Abstract
The utility model provides a device for purifying a formaldehyde gas before the reaction of urotropine. The device comprises a purification hopper, an inlet formed in the tangential direction of the purification hopper, a filter plate arranged inside the purification hopper and positioned at the upper part of the inlet, a drain port arranged at the lower part of the purification hopper, and an outlet hopper arranged at the upper part of the purification hopper, wherein an outlet is formed at the upper part of the outlet hopper, the filter plate is a porous plate, a stainless steel filter screen is arranged on the filter plate, and the purification hopper and the outlet hopper are connected through a flange. The device has a simple structure, low manufacturing cost and a better purification effect and can meet the needs for urotropine production.
Description
Technical field
The utility model relates to the production equipment of methenamine, the purifier of formaldehyde gas before particularly a kind of methenamine reaction.
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.
Synthetic methenamine typically uses the formaldehyde gas that directly makes, and this formaldehyde gas often contains more impurity, influences the synthetic of methenamine, at present, and the formaldehyde air purifying apparatus of use, complex structure, manufacturing cost height.
The utility model content
The purpose of this utility model is the formaldehyde air purifying apparatus that a kind of simple in structure, low cost of manufacture will be provided and satisfy methenamine production demand.
In order to achieve the above object, the technical solution of the utility model is: a kind of methenamine formaldehyde air purifying apparatus, comprise the purification bucket, be arranged on the tangential inlet of purification bucket, be arranged on the interior filter of inlet top purification bucket, be arranged on the impurity discharging port that purifies the bucket bottom, the outlet bucket that is arranged on purification bucket top, outlet is arranged at described outlet bucket top, and described filter is a porous plate.
Further, on the described filter stainless steel filtering net is set.
Further, described purification bucket is connected by flange with the outlet bucket.
The utility model is simple in structure, low cost of manufacture, clean-up effect better can satisfy methenamine production demand.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, a kind of methenamine formaldehyde air purifying apparatus, comprise and purify bucket 1, be arranged on and purify the tangential inlet 6 of bucket 1, be arranged on inlet 6 tops and purify filter 5 in the bucket 1, be arranged on the impurity discharging port 7 that purifies bucket 1 bottom, be arranged on the outlet bucket 2 that purifies bucket 1 top, described outlet struggle against 2 tops have the outlet 3, described filter 5 is a porous plate; In order to obtain better clean-up effect, on the described filter 5 stainless steel filtering net is set; Easy for installation in order to make, described purification bucket 1 and outlet bucket 2 are connected by flange 4.Formaldehyde gas 6 enters and purifies bucket 1 from entering the mouth, and filters through filter plate 5, enters reactor from exporting 3, and impurity falls into and purifies bucket 1 bottom, runs up to a certain amount ofly to discharge through impurity discharging port 7.
