Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing:

[0014] Such as figure 1 Shown is the overall structure diagram of the original construction plan. At present, during the construction of the main chimney 5, the flue gas is discharged through the temporary chimney 1. In order to prevent the flue gas 6 from entering the flue of the main chimney, the baffle door 2 must be closed, and the baffle door 2 will have air leakage. It is necessary to reduce the load or shut down the operator. Install smoke-blocking steel plates 3 and smoke-blocking brick walls 4 into the flue to block. But there will be great risks, such as long construction period and cumbersome procedures, too many potential dangers to personnel, and high economic costs.

[0015] Such as figure 2 Shown is the construction drawing of the air film core body installation. An air film type core body for online sealing of boiler flue in a power plant. The air film ...

Abstract

The invention relates to plugging of a power plant chimney flue, in particular to a gas-film-type core for on-line plugging of a power plant boiler flue and a plugging method of the gas-film-type core. The gas-film-type core comprises a gas film, wherein a stop valve is arranged on an inflation port of the gas film; and a pressure gauge is arranged on the gas film. During plugging, a hoisting hole is formed in the rear part of a baffle door of the flue, then the gas-film-type core is placed in the flue and inflated, and the inflation port is plugged after the gas-film-type core is inflated to a specified pressure via the inflation port to realize on-line plugging of the flue; and during dismounting, pressure relief recovery is performed through the stop valve. On the one hand, the selected materials have the advantages of light weight, easiness in transportation, reusability, wear resistance, high temperature resistance, superior flame retardancy, quick self-extinguishing after leaving of open fire and the like; and on the other hand, compared with the prior art, the gas-film-type core demands fewer mounting personnel and less equipment from transport to installation, realizes non-stop and non-flue-in plugging, and not only guarantees the personnel security but also is convenient and quick, and the cost is lowered.

Description

technical field [0001] The invention relates to a plugging of a chimney flue of a power plant, in particular to an air-film type core body for online plugging of a boiler flue of a power plant and a plugging method thereof. Background technique [0002] Because the chimney of the power plant needs to be constructed and the production must be guaranteed, it is necessary to switch between the main chimney and the temporary chimney, close the baffle door between the temporary chimney and the main chimney, and the flue gas will be discharged from the temporary chimney. However, if the baffle door is not tightly sealed, the flue gas will leak to the main chimney, and it needs to be blocked so that no flue gas can pass through the main chimney. When the baffle door is not tightly sealed, the conventional solution is to reduce the load and then the operator enters the flue to seal it, and installs a smoke-blocking steel plate and a smoke-blocking brick wall. But there will be grea...
