Abstract
The utility model relates to an urotropine defoaming reaction kettle, which comprises a kettle body, an interlayer, a kettle cover and a gas phase channel arranged on the kettle body, wherein the inner wall of the kettle body is provided with a support block; a defoaming plate is arranged on the support block and adopts a perforated plate; and a layer of stainless steel mesh is arranged on the defoaming plate. The utility modle has the beneficial effects that the urotropine defoaming reaction kettle can effectively remove foams on the surface layer of mother liquor and avoids reducing the urotropine yield due to foam loss.
Description
Technical field
The utility model relates to a kind of methenamine reactor, particularly a kind of methenamine reactor with foam removal function.
Background technology
Methenamine is a kind of important chemical product, can be used as the curing agent of phenoplasts, the catalyst of aminoplast, the promoter of the vulcanization of rubber; Industrial at other, can be used as the anti-piping compound of textile production, the anticorrisive agent of food processing, diuretics pharmaceutically; After the nitrated processing a kind of important high explosives; Can be used as pesticide on the agricultural again, also can be used as the phosgene absorbent of breathing mask etc.
The industrially preparing process of methenamine is liquid phase method and vapor phase method.What suitability for industrialized production was commonly used is vapor phase method, vapor phase method is that ammonia and formaldehyde gas enter reactor together, generate methenamine with the circulating mother liquor generation condensation reaction in the still, the methenamine mother liquor that generates is through concentrated, crystallization, separation, wet methenamine after the separation obtains methenamine finished product and packing warehouse-in by pneumatic conveying drying, and isolated mother liquor returns in the reactor recycling after purified treatment again.
Ammonia and formaldehyde solid/liquid/gas reactions are more violent exothermic reactions, can form more foam on mother liquor, and foam gathers too much can be inhaled into gas phase channel, cause the methenamine yield to reduce.
The utility model content
The purpose of this utility model is that a kind of methenamine reactor with foam removal function will be provided.
In order to achieve the above object, the technical solution of the utility model is: a kind of methenamine foam removal reactor, and comprise kettle, interlayer, kettle cover, be arranged on the gas phase channel on the kettle, inner wall of kettle is provided with back-up block, on the described back-up block defoaming plate is set, described defoaming plate is a porous plate.
Further, on the described defoaming plate one deck stainless (steel) wire is set.
The beneficial effects of the utility model are: this reactor can effectively be removed the foam on mother liquor top layer, has avoided the methenamine yield that runs off and reduce because of foam.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model defoaming plate.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As depicted in figs. 1 and 2, a kind of methenamine foam removal reactor comprises kettle 1, interlayer 2, kettle cover 3, is arranged on the gas phase channel 4 on the kettle 1, and kettle 1 inwall is provided with back-up block 6, and defoaming plate 5 is set on the back-up block 6, and defoaming plate 5 is a porous plate; In order to reach better foam removal effect, on the described defoaming plate 5 one deck stainless (steel) wire is set.The foam on mother liquor surface reaches the position of defoaming plate 5, and through defoaming plate 5 obstructs, fragmentation, foam volume no longer increases, and has avoided foam to be inhaled into gas phase channel 4.
Claims (2)
1. a methenamine foam removal reactor comprises kettle, interlayer, kettle cover, is arranged on the gas phase channel on the kettle, and it is characterized in that: described inner wall of kettle is provided with back-up block, and defoaming plate is set on the back-up block, and defoaming plate is a porous plate.
2. methenamine foam removal reactor according to claim 1 is characterized in that: one deck stainless (steel) wire is set on the described defoaming plate.
