Description
Technical field
The present invention relates to the environmental protection field, particularly a kind of recirculated water filters automatic sewage discharging device.
Technical background
In general, the recirculated cooling water of applications such as power plant, chemical industry, oil, steel-making, steamer, warship derives from rivers, lake, ocean, underground water, replenishes and recycles.Except that underground water, all there is the dirt of different slag things and circulation at other water source, all will enter condenser, so condenser is stopped up, the maintenance of hydrologic cycle cooling system is brought a lot of troubles.
In addition, the light water circulating cooling system will also have many tiny dirts and enter cooling body by after the multistage filtering.Such as: the condenser of power plant water circulation system by forming by the brass tube of a lot of internal diameter 16mm-18mm, water inlet pipe before the condenser, will enter condenser as the dirt that does not carry out filtration cycle water, and obstruction cooler pipeline, cooling circulating water is obstructed, different one-tenth degree ground has influenced hot conversion, so improved cost of electricity-generating; Also want frequent cleaning cooling system, increased maintenance cost.
Summary of the invention
The object of the present invention is to provide a kind of recirculated water to filter automatic sewage discharging device, it can guarantee the cleannes of cooling circulating water, improves heat exchange efficiency, reduces maintenance cost.
Technical scheme of the present invention is:
A kind of recirculated water filters automatic sewage discharging device, it comprises: water inlet connects tubular compensator, upper cover, capping down, conical screen, filter mechanism body, electrically operated valve, delivery port tube connector, blowdown delivery port, blow-off pipe, and it is characterized in that: the filter mechanism body is arranged in the recirculated water circulation line; Filter mechanism body inlet end is provided with water inlet and connects tubular compensator, and is connected with following capping; Be provided with conical screen in the filter mechanism body; The upper end of conical screen is connected with blow-off pipe; Blow-off pipe is connected with blowdown motor-driven valve, blowdown delivery port after drawing the filter mechanism body; Filter mechanism body upper end is provided with upper cover, delivery port tube connector; The delivery port tube connector is connected with condenser in the circulation line.
Wherein, the flow area of described conical screen is than the big 2-3 of flow area times of caliber.
Described blowdown electrically operated valve adopts control automatically, when increasing attached to the dirt on the conical screen, the blowdown electrically operated valve will be opened automatically, and sewage reaches and passes through blow-off pipe attached to the dirt on the conical screen, flow out through the blowdown effluent pipe mouth, realize the circulation of a sewage discharge.
The invention has the advantages that: the present invention is simple in structure, low cost of manufacture, and operating cost is low; It is little to take installing space; Runnability is reliable, has guaranteed the cleannes of cooling water, has prolonged the cleaning frequency of heat exchanger tube, has improved heat exchange efficiency, has reduced maintenance cost.
Description of drawings
Fig. 1 filters the automatic sewage discharging device structural representation for recirculated water of the present invention.
Fig. 2 filters the automatic sewage discharging device workflow diagram for recirculated water of the present invention.
Number in the figure is:
1, water inlet connects tubular compensator; 2, capping down; 3, conical screen; 4, filter mechanism body; 5, upper cover; 6, delivery port tube connector; 7, electrically operated valve; 8, blowdown effluent pipe mouth; 9, blow-off pipe; 10, condenser; 11, cooling system.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.As shown in Figure 1, recirculated water of the present invention filters automatic sewage discharging device, and it comprises: water inlet connects tubular compensator 1, capping 2 down, conical screen 3, filter mechanism body 4, upper cover 5, delivery port tube connector 6, electrically operated valve 7, blowdown effluent pipe mouth 8, blow-off pipe 9, condenser 10, cooling system 11.
Wherein, filter mechanism body 4 is arranged in the recirculated water circulation line; Filter mechanism body 4 inlet end are provided with water inlet and connect tubular compensator 1, and are connected with following capping 2; Be provided with conical screen 3 in the filter mechanism body 4; The upper end of conical screen 3 is connected with blow-off pipe 9; Blow-off pipe 9 is drawn filter mechanism body 4 backs and is connected with electrically operated valve 7, blowdown effluent pipe mouth 8; Filter mechanism body 4 upper ends are provided with upper cover 5, delivery port tube connector 6; Delivery port tube connector 6 is connected with condenser 10 in the circulation line.
The course of work that recirculated water of the present invention filters automatic sewage discharging device is:
As shown in Figure 2, the recirculated water that prepare to filter connects the conical screens 3 that tubular compensator 1 and following capping 2 enter into settings in the filter mechanism body 4 by water inlet; Filter by conical screen 3; Water after the filtration enters again and filters in the body 4; Enter delivery port by upper cover 5, delivery port tube connector 6 again; Then, enter condenser 10 in by circulation line the water handled well and carry out the water circulation in the cooling system 11.
Because the flow area of conical screen 3 of the present invention than the big 2-3 of flow area times of caliber, has increased the filter area of filter screen, thus unimpeded in filter process, be not easy to stop up filter screen, guarantee filter quality.In the blowdown process, conical screen 3 also has characteristics, and promptly dirt is not easy to stick on the filter surface, has guaranteed the cleannes in the blowdown process each time.
After filtering a period of time, can increase attached to the dirt on the conical screen 3, at this moment, blowdown electrically operated valve 7 will be opened automatically, sewage reaches attached to the dirt on the conical screen 3 by blow-off pipe 9, through 8 outflows of blowdown effluent pipe mouth, the circulation of a sewage discharge of realization.
After the blowdown circulation finished, blowdown electrically operated valve 7 was closed automatically.
The recirculated water of preparing to filter filters again, can carry out the timing blowdown again then.Again and again circulation goes on, and has so just formed the automatic cyclic process of recirculated water filtration, blowdown.
