Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the advantage of the purpose of this utility model and technical scheme clearly understand, below in conjunction with accompanying drawing and example, the utility model is further elaborated.
As shown in Figure 1, a kind of building brick high temperature sintering flue gas heat-exchange unit, comprises air-introduced machine 1 and heat exchange tank body 2.The vertical setting of described heat exchange tank body 2 is also cylindrical, is provided with " S " type heat exchanger tube 3 in described heat exchange tank body 2.A spiral board 4 is provided with inside the below of described heat exchange tank body 2.In the gap of described " S " type heat exchanger tube 3, be provided with some air jet pipe A5 and air jet pipe B6, have some pores on the surface of described air jet pipe A5 and air jet pipe B6.Described some air jet pipe A5 are connected with same air inlet pipe A7, and described some air jet pipe B6 are connected with same air inlet pipe B8.
Further, described air inlet pipe A7 is connected with compressed air generator or steam raising plant with air inlet pipe B8, or the dust of compressed air vapours to " S " type heat exchanger tube 3 surface adhesion can be utilized to purge.When utilizing vapours to purge, because heat that steam is self-contained can reduce, the heat transfer effect of " S " type heat exchanger tube 3 with high-temperature flue gas is affected.
Further, described air inlet pipe A7 and air inlet pipe B8 are also connected with motor-driven valve 9 and booster pump 10 respectively, control the opening and closing of air jet pipe A5 and air jet pipe B6 and increase the pressure and jet velocity that purge.
Further, the motor-driven valve 9 on described air inlet pipe A7 and the motor-driven valve 9 of air inlet pipe B8 work or alternation simultaneously.Whole " S " type heat exchanger tube 3 is purged simultaneously, the dust of adhesion can be removed fast, but heat exchanging impact is larger.During alternation, air jet pipe A5 and air jet pipe B6 also alternation, can reduce the impact of heat exchanging while purging dust.
Further, be provided with some fins (not shown in FIG.) on the surface of described " S " type heat exchanger tube 3, increase heat exchange area.
Further, " U " type tube connector 11 is provided with below described air-introduced machine 1 and heat exchange tank body 2, enter in heat exchange tank body 2 after high-temperature flue gas baffling, in baffling process, the dust granules that in high-temperature flue gas, weight is larger sedimentation in " U " type tube connector 11 does not enter in heat exchange tank body 2.
Further, a ring jet pipe 12 is provided with in the below of described spiral board 4, described ring jet pipe 12 is connected with compressed air generator and side towards described spiral board 4 has some pores on the surface, can purge being attached to dust on spiral board 4.
Further, the connecting line between described ring jet pipe 12 and compressed air generator is provided with gas flow valve 13, the adjustable air mass flow purged spiral board 4.
Working method of the present utility model is:
High-temperature flue gas acts on through air-introduced machine 1, enters in heat exchange tank body 1 along " U " type tube connector 11.In the process, the dust granules that in high-temperature flue gas, weight is larger sedimentation in " U " type tube connector 11.High-temperature flue gas, when spiral board 4, forms eddy flow and carries out heat exchange with " S " type heat exchanger tube 3.When after work a period of time, air jet pipe A5 and air jet pipe B6 works, and utilizes compressed air or high steam to purge " S " type heat exchanger tube 3.Ring jet pipe 12 pairs of spiral boards 4 purge simultaneously.The dust departed from discharges heat exchange tank body 2 with high-temperature flue gas.After having cleaned, stop purging.In purge, heat exchange does not stop.
The utility model structure is simple, spiral board is provided with in the bottom of heat exchange tank body, high-temperature flue gas enters in heat exchange tank body through the mode that spiral board effect is High Rotation Speed, and carry out heat with " S " type heat exchanger tube and hand over, high-temperature flue gas can be avoided directly to rush at " S " type heat exchanger tube and pile up in impact place, and the high-temperature flue gas rotated can also force the dust be partly adhered on " S " type heat exchanger tube to discharge heat exchanger with flue gas.On the other hand; some air jet pipe A and air jet pipe B are provided with in the gap of " S " type heat exchanger tube; simultaneously or alternately utilize compressed air or high steam to purge " S " type heat exchanger tube; prevent the accumulated plugging of dust; the not good and internal pressure of heat transfer effect is caused to increase; safe and reliable, the service life of " S " type heat exchanger tube can be extended, the number of times of power generating ratio maintenance.
