Abstract
The utility model relates to a device for adjusting the temperature of the top of a fractionating tower. The device is characterized in that a coil pipe in the top of the fractionating tower is respectively connected with a cooling water pipe and an air pipe; the air pipe is connected with an air compressor; the cooling water pipe is connected with a water tank through a water pump and is provided with a cooling water adjusting valve; and the air pipe is provided with an air adjusting valve. The device is simple in structure and convenient to use; owing to addition of air, a phenomenon that the temperature of the top of the tower is reduced over fast is avoided; and the temperature of the top of the fractionating tower is adjusted by properly adjusting the ratio of cooling water to air, then cutting points of the fractionating tower is controlled, and the yield of different fractions can be controlled.
Description
Technical field
The utility model relates to a kind of device of regulating the fractionator overhead temperature.
Background technology
With regard to the production of catalytic cracking unit, under the prerequisite that guarantees safety, product quality and environmental protection, suitably regulate the tower top temperature of fractionating column, and then the cut point of control fractionating column, thereby the yield of control different fractions, in the prior art, control the tower top temperature of fractionating column by the flow velocity of adjusting cooling water, but because the thermal capacitance of water is larger, even if when the flow velocity of water is very little, the tower top temperature of fractionating column reduces still very fast, can not satisfy production requirement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of device of regulating the fractionator overhead temperature is provided.
The technical solution adopted in the utility model is:
A kind of device of regulating the fractionator overhead temperature, it is characterized in that: the coil pipe in the fractionator overhead is connected with respectively cooling water pipeline and air duct, be connected with air compressor on the described air duct, described cooling water pipeline links to each other with water tank by water pump, be provided with cooling sea water regulating valve at cooling water pipeline, be provided with air control valve at air duct.
The beneficial effect that the utility model has:
The utility model is simple in structure, easy to use, because the thermal capacitance of air is very little, the adding of air, it is too fast to avoid tower top temperature to reduce, and cools off the appropriate proportioning of water and air by adjustment, thereby adjusts the tower top temperature of fractionating column, and then the cut point of control fractionating column, thereby the yield of control different fractions.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 is fractionating column among the figure; 2 is coil pipe; 3 is cooling water pipeline;
4 is air duct; 5 is water pump; 6 is water tank;
7 is air compressor, and 8 is cooling sea water regulating valve; 9 is air control valve.
The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
Embodiment 1
As shown in Figure 1, a kind of device of regulating the fractionator overhead temperature, it is characterized in that: the coil pipe 2 in fractionating column 1 cat head is connected with respectively cooling water pipeline 3 and air duct 4, be connected with air compressor 7 on the described air duct 4, described cooling water pipeline 3 links to each other with water tank 6 by water pump 5, be provided with cooling sea water regulating valve 8 at cooling water pipeline 3, be provided with air control valve 9 at air duct 4.
During use, regulate the flow that enters coil pipe 2 interior cooling waters by cooling sea water regulating valve 8, regulate the flow that enters coil pipe 2 interior air by air control valve 9, the thermal capacitance of water is larger, the thermal capacitance of air is very little, the suitable proportioning that enters the cooling water and air in the coil pipe 2 by adjustment, thus the tower top temperature of fractionating column adjusted.
Foregoing description is illustrative rather than determinate, therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
