Problems solved by technology

[0003] The existing gas pipeline system has a complex structure, is not easy to install, and the distribution of the scavenging ports is unscientific, resulting in incomplete removal of harmful gases inside the spud can
In addition, the existing gas pipeline system is poor in safety and lacks relevant monitoring and monitoring equipment. Harmful gas removal operations can only rely on experience, and it is difficult to reasonably arrange operation time, resulting in waste of resources, harmful gas residues, and excessively high air temperature inside the spud boots. question

Embodiment Construction

[0024] A harmful gas blowing system for offshore platform spud cans proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and use imprecise ratios, which are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0025] Such as Figure 1-Figure 2 As shown, the present invention proposes a harmful gas blowing system applied to the spud can of the offshore platform. The spud can of the offshore platform includes six cabins 5, and the deck of the spud can of the offshore platform is provided with a main exhaust port. And each cabin is provided with a sub-exhaust port 501; the harmful gas blowing system includes a gas pipeline system 1, an air delivery...

Abstract

The invention discloses a harmful gas blowing system applied to spud shoes of offshore platforms, comprising: an air delivery system, a gas delivery pipeline system, a monitoring device and a PLC controller, and the gas delivery pipeline system is used to deliver compressed gas Go to various places inside the spud can of the offshore platform to increase the air replacement rate inside the spud can of the offshore platform, and the PLC controller is used to control the working state of the air conveying system according to the concentration of harmful gases inside the spud can of the offshore platform. The invention has simple structure, easy installation, can realize intelligent operation, and has great economic value and social benefit.

Description

technical field [0001] The invention relates to an offshore platform spud can, in particular to a harmful gas blowing system applied inside the offshore platform spud can. Background technique [0002] During the working process of spud boots on offshore platforms, some harmful gases such as hydrogen sulfide and carbon monoxide (the maximum concentration of the mixed gas is 55PPM) will remain in the interior, which brings great difficulties to repair and maintenance work. In order to reduce the concentration within a limited time Within the safe range, it can generally be realized by air replacement: that is, the fresh air (compressed air) is transported to the interior of the cabin through the gas pipeline to dilute the harmful mixed gas containing hydrogen sulfide and carbon monoxide. , the mixed gas flows in the cabin, the pressure in the cabin will increase with the increase of the intake volume, the harmful gas in the cabin will be discharged out of the cabin with the m...
