Abstract
The utility model belongs to the technical field of thermal explosion pulse soot blowing, and particularly relates to a full-distributed thermal explosion pulse blower which mainly comprises at least two pulse blowing units. Each pulse blowing unit comprises a pulse generator, a distribution device or a distribution igniting device, and a special control device which is connected with the distribution device or the distribution igniting device through a control cable. The full-distributed thermal explosion pulse blower has major advantages in greatly increasing reliability of control systems and saving control cables.
Description
Technical field
The utility model belongs to the heat explosion pulse ash-blowing technical field, is specifically related to all-distribution type heat explosion pulse ash-blowing device.
Background technology
Heat exploding pulse sootblower is called for short pulse soot blower, have another name called the shock-wave ash blowing device, the shock wave soot blower, weak quick-fried soot blower, blast wave blower, the detonation wave soot blower, pinking pulse soot blower etc., invent by the people of the former Soviet Union the earliest, imported China in 1988 into, develop by " gas big gun ", its basic principle of blowing ash is: the gaseous mixture that makes fuel and oxidant gas with impulse generator that flue is communicated with in light a fire and explode, utilize " the alternation punching press is inhaled and drawn effect " of the compression shock ripple of blast generation, " the purging effect " of " physics effect of micro-explosion " and high-speed pulse jet blown down the various dust stratifications on boiler heating surface and the flue wall, has vibration simultaneously concurrently, three kinds of deashing effects of sound wave and high temperature pyrolysis.Impulse generator claims shock wave generator, surge generator, blast wave generator, detonation wave generator, blast jar, Impulsive tank etc. again; Impulse generator can directly be communicated with flue, also can be communicated with flue by pulse conduit, and pulse conduit claims transmitting tube, jet pipe etc. again.Because belonging to dry type blows ash, and blow that grey intensity height, no dead angle, sphere of action are big, good energy-conserving effect, equipment dependability height, to blow grey expense cheap, has impayable superiority with traditional steam soot blowing ratio, not only be used for heated surface at the end of boiler at large and replaced traditional steam soot blowing, and begin to be used to blow down industrial furnace interior dust stratification and slagging scorification, even also attempted being used for other occasions such as auxiliary deashing of electrostatic precipitator.
Heat exploding pulse sootblower can be divided into five big parts: impulse generator, air distributing device or distribution igniter, feeder, control system and pipe-line system.Because next boiler of most applications needs some impulse generators, so a cover heat exploding pulse sootblower comprises a plurality of impulse generator groups mostly, each impulse generator group comprises an impulse generator at least.For distribution type heat explosion pulse ash-blowing device, each impulse generator group all is equipped with exclusive air distributing device or distribution igniter, and such impulse generator group and the air distributing device that is disposed thereof or distribution igniter just are called as an impulse soot blowing unit usually.
The control system of existing heat exploding pulse sootblower adopts centralized control bar none, even host computer is arranged, also be earlier by switch board in the middle of the PC control, go to control each air distributing device or distribution igniter by middle switch board again, this control mode once middle switch board break down, often cause a whole set of soot blower all to be difficult to operate as normal, its reliability is lower.
The utility model content
The purpose of this utility model is: all-distribution type heat explosion pulse ash-blowing device is provided, and its reliability is higher.
Scheme of the present utility model is: all-distribution type heat explosion pulse ash-blowing device, mainly comprise at least two impulse soot blowing unit, each impulse soot blowing unit all includes impulse generator, air distributing device or distribution igniter and exclusive control device, and this exclusive control device is connected with air distributing device or distribution igniter by the control cable.
Because each impulse soot blowing unit all disposes exclusive control device, also can not influence the control device operate as normal that other blows grey unit even the control device of certain impulse soot blowing unit breaks down, thereby have higher reliability.
In order to improve automaticity, described all-distribution type heat explosion pulse ash-blowing device can also comprise host computer, host computer is connected by the control device of control line with each impulse soot blowing unit, host computer can be a PC, it also can be Programmable Logic Controller, can also be single-chip microcomputer, host computer can also dispose touching display screen.
Described exclusive control device can comprise Programmable Logic Controller, also can include single-chip microcomputer.
Major advantage of the present utility model is:
1. the control device of certain impulse soot blowing unit breaks down, and does not influence the operate as normal of other impulse soot blowing unit;
2. more and when adopting bus mastering mode when the quantity of impulse soot blowing unit, can save a large amount of control cables.
