A horizontal wet electric high-efficiency discharge electrode and its frame structure

Abstract

The invention relates to a horizontal hygroelectricity efficient discharge electrode which comprises two semi-circular pipes. The two semi-circular pipes form a discharge electrode through touch welding spots. The semi-circular pipes are provided with staggered discharge tip ends. Each discharge tip end is provided with four long and thin discharge points distributed in a staggered mode. The discharge tip ends point to dust collecting poles at the two sides respectively. The frame structure of the discharge electrode comprises a small edge-fold type framework, a suspending rod, a large framework, a framework limiting device, a first supporting steel channel and a second supporting steel channel. The discharge electrode has the advantages of being high in reliability, good in airtightness and resistant to corrosion; discharge performance of the discharge tip ends is improved, and efficient discharge is achieved; the discharge electrode is arranged flexibly according to density, and the utilization rate of an electric field is increased; possibility of short circuits is effectively avoided, and operation safety of hygroelectricity is improved; the limiting device is flexible and convenient to install, and therefore installing deviation is reduced; maintenance convenience of the efficient discharge electrode and the frame structure therefore is high; the efficient discharge electrode and a frame thereof are safe, stable and good in integrity.

Description

technical field [0001] The patent of the present invention relates to the field of environmental protection equipment for coal-fired boilers, in particular to a discharge electrode device for a horizontal wet electrostatic precipitator. Background technique [0002] In the environmental protection facilities of coal-fired boilers, in order to further reduce the dust content in the exhaust gas of the chimney and achieve emission standards, a horizontal wet power plant can be installed downstream of the desulfurization system. As one of the core components of horizontal wet electricity, the discharge electrode has an important impact on the performance and safe and stable operation of the wet electricity. However, in the humid and harsh electric field environment inside the wet electricity, there are often weak discharge capabilities of the discharge electrode and shortened life. On the other hand, the installation accuracy of the discharge electrode is required to be high, an...

As one of the core components of horizontal wet electricity, the discharge electrode has an important impact on the performance and safe and stable operation of the wet electricity. However, in the humid and harsh electric field environment inside the wet electricity, there are often weak discharge capabilities of the discharge electrode and shortened life. situation; on the other hand, the installation accuracy of the discharge electrode is required to be high, and due to the limitation of the discharge electrode and its frame structure during the installation process, problems such as large installation deviations often occur, and the discharge electrode is prone to deformation or even short circuit; moreover, the discharge electrode There are many components in the electrode, the production process is complicated, and the discharge tip is in the form of welding, which is easy to fall off during operation, which affects the discharge effect
