Description

The modifier feed device is designed for continuous input in a predetermined ratio of fluid (liquid) means - additives to intensify combustion in gaseous and liquid hydrocarbon fuels. Such an injection can be carried out, in particular, in gaseous fuel - natural gas, by ensuring the continuous introduction of a automatically measured ("dosed") given amount of fluid - a modifier for the intensification of homogeneous combustion, for example. into the air (oxygen) stream, directly to the device (burner, nozzle) for mixing with fuel, with the aim of subsequently supplying an aggregate mixture of an ordered structure to the burner outlet, spraying and burning the mixture with the formation of a stable combustion front.

A device for dispensing fuel into a combustion chamber is known, comprising a control chamber of a predetermined volume, an injection chamber directly communicating with a control chamber and adapted for charging with compressed gas during use, means for injecting a predetermined amount of fuel into a control chamber in each cycle of a combustion and displacement chamber fuel from it to the injection chamber and thereby replenishing the control chamber, having means for removing fuel from the control chamber, deis for at least part of the range of the engine’s working load to determine the amount of fuel that can be displaced from the control chamber into the injection chamber to be injected into the combustion chamber the next time the control chamber is filled and means for controlling means for injecting fuel into the control chamber in depending on the need of the engine to change the amount of injected fuel, while the means of injecting fuel into the control chamber is an adjustable pressure pump [Patent RF №2102619 for the invention "A method of dispensing fuel, a device for its implementation, a method for dispensing fluid means and a device for its implementation", publ. 01/20/1998, IPC G01F 11/28, G01F 11/32, G01F 11/38, G01F 11/44, G01F 13/00]. The disadvantages of such a device include a certain complexity of the design and discreteness of injection, if necessary, to ensure a continuously-continuous supply of fluid in a given volume (quantity).

Similar metering devices are known for introducing fluid means, in particular odorants, into the fuel gas. For example, structurally identical gas odorization unit (utility model) and modular type odorizer (invention), containing, each device, fluid containers - odorization, flow and volumetric, vacuum pump connected to the flow capacity and breathing line, metering pump, breathing filter, manovacuum meter, fluid level sensor, fluid flow measuring unit, fluid inlet to gas flow unit, as well as a control unit equipped with a pressure sensor for monitoring fluid metering and a vacuum sensor, while the fluid metering metering unit is of an automatic type and contains a measuring tank connected to an electromagnetic valve and a differential pressure gauge, the metering pump is made of an asynchronous type with a built-in number of strokes sensor [RF Patent No. 69232 on utility model "Gas odor installation", publ. 12/10/2007, IPC G01F 11/00 and RF patent No. 2362127 for the invention of “Odorizer of the modular type”, publ. 07/20/2009, G01F 13/00, F17D 3/11]. This device uses a stepwise complicated filling scheme - refueling a consumable container using additional technical means - a vacuum pump and a breathing line, there is a discreteness of fluid input (odorant).

A similar device for supplying and regulating the flow of fluid (odorant) is known, comprising a flow meter for installation on a gas pipeline, a flow tank with a fluid, a piston metering pump with suction and discharge lines, inlet and outlet valves, and a discharge line connected to consumable metering containers for connecting to a gas pipeline, a suction line connected to a cavity of a container filled with (liquid) fluid, a drive and control system for a metering pump, while a piston pump the mash is located inside the supply tank having a top cover, and the drive is outside the tank, and the hole in the top cover through which the piston metering pump rod passes is equipped with a seal, or a bellows is sealed in the cover on the inside of the tank, to which is fixed on top the actuator rod, and below the rod of the piston metering pump [RF Patent No. 2361180 for the invention "Device for supplying and regulating the flow of odorant (options)", publ. July 10, 2009, IPC G01F 13/00, G05D 7/00]. This device also has a complicated arrangement that requires additional sealing of the moving parts of the drive, which are also located directly in the supply tank, that is, in the environment of a foul-smelling odorant, and a drip fluid inlet that does not provide a continuous supply of fluid in a given volume (quantity) .

As a prototype for a modifier supply device, a natural gas odorization device is adopted comprising a storage container for a fluid (liquid) medium, a supply container, a dispenser, a fluid level sensor, a pressure sensor, shut-off elements and a control unit, the fluid storage tank and the supply tank having pressure sensors, connected by a pipeline to a pump sequentially located on it and a locking element in the form of an electrically controlled ball valve, the supply tank is equipped with a differential pressure sensor It is used to measure the level of the fluid and is connected by a second pipeline to the gas line through a second electrically controlled ball valve and a dispenser made in the form of a peristaltic pump, while the supply tank is connected to the gas pipeline by a gas pipeline using a third electrically controlled ball valve, and the supply tank is connected to the tank storage by the second gas pipeline by means of a fourth electrically controlled ball valve having the ability to communicate with the atmosphere through an electrically controlled valve and filter p-deodorizer, while pressure sensors and a differential pressure sensor are connected to the input of the control unit, and pumps and electrically operated taps to the output of the control unit [RF Patent No. 2457445 for the invention, “Method for automatic odorization of natural gas and a device for its implementation”, publ. July 27, IPC IPC G01F 13/00, G05D 11/02]. To some extent, such a device is difficult to maintain and ensure reliability, some of the devices operate under pressure and directly in a natural gas environment, which is also used in an odorant control system to maintain operating pressure with an additional connection to the gas main, peristaltic the pump gives out a pulsating - portioned supply of fluid.

