Embodiment 1

[0027] refer to Figures 1 to 2 As shown, the auxiliary starting device for hot waxy crude oil pipeline of the present invention includes: vehicle frame 2, liquid storage tank 3, reaction tank 4, control system 8 and propulsion system, and the propulsion system is installed on the vehicle frame 2 for pushing the vehicle Rack 2 moves. The liquid storage tank 3 and the reaction tank 4 are respectively equipped with reactants for the reaction to generate gas, that is, the liquid storage tank 3 is used to contain the liquid first reactant, and the reaction tank 4 is used to contain the second reactant. The reactant and the second reactant can react to form a gas. The liquid storage tank 3 and the reaction tank 4 are installed on the vehicle frame 2 respectively, and the liquid storage tank 3 is higher than the reaction tank 4, and the liquid storage tank 3 and the reaction tank 4 are communicated through a conduit 6, and one end of the conduit 6 is connected to the liquid storage...

Embodiment 2

[0041] This embodiment is basically the same as Embodiment 1, except that the wheel mechanism of this embodiment adopts 4 wheels, and the 4 wheels are arranged in a rectangular shape at the lower position of the vehicle frame.

Abstract

The invention relates to the pipeline safety technical field, and discloses a hot wax-bearing crude oil pipeline auxiliary starting device comprising a vehicle frame, a reservoir, a reaction tank, a control system and a propulsion system; the propulsion system is arranged on the vehicle frame and used for pushing the vehicle frame to move; the reservoir and the reaction tank are respectively arranged on the vehicle frame; the reservoir is higher than the reaction tank; the reservoir is connected with the reaction tank through a pipe; the pipe is provided with a cut off valve; the reservoir and the reaction tank are respectively provided with reactant used for gas generation by reaction; the reaction tank is provided with a gas outlet allowing gas to flow out; the control system is respectively connected with the propulsion system and the cut off valve. The vehicle frame is provided with the reservoir and the reaction tank filled with reactants for gas generation; the reservoir and the reaction tank are isolated by the cut off valve; when the crude oil pipeline is started and the cut off valve is opened, the reservoir and the reaction tank are connected, so the reactants can react to form gas, thus fast raising pipeline pressure, so gelling crude oil in the pipeline can rupture, and the pipeline can be re-conducted, thus improving pipeline restart success rate.

Description

technical field [0001] The invention relates to the technical field of pipeline safety, in particular to an auxiliary starting device for hot waxy crude oil pipeline. Background technique [0002] Planned and accidental outages are inevitable production processes in the operation of hot waxy crude oil pipelines. If the repair time of the pipeline is too long after the suspension of transportation, the temperature of the oil in the pipeline will drop greatly, which may lead to a "pipe condensation" accident and cause major economic losses. Therefore, it is necessary to design a pipeline auxiliary start-up device to improve the success rate of pipeline start-up, ensure the safety of pipeline operation, and reduce the economic losses caused by accidents. [0003] The temperature distribution law of the hot oil pipeline is: from the head end (outbound) to the end (incoming), the temperature inside the pipe gradually decreases. Under normal circumstances, when the hot oil enters...
