Purifying Coal Gas.

I GEORGE LOVE the Younger of Malton House Lanchester in the County of
Durham Engineer do hereby declare the nature of my invention for IMPROVEMENTS
IN CONDENSING APPARATUS FOR TREATING OR PURIFYING COAL GAS to be as
follows:
My invention relates to means for condensing or treating gas such as that given
off from coke-ovens, furnaces, gas-producers, and other places or sources of pro-
duction by causing the gas to pass through a vessel or chamber provided with
trays or screens and a current of water in a spray or divided state adapted to bring
the gas under treatment within the operation of the stream or spray successively
and thoroughly.
To carry my improvements into effect I arrange a suitable vessel or chamber so
that the gas on leaving the generator or furnace passes into the vessel where it
meets a spray or stream of finely divided water. The gas is by means of a
succession of suitable trays guided alternately to the outer edge or circumference
of the vessel and next to the interior or central portion thereof and so on to and
fro to the outlet pipe so as to expose a large surface of gas to the repeated
operation of the water. Preferably down the centre of the condenser is arranged
a water supply pipe for the purpose of supplying the succession of sprays or
showers of water through which the gas is guided by the various trays or divisions
in the chambers.
These various sprays or showers being supplied by their action cause a draught
or suction in the condenser which acting as an exhauster to the gas generator draws
gas therefrom to the condenser.
There may be any suitable number of such trays or divisions and sprays or
shower producers and supply pipes or the number of chambers in communication
or otherwise may be increased.
The gas operated upon passes away by a suitable outlet and the water with the
matters eliminated or separated from the gas pass to a suitable receptacle the liquid
in wbich seals the lower part of the chamber and from whence the liquid may be
pumped back for repeated use in the chamber or away as desired.

Purifying Coal Gas.
I GEORGE LOVE the Younger of Malton House Lanchester in the County of
Durham Engineer do hereby declare the nature of my invention for IMPROVEMENTS
IN CONDENSING APPARATUS FOR TREATING OR PURIFYING COAL GAS, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
My invention relates to means for condensing or treating coal gas such as that
given off from coke-ovens, furnaces, gas producers, and other places or sources of
production by causing the gas to pass through a vessel or chamber provided with
trays or screens and a current of water in a spray or divided state adapted to bring
the gas under treatment within the operation of the stream or spray successively
and thoroughly.
The accompanying drawings shew apparatus arranged and adapted to carry my
improvements into practical effect I have here shewn one form of a suitable vessel
or chamber A so that the gas on leaving the generator or furnace where it is
produced is caused by the action of the apparatus to pass by the pipe C into the
vessel A where at its entrance it immediately meets a spray or stream of finely
divided or series of divided streams of water indicated by dotted lines.
The gas is
by means of a succession of suitable trays a here arranged in a series of superposed
inclined series alternately springing from the inner tube B and the inner wall a¹ of
chamber A guided alternately to the outer edge a¹ or circumference of the vessel A
and next to the interior or central portion B thereof and so on towards the centre
and from it again, to and fro until at last it is conducted to the outlet pipe D and
thereby away for utilization the extended passage being arranged so as to expose a
larger surface of gas to the repeated operation of the jets or divided streams of
water to cleanse it and separate matters borne by it in suspension or otherwise.
Preferably down the centre, of the condenser is arranged the water supply pipe B
for the purpose of supplying the succession of sprays or showers of water B¹
through which the gas is guided by the various trays or divisions a in the
chamber A.
His the main pipe for supplying water to the pipe B.
These various sprays or showers B' of water ejected with sufficient spraying force
from the succession of jets B¹ by their action cause a draught or suction in the
condenser A which acting as an exhauster to the gas generator by the pipe C draws
gas therefrom to the condenser A.
There may be any suitable number of such trays or divisions a and jets, sprays
or shower producers B¹ and supply pipes or the number of chambers in communi-
cation or otherwise may be increased.
The gas operated upon as already stated passes away by a suitable outlet say
at D and the water that has performed its cleansing functions with the matters
eliminated or separated from the gas pass to a suitable receptacle F the liquid
rising over the line fin which seals the lower part of the chamber and from whence

page_text: the liquid may be pumped back for repeated use in the chamber A or it may be
drawn off or taken away as desired according to circumstances.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The method of and combination of means and apparatus substantially as
herein set forth for treating or purifying coal gas by the action of water in divided
streams or sprays impinging on the gas whilst being caused to pass in a circuitous
course between trays or screens in a closed chamber.
2. In apparatus for condensing or purifying coal gas by the aid of films, sprays
or divided forms of water caused to impringe thereon, the combination with a
condensing chamber A, a water spray or jets supply pipe B, trays or screens a, with
suitable gas supply and outlet pipes as set forth.
