The application provides a method for removing oxygen-containing compounds from Fischer-Tropsch naphtha, which comprises the following steps: (1) reacting Fischer-Tropsch naphtha, a catalyst, isopropyl alcohol and glycol in a stirring reactor, and then standing and separating; (2) extracting the upper hydrocarbon phase after standing with an extractant to obtain an extraction phase and a raffinate phase; (3) recovering the solvent in a solvent recovery column, obtaining oxygen-containing compounds at the top of the column, and recycling the solvent obtained at the bottom of the column as the extractant; (4) washing the raffinate phase with water to obtain Fischer-Tropsch naphtha from which the oxygen-containing compounds are removed and washed water, recycling the washed water to the water washing column for water washing, and recycling the product at the bottom of the water recovery column as the extractant; the extractant is a mixture of ester compounds and glycol compounds, and the content of the glycol compounds is 40-70%; and the method can reduce the oxygen-containing compounds in the Fischer-Tropsch naphtha to 5 ppm, and the oil recovery rate reaches more than 95%.

The utility model discloses a driving mechanism which is arranged in a second space formed by a shell and a lower sleeve body and comprises a rotary body, a pipe frame, a push rod, a spring and an actuating piece. The rotary body is rotationally arranged on the inner side of the shell, and the rotary body partially extends into the lower sleeve body and is connected with the lower sleeve body; the pipe frame is arranged on the inner side of the rotary body, rotates along with the rotary body all the time and can only move up and down in the axial direction of the rotary body. The push rod extends to the position above the shell from the pipe frame and is used for applying thrust to a target object; the spring is arranged below the pipe frame; the actuating piece is arranged above the rotary body and can reciprocate in the shell in the radial direction; the driving mechanism is convenient to operate, more stable pushing force can be provided by using a spring instead of a lifting handle, the atomization effect of the device is remarkably improved, the consistency of each spraying of the device is good by using a disposable medicine bottle to be matched with stable pushing force output, and daily precise medicine taking of a patient is facilitated.

The utility model relates to sample information management device technical field, especially based on the replaceable hinge of photo's sample information collection board, sample information collection board includes the sample placement area in upper portion to replaceable hinge area in lower portion, replaceable hinge area includes the multiple placement grooves of being opened in sample information collection board lower part, the mark hinge is set with through the mode of magnetic attraction in the placement groove. The utility model can replace the mark hinge, so that sample information collection board can be reused.

The utility model discloses neutral water step-by-step quantitative purifying and recycling equipment which comprises a shell, a liquid storage bin is arranged in the shell, a first electromagnetic valve is arranged at the bottom in the liquid storage bin, a first driving motor is arranged on one side of the liquid storage bin, and a rotating rod is arranged at the output end of the first driving motor; a plurality of sets of outer sleeves are evenly arranged on the outer side of the rotating rod, stirring rods are symmetrically arranged at the tops and the bottoms of the outer sleeves, a control assembly is arranged on one side of the liquid storage bin, a liquid discharging pipe is arranged on one side of the interior of the shell, and a liquid control assembly is arranged at the bottom of one side of the liquid discharging pipe. Under the cooperation of the filter screen, the liquid passing bin, the second electromagnetic valve, the connecting pipe, the push plate, the rotating shaft, the discharge hole and the second driving motor, particle impurities in reclaimed water can be filtered in the reclaimed water recycling process, so that the subsequent purification work is ensured, and the working efficiency is improved. And the separated solid particles can be automatically discharged to the outside to ensure the filtering effect.

This invention provides an auxiliary system and construction method for positioning and installing lattice columns. The auxiliary system includes a guide frame and a positioning mechanism. The guide frame can be nested and inserted into the lattice column and is detachably connected to it. The guide frame includes a positioning frame and multiple first positioning blocks fixed to the outside of the positioning frame. The positioning mechanism controls the center deviation and verticality of the lattice column by adjusting the center deviation and verticality of the guide frame. The positioning mechanism includes a hollow rectangular frame, four jacks installed at the bottom of the four corners of the rectangular frame, and an adjustment mechanism for adjusting the orifice size through which the guide frame passes. The orifice is located within the rectangular frame, and its size matches the size of the positioning frame. The multiple first positioning blocks are located on and abut against the rectangular frame. By using this auxiliary system to install lattice columns, the positioning difficulty of ultra-long hollow lattice columns is reduced, the positioning operation time is effectively shortened, and the positioning effect is stable and reliable.

The invention relates to a device and method for lifting water through buoyancy. The device comprises a first water storage barrel and a second water storage barrel. The first water storage barrel is provided with a first water inlet device, a first drainage device and a first air bag; the second water storage barrel is provided with a second water inlet device, a second drainage device and a second air bag; the first airbag is connected with the second airbag through an air pipe; an air valve and an air extractor are arranged on the air pipe; when the air extractor sucks air into the first air bag to push the first water storage barrel to drain water, the second water storage barrel descends to store water, and high-pressure air is stored in the first air bag; after drainage of the first water storage barrel is completed, water storage of the second water storage barrel is also completed, an air valve is opened, high-pressure air enters the second air bag, the second water storage barrel is pushed up, after air pressure is balanced, an air extractor is started, air is extracted into the second air bag, when the second water storage barrel is pushed up to drain water, the first water storage barrel descends to store water, and the steps are repeated to lift water. The device has the advantages of being simple in structure, improving the energy utilization rate and saving energy.
