Title
(EN) RAILWAY TANK CAR FOR CONVEYING CONCENTRATED SULFURIC ACID
(FR) WAGON-CITERNE DESTINÉ À TRANSPORTER DE L'ACIDE SULFURIQUE CONCENTRÉ
(ZH) 一种浓硫酸铁路罐车
Abstract
(EN)
A railway tank car for conveying concentrated sulfuric acid comprises a tank (1), a manhole (9) provided on the tank (1), a liquid pumping apparatus (10), and a heating sleeve (2). The tank (1) comprises a front seal head (11), a cylinder (12), and a rear seal head (13). The heating sleeve (2) comprises a heating sleeve support (21) and a heating sleeve plate (22) covering the heating sleeve support (21). The heating sleeve support (21) comprises a T-shaped frame (211) and multiple arch-shaped supports (212). The arch-shaped supports (212) are disposed in parallel along the longitudinal direction of the cylinder (12), and are provided inside the T-shaped frame (211). Multiple vent holes (2121) are uniformly provided on the multiple arch-shaped supports (212) in a circumferential direction. At least one gas inlet hole (221) is provided at the bottom of the heating sleeve plate (22). At least one gas discharging hole (222) is provided on two respective sides at the top of the heating sleeve plate (22). A water discharging port (223) is provided at the lowest position on the bottom of the heating sleeve plate (22). A vent port (2122) is provided at two respective end portions of each of the arch-shaped supports (212). The invention resolves the issue in which an unreasonable structure of existing heating sleeve supports for a tank car results in ineffective use of steam during heating and longer heating times.

La présente invention concerne un wagon-citerne destiné à transporter de l'acide sulfurique concentré comprenant une citerne (1), une bouche (9) disposée sur le réservoir (1), un appareil de pompage de liquide (10) et un manchon chauffant (2). Le réservoir (1) comprend une tête d'étanchéité avant (11), un cylindre (12) et une tête d'étanchéité arrière (13). Le manchon chauffant (2) comprend un support de manchon chauffant (21) et une plaque de manchon chauffant (22) recouvrant le support de manchon chauffant (21). Le support de manchon chauffant (21) comprend une structure en forme de T (211) et de multiples supports en forme d'arc (212). Les supports en forme d'arc (212) sont disposés en parallèle le long de la direction longitudinale du cylindre (12) et sont disposés à l'intérieur du cadre en forme de T (211). De multiples trous d'aération (2121) sont disposés uniformément sur les multiples supports en forme d'arc (212) dans une direction circonférentielle. Au moins un trou d'entrée de gaz (221) est disposé au fond de la plaque de manchon chauffant (22). Au moins un orifice d'évacuation de gaz (222) est disposé sur deux côtés respectifs au sommet de la plaque de manchon chauffant (22). Un orifice d'évacuation d'eau (223) est disposé au niveau de la position la plus basse sur le fond de la plaque de manchon chauffant (22). Un orifice d'aération (2122) est disposé au niveau de deux parties d'extrémité respectives de chacun des supports en forme d'arche (212). L'invention résout le problème selon lequel une structure non raisonnable de supports de manchon chauffant existants pour un wagon-citerne conduit à une utilisation inefficace de vapeur pendant le chauffage et des temps de chauffage plus longs.
