Skid-mounted compact air separation plant supporting rack

Abstract

The invention relates to a skid-mounted compact air separation plant supporting rack which comprises cold box frameworks arranged vertically on two sides. The frames are hollow inside. The two frameworks are connected and fixed through a cross beam. The skid-mounted compact air separation plant supporting rack is characterized in that the cross beam is welded to the cold box frameworks on two sides and is vertical to the cold box frameworks, a valve rack supporting rod is arranged above the cross beam, one side of the supporting rod is welded to the cold box frameworks while angle iron is welded to the other side, a plurality of low-temperature valve hoops are arranged on a side surface of the angle iron and are fixed by means of a gasket and a nut arranged at the bottom of the angle iron,a bracket is welded to the angle iron opposite to the inner sides of the low-temperature valve hoops, and a circular fastening ring is formed by the low-temperature valve hoops and the bracket to fixthe valve. By designing an integrated valve rack of the integral skid-mounted compact air separation plant supporting rack, the space occupancy of the valve rack in the cold box can be reduced effectively, the inner arrangement space of the cold box is optimized, and the design standardized level and the mounting and manufacturing quality of the valve rack are improved.

Description

technical field [0001] The invention relates to a skid-mounted compact air separation equipment support frame, which belongs to the technical field of air separation equipment. Background technique [0002] The standardized and compact air separation plant adopting the overall skid-mounted technology is the main demand of the medium-sized air separation plant market at present, and is an important technical index of the advanced medium-sized air separation plant. Compared with the delivery method, it can greatly reduce the workload of engineering installation on the user's site and reduce the difficulty of management, which helps to shorten the construction period and ensure product quality, and ultimately saves engineering costs. [0003] The overall skid-mounted compact air separation plant, like other air separation plant cold box systems, also includes rectification towers, condensing evaporators, heat exchangers, valves, pipes, various supports and hangers, cold box she...

Problems solved by technology

[0003] The overall skid-mounted compact air separation plant, like other air separation plant cold box systems, also includes rectification towers, condensing evaporators, heat exchangers, valves, pipes, various supports and hangers, cold box shells, and cold boxes. However, affected by limiting factors such as factory manufacturing level, road transportation conditions and on-site large-scale equipment installation capacity, the internal installation space of the cold box is very limited, and all the parts (pieces) in the cold box must be installed ) for continuous optimization and innovation, the skid-mounted compact air separation plant support frame can effectively reduce the space occupancy of the valve frame in the cold box, optimize the internal layout space of the cold box, and improve the standardization level of valve frame design and installation and manufacturing quality
