The so-called electromagnetic pulse valve refers to the airflow passing
through this valve when an instantaneous electrical signal is given, which has
short-term fluctuations like pulse phenomenon, so it is called pulse valve. The
electromagnetic pulse valve defined by the industry standard is a diaphragm
valve that is a combination of an electromagnetic pilot valve and a pulse valve
and is controlled by an electric signal.
The pulse valve is the actuator and key part of the pulse jet ash cleaning
device. It is mainly of right-angle type, submerged type and straight-through
type. Each type has several specifications. The connection port is 20-102mm
(0.75-4in), and more large size. The working pressure of domestic pulse valve is
0.4-0.6MPa for right-angle valve and straight-through valve, and 0.2-0.6MPa for
submerged valve; no matter which kind of valve of imported product, the working
pressure range is 0.06-0.86MPa, and there is no pressure and The difference
between high and low application power.
Pulse cartridge dust collector and Filter cartridge dust removal equipment The electromagnetic pulse valve blowing air volume is restricted by many
factors. How many filter bags (filter area) can be sprayed by an electromagnetic
pulse valve? A row of filter bags already knows the diameter, length and length
of the filter bags. How many inches of pulse valves are needed for the number of
filter bags? This kind of problem is often encountered, especially for those who
have just been engaged in the design of bag filters. This is the first answer he
needs. Indeed, the electromagnetic pulse valve is the key element of the pulse
jet bag filter dust removal system. Only when a dust collector has a reliable
and effective dust removal function can it maintain its set resistance and
ensure the normal operation of the equipment. But so far there is no method or
way to quickly determine the answers to the above questions, and there is no
formula for calculation.

The blowing air volume of the electromagnetic pulse valve is the key to
determining how many filter bags (filtering area) can be cleaned, but only the
blowing volume of the electromagnetic pulse valve is used to determine its
cleaning ability It's not scientific either. Because some pulse valves cannot be
closed in time and the blown air volume increases, apart from increasing the
consumption of compressed gas and wasting energy, it has no effect on cleaning
the filter bag. For a pulse valve with good performance and quality, its blowing
air volume is also restricted by many factors in the cleaning system: from the
input end of the pulse valve, the volume and pressure of the gas distribution
box, and the supply of the gas distribution box The inner diameter of the air
pipe and the air supply capacity of the air source directly affect the blowing
performance and blowing air volume of the same pulse valve: on the load end of
the electromagnetic pulse valve, that is, the filter bag it blows, the
temperature of the dusty gas that it filters, Humidity, dust concentration,
specific gravity and viscosity, filtration speed, equipment resistance will all
put forward different requirements for blowing performance and air volume. The
number and structure of nozzles (nozzles), filter bag material, diameter, length
and quantity, and dust removal. Various factors such as form (online, offline),
dust removal control (timing, constant pressure difference), etc., affect and
restrict the injection performance and dust removal effect of the pulse valve to
varying degrees.
