Description
Technical Field
The invention relates to a device for gas-solid or gas-liquid separation, in particular to a horizontal type efficient cyclone separator.
Background
Cyclone separators are commonly used in the field of heterogeneous separation in chemical engineering, and are dry gas-solid separation devices that utilize the centrifugal force generated by a gaseous heterogeneous system when rotating at high speed to separate dust from a gas stream. Since the centrifugal force to which the particles are subjected is much greater than the gravitational and inertial forces, the minimum particle size of the cyclone separator which can be economically separated can reach 5 to 10 μm. In addition, the cyclone separator has simple structure, convenient operation and maintenance, stable performance, low cost and the like, is not limited by the concentration, the temperature, the physical properties and the like of dust-containing gas, and is widely applied to industrial production of petroleum, chemical industry, coal, electric power, environmental protection, metallurgy and the like. The cyclone separators are generally vertical, i.e. the separator bowl is arranged vertically, mainly to facilitate discharge of the material. When the air quantity processed by the cyclone separator is large, the requirement can be met only by a very large height space, and the requirement can not be met sometimes, for example, the vehicle-mounted mobile cyclone separator has strict limitation on the height of the carried goods due to the limit of the height of a national road, and the design scheme of the vertical cyclone separator cannot be realized at all; for example, the floor of a part of the factory building is limited in height and cannot be damaged, and the air inlet connecting pipe, the air outlet connecting pipe and the discharge port connecting pipe of the vertical cyclone separator also need to be at certain heights, so that the design of the vertical cyclone separator is often not feasible.
The cyclone separator operates mainly based on the centrifugal force and gravity, and when dust-containing airflow enters the vertical cyclone dust collector from the air inlet pipe at the speed of 12-25 m/s, the airflow changes from linear motion to circular motion. A substantial portion of the swirling air flow follows the wall from the cylinder in a spiral downward direction towards the cone, commonly referred to as "outer swirling flow". The dust-laden gas generates centrifugal force during rotation, throwing dust particles having a density greater than that of the gas toward the wall. Once the dust particles contact the wall, they lose their inertial force and fall down the wall by the momentum of the inlet velocity and downward gravity into the ash discharge pipe. When the descending external airflow reaches the cone, the descending external airflow is drawn towards the center of the dust remover due to the shrinkage of the cone. According to the principle of 'rotation moment' invariance, the tangential speed is continuously improved. When the airflow reaches a certain position at the lower end of the cone, the airflow continuously makes spiral flow, namely internal rotation, from the middle part of the cyclone dust collector from bottom to top in the same rotation direction. Finally, a part of the dust particles which are not trapped out of the exhaust pipe exhaust device can escape from the exhaust pipe.
The airflow motion in the cyclone separator is extremely complex, belongs to strong rotational flow of three-dimensional turbulence, and the structural style of the cyclone separator directly influences the separation performance. Secondary vortices are prevalent in cyclone separators, which consist of an axial velocity Vz and a radial velocity Vr, which have a large influence on the performance of the cyclone separator, in particular on separation efficiency, and several secondary vortices affecting cyclone efficiency are mainly concentrated in the head of the cyclone (i.e. the upper part of the cyclone cylinder), such as "upper vortex (or" short-circuit flow) "," longitudinal vortex flow ", and" local vortex in the outer cyclone ".
Theoretically, a horizontal cyclone separator configuration is possible, and the problem is mainly focused on how to eject dust particles thrown against the wall by centrifugal force out of the separator. The solution adopted in engineering is to bend the cone gradually downwards by 90 degrees (commonly called as 'ox horn bend' or 'shrimp bend'), which is common in small boiler flue gas dust removal equipment in early stages. However, the cyclone separation efficiency is obviously reduced, and the flow field inside the separator is greatly disturbed by the way that the cone bends downwards by 90 degrees, so that dust is extremely easy to be entrained and back mixed in the air flow at the turning positions of the internal rotation and the external rotation.
The Chinese patent ZL 201610062580.6 discloses a horizontal circulation cyclone separator with a guide cylinder, which consists of a horizontally arranged cylinder body, a guide cylinder coaxial with the cylinder body, a volute type air inlet pipe, two sealing end covers, two exhaust pipes, two dust separating pipes and two ash discharging pipes, and solves the problem that short-circuit flow is easy to form between an air inlet pipe orifice and the dust separating pipes. However, this horizontal solution also has several significant drawbacks: 1) The gas outlet needs to be connected with two exhaust pipes, and the connecting pipeline is too complex; 2) The ash discharge of the separator needs to be connected with two sets of ash discharge pipes, namely two sets of ash discharge valve systems are needed, so that the equipment cost is increased; 3) The separator is not suitable for the working condition of gas with pressure; 4) The separator does not solve the problems of entrainment and back mixing of the dust in the turning position of the internal rotation flow and the external rotation flow, namely, the internal rotation flow of the structure can entrain a large amount of dust into the guide cylinder and carry the dust out of the exhaust pipe.
