Problems solved by technology

[0004] Combined with Figure 1, the traditional pulse soot blowing device usually uses multi-point shared mixed ignition, and uses electric valves or mechanical distributors to distribute mixed gas to the soot blowing point. There is a distribution header between the generators, and electric ball valves are used to distribute the mixed combustible gas. In this way, during the operation of the sootblower, the valve body of the electric valve must inevitably withstand the impact of pulsed high-temperature pulsed flames for a long time, and the internal gasket quickly Aging, even causing the ball valve core to break, the life and reliability of the valve body are greatly affected, and the failure rate is high

Embodiment Construction

[0021] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0022] Referring to Fig. 3, the composition of the unit split type gas pulse soot blowing device includes a gas source allocation unit 2, a gas distributor 3, a pulse initiator 5, a pulse generator 7 and an emission nozzle 9. The gas enters the gas source allocation unit through a pipeline 1, and each One emission nozzle is equipped with a pulse generator to form a soot blowing point, and every two soot blowing points are installed in a group where soot blowing is required in the boiler. The gas is connected to the initiators, and the gas is connected to the gas distributor through the gas pipeline after passing through the gas source adjustment unit. The initiators are connected, and the gas source adjustment unit is connected to the control device 10 through the cable 11 . A gas sensor 12 is arranged at the gas supply station, the pulse initiator, and the gas d...

Abstract

The invention relates to a unit fuel gas impulse ash blower, which comprises: a gas source distributor, a fuel gas distributor, an impulse initiator, an impulse generator, and an ejector, wherein each ejector has one impulse generator to form one ash blower; each 2-4 ash blowers are one group to be mounted on the position needing to blow ash inside the boiler; each ash blowing point via mixing gas tube is connected to one impulse initiator; the fuel gas via gas distributor is connected to the fuel gas tube and fuel gas distributor; the fuel gas distributor via tubes is connected to each impulse initiator; the air tube via gas distributor is connected to the impulse initiator; and the gas distributor is connected to the controller. The invention can avoid interference, prolong the service life, and improve the safety.

Description

(1) Technical field [0001] The invention relates to a boiler auxiliary equipment, in particular to a boiler soot blowing device. (2) Background technology [0002] As a revolutionary product of boiler soot blowing equipment, gas pulse soot blowing device has been recognized by boiler users in electric power and petrochemical industries for its efficient and intuitive soot blowing effect since its appearance in the 1990s. [0003] The working principle of the pulse soot blowing system is to fully mix a certain amount of combustible gas and air in the mixer according to a predetermined ratio, and then enter the pulse generator along the pipeline to form a high turbulent flow. Subsequently, the initiator ignites the combustible gas, and the flame is sent to the pulse generator at a very high speed along the mixed gas pipeline to ignite the turbulent combustible gas to form a deflagration. The pressure and temperature of the gas rise sharply in a very short time, and expand rapi...
