Description
Technical field
The utility model relates to the chemical mechanical equipment field, relates in particular to a kind of gas quench system.
Background technology
What gas quench system was the most commonly used is tubular heat exchanger, but some special occasions in Chemical Manufacture, as: produce in the white carbon process at fluorine-containing white residue; Can produce a large amount of 100 ℃ of ammonias and steam (hereinafter to be referred as hot ammonia gaseous mixture, obtain gaseous mixture after the cooling and be called cold ammonia gaseous mixture) during the silica dissolving, hot ammonia gaseous mixture adopts tubular heat exchanger to carry out heat exchange and obtains cold ammonia gaseous mixture entering postorder operation; After using a period of time, a large amount of hot ammonia gaseous mixtures will be taken a certain amount of ammonium fluosilicate solution out of, attached on the heat exchanger tube wall; In a large amount of ammonia environments, can separate out silica, stop up tubulation; Cause heat exchanger to occur stopping up; Influence the heat exchange effect, the cold ammonia mixture temperature that causes getting into after the heat exchange next process is too high, and follow-up workshop section cooling difficulty relatively; Thereby cause crystallization meticulous, influence product quality.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned shortcoming and a kind of gas temperature that can reduce is provided, and reduces heat exchanger and stops up, and improves heat exchanger heat exchange effect, thereby reaches the gas quench system that improves product quality and yield.
The purpose of the utility model and solve its technical problem underlying and adopt following technical scheme to realize:
The gas quench system of the utility model; Comprise cooling tower, circulating pump, tubular heat exchanger; Wherein: cooling tower is a packed tower; Its bottom is provided with the cooling tower storage tank, the middle part is a packing layer, and the tube wall between bottom cooling tower storage tank top and the packing layer is provided with air inlet pipe, the top is provided with escape pipe, the packing layer top be provided with feed tube; Feed tube is connected with the outlet of tubular heat exchanger tube side, and cooling tower storage tank outlet at bottom links to each other with the import of tubular heat exchanger tube side, and cooling tower storage tank outlet at bottom is provided with circulating pump, saturated ammonia water discharging valve with the pipeline that is connected of tubular heat exchanger tube side import.
The above-mentioned gas cooling device, wherein: tubular heat exchanger cooling water inlet and coolant outlet are respectively equipped with valve A, valve B.
The above-mentioned gas cooling device, wherein: pump inlet and outlet are respectively equipped with valve C, valve D.
The utility model compared with prior art has tangible advantage and beneficial effect.Can be known that by above technical scheme hot ammonia gaseous mixture directly cools with cold ammoniacal liquor saturated solution direct counter current contacting in packed tower and obtains cold ammonia gaseous mixture, being provided with of circulating pump strengthened the flow velocity that passes through the cooling tower cooling medium, improved cooldown rate greatly.Hot ammonia gaseous mixture carries out heat exchange at cooling tower and no longer passes through tubular heat exchanger, thereby reduces the obstruction of tubular heat exchanger, improves heat exchanger heat exchange effect, has improved system operating ratio and efficient, improves product quality and yield thereby reach.
