Problems solved by technology

Using this method for heat preservation, it is necessary to completely destroy the protective layer and insulation layer before removing it during the maintenance of the steam turbine, resulting in a large amount of waste, causing a lot of waste and serious pollution of the environment, and it is also determined that it is limited to one-time use. Higher cost of use

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings: the thermal insulation method of the present invention, it is to make a certain number of block thermal insulation blankets first according to the surface shape and size of the cylinder shell, and lay a piece of thermal insulation blanket on the steam turbine shell. At least two thermal insulation layers are formed on the surface.

[0019] The formation of the thermal insulation layer is as follows: first laying a thermal insulation layer spliced ​​by a block-shaped thermal insulation blanket on the surface of the steam turbine casing, and then splicing a layer of thermal insulation layer composed of the same or different block thermal insulation blankets on it, And when the upper insulation layer is spliced, the upper insulation blanket covers the connection gap formed between the two insulation blankets in the lower insulation layer, and the upper and lower layers for...

Abstract

The present invention relates to a turbine cylinder baffle heat-insulating method and its heat-insulating layer. It is characterized by that according to the surface from and size of cylinder baffle a certain quantity of block-shaped heat-insulating blanket can be made up, then these block-shaped heat-insulating blankets are laid on the surface of cylinder baffle one block-by-one block so as to form at least two layers of heat-insulating layers. Its structure is simple, and its heat-insulating effect is good.

Description

technical field [0001] The invention relates to a method and device for heat preservation of a steam turbine cylinder casing, in particular a detachable combined heat preservation method and device, which belong to the technical field of equipment heat preservation and protection. Background technique [0002] With the extensive use of large-scale equipment, its operation at high or low temperatures often results in a large loss of heat or cooling, such as steam turbine generator sets. These equipment operating at high temperature often have their shells exposed to the space, resulting in a large amount of heat loss. If these large equipment are operated in winter or in cold places in the north, the heat loss will be extremely considerable, which not only affects the energy utilization rate of the equipment. High and low, but also affect the efficiency of equipment operation, greatly increasing the cost of operation. [0003] Although there are some conventional heat preser...
