PLC (Programmable Logic Controller)

or DCS (Distributed Control System) is the core of automation

control of dust removal system. It is responsible for receiving

data from sensors, performing logical operations, controlling

actuators, and so on.

Used to detect the operating status of the system and

environmental parameters. Examples include pressure sensors,

temperature sensors, flow sensors, differential pressure sensors,

dust concentration sensors.

Includes motors, valves, pneumatic components,

etc., which are used to execute control commands.

Used for operator

monitoring and control system. HMI can display system status,

alarm information, historical data, etc.

It is used to connect various devices

in the system to achieve data transmission and information

sharing. Commonly used communication protocols include

Modbus,Profibus, Ethernet/IP and so on.

start and stop of the system is

controlled by PLC or DCS to ensure sequential start and stop and

avoid system shock.

control the starting and stopping and

running speed of induced draft fan, main fan and other motors to

maintain the system in the best working condition.

according to the set time or

differential pressure signal, automatically carry out filter ash

cleaning operation to maintain the filtering effect.

real-time monitoring of the system

status, timely alarm in case of failure, and take corresponding

emergency measures.

collect and record the data of

each sensor, which is convenient for subsequent analysis and

maintenance.

The dust removal control

system integrates a remote monitoring function, which allows

users to view and manage each parameter in real time, including

equipment operating status, pressure, fan speed, etc., through a

dedicated mobile application to achieve convenient and efficient

control and maintenance.

In 2023, Inner Mongolia Sonding

Environmental Protection and Energy Conservation Co.,

Ltd. cooperated with Siemens ICP team to build an intelligent

control cabinet production workshop, which is fully in

accordance with Siemens control cabinet standards, and

upgraded and imported in all aspects of electrical cabinet design,

production process, and quality control standards. This cooperation aims to bring the quality of electrical cabinets in line

with international standards. With an annual output of 260

standard control cabinets, this workshop can not only meet the

company's internal demand for control cabinets, but also provide

high-quality control cabinets in accordance with Siemens

standard

.SDHB TH4-NET, SDHB TH6-

NET, SDHB TH8-NET, SDHB TH12-NET, SDHB TH20-NET,

SDHB TH32-NET, SDHB TH64-NET, SDHB TH96-NET, and

SDHB TH128-NET can control up to 4, 6, 8, 12, 20, 32, 64, 96

and 128 solenoid valves, respectively. All pulse controllers have

a 10-digit display with 5 digits in the upper row and 5 digits in

the lower row, which can be adjusted via the rotary encoder and

the setup keys to show blowing time, blowing interval, total

number of air packs, total number of pulses, local address, shortcircuit current, disconnect current, output pulse value, and more.

The pulse controller can be queried, set and controlled by setting

encoder and OK key, and set remote or local control by

remote/local dip switch.SDHB-NET is equipped with a display

keypad, which can display the working status of the pulse

controller in real time, etc. The pulse controller can be adjusted

by setting encoder and OK key. All standard version energysaving pulse controllers are DC solenoid pulse valve outputs;

solenoid valve terminals are controlled through the control

terminal and common terminal, solenoid valve renewal diodes

are installed at the output of the instrument to reduce

interference, and an indicator light is set to indicate the status of

the output pulse. Each model is supplied in an ABS housing with

a transparent cover made of PC and is waterproof to IP68. The

SDHB-NET detects short-circuit and open-circuit conditions of

the pulse valve by sensing the current at the output port.s.
