Technical Field
The utility model relates to a high-temperature steam condensate recovery device, in particular to a steam condensate recovery device for refining titanium tetrachloride in a process of producing titanium tetrachloride by using titanium dioxide by a chlorination process.
Background
The method is characterized in that a boiling chlorination furnace is generally adopted as a chlorination reactor for producing titanium tetrachloride by using titanium dioxide by a chlorination method, petroleum coke and titanium-rich materials enter the chlorination furnace through pneumatic conveying, chlorine enters the chlorination furnace from the bottom through a chlorine distribution plate, the petroleum coke, the titanium-rich materials and the chlorine are in a fluidized state in the chlorination furnace for chlorination reaction, gas of titanium tetrachloride and other impurity metal chlorides generated by the reaction enters a flue gas pipeline, liquid titanium tetrachloride is sprayed on the flue gas pipeline for cooling, the metal chlorides in the flue gas are changed into solids from the gas, the flue gas enters cyclone separation for gas-solid separation, and the titanium tetrachloride in the gas is further subjected to solid removal and condensation to form crude titanium tetrachloride. Since crude titanium tetrachloride contains higher vanadium impurities, vanadium pollutes titanium white products and must be removed, the vanadium removal is realized by adding vanadium removing agents such as fatty acid or mineral oil in the process, and the process is called refining. In order to ensure the vanadium removal effect, the crude titanium tetrachloride is heated in a heater to 140-170 ℃, the heat source of the heater is water vapor with the pressure of 0.8-1.0Mpa, the temperature after the water vapor is condensed is 170-180 ℃, and most of the water vapor condensed water is discharged on site at present.
Disclosure of Invention

In order to achieve the above object, the high temperature steam condensate recovery device of the present utility model comprises a steam condensate discharge pipe, a circulating water tank and a circulating pump connected by a pipeline, and circulating water placed in the circulating water tank; the method is characterized in that: the lower section of a recovery cylinder is arranged in the circulating water, the tail end of a steam condensate water discharge pipe penetrates through the recovery cylinder and is arranged below the liquid level of the circulating water in the recovery cylinder, an outlet of a circulating pump is connected with a spray head through a circulating pipe, and the spray head is arranged in the recovery cylinder above the liquid level of the circulating water.
When the circulating water jet head is used, steam condensate is guided into the lower part of the liquid level of circulating water in the recovery cylinder through the steam condensate discharge pipe, and the liquid seal formed by the insertion depth of the steam condensate discharge pipe is utilized, so that the outlet pressure of the condensate is increased, the phenomenon that flash evaporation occurs due to the reduction of the outlet pressure of the condensate, secondary steam is generated, the low-temperature circulating water in the circulating water tank exchanges heat with high-temperature condensate, a large amount of circulating water takes away the heat of the condensate, and meanwhile, the jet head sprays in the recovery cylinder to prevent the pollution of the field environment caused by the overflow of a small amount of water steam;
as a further improvement of the utility model, the upper end of the recovery cylinder is fixedly provided with a sealing plate, and the circulating pipe passes through the sealing plate and is fixedly connected with the sealing plate; can thoroughly prevent the water vapor from overflowing and is convenient for fixing the recovery cylinder;
as a further improvement of the utility model, the circulating pipe is also connected with a circulating water tank connecting pipe; the circulating water tank connecting pipe is connected with the circulating water tank, and the cooled condensed water is used as water supplement of the circulating device, so that the addition amount of industrial water is reduced, and the condensed water is purified water without impurities, so that the dosage of the circulating water treatment is reduced, and the production cost of the circulating water is reduced;
in conclusion, the utility model can prevent the pollution of the site environment caused by the overflow of the water vapor, is beneficial to reducing the dosage of the circulating water treatment and can reduce the production cost of the circulating water.
