Boiler steam heating network with same operating mode as refrigerator

Abstract

The invention discloses a boiler steam heating network with the same operating mode as a refrigerator. The boiler steam heating network mainly comprises a boiler (1), gas use equipment (8), a closed pollution discharge machine (2), a closed oxygen remover (3), a closed condensed water recovery machine (7) and a water quality treater (4); a first outlet of the closed pollution discharge machine (2) is connected with a first inlet of the closed oxygen remover (3); a second outlet of the closed pollution discharge machine (2) is connected with a second inlet of the water quality treater (4); an outlet of the gas use equipment (8) is connected with an inlet of the closed condensed water recovery machine (7); an outlet of the closed condensed water recovery machine (7) is connected with a first inlet of the water quality treater (4); and an outlet of the closed oxygen remover (3) is connected with an inlet of the boiler (1). The boiler steam heating network forms a closed circulating system to prevent hard steam flash evaporation and discharge, direct discharge of condensed water, direct discharge of upper and lower pollution discharge, oxygen removal and dissipation, and realizes zero discharge of condensed water, zero pollution discharge and zero oxygen removal dissipation.

Description

technical field [0001] The invention relates to a heat supply device, in particular to a boiler steam heating network operated in a refrigerator type. Background technique [0002] Thirty years of reform and opening-up, the rapid development of flying has made the boiler heating network eat up most of the energy in our country like locusts, and its energy consumption accounts for 2 / 3 of the total energy consumption in the country! The waste caused by open operation is as high as 1 billion tons / year of standard coal! More than 2.8 billion tons of CO2 are emitted into the atmosphere every year, creating terrifying smog, which is threatening China! Every year, 15 billion tons of condensed water are discharged, and 1.62 trillion yuan is burned, accounting for 12.5% ​​of the country's annual fiscal revenue! Let the boiler heating network become the chief culprit of high energy consumption and high pollution, and the culprit of smog! Our treatment method that focuses on the the...

Problems solved by technology

[0003] Refer to the attached figure 1 , the existing boiler steam heat network open operation process flow chart, the boiler steam heat network is a side of the boiler heat network, her open operation is mainly manifested in the steam of hard steam and flash evaporation, deoxygenation and release, and sewage discharge Straight up to nine days, the sewage of the next sewage is discharged into the ditch, wasting 100% of the water and taking away 30-50% of the heat! The process is that the softened tap water enters the deaerator, and then enters the boiler to be sublimated into steam and then sent to the heat engine; after the steam transfers the latent heat of vaporization to the heat engine, it is reduced to water, and is discharged from the outside of the heat engine through a trap, and enters under the action of pressure difference. An open expansion tank is installed; since the pressure of the expansion tank is zero (one standard atmospheric pressure), the condensed water under pressure evaporates part of the condensed water instantly while releasing its own pressure, and at the same time breaks part of the condensed water into mist It is sprayed into the atmosphere, lingering over the open water tank with majestic momentum; due to the open system, more than 90% of the condensed water pipes are oxidized, and often unknown water enters the condensed water, polluting the condensed water, making the condensed water unable to When used, we had to drain all of them on the spot, resulting in the serious consequences of zero recovery of condensed water, losing 70-90% of water and wasting 25-35% of heat energy; deoxygenation and release are inevitable, which is the system for the system. The price paid for the process of deoxygenation! The energy consumption of deoxygenation is generally around 20%, of which the dissipation accounts for 5-8%; the energy consumption of the upper sewage discharge exceeds 10% of the heat energy, and the lower sewage discharge is the discharge of saturated water, the loss of water is 8-10%, and the loss of heat is 2 -3%; In addition, the measurement of the system has not yet been formed, and there is no ability to form it. It is all based on manual experience, and the work is in a fuzzy state! Therefore, the water loss of the open operation system working in a fuzzy state is as high as 100%, the heat energy loss is as high as 30-50%, the energy utilization rate is only about 30%, the sewage discharge is as high as 100%, and the CO 2 It should come as no surprise that a 30-50% increase in emissions and a 30-50% increase in energy costs
