Construction process for constructing prilling tower spraying layer by slide mold device dragging construction platform

Abstract

The invention provides a construction process for constructing a prilling tower spraying layer by a slide mold device dragging a construction platform. The construction process solves the problem of construction difficulty of a prilling tower spraying layer. According to the method, a slide mold device for tube wall construction of a prilling tower is used for carrying the construction platform to realize the synchronous sliding ascending, after the construction platform slides and ascends to a position under the prilling tower spraying layer, the construction platform is disengaged from the slide mold device for constructing the tube wall of the prilling tower spraying layer, in addition, the construction platform is fixed to a corbel pre-buried in the tube wall, then, the slide mold device of the tube wall continuously and upwards slides and ascends for completing the construction of the tube wall, after the tube wall construction is completed, the construction platform is used, and in addition, a tower crane is matched for vertically conveying and constructing the spraying layer. When being used for constructing the prilling tower spraying layer, the method has the advantages that the construction is simple and convenient, a great amount of turnover materials are saved, the use of a large-scale crane and a large-scale hoisting machine is avoided, the cost is reduced, the economic benefits are good, and the operation platform is adopted, so that the high-altitude construction safety is well ensured. The method also obtains a good effect in practical application, and in addition, the method wins good reputation from owners.

Description

technical field

[0001] The invention relates to a new construction technique for the spray layer of a granulation tower, in particular to a construction technique for constructing the spray layer of a granulation tower by dragging a construction platform with a sliding-form device. Background technique

[0002] In recent years, due to the rapid development of China's economy, the pressure on the environment is increasing. In order to slow down the damage to the environment, the state vigorously advocates circular economy. Therefore, the urea-to-ammonia plant, which can be recycled as an accessory product of the coking unit, has been vigorously developed in recent years, and many urea-to-ammonia plant projects are under construction every year. The prilling tower is the core device in the urea production process. The structure of the granulation tower is a reinforced concrete silo structure, and the spray layer is a platform located on the upper part of the granulation tower...
