Abstract
The utility model discloses high-concentration caustic soda liquid and join alkali device, comprise: join alkali still, delivery pump, elevated tank with caustic soda liquid and reactor, join alkali still to be connected with the import of delivery pump by the first conveyance conduit, conveying delivery side of pump is connected with the import of elevated tank with caustic soda liquid by the second conveyance conduit, the outlet of elevated tank with caustic soda liquid is connected with reactor by discharge pipe, discharge pipe is provided with the valve that can open or close discharge pipe, it is characterized in that: at the first conveyance conduit, on the outer wall of delivery pump and the second conveyance conduit, tight voluble wrapping has the anticorrosion temperature selflimiting electric tracing band that automatically can regulate temperature.The utility model has and can effectively prevent conveyance conduit and delivery pump because of high-concentration caustic soda liquid generation of clogging due to temperature too low precipitation NaOH crystallization, advantage that operating efficiency is high.
Description
Technical field
The utility model relates to high-concentration caustic soda liquid and joins alkali device.
Background technology
At (R)-(+)-2-(4-hydroxyphenoxy) in the production process of propionic acid (be called for short " DHPPA "), need to use high-concentration caustic soda liquid to join alkali device and high-concentration caustic soda liquid is delivered to participation reaction in reactor, the structure that the high-concentration caustic soda liquid used at present joins alkali device is: comprise and join alkali still, join alkali still to be connected with the import of elevated tank with caustic soda liquid by conveyance conduit and delivery pump, the outlet of elevated tank with caustic soda liquid is connected with the import of reactor.The shortcoming that above-mentioned high-concentration caustic soda liquid joins alkali device is: when environment temperature is too low (as in the winter time), high-concentration caustic soda liquid easily separates out NaOH crystallization, and then blocks conveyance conduit and delivery pump, not only have impact on carrying out smoothly of production, and inconvenient maintenance, inefficiency.
Utility model content
The purpose of this utility model is to provide a kind of high-concentration caustic soda liquid of conveyance conduit and delivery pump blocking that can prevent and joins alkali device.
For achieving the above object, the utility model have employed following technical scheme: described high-concentration caustic soda liquid joins alkali device, comprise: join alkali still, delivery pump, elevated tank with caustic soda liquid and reactor, join alkali still to be connected with the import of delivery pump by the first conveyance conduit, conveying delivery side of pump is connected with the import of elevated tank with caustic soda liquid by the second conveyance conduit, the outlet of elevated tank with caustic soda liquid is connected with reactor by discharge pipe, discharge pipe is provided with the valve that can open or close discharge pipe, it is characterized in that: at the first conveyance conduit, on the outer wall of delivery pump and the second conveyance conduit, tight voluble wrapping has the anticorrosion temperature selflimiting electric tracing band that automatically can regulate temperature.
Further, aforesaid high-concentration caustic soda liquid joins alkali device, and wherein: on the first conveyance conduit, be provided with the valve that can open or close the first conveyance conduit, on the outer wall of valve, also closely voluble wrapping has the anticorrosion temperature selflimiting electric tracing band that automatically can regulate temperature.
Further, aforesaid high-concentration caustic soda liquid joins alkali device, wherein: on the outer wall of discharge pipe and in order on the outer wall of the valve that opens or closes discharge pipe also respectively closely voluble wrapping have the anticorrosion temperature selflimiting electric tracing band that automatically can regulate temperature.
By the enforcement of technique scheme, the beneficial effects of the utility model are: can effectively prevent conveyance conduit and delivery pump because of high-concentration caustic soda liquid generation of clogging due to temperature too low precipitation NaOH crystallization, considerably increase the safe handling of production, also improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is the operation principle schematic diagram that high-concentration caustic soda liquid described in the utility model joins alkali device.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, described high-concentration caustic soda liquid joins alkali device, comprise: join alkali still 1, delivery pump 2, elevated tank with caustic soda liquid 3 and reactor 4, join alkali still 1 to be connected with the import of delivery pump 2 by the first conveyance conduit 5, first conveyance conduit 5 is provided with first valve 6 that can open or close the first conveyance conduit 5, the outlet of delivery pump 2 is connected with the import of elevated tank with caustic soda liquid 3 by the second conveyance conduit 7, the outlet of elevated tank with caustic soda liquid 3 is connected with reactor 4 by discharge pipe 8, discharge pipe 8 is provided with second valve 9 that can open or close discharging 8, on the outer wall of the first conveyance conduit 5, on the outer wall of the first valve 6, on the outer wall of delivery pump 2, the outer wall of the second conveyance conduit 7, on the outer wall of discharge pipe 8, and second valve 9 outer wall on respectively closely voluble wrapping have the anticorrosion temperature selflimiting electric tracing band 10 that automatically can regulate temperature,
Operation principle of the present utility model is as follows: first the temperature of limit certainly of anticorrosion temperature selflimiting electric tracing band 10 is set as 60 degree, then open the first valve 6 and start delivery pump 2, the high-concentration caustic soda liquid of now joining in alkali still 1 enters elevated tank with caustic soda liquid 3 along the first conveyance conduit 5, second conveyance conduit 7 under the effect of delivery pump 2, then open the second valve 9 again, make the high-concentration caustic soda liquid in elevated tank with caustic soda liquid 3 enter in reactor 4 by the second valve 6 with discharge pipe 8; The first conveyance conduit 5, first valve 6, second conveyance conduit 7, second valve 9 is passed through with the process of discharge pipe 8 at high-concentration caustic soda liquid, anticorrosion temperature selflimiting electric tracing band 10 makes to flow through the first conveyance conduit 5, first valve 6, second conveyance conduit 7, second valve 9 all the time and controls at 60 degree with the temperature of the high-concentration caustic soda liquid of discharge pipe 8, thus effectively prevent high-concentration caustic soda liquid generation of clogging due to the too low crystallization of temperature, and then ensure that carrying out smoothly of production, not only increase the safe handling of production, also improve operating efficiency.
