Description

Technical Field

[0001] The invention relates to the technical field of car wash wastewater circulation treatment, and in particular to a built-in central filter. Background Art

[0002] The recycling treatment of car wash sewage is a basic requirement for the green environmental protection of the car wash industry. There are many types of central filters for recycling car wash sewage on the market, which are usually composed of quartz sand, activated carbon, ultrafiltration membrane PVDF and other filter materials, which can filter out sludge particles in car wash sewage, sterilize, remove odor, decolorize and deodorize. The filtered water can meet the national standards for recycled water. However, during the use of these central filters, although the internal backwash device is designed to wash away the tiny sludge particles adhering to the filter membrane, due to the large number of suspended particles in car wash sewage, the surface of the PVDF ultrafiltration membrane adsorbs a large number of fine sludge particles, blocking the filtration micropores of the ultrafiltration membrane, which greatly reduces the filtration efficiency and filtration effect of the central filter. Even if the central filter has a backwash treatment designed according to the filtration pressure, it does not play a big role and requires manual continuous cleaning of the ultrafiltration membrane. Therefore, it is necessary to propose a built-in central filter to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to provide a built-in central filter to address the shortcomings of the prior art, so as to solve the problem that due to the large number of suspended particles in car wash wastewater, a large number of fine sludge particles are adsorbed on the surface of the PVDF ultrafiltration membrane, which blocks the filtration micropores of the ultrafiltration membrane, thereby greatly reducing the filtration efficiency and filtration effect of the central filter.

[0004] The present invention provides a built-in central filter, comprising: an automatic valve activated carbon filter, a clamp ultrafilter, a multi-stage filter bag, a three-way valve, an air pump, a sedimentation tank, a timed sewage cleaning electric valve and a water storage tank; a water inlet pipe is connected to a first port of the three-way valve via the timed sewage cleaning electric valve, the sedimentation tank is connected to the air pump through a pipeline, the air pump is connected to the second port of the three-way valve through a pipeline, and the third port of the three-way valve is connected to the clamp ultrafilter; the clamp ultrafilter is connected to the multi-stage filter bag, the clamp ultrafilter is connected to the automatic valve activated carbon filter through a post-filtration purified water pipeline, the automatic valve activated carbon filter is connected to the sedimentation tank through a backwash filtered water pipeline, and the automatic valve activated carbon filter is connected to the water storage tank through a recycled water pipeline.

[0005] Furthermore, the automatic valve activated carbon filter has an outer dimension of 25cm*148cm, adopts a 304 stainless steel shell, is equipped with an intelligent valve head, has a filtration capacity of 4000L / hour, and uses coconut shell activated carbon and KDF filter materials.

[0006] Furthermore, the clamp ultrafilter has an outer dimension of 20cm*60cm, a filtration capacity of 6500L / hour, is provided with a PVDF lined hand-wash ultrafiltration membrane, and adopts a 304 stainless steel casing.

[0007] Furthermore, the air pump model is YY1280W-30L.

[0008] The present invention has the following beneficial effects: The built-in central filter provided by the present invention can effectively remove suspended particles in car wash wastewater, improve filtration efficiency, and improve water quality filtration effect, so that it can be recycled or meet emission standards. The design of built-in airflow flushing and backwashing helps to automatically clean the surface of the filter material, reduce the frequency and cost of manual maintenance, and improve the continuous working efficiency of the filter. Compared with traditional filtering methods, airflow flushing is relatively energy-saving and reduces energy consumption during operation. It can remove adsorbed suspended particles in time to prevent the filter material from being blocked and failing prematurely, thereby extending the service life of the filter material and reducing replacement costs. It can operate continuously and stably to ensure the consistency of the treated water quality. BRIEF DESCRIPTION OF THE DRAWINGS
