Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 The shown SCR denitrification device with a heat pipe type air preheater includes a deflector 2 and a rectifier 4 placed in the SCR denitrification reactor 3 , and a catalyst layer 5 arranged at the lower part of the rectifier 4 . A plurality of heat pipes 7 are arranged below the catalyst layer 5 in the SCR denitration reactor 3, and the heat pipes 7 are evenly distributed on the support plate 10 of the SCR denitration reactor 3, and are fixed in the SCR denitration reactor 3 by the support plate 10. At the same time, the support plate 10 and the wind zone partition 11 separate the SCR denitrification reactor 3 into an upper reaction zone, a primary wind zone, and a secondary wind zone. A flue gas outlet 6 is provided on the upper side of the SCR denitration reactor 3 opposite to the flue gas inlet 1 .

Abstract

The invention relates to a selective catalytic reduction (SCR) denitrification device with a heat pipe type air pre-heater. A guide plate, a rectifier and a catalyst layer are arranged in a reactor. A plurality of heat pipes are arranged below the catalyst layer, and the heat pipes are uniformly distributed on a supporting plate of the reactor. The heat pipes are fixed in the SCR denitrification reactor by the supporting plate, and the heat pipes and a fan partition plate form a primary air zone and a secondary air zone which are mutually independent, so that a denitrification effect can be ensured, integration of a heat exchange device and a reaction device is realized, and the problems of complex equipment, high manufacturing cost and the like of the conventional device are solved.

Description

technical field [0001] The invention relates to an SCR denitrification device with a heat pipe type air preheater. Background technique [0002] NOx is one of the main pollutants that cause acid rain and photochemical smog. Currently, in NH 3 Selective catalyst for reducing agent [0003] SCR technology is an effective way to remove NO in industry, but this process is greatly affected by operating conditions, and the investment, management and operation costs are high. The amount of boiler flue gas doubles, which will inevitably cause SO 2 and NOx emissions, seriously restricting the sustainable development of the country's economy and society. For the sustainable development of the environment and avoiding the old path of pollution first and then treatment, the national environmental protection department has gradually issued a series of regulations and policies to control NOx emissions from thermal power plants, and for some newly built and rebuilt and expanded project...
