Abstract
The utility model discloses a vertical boiler waste heat energy-saving utilization device which comprises a heat exchanger, a temperature measuring device, a hot water tank, a bypass pipe, a vertical boiler, a water supply tank, a water supply pipe and a temperature display alarm control device. The vertical boiler is a main body member; a water tank-shaped heat exchanger is arranged on the outer wall of a smoke discharge chimney at the upper end of the vertical boiler; and the temperature measuring device is arranged in the heat exchanger and connected to the temperature display alarm control device. A hot water pipe and the bypass pipe are also connected with the heat exchanger; the lower end of the hot water pipe is connected with the water supply tank; and the water supply tank is connected to the vertical boiler through the water supply pipe. The pipeline of the water supply pipe is connected with the bypass pipe through a three-way joint and a control valve; and the bypass pipe is connected with the heat exchanger. According to the utility model, on the premise of not changing the whole structure of the vertical boiler, the heat exchange system is reasonably designed by adding a non-pressure heat exchanger to the chimney, thus the water in the water tank is effectively heated, the water supply temperature is increased, the smoke discharge temperature is reduced, and the boiler efficiency is improved. The device disclosed by the utility model has a simple whole structure, good stability and high reliability.
Description
Technical field
The utility model relates to a kind of vertical boiler residual heat integrative use device, relates in particular to vertical boiler afterheat energy-saving use device.
Background technology
Advantages such as at present, vertical boiler is simple because of using, occupation of land is few obtain widespread usage.But in use the ubiquity exhaust gas temperature is too high for such boiler, the shortcoming that heat loss due to exhaust gas is excessive.At present, vertical boiler effectively utilizes fume afterheat using enormous amount, can improve boiler efficiency greatly, helps the saving of the energy.
The utility model content
The purpose of the utility model is, overcomes the weak point of prior art, and a kind of vertical boiler afterheat energy-saving use device is provided; Be that fume afterheat through vertical boiler effectively utilizes; Reduce exhaust gas temperature, improve boiler efficiency, reach the effect of energy savings.
The described vertical boiler afterheat energy-saving of the utility model use device includes heat exchanger, temperature measuring equipment, boiler, bypass pipe, vertical boiler, feed-tank, feed pipe and temperature display alarm control device and forms.Vertical boiler is the main component of the utility model, on the smoke evacuation chimney outer wall of vertical boiler upper end, is provided with the heat exchanger of water tank shape, is provided with temperature measuring equipment in the heat exchanger, and temperature measuring equipment is connected to temperature display alarm control device.Be connected with heat exchanger, also be provided with hot-water line and bypass pipe, the lower end of hot-water line is connected with feed-tank, and feed-tank is connected to vertical boiler through feed pipe again.On the pipeline of feed pipe, be connected with bypass pipe with control valve through three-way connection, bypass pipe is connected to heat exchanger.The utility model is not changing under the integrally-built situation of vertical boiler, on chimney, does not have the heat exchanger of pressing through increasing, and the appropriate design heat-exchange system makes the effectively heating of water quilt of feed-tank, thereby improves feed temperature, reduces exhaust gas temperature, the raising boiler efficiency.The utility model has been considered the behaviour in service of heat exchanger under the different load according to the characteristics of vertical boiler operating load fluctuation, can under underload, utilize the water of original feed pump, feed-tank to carry out auxiliary circulation, guarantees that the heat exchanger water temperature can be not too high; Simultaneously, the water of feed-tank is effectively heated.Can guarantee like this whole system and equipment for a long time, stably the operation.
The described vertical boiler afterheat energy-saving of the utility model use device, overall structure is simple, installation and easy for operation, good stability, reliability is high.The utility model has adopted does not have the heat-exchange system of pressure; Under the situation that does not change prior art vertical boiler agent structure,, effectively utilized fume afterheat through on the chimney of prior art, adding heat exchanger; Reduce exhaust gas temperature; It is too high to have solved present vertical boiler exhaust gas temperature, and the problem that boiler efficiency is low has reached the effect of energy savings.Simultaneously, avoid heat exchanger under the underload situation, utilized heat energy insufficient, the phenomenon of dry combustion method occurred.
Description of drawings
Accompanying drawing 1 is the structural representation of the said vertical boiler afterheat energy-saving of the utility model use device.1-heat exchanger, 2-temperature measuring equipment, 3-hot-water line, 4-bypass pipe, 5-vertical boiler, 6-feed-tank, 7-feed pipe, 8-temperature display alarm control device.
