Description
Technical Field
The utility model relates to a one-level hydrogenation pre-converter that non-stop intensification was vulcanized belongs to coke-oven gas desulphurization unit technical field.
Background
The hydrogenation pre-converter is generally used in the desulfurization production of coke oven gas, a catalyst is arranged in the hydrogenation pre-converter for desulfurization, the active state of the catalyst is generally a reduction state, but the original catalyst is inconvenient to store and transport, so a catalyst manufacturer often passivates the catalyst and leaves a factory, the catalyst must be reduced before use, and the catalyst in the hydrogenation pre-converter cannot be used immediately after the catalyst is replaced due to short service cycle and poor later activity, and cannot be heated independently to promote the catalyst to be reduced, so that the catalyst needs to be stopped independently for heating and vulcanization after the catalyst is replaced, and the production cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes the defects in the prior art, provides a simple structure, and the one-level hydrogenation pre-converter which can complete the heating and vulcanizing operation without stopping.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a one-level hydrogenation pre-converter that does not stop and intensifies vulcanization, includes one-level hydrogenation pre-converter, and one-level hydrogenation pre-converter upper portion is provided with the inlet line, and the lower part is provided with the outlet line, is provided with bypass chilling line on the inlet line, is provided with bypass unloading pipeline on the outlet line, is provided with the intensifier water cooler on the unloading pipeline.
And an emptying valve is arranged on the bypass emptying pipeline.
The outlet end of the outlet pipeline is provided with a first-stage hydrogenation converter, and the outlet pipeline is connected with the first-stage hydrogenation converter.
Compared with the prior art, the utility model following beneficial effect has: the cold shock secondary line is added at the inlet, the outlet is connected with the temperature-raising gas-water cooler through the vent pipeline, the gas amount required during the vulcanization of the primary hydrogenation pre-converter is controlled by the high-temperature gas at the outlet of the original start-up heater and the normal-temperature gas of the cold shock secondary line, the temperature is adjusted by the cold shock secondary line, and the vulcanization pressure is controlled by the vent valve at the outlet of the temperature-raising gas-water cooler. Therefore, the temperature-rising vulcanization operation of the catalyst of the first-stage hydrogenation pre-converter can be finished without stopping, the catalyst can be replaced immediately when the activity of the catalyst is poor, the stopping treatment for overhaul is not required to be delayed, and the long-period operation of the system is ensured.

Detailed Description
As shown in figure 1, the utility model relates to a one-level hydrogenation pre-converter that intensification vulcanization is carried out without stopping, including one-level hydrogenation pre-converter 1, 1 upper portion of one-level hydrogenation pre-converter is provided with inlet line 2, and the lower part is provided with outlet line 4, is provided with bypass chilling pipeline 3 on the inlet line 2, is provided with bypass unloading pipeline 5 on the outlet line 4, is provided with the intensification ware water cooler on the unloading pipeline 5, is provided with the atmospheric valve on the bypass unloading pipeline 5, and outlet line 4 exit end is provided with one-level hydrogenation converter 6, and outlet line 4 links to each other with one-level hydrogenation converter 6.
The utility model discloses when using, required tolerance is by former heater export high temperature gas and the cold shock subline normal atmospheric temperature gas control of beginning to work when one-level hydrogenation pre-converter vulcanizes, and the temperature is adjusted by the cold shock subline, and the vulcanization pressure is controlled by intensification air water cooler export atmospheric valve. Therefore, the temperature-rising vulcanization operation of the catalyst of the first-stage hydrogenation pre-converter can be finished without stopping, the catalyst can be replaced immediately when the activity of the catalyst is poor, the stopping treatment for overhaul is not required to be delayed, and the long-period operation of the system is ensured.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
