Abstract
The utility model relates to an urotropine tail gas ammonia recovery device with a gas phase method, which comprises an ammonia gas absorption tower, a condenser, an ammonia gas analyzing tower and an ammonia storage tank, wherein the condenser is connected with the top part of the ammonia gas absorption tower; the ammonia gas analyzing tower is connected with the bottom part of the ammonia gas absorption tower and the bottom part of the condenser; and the ammonia storage tank is connected with the top part of the ammonia gas analyzing tower. The urotropine tail gas ammonia recovery device with the gas phase method has the beneficial effects that the device can fully recover ammonia in urotropine tail gas and can saves raw materials so as to reduce the production cost.
Description
Technical field
The utility model relates to the methenamine production field, particularly relates to a kind of urotropine by using gas phase method tail gas ammonia recovery unit.
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.
Because methenamine has reversible and decomposition reaction, so will make that ammonia is excessive, excess of ammonia will be taken away by gas phase channel, and ammonia will run off like this, causes production cost to improve.
The utility model content
The purpose of this utility model is that a kind of device that reclaims ammonia in the methenamine tail gas will be provided.
In order to achieve the above object, the technical solution of the utility model is: a kind of urotropine by using gas phase method tail gas ammonia recovery unit comprises ammonia absorption tower, the condenser that links to each other with top, ammonia absorption tower, the ammonia Analytic Tower that links to each other with the condenser bottom, the storage ammonia jar that links to each other with ammonia Analytic Tower top bottom the ammonia absorption tower.
The beneficial effects of the utility model are: this device can fully reclaim the ammonia in the methenamine tail gas, can conservation, reduce production costs.
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 urotropine by using gas phase method tail gas ammonia recovery unit, the ammonia Analytic Tower 3 that comprises ammonia absorption tower 1, the condenser 2 that links to each other with 1 top, ammonia absorption tower, links to each other with condenser 2 bottoms with 1 bottom, ammonia absorption tower, the storage ammonia jar 4 that links to each other with ammonia Analytic Tower 3 tops.Be absorbed through ammonia absorption tower 1 from most of ammonia in the tail gas of producing methenamine, remaining tail gas contains a large amount of steam and residue ammonia, steam condenses during by condenser 2, remaining ammonia is dissolved in condensate water, remaining tail gas enters exhaust treatment system to be continued to handle, the ammoniacal liquor that comes out from ammonia absorption tower 1 and condenser 2 is resolved by ammonia Analytic Tower 3, and it is standby to be stored in storage ammonia jar 4.
Claims (1)
1. a urotropine by using gas phase method tail gas ammonia recovery unit is characterized in that: comprise ammonia absorption tower, the condenser that links to each other with top, ammonia absorption tower, the ammonia Analytic Tower that links to each other with the condenser bottom, the storage ammonia jar that links to each other with ammonia Analytic Tower top bottom the ammonia absorption tower.
