Abstract
The utility model discloses a flue gas heat-exchange device. A water jacket 5 is arranged on an outer wall of a cylindrical body 3 of the device and a spiral pipe 4 is arranged in the cylindrical body 3. Flue gas passes through the cylindrical body 3. Water enters the water jacket 5 through an inlet pipe 6 and then enters the spiral pipe 4 through the water jacket 5, flows in an outflow tube 11 through the spiral pipe 4 and then enters a boiler. During the process, the heat in the flue gas is absorbed by water and the water temperature can be raised. The fuel gas heat-exchange device applied to improvement on the flue pipe part of an original fuel gas and oil burning boiler can achieve remarkable effects of energy saving and energy consumption reducing, cost reducing, boiler heat efficiency improving and contamination discharge reducing.
Description
The utility model relates to a kind of heat-exchanger rig, relates in particular to a kind of flue heat-exchanger rig that utilizes the gas fuel residual heat from boiler fume.
At present, the pollutant that causes China's atmosphere pollution mainly is a sulfur dioxide, and they are mainly caused by coal fire discharged.In order to change this present situation, in China to widely popularize the renewal of the equipment that replaces coal-burning boiler with the gas fuel boiler.Yet, this promote practice not only equipment drop into the expense height, and use cost also exceeds several times than coal-burning boiler, this is all common issue with that unit ran into of using the gas fuel boilers.
The purpose of this utility model be for address the above problem provide a kind of flue heat-exchanger rig it can make full use of the waste heat of gas fuel boiler, energy savings, thus reduce the operating cost of gas fuel boiler.
Above-mentioned purpose of the present utility model can adopt a kind of flue heat-exchanger rig to reach.This device is that water jacket is set on barrel wall, and spiral coil is set in the cylindrical shell, and its concrete technical scheme is as follows.
The utility model flue heat-exchanger rig comprises cylindrical shell, water jacket, water inlet pipe, outlet pipe with upper and lower reducing smoke pipe.Wherein, water jacket is set on the barrel wall, spiral coil places in the cylindrical shell, and water inlet pipe is communicated with water jacket, and outlet pipe is communicated with spiral coil, and water enters water jacket by water inlet pipe, flows into spiral coil from water jacket, sends into boiler by spiral coil through outlet pipe.
The utility model flue heat-exchanger rig, described water jacket are that an end is communicated with water inlet pipe, and the other end is communicated with spiral coil.
The utility model flue heat-exchanger rig, described spiral coil places in the cylindrical shell, and its water inlet end is communicated with water jacket, and the water side is communicated with outlet pipe.
The advantage of the utility model flue heat-exchanger rig is:
1, excavated the energy-saving potential of gas fuel steam generator system, made full use of the waste heat of gas fuel boiler emission flue gas, the water temperature that enters the gas fuel boiler is brought up to about 60 degree by 35 degree, and smog discharge temperature is by entering about 135 degree that drop to the chimney outlet about the degree of 210 before the cylindrical shell, improve the thermal efficiency, guaranteed the optimum discharge temperature of flue gas.
2, simple in structure, easily manufactured, versatility is good, so economical rationality is used for the transformation at original gas fuel boiler chimney position, can obtain significantly beneficial effects such as saving energy and reduce the cost, reduce cost, reduced pollutant emission.
Below in conjunction with accompanying drawing the utility model flue heat-exchanger rig is further described.
Fig. 1 is the utility model helical disk tubular type flue heat exchange energy saver schematic diagram.
As shown in Figure 1, the utility model flue heat-exchanger rig comprises the cylindrical shell 3 with upper and lower reducing smoke pipe 1,8, water jacket 5, spiral coil 4, water inlet pipe 6, outlet pipe 11.Wherein, upper and lower reducing smoke pipe 1,8 is connected with flue, water inlet pipe 6 is communicated with water jacket 5 outer walls, spiral coil 4 water inlets are communicated with the water jacket inwall, spiral coil 4 delivery ports are communicated with outlet pipe 11, condensation water drainage groove 10 is fixed on the reducing smoke pipe inwall of cylindrical shell lower end, and condensation water drainage pipe 9 is fixed on the reducing smoke pipe outer wall of body lower end, is communicated with condensation water drainage groove 10.In this programme, dress water in water jacket 5 and the spiral coil 4 pass through flue gas in the cylindrical shell 3, and flue gas is discharged from bottom to top.
Workflow of the present utility model is: by inlet pipeline 6 demineralized water in the deoxygenation water tank is sent in water jacket 5 in the body 3, the spiral coil 4, water absorbs the heat of flue gas, water temperature is raise, water after the intensification is sent into boiler by outlet pipe 11, and whole Inlet and outlet water process is controlled by the boiler replenishing water system.
