Description

Tar collecting device of carbon roasting flue gas purification cooling tower

Technical Field

The utility model belongs to plain goods processing application apparatus field of charcoal especially relates to a plain calcination gas cleaning cooling tower tar collection device of charcoal.

Background

In the carbon industry, a large amount of asphalt smoke and dust are volatilized and emitted in the asphalt melting, kneading, molding, roasting and other processes. The asphalt smoke is a mixture of a large amount of liquid and a small amount of gaseous polycyclic aromatic hydrocarbon hydrocarbons generated in the production and processing processes of the industries of carbon and electrolytic aluminum, contains more than 80 polycyclic aromatic hydrocarbon substances such as 3, 4 benzopyrene, benzanthracene, carbazole and the like, is mostly carcinogenic and strong carcinogenic, has a particle size of 0.1-1.0 mu m mostly, is only 0.01 mu m at the minimum and is about 10.0 mu m at the maximum.

Roasting is an important process in the production process of carbon products. In the roasting process, coke powder is used as a protective medium in a roasting furnace, and the roasting furnace is heated to the maximum roasting temperature of 1200-1300 at a certain heating rate under the condition of air isolation according to the technical requirements of products. Meanwhile, the temperature of the flue gas is extremely unstable and is usually between 80 and 300 ℃. The graphite electrode uses coke powder and medium temperature coal pitch as raw materials, and the coke powder and the medium temperature coal pitch are mixed according to a certain proportion and then pressurized to prepare a green compact. The roasting fuel adopts natural gas, and the roasting furnace is of a ring-type roasting furnace structure. And (2) loading the green blocks subjected to pressure forming into an 8-chamber roasting furnace, filling coke powder serving as a protective medium between the green blocks, and roasting at high temperature for a certain time to obtain the carbon product, wherein the coke powder is 1200-1300 ℃. Because the main raw materials of the green compact are coke powder and asphalt, a large amount of asphalt smoke and smoke can escape in the roasting process. A source of contaminants during calcination.

The roasting furnace adopts natural gas as fuel, and in the roasting process, besides smoke dust and SO generated by combustion of the natural gas, asphalt in the carbon green compact blocks can emit a large amount of asphalt smoke due to high-temperature pyrolysis. In the heating and temperature rising stage at the initial stage of roasting, the main pollutants are smoke dust and SO; the middle heating period is an asphalt volatilization period, and the main pollutants are asphalt smoke (containing benzopyrene, benzanthracene, carbazole and the like); the main pollutants in the later stage of roasting are smoke dust, SO and a small amount of asphalt smoke. Pollutants such as smoke dust, SO, asphalt smoke and the like generated in the roasting process are collected by a smoke collection channel and then are discharged from a chimney at high altitude. Selecting a flue gas purification process: the smoke generated by the carbon roasting furnace has complex components, asphalt smoke, smoke dust and SO are between 80 and 300 ℃, and the working condition of the smoke has different degrees of influence on various purification methods of the asphalt smoke.

In order to solve the problem of the flue gas, people treat the flue gas by arranging a carbon roasting flue gas purification cooling tower, and most of discharged tar is collected by adopting a manual cleaning method at present. The prior art adopting manual tar collection technology has the following problems: 1. when the bottom tar is hardened and condensed into blocks, the bottom tar of the cooling tower is manually cleaned by an iron shovel, and the bottom tar can only be heated by connecting the rubber pipe with external steam, so that the steam utilization rate is reduced along with the aging phenomenon of the rubber pipe after long-term use or improper use of the rubber pipe; when tar is softened, the tar is removed by a shovel with an iron shovel, so that the labor intensity of workers is high and the operation of the workers is complicated in the removing process; 2. because production equipment needs to be opened when bottom tar is manually cleaned, negative pressure communicated between the interior of the equipment and the outside is seriously lost; 3. when tar is collected, the internal liquefied tar is discharged together with condensed water, and a lot of liquefied tar is mixed in the water, so that splashing is easily caused in the discharge process, and certain pollution is caused to the environment.

In order to solve the problem of hardening of tar, people use steam to heat to soften the tar, so that oil-water separation is realized, and the purpose of separating the tar is further achieved.
