Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] like Figure 1-4 As shown, the catalyst detection pilot equipment of the present invention includes a box body 8, a top cover 10, a catalyst chamber 1, a flue gas return chamber 2, a cover 11 and a base 4;

[0026] A box is fixed on the base, and a flue gas return chamber is installed inside the box. The flue gas return chamber is supported in the box by a bracket. The catalyst chamber is fixed in the flue gas return chamber, and the top cover is covered on the box; the top cover and the box A hinge 9 is installed at the joint of one side, and the top cover can be flipped and opened along the hinge, and the top cover and the box body are provided with an insulation layer 3; the material of the insulation layer is aluminum silicate refractory fiber. The inlet end of the catalyst chamber is connected to the flue gas mixer 7, and the outlet end is connected to the flue...

Abstract

The invention relates to the field of catalyst test devices, in particular to pilot equipment for catalyst detection. The pilot equipment comprises a box, a top cover, a catalyst cabin, a smoke backflow cabin, a sealing cover and a base, wherein the box is fixed on the base; the smoke backflow cabin is mounted in the box; the catalyst cabin is fixed in the smoke backflow cabin; the top cover covers the box; and thermal insulation layers are arranged in the top cover and the box. Smoke in the pilot equipment for catalyst detection is reacted and filtered in the catalyst cabin and then backflowsfrom the smoke backflow cabin, the catalyst cabin is thermally insulated and heated, and the electric energy for heating is reduced, so that afterheat reutilization is realized; and a baffle plate and an electric heating plate are added to reduce the flow speed of the smoke in the backflow process and carry out temperature compensation, so that the catalyst cabin is better thermally insulated andthe afterheat utilization rate is increased.

Description

technical field [0001] The invention relates to the field of catalyst testing devices, in particular to a catalyst testing pilot equipment. Background technique [0002] With the increasingly stringent environmental protection requirements, there are higher requirements for coal-fired and power plant pollutant emissions. At present, the control of nitrogen oxide emissions is mainly through catalyst reduction technology. Catalyst denitration technology refers to the use of reducing agents under the action of catalysts Convert the nitrogen oxides in the flue gas into pollution-free water and nitrogen. The performance of the denitrification catalyst directly affects the denitrification effect of the SCR method. The catalyst manufacturer needs to test the catalytic performance of the catalyst produced by the catalyst pilot equipment, and simulate the flue gas denitrification process according to the actual situation to test the denitrification performance. [0003] In the exist...
