Abstract

The invention relates to the technique of ventilation and air conditioning, mainly from plastic shipbuilding shops and other similar industries. The aim of the invention is to reduce energy costs and reduce the emission of harmful gases into the atmosphere. The recirculated air from the workshop is fed by the fan 5 to the filter 18, and then to the purifier 6 harmful gases, which are made as modules of nuclear membranes forming alternating cross-directed flow chambers of the two directions, with the chambers of the same direction being connected to the supply duct 1 and device 7 afterburning of harmful gases, and chambers of a different direction are connected to the recirculation duct 2 and coil 9 located in device 7 afterburning of harmful gases. The cleaned and heated recirculated air is supplied by the fan 4 to the workshop, and the combustion products from the afterburner 7 are released into the atmosphere. 2 yl

The invention relates to a technique for the ventilation and air conditioning of mainly plastics shipbuilding and other similar plants with the emission of harmful vapors and volatile substances.

The purpose of the invention is to reduce energy costs and reduce the emission of harmful gases into the atmosphere.

FIG. 1 is a diagram of an air conditioning system; in fig. 2 - recirculated air cleaner made in the form of a module of nuclear membranes.

The air conditioning system, for example, the plastic shipbuilding plant contains a supply air duct 1 of atmospheric air and a recirculation air duct 2 with fans 3, 4, 5 installed on the air ducts, a cleaner 6 of recirculated air from harmful gases communicated with the atmosphere, a device 7 afterburning of harmful gases and check valves 8.

The device 7 afterburning of harmful gases is made in the form of a heat utilizer with a coil 9 placed inside, connected inlet and outlet to the recirculation duct 2 parallel to the latter, and equipped with a nozzle 10 from the gas line 11, and recirculating air purifier 6 made in module 12 of nuclear membranes 13, which form alternating cross-directed flow chambers 14 and 15 of two directions, while chambers 14 of one direction are connected by an inlet to the supply duct 1 of atmospheric air and outlet - 7 afterburning apparatus harmful gases, and another camera 15 connected to an input directing a recirculation duct 2, and the output - to the coil 9 of the device 7 afterburning.

In addition, a shut-off device 16 is placed on the gas line 11, and a heater 17 and an air filter 18 are installed on the recirculation duct.

The air conditioning system operates as follows.

From the lower part of the workshop, air is removed through the recirculation duct 2 by the fan 5, which supplies the contaminated air first to filter 18 and then to recirculating air purifier 6.

The recirculated air cleaner 6 is a module of nuclear membranes 13 that allow carbon dioxide, styrene and other harmful volatiles to pass in one direction. The nuclear membranes 13 form cross-flow chambers 14 and 15. Recirculated air passes through chambers 14, and atmospheric air flows through chambers 15, which is supplied through the supply duct 1 by fan 3. Carbon dioxide, styrene and other harmful volatile substances pass through the oil membranes t

from the recirculated air to the chambers 15, and then through the air duct 1 to the device 7 afterburning of harmful gases. In the device 7, the afterburning of harmful gases is effected by means of gas supplied through the gas line 11 through the nozzle 10. The gas is disconnected from the gas line 11 by the switching off device 16.

In this way, the recycle air is cleaned of harmful gases. From device 7 afterburning of harmful gases, the combustion products are emitted into the atmosphere. In the device 7 afterburning of harmful gases through the coil 9, the heat of the combustible gases is transferred to recirculated air, which passes inside the coil 9. After heating in the coil 9, the recirculated air is fed by the fan 4 to the workshop. In this case, heating of recirculated air in oxygen can be performed 17.

The recirculated air, if necessary, can be sent to the workshop, mine device 7 afterburning of harmful gases. To this end, shut-off valves are installed in the recirculated air duct. The proposed air conditioning system reduces the heat consumption for heating the air by burning harmful gases generated in the workshop and, in addition, reduces harmful emissions into the atmosphere.
