Abstract
The utility model belongs to the field of environmental protection equipment and relates to a siphoning decontamination device with a centrifugal pump. The siphoning decontamination device with the centrifugal pump comprises a negative pressure tank, a siphon, and a pumping device. A blow-down valve is disposed at the bottom end of the negative pressure tank. A water injection pipe is disposed at the upper end of the negative pressure tank in a communicated manner. The upper end of the siphon is communicated with the negative pressure tank along the tangential direction of the negative pressure tank. The lower end of the siphon is inserted below the liquid level of a circulating pool. The pumping device comprises a centrifugal pump, a water outlet pipe, a water suction pipe and a motor, wherein the water outlet pipe and the water suction pipe are communicated with an outlet and an inlet of the centrifugal pump respectively and the motor is linked with the centrifugal pump. A one-way valve and a stop valve are sequentially connected onto the water outlet pipe. The centrifugal pump of the siphoning decontamination device can be mounted above the liquid level of the circulating pool, water supply reliability is guaranteed, and runing, operating and maintaining are facilitated. Granules in water in the circulating pool are further purified. The operation requirement of a boiler fume desulfuration system for circulating water is met.
Description
Technical field
Centrifugal pump siphon decontamination apparatus of the present utility model belongs to the environmental protection equipment field, relates in particular to a kind of trash-removal device.
Background technique
Existing boiler flue gas desulfurization system needs to add alkaline drug thereon in the clear liquid and carry out recycling after the water treatment by setting up multiple stage circulation pond precipitation desulfurization slag, and its existing problems are:
1. in the pump hole that needs centrifugal pump to be installed in to be lower than the circulating water pool liquid level, can normally move, so that centrifugal pump operation, operation, maintenance are very inconvenient.
If 2. centrifugal pump is installed in more than the circulating water pool liquid level, the centrifugal pump suction inlet needs connected sucking pipe to stretch into below the liquid level, and have one section by air partition in the pipe this moment, occurs idle running during the centrifugal pump operation, can't imbibition.Story needs first to be full of water in pipe, the suction pipe mouth installs the bottom valve sealing additional, and can only intake can not water outlet, with normal pumping.Because water body exists impurity and particulate matter in the circulating water pool, easily cause bottom valve to close tight and leak gas, leak, usually cause normally start-up and operation of centrifugal pump.
Summary of the invention
The purpose of this utility model is to propose a kind of centrifugal pump siphon decontamination apparatus of the normal start-up and operation of centrifugal pump.
The purpose of this utility model is achieved in that centrifugal pump siphon decontamination apparatus is comprised of negative-pressure cup, syphon tube and aspirator three parts, it is characterized in that: the negative-pressure cup bottom is equiped with blowdown valve, the upper-end surface connection is equiped with water injecting pipe, the syphon tube upper end-hole is communicated with negative-pressure cup along the tangent direction of negative pressure tank body, insert below the circulating water pool liquid level lower end, aspirator is by centrifugal pump, the outlet pipe that pump with this, entrance is communicated with respectively, suction sleeve, and form with the motor of this pump interlock, connect successively on the outlet pipe one-way valve and stop valve are housed.
Owing to the technological scheme of carrying out above-mentioned negative-pressure siphon and particulate matter cyclonic separation, this decontamination apparatus can be installed in centrifugal pump and be higher than the above position of circulating water pool liquid level, has guaranteed the reliability that supplies water, also so that move, operate, overhaul very convenient.Particulate matter in the water body is further purified, and meets boiler flue gas desulfurization system to the service condition of cycle water.
Description of drawings: the technical solution of the utility model is provided by following drawings and Examples:
Fig. 1 is centrifugal pump siphon decontamination apparatus structural representation.
Legend: 1, circulating water pool, 2, syphon tube, 3, spill pipe, 4, negative-pressure cup, 5, water injecting pipe, 6, suction sleeve, 7, blowdown valve, 8, outlet pipe, 9, front valve, 10, stop valve, 11, one-way valve, 12, centrifugal pump, 13, motor.
Embodiment: the utility model is not subjected to following embodiment's restriction, can determine concrete mode of execution according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, centrifugal pump siphon decontamination apparatus is comprised of negative-pressure cup 4, syphon tube 2 and aspirator three parts, and negative-pressure cup 4 is the two-port sealing, and top is cylindrical body, and the bottom is the cavity tank of cone, and the cone bottom is equiped with blowdown valve 7.The connection of cylinder tank body upper-end surface is equiped with water injecting pipe 5.Syphon tube 2 is that " shape cavity pipe, its upper end-hole is communicated with negative-pressure cup 4 along the tangent direction of cylinder tank body, below lower end insertion circulating water pool 1 liquid level.Below syphon tube 2 and negative-pressure cup 4 connectivity parts, connection is equiped with spill pipe 3 on the wall of negative-pressure cup 4.Aspirator is by centrifugal pump 12, the outlet pipe 6 that pump with this, entrance is communicated with respectively, suction sleeve 8, and form with the motor 13 of this pump interlock, the upper end-hole of suction sleeve 6 stretches in negative-pressure cup 4 tank bodies from cylinder tank body and circular cone tank body connecting part.Connect successively on the outlet pipe 8 one-way valve 11 and stop valve 12 are housed.
During operation, close first blowdown valve 7, open the valve of water injecting pipe 5 and spill pipe 3, by water injecting pipe 5 to negative-pressure cup 4 water fillings, when spill pipe 3 begins to overflow water, close simultaneously the valve of water injecting pipe 5 and spill pipe 3, open centrifugal pump 12 and draw water, because the water level of negative-pressure cup 4 descends, produce negative pressure in the tank, the water in the circulating water pool 1 is under the effect of negative pressure, by syphon tube 2 negative suction tanks 4, produce solid stream of water, guaranteed the normal operation of centrifugal pump 12.Because the water that syphon tube 2 sucks is tangentially to enter negative-pressure cup 4, so in this tank, produce rotary water current, particulate matter in the water body is under centrifugal force and action of gravitation, and the sewage draining exit that is brought to the circular cone tank body bottom of negative-pressure cup 4 by eddy flow is concentrated, so that water body is able to further purification.The particulate matter that accumulates can according to system's operation demand, regularly be opened blowdown valve 7 and discharge.
Above technical characteristics has consisted of most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs inessential technical characteristics, satisfies the needs of different situations.
