Description

The utility model relates to an air heating system designed for air heating and ventilation of easily assembled individual shelters of a gas pumping unit (GPA) with the provision of:

- prerequisite conditions for the gas compressor unit;

- sanitary and hygienic working conditions for GPA service personnel during routine maintenance.

From the patent RU 100196 U1, selected as the closest analogue, a gas model gas heating unit is known. The known unit relates to air heating systems, in particular to systems using gas air heaters, can be used for autonomous air heating of buildings and structures. The unit according to the first embodiment contains a box-type prefabricated case, fans, an automatic control system, an air intake unit installed at the inlet, a heating unit and a collector. The unit also contains the main and backup fans located in the air intake unit, between the air intake unit and the heating unit with recuperative air heaters, a distribution unit is installed. The unit according to the second embodiment contains a box-type prefabricated case, fans, an automatic control system, an air intake unit installed at the inlet, a heating unit, and a collector. The unit also contains the main and backup fans located in the air intake unit and the heating unit with recuperative air heaters. The utility model allows to increase the operational characteristics and energy efficiency of the device.

A disadvantage of the known utility model is that it excludes the possibility of repairing a failed main fan during operation of the backup fan and vice versa, due to the fact that the equipment is located in the intake unit.

The technical result of the claimed utility model is that the maintainability characteristics of the system are increased and the possibility of combustion products entering the air supplied to the shelter is excluded.

The claimed technical result is achieved by the fact that a ventilation and heating system is proposed, including an air intake chamber, main and backup fan blocks, main and backup heat generator blocks mounted in a block box, characterized in that the main fan block is independent of the backup fan block, block the main heat generator is made independent of the backup heat generator block, and the fan blocks are installed up to the heat generator blocks, installed outside the block box elements of the exhaust system.

Figure 1 presents the inventive ventilation and heating system (CBO), where:

1 - Block box;

2 - Air intake chamber;

3 - Block of the main fan;

4 - Reserve fan unit

5 - The block of the main heat generator, consisting of a combustion chamber and a heat exchange unit;

6 - Burners of the main heat generator block;

7 - Block backup heat generator, consisting of a combustion chamber and a heat exchange unit;

8 - Burners of the main heat generator block;

9 - Duct system (within the CBO block box);

10 - Fuel gas supply system;

11 - exhaust system;

12 - Condensate neutralizer;

13 - Pump installation for condensate discharge;

14 - Elements of the heating and ventilation system of the block box;

15 - Cabinet automatic control system (ACS) and low-voltage complete device (GCC);

16 - System for technical control of fuel consumption;

17 - The system of working and emergency lighting block box.

18 - Elements of a fire alarm system and methane gas pollution control.

The ventilation and heating system (Figure 1) consists of the main elements - blocks of the main and backup fans and blocks of the main and backup heat generators with air heaters, which are installed in the block box with the rest of the equipment, and additionally exhaust system elements are mounted outside the block box.

The block box and exhaust system are installed on the foundation.

The operation of the claimed device is as follows. External air through the intake chamber 2 is sucked in by the main 3 or backup 4 fan unit and supplied externally to the combustion chamber and heat exchanger located inside the main 5 or backup 7 heat generator unit. Fuel is supplied by the fuel gas supply system 10 to the burners of the main 6 or backup 8 heat generator. The burners, mixing fuel with the required amount of air, feed this mixture into the combustion chamber of the main 5 or backup 7 heat generator. The combustion products pass through the heat exchanger of the main 5 or backup 7 of the heat generator and heat the air, which blows the heat exchanger. Heated air through the duct system 9 is supplied to the supply ventilation system of the shelter, and the exhaust gases through the flues of the exhaust system 11 are discharged to the outside.

The temperature of heating the air supplied to the shelter in the automatic mode is controlled by an automatic control system (ACS).

The main functions of self-propelled guns:

- Ensuring the operation of the water cooling system in a continuous mode without constant maintenance

- execution in automatic mode of start-up, automatic ignition, maintenance of a predetermined mode of operation and shutdown of the water cooling system, with fixing the signals that caused the shutdown;

- automatic protection by technological parameters;

- Presentation of information on the operating mode and condition of the air-conditioning system;

- maintaining the temperature in the shelter at the required level;

- management of ventilation and heating systems of the CBO block box;

- technical accounting of fuel gas;

- automatic transition from the main to the standby heat exchange module;

- interaction with top-level self-propelled guns via an information communication channel.

The main functions of the NKU

- reception and distribution of electricity;

- switching power circuits of power consumers with their automatic or manual control;

- protection of power circuits and electric motors from short circuits and overloads;

- providing the possibility of manual control of mechanisms;

- formation and transmission to ACS of the status signals of power receivers (on-off, open-closed) and the signal readiness of the switchgear to work in automatic control from the ACS;

- light indication of the status of power receivers (on-off, open-closed).

Thus, the inventive utility model eliminates the possibility of ingress of combustion products into the air supplied to the shelter, due to the fact that the excess air pressure supplied by the fan from the outside to the combustion chamber and heat exchanger located inside the main or backup heat generator unit is higher than the pressure of the gas-air mixture and the exhaust pressure gases moving inside the combustion chamber and heat exchanger of the heat generator unit. The maintainability characteristics of the system are improved due to the fact that during the repair of the main fan and the main heat generator, the operation of the backup fan and the reserve heat generator is allowed.
