Problems solved by technology
[0003] In the prior art, when hoisting the refining tower, the method of hoisting the refining tower first and then installing the parts on the refining tower is generally used to hoist the small or multi-stage refining tower. (Generally weighing up to 200 tons) When hoisting the refining tower, it is hoisted first, and then when climbing the refining tower to install the components on the surface, it is not only inconvenient to operate, but also laborious and laborious. In addition, the risk of working at heights is extremely high

The invention belongs to the technical field of refining towers, and particularly relates to a hoisting method of a refining tower, which comprises the following steps of: firstly, cleaning a construction site, completely cleaning obstacles on a transportation route of the refining tower, arranging the construction site, and presetting five saddles on the construction site, foundation treatment is conducted on areas of the five saddles, site leveling and compaction are conducted on a main device area through an excavator before equipment enters a site, foundation reinforcement needs to be conducted on part of areas on a driving route, and recovery is conducted after the equipment is unloaded. According to the hoisting method of the refining tower, aloft work is reduced, the construction cost is reduced, the aloft work amount is completed on the ground, safety and reliability are achieved, unsafe factors are reduced to the minimum, all installation work amounts of the tower body are completed at a time, and efficient hoisting of the refining tower is achieved.
Description
technical field [0001] The invention relates to the technical field of refining towers, in particular to a method for hoisting the refining towers. Background technique [0002] The refining tower is a tower-type gas-liquid contact device for refining. Utilizing the different volatility of each component in the mixture, that is, the property that the vapor pressure of each component is different at the same temperature, the light components (low boilers) in the liquid phase are transferred to the gas phase, while the gas phase The heavy components (high boilers) are transferred to the liquid phase, thus achieving the purpose of separation. The refining tower is also a mass transfer and heat transfer device widely used in petrochemical production. [0003] In the prior art, when hoisting the refining tower, the method of hoisting the refining tower first and then installing the parts on the refining tower is generally used to hoist the small or multi-stage refining tower. ...
