Pulse soot blower utilizing Venturi to premix air and acetylene

Abstract

The invention discloses a pulse soot blower utilizing a venturi to premix air and acetylene. The pulse soot blower utilizing the venturi to premix the air and the acetylene comprises an air cylinder,an acetylene gas cylinder, valves, flow meters, connection pipes, the venturi and a soot blowing tank. The venturi comprises an inlet section, a gradual shrinkage section, a throat section, a gradualexpansion section, an outlet section and injection hole. The soot blowing tank comprises a gas intake valve, a combustion chamber, an igniter, a jet section and end covers. The jet section of the sootblowing tank comprises a magnet block, a magnet hole and a connection shaft. The air and the acetylene gas are fully mixed through the venturi and enter the soot blowing tank to be combusted and exploded, generated high-temperature high-pressure smoke pushes the right end cover of the soot blowing tank to be opened and rushes to the soot blowing portion, and the soot blowing effect is achieved. By adjusting the valve of the gas cylinders to be at different opening degrees, the flows of the acetylene and the air can be adjusted, so that the mixing ratio of the gases is changed. The pulse sootblower utilizing the venturi to premix the air and the acetylene can achieve full mixing of the air and the acetylene gas according to the ratio; and the end cover at the outlet of the soot blowing tank cooperates with the magnet to achieve seal of the soot blowing tank in the gas conveying stage before ignition.

Description

technical field [0001] The invention relates to the field of gas premixed combustion, in particular to a pulse soot blower utilizing Venturi premixed air and acetylene. Background technique [0002] Gas pulse soot blower is a new generation of advanced soot blowing technology with excellent effect, reliable operation and simple operation and maintenance. It uses acetylene and other common combustible gases and air to mix and burn soot in a certain proportion. Different from the conventional combustion process, the rapid combustion and explosion of the mixed gas in the gas pulse sootblower can generate high-temperature and high-pressure flue gas. Ash falls off. [0003] The Venturi tube has a simple structure, low manufacturing and maintenance costs, and has been widely used in various fields such as production and life, such as flow measurement, gas mixing, and liquid impurity removal. The pulse sootblower needs to realize the premixing of acetylene and air before combusti...

AI Technical Summary

Problems solved by technology

The pulse sootblower needs to realize the premixing of acetylene and air before combustion and explosion. The traditional gas pulse sootblower sends the two gases into the mixer separately and then mixes them. The mixing effect is not good and the device is complicated.
