气体洗涤塔

The invention provides an anhydrous hydrogen fluoride production process; reaction raw materials fluorite powder and sulfate are mixed by an external mixer and enter into a converter with jacket; hot air with the temperature of 350 DEG C to 600 DEG C is fed in the jacket; the fluorite powder and the sulfate have chemical reaction and produce hydrogen fluoride; the produced hydrogen fluoride enters into a scrubber from a furnace header to be washed; the washed hydrogen fluoride enters into an intermediate tank from a condenser, and then receives distillation and degasification to prepare the finished product anhydrous hydrogen fluoride; solid residue is emitted from a furnace tail.

本发明提供一种无水氟化氢生产工艺，反应原料萤石粉及硫酸经外混器混合后进入带有夹套的转炉，向夹套内通入350～600℃的热风，萤石粉和硫酸在发生化学反应生成氟化氢，生成的氟化氢气体由炉头进入洗涤塔进行洗涤，洗涤后的氟化氢由冷凝器进入中间槽，然后经过精馏、脱气制得成品无水氟化氢；固体残渣由炉尾排出。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
