There is provided an exhaust gas processing apparatus configured to cause a processing gas to be exposed to or come into contact with a liquid and thereby detoxify the processing gas. The exhaust gas processing apparatus comprises a suction casing provided with an inlet which the processing gas is sucked into and with an outlet which the processing gas is flowed out from; a liquid tank configured to receive an outlet-side part of the suction casing and store the liquid therein; and one or multiple spray nozzles placed in the liquid tank. The outlet of the suction casing is arranged to be located above a liquid surface of the liquid stored in the liquid tank. The one or multiple spray nozzles are configured to spray the liquid from around the outlet of the suction casing to a peripheral part of the outlet.

Exhaust gas processing apparatus

A wet abatement system which can suppress the accumulation of foreign matters in a treatment gas line is proposed. There is provided a wet abatement system for detoxifying treatment gas by bringing the treatment gas into contact with liquid. The wet abatement system includes an inlet casing having an inlet port from which the treatment gas is let in and an outlet port provided below the inlet port and through which the treatment gas flows, and a liquid film forming device provided between the inlet port and the outlet port and configured to form a liquid film on an inner wall surface of the inlet casing. A heater configured to heat the inlet casing is embedded in an interior of a wall portion of the inlet casing, the wall portion constituting a portion situated above the liquid film forming device.

Wet abatement system

A servo regulator includes servo piston, a first pressure chamber and a second pressure chamber, a spool, a biasing member provided on an outer periphery of the spool and configured to bias the spool, a first support portion configured to support one end portion of the biasing member when the spool is moved to a first direction where the pressure in the first pressure chamber is raised, and a second support portion configured to support other end portion of the biasing member when the spool is moved to a second direction where the pressure in the second pressure chamber is raised, wherein at least one of the first support portion and the second support portion is detachably provided on the spool.

Servo regulator

A detoxifying devicehaving an inner wallthat forms a flow passagethrough which treatment gas flows includes a first pipingthat forms a part of the flow passage, a replaceable piping sectionthat forms a part of the flow passageat the position downstream of the first piping, and is connected thereto for sprinkling the cleaning water to remove the solid product adhering to the inner wall, and a second pipingthat forms a part of the flow passageat the position downstream of the piping section, and is connected thereto.

Detoxifying device, method of replacing piping section of detoxifying device, and method of cleaning piping of detoxifying device

Provided is a canned motor to be coupled to a vacuum pump and used as a rotary driving source for the vacuum pump. The canned motor includes: a stator core; a rotor provided on an inner side of the stator core; and a non-conductive can provided between the stator core and the rotor. The non-conductive can is configured to separate the stator core and the rotor from each other. The non-conductive can is made of resin, ceramic, or composite material thereof. The non-conductive can is bonded to the stator core with an adhesive.

Canned motor and vacuum pump

The fan scrubber is provided with a casing having a gas draw-in port and a gas ejection port, a fan disposed in the casing, a nozzle from which a liquid is jetted into the casing, and a canned motor connected to the fan. The canned motor has a main shaft connected to the fan, a rotor which rotates integrally with the main shaft, a stator disposed on the periphery of the rotor, a motor casing in which the rotor and the stator are housed, and a can which partitions the interior of the motor casing into a rotor chamber in which the rotor is disposed and a stator chamber in which the stator is disposed.

Fan scrubber and vacuum pump apparatus

A sealing structure for a vacuum pump motor which maintains the sealing properties of the vacuum pump motor in an ensured fashion, including a lead wire which is passed through an opening portion formed in a motor frame to be connected to a motor stator and a seal member which seals the opening portion. The lead wire includes a core wire portion and a covering portion which covers the core wire portion. The lead wire also includes a seal portion formed around at least part of the core wire portion inside the covering portion.

Sealing structure, vacuum pump motor including same sealing structure, and vacuum pump

In order to provide a vacuum pump motor which is free from rotation imbalance, there is provided a vacuum pump motorwhich is connected directly to a pump main shaftof a vacuum pump, including a motor rotorwhich is attached directly or indirectly to the pump main shaftand balance ringswhich are attached directly or indirectly to the pump main shaftat ends thereof which are spaced apart from end portions of a rotor core, wherein the balance ringscontain a material having anticorrosion properties.

The present invention relates to a dry vacuum pump unit capable of achieving ultimate pressure of about 1 Pa. The vacuum pump unit includes a main pump () disposed at an outside-pressure side, and a booster pump () disposed at a vacuum side. The booster pump () and the main pump () are coupled in series. The booster pump () has a higher pumping speed than that of the main pump (). Each of the main pump () and the booster pump () includes a pair of pump rotors (and), a casing () having an inlet port and an outlet port, and a pair of magnet rotors (and) rotatable with the pair of pump rotors.

Vacuum pump unit

A vacuum pump has a casing having an inlet port and an outlet port, and a pair of confronting pump rotors which are provided inside the casing and synchronously rotatable for drawing in a gas from the inlet port and discharging the gas from the outlet port. A motor for rotating the confronting pump rotors is a permanent magnet motor having a stator and a motor rotor. The motor rotor has an iron core and permanent magnets disposed within the iron core.
