Description
SPECIFICATION
Apparatus for the discharge liquid slag and gas
The invention refers to an apparatus for the discharge of liquid slag and gasification gas from a
gasifier with a downward flow and liquid slag
discharge in a combined discharge of gas and slag.
The apparatus can be used in chemical industry for the gasification of fuels containing ash with liquid slag discharge.
An apparatus for the discharge of liquid slag and gas from a gasifier is known. This apparatus consists of a casing partially filled with water, which is provided with a branch overflow nozzle and another nozzle for the supply of gas and slag, which is arranged in the upper part of the casing and is designed like a cylinder having a throat with flowing outlines and consisting of a tube with constant cross section for cooling the gas and the slag. The tube is provided with a device for the distribution of the water over the inner surface area of the tube with the lower end of the cooling tube being arranged below the upper end of the branch overflow nozzle (Patent Specification 'Texaco' FR 2,326,465).
For the following two reasons this prior apparatus has a low reliability in service.
1. The apparatus is designed in such a way that the slag is formed into severai compact jets at the outlet of the nozzle. On discharging these jets swing and touch the wall of the cooling tube. Thus the water film is destroyed and the liquid slag comes into contact with the metal of the tube. In this way a starting point for slagging is formed.
Proceeding from this point the cross section of the tube completely slags. In some cases fusion of the tube wall was noticed.
2. The design of the tube for cooling the slag and gas with a constant cross-section results in a low convection heat exchange with the water film and heat exchange is realised nearly completely by radiation. However, radiant heat transfer for the purpose of cooling the gas flow containing liquid slag particles down to a temperature below the temperature of slag solidification requires very large dimensions of the tube for cooling the gas and slag (diameter and length).
Due to the large dimensions of the cooling tube the water film becomes irregular and unstable at a certain distance from the water distribution point.
In this process a part of the cooling tube wall burns due to the interaction with the gas flow and it slags because of the liquid slag particles contained in the gas flow.
Then step by step the section of passage of the cooling tube completely slags.
Furthermore, an apparatus for the discharge of gas and slag from a gasifier is known. This apparatus consists of a casing, which is partially filled with water and it is provided with a branch overflow nozzle and a nozzle for the supply of the liquid slag and gas. This nozzle is arranged in the upper part of the case and designed like a cylinder.
A tube having a constant cross-section for
cooling the slag and the gas is provided with a water jacket and a device for the distribution of the water over the inner surface area of the tube, the water forming a closed film flowing downwardly at the said inner surface of the tube, with the lower end of the cooling tube being arranged below the upper end of the branch overflow nozzle (Patent Specification GB 2 032 595).
For the following reasons this apparatus also has a low reliability in service.
1. The design of the nozzle for the supply of the liquid slag and gas like a cylinder causes a part of the liquid slag to leave the gasifier as a liquid film formed into several hanks, which swing when being discharged and touch the wall of the cooling tube. In this process the water film is destroyed and the liquid slag comes into contact with the metal of the tube. Thus a starting point for slagging is formed. Proceeding from this point the cross section of the tube completely slags. At increased velocities in the nozzle for the supply of gas and slag a part of the liquid film breaks up and enters the cooling tube in form of flakes with an analogous process being effected. The fluctuations of the flow of liquid slag increase.
2. The design of the tube for cooling the slag and gas which has a constant cross-section prevents the convected heat exchange with the water film from being very high, because high velocities of the gas flow cannot be obtained (in the case of high gas velocities the water film is destroyed and the tube wall is uncovered and slags). Therefore, the heat transfer has to be achieved by means of radiation, which requires very large dimensions (diameter and length) in order to ensure cooling the producer gas flow containing liquid slag particles down to the slag solidification temperature at the outlet of the tube. Large dimensions of the cooling tube result in an unstable and irregular water film at a certain distance from the device for the distribution of the water. In this case the wall can be locally uncovered or in interaction with the gas flow.
These points slag by liquid slag particles contained in the gas flow. Step by step the complete section of passage of the cooling tube slags and the cooling tube has to be put out of operation.
3. The arrangement of the lower end of the tube for cooling the gas and slag below the upper end of the branch overflow nozzle in order to obtain a wash layer for additional cooling and removing the solid particles from the gas results in the pulsation of the water layer and in the injection of the water into the cooling tube. In this way the operation of the tube is destabilized and the reliability of the device in service is reduced.
The object of the invention is to increase the reliability of the apparatus for discharge of liquid slag and gas.
The purpose of the invention consists in developing an apparatus for the discharge of slag and gas from a pressurized gasifier. This apparatus may be realized using small dimensions and the combination of purifying elements which ensures
a high reliability of the slag discharge, i.e. slag
offtakes remain free from choking.
