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.

Example 1

Referring to fig. 1, a constant temperature storage system for a surfactant comprises a sealed storage tank 1, and further comprises a temperature control unit and a circulation pump 2 which are arranged outside the storage tank 1, wherein a heat preservation jacket 3 is arranged on the storage tank 1, the storage tank 1 is further connected with an inert gas replacement unit for maintaining an inert gas environment of the storage tank 1, the circulation pump 2 and the temperature control unit form a circulation loop, the temperature control unit is connected with the side wall of the storage tank 1 through at least one circulation pipeline 4, and the circulation pipeline 4 is tangent to the side wall of the storage tank 1.

The reason why the temperature control unit is arranged outside the temperature control unit and the circulating pipeline 4 is tangent to the side wall of the storage tank 1 in the embodiment is that most of the surfactant has relatively poor flowability, and if the traditional jacket heating mode is adopted, the surfactant in the tank has a relatively obvious temperature difference from outside to inside, and the phenomenon is more obvious particularly in the temperature regulation process. In this embodiment, adopt circulating pump 2 to take out pulpous state surfactant form to the accuse temperature unit, circulate in storage tank 1 after carrying out temperature control to surfactant form, though the mobility of surfactant form is relatively poor, compare the mode of traditional stationary heating with the tangent circulation pipeline 4 of lateral wall and continue tangential input surfactant form, the heat balance nature of its material is better, can form a little flow system in storage tank 1.

Preferably, temperature sensors are arranged at different heights of the inner wall of the storage tank 1, the central position of the storage tank 1 and the like, so that production personnel can accurately know the production state on site.

Preferably, the temperature control unit is connected with the side wall of the storage tank 1 through three or more circulating pipelines 4; at least one circulation pipe 4 is connected to the middle portion of the storage tank 1, at least one circulation pipe 4 is connected to the lower portion of the storage tank 1, and at least one circulation pipe 4 is connected to the middle lower portion of the storage tank 1. Each circulation pipe 4 can be provided with a valve independently. Through the plurality of circulation pipes 4, the slow flow of the fluid in the whole tank body can be promoted from top to bottom.

Preferably, the temperature control unit comprises a temperature control container 5 and a serpentine pipeline 6 arranged in the temperature control container 5, wherein one end of the serpentine pipeline 6 is connected with an outlet of the circulating pump 2, and the serpentine pipeline 6 is connected to the storage tank 1 through the circulating pipeline 4; the temperature control container 5 is provided with a temperature control medium inlet 7 and a temperature control medium outlet 8, and the temperature control medium injected into the temperature control container 5 is water or oil with a preset temperature. The inlet of the circulation pump 2 is connected to the bottom of the storage tank 1. The diameter of the serpentine pipeline 6 is about 5-10cm, and a temperature control medium inlet 7 and a temperature control medium outlet 8 are respectively arranged at the lower part and the upper part of the temperature control container 5; the temperature control container 5 is a flat upright box.

Preferably, the inert gas replacement unit comprises a gas supply pipe 9, a first branch pipe 10 and a second branch pipe 11 connected with the gas supply pipe 9, the first branch pipe 10 is connected to the top of the storage tank 1, and the second branch pipe 11 is connected to the bottom of the storage tank 1; the top of storage tank 1 is equipped with the blast pipe 12 of being connected with the exhaust-gas treatment equipment of peripheral hardware, all be equipped with the valve on first branch pipe 10, second branch pipe 11, the blast pipe 12. The second branch pipe 11 is used for replacing oxygen in the slurry by injecting nitrogen into the slurry, the first branch pipe 10 is used for maintaining an inert environment of an upper space, as a refinement of the embodiment, a feeding pipe 13 is arranged at the top of the storage tank 1, and a discharging pipe 14 and a discharging pump 15 are arranged at the bottom of the storage tank 1.

As an alternative method, the above-mentioned circulation pump 2 and discharge pump 15 are reduced to 1 pump, i.e. the discharge pipe 14 at the bottom of the storage tank 1 is connected to the pump, and the outlet of the pump is connected to the outside and the serpentine pipe 6, which has the advantage of reducing the equipment, and has the disadvantage that temperature control during discharge causes a lower partial pressure and a too slow temperature adjustment speed, but this requires fewer temperature controls at the side of the general discharge, and is therefore a feasible and preferred method.
