Sealed continuous slag discharging device for boiling chlorination production of titanium tetrachloride gravity dust collector

Abstract

The invention discloses a sealed continuous slag discharging device for boiling chlorination production of a titanium tetrachloride gravity dust collector. The sealed continuous slag discharging device mainly consists of a device case, a slag discharging pipe, a shaft sleeve tube, a shaft, a bearing, a protection ring, a hollow turbine, a press cover, a dust collecting slag scraper, a worm rod, adriving device, a slag blocking ring and a flange, wherein a flange is arranged on the top of the case and is connected with the bottom of a dust collector; the slag discharge pipe is welded under a bottom plate of the case; the slag blocking ring is welded in the bottom plate of the device case; the shaft sleeve tube is welded in the center position of the bottom plate of the case; the shaft, thepress cover and the bearing are mutually matched and are arranged in the shaft sleeve tube; the protection ring is welded in a connecting position of the case and the bottom plate; the hollow turbineis arranged on the shaft; the dust collection slag scraper is arranged under the hollow turbine; the hollow turbine is matched and connected with the worm rod; the worm rod and the driving device areconnected. By using the device, the sealed, continuous and automatic discharge of the dust collection slag can be realized.

Description

technical field [0001] The invention belongs to the technical field of titanium tetrachloride production, in particular to a closed slag discharge device for a gravity dust collector used in the process of boiling chlorination to produce titanium tetrachloride. Background technique [0002] At present, in the domestic and foreign industrial production of titanium tetrachloride, most dust collectors use cyclone dust collectors and gravity dust collectors. The dust collectors used in domestic titanium tetrachloride production technology are mainly gravity dust collectors. Mainly, there are various discharge devices for dust collection and slag collection in gravity dust collectors. So far, there is no automatic slag discharge device that can realize continuous and airtight discharge. Most of them use self-made, semi-automatic and supplemented by manual discharge. Some enterprises also use relatively primitive manual discharge of dust collection slag, which is relatively labor-...

Problems solved by technology

[0002] At present, in the domestic and foreign industrial production of titanium tetrachloride, most dust collectors use cyclone dust collectors and gravity dust collectors. The dust collectors used in domestic titanium tetrachloride production technology are mainly gravity dust collectors. Mainly, there are various discharge devices for dust collection and slag collection in gravity dust collectors. So far, there is no automatic slag discharge device that can realize continuous and airtight discharge. Most of them use self-made, semi-automatic and supplemented by manual discharge. Some enterprises also use relatively primitive manual discharge of dust collection slag, which is relatively labor-intensive and may easily cause scald accidents caused by dust collection slag. The operating environment is relatively harsh, causing certain pollution to the surrounding environment; the discharged dust collection slag adopts a regular discharge process, resulting in part of the titanium tetrachloride being miscible with the deposited dust collection slag and causing condensation at the bottom of the dust collector. Occurrence of dripping and leaking, resulting in unorganized discharge of chlorine-containing waste gas; due to the occurrence of condensation of titanium tetrachloride, the discharged dust residue contains a small amount of titanium tetrachloride, and dry residue treatment cannot be realized, and a large amount of titanium tetrachloride must be used immediately Rinse with alkaline water or clear water to collect dust and residue, and produce a large amount of acidic waste water and chlorine-containing waste gas. The treatment of waste water and waste gas will increase the production cost, which is not conducive to the establishment of energy saving and emission reduction of enterprises
