6-ton coal-fired boiler desulfurization tower dust collector designer

Ton coal-fired boiler desulfurization tower dust collector design manufacturer The desulfurization tower can also perform the functions of desulfurization and dust removal, so it is also a desulfurization dust collector. The desulfurization dust collector must both desulfurize and remove dust. To be able to be applied industrially, wet treatment is generally used, so tower-type treatment is generally used, and other methods are rarely used. Therefore, in many cases, when it comes to desulfurization dust collectors, desulfurization towers are generally used. Desulfurization flue gas desulfurization is the process of removing sulfur and compounds in the flue gas, which mainly refers to the sulfur and compounds in the flue gas. to meet environmental requirements. Post-combustion desulfurization, also known as flue gas desulfurization (RN, for short), in technology, according to the type of desulfurizer, can be divided into the following five methods: (limestone)-based calcium method, based on magnesium method, N-based sodium method, N-based ammonia method, organic alkali-based organic alkali method. The most commonly used commercial technology in the world is the calcium method, accounting for more than %. According to the dry and wet state of the absorbent and desulfurization products during the desulfurization process, desulfurization technology can be divided into wet method, dry method and semi-dry (semi-wet) method. Wet technology uses a solution or slurry containing an absorbent to desulfurize and process desulfurization products in a wet state. This method has the advantages of fast desulfurization reaction speed, simple equipment, and high desulfurization efficiency. However, it is generally prone to severe corrosion, high operation and maintenance costs, and ease of use. Cause secondary pollution and other problems. The desulfurization absorption and product treatment of dry process technology are all carried out in a dry state. This method has the advantages of no sewage and waste acid discharge, low equipment corrosion, no obvious cooling of the flue gas during the purification process, high flue temperature after purification, and is conducive to chimney exhaust. It has the advantages of less gas diffusion and less secondary pollution, but it has problems such as low desulfurization efficiency, slow reaction speed, and bulky equipment. Semi-dry technology refers to the flue gas in which the desulfurizer is desulfurized in a dry state and regenerated in a wet state (such as the water-washed activated carbon regeneration process), or the flue gas is desulfurized in a wet state and the desulfurization product is processed in a dry state (such as spray drying). Desulfurization technology. In particular, the semi-dry method, which desulfurizes in a wet state and processes desulfurization products in a dry state, has the advantages of fast wet desulfurization reaction speed and high desulfurization efficiency, and the dry method has no sewage waste acid discharge and desulfurization products. It has attracted widespread attention due to its ease of handling. According to the use of desulfurization products, it can be divided into two types: discard method and recovery method, dry desulfurization and wet desulfurization, as well as double subtraction desulfurization and the old history of limestone powder desulfurization technology.
