Description
Technical field
The present invention relates to a kind of flow-disturbing valve being applicable to control high-temperature flue gas Mars, belong to industrial gas emission device technique field.
Background technique
The high-temperature flue gas of boiler emission need meet national requirements for environmental protection, therefore, discharges after all needing at present to process high-temperature flue gas again.
The normal cyclone dust collector that coordinate process high-temperature flue gas at present, and controlled by valve body when high-temperature flue gas enters cyclone dust collector, traditional valve body exists flue-gas temperature high (300 ~ 900 DEG C), and high temperature modification valve body can be caused not open and fit badly.
Therefore, be necessary the flow-disturbing valve installing improvement when high-temperature flue gas enters cyclone dust collector additional, flow to problem to solve control high-temperature flue gas.
Summary of the invention
High temperature modification problem is there is for solving existing valve body; the invention provides a kind of flow-disturbing valve being applicable to control high-temperature flue gas Mars; solving when shutting down or produce time-out, colliding comparatively flanker when controlling the discharge of high-temperature flue gas and produce, ensureing upstream device sack cleaner safety.
The present invention is realized by following technical proposal: a kind of flow-disturbing valve being applicable to control high-temperature flue gas Mars, comprise flow-disturbing valve body and be arranged on the angle distance electric executor of flow-disturbing valve body outside, described flow-disturbing valve body arranges flow-disturbing valve turn, flow-disturbing valve is turned the first axle and the second axle that comprise parallel discharge, and is fixed on the valve plate of the first axle and the second axle both sides.
The cross section of described valve plate is rhombus.
Described first axle and the second axle are fixed on flow-disturbing valve body respectively by bearing support.
Described angle distance electric executor is flexibly connected with the front end of the first axle by double leval jib, third connecting rod successively.
Described first the tip of the axis is flexibly connected by first connecting rod, second connecting rod, the 5th connecting rod and the second axle successively.
Described angle distance electric executor is conventional Electric actuator, by each linkage mechanism and then drive the first axle and the second axle rotational valve plate.
Flow-disturbing valve provided by the invention is the flow-disturbing valve controlling flue gas as water curtain dedusting shunting device, when shutting down or produce time-out, third connecting rod is made by the driving of angle distance electric executor, double leval jib moves successively and then drives the valve plate be fixed on the first axle to close, and then drive the valve plate on the second axle also to close simultaneously, close flow-disturbing valve thus, blocking high-temperature flue gas flows to into cyclone dust collector, require to open by-pass valve simultaneously, safety valve, flue gas trend is followed successively by hot blast stove, air main, bypass blow-down pipe and the second screen collector, be discharged in air finally by the second blow-down pipe and go.This trend is referred to as wind and send by-pass line to move towards.Heat the heat smoke obtained through hot blast stove and enter into the second screen collector dedusting by air main and bypass blow-down pipe, the flue gas after dedusting is discharged in air by the second blow-down pipe and goes.In addition, when shutting down or produce time-out, the flue gas in dryer also enters into bypass blow-down pipe by air main, then dedusting in the second screen collector, and the flue gas after dedusting is discharged in air by the second blow-down pipe and goes.
The program can drop to the high-temperature flue gas in hot blast stove in safety range within the shortest time; guarantee the rear safety reliability of dry shutdown; also control sack cleaner import and export cigarette gas flow temperature simultaneously; guarantee sack cleaner is safe and reliable; can within the shortest time, the high-temperature flue gas in hot blast stove be dropped in safety range; dryer and hot blast stove are played a protective role; ensure to produce and normally carry out; make the three elements of dust explosion always keep oxygen content key element to control in guard wire, and lay down the interior pressure in system pipes in time.When flow-disturbing valve opened by needs, by program control angle distance electric executor, make third connecting rod, double leval jib moves the valve plate unlatching driving and be fixed on the first axle successively, and then drive the valve plate on the second axle also to open simultaneously.
The advantage that the present invention possesses and effect: flow-disturbing valve provided by the invention is arranged on into cyclone dust collector ingress; relating to part fine material flows to into cyclone dust collector with high-temperature flue gas; the isolated material of cyclone dust collector is as Product recycling; few part superfine-material is also had to be collected by secondary sack cleaner; waste gas is discharged through chimney, shuts down and produces flow-disturbing valve when suspending and just play important effect.Flow-disturbing valve arrangement stability provided by the invention is strong, equipment cost is low, apparatus adaptability is strong, fault in production is few, low cost of manufacture, economize on resources.The present invention changes the unlatching of conventional traditional manual control valve with closed, increases the unlatching of electro motion control valve with closed.In drying system, coordinate dust collector of water curtain to purify the waste gas containing dust, clean flue gas enters air through chimney, realizes emission of smoke tallies national requirements for environmental protection simultaneously.
