background

In the electrostatic precipitator, the negative and positive poles are the core part of the precipitator, it is direct relation to whether the precipitator can work normally, it is very important to do well the installation of negative and positive pole system, the negative pole line is the discharge electrode of electrostatic precipitator, not only must consider the inter-polar distance between the negative and positive poles when installing the negative pole line, and will notice good insulation between the negative and positive poles, there are many electrostatic precipitators when installing the negative pole line now, in order to make the insulation that can be fine between the negative and positive poles, connect the steel sheet with the negative pole line lower part usually, form a simple frame suspension in the electric field, do not carry out effectual fixed. This structure has the following disadvantages: 1. the polar line lower end frame is suspended in an electric field, when the dust remover operates, smoke sweeps a cathode line to cause the shaking of the cathode line, so that the distance between a cathode and an anode is changed, even discharge is generated due to the reduction of the distance between different poles in the moment, the normal work of the dust remover is influenced, and meanwhile, dust adsorbed on the cathode line is blown away ceaselessly due to the shaking of the cathode line, so that the dust removing efficiency is influenced; 2. simple negative pole frame works under the flue gas of high temperature, will cause the frame to warp, arouses that the negative and positive poles interval changes, can cause the electric field finally not normally to work. It is therefore necessary to redesign the electrostatic precipitator pole line bottom fixture.
