Abstract
A large four joint reversing valve with four cavities is a reversing device which is a centralized commutating design for a high regenerative temperature air combustion system of an industrial furnace and a gas and smoke system. The valve uses a vertical type biserial arrangement and provides four channels and uses hydraulic or gas drive. The upper channel is an air or gas inlet, and the lower channel is a smoke outlet, and the two middle channels are connected to a regenerator. A valve flap and a valve seat uses plane seal, and the valve seat is lined with a specially flexible seal material. The two groups of right and left valve flaps are driven to move via a driving connecting rod of a hydraulic cylinder, and the screw on the connecting rod and the driving rod can be adjusted to realize simultaneously reliable seal. Two driving air cylinders supply the oil in turn, and the device makes the force and the motion velocity of the two side the same.
Description
The utility model relates to a kind of novel combustion technology, and promptly heat accumulating type high temperature air combustion technology (HTAC) relates in particular to the large-scale four chamber four-way change-over valves of the crucial reversing arrangement of a kind of heat accumulating type high temperature air combustion technology.
HTAC is to settle combustor nozzle in oven in pairs, adopt heat-storage type fume residual heat recovering device, alternately switch air and the flue gas heat retainer (honeycomb ceramic heat accumulator or ceramic bead) that makes it to flow through, can reclaim the sensible heat of high-temperature flue gas to the full extent; Feed combustion gas (fuel oil) and air in the stove and penetrate at a high speed from the burner of particular design and entrainment on every side that flue gas forms the burning of oxygen deprivation state, NOx is generated greatly reduce, since regenerative combustion technology fuel saving significantly, CO
2Discharge amount reduces significantly, has combustion flame simultaneously and elongates advantages such as uniform distribution of temperature field.
Large-scale four chamber four-way change-over valves are the crucial special-purpose reversing arrangements that alternately switch air and flue gas realization HTAC.Can be widely used on industry industrial furnaces such as iron and steel, machinery, coloured, petrochemical industry, building materials, boiler and waste incineration or the heating plant.
Large-scale four chamber four-way change-over valve devices and technology (number of patent application) are to be the reversing arrangement of industrial furnace heat accumulating type high-temperature air burning system air, coal gas and fume centralized commutation development and design specially.Four-way valve body (1) is divided into four chambers, and it is air or gas entry that there is upper channel (2) in upper chamber, and the middle part is divided into two chambers, and the left and right sides flap (6) and the left and right sides valve seat (7) that have the parallel longitudinal biserial to arrange adopt hydraulic pressure or air pressure to drive.Two Room about intermediate cavity has dividing plate to be divided into, left and right sides flap (6) are by left and right sides connecting rod (20), left and right sides driveshaft (9) link to each other and parallel passing about hold about upper chamber of portion and connecting rod (8) and be connected.Left and right sides flap (6) adopts the plane to compress sealing with valve seat (7), studs with corrosion-resistant extraordinary flexible sealing material on the valve seat (7), has certain sealing compensation function.Lower Disc on every group (6) adopts flexible connecting structure, and sealing is reliable.Middle part right chamber passage (4) and left chamber's passage (5) communicate with the regenerator on both sides respectively, and it is smoke outlet that lower chambers has lower passage (3).About two groups of valves drive synchronization motion simultaneously by connecting rod (8) by oil hydraulic cylinder (or cylinder) (18), diagonal angle two sealing surfaces can reach the while reliable sealing by the screw thread of adjusting on connecting rod (20) and the driveshaft (9).Connected by connecting rod (20) between lower Disc on two groups (6), left and right sides driveshaft (9) is by being placed in left and right sides setting sleeve (10) on the left and right sides valve seat (7) and accurately locating and leading.Two driving oil cylinder (or cylinder) (18) are once moved and are only used wherein one, and two cylinder alternating movements can make both sides active force and movement speed identical like this.
Hydraulic system (seeing accompanying drawing 2) adopts double pump system, and one of a use is standby.Two oil pumps (11) outlets connects one-way valve (12), and when guaranteeing a pump work, pressure oil can not enter another and flow back to fuel tank (19).To solenoid valve (16), the switching through solenoid valve (16) makes two oil cylinders (18) alternating movement to pressure oil after relief valve (13) is set up system works pressure.Hydraulic lock of being made up of two Pilot operated check valves (15) between solenoid valve (16) and the oil cylinder (18) (15) and two one-way throttle valves (14) connect, two one-way throttle valves (14) can be regulated the motion speed of two oil cylinders (18) respectively, hydraulic lock (15) is after commutation finishes solenoid valve (16) outage, fluid can not reflux in the oil cylinder (18), guarantees that four-way valve keeps original position in a period of time.
Be equipped with three on the four-way change-over valve near switch (17), divide three positions, upper, middle and lower to install, the neutral position is selector valve interfix effect, uses for baker.Two are used when commutation up and down.
When selector valve commutates requires to realize by electric control system according to combustion system, can control by the time, also can control by temperature.
