The utility model relates to the technical field of pipe fittings, in particular to a liquefied natural gas pipeline installing and positioning assembly which comprises a connecting disc, the connecting disc is installed between two liquefied natural gas pipelines, flanges are fixed to the ends of the liquefied natural gas pipelines, a plurality of screws are fixed to the two sides of the connecting disc respectively, and rubber sleeves are arranged on rod bodies of the screws in a sleeved mode. One end of the screw rod is sleeved and screwed with a nut, the outer ring surface of the connecting disc is provided with a rubber cover, and the rubber cover wraps the flange; the device has the beneficial effects that the rubber cover arranged on the outer ring surface of the connecting disc can wrap and protect the screw rod and the nut. After the screw rod and the nut are in threaded connection, the rubber cover is pulled out of the containing groove and arranged on the flange in a sleeving mode, the rubber ring is arranged at the connecting position of the liquefied natural gas pipe and the flange in a sleeving mode, erosion of external water vapor to the screw rod and the nut can be effectively reduced, the service life of a connecting part is prolonged, and the maintenance cost is reduced.

The utility model relates to the field of waste gas treatment technology of thermal power plant discloses a kind of waste gas purification environmental protection device of thermal power plant, including the frame for waste gas treatment, the outside fixed connection of frame has the air intake assembly for air intake, the inner chamber fixed connection of frame has the steam heat exchange mechanism for steam heat exchange, the bottom end fixed connection of frame has the material return plate for discharging, the bottom end fixed connection of material return plate has the material collecting mechanism for stacking, the bottom end fixed connection of material return plate has the stand for connection, the bottom end fixed connection of stand has the bottom plate for supporting, heat exchanger can fully absorb the heat in waste gas, realize the recycling of heat, water circulation bin cooperates with heat exchanger, forms water circulation system, steam heat exchange mechanism absorbs the heat in waste gas through heat exchanger, heats the water in water circulation bin, generates steam, realizes waste heat utilization+purification dual effect, reduces external energy consumption.
