The problem of complex structure, poor dust and tar removal effect, high cost and inconvenient maintenance of the oil-gas separation device in the prior art is solved.

The invention discloses a preparation method and application of a Pt@MOFs / TiO2 optical catalyst. The preparation method comprises the steps that a double solvent method is adopted, firstly noble metal nanoparticles and a prepared MOF organic solvent are subjected to self-assembly, then Pt@MOFs is obtained under the condition that a reducing agent exists, finally TiO2 is evenly dispersed in an aqueous solution of Pt@MOFs, and the MOFs optical catalyst of a three-layer structure is obtained. The prepared optical catalyst can be widely applied to fields of waste water treatment, atmospheric purification and the like. The prepared optical catalyst improves the separation rate of photo induced electron-electron hole, can not only make compounded pollutants separated from each other, but also process the pollutants synchronously and finally improves the photocatalytic efficiency; due to the improvement of the separation rate of photo induced electron-electron hole, the photocatalytic efficiency of the optical catalyst for a single pollutant is also improved.

A coal mine underground gas liquor pressure relief separator mainly comprises a spiral pressure reduction bin 2, a double-layer annular sieve aperture eliminator plate 3, a water and slag collection cylinder 6, an inverted cone cutting type automatic slag discharging outlet 7 and an automatic overflow water outlet 8. A high-pressure gas liquor mixture enters the spiral pressure reduction bin, water and slime sink under the action of a spiral flow deflector, flow into the water and slag collection cylinder, and are discharged through the inverted cone cutting type automatic slag discharging outlet, and an overflow water valve is automatically opened when the water amount is too much; and the upper portion of the spiral pressure reduction bin is connected with the annular sieve aperture eliminator plate, water spray and a gas generated by jetting water are separated, and the gas is introduced to an extraction system through a collection chamber. The separator aims at high pressure water carrying slime and gas, can rapidly reduce the pressure of the gas liquor mixture, and is an automatic device for effectively realizing the separation of coal, water and gas; and the separator makes the gas separated in the cylinder smoothly enter an underground extraction pipeline, can guarantee the safe and efficient running of an extraction system, and can avoid the gas over-limit caused by the entrance of toxic and harmful substances to an underground working surface.

The invention discloses a denitrated flue gas sampling and pretreatment device and belongs to the field of flue gas discharging and collecting devices. The denitrated flue gas sampling and pretreatment device comprises a sampling heating and filtering unit, a back flushing control unit and an ammonium salt rinsing unit, wherein the ammonium salt rinsing unit is connected with a gas outlet of a sampling heating and filtering cavity by a pipeline, and one end of the back flushing control unit is connected with the gas outlet of the sampling heating and filtering unit. The power consumption of equipment is reduced under the conditions that the sampling unit is automatically controlled to heat by the device, and the ammonium salt is not crystalized; NH3 is completely removed to prevent blockage; the ammonium salt adhered to an ammonium salt rinsing bottle and nanometer rinsing balls can be directly rinsed by clear water and can be recycled conveniently, and besides, the back flushing control unit can exert the back flushing effect as expected on a sampling probe and a filter.

The invention relates to a device and method for separating and collecting sand and scum in bottom mud deposits, including a device shell, a self-mixing pipeline type agitator, a lotus-shaped sand settling device, a sand settling secondary separation device, and microporous aeration device and scum flotation unit. When the mixed sediment that needs to be separated is pumped into the pipeline mixer through the feed inlet, it moves downward under the action of gravity and push flow, coupled with the impact of microbubbles from the bottom-micro jet flow, the sediment with a larger specific gravity passes through the pipeline The type agitator enters the lotus-shaped grit settling device to accelerate its deposition at the bottom of the device shell, and then is pumped out through the sand pumping pipe; the sinking mud with a small specific gravity can be discharged through the mud pipe. At the same time as the sand is lifted, due to the turbulent mass transfer of the sinking mud and rising microbubbles, the scum is floated to the scum flotation device above the device for collection. This device realizes the efficient collection of scum in the bottom mud sediment and the separation and recovery of mud and sand, and has the characteristics of simple operation and continuous operation.
