The invention belongs to the technical field of associated gas condensate recovery, and particularly relates to a skid-mounted crude oil associated gas condensate recovery system and a recovery method. The recycling system comprises a skid seat, an equipment body arranged on the skid seat, a secondary liquid separation device and a condensate liquid recycling device, the equipment body comprises a gas-liquid separation device, a liquid separation bag is arranged at one end of the equipment body, an outlet of the liquid separation bag is communicated with an air cooling device, an outlet of the air cooling device is communicated with the secondary liquid separation device, and the equipment body is communicated with an external conveying pipeline; the secondary liquid separation device is arranged at the top of the equipment body and is provided with a partition plate at the lower part. The equipment body and the secondary liquid separation device are separated by the partition plate to form two independent pressure containers, mutual pressure interference is avoided, condensate liquid is collected to a liquid storage tank in the condensate liquid recovery device and then is directly conveyed to an external conveying pipeline through a pump, closed gathering and conveying are achieved, and the energy-saving and environment-friendly effect is achieved. The problems that the associated gas condensate of skid-mounted crude oil pressurizing output equipment is difficult to recover and cannot be conveyed to an output pipeline under pressure are solved.

The utility model belongs to heat exchange technical field, specifically discloses a kind of spoiler, heat exchange device and gas water heating equipment. Spoiler includes long strip's spoiler plate, and spoiler plate is spaced apart with multiple spoiler through holes along length direction, each spoiler through hole has relatively and spaced apart first hole wall and second hole wall, each first hole wall is connected with first spoiler piece, each second hole wall is connected with second spoiler piece, and the projection of first spoiler piece and second spoiler piece corresponding to same spoiler through hole is set on spoiler plate with dislocation;The free end of adjacent two first spoiler pieces is located at the opposite sides of spoiler plate respectively, and the free end of adjacent two second spoiler pieces is located at the opposite sides of spoiler plate respectively. Heat exchange device includes heat exchange pipe and spoiler, and spoiler is inserted in heat exchange pipe. The utility model can improve the spoiler effect of spoiler, and then improve heat exchange uniformity.

This invention relates to the field of cable technology and discloses a composite cross-linked polyethylene insulated cable integrating signal and power transmission. The cable comprises, from the inside out, a composite core, an inner semi-conductive shielding layer, a composite cross-linked polyethylene insulation layer, and an outer semi-conductive shielding layer. The composite cross-linked polyethylene insulation layer is made by extruding and cross-linking raw materials containing the following parts by weight: 90-95 parts low-density polyethylene granules, 5.42-11.6 parts solid premix, and 0.7-2.0 parts liquid co-solution. The solid premix contains N,N'-m-phenylenebismaleimide and tetrabutyl titanate, and the liquid co-solution contains tetramethyltetravinylcyclotetrasiloxane and dicumyl peroxide. This invention anchors by constructing a coordination network, eliminates space charge and micropores in the insulation layer, improves withstand voltage, reduces signal attenuation, and ensures the long-term stability of the integrated power and signal transmission of the composite cable.
