Drawings
Fig. 1 is the utility model discloses industry naphthalene loading tail gas absorbing device's schematic structure.
Wherein, 1 is the loading oil filling riser, 2 is the sprayer, 3 is the wash oil circulating tank, 4 are the wash oil circulating pump, 5 are first pipeline, 6 are the exhaust emission house steward, 7 are the heater, 8 are the governing valve, 9 are the second pipeline.
Detailed Description
In order to make the technical problem, technical scheme and beneficial effect that the utility model will solve more clearly understand, combine embodiment and attached drawing, it is right to go on further detailed description the utility model discloses. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.
As shown in fig. 1, the tail gas absorption device for industrial naphthalene loading comprises a loading crane pipe 1, an ejector 2, a wash oil circulation tank 3 and a wash oil circulation pump 4; wherein, loading oil filling riser 1 is connected through the gas inlet of first pipeline 5 with sprayer 2, and the gas outlet of sprayer 2 is connected with the import of wash oil circulation groove 3, and the wash oil export of wash oil circulation groove 3 is connected with the liquid inlet of sprayer 2 through second pipeline 9, and wash oil circulating pump 4 sets up on second pipeline 9, and the gas vent of wash oil circulation groove 3 is connected to exhaust emission house steward 6. A heater 7 is arranged in the washing oil circulating groove 3. The first pipe 5 is provided with a regulating valve 8.
The specific working process is as follows: gas generated by industrial naphthalene loading enters the ejector 2 after passing through the crane pipe, washing oil in the washing oil circulating groove 3 enters the ejector 2 through the washing oil circulating pump 4, tail gas of the industrial naphthalene loading is mixed and washed with the circulating washing oil in the ejector 2, and the purified tail gas enters the washing oil circulating groove 3 and then enters the tail gas discharge header pipe 6 to be discharged.
This device is through increasing sprayer 2, wash oil circulating groove 3, wash oil circulating pump 4 behind the industry naphthalene loading oil filling riser 1, with the mixed washing of industry naphthalene loading tail gas and circulation wash oil in the sprayer, the tail gas entering tail gas pipe net after the purification has reduced on-the-spot smell, has improved the absorption rate to industry naphthalene loading tail gas, has avoided the problem of dust cage jam simultaneously.
The above description is for further details of the present invention with reference to specific preferred embodiments, and it should not be understood that the embodiments of the present invention are limited thereto, and it will be apparent to those skilled in the art that the present invention can be implemented in a plurality of simple deductions or substitutions without departing from the scope of the present invention, and all such alterations and substitutions should be considered as belonging to the present invention, which is defined by the appended claims.
