The recovery device comprises a gas-solid separator and a solid product collector, wherein the solid product outlet of the gas-solid separator is communicated with the solid product inlet of the solid product collector, a solid product discharging valve is arranged on a pipeline which is used for communicating the gas-solid separator with the solid product collector, the gas product outlet of the gas-solid separator is connected with a gaseous product collector, and the outlet of a gaseous product subjected to secondary separation of the solid product collector is communicated with the gaseous product collector. The recovery device has the advantages of simple structure and convenience for operation; as the gas-solid separator is additionally arranged, the amount of waste gas carried and adsorbed by the solid product is reduced, the amount of waste gas in the solid product collected by the solid product collector is further reduced, the influence of the waste gas on subsequent processing of the solid product is avoided, and waste gas treatment steps are reduced; and meanwhile, the gaseous product (waste gas) is recycled, the utilization of chlorine gas is increased, and energy-saving and environment-friendly effects are achieved.
Description
Technical field
The utility model relates to the waste gas recovering device in a kind of chloridising production titanium dioxide process.
Background technology
In the chloride process titanium dioxide production process, oxidation reaction generates the gas-solid mixture of titanium dioxide and chlorine.When collecting titanium dioxide product, can be entrained with chlorine, chlorine produces certain influence to the product quality of titanium dioxide product following process.At present, handle titanium dioxide and carry the following dual mode of mainly containing of chlorine secretly: 1, external chloride process titanium dioxide enterprise uses the solid titania that dechlorination helical feed oxidation reaction generates, and this device fabrication required precision is high, the cost height.2, adopt the mode that the solid titania of oxidation reaction generation is washed, make the chlorine of carrying secretly soluble in water, and titania slurry dewatered, remove soluble impurity (comprising the product of chlorine after water-soluble), but this mode energy consumption is higher, equipment is perishable, the wastewater treatment difficulty after the processing.
Summary of the invention
The technical problems to be solved in the utility model provides the waste gas recovering device in a kind of chloridising production titanium dioxide process, this apparatus structure is simple, be convenient to operation, energy-conserving and environment-protective, production cost is low, can solve the problem of chlorine to the quality influence of equipment corrosion in the subsequent processes and product following process process.
Technical solution of the present utility model is:
A kind of chloridising is produced the waste gas recovering device in the titanium dioxide process, its special character is: comprise gas-solid separator and solid product gatherer, described gas-solid separator has the gas-solid mixture inlet, gaseous product outlet and solid product outlet, described solid product gatherer has the solid product import, solid product outlet after gaseous product outlet and the secondary separation after the secondary separation, the solid product outlet of described gas-solid separator is connected with the solid product import of solid product gatherer, on the pipeline of gas-solid separator and the connection of solid product gatherer, be provided with the solid product baiting valve, the gaseous product outlet of described gas-solid separator is connected with the gaseous products gatherer, and the gaseous product outlet is connected with the gaseous products gatherer after the secondary separation of described solid product gatherer.
On the pipeline that described gaseous products gatherer and gas-solid separator, solid product gatherer are communicated with, be respectively equipped with automatic regulating valve, to realize the continuous or step discharging of waste gas.
Described gas-solid separator is a bag hose.
The beneficial effects of the utility model:
Simple in structure, be convenient to operation, the gas-solid separator of setting up has reduced the exhausted air quantity that solid product carries, adsorbs, exhausted air quantity in the solid product of solid product gatherer further reduces, and has avoided the influence of waste gas to the following process treatment process generation of solid product, has reduced the exhaust-gas treatment link, simultaneously, realize the recycling of gaseous products (waste gas), improved the utilization rate of chlorine, played the effect of energy-saving and environmental protection.
