bottom blowing.
The utility model compared to existing technology, has following beneficial effect:
1, the utility model can improve heating surface area and the thermo-efficiency of external-heat converter, reduces energy consumption and cost: in converter body, insert heat pipe, the heating surface area be doubled.
2, the utility model eliminates the waste heat boiler in traditional technology, adopts coil pipe direct heat exchange to produce the steam needed for producing, avoids the thermal losses of waste heat boiler equipment surface, improve thermo-efficiency.
3, the utility model adopts ebullated bed to remove ash content, improves removal efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: the converter of 1-1 external-heat, 1-2 combust room, 1-3 heat exchange inner tube road, 2-1 waste heat coil pipe, 2-2 vapour pipe, 2-3 water tank, 3-1 ebullated bed.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure.A kind of high-ratio surface is used for the production system of Synthesizing Vinyl Acetate from Acetylene carrier active carbon, comprise feeder, converter, water tank, ebullated bed, described feeder is connected with the opening for feed of converter, ebullated bed is connected with the discharge port of converter, outside described converter, there is combustion chamber, the inside of converter is provided with heat exchange inner tube road, and the afterbody of converter is also provided with waste heat coil pipe, and described waste heat coil pipe is connected with water tank.
Further, described heat exchange inner tube road is vertically arranged closely in converter inside.
Further, described converter afterbody is also connected with converter feed inlet end by vapour pipe, for providing the high-temperature steam in converter anaerobic activating process.
Further, the ebullated bed of what described ebullated bed adopted is top and bottom blowing.
Principle of work of the present utility model is as follows:
The utility model is the heat exchange inner tube road 1-3 at external-heat converter 1-1 indoor design solid matter, knot like this can ensure that the high-temperature flue gas combusting room 1-2 combustion of external-heat converter 1-1 periphery enters in the heat exchange inner tube road 1-3 of solid matter, the heat interchanging area that is heated of the material in external-heat converter 1-1 can be increased, improve thermo-efficiency, greatly reduce energy consumption and fuel cost, and ensure product yield and intensity while improving the quality of products.At the afterbody of external-heat converter 1-1, waste heat coil pipe 2-1 is installed, a large amount of high-temperature flue gas is walked in waste heat coil pipe 2-1 inside, the dripping device be connected with water tank 2-3 is had on the top of waste heat coil pipe 2-1, both steam was convertible into after water touches high-temperature residual heat coil pipe 2-1, this steam is connected with external-heat converter 1-1 by vapour pipe 2-2, for providing the high-temperature steam in converter anaerobic activating process.Top and bottom blowing ebullated bed in the utility model, for the stone in 3-1 removal product and other impurity, reduces the ash content of product, improves intensity.
