2results about How to "Reduce oil pollution" patented technology

The invention provides oil-based drilling cutting-based fluid-state solidified soil as well as a preparation method and application thereof, and belongs to the technical field of fluid-state solidified soil. The oil-based drilling cutting based flow state solidified soil is prepared from the following raw materials: 100 parts of pretreated oil-based drilling cutting, 10 to 15 parts of a composite curing agent, 1 to 3 parts of polymer latex, 2 to 4 parts of rubber particles, 0.2 to 0.4 part of basalt fiber, 0.5 to 1 part of magnesium oxide, 0.2 to 0.5 part of a flocculating agent, 0.4 to 0.6 part of a water reducing agent and 60 to 80 parts of water, the pretreatment method of the oil-based drilling cuttings comprises the following steps that the oil-based drilling cuttings are subjected to heat treatment after being subjected to preliminary dehydration; then, uniformly mixing the oil-based drilling cuttings subjected to heat treatment with quick lime and an ionic salt solution, and carrying out braising treatment; and then adding activated carbon and wood chips, and stirring at normal temperature for reaction to obtain the pretreated oil-based drilling cuttings. The oil-based drilling-cutting-based fluid-state solidified soil has good fluidity and excellent compressive strength and crack resistance, the problems that oil-based drilling cuttings occupy land and pollute the environment after being piled up for a long time are solved, and resource utilization of waste materials is achieved.

The utility model relates to an exhaust circuit oil removal structure of a food vending machine, which comprises a casing, a first filter screen is arranged in the casing, the casing is divided into a first air cavity and a second air cavity by the first filter screen, the first air cavity is provided with an air inlet, and a high-pressure oil smoke removal mechanism is arranged in the second air cavity. The high-pressure oil smoke removing mechanism comprises two end plates and a conductive pipe, the two ends of the conductive pipe are connected to the two end plates in a one-to-one correspondence mode, the second air cavity is divided into an air inlet chamber, a middle chamber and an air outlet chamber through the two end plates, the air inlet chamber and the air outlet chamber are communicated through the conductive pipe, and the air outlet chamber is provided with an air outlet. And a high-voltage electrode is hung in the conductive tube. The utility model aims to provide the air exhaust path oil removal structure of the food vending machine, which can remove oil fume in steam, and solves the problem that the existing food vending machine directly discharges the steam containing the oil fume to cause serious environmental pollution.