The Chinese patent ZL 201410027461.8 discloses a horizontal gas-solid cyclone separator which consists of a gas-solid two-phase flow inlet, a gas outlet, a separator cylinder, a separator cone and a solid dust collecting box. The height of the flue gas outlet can be greatly reduced, the length of the flue gas outlet pipeline is shortened, and the structure is compact and the resistance is small. However, the horizontal gas-solid cyclone separator has several obvious defects: 1) Because the bottom of the horizontal cylinder body is provided with a long strip-shaped large slotted hole, the internal flow field (namely 'main rotational flow', including 'outer rotational flow' and 'inner rotational flow') of the separator is destroyed, the main separation mechanism is only similar to that of a flow guide baffle type gravity separator, and the separation efficiency is greatly reduced; 2) The solid dust collecting box occupies a larger height space, and is particularly obvious under the working condition of larger treatment air quantity; 3) The separator is not suitable for the working condition of gas with pressure.

The working principle of the horizontal type efficient cyclone separator of the invention is as follows: the impurity-containing gas is introduced into the separator by adopting a radial air inlet mode through the air inlet 22, so that the pressure working condition can be borne; the impurity-containing gas enters an annular gap between the central tube 2 and the middle cylinder 4 and rotates under the flow guiding effect of the spiral belt 5, dust particles or liquid drops in the gas are thrown to the inner wall of the central tube 2 under the action of centrifugal force, and the dust particles or liquid drops in the gas are primarily separated; with the gradual rightward rotation of the air flow, the air flow enters the volute outlet 7 consisting of the volute bottom plate 19, the volute top plate 21 and the volute plate 20, at this time, the air flow rotates faster, and enters the outer cylinder 8 under the diversion effect of a plurality of axisymmetrically arranged volute outlets 7, and dust particles or liquid drops are thrown to the inner wall of the outer cylinder 8 under the action of strong centrifugal force.
Since the gravity (vector) direction is parallel to the centrifugal force (vector) direction at this time, it is difficult to discharge the dust particles or droplets thrown toward the inner wall of the outer cylinder 8 by the centrifugal force out of the ejector. The prior art solutions have large interference to the flow field in the cyclone separator, which is very easy to cause dust to be entrained and back mixed in the air flow at the turning position of the internal rotation and the external rotation, thereby greatly reducing the efficiency of cyclone separation to trap dust particles or liquid drops. Thus, the guiding double cone 9, the vortex breaker assembly 14 and the reflector cone assembly 13 minimize flow field disturbances to the inside of the cyclone separator and guide dust particles or droplets out of the separator.
The gas flow to a certain area of the rear of the front cone 91 achieves a natural reversal from "outer swirl" to "inner swirl", i.e. in complete mechanism with a usual vertical cyclone separator, its "main swirl" comprises "outer swirl" and "inner swirl". However, in the tail region of the "main cyclone", a small portion of the gas (referred to as "wake vortex") still enters the rear cone 92, the "wake vortex" gas entrains dust particles or droplets and still rotates, but at this time, the gas rotation strength is gradually weakened, the dust particles or droplets in the region gradually drop to the lower part of the outer cylinder 8 due to losing centrifugal force, the gas-solid (liquid) two-phase "back mixing" in the region is very serious, if not limited, the central gas flow rotating by the "wake vortex" can re-wind the dust particles or droplets and escape through the central tube 2, the cyclone efficiency is seriously affected, at this time, the dust particles or droplets thrown to the wall by the centrifugal force can be separated from the central rotating gas flow by the vortex-preventing component 14, and when the dust particles or droplets reach the vicinity of the rear cone 92 along with the centrifugal force, the dust particles or droplets enter the annular gap between the front cone 91 and the vortex-preventing cone 141, and due to the shielding effect of the vortex-preventing component 14, only a small amount of the gas of the "wake vortex" can rotate to enter the space between the outer cylinder 8 and the vortex-preventing component 14, the centrifugal force is relatively sealed, and the dust particles or droplets quickly drop to the dust particles or droplets under the action of gravity to the gravity and drop to the dust particles from the bottom of the ash bucket 16 and fall out of the ash bucket 16. In the tail region of the main cyclone, a small amount of air flow rotating in the center of the wake vortex still contains a small amount of dust particles or droplets, the part of air flow rotating in the wake vortex penetrates into the vortex-preventing assembly 14, the small amount of dust particles or droplets are accelerated by centrifugal force due to the small diameter of the vortex-preventing cylinder 142 and are thrown onto the inner wall of the vortex-preventing cylinder 142, when the air flow reaches the tail end of the vortex-preventing cylinder 142, the dust particles or droplets enter an annular space formed by the vortex-preventing cylinder 142 and the reflecting cone assembly 13, and due to the fact that the rotation speed of the air flow is greatly reduced, the dust particles or droplets lose centrifugal force and fall into the bottom space of the outer cylinder 8 and the right large seal head 12 under the action of gravity and gradually fall into the ash bucket 16 through the slotted holes 111 of the fixed annular plate 11. The air flow with the center rotating in the wake vortex enters the reflecting cone assembly 13 and then bounces back, namely the air flow keeps the same rotation direction and opposite directions, finally flows into the internal rotational flow and flows out through the central pipe 2 and the exhaust port 1.
Referring to fig. 11 and 12, after the horizontal type efficient cyclone separator is adopted, under the same technological condition, compared with the prior art, the separation efficiency of the horizontal type efficient cyclone separator can be improved by 0.2-2.3%, and the total resistance can be reduced by about 3.0-11.0%.
