Embodiment Construction
[0021] A device for dealing with clogged ash in the electrostatic precipitator, the structure of which is as follows: figure 1 , figure 2 As shown, it includes a water filter 1, an air pipe 4, a nozzle 6 and an installation sleeve 5. Near the lower ash opening 8 on the four sides of the ash hopper walls 3 of the ash bin 2, there is a hole deviated from the axis of the ash hopper walls 3 respectively. A mounting sleeve 5 is welded on the hole, and a connecting flange 12 is arranged on the mounting sleeve 5 . The nozzle 6 is placed in the installation sleeve 5 , and the connection flange 12 at its rear end is fixedly connected with the connection flange 12 on the installation sleeve 5 . The air delivery pipe 4 surrounds the ash delivery bin 2 and is connected to the air inlet 10 at the rear end of the nozzle 6 , and a water filter 1 is connected to the air delivery pipe 4 .
[0022] The structure of the nozzle 6 is as image 3 , Figure 4 As shown, the outer diameter of th...

The invention relates to a method and a device for processing clogging of an electrostatic dust collection ash transporting cabin. The device comprises a mounting casing pipe fixed on the ash bucket wall of the ash transporting cabin, a nozzle fixedly connected with the mounting casing pipe, an air conveying pipe connected with the nozzle and a water filter mounted on the air conveying pipe, wherein compressed air without water is introduced into the ash transporting cabin through the nozzle to form jet flow to generate disturbance effects on the clogging of an ash discharging opening. According to the device and the method disclosed by the invention, the disturbance effects of the compressed air to fly ash are used for avoiding the problem of blocking the ash discharging opening by deposited dust on the ash discharging opening, so as to guarantee the normal operation of a dust collection system and get rid of the constraint of the conventional methods with great labor intensity and low efficiency, such as a manual beating method; and the device and the method have wide popularization and application values.
Description
technical field [0001] The invention relates to an electrostatic precipitator, in particular to an ash conveying bin in the electrostatic precipitator. Background technique [0002] Electrostatic precipitator is a kind of dust collection method that uses electrostatic field to ionize gas, and dust particles are charged and adsorbed to electrodes. It is used in metallurgy, chemical and other industries to purify gas or recover useful dust particles, as well as for factories that use coal as fuel. , Power station, collect coal ash and dust in flue gas. When the dusty gas passes through the high-voltage electrostatic field, the air molecules are ionized into positive ions and electrons, and the electrons combine with the dust particles in the process of running to the positive electrode, so that the dust particles are negatively charged and tend to discharge and deposit on the surface of the anode. [0003] The fly ash in the electric field ash delivery bin of the electrostati...
