Description
Technical Field
The utility model belongs to the technical field of clean production equipment, and particularly relates to a flue gas purifying device for calcined coke production.
Background
Calcined coke refers to petroleum coke calcined in a pot calciner to prepare calcined coke, and the purpose is that the petroleum coke entering the calciner is heated to generate carbonization reaction of carbon.
In the petroleum coke calcination production process, the generated flue gas mainly contains pollutants such as sulfur dioxide, nitrogen oxides, dust and the like. At present, most of the processes adopted by domestic carbon factories in the process of treating and purifying the calcined flue gas are as follows: the high-temperature sncr denitration (or scr denitration in a low-temperature region) +exhaust-heat boiler+bag-type dust collector+fan pressurization+wet desulfurization of the calcined flue gas often causes the problem of blockage of the bag-type dust collector. The moisture content of the calcination flue gas is as high as 10%, and the flue gas contains trace tar organic matters, so that the calcination flue gas is sticky and is easy to form blockage in the filter bag, and the filter bag needs to be replaced once in about 4-6 months. After the filter bag is replaced, the manhole door is opened, the temperature in the passage is reduced to below 40 ℃, the filter bag can be disassembled, when the filter bag is disassembled, the bag cage is firstly taken out, then the spring ring at the upper opening of the filter bag is pinched into a concave shape, the filter bag is pulled upwards, and before a new filter bag is installed, dust on the hole of the pattern plate is cleaned. Then, the filter bag and the dust removing framework are installed, and the installation of the bag cage and the filter bag is the minimum and careful obligation in the intensive installation, so that the filter bag is not collided with a sharp object or hooked when being installed, and even if the filter bag is scratched, the service life of the filter bag is greatly shortened. The method for installing the filter bag is that firstly, the filter bag is put into a bag chamber from a flower plate hole of a box body, then a spring ring at the upper part of a bag opening is pinched into a concave shape, the concave shape is put into a flower plate hole of the box body, and then the spring ring is restored to tightly press the circumference of the flower hole, and finally, a bag cage is silently punctured from the bag opening until a protecting cover at the upper part of the bag cage is really pressed on the flower plate hole in the box body. To prevent the filter bags from being stepped on, a bag cage is required to be arranged every time a filter bag is arranged.
The operation flow is complex, time and labor are wasted, and the production process is required to be stopped for operation, so that the operation of replacing the filter bag brings trouble to the stability of the production process, and meanwhile, the operation cost is increased.
At present, the domestic treatment technology is to add an electric tar precipitator or a plasma reactor in front of a filter bag dust collector, realize the purpose of removing tar by using electric field force through the charged tar molecules in the flue gas, reduce the concentration of tar in the flue gas as much as possible and reduce the influence on the filter bag dust collector. The main problem of the technology is that the temperature of the flue gas after the waste heat boiler is not easy to be too low, otherwise, the flue gas is condensed to cause corrosion, and the higher flue gas temperature is unfavorable for the collection of tar in an electric field, so that the collection efficiency is low. In the actual operation process, the filter bag blockage problem still occurs in the flue gas treated by the electric tar precipitator and the plasma reactor.
