Abstract
The utility model provides a drain recovery device for a raw water heater. The drain recovery device comprises the raw water heater, a hot steam pipeline and a raw water pipeline are respectively connected with an inlet of the raw water heater, an outlet pipeline of the raw water heater is provided with a by-pass valve, one branch outlet pipeline of the by-pass valve is connected with an ultra-filtering backwashing water recycling pool, one branch outlet pipeline of the by-pass valve is connected with a drain recovery tank, an outlet pipeline of the drain recovery tank is connected with a drain recovery pump, and an outlet pipeline of the drain recovery pump is connected with a middle water tank. In the technical scheme, because the by-pass valve is arranged on the outlet pipeline of the raw water heater, the drain recovery tank can be prevented from being polluted by drain water of disqualified quality; due to the facts that the drain recovery tank, a liquid indicator and the drain recovery pump are additionally arranged, and the drain water is recovered to the middle water tank, water resources are saved, meanwhile, the drain recovery pump is prevented from being started up and shut down frequently, and therefore the device is protected.
Description
Technical field
The utility model relates to water treatment of power plant equipment, refers to especially a kind of raw water heater drainage recovering device.
Background technology
Raw water heater is the equipment of directly using the Steam Heating fluid water, and hydrophobic is steam produces because pressure, temperature descend in pipeline condensate water.Hydrophobicly should discharge in time or reclaim, otherwise not only steam heat in absorption tube, affect vapor flow, serious will produce water hammer, causes serious consequence.
At present, in power production process, unit water consumption is to weigh a leading indicator of genco's performance driving economy.Ultra filtering reverse osmosis equipment is widely used in water treatment, as pre-demineralization plant.For guaranteeing that winter, the milipore filter water inlet reached requirement, before ultrafiltration, be provided with heater.The raw water heater drain recovery is to reduce the water treatment water loss, reduces a kind of method of water consumption.The raw water heater drain recovery equipment that power plant is used can not meet on-the-spot needs, shown by hydrophobic pressure, can't be recycled to tank top between 6 meters senior middle schools, and reclaim line performs practically no function.The ultrafiltration operation characteristic of power plant has determined that raw water heater can not move continuously, general operation all can be stopped transport 24 hours in 8 hours, the steam-heating system pipe material is perishable under wet environment, each raw water heater initial operation stage, drain water quality is defective, do not reach the recovery standard, be disposed to trench by the raw water heater blow-off line, wasted water resource.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of raw water heater drainage recovering device, to solve the problem of the hydrophobic waste of power plant.
For solving the problems of the technologies described above, the utility model embodiment provides a kind of raw water heater drainage recovering device, comprise raw water heater, described raw water heater import is connected with the unboiled water pipeline with the vapours pipeline respectively, described raw water heater outlet conduit is provided with bypass valve, an outlet pipeline of described bypass valve is connected with hyperfiltration reverse-rinsing water recovery pond, an outlet pipeline of described bypass valve is connected with the drain recovery case, described drain recovery case outlet conduit is connected with drain transfer pump, and described drain transfer pump outlet conduit is connected with intermediate water tank.
Wherein, described drain recovery case outlet conduit is connected with drain transfer pump successively with liquid level gauge, and described liquid level gauge and drain transfer pump are suitable.
Wherein, the material of described drain recovery case and described drain recovery case outlet conduit is the 361L stainless steel.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, by outlet of water heater install pipeline bypass valve, the underproof drain recovery of water quality, to hyperfiltration reverse-rinsing water recovery pond, is avoided polluting the drain recovery case; By increasing drain recovery case, liquid level gauge and drain transfer pump, utilize the secondary pressurized of pump, drain recovery, to intermediate water tank, is completed to hydrophobic recovery and reuse, saving water resource, avoid reclaiming the numerous start and stop of pumping frequency, protection equipment simultaneously.
The accompanying drawing explanation
Fig. 1 is the system diagram of the utility model embodiment raw water heater drainage recovering device.
［ main element symbol description ］
1: raw water heater;
2: bypass valve;
3: drain transfer pump.
The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model, for the problem of the hydrophobic waste of existing power plant, provides a kind of raw water heater drainage recovering device.
As shown in Figure 1, the utility model embodiment raw water heater drainage recovering device, comprise raw water heater 1, described raw water heater 1 import is connected with the unboiled water pipeline with the vapours pipeline respectively, by pump, provide certain pressure that vapours and unboiled water are injected in raw water heater 1 by a certain percentage, described raw water heater 1 outlet conduit is provided with bypass valve 2, an outlet pipeline of described bypass valve 2 is connected with hyperfiltration reverse-rinsing water recovery pond, at the raw water heater initial operation stage, water quality can be produced underproof hydrophobic, open bypass valve 2 and make the hydrophobic hyperfiltration reverse-rinsing water recovery pond that flow to, through hyperfiltration reverse-rinsing water, reclaiming pump beats to middle water treatment system, reenter water circulation, avoid hydrophobic inflow return water tank internal contamination equipment, reduce simultaneously outer displacement.
Wherein, an outlet pipeline of described bypass valve 2 is connected with the drain recovery case, for collecting qualified hydrophobic of water quality, the material of described drain recovery case and described drain recovery case outlet conduit is the 361L stainless steel, described drain recovery case outlet conduit is connected successively with liquid level gauge, drain transfer pump 3, described liquid level gauge and drain transfer pump 3 are suitable, when hydrophobic in the drain recovery case reaches certain liquid level, liquid level gauge is controlled and is started drain transfer pump 3, avoid drain transfer pump 3 frequent start-stops, protection equipment; After the drain recovery pump startup, the hydrophobic effect of playing secondary pressurized in the drain recovery case, make hydrophobic inflow intermediate water tank, reaches the purpose that drain recovery utilizes, during lower than certain value, liquid level gauge is controlled drain transfer pump 3 and is quit work when liquid level hydrophobic in the drain recovery case.
In such scheme, by outlet of water heater install pipeline bypass valve, the underproof drain recovery of water quality, to hyperfiltration reverse-rinsing water recovery pond, is avoided polluting the drain recovery case; By increasing drain recovery case, liquid level gauge and drain transfer pump, utilize the secondary pressurized of pump, drain recovery, to intermediate water tank, is completed to hydrophobic recovery and reuse, saving water resource, avoid reclaiming the numerous start and stop of pumping frequency, protection equipment simultaneously.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
