Problems in use of wet dust removal
Thread Content
I have designed, manufactured, and installed wet dust collectors for ten years (including horizontal and vertical venturis, water film, swirl plates, composite venturis, water baths, and impact types). If you have encountered various problems during the work process, you can discuss them together.
How to solve the problem of clogged water distributor, clogged pipes and corrosion?
The question is too vague. 1\ You said that the water distributor and pipes are clogged. Generally, there are only two possibilities. The circulating water is too dirty or the alkali content in the water is too high. Generally speaking, the PH value is greater than 9, which can easily lead to scaling. The simplest solution is to increase the nozzle gap and replace the nozzles within the scope allowed by the design. The adjustment of the water will be too much. 2\ Corrosion problem: I don’t know where the corrosion is, whether it is the pipe or the pipe. As for the dust collector body, different parts have different solutions. It is worth mentioning that many problems that appear to be corrosion are not necessarily caused by corrosion alone. The flue gas must also be analyzed to see whether the dust removal efficiency is insufficient, whether the dehydration is not clean, etc., because these problems cause the flue gas to have excessive impact wear on the dust collector and interact with corrosion.:handshake :handshake
Wet dust removal equipment mainly has the following problems: 1. Dehydration problem of flue gas (the outlet is saturated temperature) ； 2. Corrosion problem of fans 3. Secondary pollution problem of sewage 4. Smoke filtration problem
The problem of secondary pollution of sewage is troublesome!
It's great to meet an expert. I'm working on a flue gas cleaning project and one step involves using a venturi device. Our design uses a fixed throat and adjusts the water spray volume to adapt to load fluctuations. But the owner thinks that a venturi device with an adjustable throat is better. I am preparing a document to convince the owner. What is your opinion on the pros and cons of adjustable throat and fixed throat designs? It would be best to list the advantages and disadvantages of the two designs, thank you
I wonder if the poster has had experience with a power wave washing device? It integrates desulfurization and dust removal, is simple and convenient, and saves space. However, the problem of pressure drop is difficult to solve.
