Reciprocating speed adaptive pulse injection device

Abstract

The present invention relates to a reciprocating speed adaptive pulse injection device, and belongs to dust removal devices. A hole plate has a plurality of holes, each hole is connected to a filter bag, both left and right guide rails are steel I-beams and fixed on two sides of the hole plate; the left and right rails each has a corresponding mobile platform, the left and right mobile platforms are connected by a horizontal injection tube; an outlet end of the horizontal injection tube is perpendicular to the mouth of the filter bag; an inlet end of the horizontal injection tube is connected to the outlet end of an electromagnetic pulse valve; the inlet end of the electromagnetic pulse valve is connected to a high pressure gas tank by a high-temperature resistant high-pressure gas pipeline; the high pressure gas tank is connected to the front end of the hole plate; an electric induction front panel is connected to the front end of the hole plate, an electric induction back panel is connected to the back end of the hole plate, an electric induction side panel is connected to the side edge of the hole plate, and all the three induction panels are used to reflect the location information of the horizontal injection tube; and a control device is connected to the left mobile platform. The present pulse injection device has advantages of simple structure and high reliability.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a reciprocating speed adaptive pulse injection device. Background technique [0002] At present, the bag filter is the equipment with the highest dust removal efficiency in the dry dust removal equipment, and the dust cleaning device of the bag filter is one of its important equipment. At present, the method of gas pulse jet dust removal is generally used for dust removal. The traditional pulse jet bag filter generally adopts the fixed pulse jet dust removal method. The production and control of this method are relatively simple, but in practice In use, due to the large number of pulse valves used, the damage of any one of the pulse valves will lead to the failure of the entire pulse injection system, and because there are too many failure factors, it is not easy to maintain and repair later.

At present, the method of gas pulse jet dust removal is generally used for dust removal. The traditional pulse jet bag filter generally adopts the fixed pulse jet dust removal method. The production and control of this method are relatively simple, but in practice In use, due to the large number of pulse valves used, however, the damage of any one of the pulse valves will lead to the failure of the entire pulse injection system, and because there are too many failure factors, it is not easy to maintain and overhaul

[0003] Among the currently used single-pulse injection devices, some adjust the position of the pulse valve in real time according to the blockage of each row of bags to achieve injection. This method has better real-time performance, but it relies on pressure sensors to detect the blockage of each row of bags. , each row of cloth bags needs to be installed with at least one pressure sensor, more pressure sensors are used, and the control system is complicated, which increases the factors that may cause failure, making it difficult to maintain and repair later

There are also some that use the pulse valve to move back and forth at a fixed speed to realize the timing injection of each row of bags. This method has a simple control system and is easy to maintain and repair, but its real-time performance is poor. The phenomenon that the injection frequency of a cloth bag is too high or the injection frequency is insufficient

Can not achieve the best blowing effect
