Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Example 1

Referring to fig. 1-2, the embodiment provides an industrial split type high temperature heat exchange cooler, which includes a cooling pipe 3 disposed in a flue gas pipeline and a heating pipe 4 disposed in a blast pipeline; the cooling pipe 3 for cooling the high-temperature flue gas and the heating pipe 4 for preheating the cold air blown into the reaction chamber have the same structure; the cooling pipe 3 consists of a plurality of communicated coiled pipes 1, the water inlet of the cooling pipe 3 is a cooling pipe inlet 6, and the water outlet of the cooling pipe 3 is a cooling pipe outlet 5; the cooling pipe inlet 6 is positioned below the cooling pipe outlet 5, and the water flowing direction in the cooling pipe 3 is opposite to the smoke flowing direction; the outlet 5 of the cooling pipe is communicated with the water inlet of a first circulating water pump 7; the water outlet of the first circulating water pump 7 is communicated with the heating pipe inlet 8 of the heating pipe 4; a heating pipe outlet 10 of the heating pipe 4 is communicated with the cooling mechanism; the cooling mechanism is communicated with the liquid outlet 14; the liquid outlet 14 is communicated with a water inlet of a second circulating water pump 15; the water outlet of the second circulating water pump 15 is communicated with the inlet 6 of the cooling pipe; the arrangement is that after the cooling water in the cooling mechanism is blown into the cooling pipe 3 by the second circulating water pump 15, the cooling water in the cooling pipe 3 exchanges heat with the high-temperature flue gas through the surface of the coiled pipe 1, so that the heat of the high-temperature flue gas is transferred into the cooling water, the cooling water absorbs the heat and then becomes high-temperature boiling water and partial water vapor, then the first circulating water pump 7 works to send the high-temperature boiling water and the partial water vapor into the heating pipe 4, then the heating pipe 4 preheats the low-temperature air, so that the heat of the high-temperature boiling water and the partial water vapor is transferred into the low-temperature air, the low-temperature air is preheated, the high-temperature boiling water and the partial water vapor are converted into liquid water after the heat is dissipated, and then the liquid water is sent into the cooling mechanism, so that partial heat of the high-temperature flue gas can be transferred.

In order to make the water flow in the cooling pipe 3 and the heating pipe 4 smoother, two adjacent U-shaped pipes in the serpentine pipe 1 are communicated through a communicating pipe 2; two adjacent serpentine tubes 1 are communicated through a plurality of communicating tubes 2; with this arrangement, the flow of water in the cooling pipe 3 and the heating pipe 4 can be made smoother.

Further, the cooling mechanism comprises a cooling tank 11, branch pipes 12 and a spray head 13; water is added into the cooling tank 11, and a branch pipe 12 communicated with the heating pipe outlet 10 is arranged above the cooling tank 11; a plurality of spray heads 13 for spraying high-temperature water are equidistantly distributed at the bottom of the branch pipe 12; a blast mechanism for radiating high-temperature water drops is further arranged on one side of the cooling tank 11; with such an arrangement, since the high-temperature boiling water and part of the steam are absorbed by the cold air after passing through the heating pipe 4, the temperature of the water discharged from the outlet 10 of the heating pipe is still high, and the high-temperature water is thoroughly cold-cut, so that the high-temperature water is changed into water drops by the plurality of nozzles 13, thereby increasing the contact area between the water and the outside air, and realizing the thorough cooling of the high-temperature water.

The blower mechanism comprises a rotating shaft 16, fan blades 17 and a driving motor; a driving motor is fixed on one side of the cooling tank 11, and the rotating end of the driving motor is connected with one end of a rotating shaft 16; the number of the rotating shafts 16 is multiple, and the rotating shafts 16 are all rotatably arranged on the cooling tank 11; two adjacent rotating shafts 16 are adjacent to each other through a belt; and fan blades 17 for blowing air are arranged at one ends of the rotating shafts 16.

The working principle of the embodiment is as follows: after the cooling water in the cooling mechanism is blown into the cooling pipe 3 by the second circulating water pump 15, the cooling water in the cooling pipe 3 exchanges heat with the high-temperature flue gas through the surface of the coiled pipe 1, so that the heat of the high-temperature flue gas is transferred into the cooling water, the cooling water absorbs the heat and then becomes high-temperature boiling water and partial water vapor, then the first circulating water pump 7 works to send the high-temperature boiling water and the partial water vapor into the heating pipe 4, then the heating pipe 4 preheats the low-temperature air, so that the heat of the high-temperature boiling water and the partial water vapor is transferred into the low-temperature air, the low-temperature air is preheated, the high-temperature boiling water and the partial water vapor are changed into liquid water after the heat is radiated, and then the liquid water is sent into the cooling mechanism, so that the partial heat of the high-temperature flue gas can be transferred. Because high temperature boiling water and partial vapor are behind heating pipe 4, and its inside heat can not be absorbed by cold air completely, lead to still higher from the temperature of heating pipe export 10 exhaust water, in order to be convenient for carry out thorough cold cut to these high temperature water, consequently through a plurality of shower nozzles 13, become the water droplet with high temperature water to increase the area of contact of water and outside air, thereby can realize the thorough cooling to high temperature water.

Example 2
