Problems solved by technology
[0002] With the rapid development of urban construction, more and more steam extraction heating units are used. At present, most units adopt the method of installing a regulating valve in the steam extraction and heating pipeline to meet the heat load, but the pressure adjustment of the regulating valve will cause energy saving. loss of flow, resulting in a decline in the economics of the power plant. At the same time, the power plant has high-quality hot water drained into the ditch, which is a pity to waste

Embodiment Construction
[0012] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes a heat network heater 2 connected to a steam extraction and heat supply pipeline 1. A regulating valve 3 is installed on the steam extraction and heat supply pipeline 1. A cold water inlet pipe 7 and a hot water outlet pipe are connected to the heat network heater 2. 8 and drain pipe 5, the hot water outlet pipe 8 communicates with the waste water pipe 9 of the power plant and a thermostat 6 is installed on the mixing pipe of the two, and a control valve 4 is installed between the cold water inlet pipe 7 and the hot water outlet pipe 8 The connecting pipeline, the control valve 4 is connected with the thermostat 6; the regulating valve 3 is in a fully open state during normal operation.
[0013] The regulating valve 2 on the steam extraction and heat supply pipeline 1 is in a normally open state, so as to isolate the steam turbine from the heating network pipeline wh...

The invention belongs to the application field of heating units, particularly discloses an intelligent heating network heater for recovering throttling loss and power plant waste heat water. The intelligent heating network heater comprises a heating network heater which is connected with a steam extraction and heat supply pipeline. The invention is characterized in that the heating network heater is connected with a cold water inlet pipe, a hot water outlet pipe and a drain pipe, the hot water outlet pipe is communicated with a power plant waste heat water pipe and a temperature controller is arranged on a mixed pipeline of the hot water outlet pipe and the power plant waste heat water pipe, a connecting pipeline with a control valve is arranged between the cold water inlet pipe and the hot water outlet pipe, and the control valve is connected with the temperature controller. The heater provided by the invention has simple structure, reasonable design and flexible application, is convenient to use and can achieve the effects of energy conservation and water conservation, no throttling loss in the regulating process and automatic temperature control and can satisfy the adjustment requirements of heat and power loads.
Description
(1) Technical field [0001] The invention belongs to the application field of heating units, in particular to an intelligent heating network heater for recovering throttling losses and waste hot water of power plants. (2) Background technology [0002] With the rapid development of urban construction, more and more steam extraction heating units are used. At present, most units adopt the method of installing a regulating valve in the steam extraction and heating pipeline to meet the heat load, but the pressure adjustment of the regulating valve will cause energy saving. It is a pity to waste the high-quality hot water in the power plant to drain into the ditch. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the invention provides an intelligent heat network heater for recovering throttling losses and waste hot water of power plants with simple structure and convenient operation. [0004] The present invention i...
