High temperature oil and dust containing combustible gas dust remover preheating device and preheating process thereof

Abstract

The invention relates to a high temperature oil and dust containing combustible gas dust remover preheating device and a preheating process thereof, and belongs to the technical field of gas dust removing. The high temperature oil and dust containing combustible gas dust remover preheating device particularly comprises a smoke chamber of a hot-air stove. The smoke chamber of the hot-air stove is connected with a replacement medium intake pipe. The smoke and gas outlet of the hot-air stove is connected with a first circulation pipe. The first circulation pipe is connected with a dust-containinggas inlet pipe. A third cut-off valve is installed on the first circulation pipe. An air intake of a circulation fan is connected with a second circulation pipe. The second circulation pipe is connected with a clean air outlet pipe. A fourth cut-off valve is installed on the second circulation pipe. An air outtake of the circulation fan is connected with the smoke chamber of the hot-air stove through a third circulation pipe. A fifth cut-off valve is installed on the third circulation pipe. The first circulation pipe is also connected with a first discharge pipe. A first discharge valve is installed on the first discharge pipe. The third circulation pipe is also connected with a second discharge valve. A second discharge valve is installed on the second discharge pipe. According to the high temperature oil and dust containing combustible gas dust remover preheating device and the preheating process thereof, the service life of the dust remover can be effectively prolonged, and the efficiency of dust removing efficiency is improved.

Description

Technical field [0001] The invention relates to a preheating device and a preheating process of a high-temperature oil-containing dust-containing combustible gas dust remover, and belongs to the technical field of gas dust removal. Background technique [0002] The characteristics of my country's resource endowment are "more coal, lean oil, and less gas." my country's oil and natural gas resources are relatively short, while coal reserves are relatively abundant. Therefore, coal will remain my country's most important primary energy source for a long time to come. Therefore, it is an inevitable choice for the development of my country's energy industry to develop coal grading, quality, and cascade utilization technology to realize the "high-quality and high-use, low-quality and low-use" coal energy.

AI Technical Summary

Problems solved by technology

This method has the following problems: 1. The low-temperature gas in the dust collector is discharged by feeding high-temperature gas. First, the equipment heats up sharply, causing thermal expansion and cold contraction to occur sharply, causing destructive consequences to the equipment. Second, the air in the dust collector is not replaced. As soon as the high temperature gas is introduced, it will cause the filter element, especially the metal filter element, to oxidize, which will affect the service effect and life of the filter element; 2. The oxygen content is not controlled during the heating stage, and it is replaced to the oxygen content until the final replacement stage

Since the temperature rise rate needs to be controlled during the preheating and heating stage, the preheating process is a long stage, which takes at least ten hours or more. Therefore, if the oxygen content is not controlled during this process, it will inevitably cause continuous oxidation of the filter element, especially the metal filter element, and The more serious the oxidation is in the final stage, which will eventually affect the use effect and service life of the filter element
