Abstract
A formaldehyde calcar fast cooling section comprises a calcar, a row tube and an upper tube board and a lower tube board, wherein, the upper tube board is of the shape of paraboloid, an upper gas room is ring arranged on the upper end of the calcar and the edge of the upper tube board, the upper gas room is connected with an upper tube board and the outer wall of the calcar and is communicated with the shell layer of the calcar wall. A steam gas outlet opening is arranged on the upper gas room. When the formaldehyde calcar fast cooling section is in use, the formaldehyde of hot gas generated by the reaction of the carbinol enters the calcar row tube through the upper portion of the calcar and is fast cooled by the cooling water entering the calcar to become the liquid formaldehyde. Simultaneously, the cooling water is heated by the formaldehyde gas with high temperature and become the water steam and discharged through the gas outlet opening. The temperature reducing of the formaldehyde and the temperature rising of the cooling water are both of fast speed, thereby improving the calcar efficiency. The utility model has the characteristics reasonable design, simple structure, easy manufacturing, great using effect, smooth gas discharge and improved working efficiency of the reactor.
Description
(1) technical field
The utility model relates to a kind of oxidized still quench zone, particularly a kind of oxidation of formaldehyde stove quench zone.
(2) background technology
The upper tubesheet of oxidized still has two kinds in the Formaldehyde Production at present: dull and stereotyped and last bulb flat.The oxidized still of plate shaped upper tubesheet, the tubulation in the oxidized still damages easily, and in the work, oxidized still top often produces the 5-6cm steam chest, and steam discharge has some setbacks, and having a strong impact on reactor is the oxidized still cooling; Last spherical tubesheet is owing to the tube sheet shape, and tubulation quantity is few in the oxidized still, between reaction chamber top and the tube sheet dead angle is arranged, and influences reaction chamber work.
(3) summary of the invention
At the deficiencies in the prior art, the utility model provide a kind of reasonable in design, simple in structure, easy to manufacture, result of use is good, steam discharge is smooth and easy, can improve the oxidation of formaldehyde stove quench zone of reactor working efficiency.
A kind of oxidation of formaldehyde stove quench zone, form by oxidized still, tubulation and upper and lower tube sheet, upper tubesheet is a parabolic shape, adorns steam chest at upper tubesheet edge and oxidized still top ring, and last steam chest is connected with upper tubesheet and oxidized still outer wall also and the shell of oxidation furnace wall is communicated with.
Last steam chest is provided with the steam steam outlet.
Upper tubesheet in the utility model in use, the formaldehyde that methyl alcohol reaction generates hot gas enters the oxidized still tubulation from oxidized still top, the water coolant that is entered oxidized still cools off fast, becomes formaldehyde liquid; Simultaneously, water coolant is discharged from the steam steam outlet of last steam chest by very high formaldehyde vapour heating the becoming water vapor of temperature.Because the speed of formaldehyde cooling and water coolant intensification is all very fast, makes formaldehyde become liquid and water coolant is very fast by the speed that liquid becomes gas, thereby improved the efficient of oxidized still by gas.
The utlity model has reasonable in design, simple in structure, easy to manufacture, result of use is good, steam discharge is smooth and easy, can improve the characteristics of reactor working efficiency.
(4) description of drawings
Fig. 1 is a section of structure of the present utility model.
Wherein, 1, oxidized still, 2, upper tubesheet, 3, tubulation, 4, go up steam chest, 5, the steam steam outlet, 6, cooling water intake.
(5) embodiment
Embodiment: structure of the present utility model as shown in Figure 1.Be made up of oxidized still 1, tubulation 3 and upper and lower tube sheet, upper tubesheet 2 is a parabolic shape, adorns steam chest 4 at upper tubesheet 2 edges and oxidized still 1 top ring, and the outer wall of last steam chest 4 and upper tubesheet 2 and oxidized still 1 is connected also and the shell of oxidation furnace wall is communicated with.Last steam chest 4 is provided with steam steam outlet 5.
Claims (2)
1, a kind of oxidation of formaldehyde stove quench zone, be made up of oxidized still, tubulation and upper and lower tube sheet, it is characterized in that, upper tubesheet is a parabolic shape, adorn steam chest at upper tubesheet edge and oxidized still top ring, last steam chest is connected with upper tubesheet and oxidized still outer wall also and the shell of oxidation furnace wall is communicated with.
2, oxidation of formaldehyde stove quench zone as claimed in claim 1 is characterized in that last steam chest is provided with the steam steam outlet.
