Abstract
The utility model discloses an improved structure of a desulfurization process water supply mother tube. The improved structure is characterized in that a water inlet of the water supply mother tube communicated with a desulfurization process water tank is located in the bottom of the desulfurization process water tank. The improved structure is capable of increasing the supply volume of process water, eliminating the phenomenon of frequent shut-down of a process water pump caused by insufficient water supply and ensuring the safe and reliable operation of a desulfurization island.
Description
Technical field
The utility model relates to the sulfur removal technology water water main pipe in power industry.
Background technology
China's energy resources are to take coal as main, all contain element sulphur in raw coal, are discharged into the SO in atmosphere
2approximately have 90% from steam power station production combustion process.
SO
2be colourless irritant smell gas, soluble in water, can cause respiratory system various diseases and cancer.China's ambient air quality regulation, residential community SO
2average daily maximum concentration is 0.15 milligram every cubic metre, and surpassing this concentration is exactly SO
2pollute, can form harm in various degree to human body.
SO
2after being discharged into atmosphere, finally be oxidized to sulfur trioxide, together with other sulfide, fall to soil and water, form acid rain.Before sedimentation, these pollutants can transmit hundreds and thousands of kilometers, form regional pollution.
Control artificial source discharge SO
2amount, become the vital task of atmospheric environment protection, China is actively improving fuel structure, carries out cleaner production, to reduce SO
2discharge value.Therefore, flue gas desulphurization has great significance for reducing atmosphere pollution.
The Limestone-gypsum Wet Flue Gas Desulfurization Process of extensive use a few days ago is wet type desulfurizing, and the effect of the fresh water (FW) in wet type desulfurizing is even more important, and by it, guarantees the moisturizing of whole system, and component cooling water and system are rinsed.The safe and stable operation direct relation of fresh water (FW) the safe and stable operation of whole desulphurization system.
Existing desulfurization island is set carries out flue gas desulfurization, the desulfurization island fresh water (FW) is to adopt two-way to supply water: a road is steam turbine recirculated water backwater, and pressure is in the 0.1MPa left and right, and another road is fire water, only does standby.Normal operation must be used the recirculated water backwater, but, because the recirculated water pressure of return water is lower, can not meet field requirement fully.When the slurries system is used flushing water; particularly in the water yield that comes into operation during larger mist eliminator flushing; the water main pipe output is less than the system water amount; in feed water valve standard-sized sheet situation, the technique cistern water level constantly descends; because the reduction of water level causes technique water pump trip protection, cause fresh water (FW) to supply water and interrupt.
The utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of sulfur removal technology water water main pipe reconstruction structure is provided, to improve the fresh water (FW) output, eliminate because insufficient water causes the numerous jumping pump of fresh water (FW) pumping frequency, guarantee the safe and reliable operation of desulfurization island.
The utility model is that the technical solution problem adopts following technical scheme:
The characteristics of the utility model sulfur removal technology water water main pipe reconstruction structure are: the water inlet that the water main pipe be connected with the sulfur removal technology water tank is set is positioned at the bottom of sulfur removal technology water tank.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, in prior art, the height of fresh water (FW) water tank is 4m, and the overhead height of water main pipe reaches 8m, and the actual pipeline 4m that climbs, so just caused the unnecessary pressure loss, thereby reduced output more.The utility model reduces the height of the female pipe of periodical feeding, thereby meets the requirement of fresh water (FW) system water supply.Output increases to 200t/h by original 150t/h, has met the demand of the maximum 180t/h flow of technique water pump.Thoroughly eliminate the contradiction that water supply flow is less than fresh water (FW) system a maximum demand, guaranteed the safe and reliable operation of fresh water (FW) system.
2, compare and improve the recirculated water pressure of return water to guarantee the requirement of delivery, the utility model is by reducing recirculated water water main pipe height, to reduce duct pressure loss, improve water supply capacity, the former must increase tubing pump, so not only increase investment, and increased energy consumption and maintenance.
The accompanying drawing explanation
Fig. 1 is the utility model sulfur removal technology water circulation water system schematic diagram.
Number in the figure: 1 sulfur removal technology water tank; 2 water main pipes; 3 water inlets;
The specific embodiment
Referring to Fig. 1, identical with prior art is that the water supply of sulfur removal technology water is comprised of two parts, wherein water route A is come by steam turbine recirculated water, water route B route fire water is as standby, via the front and back valve of strainer C and strainer C to the technique water tank, bypass strainer D is set, and the front and back valve of bypass strainer D is arranged; Carry out supercharging by two technique water pump E, export fresh water (FW) to system each one, as the main frame cooling water, the uses such as pipe flushing water, absorption tower supplementing water.
The water inlet 3 of the water main pipe 2 that as shown in Figure 1, in the present embodiment, setting is connected with sulfur removal technology water tank 1 is positioned at the bottom of sulfur removal technology water tank.
Transforming the female pipe of sulfur removal technology cistern water supply as water main pipe by height 8m in the present embodiment directly is connected with the technique water tank bottom, reduced difference pressuring loss, improved output, eliminate the contradiction that water supply flow is less than fresh water (FW) system a maximum demand, guaranteed the safe and reliable operation of fresh water (FW) system.
