Abstract
The utility model discloses a kind of for paraformaldehyde production distribution showerhead, comprise the nozzle and the pipe joint that are threaded connection, described nozzle comprises nozzle body and the nozzle bore that is located at nozzle body front end, and the centre of described nozzle body is embedded with dismountable spiral runner blade.The utility model is by designs such as spiral runner, curved end and perpendicular corners, make the formalin mixed flow as much as possible of flowing through, and form the formaldehyde spraying of high speed dispersion and in the time carrying out Convective heat tranfer cooling with nitrogen, prevent the polymerization in advance of formaldehyde, finally improved the quality of paraformaldehyde.
Description
Technical field
The utility model belongs to chemical production equipment technical field, relates in particular to the formaldehyde shower nozzle for the distribution showerhead of paraformaldehyde granulation tower.
Background technology
Can there is polymerization in formalin, generate the condensate of paraformaldehyde-white powdery linear structure in long-term storage or concentration operation process.Reaction equation is as follows:
The balanced reaction generating is subject to H
+the impact of concentration is larger, the existence of micro-polar substances, the carrying out that all can accelerate polymerisation as acid, alkali and water etc.Temperature also has impact, and when temperature is low, reaction is moved to generating the direction of polymer, when temperature raises to reverse movement.When temperature is very high, depolymerization generates monomer even completely, and while especially having acid to exist, heating more easily makes it be depolymerized to gaseous formaldehyde monomer.
Prepare paraformaldehyde key and be to control the product degree of polymerization, prevent the polymerization of formaldehyde height, shorten the drying and dehydrating time, improve product yield.Formalin is by being pumped in granulation tower, and process shower nozzle sprays the paraformaldehyde of the cooling polymerization formation degree of polymerization at the uniform grading of n=11 left and right.Therefore the highly concentrated formaldehyde solution that one of them key of the quality of paraformaldehyde is to spray in granulation tower must enough disperse, and makes the degree of polymerization too high thereby avoid occurring in advance polymerization.Shower nozzle in existing process unit does not possess high degree of dispersion effect, and easily occurs dead angle, forms prepolymerization, and therefore paraformaldehyde product quality is poorer with respect to external product, and cost is high.
Summary of the invention
Goal of the invention: for problem and the defect of above-mentioned existence, the utility model provides a kind of distribution showerhead of producing for paraformaldehyde, forms mixed flow in the time that solution sprays, and the dispersion that has strengthened solution prevents the prepolymerization of formaldehyde.
Technical scheme: for achieving the above object, the utility model is by the following technical solutions: a kind of distribution showerhead of producing for paraformaldehyde, comprise the nozzle and the pipe joint that are threaded connection, described nozzle comprises nozzle body and the nozzle bore that is located at nozzle body front end, and the centre of described nozzle body is embedded with dismountable spiral runner blade.
Further improve, described nozzle bore comprises bellmouth section and straight hole section, and the outer face of the nozzle bore cambered surface that is indent.
Further, the cambered surface of the outer face of described nozzle bore is stepped cambered surface.
As preferably, the height of the ladder of described stepped cambered surface is 1～2mm.
As preferably, described nozzle is vertical setting with pipe joint, and forms round corner section.
Beneficial effect: compared with prior art, the utlity model has following advantage: by designs such as spiral runner, curved end and perpendicular corners, make the formalin mixed flow as much as possible of flowing through, and form the formaldehyde spraying of high speed dispersion and in the time carrying out Convective heat tranfer cooling with nitrogen, prevent the polymerization in advance of formaldehyde, finally improved the quality of paraformaldehyde.

Fig. 2 is the partial enlarged drawing of a-quadrant in Fig. 1.
Wherein, nozzle 1, pipe joint 2, nozzle body 3, nozzle bore 4, spiral runner blade 5, outer face 6, stepped cambered surface 7.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only be not used in restriction scope of the present utility model for the utility model is described, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the amendment of the various equivalent form of values of the present utility model.
As shown in Figure 1, a kind of distribution showerhead of producing for paraformaldehyde, is mainly used on the granulation tower in Paraformaldehyde production equipment, prevents that formalin from polymerization occurring before entering granulation tower.It is mainly made up of nozzle and pipe joint, and wherein nozzle comprises nozzle body and the nozzle bore that is located at body front end, and nozzle body is rectangular shaped, and tail end is connected with pipe joint screw thread, and nozzle body center is annular channel, is embedded spiral runner blade in this passage; Nozzle bore comprises the straight hole section of conical section and aperture simultaneously, thereby makes the formalin of flowing through form High Rotation Speed dispersing morphology, ejects and forms the vaporific of high dispersive, and spiral runner blade employing is embedded mode can be for convenience detach.Simultaneously, we further improve nozzle bore, the outer face of nozzle bore is designed to the stepped cambered surface of indent, the height of ladder is 1mm, and ladder designs for fillet, make formalin from nozzle bore at a high speed ejection form oblique fluffy shape along curved end, the nitrogen formation strong convection heat exchange that when favourable dispersion and granulation tower top enters.As preferred version, curved end is designed to step-likely can effectively improve atomizing effect, thereby to carry out heat exchange cooling with nitrogen.In addition, nozzle body adopts quarter bend dihedral to become, make the formalin entering from pipe joint form around the corner mixed flow, it while avoiding formalin to enter, is laminar flow, because when rectilinear duct length reaches a timing, the liquid of flowing through can form relatively static upper, thereby relative mobile tailing off improved the polymerization risk of formaldehyde.
