Device for collecting dust in boiler heating surface pipe

Abstract

The invention provides a device for collecting dust in a boiler heating surface pipe. Dust and powder in a pipeline with ash to be removed is packaged into the collecting device, pollution to the working environment of production is avoided, and thus physical health of workers is guaranteed. The device for collecting dust in the boiler heating surface pipe comprises a barrel with an opening in the upper portion, and a bottom plate is arranged at the bottom of the barrel. The device for collecting dust in the boiler heating surface pipe is characterized in that an annular positioning plate is arranged on the inner annular face of the upper middle portion of the barrel with the opening in the upper portion, a multi-hole plate is supported by the upper end face of the annular positioning plate, the multi-hole plate, the barrel and the bottom plate form an inner cavity in an enclosed mode, the inner cavity is filled with water, a large center hole is formed in the center of the multi-hole plate, small through holes are evenly distributed in the annular face of the multi-hole plate, a sponge cover is installed on the upper end face of the multi-hole plate, a straight pipe penetrates through the large center hole from top to bottom and stretches below the water surface of the inner cavity, and the straight pipe is a hollow pipe.

Description

technical field [0001] The invention relates to the technical field of dust collection structures in boilers, in particular to a dust collection device in tubes on heating surfaces of boilers. Background technique [0002] Among the components of general boilers, the superheater and economizer are composed of serpentine tubes, but when the serpentine tubes are processed, a lot of dust and dust will be generated inside the tubes. Because the superheater and economizer are important parts in the operation of the boiler, they need to be filled with water to operate as a whole. The accumulation of dust will affect the normal flow of water and steam, resulting in poor heat exchange. Therefore, dust and dust must be cleaned before the finished parts. The general cleaning method uses compressed air to directly blow soot from one end of the pipe to the other end, and the dust and dust are directly discharged from the other end of the pipe. The discharged dust and dust pollute the wo...

Because the superheater and economizer are important parts in the operation of the boiler, they need to be filled with water to operate as a whole. The accumulation of dust will affect the normal flow of water and steam, resulting in poor heat exchange. Therefore, dust and dust must be cleaned before the finished parts. The general cleaning method uses compressed air to directly blow soot from one end of the pipe to the other end, and the dust and dust are directly discharged from the other end of the pipe. The discharged dust and dust pollute the working environment of production, and cause damage to the body of the staff.
