Embodiment Construction

[0036] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] like figure 1As shown, a regenerative heat exchanger for waste heat utilization in the cement production process, the heat exchanger includes a first tube bundle 3 and a second tube bundle 4, a high-temperature flue gas inlet 5, a high-temperature flue gas outlet 1, and a low-temperature working fluid inlet 10. The low-temperature working medium outlet 8 and the shell 2, the first tube bundle 3 and the second tube bundle 4 are arranged in the shell 2, the first tube bundle 3 is used to circulate the flue gas produced in the cement production process, the second tube bundle 3 The tube bundle 4 is used to circulate the low-temperature working fluid, and the first tube bundle 3 and the second tube bundle 9 are intersected; the flue gas enters from the high-temperature flue gas inlet 5, passes through the first tube bundle 3, and then i...

Abstract

The invention provides a smoke inlet device, including an adjustable smoke baffle, a smoke dusting baffle, a shell, a dusting pipeline, and a smoke inlet pipeline, wherein the smoke inlet pipeline is arranged at a lower end, a smoke outlet end is arranged at an upper end, the dusting pipeline is arranged in the shell for housing and collecting the dust in the smoke, a regular dusting mechanism is connected to the inferior of the dusting pipeline; the shell is composed of a first vertical segment at the lower end, an outward incline segment connected to the first vertical segment, a second vertical segment connected to the incline segment and a horizontal segment arranged at top and connected to the second vertical segment, the adjustable smoke baffle is connected to the other end portion of the horizontal segment and adjusts the angle around the other end portion of the horizontal segment; the first vertical segment forms a smoke inlet, the dusting pipeline goes deep into the shell from the smoke inlet, the smoke dusting baffle is connected to the upper end portion of the dusting pipeline arranged in the shell; in the vertical direction, and the upper end and the lower end of the smoke dusting baffle are arranged between the upper end and the lower end of the second vertical segment. The repeatedly efficient dust removal of smoke can be realized, the dust stratification problem of devices in the flue is reduced to a large extent, and the heat exchange efficiency after the smoke enters a heat exchanger is improved.

Description

technical field [0001] The invention relates to a regenerative heat exchanger for utilizing waste heat in a high-efficiency cement production process, and belongs to the field of heat exchangers of F28d. [0002] Background technique [0003] With the rapid development of my country's economy, energy consumption is increasing day by day, and the problem of deteriorating urban air quality is becoming more and more prominent. It is urgent to save energy and reduce the emission of harmful environmental substances. In the common thermal power field, one of the main reasons for high energy consumption and serious pollution is that the exhaust gas temperature of the flue gas is too high, which wastes a lot of energy and causes environmental pollution. The cement industry is a high energy consumption and high pollution industry. The waste heat power generation system in the cement industry can recover and reuse the waste heat of exhaust gas to achieve the purpose of energy saving...
