Description

The liquid case of band ventilation system
The present invention relates to a kind of liquid case, relate in particular to a kind of liquid that is suitable for to freeze, and be furnished with the liquid case of integrated form heating element for this reason.More particularly, the present invention relates to a kind of ventilation system of being furnished with the liquid case of said band integrated form heating element.The present invention is particularly useful for can on heat-engined vehicle, being used to pollute the urea groups reducing agent case of control.
For meeting pollution criterion, motor vehicle must be connected with the pollution control device that becomes complicated day by day, and the principles of chemistry of polluting control require to add catalyzer or oxygenant or reducing agent, particularly in gas exhaust piping, to realize polluting control.
The pollution control of relevant diesel engine road vehicle requires MANUFACTURER on vent systems, to be equipped with catalytic exhaust-gas converter in the standard, adopt ammonia to reduce nitrogen oxide.Yet,, pollute control through realizing that with the urea that is dissolved in the water such as 33% ratio urea only just changes ammonia into through thermal hydrolysis when it is used in vent systems because ammonia is a kind of poisonous goods.This process is commonly called " SCR " (selective catalytic reduction, Selective Catalytic Reduction).
The demand that the proportioning of urea must cause according to the nitrogen oxide ventilation that motor produced is adjusted.For this reason, urea is stored in a case, is pressurizeed by pump; And send by magnetic injectors; Cooperate the running of motor, cooperate the nitrogen oxide ventilation condition through gas exhaust piping then, pump and sparger carry out proportioning to the amount of taking from case and delivering to the ammonia of gas exhaust piping.
In this type of pollution control facility, must provide heating equipment to solve the problem that urea or other reducing agents freeze, when can being lower than-11 ℃ in temperature, these problems occur.The existence of heating equipment itself can produce the problem of the exhaust of reducing agent case or " breathing ", so that a certain amount of thawing reducing agent is discharged from, and still preserves a large amount of reducing agents that solidify in the casing.
Proposed some solutions and be furnished with the reducing agent case ventilated port of heating element in order to formation, this heating element design is used for melting reducing agent.Particularly, the solution that patent document WO2008-080694 A1 is disclosed is in the reducing agent case, to place one to add thermopipette, realizes the discharge of liquid through this pipe.The heating of pipe can make its peripheral skim reducing agent melt, can make like this in the volume of the thawing reducing agent of the bottom half at main heating element place and casing still the flow surface freezed of maintenance communicate with volume of air between this casing roof.
Yet this solution also is not suitable for the reducing agent case of form of ownership, particularly in suction pipe and casing under the not contacted situation of the air body above the reducing agent liquid level.When the roof of casing is to have segmentation form, the suction pipe in below district and top district to pass the below district and inner air body when only being positioned at below this wall highest region, this situation can appear.Under this configuration, even suction pipe is a heating pipe, the air that is limited in the casing can not communicate with the discharge zone of reducing agent.
For the liquid case that other liquid that possibly freeze are housed, for example same problem can appear in the washing apparatus liquid case that keeps out the wind on the automobile.
The present invention aims to provide the solution to the problems referred to above, and especially being intended to for this reason, the liquid case of the type of place consideration provides a kind of ventilation solution applicable to all liquid box shapes.
For this reason; The present invention relates to a kind of liquid case on the heat-engined vehicle that can be used in order to reduce pollution, for example, can be used for polluting on the heat-engined vehicle reduction especially for being used for the reducing agent case of urea groups reducing agent; Be furnished with integrated form heating element and ventilation system on the liquid case; This ventilation system is used for that air can be got into and replaces in the heating element district liquid that melted and discharged from the liquid case by said heating element, and said liquid case is characterised in that, ventilation system comprises conduit and hydrophobic; This conduit is connected to the zone of heating element in the part that is full of air of liquid case outside or liquid case inside; This hydrophobic, i.e. impermeable the and air permeable of liquid, thus be placed in said conduit starting point place near heating element.
This hydrophobic especially is made up of so-called " breathing freely " film.This hydrophobic starting point place that is placed in conduit; Conduit can be flexible pipe or rigid pipe; This conduit is connected to the zone of heating element that to be positioned at the liquid case outside and at an upper portion thereof or the position of bottom, is connected to perhaps that to be positioned at the liquid case inner and in the position of the liquid upper box part that is higher than liquid level.
In a kind of simple mode of execution, this hydrophobic, especially adopt form membrane, directly be fixed on the end such as the conduit of flexible pipe or rigid pipe through stickup, mode molded, fixing or welding (especially being ultrasonic welding).
According to another kind of possibility; This hydrophobic; Especially adopt form membrane; Through paste, mode molded, fixing or welding (especially being ultrasonic welding) is fixed on and is positioned at such as on the adaptive middleware on the end of the conduit of flexible pipe or rigid pipe, the cross section of this middleware is bigger than the cross section of conduit.When " breathing freely " function needs relatively large film, be fit to adopt this alternative.
Under any circumstance, hydrophobic is immersed near the heating element, can prevent that thus the liquid that melts from flowing out through conduit, particularly flows to the top of casing, can force to make fluid by the pump suction of installing thus.Yet even under the situation that liquid freezes, heating element also possibly aspirate the liquid of some thawings because air can through conduit or hydrophobic from the casing outside or inner upper be admitted to the zone of said heating element.It should be understood that this conduit and liquid suction flexible pipe is isolated, a kind of solution that adapts to all case geometrical shapies (especially aspirating flexible pipe does not contact with the inner air body) can be provided thus.
Through following explanation, and, can understand the present invention better with reference to the sketch of enclosing of the some kinds of mode of executions that this liquid case that has a ventilation system is shown as an example:
Fig. 1 is the sectional arrangement drawing according to first kind of mode of execution of the reducing agent case that has a ventilation system of the present invention;
