Embodiment

[0030] This embodiment has 8 discharge points.

[0031] first step, such as figure 1 As shown, the air volume and wind pressure at each discharge point are measured, usually an anemometer can be used directly. In this embodiment, the measured air volume and wind pressure at each discharge point are as follows:

[0032]

Air volume (Q)

wind pressure (p)

Emission point 1

10000Nm 3 / h

480Pa

Emission point 2

10000Nm 3 / h

530Pa

Emission point 3

20000Nm 3 / h

500Pa

Emission point 4

20000Nm 3 / h

620Pa

Emission point 5

30000Nm 3 / h

500Pa

Emission point 6

40000Nm 3 / h

440Pa

Emission point 7

50000Nm 3 / h

500Pa

Emission point 8

60000Nm 3 / h

500Pa

[0033] The above-mentioned air volume and air pressure are fixed values ​​during the working process, and generally do not change. The reason why the air volume and wind pressure are measu...

Abstract

The invention provides a multiple emission point exhaust gas volume matching collection and processing method. The method solves the problems in prior art of cumbersome system and high energy consumption. The method comprises the step S1 of measuring the volume at each emission point to obtain values Q1, Q2... QN; the step S2 of scaling down the values obtained in the step S1 to obtain values A1,A2... AN; the step S3 of summarizing and counting all possible different emission values between 0 and the sum of all the values obtained in step S2 in M kinds in total; the step S4 of assigning the Mkinds of different emission values in the step S3 to corresponding fan frequencies according to the site working conditions; the step S5 of taking operation signals of all emission points in a system, if the emission points operate, assigning the corresponding values in the step S2 to the corresponding emission points; if the emission points do not operation, assign zero; the step S6 of adding the emission values of all the emission points in the step S5; the step S7 of assigning the values obtained in the step S6 to the corresponding fan frequencies according to the assignment relation in the step S4, wherein the fan frequencies change in real time.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a method for collecting and treating waste gas with air volume matching at multiple discharge points, which has low energy consumption and is easy to operate. Background technique [0002] In the exhaust gas treatment system and the air-conditioning system of the factory building, the most frequently encountered problem is the mismatch between the fan system and the air volume value of the gas to be treated. Under normal circumstances, the technical designer of the project will properly reserve some margin when selecting the fan type, and then adjust the operating frequency of the fan through the frequency converter, and then adjust the processing air volume of the fan. When the inverter adjusts the operating frequency of the motor, it is generally used to arrange and combine multiple air intake points + multi-stage speed control of the inverter, and some technicians ...
