The invention relates to a UV photolysis air purification device with dust removal function, which includes a main body, an air inlet pipe, an air outlet pipe and a UV lamp, and also includes a dust removal mechanism and a heat dissipation mechanism. The dust removal mechanism includes a dust removal box, a filter cartridge, a hose, Connecting pipe, power assembly, ring, two limit assemblies, two impurity removal assemblies and several struts, the heat dissipation mechanism includes a sponge, a collection box, a fixed box, a pumping assembly, a connection box and two water spray assemblies, The UV photolysis air purification equipment with dust removal function realizes the function of dedusting the exhaust gas through the dust removal mechanism, preventing the dust in the exhaust gas from covering the UV lamp and affecting the waste gas treatment work of the UV lamp, and spraying on the sponge through the heat dissipation mechanism Clean water can cool down the surrounding air, thereby cooling down the UV lamp, preventing the UV lamp from being damaged due to overheating, and improving the reliability of the equipment.

The invention relates to a method and an apparatus for recovery of remaining alumina and dust collection in alumina discharge stations. According to the invention, a negative pressure dust collection system and a fixed type design are employed; main equipment is installed in a central material knockout platform of a discharge station; power for negative pressure is generated by a Roots pump; a gathered material obtained through a material gathering nozzle is conveyed by a wear resistant flexible pipe and a wear resistant pipe network and subjected to three-stage separation of interception by a material storing bunker, separation by a cyclone dust collector and separation by a bag filler; recovered alumina is screened by a flap sieve and returned to a railway alumina tank car which is empty or half-empty after material knockout; and an alumina discharge station dilute phase system is used to convey the recovered alumina to an alumina storing bunker. The advantages of the invention are as follows: the problems of multi-time turning of vehicles, multi-time rising of alumina and incapability of removing impurities in stained alumina on the floor existing in manual digging and manual sweeping of alumina are overcome; valuable resources are recovered; waste is reduced; labor intensity of workers are mitigated; working environment is improved; working efficiency is enhanced; clean production is realized. Therefore, the apparatus provided is applicable to electrolytic aluminum factories, alumina factories, alumina loading and unloading stations and harbors.

The invention relates to the technical field of natural gas synergistic processing equipment, and particularly relates to a preposed condensation impurity removing device for adding a natural gas synergistic additive. A natural gas pipe is a square pipe; the lower pipe wall of the natural gas pipe is provided with an inlet hole and an outlet hole; a condensation ring is a circular ring; the upperpart of the condensation ring extends into the natural gas pipe through an inlet hole and an outlet hole; the top of the condensation ring is close to the top of the natural gas pipe; condensation ring supporting rollers are arranged under the condensation ring and are used for supporting the lower edge of the condensation ring; condensation ring positioning rollers are arranged in a condensationring circle and are matched with the condensation ring supporting rollers to clamp the condensation ring, and positioning is realized; and a plurality of condensation ring excitation electromagnets are uniformly distributed around the part, outside the natural gas pipe, of the condensation pipe. According to the invention, a condensation ring circulation working principle of a demagnetization refrigeration principle is adopted, so that an impurity removing effect on impurities such as water vapor, volatile gaseous long-chain hydrocarbon and the like in natural gas is realized, and the productquality stability after operation of follow-up natural gas additive is effectively improved.

The invention relates to the technical field of battery piece etching, and particularly relates to a solar panel etching process for preventing the EL pollution. The process comprises the steps that in step 1, plating film is prepared, a layer of aluminum film is plated on both the upper and lower surfaces of the to-be-etched silicon wafer; in step 2, primary removal of impurities is conducted; in step 3, secondary removal of impurities is conducted, then the film is soaked in a primary etching liquid; in step 4, the remaining aluminum film is removed; in step 5, etching is prepared; and in step 6, etching is conducted. Through the effect of aluminum film, and oxygen and variable temperature heating at the primary removal of impurities, the removal of impurities on silicon wafer is achieved, then through the reaction role of the primary etching liquid and aluminum film at the secondary removal of impurities, the aluminum film is made to further adsorb the impurities inside the silicon wafer, to better achieve the function of removing impurities for silicon wafer, in the wafer etching process, through the function of the primary removal of impurities and the secondary removal of impurities, EL pollution is effectively prevented while etching, the producing of electric leakage battery boards and hidden crack battery boards is reduced and very effective.
