Embodiment
For the purpose of this utility model, technical scheme and advantage is more clearly understood, with reference to embodiment and accompanying drawing,
The utility model is described in further detail, and exemplary embodiment of the present utility model and its explanation are only used for explaining this
Utility model, it is not intended as to restriction of the present utility model.
Embodiment：
As shown in figure 1, the system that the pump machine water shutoff in fume afterheat system is collected and recycled, this programme
Fume afterheat system refers to realizes wastewater zero discharge system using fume afterheat, and wastewater zero discharge system is realized using fume afterheat
In mainly have two equipment, i.e. demister 1 and concentration tower 2 when being rinsed, wherein demister 1 is arranged in concentration tower 2, demisting
Device 1 and concentration tower 2 are due to the particularity of working environment, and its impurity contained is more, it is necessary to often be rinsed, in this process
Substantial amounts of water is just needed to use, is all directly to introduce running water to be rinsed in the past, greatly wastes water resource.It is and actual
Realized using fume afterheat and many pumps have been used in wastewater zero discharge system, the WATER AS FLOW MEDIUM used to carry out the cooling of pump is referred to as
Machine water shutoff, although the machine water shutoff in each pump is limited, the machine water shutoff amount that large number of pump contains altogether with regard to considerable,
All it is usually directly to discharge it, first, the waste of water resource is caused, second, the moieties wherein contained will cause environment
Pollution, actually demister 1 and concentration tower 2 and corresponding pipeline be not high to water quality requirement when being rinsed, so this practicality
It is new to be just collected pump machine water shutoff to be rinsed to demister 1 and concentration tower 2 and corresponding pipeline.With demister
The flowmeter set in the pipeline that 1 this kind equipment is rinsed is named as flowmeter 2 11, and other utilization fume afterheat is realized useless
The flowmeter set in pipeline in water zero discharge system is named as flowmeter 1, and flowmeter 1 and flowmeter 2 11 are in figure
All represented with FI, flowmeter 1 and flowmeter 2 11 are all connected with a control valve 7 respectively, are entered according to the needs for rinsing branch road
Row control, control valve 7 uses automatic valve, by collecting pipe 4 by the pump realized using fume afterheat in wastewater zero discharge system
Machine water shutoff introduces collecting tank 5, and collecting tank 5 is arranged on to be realized below wastewater zero discharge system using fume afterheat, using liquid certainly
Density current enters collecting tank 5, reduces energy expenditure, while also the sealing in pump is protected, when the collection liquid level in collecting tank 5
When meter 12 monitors that the liquid level of machine water shutoff reaches setting liquid level, the machine water shutoff in collecting tank 5 is pumped into by the automatic start of collecting pump 3
Flush box 6, and monitor minimum liquid level autostop envelope collecting pump 3 of the liquid level less than setting.Filter is provided with flush box 6
Net, preliminary filtering precipitation is carried out to water, when the flushing liquid level gauge 13 of flush box 6 monitors that liquid level reaches setting liquid level, opened
Flushing pump 8 is opened, impure less machine water shutoff is passed into demister 1 by flushing water pipeline 10 and realized using fume afterheat
In pipeline in wastewater zero discharge system, liquid level stops flushing pump 8 automatically less than the minimum liquid level of setting.Flushing process is using artificial
Control, is rinsed as needed, and collects process using automatically controlling, and prevents collecting tank 5 from overflowing.Because demister 1 is set
In concentration tower 2 and it is located at the middle and upper part of concentration tower 2, the machine water shutoff being passed through under gravity can be successively to demister 1 and dense
Contracting tower 2 is rinsed, and control valve 7 is also provided between the equipment in fume afterheat system and pipeline, when flowmeter 1 and stream
When gauge 2 11 detects the minimum of water shortage setting therethrough, the water for illustrating now to be passed through is not enough to complete scavenger
Make, continue to be passed through and cause water resource and energy dissipation, it provides signal and causes control valve 7 to cut off the stopping work of flushing pump 8 after pipeline
Make, treat that new machine water shutoff enters flush box 6 or supplements other water to flush box 6, be again turned on control valve 7 and flushing pump
8 are rinsed work.When in machine water shutoff contain impurity it is few, or collecting pipe 4 introduce collecting tank 5 amount it is big when, can use collect
Tank 5 replaces flush box 6, reduces intermediate member, shortens intermediate step, improves time and the efficiency of flushing.The system can incite somebody to action
All machine water shutoffs enter internal system, for cleaning the equipment and pipe realized using fume afterheat in wastewater zero discharge system
Road, zero-emission is realized, while saving water resource and prevent environmental pollution.
Above-described embodiment, the purpose of this utility model, technical scheme and beneficial effect are entered
One step describes in detail, should be understood that and the foregoing is only specific embodiment of the present utility model, is not used to limit
Determine the scope of protection of the utility model, it is all within the spirit and principles of the utility model, any modification for being made, equally replace
Change, improve, should be included within the scope of protection of the utility model.
