Summary of the invention
Technical problem to be solved by this invention, be exactly for the deficiency existing for prior art, and a kind of technical scheme of hot-water boiler anticorrosion adjusting device is provided, first the program regulates boiler blow-down water to enter boiler discharging tube road according to boiler leaving water temperature, the flow meeting the circulatory system is mixed with water outlet, reduce the flow of boiler feed water, the hot water exported by hot-water boiler is and then before above-mentioned mixed water, according to boiler blow-down water temperature water pump, boiler water outlet pump is improved pressure and get to boiler blow-down water mouth and above-mentioned backwater Hybrid Heating backwater, turn back to hot-water boiler water inlet again, the backwater entering hot-water boiler is made to bring up to more than 50 DEG C by regulating the type of flow of above-mentioned hot water, the circulating water temperature entering each heating surface is made to bring up to more than 50 DEG C, this just makes the fume side wall temperature of each heating surface of hot-water boiler bring up to more than 50 DEG C, no longer there is condensation in each heating surface surface, also sour corrosion would not be produced.
This programme is achieved by the following technical measures: hot-water boiler anticorrosion adjusting device, comprise the heating hot water boiler with boiler hot-water outlet and boiler blow-down water entrance, described boiler hot-water outlet connects heating supply channel, described boiler blow-down water entrance connects heating water return pipeline, the feature of this programme is between the heating supply channel and heating water return pipeline near-end of heating hot water boiler, be connected with return water temperature adjustment pipeline, the water pump and the check valve that pipeline are equipped with series connection is regulated in described backwater temperature, regulate on the heating water return pipeline between pipeline at described boiler blow-down water entrance and hot water temperature and have temperature sensor, this temperature sensor is electrically connected with the input of temperature controller, the water pump described in output electrical connection of described temperature controller.The check valve preventing temperature regulation ducts water from refluxing is equipped with in position before boiler blow-down water pipe and hot water temperature regulate pipeline, before check valve, regulate pipe water far-end that boiler blow-down water Flow-rate adjustment pipeline is housed with hot water temperature, this pipeline is equipped with control valve, at the far-end in described boiler discharging tube road, temperature sensor is housed, temperature sensor is electrically connected with temperature controller, and temperature controller is connected with control valve.The concrete feature of this programme also has, and described temperature controller controls the return water temperature of boiler blow-down water entrance more than 50 DEG C.
The beneficial effect of this programme can be learnt according to describing of such scheme, and owing to connecting heating supply channel in boiler hot-water outlet in this scenario, described boiler blow-down water entrance connects heating water return pipeline; Being connected with backwater temperature adjustment pipeline between the heating supply channel and heating water return pipeline near-end of heating hot water boiler, regulate the water pump and the check valve that pipeline are equipped with series connection in described backwater temperature; The check valve preventing temperature regulation ducts water from refluxing is equipped with in position before boiler blow-down water pipe and hot water temperature regulate pipeline, before check valve, regulate pipe water far-end that boiler blow-down water Flow-rate adjustment pipeline is housed with hot water temperature, this pipeline is equipped with control valve, at the far-end in described boiler discharging tube road, temperature sensor is housed, temperature sensor is electrically connected with temperature controller, and temperature controller is connected with control valve.This structure, can be reduced boiler blow-down water flow by boiler blow-down water Flow-rate adjustment pipeline, reduces the flow entering boiler water, can reduce the cooling degree of recirculated water to boiler, can by the hot water of boiler export again by return water temperature adjustment pipeline
Send boiler blow-down water pipeline back to, improve the circulating water temperature entering boiler feed water mouth after mixing with boiler blow-down water, make it to reach more than 50 DEG C.The flow that recirculated water reduces is controlled by the controller be attached thereto, make it to control in rated temperature, controlled by temperature controller by the boiler blow-down water temperature heated, general control is more than 50 DEG C, this just makes the fume side wall temperature of each heating surface of hot-water boiler bring up to more than 50 DEG C, no longer there is condensation in each heating surface surface, also would not produce sour corrosion.As can be seen here, the anticorrosion that the present invention changes controls heating surface temperature and prevents dew point corrosion compared with existing galvanic cell aseptic technic, and have outstanding substantive distinguishing features and significant progress, its beneficial effect implemented also is apparent.The links such as environmental protection, energy-saving and emission-reduction, minimizing cost are added in beneficial effect suggestion.