According to the invention there is provided
"Claim 1". Preferably the bottom of the Venturi tube lies above the lateral overflow outlet nozzle.
Conveniently a nozzle for gas discharge may be
provided at the top of the central casing portion
and desirably the said supply nozzle is disposed at
the bottom of the gasifier.
By way of example an apparatus for the
discharge of liquid slag and gas, e.g. producer gas,
from a gasifier will be described with reference to
the accompanying drawing which is a
diagrammatical sectional elevation of the
apparatus.
A vertically disposed tubular casing 1 has a
supply nozzle 5 for supply of slag and gas at an
upper portion of the casing, a double-wailed tube
7 in a central casing portion, a bottom outlet
nozzle 3 for granulated slag discharge and a lateral
overflow outlet nozzle 2 for water collected in the
bottom of the casing portion. The double-walled
tube 7 constitutes a water jacket and at the top of
the tube 7 means 9 are provided for distributing
water over the innermost surface of the double
walled tube 7. A nozzle 8 is provided at the
bottom of the tube 7 to supply it with water.The
nozzle 5 constitutes a downwardly convergent tube disposed at the bottom of gasifier 1 0. The
inner wall of the double-walled tube 7 constitutes
a Venturi tube 6 consisting of a downwardly tapering section followed by a cylindrical section followed by a downwardly widening section. A lower part of the nozzle 5 is disposed within the downwardly tapering section of the Venturi tube
6. The apparatus has to satisfy the following relationship:
0.8.t < d < 1 .2t wherein d = the bore diameter
of the cylindrical section of the Venturi tube 6 and
t = the smallest internal diameter of the nozzle 5.
The use of the invention proposed allows the
reliability of operation to be increased for the
following reasons.
The design of the nozzle 5 for the supply of the
liquid slag and gas in form of a downwardly
convergent tube (supply of the gas flow at
velocities of 45 to 1 50 m/s in the smallest cross
section of the nozzle 5) allows the part of the
liquid slag leaving the gasifier as a liquid film to be
converted into particles of a small diameter (i.e.
the liquid slag is atomized into a highly-viscous
liquid).
In this process the gas flow entering the tube 6
for cooling the slag and gas contains all the liquid
slag in form of smallest droplets (less than 1 mm).
The reliability of the apparatus is considerably
increased because of the absence of a liquid slag
stream and slag film flakes. The velocities required
for the supply of the gas flow in the cross-section
of the smallest internal diameter of the nozzle 5
for the supply of the stag and gas normally range
from 45 to 1 50 m/s.
It was noticed that-at velocities of 45 m/s all
slags are atomizedwhich were obtained from
coals subjected to gasificatipn at normal temperatures for liquid slag discharge.
At velocities above 1 50 m/s abrasion of the nozzle 5 for the supply of the slag and gas was noticed at the narrowest point of the nozzle.
The design of the tube 6 for cooling the slag and gas in form of a Venturi tube allows the convection heat exchange to increase to such an extent that it is no longer necessary to use only radiant heat transfer for this purpose. Thus large cooling tube dimensions can be dispensed with.
Consequently, the Venturi tube 6 has a very small internal diameter and a very small length resulting in stability of the water film, increase in the water film thickness and increase in the reliability of the device in service.
It was shown by tests with the Venturi tube 6 carried out at high temperatures of the gas supplied (N1,5000C) into which solid particles were introduced, that no destruction of the water film occurs within the complete velocity range.
Experiments showed that the gas flow is dammed up above the downwardly convergent section of the Venturi tube 6, if the internal diameter d of the cylindrical part of the Venturi tube is reduced below 0.8.t, t being defined as above.
Consequently, the flow resistance of the Venturi tube 6 increases considerably. If the diameter d is increased above 1 .2.t, the gas penetrates the tube 6, but no considerable cooling of the gas is noticed.
The insertion of the lower part of the nozzle 5 for the supply of gas and slag into the downwardly convergent section of the Venturi tube 6 allows the distance for the slag particles passing from the point of breakage to the water film, where these particles suddenly solidify at the surface and lose their slaggability, to be reduced. This also increases reliability in service.
The arrangement of the lower end of the
Venturi tube 6 above the upper end of the branch overflow nozzle 2 prevents the water collected in the bottom casing portion from splashing back into the Venturi tube 6.
In this respect it can be said, that the Venturi tube 6 coupled with the water jacket system (double walled tube 7), represents a highly efficient cooling and washing device and the necessity of an additional wash layer can be avoided.