The problem to which the proposed utility model is aimed is to create a reliable and easy-to-maintain device for continuously introducing a given amount (volume or mass) of a fluid — a modifier of intensification of combustion in hydrocarbon fuel, in particular for supplying it to air (oxygen) during the formation of a mixture of air with fuel directed to the burner outlet and burning it with the formation of a stable combustion front, as well as taking into account the flow rate and preventing loss of the modifier.

The technical result is achieved by the fact that in the device for supplying and regulating the flow rate of the modifier, which contains a consumable container for storing a fluid (liquid) medium - a modifier equipped with an injection pump with a meter for recording the volume of injection, a level sensor and a metering and metering unit for consumption, a filter sump and a common fine filter at the outlet of the supply tank, discharge unit, including one or more adjustable feed pumps with pressure sensors, corresponding manifolds with check valves, having adjacent technological outlet lines for the sectional supply to the burner, including the supply units, each containing, in series, a pressure sensor, a fine filter, a needle valve, a connection to the fastening of the supply unit on the main (air pipeline), the tip of the feed-spray line, in which the assembly itself is located - a folding nozzle-sprayer, including a calibrated nozzle-tube, a terminal sprayer in a protective casing, seals (washers, pressure rings) and clamping fasteners.

The inventive utility model is illustrated with the help of the drawings, which schematically show examples of the general principle layout of the continuous feed modifier installation (Fig. 1) and the general principal view of the spray feed-injection modifier assembly (Fig. 2). The diagram, as an example of execution, shows two adjustable supply pumps and the corresponding two distribution manifolds on three supply lines each. In the drawings, positions 1-25 indicate:

1 - injection pump;

2 - injection meter;

3 - consumable capacity;

22 ... 24 - locking elements;

The main elements are made of stainless steel. The size of the supply capacity is consistent with the flow rate of fuel supplied to the burner.

The modifier supply device, designed for continuous input in a predetermined ratio of fluid (liquid) means - additives to intensify combustion in gaseous hydrocarbon fuel, works as follows. To bring the device to its original operating state, after connecting the power supply and control system, the fluid of the combustion modifier by the injection pump 1 is fed into the supply tank 3 through the meter for recording the injection 2, while the filling of the tank 3 and the operation of the pump 1 are regulated by a level 4 sensor-signaling device. From the supply tank 3 through the filter sump 6 and the fine filter 7, an electrically controlled adjustable feed pump 8, equipped with an electrocontact pressure sensor 9, through the check valve 10, the fluid medium directed into a collector 11 and further directly to the feed-injection unit 12. The calculated amount of feed inoculant depending on the type of fuel and the volume (amount) determined from empirical relationships:

for gaseous fuels, the supply volume is q _i → k _i Q _i ,

where q _i is the modifier volume, ml;

k _i is the empirical coefficient (for natural gas (methane) k = 0.01;

Q _i is the volume of gaseous fuel, m ³ ;

i - type of fuel,

for liquid fuel, the amount of supply, g, is m _i → l _i M _i ,

where l _i is the corresponding empirical coefficient of order l _i = 0.014.

At the same time, to supply the modifier as a pump, you can use a laboratory liquid dispenser with the following features: automatic volume formation (with electric drive), single-channel, with variable volume change, without an air gap between the liquid and the dosing unit. To control and regulate the supply volume of the modifier, a flow measuring and metering unit 5 is installed on the supply capacity 3 and calibrated depending on the size of this capacity. Before injection directly into the air pipe 25, upon exiting the manifold 11 through the shut-off element 24, the fluid directed to the injection-injection unit 12 passes a fine filter 14, where the shut-off needle valve is finally freed from possible small mechanical and other foreign inclusions 15, used, if necessary, to regulate the pressure measured by the pressure sensor to control the dosing and supply of fluid 13, and is sent to the spray nozzle 17, fixed by means of a flange connection 16 on the wall of the pipe 25, placed coaxially directly inside the air pipe 25 in such a way that the injection is carried out in the direction of the air directed into the burner for mixing with the fuel. In this case, the collapsible nozzle-sprayer 17 contains a calibrated nozzle-tube 18 of strictly specified internal diameter and length, ensuring the continuity of the jet of continuous advancement of the estimated amount of supply of the modifier, depending on the type of fuel and its volume (quantity) and calculated from empirical ratios, the terminal atomizer in a protective casing-swirl 19, the constituent elements are structurally assembled in a collapsible nozzle-atomizer 17 using rubber, fluoroplastic and metal allical gaskets and seals 20 and mechanical fasteners 21.

A real prototype of the described device under the name "Automated Modifier Supply System (AFM)", having a working volume of the supply capacity of 230 l, two pumps of adjustable flow with a control range up to 1 l / h and a calibrated tube with a given diameter of 0.13 mm, is mobile complex, explosion-proof and electrical safety mounted on wheels, with the ability to quickly move to connect to the location of the duct and gas burner of the boiler plant. The device is simple and reliable in operation, provides a continuous supply of fluid for atomization and mixing in a precisely defined small volume (quantity), which is typical for the use of a modifier of intensification of fuel combustion by forming an aggregate mixture in the fuel of an ordered structure that ensures effective speed and completeness of combustion and the formation of a stable combustion front.
