Description

A desulfurization tower maintenance platform

technical field

The invention relates to a maintenance platform for a desulfurization tower.

Background technique

At present, there are hundreds of units above 300MW in my country, all of which are equipped with this desulfurization tower device. The diameter of the tower is about 12-18mm, and there are mortar stirring devices and inlet devices for mortar circulation pumps at the bottom. The elevation is from 2m above the bottom to 20-30m The following is the clear space, the 20-30m above is the mortar main pipe, thousands of branch pipes and nozzles, and the above the mortar pipe is the demisting device. The desulfurization tower is surrounded by steel plate welded structure. For anti-corrosion, glass phosphorus sheet is sprayed on the wall of the tower body around it as anti-corrosion layer, and the upper spray pipe and beam are lined with rubber for anti-corrosion. The equipment will carry out the inspection and repair of the anti-corrosion part of the inner wall of the tower, the maintenance and replacement of the spray pipe and nozzle during the major repair, minor repair and temporary inspection of the furnace. Due to the huge structure of the equipment, the above-mentioned inspection and maintenance is completed by setting up a huge scaffold in the tower body, which is not only labor-intensive, laborious and time-consuming, but also wastes a lot of financial and material resources and prolongs the maintenance period.

Contents of the invention

The invention provides a maintenance platform for a desulfurization tower. The platform has a simple structure and is easy to assemble. At the same time, it can carry workers, maintenance tools and materials to move up and down freely in the tower, and easily complete the maintenance work.

The present invention adopts the following technical solutions: a desulfurization tower maintenance platform, which includes a platform, a platform body, a transmission device and a platform suspension point bracket, a pulley is fixed on the platform suspension point bracket, the platform is located on the top of the platform suspension point bracket, and the platform The platform body is installed in the platform hanging point support; the platform body is composed of transverse beams and longitudinal beams cross-connected, and limit wheels are arranged around the platform body, and the platform body moves in the platform hanging point bracket through the limit wheels. A suspension rope is connected to the body, one end of the suspension rope is connected to the platform body, and the other end is connected to the transmission device after passing through a pulley; the platform is provided with nozzles and lime water pipes, and a demister area is provided on the top of the platform.

The upper end surface of the platform body is fixed with a broken rope protection device, and the lower end surface is provided with reverse support and quick-installation scaffolding, and the broken rope protection device is connected with the suspension rope; the platform body is provided with four broken ropes. Protection device, four pulleys are fixed on the platform lifting point bracket, and each broken rope protection device corresponds to a suspension rope and pulley and is connected to the transmission device; the transverse beam and longitudinal beam are made of superhard aluminum alloy 7A04 profile; the platform body is laid with a springboard; the springboard is a hollow structure 6A02 profile; the transmission device is a hoist, and an overload limit protection device is provided on the hoist; the platform lifting point bracket is an angle steel truss .

The present invention has the following beneficial effects: the present invention is simple in structure, easy to assemble, and has a high safety factor of the suspension rope. At the same time, it can carry workers, maintenance tools and materials together to move up and down freely in the tower, easily complete maintenance work, and has the advantages of saving labor, It is labor-saving and time-saving, and can improve work efficiency by 8-10 times compared with using scaffolding to complete its maintenance. It is fully protected and safe and reliable to use.
