Abstract
The utility model discloses a benzol scrubbing system, which comprises a benzol scrubbing tower and a dehydration tower, wherein the front segment of the benzol scrubbing tower is provided with a fan and an electric fishing, the fan is communicated with the benzol scrubbing tower, the electric fishing is communicated with the fan, the electric fishing is provided with a coal gas inlet and a coal gas outlet, the coal gas outlet of the electric fishing is communicated with the fan, the fan is communicated with the lower portion of the benzol scrubbing tower, the lower portion of the electrical fishing is provided with a condensed fluid outlet, the condensed fluid outlet is communicated with the upper portion of the benzol scrubbing tower, the lower portion of the benzol scrubbing tower is provided with a rich oil outlet, the rich oil outlet is communicated with the dehydration tower, and enters the benzol scrubbing tower after being mixed with condensed fluid which enters the benzol scrubbing tower through a lean oil outlet on the dehydration tower. The benzol scrubbing system using the structure absorbs crude benzol in the coal gas through lean oil in the benzol scrubbing tower, also uses the condensed fluid of the electrical fishing on the front portion of the fan to scrub benzol in a final cooling tower, thereby increasing the recovery rate of the crude benzol, stabilizing the production of the crude benzol, and reducing the consumption of the lean oil.
Description
Technical field
The utility model belongs to a kind of benzene series system of washing of coal tar factory.
Background technology
Wash the benzene series system at present and just adopt the oil-poor crude benzol that absorbs in the coal gas, this system is not fine to coal gas crude benzol assimilation effect, and the rate of recovery of crude benzol is lower.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of both washing in the benzene tower with washing oil to absorb crude benzol in the coal gas, utilizes again that the phlegma of electric fishing goes final cooling tower to wash benzene before the blower fan, has improved the rate of recovery of crude benzol.
The utility model is achieved through the following technical solutions:
A kind of benzene series system of washing, comprise and wash benzene tower and debenzolizing tower, be provided with blower fan that is communicated with it and the electric fishing that is communicated with blower fan at the leading portion of washing the benzene tower, electric fishing is provided with gas entry and gas exit, the gas exit of electric fishing is communicated with blower fan, blower fan is communicated with the bottom of washing the benzene tower, the bottom of electric fishing is provided with condensate outlet, this condensate outlet with wash benzene tower top and be communicated with, the bottom of washing the benzene tower is provided with the rich oil outlet, rich oil outlet is communicated with debenzolizing tower, washes the benzene tower by the oil-poor outlet on the debenzolizing tower with entering to enter after the phlegma of washing the benzene tower mixes again.
The utility model has the advantages that:
Adopt the benzene series of washing of said structure to unite, in washing the benzene tower, both used the crude benzol in the oil-poor absorption coal gas, utilize the phlegma of the preceding electric fishing of blower fan to go final cooling tower to wash benzene again, improved the rate of recovery of crude benzol thus, stablize crude benzol production, reduce oil-poor consumption.
Description of drawings
Figure is the utility model structural representation.
Embodiment
Embodiment: wash the benzene series system as shown in the figure, comprise and wash benzene tower 3 and debenzolizing tower 4, be provided with blower fan 2 that is communicated with it and the electric fishing 1 that is communicated with blower fan 2 at the leading portion of washing benzene tower 3, electric fishing 1 is provided with gas entry and gas exit, the gas exit of electric fishing 1 is communicated with blower fan 2, blower fan 2 is communicated with the bottom of washing benzene tower 3, the bottom of electric fishing 1 is provided with condensate outlet, this condensate outlet with wash benzene tower 3 tops and be communicated with, the bottom of washing benzene tower 3 is provided with the rich oil outlet, rich oil outlet is communicated with debenzolizing tower, washes benzene tower 3 by the oil-poor outlet on the debenzolizing tower 4 with will entering to enter after the phlegma of washing benzene tower 3 mixes again.
Coal gas enters electric fishing 1 back entering by blower fan 2 and washes benzene tower 3 bottoms, and the phlegma of electric fishing 1 enters and washes benzene tower 3 tops whole cold wash benzene tower, in washing benzene tower 3 with the crude benzol in the oil-poor absorption coal gas, oil-poor behind the crude benzol after the absorption just become rich oil, rich oil enters in the debenzolizing tower 4 again and takes off benzene, the rich oil that takes off behind the benzene has just become oil-poor, is oil-poorly mixed the back circulation again with phlegma and enters and wash benzene tower 3 by what debenzolizing tower 4 came out.
Claims (1)
1. wash the benzene series system for one kind, comprise and wash benzene tower and debenzolizing tower, it is characterized in that: be provided with blower fan that is communicated with it and the electric fishing that is communicated with blower fan at the leading portion of washing the benzene tower, electric fishing is provided with gas entry and gas exit, the gas exit of electric fishing is communicated with blower fan, blower fan is communicated with the bottom of washing the benzene tower, the bottom of electric fishing is provided with condensate outlet, this condensate outlet with wash benzene tower top and be communicated with, the bottom of washing the benzene tower is provided with the rich oil outlet, rich oil outlet is communicated with debenzolizing tower, washes the benzene tower by the oil-poor outlet on the debenzolizing tower with entering to enter after the phlegma of washing the benzene tower mixes again.
