KALLE 2.409211 DEVICE FOR REMOVING PARTICLE DEPOSITS FROM GAS PURIFYING APPARATUS ASSOCIATED WITH GAS GENERATORS Filed May 26, 1941 Patented Oct. 15, 1946 DEVICE FOR REMOVING PARTICLE DEPOS- ITS FROM GAS PURIFYING APPARATUS ASSOCIATED WITH GAS GENERATORS Karl Torsten Kalle, Saflle, Sweden Application May 26, 1941, Serial No. 395,240 In Sweden February 17, 1941 8 Claims. 1
The resent invention relates to a device which renders possible the automatic removal of charcoal dust, carbon particles or like deposits from gas-purifying apparatus or returning such deposits to the oxidizing zone of a gas generator. To this end a jet device is combinedwith said gas-purifying apparatus and is so adapted and arranged in such communication with the exhaust pipe of the engine driven by the gas generator. that the energy of motion of the exhaust gases may be utilized for conducting away charcoal dust, carbon particles or the like deposits, which thus can either be blown out into the atmosphere for example or returned to the oxidizing zone of the gas generator.
The jet device preferably co-operates with a discharge pipe occupying a central and stationary position in the body of the gas-purifying apparatus, in combination with which pipe it forms a kind of injector, the intake gap of which is located in the gas-purifying apparatus. The said intake gap is adapted to be dependent upon the energy of motion of the exhaust gases, i. e., a spring-loaded element attempting to close the gap is counteracted by the pressure deriving from the energy of motion of said gasses and thus said energy tends to open said gap. The springloaded element referred to is so designed that it keeps the gap closed until the engine develops a certain speed and the rate of exhaust gas flow is-thereby rendered adequately large for the pressure developed thereby to open the gap and cause the charcoal dust, carbon particles and like deposits to be sucked in through the gap.
Forming part of the said jet device according to the invention are a nozzle and a push member operatively connected thereto, which latter is movable in a cylinder communicating with the exhaust pipe and spring-loaded. The nozzle is co-axially positioned with relation to and cooperates with the stationary discharge pipe centrally located in the gas-purifying apparatus and through which the charcoal dust, carbon particles etc. are removed.
. One embodiment of the subject-matter of the invention is represented diagrammatically by way of example in the accompanying drawing, wherein Fig. 1 represents a vertical section through the device according to the invention, whilst Fig. 2 shows on somewhat larger scale a section through thejet device.
In Fig. 1 th exhaust gas pipe I leaving the engine (not shown) is represented together with the associated sound damper or silencer 2. In
2 front of the silencer 2 is an extension 3 of the pipe, from which a pipe 4 branches out, the inlet mouth of which opens out towards the stream of exhaust gases so that the energy of motion of these gases can be utilized to create a pressure in the pipe 4. This pipe l is connected up to a jet device 5 which is associated with a gas-purifying apparatus, for example an air purifier 6 of the so-called cyclone type, to which the gas coming from the gas generator (not shown) passes through a pipe 'I and departs through the pipe lit, as indicated by the arrows in Fig. l. Centrally arranged in the said purifyin apparatus is a discharge pipe 8., the end of which remote from the purifying apparatus can either open out directly into th atmosphere at 9 or be connected to the gas generator 9a. This latter alternative can be app-lied with advantage on those generators in which a part of the combustion gases can be returned together with the suction air. As is known this can occur on charcoal gas generators, which are supplied with adequate thermal insulation so that a certain amount of excess heat is produced, which excess can be utilized in the reduction zone of the gas generator for reducing carbon dioxide to carbon monoxide.
In Fig. 2 which as already stated above represents the jet device on a somewhat larger scale than in Fig. 1 the branch pipe 4 is connected at It to the jet device which is situated in a cylinder I I, into which exhaust gases from the engine flow so that they pass through orifices I2 into a nozzle i3 forming part of the said jet device. Arranged above this nozzle I3 and co-axial therewith is the end I 4 of the aforementioned pipe 8, between which and the nozzle I3 a gap I! may be formed in the manner described below. The nozzle I3 is capable of being moved towards and away from the pipe end 14, the necessary movement being transmitted by means of a push member I 5 fixed to the nozzle and by means of a spring l6 fitted thereunder. This spring It tends to bring the push member l5 into such a position that the nozzle I3 abuts the end of the pipe I4.
Whenthe speed of the engineis increased to a, certain value it will be apparent that the pressure in the pipe I will also be increased and accordingly also th pressure in that part of the cylinder II above the push member I5, so that the resistance of the spring [6 is overcome and the push member moves downwards. In this way the gap I! is formed through which charcoal dust, carbon particles and the like are brought along from the cyclone gas purifier under the action of the fiow of exhaust gases across from the nozzle l3 to the pipe end M.
The size of the gap and the injector effect thus brought about is therefore dependent on the speed of the engine. The significance of this fact will best be appreciated if it is assumed for example that the generator is set into operation when the engine is at a standstill and only a suction fan or the like is operating. A certain amount of vacuum will then be created in the cyclone gas purifier (assuming a suction fan to be employed) and as a result air will be sucked into the cyclone purifier from the pipes 9 and 4 respectively through the gap l1, if this gap is not fully closed. This flow of air will exercise a certain diffusing and possibly even 4 paratus and having inlet means to receive solid particles from said apparatus, a jet movable relatively to said inlet means to control the introduction of solid particles from said apparatus into said conduit, a pipe adapted to lead exhaust gases from the engine to said jet, and means operatively connected to the jet and responsive to increase in pressure in said pipe for moving the jet relatively to the inlet means to open the latter only after the attainment of a certain minimum pressure of said gases, whereby exhaust gases flowing from the jet into the conduit will'induce the flow of solid particles from the apparatus into the conduit.
igniting effect on the generator gas, which in either event will certainly suffer deterioration, thus rendering starting of the engine more difficult. However, it is evident that the spring IE will keep the nozzle positively in engagement with the pipe end l4 so that the communication of the cyclone purifier with the external air remains blocked until the engine is actually running and has developed a certain speed and the speed of exhaust gas fioW in the jet device is adequately large for the carbon particles etc. to be sucked in through the gap l'l. As already stated, the charcoal dust and other deposits removed can then either be returned to the oxidizing zone of the gas generator or be blown out into the open air or possibly even collected in a buffer, pocket or th like.
The practical importance of the facility afforded by the present invention of readily removing dust, carbon particles and like deposits from the gas purifying apparatus will be so readily apparent to those with experience of such problems that no further explanation is necessary.
It will finally be appreciated that the present invention as represented by the embodiment described and illustrated herein is capable of a number of modifications particularly in regard to its constructional features Without its scope and basic principle thereby being exceeded.
