Description

The utility model relates to the field of food processing, and in particular to a device for the production of sunflower oil.

A known method of burning biomass (E.N. Saburov, S.V. Karpov. Cyclonic devices in woodworking and pulp and paper production. M: Ecology, 1993, p.77-79), implemented in a cyclone pre-furnace containing a cyclone chamber, afterburner, grate located in the cyclone chamber, and tangential nozzles. The biomass burning technology in the prototype method provides for two-stage burning of wood waste in the lower and upper combustion chambers. The crushed fuel from the hopper is fed by a hydraulic plunger through a large diameter pipe to the grate through a special hole in its center. The resulting conical pile of wood waste is ignited by a gas fired igniter, which automatically shuts off after the start of sustainable combustion of fuel. In this case, the prototype implements the classic vertical furnace design of the pre-furnace, which is convenient in that it enters the afterburner due to the action of gravity on burnt, decreasing in size, pieces of fuel.

However, in such a vertical design of the cyclone chamber and the afterburner, there are drawbacks in that when biomass is burned in such a device, it is impossible to obtain a temperature of flue gases above 850 ° C, and this in the future, when flue gases with a temperature of 850 ° C are supplied to the heat exchanger fuel oil boiler designed for 1200 ° C, leads to a decrease in efficiency

The prior art does not identify a device for waste-free production of sunflower oil, in which solid waste after peeling - husk, would be used in a power plant, which is an integral part of the entire device for providing electric / heat energy.

The technical result of the claimed utility model is to increase the efficiency power plant, namely a gas generator.

This result is achieved by the fact that in a device for waste-free production of sunflower oil containing means for feeding husk / husk granules to a gas generator based on a spiral conveyor, a flexible spiral of which is mounted to rotate in a plastic pipe located at one end in a hopper with husk / granules of husk, and the other end communicates with the feed mechanism of the gas generator, the gas generator housing consists of two detachable parts, the upper part is a cone-shaped hopper, in the upper the first part of which the feeding mechanism is mounted and installed vertically and coaxially with the combustion cone and the reactor, and the lower part of the vessel is a cylindrical reactor, while a hole is made in the wall of the reactor with a pipe for removing hot steam to generate electric / heat energy to ensure the production of sunflower oil .

Description of the technological process:

The device works with two gas generators of the WBG-500 model with purification plants. The gas produced in two WBG-500 gas generators, after appropriate preparation of the purification plants, will be used in three (3) parallel electric generators based on the Cummins GTA-1710G piston engine with a rated electric power of 220-250 kW (GPEA-250) each, operating on clean generator gas. Thus, the rated electric power will be approximately 700 kW.

Actual electrical power depends on the nature and level of vibration of the connected load.

The available thermal energy is: up to 800 kW of hot water by utilizing the heat from the cooling jackets of 3 engines (in the case of engines running at rated power);

Up to 850 kg / h steam with a pressure of 6 atm and a temperature of 160 ° C by utilizing the exhaust gases of 3 engines (in the case of engines running at rated power).

The gas generators are located in a building adjacent to the cooling and purification section of the circulating water, and consists of the following sections:

Fuel supply section for storing operational stock, delivery of husks / pellets to the hopper of the fuel supply module, and supply to gas generators.

Gasification section for obtaining clean generator gas from husks / pellets.

A power generation area for generating electric energy from a generator gas and delivering it to consumers.

A heat generation section for receiving heat carriers - hot water and steam - and distributing them to consumers.

The clarification and cooling section of circulating water for the organization of a closed circulating water system used for cooling and rough cleaning of generator gas, including circulating water regeneration modules for cleaning it from impurities that are removed from the gas and accumulate in circulating water.

For feeding husk / pellets to gas generators, spiral conveyor feed devices are used. The entire fuel supply module will consist of:

- One operational bunker,

- Two feed devices, each of which consists of a plastic pipe, inside of which a flexible spiral rotates, one end starting in the hopper, and the other end with the discharge device and the spiral drive located above the gas generator loading cone, and

- A control system that, on commands from the level sensors of gas generators, turns on and off the supply of a portion of fuel to each gas generator.

The spiral of the feed device is able to move both the husk and pellets, and the use of a flexible spiral allows the wiring of the fuel supply lines taking into account the characteristics of the room.

A reversed type gas generator is equipped with everything necessary to turn husk (pellets) into pure generator gas. The gas generator includes a feeding mechanism with one sliding sunroof and a rotary lock with automatic control installed above it, through which a husk, an isolation valve and the necessary instrumentation are loaded periodically into the gas generator.

The gas generator housing consists of two detachable parts. The upper part, called the hopper, is made of carbon steel and is a cone-shaped vessel, in the upper part of which a feeding mechanism is mounted. During operation, the hopper is removed using a crane beam or hoist for inspection and cleaning of the reactor, scraper mechanism, combustion cone, etc. It is mounted vertically and coaxially with the combustion cone and the reactor. The detachable connection of the hopper and the combustion cone, inserted from above and coaxially into the reactor, is sealed with an asbestos cord and a rubber-based sealant. Hopper and reactor flanges are bolted.

The lower part, called the reactor, is made of stainless steel and is a cylindrical vessel. The detachable connection of the reactor and the combustion cone is sealed with an asbestos cord and a rubber-based sealant. The remains of charcoal and ash are removed from the gas generator by a dry method through a special gateway and then by a water-cooled screw conveyor and two shut-off hatches into a receiving container.

Hot gas leaves the gas generator reactor through a stainless steel pipe welded to an opening in the wall of the reactor. The other end of the pipe is connected to a cyclone, from which begins the process of purification of the generator gas. Instrumentation includes temperature sensors (thermocouples), gauge differential pressure sensors and toggle switches for manual control of electrical equipment.

The generator gas purifier for the “cold clean gas” mode includes a cyclone with an ash pan for cleaning hot gas from large particles of fly ash, a Venturi scrubber that purifies gas from smaller particles and condensed resins and cools the gas, a “wet gas blower” with a separator, a heat exchanger with a gas dryer, two fine filters with a filler and one control filter with three replaceable cartridges for trapping residual fine particles of fly ash and condensed resins.

In stationary mode, the husk / pellet loaded into the gas generator turns into two products: gas and a mixture of ash and charcoal. Ash and charcoal are removed from the gas generator by a dry method through a gateway and then by a water-cooled screw conveyor to a receiving container.

The gas generator has two level sensors. The signal from the upper sensor starts the process of adding another portion of biomass. If for some reason the biomass is not added and its level in the gas generator drops to the level of the lower sensor, the emergency stop of the gas generator is activated.

The fine filter system has two parallel lines. Switching the gas supply to one of the lines is carried out automatically using pneumatic valves.

Actuators (hatches of the lock device, pneumatic valve of a gas-diesel engine, etc.) use compressed air with a pressure of 10 kg / cm3. If there is no compressed air line, the customer must use an air compressor and / or compressed air cylinders.
