Vertical boiler exhaust noise elimination device

Abstract

A vertical boiler exhaust silencer, comprising a silencer, a left support leg, a right support leg, an intake pipe, a silencer pipe, an inner silencer, an outer silencer, a vent pipe, a soundproof chamber, and an exhaust pipe. The bottom end of the cylinder is supported by the left support leg and the right support leg; the air intake pipe is installed in the middle of the bottom end of the silencer cylinder, and the air intake pipe is connected to the internal silencer pipe of the silencer cylinder. The chamber is installed inside the outer anechoic chamber, the outer anechoic chamber is installed at the lower end of the anechoic cylinder, the upper end of the anechoic cylinder is equipped with a sound-resistance chamber, and the top of the external anechoic chamber is connected to the bottom end of the anechoic chamber through three ventilation pipes; An air outlet pipe is installed at the top of the sound chamber; an exhaust pipe is installed at the lower end of the right side of the muffler, and a drainage pipe is installed at the bottom right of the outer muffler chamber, and the other end of the drainpipe passes through the bottom of the muffler. The invention has large noise reduction capacity and good noise reduction effect, and can meet the requirements of relevant national standards.

Description

technical field [0001] The invention relates to a muffler for thermal power generation, in particular to an exhaust muffler for a vertical boiler. Background technique [0002] At present, boilers used in fields such as electric power, petroleum, chemical industry, metallurgy, and textiles often use steam discharge to achieve effective noise reduction. Since the exhaust steam of various boilers is not only high temperature and high pressure, but also has a wide frequency range, it is difficult to achieve the noise reduction effect achieved by only exhausting steam to meet the requirements of the "Noise Standards for Industrial Enterprises". Contents of the invention [0003] The purpose of the present invention is to provide a vertical boiler exhaust silencer, It has a large amount of noise reduction and good noise reduction effect, can meet the requirements of relevant national standards, has the advantages of compact structure, easy processing and production, etc....
