Abstract
The utility model discloses a titanium dioxide suspension air current cooling device, including multisection cooling duct and pipe case, the cooling duct comprises center tube and sleeve pipe, and high temperature titanium dioxide suspension air current gets into the cooling duct center tube, and the cooling water gets into the cooling duct sleeve pipe, relies on the cooling water to take away the heat, makes titanium dioxide suspension gas flow temperature obtain reducing. The rapid cooling cooling of high temperature titanium dioxide suspension air current can be realized to this device, makes high temperature titanium dioxide suspension air current become the low temperature air current through the heat exchange, has satisfied the technology demand. And this device heat exchange efficiency is high, utilize short cooling duct can make the cooling rapidly of high temperature titanium dioxide suspension air current.
Description
Technical field
The utility model relates to the corollary apparatus that a kind of chlorination process produces titanium dioxide, relates more specifically to a kind of high temperature titanium dioxide suspending air flow cooling unit.
Background technology
Chlorination process prepares the main method of high-grade rutile titanium white powder, and titanium tetrachloride generates titanium dioxide and chlorine through gaseous oxidation in oxidation reactor, obtains content of titanium dioxide and is about 30%(massfraction) suspension air-flow.Titanium dioxide in suspension air-flow, up to more than 1000 DEG C, in order to ensure that titania can not continue to grow up, and is separated by the suspension gas flow temperature shifted out from oxidation reactor, and technique needs suspension air-flow sharply to cool to less than 200 DEG C.
The method of cooling of titanium dioxide suspending air-flow is immersed in cooling trough by titanium dioxide suspending gas pipeline traditionally, relies on the flowing of water trough inner water to be taken away by heat.Because heat exchange efficiency is lower, therefore heat interchanging area is comparatively large, needs the psychrophore grown to meet process requirements very much.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of chlorination process efficiently and produces titanium dioxide suspending air flow cooling unit.
The technical scheme that the utility model adopts is: titanium dioxide suspending air flow cooling unit, comprise psychrophore and bobbin carriage that more piece connects successively, high temperature titanium dioxide suspending air-flow enters psychrophore and bobbin carriage successively, rely on the water coolant in psychrophore to be taken away by heat, titanium dioxide suspending gas flow temperature is reduced.
Further, bobbin carriage is relied on to connect between described psychrophore.
Preferably, described psychrophore is by pipe core and outer sleeve composition thereof.
Further, described high temperature titanium dioxide suspending air-flow enters pipe core and the bobbin carriage of described psychrophore.
Further, the water coolant in described psychrophore enters the sleeve pipe of psychrophore.
Further, the described sleeve pipe of the cooling-water flowing in described psychrophore through connecting successively is discharged.
Preferably, described psychrophore joint number is 2-7 joint.
Preferably, described bobbin carriage number is 1-6.
The beneficial effects of the utility model are: this device can realize the chilling cooling of high temperature titanium dioxide suspending air-flow, makes high temperature titanium dioxide suspending air-flow become low-temperature airflow by heat exchange, meets process requirements.And this device heat exchanger effectiveness is high, utilize shorter psychrophore can make the rapid cooling of high temperature titanium dioxide suspending air-flow.

Embodiment
Embodiment of the present utility model is introduced further below in conjunction with accompanying drawing.
As shown in Figure 1, this titanium dioxide suspending air flow cooling unit, comprises three joint psychrophores, 1,2,3 and two bobbin carriages I, II, relies on bobbin carriage to connect successively between psychrophore.
Psychrophore 1,2,3 forms by pipe core A and outer sleeve B thereof.Psychrophore pipe core A is provided with airflow inlet A
1with outlet A
2, the sleeve pipe B of psychrophore is provided with entrance of cooling water B
1with outlet B
2, be connected in series by pipe connecting 4,5 successively by the import of the outlet of a upper sleeve pipe and next sleeve pipe between sleeve pipe B.
High temperature titanium dioxide suspending air-flow enters the pipe core A of psychrophore and the bobbin carriage I of connection thereof, and the water coolant for lowering the temperature enters the sleeve pipe B of psychrophore.Rely on the water coolant in psychrophore sleeve pipe B the heat of high temperature titanium dioxide suspending air-flow can be taken away, titanium dioxide suspending gas flow temperature gets final product rapid cooling.
The high temperature titanium dioxide suspending air-flow of rapid cooling is discharged through the pipe core outlet of final section psychrophore 3; Cooling-water flowing in psychrophore is through series connection sleeve pipe final section cannula exit discharge mutually.
Specific embodiment: the high temperature titanium dioxide suspending air-flow of 1050 DEG C enters the pipe core A of psychrophore 1, flow velocity is the water coolant of 3m/s enters psychrophore 1 sleeve pipe B from high temperature side, due between psychrophore 1 and psychrophore 2, between psychrophore 2 and psychrophore 3, be connected with bobbin carriage II respectively by bobbin carriage I, adjacent psychrophore 1, psychrophore 2, be connected in series between the sleeve pipe B of psychrophore 3, water coolant is drawn from the cannula exit of low temperature side psychrophore 3, carry away heat, titanium dioxide suspending gas flow temperature drops to 190 DEG C at refrigerating unit outlet temperature.
