Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing coal coking test equipment, in particular to a gas-liquid cooling device for raw coal gas. Background Art

[0002] During the laboratory low-temperature distillation of coal, the temperature of the raw coal gas escaping from the distillation furnace is about 600°C, so it needs to be cooled before it can be collected. If the traditional ammonia cooling process is used for cooling, it will not only increase the equipment construction cost, but also the scale of the laboratory low-temperature distillation of coal is small and there is no requirement for continuous production.

[0003] When optimizing the existing raw gas and gas-liquid cooling equipment, most of the optimization is reflected in the effect of the device on the raw gas and gas-liquid cooling. For example, the Chinese utility model patent with application number CN201320651959.2 discloses a "raw gas cooling device". The utility model patent sets up a cooling water pool, and the cooling water pool is provided with an internal cavity, an air inlet pipe, an air outlet pipe, and a cooling tower with an open bottom. The bottom of the cooling tower is inserted into the cooling water pool, and a nozzle is provided in the cooling tower cavity. The nozzle is connected to the outlet end of the water supply pipe, and the inlet end of the water supply pipe is connected to the cooling water pool. A water-cooling coil is provided in the cooling tower cavity, and the water inlet end of the water-cooling coil is connected to the outlet end of the water supply pipe, and the inlet end of the water supply pipe is connected to the cooling water pool. The water outlet end of the water-cooling coil is connected to the cooling water pool through a drain pipe, so as to cool the high-temperature raw gas safely and efficiently.

[0004] Although the above method has certain advantages in terms of improvement, it still has certain disadvantages: after the raw gas is cooled, impurities will be attached to the inside of the cooling tower. If there is no lifting device to remove the impurities from the inner wall, it will affect the effect of the next raw gas cooling. Utility Model Content
