Abstract

The invention relates to the production of thermally expanded graphite used as a sorbing agent for cleaning water and soil contaminated by petroleum products. A formed two-phase flow of particles of oxidised graphite powder and a vector gas is supplied to a heating area and afterwards to a decompression area. Simultaneously, said flow is cooled by a flow of dissolving gas which is supplied in the direction of the two-phase flow. The thus produced expanded graphite is transported to a storage tank. The two-phase flow is mixed with a riser flow of a heated working gas upon entry into the heating area, a volume ratio between the two-phase flow and the working gas flow is maintained within a range of 1:7-1:150. The inventive device for producing a carbon sorbing agent comprises a feeder, a pipe for delivering the oxidised graphite with the vector gas to a heating chamber, a nozzle for the dissolving gas arranged at the exit from the heating chamber, a decompression chamber, a storage tank for the sorbent, a porous diaphragm and a pipe for evacuating associated gases. Said device also comprises a delivery line for the working gas and a heat recuperator. The pipe for delivering the working gas is provided with a flow energiser and is arranged at the entrance to the heating chamber. The heat recuperator is mounted on the delivering line for the working gas outside the heating chamber. Said invention makes it possible to improve the productivity of the method, the quality of the sorbent based on the thermally expanded graphite, the reliability of the device, to simplify the construction design thereof and to reduce energy consumption.

Description

SPΟSΟB AND USΤΑΗΟΒΚΑ FOR PREPARING ANGLE

The area of technology The invention is not available for use on the base of the thermal system;

Prevailing level

The method of HNG production is known, including the mixing of an acidic gas mixture with a gas carrier, the mixture being fed in a heating chamber, and the next process is turned on to the receiver. There is a known installation for the supply of this equipment, which contains a power supply, a pipe for supplying an oxidized gas heater and a household chimney.

The disadvantages of the well-known solutions are the low productivity and unavailability of its regulation, as well as the uncomplicated installation.

The means and installation are known for the receipt of gas (patent No. 2134657, 1998). Sπο- sοb πρedusmaτρivaeτ φορmiροvanie dvuχφaznοgο ποτοκa chasτits ποροshκa οκislennοgο gρaφiτa and gas-nοsiτelya, ποdachu ποτοκa in zοnu nagρeva and zaτem in zοnu ρazρezheniya with πο- following οτvοdοm ποluchennοgο ρasshiρennοgο gρaφiτa. The unit is supplied with food, the unit is supplied with an oxidized gas with a gas carrier, the unit is heated and the unit is heated.

The speed of delivery of a two-phase flow to the heater selects such, which ensures a ring-shaped flow regime. With this, partly depleted unit is expanded only in the industrial area of the heating unit, where the necessary heat is generated. In general, the productivity of the installation is limited to the area of the convenience of the heater. In order to create a ring mode of flow, it is necessary to provide a larger amount of carrier gas, which will lead to a decrease in the efficiency of the energy due to the increase in the energy consumption.

The method and device closest to what is claimed is described in the patent of the School of Law No. 2102315 on “Installation for receiving a charge”, 1996.

The waste of a well-known technical solution is a complex appliance, high energy consumption, and low power consumption.

SUMMARY OF THE INVENTION

The proposed invention is designed to increase the profitability of the product, since it is our best advantage to receive a share of the service, and it is reliable to install it.

When this is done, the gas treatment unit is equipped with a waste gas boiler, it is installed at the inlet to the heating chamber, and the gas inlet is turned on The delivery line for the gas can be equipped with a burner with a differential adjustable capacity

At the end of the set-up, a ver- tical good concession is established, dividing the camera into two adjacent spaces, which are shared between themselves in the nurse. The quick disconnect is located in the upper part of the chamber of the discharge chamber for removal of the associated gases. The bottom of the chamber is made in the form of a military unit from a gas-based material. On the lower part of the heating chamber, a manhole for removing ash and non-reacted particles of an acidified furnace is allowed. The proprietary cartridge is installed in front of the camera.

Β In a known manner, the oxidized gas burner is supplied with a gaseous carrier through a chimney connected to it and it is not necessary to charge the heater.

The latter is supplied in the lower part of the heating chamber through the turbulence, which creates a risk of overpressure and a significant reduction in pressure from this.

Particularly lowered pressure zone is partially introduced by acidified particles.

Β As a result of the loss of already expanding particles, the screen is also converted to the available parti- cles of the accelerated gas flow from the hot gas. 4

Β Heated chamber declared installation, in contrast to the known devices, the concentration of the interconnecting connections is much less, due to the disconnection of the gas The volume units are 1: (7-150). Thanks to this, the large size of the unit is increasing.

Range 1: (7-150) is selected taking into account the distribution of raw materials (an oxidized group) for the observance of an unacceptable food product. With an increase of more than 1: 150, it increases for working gas. This results in an increase in the temperature of the exhaust gas and by-products at the outlet of the heating chamber and from the increased consumption of gas. In addition, a decrease in the profit of a two-way business results in a decrease in the profitability and an increase in the profitability of the consumer due to the increase in the blackout

This makes it possible to exclude the purchase of a channel for the exit of the customer due to the profitability of the company. At first, the flow of the chamber pressure is further increased due to the large pressure drop in the flow. With this, the concentration of the flue gas is reduced even more, and at the same time there are no gas bells.

The increase in the lower part of the chamber in the form of a separate product from the gas, gas and gas is very costly, as a result it minimizes the risk of loss of energy to the whole world. This ensures that the battery is equally filled with proprietary. Уль As a result, the pressurized gas inlet, in the upper part of the discharge chamber, is not obscured, there are no This increases the reliability of the installation.

To remove sludge, ash and non-reactive particles of acidified material in the bottom of the heating chamber, hatch 18 is allowed.

The installation for the implementation of the declared method operates the following way. Dry oxidized gas is loaded into the bunker 1. By the way, 2 of the source of the compressed gas feeds the carrier gas.

* The working gas stream is measured at the entrance to the unit after the compressor.

In general, the primary source of the expansion of the oxidized gas is the gas treatment unit. The expansion chamber of the chamber is used to expand the already prepared group and burn out the serial connections. With a constant temperature of the working gas, but an increase in its consumption, the cost of finished product is improved (the bulk density of the sorbent is reduced). But, at the same time, an increase in the flow rate of working gas by 25% (Examples 1 and 6, 3 and 7), a decrease in the net income is 15–20% ”. With a constant flow of working gas, but an increase in its temperature, the quality of finished products improves. However, with a change in temperature by 11% (Examples 1 and 10, W and P), our payroll changes by 27%.
