Abstract

The invention relates to a vacuum flashing and cooling device. The vacuum flashing and cooling device comprises a housing, a water cooling device and an inner components. According to the vacuum flashing and cooling device, flash-off steam is condensed after passing through a cooler. Thus, water in the flash-off steam can be effectively recovered. In addition, as the water cooling device is arranged inside the housing of a vacuum flashing tank, a traditional vacuum flashing tank and a vacuum flashing condenser can be integrated as a whole. Thus, floor space and a connection pipeline of the two devices are reduced, blocking of the vacuum flashing condenser is prevented, long-term operation of the system is enhanced, and equipment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of coal gasification equipment, in particular to a vacuum flash cooling device. Background technique [0002] Coal gasification technology is the most important production technology for producing syngas. After dry coal or wet coal is burned in a gasifier, the ash is quenched and washed to remove coarse slag, and the black water containing fine ash is passed through secondary or tertiary flash Heat is recovered by steaming to obtain gray water, which can be recycled as gasification washing liquid. Generally speaking, black water generally refers to the water containing a large amount of gasification residual carbon directly discharged from the bottom of the two parts of the gasifier and the scrubber; while gray water generally refers to the black water that has been treated by vacuum flash technology and precipitated to clarify and remove slag water obtained afterwards. [0003] The vacuum flash evaporatio...
