Abstract
The utility model relates to a steam hydrophobic means for rectifying column reboiler. The structure mainly comprises: 1 reboiler (heat exchanger), 2 steam water pipeline, 3 water adding valve, 4 steam condensate water tank, 5 level meter, 6 blowoff valve, 7 automatic drain valve, 8 drain pump, 9 pipeline check valve. The utility model discloses use the mechanical type drain valve who replaces present universal use for the first time on p-chlorobenzaldehyde rectifying column, the utility model relates to a rationally, be water with the excessive steam condensation of the hydrophobic in-process of steam drain valve, can effectually get rid of the outer hidden danger that hurts the people and cause the pipe-line equipment of arranging of steam drain steam. Effectively reduces energy consumption and protects environment.
Description
Technical Field
The utility model belongs to the technical field of the chemical industry, concretely relates to steam trap of rectifying column reboiler
Background
At present, it is more to use steam heating rectifying column at the chemical production scene, discharge along with steam at hydrophobic in-process, steam trap fault rate is higher in addition, after steam trap trouble, drain line steam directly discharges to the environment on every side always outward, when causing steam waste, still can cause personnel to scald, also make equipment pipe on every side wet or ground freeze very easily, make the environment on every side moist moreover, cause certain corruption to equipment pipe, energy resource consumption has been increased.
SUMMERY OF THE UTILITY MODEL
The utility model provides a steam trap, the utility model relates to a rationally, be water with the excessive steam condensation of the hydrophobic in-process of steam trap, can effectually get rid of the outer hidden danger that hurts the people and cause pipeline equipment of arranging of the hydrophobic vapor of steam, simultaneously can the direct waste that causes of effectual reduction steam, reduce the energy consumption.
The utility model discloses the device does: reboiler comdenstion water passes through the pipeline and gets into steam condensate water pitcher, and the liquid level passes through the level gauge and shows in the steam water pitcher, through automatic control device, sets for according to the liquid level height, and automatic drain valve and drain pump are opened to the chain, keep the water level in the jar, reduce the waste of steam.
The utility model discloses the technical problem that will solve can also further realize through following technical scheme. The water tank for steam condensation can be added with 10-90% of water in advance, or not added, and is increased by steam condensation.
The utility model discloses the technical problem that will solve can also further realize through following technical scheme. The liquid level of the steam condensing tank can be controlled by the drainage of a drainage pump and also can be controlled by gravity flow.
The utility model discloses the technical problem that will solve can also further realize through following technical scheme. The liquid level meter of the steam condensate tank is interlocked with the automatic drain valve and can also be interlocked with the drain pump.
The utility model discloses the technical problem that will solve can also further realize through following technical scheme. And a pipeline check valve is additionally arranged on the drainage pipeline to prevent the backflow of the condensed water.
The utility model discloses the technical problem that will solve can also further realize through following technical scheme. The steam condensate tank discharges sewage regularly through a drain valve, so that foreign matter blockage is prevented.
Advantageous effects
The utility model discloses select for use steam condensate water device to replace mechanical type steam trap, can effectually get rid of the outer hidden danger that hurts the people and cause pipeline equipment of arranging of steam hydrophobic vapor, reduced the direct vent waste of steam, reduce the energy consumption, environmental protection, reduction in production cost.
Drawings
FIG. 1 is a schematic view of the apparatus of the present invention. In the figure, 1 is a reboiler, 2 is a steam condensate pipeline, 3 is a water adding valve, 4 is a steam condensate water tank, 5 is a liquid level meter, 6 is a drain valve, 7 is an automatic drain valve, 8 is a drain pump, and 9 is a pipeline check valve.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to FIG. 1
The utility model provides a steam hydrophobic means for rectifying column reboiler, reboiler 1 is through condensate water pipeline 2 entering steam condensate water pitcher 4 behind steam heating, steam condensate water pitcher adopts the carbon steel material, 1 water filling valve 3 is equipped with on upper portion, carry out earlier stage water injection through the valve, in operation, steam condensate water gets into steam condensate water pitcher 4, steam condensate water tank water level passes through level gauge 5 and shows, according to setting for after the liquid level increase, automatic drain valve 7 and drain pump 8, automatic operation, the pipeline increases pipeline check valve 9 behind the drain pump, prevent that water from flowing back to in the steam condensate water jar, 1 blowoff valve 6 of installation under the jar, periodic blowdown, whole hydrophobic means operation is stable. Thereby reducing the waste of steam, reducing energy consumption, protecting environment and reducing production cost.
The device has the following use process: firstly, 10% of water is added through a water adding valve to enter a steam condensation water tank, a steam valve of a reboiler of the rectifying tower is opened, condensed water enters the steam condensation water tank, the liquid level of the steam condensation water tank rises, after the liquid level reaches a set value, an automatic drain valve and a drain pump are linked and opened, the liquid level of the steam condensation water tank is reduced to the set value, and the device continuously and automatically operates.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
