4results about How to "Short replacement cycle" patented technology

The invention discloses an anti-leakage spray condensation device with a nozzle capable of being replaced on line. The anti-leakage spray condensation device comprises an upper rapid switching blind plate valve, a lower rapid switching blind plate valve, an annular nitrogen injection port, a detachable nozzle, a nitrogen injection port at the blind plate valve and a labyrinth sealing pipe. The detachable nozzle is inserted into the labyrinth sealing pipe in a sleeve mode, and the insertion end is connected through a flange. According to the anti-leakage spray condensation device capable of replacing the spray head online, on the premise that safety is guaranteed, rapid and online replacement of the spray head can be achieved, and the maintenance cost and the risk of production interruption are greatly reduced. Through the design of the two-stage quick switching blind plate valve, the sealing performance of a pipeline system in the replacement process is ensured; the nitrogen injection device provides necessary safety guarantee; and due to the design of the detachable spray head, the maintenance convenience is improved. By implementing the technical scheme, the safety and economical efficiency of pyrolysis gas treatment can be remarkably improved.

The invention belongs to the field of oil and gas field equipment, and discloses a gas storage gas injection compressor degreaser with a pipe insertion type filter element, which comprises a barrel, a support plate is arranged in an inner cavity of the barrel, an oil guide pipe is arranged on the support plate, an inlet pipe is arranged on the barrel at a primary separation cavity, and a blow-off pipe is arranged at the bottom of the barrel; a filter element assembly is arranged at the upper part of the supporting plate in the barrel, a through hole for enabling a gas-liquid mixture to flow into the filter element assembly is formed in the supporting plate, and an outlet pipe is arranged at the position, above the filter element assembly, of the barrel; the filter element assembly comprises a filter unit, the filter unit comprises a supporting pipe and a filter layer fixedly arranged outside the supporting pipe in a sleeving mode, the supporting pipe extends to the top of the filter layer from the bottom of the filter layer, a plurality of filter holes are formed in the area, corresponding to the filter layer, of the supporting pipe, and the top of the filter layer and the top of the supporting pipe are closed. According to the invention, gas can uniformly flow out from the pores of the supporting pipe in the filtering process, so that the filter element is fully utilized.
