Abstract

The structure form and the working condition of the utility model are that: a top cover of an upper ash bin of a gas furnace is provided with an oil hydraulic cylinder and a valve shelf of the oil hydraulic cylinder, a cylinder piston rod is connected with a valve rod, and extends into the ash bin of the gas producer, and the valve rod is connected with a valve core. A lower ash bin is in flanged connection with the upper ash bin, and is internally provided with a partition with holes, and a seal ring is seated on the holes of the partition and is fixed by bolts. An ash bucket is in flanged connection with the ash bin, and forms an ash storage area with a lower part space of the partition of the lower ash bin, when the ash in the ash storage area is stored to a certain height, the device enables the valve core to move down to be seated on the seal ring under the action of the oil pressure according to an operational order, and then the device is in a closed and ash discharging state, at this time, an ash door cover of the ash bucket is opened to discharge the ash under the control of the operational order, after finishing discharging ash, the ash door cover is closed, and the valve core is lifted up, so that the device is in an open and ash storage state. Under the condition that the gas is normally made, the ash on the ash pan of the gas producer is slowly discharged into the ash bin under the action of a fire bar machine, and is dropped in the ash bucket, ans during the process, the gas producer continuously makes gas.

Description

A kind of not blowing out of immovable bed intermittent coal gas producer hydraulic pressure ash-discharging device

One, technical field:

The utility model relates to the ash exhauster that a kind of producer gas generator unloads not blowing out of ash.

Two, background technology:

Equipment current, produce unstripped gas with coal in middle or small chemical fertilizer of China and chemical enterprise mostly adopts immovable bed intermittent coal gas producer, the working method that this type of furnace is traditional is that operation must blowing out be unloaded ash once in 2-3 hour, divide the quality time of planting and whenever unload once the grey 3-5 that not only will account for, face and furnace temperature is fluctuated widely, cause the decline of gas furnace gas production rate, feed coal consumption to increase, the production cost of unit product is increased.

The utility model is the optimal selection that overcomes above-mentioned defective, and this technology is applicable to that not only new stove is supporting, and also can transform enforcement on existing old stove.

Three, utility model content:

The utility model is implemented in conjunction with intending the supporting simple stationary gas producer type of furnace.Consist of the following components: 1, oil hydraulic system: it comprises oil cylinder, piston and piston rod, vavle shelf (also being cylinder bracket) and is connected and fixed part etc.2, tightness system: it comprises valve rod, spool, sealing-ring, dividing plate and is connected and fixed part etc.3, storage ash system: it comprises Hui Cang on the gas furnace, following grey storehouse, ash bucket, grey door closure and drive disk assembly thereof etc.4, safety and ash flushing device: promptly on last grey storehouse, weld the adapter mouth of a DN25, connect with steam and secondary water system respectively, and by-pass valve control is set.Not blowing out hydraulic pressure ash-discharging device is made up of oil cylinder (1), piston and piston rod (3), vavle shelf (2), valve rod (7), spool (8), sealing-ring (10), dividing plate (9) etc., and its structure formation is:

This device is fixed on the producer gas generator both sides on grey storehouse (6), and its oil cylinder (1) seat is on vavle shelf (2), and piston rod (3) is connected with socket on pin (4) and the valve rod (7), and valve rod (7) lower end is connected with spool (8); Under producer gas generator, be provided with dividing plate (9) in grey storehouse (11), perforate on the dividing plate, and with sealing-ring (10) seat on the hole, fixed with bolt.Its effect is to open steam valve when ash bucket unloads ash, makes in the grey storehouse and to form steam curtain, to guarantee to unload grey safety.The effect of penstock is before spool is down shifted to sealing-ring, opens the valve water and washes down residual ash on the sealing-ring contact surface, to guarantee sealing effectiveness.Steam valve and penstock only when ash bucket unloads ash just by manually operating, be in closing condition when normally making gas.

Four, description of drawings:

Not blowing out of Fig. 1 hydraulic pressure ash-discharging device-store grey state (spool unlatching)

Not blowing out of Fig. 2 hydraulic pressure ash-discharging device-unload grey state (spool is closed)

Five, embodiment:

On grey storehouse 6 on the producer gas generator both sides, respectively be provided with one and overlap not blowing out hydraulic pressure ash-discharging device, its constructional feature is that the valve rod 7, the spool 8 that utilize the reactive force of oil pressure to drive this device are opened (on carry) or closed (moving down), and constitutes the same control effect of similar base-plate valves mutually with sealing-ring 10 on grey storehouse 11 internal partitions 9 down.Concrete implementation method is: vavle shelf 2 (also for cylinder bracket) is to be bolted on the producer gas generator on 6 top covers of grey storehouse, oil cylinder 1 and vavle shelf 2 are connected with flange, oil cylinder piston bar 3 is connected with pin 4 with valve rod 7 upper end sockets, and valve rod 7 lower ends put in the coal gas ashes storehouse with spool 8 and are connected with silk braid.Down grey storehouse 11 is connected for flange with last grey storehouse 6, in establish 10 on perforate dividing plate 9, sealing-ring in the dividing plate perforate, and with bolting.Ash bucket 14 also is connected for flange with following grey storehouse 11, and constitutes the storage gray area with following the lower partition space, grey storehouse.When storage gray area lime-ash was stored up certain altitude, this device made spool 8 move down and be located on the sealing-ring 10 according to operational order under the effect of oil pressure, and device promptly is in closing condition, is isolated from each other in storage gray area and the gas furnace.The grey door closure 15 of ash bucket 14 is opened under the control of operational order and is unloaded ash at this moment, unloads and closes ash bucket ash door closure 15 after ash finishes, and mentions ash-discharging device spool 8, makes in the gas furnace to communicate with storing gray area, and device is in the grey state of storage of opening.Normally making under the gas situation, the lime-ash on the gas furnace ash-pan 12 slowly enters grey storehouse and falls in the ash bucket by following grey storehouse 11 and sealing-ring 10 under the effect of grate mechanism and ash plough.Because the spool 8 of this device is in closed state with sealing-ring 10 when unloading ash, make gas continuously and do not interrupt so unload in the grey process gas furnace, thereby make coal gas system produce the continous-stable safe operation whole row, realized the energy-saving effect of high yield and low cost.

The utility model has the advantages that reasonable in design, simple in structure, open and close flexibly, operate steadily, safe and reliable, easy to operate, remarkable benefit, be that simple stationary gas producer realizes automatically adding Jiao, automatic ash-discharging, the continuous essential condition of gas processed and high yield and low cost.
