Abstract
The utility model discloses a backflow preventing structure of a tower body for water treatment. The backflow preventing structure comprises the tower body, a liquid inlet arranged at the top of the tower body, a liquid outlet arranged at the bottom of the tower body, an air inlet arranged at the bottom of the tower body, an air outlet arranged at the top of the tower body, and a water seal which is arranged at the bottom of the tower body and is used for sealing the liquid outlet, wherein the air inlet is connected with an air outlet of an air blower through an air inlet pipeline; and the air inlet pipeline is provided with a backflow preventing structure for preventing water in the tower body from flowing back to the air blower through the air inlet pipeline. According to the utility model, the air inlet pipeline is provided with the backflow preventing structure for preventing the water in the tower body from flowing back to the air blower through the air inlet pipeline, so that when the water at the bottom of the tower body flows back to the tower, the water does not enter air supply equipment to burn out a motor, so that the service life of the equipment is prolonged, the operation is safe and reliable and the efficiency is high.
Description
Technical field
The utility model relates to a kind of water treating equipment, particularly a kind of new type of safe efficient stripping (aeration) tower.
Background technology
In water treatment system, stripping tower is mainly used in the CO that removes in anhydrating
2Or ammonia nitrogen gas, gas is sent into by gas blower from the tower body bottom, contains CO
2Or the water of ammonia nitrogen gas gets into from the top of tower body, drench down through distribution apparatus, gas on the inner-tower filling material surface with after water fully contacts, together with the CO of effusion
2Or ammonia nitrogen gas discharges from the top of stripping tower together, and water fully contacts effusion CO at filling surface with air
2Or enter water storage tank from the bottom behind the ammonia nitrogen gas, thereby reach CO
2Or the desorb of ammonia nitrogen gas.Gas is then sent in the tower by aerator in aeration tower, is mainly used in the dissolved oxygen that increases in the water.
Water outlet enters water storage tank to water from the tower body bottom; Water storage tank operated by rotary motion level control valve or surplus valve, and when level control valve in the water tank when malfunctioning or water tank overflow valve is inoperative, the water seal of tower body bottom just cannot stop the upwards retrograde of water; Water is poured in down a chimney get into air blast (aeration) machine; Cause blower fan water inlet motor to burn out, cause safety-problems, reduce the efficient of operation.
The utility model content
The utility model technical problem to be solved just provides the anti-return structure of a kind of water treatment with tower body, improves through simple structure, makes the stripping tower operating safety stable, and efficient is high.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of water treatment is with the anti-return structure of tower body; Comprise tower body, be arranged on the fluid inlet at tower body top and be arranged on tower body bottom liquid outlet, be arranged on the inlet mouth of tower body bottom and be arranged on the tower body top the air outlet, be arranged on the water seal of tower body closed bottom liquid outlet; Said inlet mouth is characterized in that through the air outlet of admission passage connection gas blower: said admission passage is provided with and prevents that water is through the retrograde anti-return structure to gas blower of admission passage in the tower body.
As preferably, said anti-return structure is that admission passage is designed to be inverted U type pipe, and peristome one end of said inverted U type pipe connects inlet mouth, and the other end is connected with blower outlet.
As preferably, the top of said inverted U type pipe admission passage is higher than the tower body top.
As preferably, be connected with the inlet mouth below of side of said inverted U type pipe admission passage is provided with water discharge valve, and said water discharge valve is the pressure valve of a low pressure control.
As preferably, said anti-return structure is the vacuum breaker that is provided with on the admission passage.
As preferably, said tower body is stripping tower or aeration tower tower body.
The utility model improves through simple structure, and promptly admission passage is provided with and prevents that water is through the retrograde anti-return structure to gas blower of admission passage in the tower body.The anti-return structure can be for being inverted U type pipe at admission passage; It perhaps is the vacuum breaker that is provided with on the admission passage; Thereby when making water in tower body bottom be back in the tower, can not get into air feed equipment and cause motor to burn out, prolonged the work-ing life of equipment; Make safe and reliable to operationly, efficient is high.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1; Be the embodiment of a kind of water treatment of the utility model with the anti-return structure of tower body; Comprise tower body 1, be arranged on the fluid inlet 2 at tower body top and be arranged on tower body bottom liquid outlet 3, be arranged on the inlet mouth 4 of tower body bottom and be arranged on the tower body top air outlet 5, be arranged on the water seal 6 of tower body closed bottom liquid outlet; Said inlet mouth is through the air outlet of admission passage 7 connection gas blowers 8, and said admission passage is provided with and prevents that water is through the retrograde anti-return structure to gas blower of admission passage in the tower body.Said anti-return structure is that admission passage is designed to be inverted U type pipe, and peristome one end of said inverted U type pipe connects inlet mouth, and the other end is connected with blower outlet.The top of said inverted U type pipe admission passage is higher than the tower body top.Be connected with the inlet mouth below of side of said inverted U type pipe admission passage is provided with water discharge valve 9, and said water discharge valve is the pressure valve of a low pressure control.Said tower body is stripping tower or aeration tower tower body.
When malfunctioning or water tank overflow valve was inoperative when level control valve in the water storage tank, the water seal of tower body bottom just cannot stop the upwards retrograde of water, and water just is back to Ta Nei and gets in the inlet pipe of inlet mouth; When water column reaches the cat head height; Water is gone out by the cat head overflow earlier, and because the height of U type pipe is higher than cat head, water column can not get into air feed equipment through U type pipe; Stay water in the U type pipe just by the water discharge valve effect of inlet mouth below, discharge U type pipe.
As the improvement of the foregoing description, it is that with the different of the foregoing description said anti-return structure is the vacuum breaker that is provided with on the admission passage.
