Description
COAL GAS PURIFICATION APPARATUS
The present invention relates to coal gas purification apparatus.
It is known to provide an apparatus for the cleaning of synthetic gas pToduced from slag by chemical coal gasification, in which apparatus synthetic gas leaving the reactor is cooled down to a temperature at which the liquid slag droplets, capable of flight, of the synthetic gas are transferred into solid slag grains. In German patent specification No. P 29 33 548.6-43 (not belonging to the state of the art) of the applicant, a coolant bath, into which fall ~olid particles precipitated from a gas current in a gas conduction chamber, is provided in the lower ~ection of the gas conduction chamber in an apparatus of that kind. In this case, cooling bodies forming cooling sur-faces acted on by the coolant of the bath project into the gascurrent path of the gas conduction chamber.
It is desired to further develop such apparatus in such a manner that the gas current fed to a downstream waste heat boiler can be varied in terms of temperature within wide limits.
In addition, it is desired to provide a control in terms of quantity of the gas current conducted out of the gas conduction chamber lnto the waste heat boiler, in which connection it is to be considered that the gas current stands under a pressure of 40 to 80 bars and at the transition to the waste heat boiler still has a temperature of 650 to 800.
According to the present invention there is provided coal ga~ purification apparatus comprising wall means defining a substantially vertical pressurized chamber for cooling of gas ~h ' ~ . s .:

therein by cooling mean~, the chamber receiving a coolant bath in its lower section, a gas outlet duct extendlng obliquely relative to and communicating with the chamber, a waste heat boiler connected to the gas outlet duct, and coiled pipe heat exchange means arranged in the lower section of the chamber ad~acent to the wall means.
Through the arrangement of the heat exchange means in the lower section of the chamber, which receives the coolant bath, the temperature thereof can be regulated over a wide range, for which purpose there can be provided regulating means in a feed duct of the heat exchange means.
In one embodiment of the invention, there is provided an additional lateral gas outlet duct. A regulable portion of the gas current can be conducted through the coolant bath and evaporation of the coolant can be prevented through regulation of the temperature thereof by the heat exchange means in the bath. The heat exchange means in the lower section of the chamber preferably forms a $eed water preheater heating surface, 80 that a not inappreciable proportion of the heat energy can be recovered. Through the conduction of a part or the entire quantity of the gas current through the coolant bath and the regulation of the temperature thereof, the gas current can be provided with a desired water contert as is required for tifferent chemical proces~es, for example in the production of ammonia.
The arrangement of the heat exchange means at the wall means ln the lower section of the chamber does not obstruct the drawing-off of soot and slag components from the bath, and .
.~ ->85~4 the descent of the solid particles in the bath is not obstructed by the heat exchange means.
Embodiments of the present invention will now be more particularly described by way of example with reference to the accompanying drawings, in which:
Fig. 1 is a schematic sectional view of coal gas purification apparatus in a first embodiment of the invention, and Fig. 2 is a schematic sectional view of coal gas purifi-cation apparatus according to a second embodiment of the invention.
Referring now to the drawings, in Fig. 1 there is showncoal gas purification apparatus comprising a cylindrical outer shell 1, on an upper narrowed section 2 of which is placed a part 3 of a reactor. The part 2 with the corresponding section of the reactor forms a transition duct of the reactor into a gas conduction chamber 4 of the apparatus. A lining 5 of the reactor can form a stub pipe 6 pro~ecting into the chamber 4.
Gas flows in the direction of arrow 7 into the chamber 4 and from there, in the embodiment according to Fig. 1, in the tlrectlon of arrow 8 lnto a gas outlet duct 9 and from here into a downstream waste heat boiler 10. The ga~ current in the chamber 4 can be cooled down by, for example, known spray equlpement (not shown) provided at the level of or below the pgrt 2, ~o that the solid particles present in the gas rigidify and fall vertically downwards.
Ad~acent to the shell 1 there are provided vertical heat exchanger pipes 11, which form a closed shell and the lower ends of which connect with a common annular duct 12, to which . I
.
a heat exchange medium is fed through the duct 13. Steam produced in the pipès ll iB drawn off at the upper end of the apparatus. The shell of the heat exchange pipes 11 is appro-priately interrupted at the height of the outlet duct 9.
The lower section 14 of the shell 1 is substantially bell-shaped and holds a liquid bath 15, the surface of the bath being above the annular duct 12. Adjoining the lower section 14 at the base thereof is a collecting container 16 for solid particles which have precipitated and sunk down from the bath i5 and which c8n be drawn off from the container 16.
Arranged in the lower section 14 of the apparatus in proximity of the wall 17 of this section is a heat exchanger 18 to which a hest exchange medium is fed through a duct 19, the heated hest exchange medium being drawn off through a duct 20.
Arr8nged in the duct l9 is a regulating device 21 in the form of a pump or a valve.
When the tempersture of the gas current in the chamber 4 rises and gas at a lower temperature, with the ga~ quantity remsining constant, iB to be fed to the waste heat boiler, then the medium flowing through the heat exchanger 18 can be throttled 80 that the liquid of the bath lS is evaporated in the lower section 14 of the apparatus and the latent heat withdrswn from the gas current. Preferably, the ducts 19 and 20 are connected with a feed water container.
In the embodiment according to Fig. 2, a gas conduction chsmber 4 is again provided? which is surrounded by the shell of hest exchsnge pipes 11, this-shell in turn being enclosed by the outer shell 1. Disposed opposite to the gas outlet duct :.

9 ant opening into the chamber 4 is a further gas outlet duct 30, which is arranged in ~uch a manner that-the surface 31 of the bath 15~ which is above the annular duct 12 lies ~ust above the base of the duct 30. Other arranBements for bringing the gas current entirely or partially out of the chamber 4 through the bath 15 into the duct 30 will be self-evident.
The lower section 14 of the shell 1 of the apparatus again has the pipe coil heat exchanger 18 in the proximity of its wall, ant the further conatruction of the lower portion of the heat exchanger according to Fig. 2 corresponds to that according to Fig. 1.
A regulating device 33 can be incorporated in an outlet 32 of the waste heat boiler 10. By means of the device 33, the gas current can be entirely or partially conducted from the chamber 4 to the duct 9 or duct 30 after the gas current or partial gas current has permeated the bath 15. To avoid evapor-atlon of the liquid of the bath 15 when the gas current is conducted through the bath, whilst it absorbs liquid vapour to a greater or lesser degree, the bath liquid is cooled with the aid of the heat exchanger 18.
The liquid level in the section 14 can be regulated through feed of liquid. Since the pressure prevailing in the duct 30 and asubsequent duct leading to a feed preheater boiler (not shown) is lower by about 0.3 to 0.5 bars than the 2S pressure in the chamber 4, the bath liquld in the duct 30 reaches a corTespondiffg le~el.
In order to be able to regulate the gas flow from the chamber 4 to the duct 30, a regulating device 34 is connected .

The evaporation of the liquid of the bath 15 is in this case prevented by temperature regulation of the bath by means of the regulating device 21 of the heat exchanger 18. Because the heat exchanger 18 is constructed as a pipe coil exchanger, it has a large heat exchange surface but toes not obstruct the descent of solid components in the bath liquid.
Above the heat exchanger 18 there can be provided a further heat exchanger 36, which i8 regulable independently of the heat exchanger 18 and which has inlet and outlet ducts 37 and 38.
This additional heat exchanger 36 i8 enclosed by the lower sectlon lla of the shell of heat exchanger pipes 11 in such a manner that the gas flow into the bath 15 is conducted through about half the depth of the bath 15.
