Embodiment Construction
[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0039] Such as figure 1 and figure 2 As shown, the dust-containing high-temperature oil-gas washing and cooling device includes:
[0040] The washing tower 1 is provided with a grid 4 in the middle, which divides the inner cavity of the washing tower 1 into a lower washing area 11 and an upper spraying area 13 .
[0041] A spraying device 3 is provided in the spraying area 13, and the inlet of the spraying device 3 is connected to the external spraying liquid pipeline 31; there are three spraying devices in this embodiment, arranged at intervals along the height direction of the spraying area. The spraying device can be selected from any one of the prior art as required.
[0042] The spray pipe 31 is provided with a first regulating valve 32 for regulating the flow rate of the spraying medium; correspondingly, a first temperature detector ...

The invention relates to a dust-containing high temperature oil gas washing and cooling device and a washing and cooling method. The device comprises a washing tower. The lateral wall of the washing tower is connected to a washing gas inlet pipe. The device is characterized in that grids are arranged in the washing tower. The grids separate the inner cavity of the washing tower into two parts: the upper part (spraying area) and the lower part (washing area). The washing gas inlet pipe is connected to the washing area. A spraying device is arranged in the spraying area. The inlet of the spraying device is connected to an external spraying liquid pipeline. A defoamer is arranged in the spraying area and is right above the spraying device. The bottom of the washing tower is connected to an oil discharge pipeline. The top of the washing tower is connected to a light oil gas pipeline. The provided device utilizes the light oil separated from coal tar gas to circularly spray high temperature coal tar gas so as to cool the high temperature coal tar gas, thus the cooled coal tar gas can be further separated; no extracting agent is added during the process, the separation is simplified therefore, the ash content of oil gas is reduced, the corrosion degree of devices is reduced, and the separation cost is reduced.
Description
technical field [0001] The invention relates to a high-temperature oil-gas washing system and a washing method, in particular to a dust-containing high-temperature oil-gas washing and cooling device and a washing and cooling method. Background technique [0002] For some chemical plants, such as coal hydropyrolysis, the product is high-temperature oil and gas that also contains coal ash; the separation of such mixtures is currently a difficult problem. [0003] In the current separation technology of high-temperature coal tar gas mixture, it is mainly separated by adding various solvents, but the addition of solvents not only increases the side reactions in the equipment, but also increases the difficulty and cost of separation, and brings Corrosion of equipment, at the same time, due to the high ash content of high-temperature coal tar gas, it is easy to cause blockage of equipment. Contents of the invention [0004] The technical problem to be solved by the present inve...
