Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of dust removal and purification devices, specifically relating to a cold bridge blocking structure for the housing of a dust removal device. Background Technology
[0002] Dust removal and purification devices are mostly used for industrial waste gas dust removal. The outer shell of the dust removal device is usually made of metal, and an independent purification chamber is set inside the shell. Some industrial waste gases are high-temperature, high-humidity dust-laden waste gases. The high-temperature, high-humidity dust-laden waste gases are discharged after dust removal and purification in the purification chamber. The walls of the purification chamber are usually also made of metal. If high-temperature water vapor encounters the low-temperature purification chamber wall, condensation will occur on the purification chamber wall, leading to secondary corrosion damage. Usually, a maintenance corridor is set outside the purification chamber wall. The low temperature of the outside will be conducted to the purification chamber wall through the metal structural components at the bottom of the maintenance corridor, causing local low temperatures in the purification chamber wall. High-temperature water vapor will condense at the low-temperature wall panels in the purification chamber, leading to secondary corrosion damage. Severe corrosion can cause perforation, reducing the performance of the dust removal device to the point where the purification chamber wall must be replaced. Replacing the purification chamber wall requires removing the outer shell, resulting in high maintenance costs and a short service life for the dust removal and purification device. Utility Model Content
[0003] The purpose of this utility model is to provide a cold bridge blocking structure for the housing of a dust removal device. By setting multiple cold bridge blocking structures between the housing and the wall of the purification chamber, the conduction of external low temperature to the purification chamber wall is blocked, ensuring that the purification chamber wall does not experience local low temperature, thus avoiding the risk of condensation and secondary corrosion on the purification chamber wall; it also eliminates the need to replace the purification chamber wall in a short period of time, thereby reducing maintenance work, lowering maintenance costs, and ensuring the service life of the dust removal and purification device.
[0004] This utility model is achieved through the following technical solution:

Multiple independent purification chambers 2 are provided inside the shell 1. One side of each purification chamber 2 is fitted against one side of the shell 1. A reinforced insulation layer is provided on the side of the purification chamber 2 that is fitted against the shell 1 to prevent heat transfer from the purification chamber 2 to the surface of the shell 1. The other side of the purification chamber 2 is spaced apart from the shell 1. An air inlet duct 3 and an exhaust duct 4 are provided between the two chambers, spaced vertically. Valves are installed between the air inlet duct 3, the exhaust duct 4 and the purification chamber 2.
