Abstract
The utility model discloses a wash oil capture tower. The wash oil capture tower comprises a wash oil collector (14), a gas distributor (12), high-efficiency pore plate padding (11), a vortex baffling demister (5) and a screen mesh skimmer (6). The wash oil collector is located at the bottom of a tower body (3) and provided with an oil guide plate (8) and an oil outlet (15). The gas distributor (12), the high-efficiency pore plate padding (11), the vortex baffling demister (5) and the screen mesh skimmer (6) are sequentially arranged on the wash oil collector. A gas collecting chamber (7) is disposed on the screen mesh skimmer. An oil guide pipe (4) is positioned at the bottom of the vortex baffling demister, one end of the oil guide pipe is communicated with the vortex baffling demister, and the other end of the oil guide pipe is communicated with the oil guide plate. After wash oil is captured by the wash oil capture tower, the amount of wash oil in coking gas is smaller than or equal to 30mg/m<3>. The wash oil capture tower not only is capable of improving combustion calorific value efficiency of coking gas and reducing gas consumption and exhaust emission, but also is capable of increasing the amount of recycled wash oil, lowering production cost, reducing erosion to gas appliances, and prolonging service life of equipment.
Description
Technical field
The utility model relates to the gas purification treating apparatus, especially relates to the coke gas washing oil and captures tower.
Background technology
Can make industrial fuels such as coke, raw gas and tar by the cracking of smart coal-fired process.And raw gas generally will pass through cold drum, desulfurization, deamination, take off benzene washing and sewage disposal just can be produced coke gas.Coke gas all is will carry out washing oil to capture through washing after the benzene tower comes out, and makes pure coke gas as industry and domestic fuel with the washing oil of removing in the coke gas.At present, the washing oil that is used for coke gas captures tower and mainly has following problem, and the one, complex structure, manufacturing cost is high, and installation and maintenance are not quite convenient; The 2nd, washing oil capture effect is not very good, and the washing oil amount is on the high side in the coke gas, influences the combustion efficiency of coke gas, and equipment and combustion are produced corrosiveness, and the burning meeting produces pernicious gas, and environment is had bigger pollution; Cause in the production process oil washing consumption too much, increase the enterprise production cost.
The utility model content
Capture the existing problem of tower to coke gas washing oil in the above-mentioned prior art, the utility model provides a kind of not only compact conformation, and manufacturing cost is lower, and the washing oil capture is effective, and the washing oil that the coke gas depuration quality is high captures tower.
The technical scheme that the technical problem that the utility model will solve is taked is: said washing oil captures tower and comprises washing oil gatherer, gas distributor, efficient orifice plate filler, whirlwind baffling demister and wire mesh demister; Said washing oil gatherer is positioned at the tower body bottom and has oil guide plate and oil-out; On the washing oil gatherer, be disposed with gas distributor, efficient orifice plate filler, whirlwind baffling demister and wire mesh demister; Wire mesh demister is provided with gas collection chamber, is provided with an end and whirlwind baffling demister is connected, the other end is connected with oil guide plate oil guide pipe in whirlwind baffling demister bottom.
The washing oil that the utility model removes is because in gravitational settling to the washing oil gatherer; Reach to enter automatically after certain liquid level to pump in the oil-washing tank and by oil pump and wash the benzene operation; Said washing oil captures in the tower and disposes corresponding jet chimney, uses instead so that washing oil capture tower is regularly carried out purge, block clearing and maintenance.
After the said washing oil of the utility model captures tower capture washing oil, washing oil amount≤30mg/m3 in the coke gas.Not only can improve the combustion heat value efficient of coke gas, reduce gas consumption, reduce toxic emission; And can increase the washing oil recovery, and reduce production costs, can reduce erosion simultaneously to burner; Prolong service life of equipment, the utility model is simple and compact for structure, and manufacture, installation, maintenance are convenient.
The course of work of the utility model is: coke gas is through after washing the benzene tower; Come out to get into the gas distributor that washing oil captures the tower bottom from washing the benzene top of tower; After the efficient orifice plate filler of process removes the washing oil that particle is bigger in the coke gas; Coke gas passes through whirlwind baffling demister again; Whirlwind baffling demister is caught most washing oil particle in the coke gas, removes the washing oil that gets off and is flow in the washing oil gatherer by the oil guide pipe that links to each other with whirlwind baffling demister, and coke gas is handled through the silk screen demister again; Remove that diameter is the mist washing oil drop of 3-5um in the coke gas, the coke gas after washing oil captures gets into and flows out the entering next process in the gas collection chamber at tower body top and from the gas outlet.
