Carter Environmental Model 170 EHS HA Wet Type Dust Extractor

Carter-Midac EHS wet dust collectors are designed to cater for those applications where potentially explosive dusts such as aluminium and magnesium and other potentially hazardous applications.

Former Rolls Royce Machinery

This plant is one of several machines acquired during Rolls Royce's reorganisation of their manufacturing facility at Inchinnan, UK.
Their worldwide reputation for quality is reflected in the machinery and maintenance of their manufacturing plant.
Many of these machines include features that are necessary for the manufacture and servicing of high quality engine components,
but can provide a benefit to any industry.

Works by drawing the contaminated air through a linear spray generator baffle, which is designed to

a) Generate an intense self induced spray zone.

b) Impose a series of about turns on the airflow so that the dust particles are centrifuged at high velocity onto the walls of the baffle which are continuously irrigated by the water spray.

c) Facilitate collisions between water droplets and dust particles in the spray zone.

d) Create a final water curtain through which the air must pass before leaving the baffle system.

By these means, a very high percentage of the dust particles are trapped in the water which drains back into the bottom tank of the collector. The dust eventually settles out and accumulates at the base of the tank as a sludge prior to being manually raked up the inclined side of the bottom tank and removed from the collector when the plant ceases working.

After negotiating the baffle system, the air passes through the spray eliminators which remove entrained water droplets before the air is discharged from the unit via the fan.

 Electronic water controls are provided to maintain the correct working level in the unit to ensure efficient collection. On explosion or fire risk applications these controls are augmented to provide additional safeguards against continuing plant operation with collector malfunction.

Included in the arrangement explosion relief panels and a fully integrated monitoring system

Numerous access doors provide full facilities for easy inspection and maintenance. A drain valve is fitted so that the collector may be emptied for more complete inspection and cleaning.

A Self-induced spray wet collector powered by a powerful 30kW fan, providing high-efficiency levels up to 99%

This machine has been specifically designed for hazardous applications and was originally designed to extract and remove highly flammable  magnesium dust particles
