Device applicable to pipe washing work of deep sea oil and gas pipeline

InactiveCN110252750AOvercome stressOvercoming resistance along the wayHollow article cleaningPiggingPore water pressure
The invention discloses a device applicable to a pipe washing work of a deep sea oil and gas pipeline. The device comprises a water flushing system, a chemical agent filling system which is connected to the water flushing system, an assisting system which assists the water flushing system to clean the pipeline, and a data acquiring and transmitting system for acquiring and transmitting data of a pipe cleaning device, wherein the water flushing system comprises at least free water flushing and ROV supported water flushing; the free water flushing is that the inner and outer water pressure difference of a seawater pipeline is treated as power to flush water for cleaning the pipe; the ROV supported water flushing is that hydraulic power supplied by a centrifugal pump is used for flushing water to clean the pipe; the chemical agent filling system comprises at least an underwater chemical agent tank, a chemical agent discharging assembly, a chemical agent filling assembly, a chemical agent filtering and adjusting assembly and an underwater rapid chemical agent supplementing joint; and the chemical agent is filled with different concentration and mixing ratio through the chemical agent filling and adjusting assembly based on the flow rate change of a main pipeline. The device overcomes deep water pressure and resistance along the way and reduces the shortages of a large amount of aboveground devices for normal pipe cleaning work, large occupied space, and high input cost; and the deep water pipeline cleaning work efficiency is improved.

Method and structure for co-processing waste incineration fly ash underground in mine

ActiveCN114160542AAlleviate resource constraintsAlleviating the Nowhere to Dispose ProblemSolid waste disposalTransportation and packagingEnvironmental engineeringCement mortar
The invention provides a method and structure for co-processing waste incineration fly ash underground in a mine. According to the method, anti-pollution and anti-seepage treatment of the mine is used as a first-stage pollution isolation barrier; a secondary dirt isolation barrier is formed through encapsulation treatment; and clay mortar in the treatment sealing layer is used as a third-stage dirt isolation barrier. According to the structure, an underground space of a mine serves as a fly ash disposal space, and a wall impermeable layer is arranged in the fly ash disposal space; a plurality of packaging box body stacks are placed in the fly ash disposal space, and each packaging box body stack is formed by stacking a plurality of packaging box bodies; the encapsulation box body comprises a box body, a chelating agent or a chemical agent fly ash mixture is contained in the box body, and the top of the box body is sealed through a cement mortar layer; a disposal sealing layer is arranged at the outlet position of the fly ash disposal space, and the fly ash disposal space among the multiple packaging box body stacks is filled with clay mortar. The problems that ground land resources are short and waste incineration fly ash cannot be disposed can be effectively relieved. And underground idle space formed after coal mining can be effectively utilized.

Novel chemical agent injection device

PendingCN111677894ARealize interchangeabilityRealize the realization of interchangeable universalFlanged jointsSlide valveEngineeringMechanical engineering
The invention provides a novel chemical agent injection device. The novel chemical agent injection device comprises a reducing pipe and an injection part which are sequentially arranged from top to bottom, the inner diameter of the bottom of the reducing pipe is the same as that of the top end of the injection part, the upper end of the reducing pipe is sleeved with a first flange, the lower end of the reducing pipe is sleeved with a second flange, and the injection part comprises an injection joint and a pipe body, a third flange is sleeved below the injection joint, the second flange is fixedly connected with the third flange through a bolt, an upper sealing gasket is padded between the injection joint and the second flange, a lower sealing gasket is padded between the injection joint and the third flange, a medicine feeding hole is formed in the side wall of the bottom of the pipe body, and a short pipe and a pipe seat are sequentially sleeved on the pipe body from top to bottom. According to the novel chemical agent injection device, the interchange and universality of injection parts with the same pressure grade are realized, and when the injection parts are better, the operation can be finished by only detaching the flange connection and re-fastening the flange connection after replacement, so that the operation is convenient, and standardized, serialized and mass production can be realized.

Anti-oxidation surface treatment method for conductive bar

The invention relates to the field of conductive bar production, in particular to an anti-oxidation surface treatment method for a conductive bar. The anti-oxidation surface treatment method comprisesthe following steps of 1, soaking the conductive bar to be treated in a cleaning solution to remove oil stains and rust on the surface of the conductive bar; 2, cleaning the cleaned conductive bar with deionized water, and wiping the conductive bar with a wiping cloth; 3, placing the dried conductive bar in a solvent containing an antioxidant, heating the conductive bar to 50-200 DEG C, and carrying out sealed and pressurized reaction; and 4, after the treatment is finished, cleaning and then drying the conductive bar at a low temperature. By adopting a chemical agent blending, heating and pressurizing treatment method, the process is simple, little pollution is caused, and the process is controllable.
