The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Example 1:
as shown in fig. 1-3, a cleaning device for desulfurization and denitrification comprises a base 1, wherein a first upright column 2 is arranged on the base 1, the first upright column 2 is fixedly connected with a desulfurization tower 4 through a connecting frame 3, a water tank 5 is arranged at the bottom of the first upright column 2, cooling water 6 is filled in the water tank 5, a water pump 8 is arranged at the bottom of the water tank 5, a heating wire 7 is further arranged in the water tank 5, the water pump 8 is connected with a first annular sprinkler 12 at the top of the first upright column 2 through a water pipe 10, a first electromagnetic valve 11 is arranged between the water pump 8 and the first annular sprinkler 12, the first annular sprinkler 12 is arranged right above a shell, a water falling hole 120 is uniformly arranged on the first annular sprinkler 12, a second annular sprinkler 15 is arranged in the shell, and the second annular sprinkler 15 is connected with the water pipe 10, be provided with second solenoid valve 13 between water pump 8 and the second annular sprinkler 15, second annular sprinkler 15 is provided with the shower nozzle 16 towards shells inner wall top, still be provided with second stand 18 on the base 1, be provided with motor 20 on the second stand 18, motor 20 links to each other with output shaft 22, be provided with puddler 23 on the output shaft 22, the bottom of casing is provided with feed opening 24.
Specifically, because the uninterruptibility of thermal power plant's electricity generation has just also led to the flue gas production of continuous, needs sufficient desulfurizing tower 4 to clear up the flue gas, in order to reduce desulfurizing tower 4's clearance time, needs cool down desulfurizing tower 4 fast to carry out the washing operation.
More specifically, because desulfurizing tower 4 is because long-time and high temperature flue gas pipeline link to each other, desulfurizing tower 4 self inside temperature has also reached hundreds of degrees centigrade, can not directly carry out the water spray cleaning operation to desulfurizing tower 4 inside, can lead to a large amount of vapor production in the twinkling of an eye like this to produce the high pressure, can lead to desulfurizing tower 4 top cap to be washed away, the serious can take place to explode, cause casualties and loss of property.
In order to ensure the safety of the cleaning process, firstly, the cooling water 6 is sprayed outside the desulfurizing tower 4 for cooling, the water tank 5, the water pump 8, the water pipe 10 and the first electromagnetic valve 11 are used for sending the cooling water 6 to the first annular sprinkler 12, and the desulfurizing tower 4 is cooled from top to bottom through the water falling hole 120 on the first annular sprinkler 12.
More specifically, the desulfurizing tower 4 after cooling can utilize the rivers to wash the inner wall, combines water pipe 10 and second solenoid valve 13, sends water into the inside second annular sprinkler 15 of casing, clears up the sulphide on the desulfurizing tower 4 inner wall.
More specifically, since the high-temperature water, which is a high-temperature water having a temperature of fifty degrees centigrade or higher, has a good dissolving effect on the sulfides, the heating wire 7 is provided in the water tank 5, and after the cooling operation before completion, the cooling water 6 is heated by energizing the heating wire 7, so that the temperature thereof becomes high, and then the second electromagnetic valve 13 is combined to send the heated water to the second annular sprinkler 15, and the cleaning operation is started.
More specifically, 4 inner walls of desulfurizing tower may have some places that the adhesion layer is thicker, even high-temperature water also can't clear up the short time, carry out friction stir with the help of output shaft 22 and puddler 23 to the inner wall of desulfurizing tower 4, reach the clearance to the adhesion layer, cooperate the high-temperature water clearance, the effect is better.
Further, an annular air blower 25 is arranged on the feed opening 24, and an air outlet 21 is arranged at the top of the shell.
Specifically, the ring blower 25 may be used before cooling the outer wall of the desulfurization tower 4 to blow off the sulfide fumes inside the desulfurization tower 4 through the gas outlet 21.
Further, the material of the stirring rod 23 is plastic.
Further, the temperature of the cooling water 6 is maintained between fifteen and twenty degrees celsius.
Specifically, the temperature of the cooling water 6 should not be too low, which is likely to cause expansion with heat and contraction with cold, resulting in cracks in the desulfurizing tower 4.
Example 2:
this embodiment is a further improvement and a limitation of embodiment 1 on the basis of embodiment 1.
A cleaning apparatus for desulfurization and denitrification, comprising all the components of embodiment 1, further comprising:
further, a flow guide cover 17 is arranged at the bottom of the shell.
In particular, the advantage of the air guide sleeve 17 is that the warmed cooling water 6 can be collected for subsequent cleaning of the inner wall of the cooling tower.
Further, the output shaft 22 is uniformly provided with a mounting ring 220, and the stirring rod 23 is rotatably connected with the mounting ring 220.
Specifically, the arrangement of the mounting ring 220 facilitates the horizontal lifting of the stirring rod 23 by means of centrifugal force in the rotating process, increases the friction force with the inner wall of the desulfurizing tower 4, and improves the cleaning capacity.
Further, a waste water tank 26 is arranged at the bottom of the base 1.
Specifically, the waste water tank 265 is configured to collect waste water generated after the inside of the desulfurization tower 4 is cleaned.
The working principle of the embodiment of the invention is as follows:
as shown in FIGS. 1 to 3, a cleaning apparatus for desulfurization and denitrification is assembled as shown in the drawing.
And opening the first electromagnetic valve 11, sending the cooling water 6 in the water tank 5 to the first annular sprinkler 12, and cooling the outer wall of the desulfurizing tower 4 through the water falling hole 120.
The water flow is downward along the outer wall of the desulfurizing tower 4 and returns to the water tank 5 through the diversion cover 17, and the circulation is performed, after the temperature of the desulfurizing tower 4 is reduced, the first electromagnetic valve 11 is closed, the second electromagnetic valve 13 is opened, the heating wire 7 is switched on at the same time, the water in the water tank 5 is heated, and then the heated water reaches the inner wall of the desulfurizing tower 4 to be cleaned.
The second upright column 18, the motor 20, the output shaft 22 and the stirring rod 23 are arranged to scrape off the sulfide with a thick adhesive layer on the inner wall of the desulfurizing tower 4.
And cleaning for a period of time according to the operation, and then carrying out desulfurization and denitrification treatment on the desulfurization tower 4 again.
It should be noted that: the desulfurization tower is initially cooled through the first upright post, the water tank, the cooling water, the first annular sprinkler and the first electromagnetic valve, the high-temperature desulfurization tower in the later cleaning process is prevented from generating large amount of water vapor when encountering water, explosion is avoided, sulfide dust in the desulfurization tower is initially cleaned through the annular blower and the air outlet, the heated cooling water is continuously heated through the electric heating wire, the flow guide cover and the second electromagnetic valve, the interior of the desulfurization tower is cleaned through the second annular sprinkler, the sulfide cleaning effect of hot water is good, the sulfide with thick inner wall of the desulfurization tower is cleaned through the stirring rod, the motor and the second upright post, and the cleaning effect is improved.
