The invention relates to a high-efficiency desulfurize syringe, belonging to the purifying separation technique. The invention comprises a transition tube, an overflow dam, a washing tube, a connecting bent pipe, and a separator which are connected in sequence. Wherein, the lower center of washing tube has a reverse nozzle; the bottom of separator has a fluid storage pot, while its top part has a gas outlet; the overflow dam, washing tube, connecting bent pipe and the separator are both made from carbon fiber glass steel; the inner wall of outer steel pipe of transition tube has the carbon fiber glass steel and the graphite brick as liner. The invention utilizes the carbon fiber glass steel to replace the high-efficiency desulfurize syringe made from H-alloy company, which has better abrasion resistance ability, longer service life, and lower cost. The invention improves the inner elements to improve the corrosion resistance ability, the separating ability and dust-cleaning effect. |
