Abstract
The utility model discloses a solid urea crushing and generating device, which is invented for solving the problem that the prior art is not convenient to use. The solid urea crushing and generating device comprises a shell, a urea storage box, more than one controlled valves, an exhaust device and a control device, wherein more than one controlled valves are arranged at the peripheral direction of the upper part of the urea storage box; and the control device is used for controlling a drive shaft to rotate and the controlled valves to open according the inner pressure of the shell and the preprogram, or controlling the drive shaft to stop rotating and the controlled valves to close according to the inner pressure of the shell and the preprogram. The utility model has the following advantages that: 1, the storage box and a crushing and heating device are designed together, so the space is saved; 2, the solid urea crushing and generating device can more thoroughly crush the solid urea, so a gas circuit is effectively prevented from being blocked; and 3, an electromechanical accelerating device is not needed to rotate all the time, so the service life of a motor is prolonged.
Description
Technical field
The utility model relates to a kind of solid urea and pulverizes generating means, and particularly a kind of solid urea that is applied in the diesel-oil vehicle selective catalytic reduction catalyst is pulverized pyrolysis apparatus.
Background technique
Document number EP1338562A1 open day was that the European patent on August 27th, 2003 has been described a kind of method and apparatus that produces ammonia.The urea granules of wherein laying in a storage tank is sent into by pressurized air stream in the reactor that produces ammonia, solid urea is changed into the mixed gas of ammonia and isocyanic acid by pyrolysis rapidly.And then this mixed gas hydrolysis ammonification and carbon dioxide under the effect of water vapour.The solid urea particle provides the permanent compression air source with the prerequisite of pressurized air support, promptly needs an air compressor inflation, and the method expense under concrete condition is too big, is not suitable for diesel-oil vehicle and uses.
The model utility content
For overcoming above-mentioned defective, the purpose of this utility model is to overcome above-mentioned deficiency, proposes a kind of space of having saved, and has reduced the cost solid urea and has pulverized generating means.
For achieving the above object, solid urea of the present utility model is pulverized generating means, comprising:
Hermetic seal in the shell, described shell is provided with heating equipment in described housing exterior, is provided with thermal insulation layer outside described heating equipment;
The urea material storing box is arranged in the described shell by live axle is rotatable, is provided with spring in described urea material storing box bottom, is provided with piston on described spring; Be circumferentially with more than one controlled valve on described urea material storing box top,
Venting gas appliance is arranged on the bottom of described shell;
Control gear is used for controlling described live axle rotation and controlled valve open according to the pressure in the shell according to preset program; Or control described live axle according to the pressure in the shell according to preset program and stop the rotation and controlled valve closing.
Particularly, described inner walls and/or cabinet exterior are coated with thermal insulating material.
Particularly, described live axle is connected with electric motor drive outside shell.
Particularly, outside described shell, be provided with the temperature transducer that is electrically connected with control gear; Temperature in the shell that described control gear records according to temperature transducer according to the startup of preset program control Electric heating appliance with close.
Compared with the prior art the utility model has following advantage:
1, the utility model designs material storing box and is in the same place with the pulverizing heating equipment, has saved the space.
What 2, the utility model can be pulverized solid urea is more thorough, has effectively prevented the gas circuit obstruction.
3, the motor type accelerating unit need not to rotate always, has prolonged the working life of motor.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment:
Below in conjunction with Fig. 1 the utility model is further described.
As shown in Figure 1, shell 6 is an airtight housing, and it should select the material that can prevent the urea corrosion for use, and can bear certain pressure (20 barometric pressure), can select stainless steel material for use.Outside heats with resistance wire, by temperature transducer and control gear temperature is controlled between 150 ℃-160 ℃.Heating equipment outer wrap asbestos are with insulation.
Urea material storing box 7, by live axle 3 rotatable being arranged in the described shell 6, the bottom in described urea material storing box 6 is provided with spring 2, is provided with piston 8 on described spring; Be circumferentially with more than one controlled valve 1 on described urea material storing box top, valve can open or close under the control of control gear.Valve can adopt stainless steel material.
Venting gas appliance is made up of outlet pipe 4 and outlet valve 5.Be arranged on outer casing underpart with exhaust as required.
During use, solid urea particle is added material storing box 7,, can guarantee that the highest plane of solid urea remains on and the minor valve isoplanar by the quality of design piston and the progress coefficient of spring.When the diesel-oil vehicle engine operation, motor begins to rotate, because the effect of centripetal force, makes the solid urea particle material storing box 7 that flies out, and bump back and forth between wall and material storing box 7 outer walls in the enclosure plays the effect of heating pulverizing.At this moment urea pyrolysis produces ammonia and isocyanic acid.The setting value upper limit time-control apparatus that the pressure of gas is higher than in case is closed valve 1, and controlling and driving axle 3 stops the rotation simultaneously.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away from according to any simple modification, equivalent variations and the remodeling that technical spirit of the present utility model is done above example, still belongs to the protection domain of technical solutions of the utility model.
