Tubular pile boiler steam system

Abstract

The invention relates to the technical field of constructional engineering equipment, in particular to a tubular pile boiler steam system. According to the technical scheme, the tubular pile boiler steam system comprises a boiler, a gas pipeline, an air pipeline, a steam pipeline, a water tank and two water inlet pipes, one side of the boiler communicates with a communicating pipe, the gas pipeline and the air pipeline both communicate with the communicating pipe, the boiler communicates with a smoke exhaust pipe, the communicating pipe is sleeved with a heat conduction pipe, and the end, awayfrom the boiler, of the heat conduction pipe communicates with the smoke exhaust pipe; and a wind shielding assembly is arranged in the heat conduction pipe, the end, close to the boiler, of the heatconduction pipe communicates with a waste gas pipe, the waste gas pipe communicates with a tail gas treatment device, the tail gas treatment device comprises a spray tower, a bag-type dust remover, an air blower and an active liquid pool, the other water inlet pipe communicates with the spray tower, the outlet end of the waste gas pipe communicates with the spray tower, and the active liquid poolcommunicates with an exhaust pipe. The tubular pile boiler steam system has the advantage that boiler waste gas can be effectively treated while heat discharged from a chimney is recycled.

Description

technical field [0001] The invention relates to the technical field of construction engineering equipment, more specifically, it relates to a steam system for a pipe pile boiler. Background technique [0002] Prestressed concrete pipe piles can be divided into post-tensioned prestressed pipe piles and pretensioned prestressed pipe piles. When making prestressed pipe piles, first mix the well-proportioned concrete and put it into the pipe mold, then carry out mold closing, tensioning, and centrifugal molding, and then put it into the steam curing pool and add steam for normal pressure steam curing (temperature 60 -85°C, the total time is about 6 hours), after the atmospheric pressure steam curing is completed, the pipe mold is removed, and the pipe pile is pulled into the autoclave for high temperature and high pressure steam curing (temperature 175-185°C, pressure 1.0Mpa, The total time is about 10 hours), and the pipe piles are finished products after being steamed at high...

AI Technical Summary

Problems solved by technology

[0004] The deficiencies in the prior art are: after the fuel in the combustion chamber is burned, the tail gas is discharged through the chimney, but when the smoke is exhausted, it will carry a large amount of heat, and the heat will be discharged from the chimney. On the one hand, it causes heat resources On the other hand, the smoke contains harmful substances such as sulfur-containing substances and nitrogen-containing substances, and also contains solid particles. The boiler exhaust gas is directly discharged into the atmosphere, which will cause great pollution to the environment, so it needs to be improved
