Abstract
The utility model discloses a Venturi scrubber for scrubbing calcined tail gas of titanium white by a sulfuric acid process, comprising an inlet pipe (1), a shrinkable tube (2), a choke (3), an expanding tube (4), a liquid-receiving groove (5) and a main nozzle (6), wherein the inlet pipe (1), the shrinkable tube (2), the choke (3) and the expanding tube (4) are connected into a main pipe body in sequence; the lower end of the main pipe body is connected with the liquid-receiving groove (5) which is provided with a gas outlet (5a); the main nozzle (6) is arranged on the shrinkable tube (2); and the choke (3) is provided with a ring nozzle (7). The Venturi scrubber has simple structure and obvious effect, can effectively guarantee the temperature-reducing effect, and prevent an electric demister from collapsing and further being scrapped due to the excess of working temperature.
Description
Technical field
The utility model belongs to the chemicals apparatus field, relates to a kind of Venturi scrubber that is used for sulfuric acid method titanium pigment calcining washing tail gas concretely.
Background technology
The workshop section of sulfuric acid method titanium pigment device calcining both at home and abroad generally adopts the rotary calciner calcining, and contains a large amount of water vapours, acid mist, solid particle in the tail gas after the calcining, and temperature is between 300～500 ℃.The calcining vent gas treatment require advance electrostatic precipitator remove acid mist before exhaust temperature reduce between 65～75 ℃ to guarantee to reach the electrostatic precipitator serviceability temperature, reduce to 65～75 ℃ equipment and generally adopt Venturi scrubber and will calcine exhaust temperature, mainly by going into inlet tube 1, collapsible tube 2, trunnion 3, enlarged tube 4, be subjected to liquid bath 5, main jet head 6 is formed, describedly advance inlet tube 1, collapsible tube 2, trunnion 3, enlarged tube 4 is in turn connected to form the main pipe, this main pipe lower end connects the described liquid bath 5 that is subjected to, this is subjected to liquid bath 5 to have gas vent 5a, and described main jet head 6 is arranged on and has following shortcoming on the described collapsible tube 2 in actual use:
Because the expansion of titanium white device capability, on the titanium white device more than 20,000 tons/year, Venturi scrubber trunnion internal diameter is all more than Φ 600mm, because the increasing of the atomizing effect of main jet head 6 and spraying coverage, the spray effect and the injection flow rate at edge have been weakened, the actual motion cooling-down effect is undesirable, often cause out the Venturi scrubber exhaust temperature to limit on the upper side, operate and careless slightlyly just easily cause the electrostatic precipitator of back to exceed operating temperature, influence the safe operation of electrostatic precipitator, even cause electrostatic precipitator to cave in and scrap.
The utility model content
The purpose of this utility model be to provide a kind of simple in structure, effect is obvious, can effectively guarantee cooling-down effect, prevent electrostatic precipitator because of exceeding operating temperature, cause electrostatic precipitator to cave in and the Venturi scrubber that is used for sulfuric acid method titanium pigment calcining washing tail gas scrapped.
The technical solution of the utility model is as follows:
A kind of Venturi scrubber that is used for sulfuric acid method titanium pigment calcining washing tail gas, comprise inlet tube, collapsible tube, trunnion, enlarged tube, be subjected to liquid bath and main jet head, described inlet tube, collapsible tube, trunnion, enlarged tube are in turn connected to form the main pipe, this main pipe lower end connects the described liquid bath that is subjected to, this is subjected to liquid bath to have gas vent, described main jet head is arranged on the described collapsible tube, and described trunnion is provided with the ring spray head.
The quantity of the described ring spray head that is provided with is 4-7.
The employing said structure owing to increased 4-7 ring spray head at the trunnion place on the basis of main jet head, can remedy because the Venturi scrubber internal diameter enlarges the influence of back main jet head to marginal portion injection flow rate and atomizing effect weakening.Guaranteed that cooling-down effect makes the electrostatic precipitator of back can obtain safe operation.
Beneficial effect: the utility model is simple in structure, effect is obvious, can effectively guarantee cooling-down effect, prevents electrostatic precipitator because of exceeding operating temperature, causes electrostatic precipitator to cave in and scraps.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
Embodiment: as shown in Figure 1: a kind of Venturi scrubber that is used for sulfuric acid method titanium pigment calcining washing tail gas, comprise inlet tube 1, collapsible tube 2, trunnion 3, enlarged tube 4, be subjected to liquid bath 5 and main jet head 6, described inlet tube 1, collapsible tube 2, trunnion 3, enlarged tube 4 are in turn connected to form the main pipe, this main pipe lower end connects the described liquid bath 5 that is subjected to, this is subjected to liquid bath 5 to have gas vent 5a, described main jet head 6 is arranged on the described collapsible tube 2, and described trunnion 3 is provided with ring spray 7.The quantity of a described ring spray that is provided with 7 is 4-7.
Claims (2)
1. one kind is used for the Venturi scrubber that sulfuric acid method titanium pigment is calcined washing tail gas, comprise inlet tube (1), collapsible tube (2), trunnion (3), enlarged tube (4), be subjected to liquid bath (5) and main jet head (6), described inlet tube (1), collapsible tube (2), trunnion (3), enlarged tube (4) are in turn connected to form the main pipe, this main pipe lower end connects the described liquid bath (5) that is subjected to, this is subjected to liquid bath (5) to have gas vent (5a), described main jet head (6) is arranged on the described collapsible tube (2), it is characterized in that: described trunnion (3) is provided with ring spray head (7).
