Description

The urea water of tool waste water filtering function is produced equipment

Technical field

The utility model relates to a kind of urea water and produces equipment, and the urea water of espespecially a kind of tool waste water filtering and recovery function is produced equipment.

Background technology

Press, urea water (being called again automobile-used urea water) makes an addition to selective media reductive system (the Selective Catalytic Reduction of diesel motor conventionally, SCR) in as media reductive agent, for example, in order to reduce the content of noxious material in the waste gas of this diesel motor discharge or gas (nitrogen oxide), general urea water is produced equipment 1, refer to shown in Fig. 1, it is conventionally by a mixing apparatus 12, a heater 11 and a purifier apparatus 13 form, wherein this mixing apparatus 12 is connected with this heater 11 and purifier apparatus 13 by pipeline respectively, this mixing apparatus 12 is generally a bucket groove, the process of its production urea water is in this barrel of groove, to inject processing procedure water, again technical grade urea (urea) is dropped in this barrel of groove, after uniform temperature, obtain semi-finished product urea water simultaneously and by stirring and heater 11 circulating-heatings, this semi-finished product urea water being transported to purifier apparatus 13 carries out after purifying removal impurity again, can be obtained by the outlet of purifier apparatus 13 final finished product is automobile-used urea water A1.

Refer to shown in Fig. 1, this purifier apparatus 13 is comprised of ion exchange resin conventionally, its purification efficiency can be along with service time or number of times and is weakened (being that ionic adsorption reaches capacity), therefore this urea water is produced equipment 1 regenerating unit 14 can be set conventionally, in order to the ion exchange resin of regenerating in this purifier apparatus 13, this regenerating unit 14 is connected with purifier apparatus 13, this regenerating unit 14 is generally equipped with respectively acid by several, alkali medicament example hydrochloric acid (HCL), the bucket groove of sodium hydroxid (NaOH) and water forms, about being those skilled in the art, the thin portion structure of this regenerating unit 14 and operating principle know, therefore repeat no more, shown in Fig. 2, though this regenerating unit 14 can reach the effect of the ion exchange resin of this purifier apparatus 13 of regeneration, but finally can produce and contain acid, the waste water A 2 of alkali medicament and urea, waste water A 2 will be to environment as being discharged into the external world, for example urea can make biochemical oxygen demand (BOD) (the Biochemical Oxygen Demand in water, BOD) and COD (Chemical Oxygen Demand, COD) numerical value rises, cause rich oxidative phenomena, thus, making urea water produce equipment 1 production urea water has a greatly reduced quality in order to reduce air-polluting environmental protection kindness, hereat, how for above-mentioned disappearance, to be improved, be the technical difficulties place that the present utility model people institute wish solves.

Utility model content

Because existing urea water is produced equipment, because its regenerating unit can produce contaminated wastewater environment, so the utility model object is that the urea water that develops a kind of tool waste water filtering function produces equipment, can and reclaim waste water filtering.

For reaching above object, main technical schemes of the present utility model is:

The urea water of tool waste water filtering function is produced an equipment, and it comprises: a urea water is produced device; A regenerating unit, this regenerating unit is connected with urea water production equipment, and this regenerating unit is provided with a waste water discharge opening again; A filtering recovering device, in this filtering recovering device, include a waste water temporary storage barrel and a filter, wherein this waste water temporary storage barrel is connected with waste water discharge opening and the filter of this regenerating unit respectively, and this filter is also connected with urea water production device again.

The beneficial effects of the utility model are: the utility model is by arranging this filtering recovering device, and this urea water can be produced to device, complete the waste water filtering that produces after regeneration for urea-containing recycle-water only, make to reach the object of waste water recycling and wastewater zero discharge, and then make the utility model can reach the effect that promotes environment protecting and reduce production costs.
