Problems solved by technology

[0002] With the rapid development of urban construction, more and more pure condensing units drill holes in the connecting pipes from the medium pressure cylinder to the low pressure cylinder for heating and extraction. To meet the heat supply requirements of heat users, but the throttling process produces losses, resulting in a decline in the economy of the power plant, and the system cannot automatically adjust the heating temperature as the climate changes, resulting in waste of energy, and at the same time, it is limited by thermal power. , cannot meet the operation requirements of the power grid

Embodiment Construction

[0011] The drawings show a specific embodiment of the invention. This embodiment includes a heating network heater 2. A regulating valve 3 is arranged on the heating and air extraction pipe 1 connected to the heating network heater 2, and a cold water inlet pipe 7, a hot water outlet pipe 8 and a drain pipe are arranged on the heating network heater 2. A thermostat 6 is installed on the pipe 5 and the hot water outlet pipe 8, the control valve 4 is connected to the cold water inlet pipe 7 and the hot water outlet pipe 8, and the thermostat 6 is connected to the control valve 4.

[0012] The regulating valve 2 on the heating and air extraction pipeline 1 is in a normally open state, in order to isolate the steam turbine from the heating network pipeline when the steam supply is stopped. The cold water inlet pipe 7 and the hot water outlet pipe 8 that enter the heating network heater 2 are connected through the control valve 4. In the case of steam extraction without throttling, t...

Abstract

The invention belongs to the application field of heating units, and in particular discloses a device for improving the heating economy of a pure condensation reforming heating unit. The device for improving heating economy of the pure condensing reformed heating unit includes a heat network heater, which is characterized in that: a regulating valve is provided on the heat supply and exhaust pipe connected to the heat network heater, and a cold water inlet is provided on the heat network heater. Pipe and hot water outlet pipe, a thermostat is installed on the hot water outlet pipe, the control valve is connected to the cold water inlet pipe and the hot water outlet pipe, and the thermostat is connected to the control valve. The invention has the advantages of simple structure, convenient use, reasonable design, flexible application, no throttling loss, automatic temperature control, automatic adjustment of heat load, and no influence on electric load adjustment within the design range, and is suitable for wide popularization and application.

Description

(1) Technical field [0001] The invention belongs to the application field of heat supply units, and particularly relates to a device for improving heating economy of a pure condensate modified heat supply unit. (2) Background technology [0002] With the rapid development of urban construction, more and more pure condensing units have perforated heating and extraction steam from the connecting pipes of the medium pressure cylinder to the low pressure cylinder. At present, most of the heating extraction steam of the unit provides external heating by installing a regulating valve. In order to meet the heating requirements of heat users, but the throttling process produces losses, which causes the economy of the power plant to decline, and the system cannot automatically adjust the heating temperature with climate change, which causes a waste of energy and is restricted by heat and electricity. , Can not meet the operating requirements of the power grid. (3) Content of the ...
