Embodiment

[0029]Embodiment: By pumping the liquid in the raw material water tank 1 into the carbon-water mixing tower 2, mixing water and coal at high temperature to form a coal mixed gas, leading the coal mixed gas into the synthesis tower 3, and mixing the coal mixed gas with high temperature The high temperature is converted into methanol gas, and the methanol gas is diverted into the mixed gas preheating sleeve 9 through the synthetic carbon water drainage tube 10, and the raw coal mixed gas is preheated by the methanol gas in the mixed gas preheating sleeve 9, and the methanol gas is The heat in the coal is transferred to the mixed gas of raw material coal, thus avoiding the loss of heat, the methanol gas is diverted into the cooling tower 4 through the carbon water cooling drainage pipe 11, and the neutralized liquid in the cooling mixed liquid tank 5 is pumped through the cooling pump 6 Into the drainage shunt pipe 7, through the drainage shunt pipe 7, the neutralization liquid is...

Abstract

The invention discloses a waste heat recovery device for methanol production, which comprises a raw material water tank, a carbon-water mixing tower, a synthesis tower and a cooling tower, the raw material water tank is connected to the carbon-water mixing tower, the synthesis tower is connected to the carbon-water mixing tower through a preheating structure, the cooling tower is connected to thesynthesis tower, the cooling tower and the synthesis tower are connected to the preheating structure, a cooling structure is arranged in the cooling tower, a water preheating structure is arranged onthe cooling structure, and the water preheating structure is arranged at the joint of the raw material water tank and the carbon-water mixing tower in a sleeving manner; the device has the beneficialeffects that heat in the methanol mixed gas is transferred into the coal mixed gas through the preheating structure, the heat of the methanol mixed gas is transferred into water in the coal mixed gasthrough the water preheating structure for preheating, a large amount of heat is prevented from being lost, and the methanol gas is rapidly cooled through the cooling structure; meanwhile, neutralizing and cooling are combined together, cooling is accelerated, and meanwhile the production time is shortened.

Description

technical field [0001] The invention relates to the technical field of methanol production, in particular to a waste heat recovery device for methanol production. Background technique [0002] Methanol is an important chemical basic product and organic chemical raw material. It is a colorless and volatile liquid with an alcohol smell. It is used to manufacture formaldehyde and pesticides, and is also used as an extraction agent for organic matter and a denaturant for alcohol. In the methanol manufacturing process, especially when coal is used to produce methanol, a large amount of high-temperature steam will be generated, and various waste heat recovery equipment have different effects on the recovery of high-temperature steam waste heat. Equipment with high recovery efficiency is more energy-saving and environmentally friendly. In view of this, in-depth research on the above-mentioned issues resulted in this case. Contents of the invention [0003] The object of the pres...
