Abstract
The invention relates to a preparation method of a solid ammonia storage module. The preparation method is characterized by comprising the following specific steps: firstly, drying anhydrous strontium chloride at the constant temperature of 260DEG C for 1.5 hours, and discharging all water and ethanol; requiring the main content of the anhydrous strontium chloride before drying to be 99 to 100 percent; secondly, directly putting the dried anhydrous strontium chloride into a closed pressure container, and sealing a charging opening; carrying out vacuumizing treatment on the pressure container at the vacuum degree of 0.09MPa, and exhausting air; thirdly, introducing ammonia at the pressure of 0.5 to 0.8MPa until the anhydrous strontium chloride is absorbed to be saturated; fourthly, taking out the anhydrous strontium chloride subjected to ammonia adsorption from the pressure container, guaranteeing that the temperature is 10DEG C or lower, feeding to a die without sealing, controlling the temperature to prevent the anhydrous strontium chloride subjected to ammonia adsorption from starting releasing caused by high temperature, and compressing into a specified shape by using the die; determining the shape of the die according to the shape of an ammonia storage tank, wherein the shape can be circular, elliptical or square. An ammonia storage material adsorbs the ammonia to the maximum extent when the ammonia storage tank reaches a certain volume, the storage amount of the ammonia is increased, the endurance mileage is increased, and the preparation method is enabled to be more suitable for industrialization.
Description
Technical field
The present invention relates to a kind of solid stores up the preparation method of ammonia module, belong to vehicle maintenance service systems technology field.
Background technology
With the progress of economic society, auto industry is fast-developing, the increasing number of automobile, what vehicle exhaust was caused
Environmental pollution is also increasingly serious.Therefore the purifying problem of vehicle exhaust, is increasingly subject to the attention of people.
Vehicle maintenance service system is to store ammonia and to discharge when needed with solid particulate matter, with catalyst reaction after go
Except NOx hazardous materials, the purpose of cleaning of off-gas has been reached.The method is safe and reliable, low cost, course continuation mileage are long.
But during solid ammonia storage tank ammoniated, volumetric expansion after solid ammonia storage material absorption ammonia, and ammonia storage tank is held
Product is limited, so only filling 60% ammonia of theoretical value, continuing to fill needs the more time, can not completely adsorb ammonia, therefore
Current solid ammonia storage tank can not meet VMT Vehicle-Miles of Travel demand.
In sum, solid ammonia storage tank ammoniated amount is increased, it is that current those skilled in the art are badly in need of solving to improve storage ammonia ability
Problem.
The content of the invention
It is an object of the invention to provide a kind of solid storage ammonia module and preparation method thereof, it makes ammonia-storing material hold in ammonia storage tank
Absorption ammonia is maximized in product is certain, increases ammonia storage capacity, improve course continuation mileage so as to be more suitable for industrialization.
The technical scheme is that what is be achieved in that：A kind of solid stores up the preparation method of ammonia module, it is characterised in that its
Preparation method, comprises the following steps that：1st, anhydrous strontium chloride is dried 1.5 hours under 260 DEG C of constant temperature, discharges whole water and second
Alcohol；It is required that the main content of anhydrous strontium chloride before drying is in 99 %-100%；2nd, directly put into after anhydrous strontium chloride drying closed
In pressure vessel, charge door is sealed；By the process of pressure vessel evacuation, vacuum 0.09MPa, air-out；3rd, in 0.5-
Ammonia is passed through under 0.8MPa, till anhydrous strontium chloride adsorption saturation；4th, absorption ammonia afterchlorinate strontium is taken out from pressure vessel,
Ensure that temperature below 10 DEG C, is delivered at mould, without the need for sealing, it is to prevent temperature height from causing to adsorb the chlorination of ammonia to control temperature
Strontium starts release, with dies compress established practice setting shape；Can be circular, oval or square depending on according to ammonia storage tank shape.
The positive effect of the present invention is that absorption ammonia is maximized in ammonia storage tank volume is certain, increases ammonia storage capacity, is carried
High course continuation mileage so as to be more suitable for industrialization.Original technology is first will to carry out ammoniated after in anhydrous strontium chloride fill ammonia storage tank,
Due to volumetric expansion after strontium chloride absorption ammonia, the whole ammonia storage tank of distension within 10 hours, and now ammonia filling weight is in 50-
Between 60%, the present invention is to allow anhydrous strontium chloride to adsorb volume after ammonia infinitely to expand, and is adsorbed completely to ammonia, is being incited somebody to action with mould
It is compressed into regulation character, is putting in ammonia storage tank, and ammonia storage tank storage ammonia amount can so doubled, and storage ammonia ability improves one
Times, substantially increase course continuation mileage.
Specific embodiment
With reference to embodiment, the present invention will be further described：A kind of solid stores up the preparation method of ammonia module, its feature
It is its preparation method, comprises the following steps that：1st, anhydrous strontium chloride is dried 1.5 hours under 260 DEG C of constant temperature, discharges whole water
And ethanol；It is required that the main content of anhydrous strontium chloride before drying is in 99 %-100%；2nd, directly put into after anhydrous strontium chloride drying close
In the pressure vessel for closing, charge door is sealed；By the process of pressure vessel evacuation, vacuum 0.09MPa, air-out；3rd, exist
Ammonia is passed through under 0.5-0.8MPa, till anhydrous strontium chloride adsorption saturation；4th, will absorption ammonia afterchlorinate strontium from pressure vessel
Take out, it is ensured that temperature is delivered at mould below 10 DEG C, without the need for sealing, control temperature is to prevent temperature height from causing to adsorb ammonia
Strontium chloride start release, with dies compress established practice shape shape；Depending on according to ammonia storage tank shape, can for circular, oval or
It is square.
