Description
[technical field]
The utility model belongs to the purified water treatment unit, more particularly, relates to the dense water automatic recycling device of a kind of reverse osmosis secondary.
[background technology]
Existing 10T two-pass reverse osmosis purified water preparation facilities, be to adopt municipal drinking water after mechanical filter, activated charcoal filter pre-filtering, filter by 5 μ m accurate filters again, enter one-level RO film, prepare the one-level purified water and enter intermediate water tank by the pressurization of one-level high-pressure pump.The one-level purified water pressurization that the secondary high-pressure pump sucks intermediate water tank enters secondary RO film, produces the dense water of purified water and secondary at last.Original equipment be before the dense water of secondary can be partly refluxed to the I and II high-pressure pump in design, but electrical conductivity of water is higher from the beginning in the locality, is generally 400-600 μ s/cm, and the pollution speed of film is very fast, the corresponding reduction of water flux.Usually use one matting week after date, one-level RO film water production rate will take place can not the meeting tier 2 confluent, causes the secondary high-pressure pump can only intermitten service, the dense water of secondary also can be off and on like this.The dense water of secondary cuts in and out, and will cause the flow of one-level force (forcing) pump suction port suddenly big or suddenly small, thereby makes before the one-level film pressure fluctuated, and uneven pressure repeated stock RO film influences work-ing life of RO film.Raw water box (city water tank) position is higher than the reverse osmosis purified water device in addition, and the dense water of secondary can produce back pressure as directly being discharged into raw water box, and equipment is had a negative impact.Therefore the dense water of secondary can only be directly emitted, and cause the significant wastage of water resources, and the dense water conductivity of secondary is generally 40-60 μ s/cm, is far superior to the quality of tap water, should be collected utilization.
[utility model content]
The purpose of this utility model is the conserve water resource, improves raw water box water quality, and a kind of device that can reclaim the dense water of secondary automatically is provided, and improves raw water box water quality simultaneously, saves former water usage quantity.
The utility model solves the problems of the technologies described above by the following technical programs: the dense water automatic recycling device of reverse osmosis secondary, comprise a dense water water storage box that is communicated with secondary concentrated water discharge mouth, the water outlet of described dense water water storage box is connected with raw water box by water pump, be provided with the floating-ball level switch of a charged contact in the described dense water water storage box, and control described pump motor power switch by described floating-ball level switch, make it to disconnect or adhesive.
The utility model technical characterictic is that also described pump motor power switch is an alternating current contactor.
Principle of the present utility model is: the utility model is by putting into a charged contact float switch in dense water water storage box, by its control alternating current contactor, make it to disconnect and adhesive: when the water storage box water level reaches the last water level of setting, the float switch contact is connected, the adhesive of control alternating current contactor makes pump motor energising operation, and water is transported to raw water box, mix with tap water, as the former water use of purified water water manufacturing system.When water level was reduced to the low-water level of setting, the float switch contact disconnected, and alternating current contactor is discharged, and made the pump motor outage, and water pump stops automatically.
Advantage of the present utility model is: simple in structure, reasonable in design, and less investment, can reach the dense water of automatic recovery secondary, and don't influence the pressure before the one-level RO film, both save water resources, improve raw water quality again, prolonged the work-ing life of reverse osmosis membrane to a certain extent.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is electrical control figure of the present utility model.
[embodiment]
Referring to Fig. 1, Fig. 2, the dense water automatic recycling device of reverse osmosis secondary, comprise a dense water water storage box 1 that is communicated with secondary concentrated water discharge mouth by pipeline 2, pipeline 2 is equipped with and connects the termination soon, the water outlet of described dense water water storage box 1 is connected with raw water box 5 with water pump 4 by water meter 3, be provided with cable floating-ball level switch SQ in the described dense water water storage box 1, disconnect or adhesive by floating-ball level switch SQ control pump 4 electric power switch (alternating current contactor KM).Model of pump: BAW-150, flow: 5T/H, measuring apparatus adopts water meter 3, and FR is a thermal overload relay, and Q is an air switch.For the continuous smooth working of system,, select desired flow and the water pump of lift and the concrete size of water storage box through measuring and calculating concentrated stream amount.Need pay special attention to the water tank height and can not surpass secondary film pipe height of living in, water pump unit hour flow is slightly larger than the unit hour water storage, and 6 is electric control box.
During use, the dense water of secondary is collected into water storage box 1 by self pressure, after reaching certain liquid level, floating-ball level switch SQ senses the high-water signal, the float switch contact is connected, and control alternating current contactor KM adhesive makes pump motor M energising operation, water is transported to raw water box 5 mixes, as the former water use of purified water water manufacturing system with tap water.When water level was reduced to the low-water level of setting, the float switch contact disconnected, and alternating current contactor KM is discharged, and made pump motor M outage, and water pump 4 stops automatically.This device is according to the dense water water yield of secondary, opens automatically or switches off the pump 4, realizes the automatic recycling of the dense water of secondary.
In order to prevent to produce potential safety hazard with water contact part element leakage, this device has adopted two kinds of protection measures: 1, master loop adopts earth leakage circuit-breaker, when the electric leakage situation, disconnects current supply circuit.2, adopt isolating transformer T, the device that contacts with water adopts the power supply of 36V safety voltage, to improve security.Utilize switching on and off of contactor secondary contact, can control the relay indicating light on and off, indication water pump 4 working ordeies.So repeatedly, reach the automatic recovery of the dense water of secondary.When 10T two-pass reverse osmosis purified water water manufacturing system normally uses, can save about 60 tons of tap water every day, can save about 1500 tons of tap water, and be worth more than 3000 yuan in every month.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that under the situation that does not break away from principle of the present utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claims and equivalent thereof.
