Abstract
A method for recovering the technologically condensed liquid from the chemical fertilizer production apparatus features that the recovered technological condensed water is delivered into water tank via pipeline, on which the electric conductivity monitor, three-way valve, cooler and linked control system are installed. Its advantages are high safety for consuming the recovered water, and high automation level.
Description
Technical field
The present invention relates to a kind of process condensate recovery method, particularly relate to a kind of recovery technology of chemical fertilizer plant process condensate.
Background technology
In large, medium and small type chemical fertilizer plant, no matter adopting which kind of energy is raw material, the common feature of its technology is, the moisture that all contains some before the intermediate reaction thing of chemical fertilizer product and product are purified, remove, form condensed water after the evaporation, condensation through a series of technology, the common process condensate water that is called in the production, this process condensate water is chemical reaction water and steam condensate (SC), very pure, only treated slightly with regard to reusable edible.But because of retracting device perfect inadequately, can bring influence to follow-up water device during process condensate water parameter fluctuation, cause damage, therefore general chemical fertilizer plant all is that process condensate water is directly entered environment (not meeting environmental emission standard), fail to recycle, water resource has wasted, and environment is also impacted.
Summary of the invention
The purpose of this invention is to provide a kind of process condensate recovery method, a kind of recovery technology of chemical fertilizer plant process condensate particularly is provided, this process condensate reclaims the production safety that technology can guarantee follow-up water device, and process condensate is all reclaimed.
The objective of the invention is to realize in the following way: the pipeline that connects a suitable diameter in process condensate water (waste water after treatment) water tank a part is to the follow-up water tank of using, parameter is set (as pressure in the appropriate location of pipeline, temperature, flow, electricity is led, PH, turbidity, any parameters that need measurement such as trace thing) measuring instrument, the high precision three-way control valve, cooler (heater), the parameter information that measures is imported DCS or computer, the parameter information that measures compares processing with the parameter (parameter of follow-up water matching requirements) of artificial setting in advance by computer, when measurement parameter meets the parameter of artificial setting in advance, the computer output signal, drive the triple valve on the pipeline, triple valve is opened normal channel, process condensate water (or the waste water after handling) enters the follow-up water tank of using, and before entering with water tank through a cooler (or heater), to guarantee that water temperature meets the back technological requirement, this is the flow process under the production normal condition.When one of measurement parameter (or more than) does not meet the parameter of artificial setting in advance (parameter of follow-up water matching requirements), the same output signal rapidly of computer, drive the triple valve on the pipeline, triple valve is then opened another passage, and process condensate water (or the waste water after handling) enters trench or another flow direction, undesirable water can not enter water tank, guarantee water safety, simultaneous computer gives a warning, and the operator reacts, in time adjust parameter, make it recover normal flow.
1, reclaims process condensate water device therefor and effect thereof
(1) online conductivity monitoring instrument.Be used for measuring at any time the recovery electrical conductivity of water, what guarantee recovery is qualified water, guarantees follow-up safety with drainage facility.
(2) electric T-shaped valves.Being used for switching process condensate water is to reclaim or do not reclaim.
(3) coolers (according to reclaiming the selected heat exchange area of water yield size).Have certain water temperature when process condensate water effluxes usually,, need cooling for safety recovery and use better.
(4) one cover interlock control systems.Be used for being provided with the triple valve action and interlock, unusual or other setting interlocking parameter of water quality takes place when guaranteeing the recovery system operation, when reaching operation condition, triple valve can move, and guarantees the safety of follow-up water device.
Good effect of the present invention is: this process condensate reclaims the production safety that technology can guarantee follow-up water device, process condensate is all reclaimed, automaticity is very high, and is safe and reliable, and using every year at chemical fertilizer plant can be less with fresh former water hundreds of thousands ton; Because this process condensate water is very pure, need not processing procedures such as dosing clarification, as long as adsorption treatment just can be done boiler feed water a little, the annual benefit of process condensate water that reclaims is more than 1,500,000 yuan.
Equipment such as advanced measuring instrument, computer, Long-distance Control, high precision triple valve, cooler have been adopted; the flow process loop is advanced reliable; simple to operate; produce running steadily; maintenance capacity is special few; drop into after industrial production uses, be subjected to user's favorable comment, and very big for water saving, environmental protection meaning.
The accommodation of this process condensate apparatus for recovering is very extensive, and every industry that exists process condensate water (or waste water after treatment) needs to reclaim all adapts to, as numerous industries such as chemical industry, light industry, papermaking, electric power, printing and dyeing, food.
Accompanying drawing and description of drawings
Fig. 1 is a process flow diagram of the present invention.
Among the figure: 1 water tank, 2 measuring instruments, 3 computers, 4 triple valves, 5 coolers, 6 water tanks,, 7 trenches (another road flows to).
The specific embodiment
The process condensate water that needs are reclaimed causes recycle-water storage tank 1 (or other water occasion) with pipeline, the online conductivity monitoring instrument 2 of above-mentioned four recycle-water equipment needed therebies, electric T-shaped valve 4, cooler 5, interlock control system are just installed on this pipeline, conductivity gauge 2 is installed on the pipeline of triple valve 4 water inlets, triple valve 4 one sides are led to the recycle-water storage tank, one side is led to former outer drainage channel, and cooler 5 gets final product before being installed in the recycle-water storage tank.Main control parameters is as follows:
(5) electrical conductivity generally requires less than 50us/cm.
(6) temperature generally requires less than 50 ℃.
(7) other is thought and is necessary the technological parameter that is provided with, as long as can continuous measurement all can establish safety value.
Above-mentioned parameter be set to the to interlock safety value of action, just often process condensate water reclaims and uses, in case when process condensate water related parameter met or exceeded set safety value, triple valve promptly moved, water is guided to the former passage that effluxes, to guarantee the follow up device water safety.
Claims (4)
1, a kind of process condensate recovery method, the recovery technology that comprises a kind of chemical fertilizer plant process condensate, it is characterized in that: the process condensate water that will need to reclaim causes the recycle-water device with pipeline, and conductivity monitoring instrument, triple valve, cooler and interlock control system are installed on conduit pipe.
2, a kind of process condensate recovery method according to claim 1 comprises a kind of recovery technology of chemical fertilizer plant process condensate, and it is characterized in that: triple valve one side is led to the recycle-water device, and a side is led to former outer drainage channel.
