Embodiment 1

[0052] like figure 1 As shown, a spiral industrial associated exhaust gas waste heat deep recovery module, the module includes a housing 1, the top of the housing 1 is provided with a cold water inlet 3 and a hot water outlet 2, and the bottom is provided with a sewage outlet 5, and the module also includes Two heat exchange units 4 arranged side by side inside the shell 1 and respectively connected to the cold water inlet 3 and the hot water outlet 2;

[0053] The top port of one of the two heat exchange units 4 is connected to the cold water inlet 3, the top port of the other heat exchange unit is connected to the hot water outlet 2, and the bottom ports of the two heat exchange units 4 are respectively connected to the bottom heat exchange tube bundle both ends of 6;

[0054] Any heat exchange unit in the two heat exchange units 4 includes an intermediate heat exchange tube bank 7 connected between the top port and the bottom port of the heat exchange unit, and several sup...

Embodiment 2

[0066] like Figure 9 As shown, a spiral industrial associated exhaust gas waste heat deep recovery device, the device includes several groups of above-mentioned modules arranged side by side in the radial direction of the industrial associated exhaust gas channel 11, the cold water inlet 3 in any group of modules passes through the cold water branch pipe 16 It is detachably connected with the cold jelly pipe 17; the hot water outlet 2 in any group of modules is detachably connected with the hot water main pipe 19 through the hot water branch pipe 18.

[0067] Both the cold water branch pipe 16 and the hot water branch pipe 18 are provided with stop valves 20 .

[0068] The stop valve 20 arranged on the cold water branch pipe 16 and the hot water branch pipe 18 of each group of modules can control the operation of the corresponding modules. When the intermediate heat exchange tube bundle 7 of the device leaks, the shut-off valve 20 on the cold water branch pipe 16 and the hot...

Abstract

The invention discloses a spiral module for deep recovery of industrial associated waste gas heat and a device comprising the spiral module. The spiral module comprises a shell. A cold water inlet and a hot water outlet are formed in the top of the shell. A sewage outlet is formed in the bottom of the shell. The spiral module further comprises two heat exchange units, and the two heat exchange units are arranged inside the shell side by side and are connected with the cold water inlet and the hot water outlet correspondingly. A top port of one of the two heat exchange units is connected with the cold water inlet. A top port of the other heat exchange unit is connected with the hot water outlet. Bottom ports of the two heat exchange units are connected with the two ends of a bottom heat exchange pipe bundle correspondingly. The heat exchange pipe bundle is arranged in a spiral mode, and thus the heat exchange area of the unit volume can be enlarged within a limited space; outwards protruding spherical-crown-shaped dimples are arranged on the outer wall of a single heat exchange pipe, and are beneficial to reducing abrasion by flue gas particles; and by the adoption of the modular design, maintenance of a faulty module can be completed online, the equipment utilization rate is increased, and safe and stable operation of a unit is ensured.

Description

technical field [0001] The invention relates to the field of utilization of waste heat of industrial associated waste gas, in particular to a spiral type deep recovery module of waste heat of industrial associated waste gas and a device containing the module. Background technique [0002] my country's energy structure is dominated by coal, and the huge amount of energy consumption has caused serious problems in the domestic environment, especially air pollution. At present, the control of smog and other environmental problems requires rapid adjustment of the energy structure. Recently, the Chinese government has issued many policy documents aimed at promoting energy conservation and emission reduction nationwide. [0003] In September 2013, the "Action Plan for Air Pollution Prevention and Control" issued by the State Council clearly stated that all coal-fired power plants, sintering machines and pellet production equipment in iron and steel enterprises, catalytic cracking ...
