Abstract
The utility model relates to a safe and efficient liquid naphthalene conveying system, the structure of which comprises a liquid naphthalene metering tank, a sulfonation reaction kettle and a double-layered conveying pipeline which connects the liquid naphthalene metering tank with the sulfonation reaction kettle. The lower end port of the double-layered pipeline is connected with a submersible pump. The liquid naphthalene conveying system is safe and high efficient while being used. The submersible pump is adopted to convey the liquid naphthalene, so that the safety threats which are possibly caused by adopting compressed air as power to convey the liquid naphthalene are eliminated and the loss of the liquid naphthalene which is caused by emptying the sulfonation reaction kettle and the environmental pollution which is caused by the loss of the liquid naphthalene are avoided. The double-layered pipeline is adopted and heat of the liquid naphthalene is kept by introducing high-temperature steam into the outer pipe of the double-layered pipeline, so that the liquid naphthalene is prevented from solidifying during conveying and the operating efficiency of equipment is improved.
Description
Technical field
The utility model relates to a kind of liquid conveying system, specifically a kind of liquid naphthalene transporting system.
Background technique
Liquid naphthalene transporting system generally comprises liquid naphthalene measuring tank, sulfonating reaction still and is connected in conveyance conduit between the two.The conveying of liquid naphthalene generally is employed in the liquid naphthalene measuring tank with the method for pressurized with compressed air, is pressed into the liquid naphthalene in the sulfonating reaction still.There are two open defects in this structure for conveying: one, adopt pressurized with compressed air; Increased the unsafe factor of operation on the one hand, on the other hand, must be before using earlier with the emptying of sulfonating reaction still; Thereby cause the loss of many naphthalene raw materials, also polluted environment simultaneously; Two, the solidifying point of naphthalene is 80.5 ℃, and carries the pipeline of naphthalene generally to adopt the individual layer pipeline, under the lower situation of outside air temperature, makes easily that the liquid naphthalene solidifies in the conveyance conduit.
Summary of the invention
The purpose of the utility model just provides a kind of safe and efficient liquid naphthalene transporting system, the problem that the safety coefficient that existing liquid naphthalene transporting system exists is low to solve, the liquid naphthalene is prone to curing in befouling environment and the course of conveying.
The utility model is achieved in that a kind of safe and efficient liquid naphthalene transporting system, includes liquid naphthalene measuring tank, sulfonating reaction still and is connected in conveyance conduit between the two, and said pipeline is a double-skin duct, is connected with Under Water Pumps in the lower end mouth of said double-skin duct.
Adopt Under Water Pumps to carry power is provided, avoided the potential safety hazard of bringing because of high-pressure delivery for the liquid naphthalene; When the liquid naphthalene is carried through double-skin duct, in the outer tube of double-skin duct, can feed steam and be incubated, thus the curing of anti-solution stopping naphthalene.
It is safe and efficient when the utility model uses; Adopt Under Water Pumps to carry the liquid naphthalene; Having eliminated is the security threat that power possibly cause when carrying the liquid naphthalene with pressurized air, and has avoided loss and the environmental pollution of generation therefrom with the liquid naphthalene due to the emptying of sulfonating reaction still; Adopt double-skin duct, the liquid naphthalene is incubated, eliminated curing appears in the liquid naphthalene in course of conveying possibility, improved equipment operating efficiency through the mode that in the outer tube of double-skin duct, feeds high-temperature steam.
Description of drawings
Fig. 1 is the structural representation of the utility model
Among the figure: 1, liquid naphthalene measuring tank, 2, Under Water Pumps, 3, double-skin duct, 4, the sulfonating reaction still, 5, liquid inlet pipe.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, liquid naphthalene measuring tank 1 is connected through double-skin duct 3 with sulfonating reaction still 4, and an end of double-skin duct 3 extend into the inside of liquid naphthalene measuring tank 1, is connected to Under Water Pumps 2 in its port; The another port of double-skin duct 3 extend in the sulfonating reaction still 4.Liquid inlet pipe 5 feeds in the liquid naphthalene measuring tank 1, is its additional liquid naphthalene.
When using liquid naphthalene transporting system to carry the liquid naphthalene, start Under Water Pumps 2, Under Water Pumps 2 pumps into the interior pipe of the liquid naphthalene in the liquid naphthalene measuring tank 1 through double-skin duct 3 in the sulfonating reaction still 4 then.Meanwhile, in the outer tube of double-skin duct 3, feed and flow to opposite high-temperature steam, when high-temperature steam is flowed through outer tube self heat is passed to the liquid naphthalene in the interior pipe, play effect, prevent to solidify the insulation of liquid naphthalene with the liquid naphthalene.
When in the liquid naphthalene measuring tank 1 during liquid naphthalene quantity not sufficient, replenish the liquid naphthalenes through liquid inlet pipe 5.
Claims (1)
1. a safe and efficient liquid naphthalene transporting system includes liquid naphthalene measuring tank, sulfonating reaction still and is connected in conveyance conduit between the two, it is characterized in that said pipeline is a double-skin duct, is connected with Under Water Pumps in the lower end mouth of said double-skin duct.
