Description

The mixed water unit that is used to heat

?

Technical fieldThe present invention relates to the mixed water unit that is used to heat, belong to the heating power heating field.

Background technologyHuman civilization is also hidden crisis simultaneously in continuous progress, such as the environmental crisis that blindness economic pursuit benefit causes, and energy crisis etc., energy savings, the effective and reasonable theme that utilizes the energy to become current social using energy source.At present, the energy utilization rate of China in heating is still waiting to improve, such as: the building that in heating network, has is far away from heat source; This will cause the waterpower of heating pipe network unbalance; So up to standard for the heat supply that guarantees the far-end building, the center water circulating pump of thermal source is just essential to prolong running time.Traditional solution is in pipeline, to add a relay pump, and such result is that the far-end building heat supplying is up to standard, but it is unbalance new waterpower to occur in the system.The residing physical features of the building that has in the heat supply network is more much lower than the position of heat source, and the method for solution must be changed by upper plate, passes through the heat exchanger heat exchange again, the heat transfer process loses heat, and heat utilization efficiency is low, wastes energy.In addition, reheat,, improve the cost of heat supplying pipeline so the bore of water return pipeline is identical with the bore of supply channel because the water in the pipeline will all be got back to thermal source through water return pipeline.In addition; Heat exchange station adopts same heating network when hot user is heated at present, and hot user distance heat exchange station is far and near different, causes the hot user's of near-end heating to reach the heating temperature standard; And the hot user's of far-end heating standard does not reach; Like this, also need continue heating, cause the waste of energy consumption all users.

Summary of the inventionDefective in view of prior art exists the purpose of this invention is to provide a kind of mixed water unit that is used to heat.From thermal source architectural this unit that independently is provided with far away, this unit can not cause the waterpower of whole system unbalance again when guaranteeing that this building heat supplying is up to standard.

For realizing above-mentioned purpose; The technical solution that the present invention adopted is: the mixed water unit that is used to heat; It is characterized in that: thermal source is with once netting supply channel and once netting the water return pipeline connection and once net hot user; Once net supply channel and connect secondary net supply channel through unit; Secondary net supply channel is connected to the hot user of secondary net; The hot user of secondary net once nets water return pipeline through secondary net water return pipeline through the unit connection; Secondary net water return pipeline connects secondary net supply channel through mixing water lines, and unit is provided with check-valves b, control valve b, is provided with butterfly valve a, thermometer a, electric Pressure gauge a, filter a, control valve a, Pressure gauge a successively at secondary net supply channel and mixed water lines interface front end; Be provided with water pump, check-valves a, soft connection device, temperature sensor, flow sensor, Pressure gauge b, thermometer b, butterfly valve b at secondary net supply channel and mixed water lines interface rear end; Pipeline inserts the hot user of secondary net then, is being provided with butterfly valve c, Pressure gauge c, filter b, thermometer c, Pressure gauge d on the secondary net water return pipeline between hot user of secondary net and mixed water lines, secondary net water return pipeline to secondary net water return pipeline and once net and be provided with flow valve, pressure sensor, Pressure gauge e, butterfly valve d between the water return pipeline interface.

Said unit adopts VFC, also can adopt PLC to combine control with frequency conversion, can also set up touch-screen and Long-distance Control.

The mixed water unit that is used to heat, its beneficial effect is: set up water return pipeline, make and once net the backwater minimizing, widen the heat network system supply and return water temperature, improve the effective rate of utilization of heat energy; Because of water return pipeline backwater amount reduces, reduced return pipe backwater amount, promptly reduced the sectional area of transmission pipeline network, reduce equipment cost; On the secondary water-supply pipeline, be provided with water pump, make the thermal balance of heating network be able to guarantee, reduce energy resource consumption and waste; In the same heating system building of difference in functionality is realized independent heat supply control, make using energy source more reasonable.
