Description
Technical Field
The utility model relates to the technical field of recovery processing equipment for cold rolling steam, in particular to a recovery processing device and a recovery processing system for cold rolling steam.
Background
In the rolling process of the metal plate strip, most of the emulsion is used as a process lubricating coolant. Due to the fact that a large amount of friction heat is generated in a deformation area in the cold rolling process, emulsion sprayed on the surface of a roller and the surface of strip steel is evaporated in a large amount, and smoke in a rolling area and the surrounding area is caused to be turbulent. If not removed, the vapors contaminate the environment, block vision, and form raindrop-like spot defects on the strip steel surface. This steam must be extracted.
Fig. 1 shows typical steam extraction routes, system equipment currently employed by cold rolling mills. The first fan 103 pumps steam generated at the cold roll 101 during rolling through a fan housing 102 to a cotton-wool or silk screen filtering device 105 through a pipeline and a valve 104. The second fan 106 in turn draws the filtered vapor from the filter assembly 105 and then exhausts it to the atmosphere through a stack 107. The collection tank 108 collects the emulsion produced in the above-described filtration process, and discharges it as a waste liquid to the waste liquid treatment station 109. The emulsion collected in the collection tank 108 is primarily water, oil and iron powder. The storage time is long at room temperature or outdoor low temperature, so the material is easy to deteriorate and denature.
The existing exhaust process and apparatus have the following problems: 1. consumes a large amount of water, which accounts for about 50 percent of the water consumption for process lubrication. 2. The oil is lost. The part oil consumption at least accounts for more than 20 percent of the total oil consumption. 3. The VOC content of the gas discharged from the chimney is high, the atmosphere is directly polluted, and odor is emitted when the atmosphere is serious.
Therefore, it is an urgent technical problem to be solved by those skilled in the art to design a recovery processing device and system for cold rolling steam, which can improve the efficiency of rolling steam processing.

Other objects and advantages of the present invention will become apparent from the following explanation of the preferred embodiments of the present application.
As shown in fig. 2 and 3, a cold rolling steam recovery processing apparatus includes a housing 218 and a gas discharge pipe 212. Wherein the housing 218 comprises a steam flow inlet 217 disposed at the top of the housing 218, a liquid flow outlet 213 disposed at the bottom of the housing 218, and a spiral partition 211 disposed between the steam flow inlet 217 and the liquid flow outlet 213, wherein the spiral partition 211 is configured to form a spiral-shaped cavity inside the housing 218.
The recovered vapor flows into the interior of the housing 218 via the vapor flow inlet 217 and down the helical cavity, where it gradually condenses as it flows downward and collects at the bottom liquid flow outlet 213.
The gas discharge pipe 212 is disposed inside the housing 218, the gas discharge pipe 212 penetrates the spiral cavity, a first end of the gas discharge pipe 212 extends to a lower side of the spiral cavity, and a second end of the gas discharge pipe 212 extends to an outer side of the housing 218. After the water in the steam is condensed, the rest of the gas components flow into the gas outlet pipe 212 from the first end of the gas outlet pipe 212 and flow out from the second end of the gas outlet pipe 212.
In order to accelerate the condensation efficiency of the moisture in the steam, a cooling medium inlet 215 is provided on the housing 218 for inputting a cooling medium into the housing 218. The cooling medium can be air or water. Preferably, the temperature reducing medium is cold air, and the cold air may be air at an ambient temperature or lower, for example.
The technical scheme of the utility model abandons the existing steam recovery treatment process, and greatly reduces the emission of pollutants by introducing a high-efficiency gas-liquid separation structure.
The utility model also provides a recovery processing system of the cold rolling steam, which comprises a recovery processing device 210 of the cold rolling steam, a fan cover 102, a first fan 103, a collection box 204 and a third fan 201.
The wind shield 102 is arranged on the upper side of the cold rolling roll 101, and the wind shield 102 is used for collecting emulsion steam generated by a rolling mill in the cold rolling process. The first fan 103 has an input end communicating with the hood 102 and an output end communicating with the steam inlet 217 of the housing 218, and the first fan 103 is used for conveying steam collected at the cold roll 101 into the inner cavity of the housing 218.
