3. beneficial effect
Compared to prior art, the invention has the advantages that:
(1) adopt the coal gasification wastewater pipe line cleaning device of this patent, structure is simple, directly can reconstruct, directly install device of the present utility model additional at pipeline two ends to be cleaned to existing sewer line, with low cost, is suitable for promoting.
(2) the coal gasification wastewater pipe line cleaning device of this patent, a cleaning can reach the effect same often processed in two ways, has the effect of high pressure water cleaning and Chemical cleaning simultaneously; According to cleaning experience in the past, adopt high pressure water cleaning 1000m sewer line that is long, diameter DN250 to need one-month period, required cost is more than tens0000 yuan; And adopt the device of this patent to clean this pipeline, with the wiper speed of service for 0.7m/s, the time completing a complete cleaning process is no more than 1 hour, and required cost is lower than 2000 yuan.Tube cleaning arrangement of the present utility model significantly can improve cleaning efficiency, saves cleaning cost.
Accompanying drawing explanation
Structural representation when Fig. 1 is the use of coal gasification wastewater pipe line cleaning device.
Detailed description of the invention
Below in conjunction with Figure of description and specific embodiment, the present invention is described in detail.
embodiment 1
The coal gasification wastewater pipe line cleaning device of the present embodiment, comprise wiper 2, also comprise cell site 1, receiving station 6, first triple valve 5 and the second triple valve 9, cell site 1 is provided with cell site's inlet pipe 3, cell site's blow-down pipe 4 and cell site's turned letter line 13, receiving station 6 is provided with receiving station's inlet pipe 7, receiving station's blow-down pipe 8 and receiving station's turned letter line 14, cell site 1 is connected with the first triple valve 5, receiving station 6 is connected with the second triple valve 9, at cell site's inlet pipe 3, cell site's blow-down pipe 4, cell site's turned letter line 13, receiving station's inlet pipe 7, receiving station's blow-down pipe 8 and receiving station turn on line 14, be respectively arranged with valve, by the opening and closing of Valve controlling pipeline.
Structural representation when Fig. 1 is the use of coal gasification wastewater pipe line cleaning device, as shown in Figure 1, general sewer line, comprises grey water pot 10, and grey water pot 10 connects sewer line and cesspool 12 by pump 11.When needing cleaning sullage pipeline, the first triple valve 5, second triple valve 9 being connected to pipeline two ends to be cleaned, is namely sewer line to be cleaned between the first triple valve 5, second triple valve 9.
The operation principle of the present embodiment is specific as follows:
Under normal operating conditions, buck in ash water pot 10 is transported to cesspool 12 through pump 11, first triple valve 5, second triple valve 9 successively, wiper 2 is positioned at cell site 1, valve on cell site's inlet pipe 3, cell site's blow-down pipe 4, cell site's turned letter line 13, receiving station's inlet pipe 7, receiving station's blow-down pipe 8 and receiving station's turned letter line 14 is closed condition, be as the criterion with Fig. 1 state, now the first triple valve 5, second triple valve 9 is bypass state, and cell site's turned letter line 13, receiving station's turned letter line 14 are connected to cesspool 12 after being communicated with the bypass of the second triple valve 9.
When pipeline to be cleaned needs to clean:
(1) pump 11 stops, and the first triple valve 5 becomes pass-through state, and cell site's inlet pipe 3 is connected, and rinse water enters cell site by cell site's inlet pipe 3, utilizes the hydraulic pressure of rinse water wiper 2 to be pushed to the second triple valve 9 position.
(2) second triple valves 9 become pass-through state, open receiving station's turned letter line 14, continue to utilize the hydraulic pressure of rinse water that wiper 2 is pushed to receiving station 6.
(3) now close cell site's inlet pipe 3 and receiving station's turned letter line 14, open receiving station's inlet pipe 7 and cell site's turned letter line 13, rinse water is entered by receiving station's inlet pipe 7, and wiper 2 is pushed back to cell site 1.
(4) close receiving station's inlet pipe 7, open cell site's blow-down pipe 4, receiving station's blow-down pipe 8 and receiving station's turned letter line 14, by the rinse water turned letter in cell site 1 and receiving station 6.
(5) first triple valve 5, second triple valves 9 all switch to bypass state, complete the cleaning of pipeline to be cleaned, now pipeline to be cleaned have passed through wiper 2 and rinse water back and forth each cleaning once, and sewage pump 11 can be opened, and reactivates sewer line.
