Embodiment 1

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

[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 6 ends;

[0054] Any one of the two heat exchange units 4 includes an intermediate heat exchange tube bundle 7 connected between the top port and the bottom port of the heat exchange unit, and a number of support columns 8 that support the...

Embodiment 2

[0066] Such as Picture 9 As shown, a spiral type industrial associated exhaust gas waste heat deep recovery device includes several groups of the above-mentioned modules arranged side by side in the inner radial direction of the industrial associated exhaust gas channel 11, and the cold water inlet 3 in any group of modules passes through the cold water branch pipe 16. It is detachably connected to the cold water main pipe 17; the hot water outlet 2 in any group of modules is detachably connected to 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 a shut-off valve 20.

[0068] The shut-off 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 module. When the middle heat exchange tube bundle 7 of the device leaks, the shut-off valve 20 on the cold water branch pipe 16 an...

Abstract

The invention discloses a spiral type industrial associated waste gas waste heat deep recovery module and a device containing the module. The module includes a casing, the top of the casing is provided with a cold water inlet and a hot water outlet, and the bottom is provided with a sewage outlet. The module It also includes two heat exchange units arranged side by side inside the shell and respectively connected to the cold water inlet and the hot water outlet, the top port of one of the two heat exchange units is connected to the cold water inlet, and the top port of the other heat exchange unit is Connect the hot water outlet, and the bottom ports of the two heat exchange units are respectively connected to the two ends of the bottom heat exchange tube bundle. The spiral arrangement of heat exchange tube bundles of the present invention can increase the heat exchange area per unit volume in a limited space; the outer wall of a single heat exchange tube is provided with outwardly protruding spherical crown cells, which is beneficial to slow down the impact of smoke particles. wear and tear; modular design is adopted, and faulty module maintenance can be completed online to improve equipment utilization and ensure safe and stable operation of the unit.

Description

Technical field [0001] The invention relates to the field of utilization of industrial associated waste gas waste heat, in particular to a spiral type industrial associated waste gas waste heat deep recovery module and a device containing the module. Background technique [0002] my country's energy structure is dominated by coal, and the amount of energy consumption is huge, causing 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 nationwide energy conservation and emission reduction. [0003] In September 2013, the Air Pollution Prevention and Control Action Plan issued by the State Council clearly stated that all coal-fired power plants, sintering machines and pellet production equipment of iron and steel enterprises, catalytic cracking units of petroleum re...