For liquid slag discharge the nozzle 3 may consist of tubes provided with pins and of a refractory ramming mixture above the pins.
By means of nozzle 2 provided in the bottom part of the casing 1 the water level is kept constant inside the casing 1.
From the gasifierthe liquid slag and gas, e.g.
producer gas, enter the nozzle 5 for the supply of slag and gas. In this process the liquid slag enters the nozzle 5 in two ways.
The portion of liquid slag accumulated on the walls and on the bottom of the gasifier is passed into the nozzle 5 in form of a liquid slag film. The other portion forms liquid slag droplets suspending in the producer gas flow. At the point of the smallest internal cross-section of the nozzle
for the supply of the slag and gas, the gas flow has
a velocity ranging from 45 to 1 50 m/s (e.g. 100
m/s). The slag film is torn off at the edge of the
nozzle 5 and atomized to particle sizes smaller than 1 mm (0.5 mm on the average). Thus all the
slag at the outlet of nozzle 5 is in a state of finely sprayed liquid particles. The flow is directed towards the inlet of the cylindrical part of the
Venturi tube 6, where it comes into contact with the water. Already at the inlet to the cylindrical part the flow is intensively cooled.In this process the liquid slag particles solidify very suddenly and lose their caking capacity. In the cylindrical part the flow is intensively cooled. In this process the liquid slag particles solidify very suddenly and lose their caking capacity. In the cylindrical part the flow is intensively cooled due to the high flow velocities (in the range of 100 m/s). The downwardly widening section of the Venturi tube serves for making an end of the cooling process and for partial restoration of the static pressure. At the outlet of the downwardly widening section of the Venturi tube the gas flow is separated from the water stream. The entrained solidified slag particles get into the water stream, are collected together with the water in the bottom casing portion, fall out of the water, collected in the bottom casing portion and are removed through nozzle 3.The water is discharged through nozzle 2 and the gas is discharged through another nozzle 4 in the central portion of the casing 1.
Examples of use of an apparatus described and illustrated by the accompanying drawing.
EXAMPLE 1
A producer gas flow discharged from a gasifier having a throughput capacity of 30 metric tons per hour of coal is passed to nozzle 5 for the supply of slag and gas, which nozzle 5 has an internal diameter of 300 mm in the smallest cross-section, under a pressure of 30 atmospheres and at a temperature of 1 ,5000C, at a velocity of 45 m/s in the smallest cross-section. The gas flow entrains liquid slag in form of very small particles amounting to 2,400 kg/h. In addition, 600 kg/h of liquid slag in the form of a slag film enter the nozzle 5. In the discharge cross-section of the nozzle 5 the slag film is atomized into particles of less than 1 mm.
In the cylindrical part of the Venturi tube 6 having a diameter of 240 mm a velocity of 70 m/s is maintained. The diameter of the cylindrical part is equal to 0.8 times the smallest internal diameter of nozzle 5 for the supply of slag and gas.
The gas flow and liquid slag particles intensively interact. They vigorously react with the water and the liquid slag particles are rapidly converted into the solid state.
EXAMPLE 2
The operation of the apparatus for the discharge of slag and gas is analogous to that of
Example 1. The throughput capacities of a gasifier.
having an efficiency of 100 metric tons per hour are as follows: producer gas 200,000 m3/h (normal conditions), liquid slag in the form of droplets 10 metric tons per hour, in form of a slag film 2 metric tons per hour. The smallest internal diameter of nozzle 5 for the supply of slag and gas amounts to 400 mm. The internal diameter of the cylindrical part of the Venturi tube 6 amounts to 1 .2.t = 480 mm. The velocity in the smallest cross section of nozzle 5 amounts to 1 50 m/s and in the cylindrical part of the Venturi tube to 105 m/s.
The liquid slag film is atomized into liquid slag particles of a diameter of 0.5 mm.
The apparatus proposed has the following advantages
1. Due to the following the probability of slagging of the tube 6 for cooling the gas and slag
Is practically equal to zero: There is no flow of liquid slag in the apparatus, the formation of large slag flakes is avoided and there is no possibility of formation of large liquid slag flakes, and the small liquid slag particles lose their caking capacity aiready at the outlet of the tube 6 for cooling the gas and slag.
2. Because of the use of a high-speed nozzle 5 for the supply of the liquid slag and gas and because of the use of a Venturi tube 6 the dimensions of the apparatus for the discharge of gas and slag are considerably reduced as compared with conventional practice.
These effects can be achieved, because according to the state of technology a considerably higher gas velocity is applicable and a different geometric form can be used. In this way a qualititatively different form of slag discharge is achieved.
