Clamp for leakage stoppage of boiler economizer

Abstract

The invention discloses a clamp for leakage stoppage of a boiler economizer. The clamp comprises a lower pressing plate, a lower pressing groove is formed in the middle part of the top part of the lower pressing plate, and supporting plates are arranged at two ends of the top part of the lower pressing plate; and an upper pressing plate is arranged at the top part of the lower pressing plate, frame plates are arranged in the middle parts of two sides of the upper pressing plate, and an upper pressing groove is formed in the middle part of the bottom end of the upper pressing plate. According to the clamp, sealing grooves and rubber gaskets are arranged so that the advantages that leakage of a pipeline can be treated in a continuous furnace state, meanwhile, the tight contact with a leakagepart is improved, and normal production are guaranteed are achieved; the upper pressing groove and the lower pressing groove are arranged, so that the advantages that the pipeline is placed conveniently, and the leakage part of the pressure pipeline of the boiler is exposed due to device deviation are achieved; and the upper pressing plate is fixed to the lower pressing plate through bolts, so that the advantages that the tight contact between the sealing groove and the rubber gasket and the pipeline is increased, and the gap between the sealing groove and the rubber gasket and the connectingposition of the pipeline is reduced are achieved.

Description

technical field [0001] The invention relates to the technical field of metallurgical boiler systems, in particular to a clip used for plugging leakage of a boiler economizer. Background technique [0002] The economizer is a device installed in the tail flue of the boiler to recover waste heat. It is the heating surface that heats the boiler feed water to become saturated water under the drum pressure. Because it absorbs the heat of low-temperature flue gas, reduces the temperature of boiler exhaust gas and reduces the heat loss of exhaust gas, so it can save energy and improve the operating efficiency of the boiler. [0003] Existing boiler economizers are light-tube economizers, and the economizer pipes are arranged in a serpentine shape. The leakage of the weld seam at the header, if not dealt with in time, will lead to an expansion trend, and the furnace has to be shut down for treatment, which will affect the operation and production of the boiler.

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a clamp for leakage plugging of boiler economizer, capable of plugging the leakage of economizer with pressure under the condition of non-stop boiler, preventing its leakage tendency from expanding and ensuring production The continuous and stable advantages solve the problem that the existing boiler economizer is a bare-tube economizer, and the economizer pipes are arranged in a serpentine shape, with a large number and tight arrangement. Because the pipes are high-pressure water supply, the pipes are washed for a long time , it is easy to cause weld leakage at the header of the pipeline and the economizer. If it is not dealt with in time, it will cause an expansion trend, and the boiler has to be shut down for treatment, which will affect the operation and production of the boiler.
