Embodiment 1

[0017] Example 1: A bag filter pulse injection test device

[0018] like figure 1 , figure 2 and image 3 As shown, it includes an air compressor 1, an electric control box 3, a safety valve 7 at the top, an air storage tank 6 with a water release valve 8 at the bottom, an air filter 9, a pulse valve 13, a pulse controller 15, an air bag 16 and the blowing pipe 18 with sixteen nozzles 26, one end of the air compressor 1 is connected with the electric control box 3 through the wire 2, and the other end is connected with the stop valve 5 and the left interface of the gas storage tank 6 through the pipeline 4 in turn, The right interface of the air storage tank 6 is connected to the air filter 9, the pressure reducing valve 10, the stop valve 12, and the pulse valve 13 in sequence through the pipeline 11. Connection, the injection pipe 18 with sixteen nozzles 26 passes through the air bag 16 and is connected to the pulse valve 13. The pulse valve 13, the injection pipe 18 and...

Embodiment 2

[0019] Embodiment 2: a kind of test method of pulse valve single injection air volume

[0020] Using the bag filter pulse injection test device described in Example 1, after filling the air bag 16 with compressed air, close the stop valve 12, set the opening and closing time of the pulse valve 13 by the pulse controller 15, and then open the pulse valve 13. Blowing, turn on the data acquisition instrument 25 at the same time, collect the pressure P1 in the air bag 16 before the injection, the pressure P2 in the air bag 16 after the injection and the temperature t of the compressed air in the air bag 16 through the data acquisition instrument 25, and then combine Knowing the local atmospheric pressure P0 and the volume V of the air bag 16, through the formula The single blowing air volume Q of the pulse valve 13 is calculated. The obtained pulse valve single injection air volume Q can be used to evaluate the performance of different types and batches of pulse valves; it can a...

Embodiment 3

[0021] Embodiment 3: A kind of test method of pressure change of blowing pipe end

[0022] Using the bag filter pulse injection test device described in Example 1, the air bag 16 is filled with compressed air, and the opening and closing time of the pulse valve 13 is set by the pulse controller 15, and then the pulse valve 13 is opened for injection, and simultaneously The data acquisition device 25 collects the pressure change data from the high pressure pressure sensor 29 on the blowing pipe 18 through the data acquisition device 25 . The obtained data of the pressure change of the injection pipe can be used to analyze and improve the design of the injection pipe, and to clarify the change of the injection pipe pressure when the parameters such as the size of the injection pipe and the diameter of the injection nozzle are changed, so as to guide the design of the updated injection pipe.

Abstract

The invention discloses a sack-duster pulse blowing test device and a test method thereof. The test device comprises an air compressor, an electric control case, an air storage jar, an air filter, a pulse valve, a pulse controller, an air sack and a blowing pipe provided with a plurality of blowing nozzles. The pulse valve, the blowing pipe and the air sack are fixed on a tubesheet box after the assembly. One side of the tubesheet box is provided with a plurality of target cloth sacks which respectively correspond to the plurality of blowing nozzles. The target cloth sacks provided with clothsack frames are supported by a bracket. The target cloth sacks, the air sack and the blowing pipe are provided with meters which are respectively connected with a data collector by conductive wires. The test method of the test device is as follows: the data collector collects data from the meters and obtains performance parameters of the blowing pipe so as to create a sack-duster pulse blowing database; and by means of optimum combination of pulse blowing parameters, a favorable condition is created for studying, designing and improving a pulse cleaning system of a pulse sack-duster.

Description

Technical field [0001] The invention relates to a test device for a bag filter, in particular to a pulse injection test device for a bag filter and a test method thereof. Background technique [0002] At present, the pulse bag filter is a kind of high-efficiency dust collection equipment, but there are many problems in the practical application of the project. Some of them have poor cleaning effect, and the filter bag resistance is large; Bags; some cleaning strength is uneven, affecting the cleaning effect. The performance of the pulse cleaning system is determined by the performance parameters of the injection pipe and the optimal combination of various injection parameters. To study, improve and improve the performance of the pulse bag filter, it is necessary to establish a pulse injection test system. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is: to provide a bag filter pulse injection test device and a test method t...
