Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in figure 1, the self-drainage device of the pressure-equalizing dust remover comprises a water filter valve 1 communicated with the lower end of an ash bucket 20 of the pressure-equalizing dust remover, wherein the water filter valve 1 is communicated with a middle ash bucket 4 through a short circuit 2 and a pneumatic ash discharge ball valve 3. One side of the short joint 2 is communicated with a water storage tank 10 through a drain pipe 7, a pneumatic water inlet valve 8 is arranged between the drain pipe 7 and the water storage tank 10, the bottom of the water storage tank 10 is communicated with a sewage discharge pipe 21, and a pneumatic water discharge valve 11 is arranged on the sewage discharge pipe 21. The upper part of the water storage tank 10 is communicated with the water outlet pipe 7 through a water pump 12 and a water outlet pipe 13. The bottom of the intermediate ash bucket 4 is provided with a humidifier 6, and the humidifier 6 is connected with the intermediate ash bucket 4 through an ash discharge valve 5. The ash discharging valve 5 is a star-shaped ash discharging valve. As shown in fig. 2, the water filter valve 1 includes a cartridge assembly 14, a valve plate 15 and a valve housing 16. The valve plate 15 and the valve shell 16 are detachably connected through a screw rod, a round hole is formed in the middle of the valve plate 15, and the filter element assembly 14 is installed at the round hole. As shown in fig. 3 and 4, the filter element assembly 14 includes a filter element housing 17 and a stainless steel sintered mesh 18, the stainless steel sintered mesh 18 is fixedly connected with the filter element housing 17, a sealing gasket 19 is arranged between the filter element housing 17 and the valve plate 15, and the sealing between the filter element assembly 14 and the valve plate 15 is sealed by the sealing gasket 19. A liquid level meter 9 is arranged in the water storage tank 10.
The utility model discloses a theory of operation:
when the ash bucket 20 of the pressure-equalizing dust remover does not need to discharge ash at ordinary times, the valve plate 15 of the water filter valve 1 is in a closed state. At the moment, the filter element assembly 14 of the water filtering valve 1 plays a role in filtering water, and the water is filtered into the drain pipe 7 through the stainless steel sintering net 18 in the filter element assembly 14 and enters the water storage tank 10 through the pneumatic water inlet valve 8.
The barrel of the water storage tank 10 is provided with a liquid level meter 9 which has the functions of remote transmission and interlocking. The liquid level meter 9 is interlocked with the pneumatic drain valve 11. When the water level in the water storage tank 10 reaches the highest position, the pneumatic drain valve 11 is opened to drain accumulated water into the drain pipe 21. When the water level in the water storage tank 10 is reduced to 300mm above the opening of the water pump 12, the water is stopped to be drained.
When the ash bucket 20 of the pressure-equalizing dust remover needs to discharge ash, the water filtering valve 1 is opened, the valve plate 15 is in a pumping state, and semi-dry ash enters the middle ash bucket 4. The humidifier 6 and the ash discharging valve 5 are sequentially opened to start ash discharging operation, and the water filtering valve 1, the ash discharging valve 5 and the humidifier 6 are sequentially closed to finish the ash discharging operation after the ash accumulated in the ash hopper 20 of the pressure-equalizing dust remover is discharged.
The utility model discloses a water strainer valve 1 can also realize the anti-cleaning function of online. The filter element assembly 14 inside the water filter valve 1 may be clogged during a long-term water filtering process. After the ash bucket 20 of the pressure-equalizing dust remover is emptied, the pneumatic ash discharging ball valve 3 is closed, the water pump 12 is started to spray clean water at the upper part of the water storage tank 10 into the short connector 2, the water filtering valve 1 is reversely cleaned upwards, and dirt on the filter element assembly 14 can be washed clean.
The in-line backwash function ensures that the filter element assembly 14 is used for a long period of time without clogging. However, when the filter element assembly 14 needs to be replaced due to corrosion or the like, the filter element assembly 14 may be replaced when the filter valve 1 is opened to perform the dust discharging operation (when the valve plate 15 is in the drawn-out state). Specifically, the original filter element shell 17, the stainless steel sintering net 18 and the sealing gasket 19 are taken out, and the new filter element assembly 14 is put in, so that the operation is simple and convenient, and the replacement is quick.
The utility model discloses the operation is stable, the simple operation, and the maintenance is changed conveniently, should realize remote control and interlocking operation as required.
