Description
Technical field
The present invention relates to a kind of foul smell method of converting.
Background technique
Currently, stench when extracting excreta from lavatory using ambulance car (vacuum cart) becomes problem.In general, with defending
It when raw vehicle suction excreta, will be depressurized in fecaluria tank using vacuum pump, from the hose of the fecaluria tank is connected to by excreta
It is drawn into fecaluria tank.In addition, will be pressurizeed in fecaluria tank using vacuum pump, when discharge excreta from being connected to the fecaluria
Excreta is expelled to outside fecaluria tank by the hose of tank.
When aspirating or above-mentioned excreta being discharged, the air containing foul smelling in fecaluria tank can be expelled to outside, to behaviour
Work person and neighbouring resident bring offending feeling, thus become problem.
Especially when aspirating excreta, need to dislike from the top of fecaluria tank using containing in vacuum pump suction fecaluria tank
Smelly air and depressurized, be exhausted via vacuum pump to outside, therefore, be easy to produce above-mentioned stench.In exhaust, benefit
It is deodorized with the deodorizer (filter) for the exhaust outlet for being configured at fecaluria tank, still, reduces insufficient ask there are stench
Topic.
As the means for reducing above-mentioned stench, a kind of deodorization device of vacuum cart is proposed, is set to making to be situated between from vacuum
When the fecaluria tank of vehicle leads to the vacuum pump operating of the piping system of atmosphere and carries out the pump drainage of fecaluria, in the circulation line of vacuum pump
On have the moisturizing slot that storage is mixed into the recirculated water of deodorant, and propose and use caustic soda, sodium hypochlorite as deodorant
Smelly eliminating method (referring for example to patent document 1).
But there are the following problems: the stench of the excretas such as fecaluria is difficult to completely disappear, and uses deodorant as described above
Method cannot be by the abundant smelly eliminating of stench beastly.
Also, in above-mentioned smelly eliminating method, it is necessary to be mixed into the moisturizing slot or circulation of the recirculated water of deodorant with water storage
The recycle unit of water there are problems that needing large-scale device.
Therefore, it is intended that exploitation can be easily reduced and be generated when being aspirated using ambulance car from lavatory and excreta being discharged
The means of stench beastly.
