Description

Technical Field

[0001] The invention relates to the technical field of wet electrostatic precipitators, and in particular to an electrostatic precipitator weight and a preparation method thereof. Background Art

[0002] The wet electrostatic precipitator uses tens of thousands of volts of high voltage direct current to generate a strong electric field between the anode plate and the cathode wire, so that the electrons and ions in the gas carry the dust in the flue gas, and then move and attach to the anode plate and cathode wire through the electric field force. Subsequently, the flushing system is used to flush the anode plate and cathode wire, and the dust collected on their surface is flushed into the liquid collecting hopper and discharged to the sewage treatment station to achieve the purpose of purifying the flue gas.

[0003] However, as the medium and temperature inside the use environment are different, the weight of the cathode line of the wet electrostatic precipitator will be corroded and damaged due to the decrease in the pH value of the HCL gas inside the use environment, or the surface anti-corrosion will melt due to the excessively high inlet temperature of the wet electrostatic precipitator, causing its internal components to be corroded and damaged by the HCL gas, resulting in a short-circuit discharge between the positive plate and the cathode line of the wet electrostatic precipitator. When the weight of the wet electrostatic precipitator is in a high temperature and high HCL concentration environment for a long time, the weight of the wet electrostatic precipitator is particularly easy to be damaged. As a result, a short-circuit discharge occurs between the positive plate and the cathode line of the wet electrostatic precipitator, causing the wet electrostatic precipitator to fail to work normally.

[0004] Therefore, how to make the wet electrostatic precipitator hammer have both high temperature resistance and corrosion resistance has become an urgent problem to be solved in the current wet electrostatic precipitator device. Summary of the invention

[0005] In view of the above problems, the purpose of the present invention is to provide an electrostatic precipitator weight and a preparation method thereof, which can not only achieve effective thermal torsion, but also achieve the performance of a wet electrostatic precipitator weight that is both resistant to high temperature and resistant to corrosion by changing its weight structure, material and preparation process, while also greatly reducing the failure rate of the wet electrostatic precipitator and effectively improving production efficiency.

[0006] The technical solution adopted by the present invention is as follows:

[0007] The invention provides an electrostatic precipitator weight, which comprises a weight body. The weight body is in an arched structure and is made of epoxy resin material.

[0008] A method for preparing an electrostatic precipitator weight, the method comprising the following steps:

[0009] S1, making an arched open-type counter-mold;

[0010] S2, preparing epoxy vinyl resin and high temperature curing agent solvent in proportion;

[0011] S3. Pour the prepared epoxy vinyl resin solvent into the mold, wait for it to solidify and then demould it for use on the machine.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The invention significantly improves the performance of the equipment when used in a high-temperature, high-corrosion environment by changing the structure, material and preparation process of the heavy hammer, especially in the working conditions of high temperature and containing a large amount of HCL gas, its high temperature resistance and corrosion resistance are greatly improved, and the energy consumption during the operation of the equipment is effectively reduced. At the same time, it can effectively reduce the failure rate of the wet electrostatic precipitator and effectively improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a schematic diagram of the structure of an electrostatic precipitator weight proposed by the present invention;

[0015] Figure 2 It is a structural schematic diagram of the existing electrostatic precipitator weight.

[0016] Wherein, figure mark: 1-weight body. DETAILED DESCRIPTION

[0017] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0018] It should be noted that, in the description of the present invention, the terms "up", "down", "top", "bottom", "one side", "the other side", "left", "right", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not mean that the device or element must have a specific orientation, be constructed and operated in a specific orientation.

[0019] See attached Figure 1 The present invention provides an electrostatic precipitator weight, comprising a weight body 1, wherein the weight body 1 is an arched structure and is made of epoxy resin material.

[0020] like Figure 2As shown, most existing weight models adopt a conical structure. When the weight of this model is used on site, it is found that the exhaust gas passes through the wet electrostatic precipitator at a fast speed, which is not conducive to the electrostatic adsorption of the wet electrostatic precipitator when the current is low. At the same time, the bottom of the weight is conical and it is easy to hurt people after falling. The present invention can slow down the exhaust gas flow rate passing through the wet electrostatic precipitator, prolong the electrostatic adsorption time of the wet electrostatic precipitator under low current conditions, and optimize the bottom shape of the weight to reduce safety accidents during installation.

[0021] The existing wet electrostatic precipitator weight is generally made of lead-antimony alloy and the shell is made of corrosion-resistant plastic. However, from the actual use on site, the effect of this type of weight is not ideal. The damage rate of this type of wet electrostatic precipitator dust weight can reach about 65%. When the inlet temperature of the wet electrostatic precipitator reaches 75°C and the pH value of HCL inside the wet electrostatic precipitator reaches 2-3, the anti-corrosion layer of this weight will be melted, and the internal lead-antimony alloy will be corroded and damaged by HCL, causing a short-circuit discharge phenomenon between the positive plate and the cathode line of the wet electrostatic precipitator, causing the wet electrostatic precipitator to fail to work normally. The weight proposed by the present invention can be used stably for a long time in an environment of 80°C and the pH value of HCL is about 2.
