Spray head for gas pulse soot blower

Abstract

The invention discloses a nozzle for a gas pulse soot blower, which includes an output pipe, a nozzle, a deflector, a push rod and a control motor, one end of the output pipe communicates with the combustion chamber of the gas pulse soot blower, and the nozzle is arranged on the The other end of the output pipe is connected with the output pipe, the deflector is movably connected to the end face of the nozzle, one end of the push rod is movably connected to the deflector, and the other end of the push rod is set on the output shaft of the control motor. The rotation drives the push rod to expand and contract, so as to control the opening and closing angle of the deflector at the nozzle, and realize multi-angle and large-scale dust removal. Compared with the prior art, the present invention realizes the opening and closing of the deflector in the range of 0°-135° by rationally designing and optimizing the structure of the nozzle, changes the direction of the airflow injection, solves the problem of a single injection direction, and increases the The range of dust removal improves the flexibility of the nozzle, greatly reduces the input of manpower and material resources, and is economical; therefore, it has a very broad application prospect.

Description

technical field [0001] The invention relates to a nozzle, in particular to a nozzle for a gas pulse soot blower, and belongs to the technical field of boiler equipment. Background technique [0002] During the operation of coal-fired and oil-fired boilers, ash deposits generally occur on the heating surface at the rear, which increases the resistance of the flue gas and the temperature of the exhaust gas, which seriously affects the normal operation of the boiler. The steam soot blowing technology commonly used at home and abroad is not suitable for removing the soot accumulated at the tail of the boiler in many cases, and the ash removal effect is not ideal. The main reason is that steam soot blowing will increase the humidity of the flue gas, which is more likely to cause ash accumulation and blockage, and sometimes aggravate corrosion, especially for ash with high calcium or sulfur content. [0003] The gas pulse soot blower is a new generation of ash removal equipment w...
