Description

HEAT MODULE (TWO OPTIONS)

The inventive variants of the utility model relate to installations for providing heat to heating systems, ventilation, hot water supply and technological heat supply with a nominal heat output of 0.5 to 10.0 MW, running on natural gas of low, medium or high pressure and (or) light (light), as well as dark (heavy) grades of oil products.

Well-known heat supply installations in the form of boiler plants, consisting of a set of devices and designed to produce hot water under pressure (see, for example, the Great Soviet Encyclopedia). Boiler installations (hereinafter boiler / boiler room), located in separate buildings and / or built-in rooms, are a combination of a boiler, burner and auxiliary equipment located throughout the entire area of the premises used. The boiler house, in addition to the boiler and burner, may include: blowing devices, gas and air pipes, water and fuel pipelines, valves, automation, control and protection devices and devices, as well as water treatment equipment and a chimney related to the boiler.

The construction of any stationary boiler room is fraught with a number of difficulties, which the construction and installation organization has to overcome. Often, the difficulty lies in organizing and coordinating the construction of the boiler house, the selection and delivery of technological equipment, and its installation inside the newly built building. Carrying out this type of work requires significant time and material costs. the disadvantages are multiplied by the need to build a boiler room in remote and inaccessible areas, as a rule, not having developed infrastructure and / or not able to provide the proper level of organization of construction and installation works.

Given these shortcomings in the construction of boiler plants, block-modular boiler plants were developed and introduced, the design of which allows them to be transported by all known means of transport and used for heating and hot water supply of household and household objects. These units include block boiler plants of the BKU series (see the website http: //gazovik-gaz.sh/catalogue/tku/001/), proposed as the closest analogue. Known installations are designed to generate hot water, used as a coolant in heating systems and hot water for facilities for various purposes. The arrangement of known installations includes a boiler, a burner, a feed pump, a water treatment device and a WATER installed in a transportable container.

The disadvantages of both the described modular installation and other analogues of such installations include the need for the presence of maintenance personnel in the workspace of the installation during its operation for the purpose of prevention and repair of equipment, which significantly reduces the safety of such operation.

In view of the foregoing, the author of the claimed variants of the utility model posed the task of creating a modular installation heat supply, devoid of these disadvantages inherent in known modular installations.

The achieved technical result in the implementation of the claimed variants of the utility model is to increase the safety of operation of modular heat supply units, their versatility, compactness and mobility.

To implement this result, two options are proposed for a compact heat supply installation made in the form of a module and containing at least one hot water boiler, at least one burner and at least one circulation pump installed with the possibility of interaction. Both installation options provide for the installation of all equipment on a portable support-bearing frame from the condition of close proximity of the equipment elements from each other and access to the working bodies of the elements around the perimeter of the module. The difference between the second option and the first is the presence of the lining of the supporting frame with a protective casing.

Preferably, both embodiments may comprise auxiliary equipment in the form of at least one of the following elements: pressure maintenance equipment in the heat supply system, equipment for the hot water supply system, including heat exchange equipment, fuel metering equipment, heat metering equipment, feed water treatment equipment, control cabinet and power equipment, made with the possibility of interaction with elements of the boiler room.

The protective casing according to the second installation option can be equipped with removable panels and / or opening hatches. The utility model is illustrated by images of general views of the first - Fig. L and the second - Fig. 2 options.

In general terms, the claimed variants of the utility model consist of a set of main and auxiliary equipment. The structural composition of the elements of the main equipment is generally known in general, since it is determined by the general requirements for the composition of any boiler plants. These elements include a hot water boiler 1, a burner 2 and a circulation pump 3, which connects the corresponding elements to the piping piping with shut-off and control valves, as well as equipment for control and safety systems. The number of listed elements, their technical characteristics, type of burner supply (natural gas or liquid fuel) can be different and determined both by the initial operating conditions of the installation and the required amount of heat released.

As auxiliary equipment, the claimed variants of the utility model can be equipped, if necessary, with equipment for maintaining pressure in the heat supply system 4, hot water supply equipment (including heat exchange equipment), means of metering fuel consumption and thermal energy, equipment for preparing feed water, etc.

A distinctive feature of both declared variants of the utility model from the existing elements of any of the boiler houses is their modular design, which is ensured by the compact placement of the main and auxiliary equipment on a single support-bearing frame (platform) in close proximity to each other. For greater compactness, the distance between technological equipment does not exceed the minimum possible necessary to ensure general safety requirements, and the space between the equipment is used only for the location of the piping. It should also be noted that to simplify access to the equipment of the installation during its operation (for repair, maintenance, maintenance, etc.), the casing according to the second embodiment can be equipped with removable panels and / or opening hatches. Essentially, the declared variants are a mobile thermal module, completely ready for operation, assembled “under the key” at the manufacturer, which can be used both as an independent heat supply unit and as a part of a boiler room. The preparation of a thermal module for operation essentially involves only its placement in the required place with its subsequent connection to the piping systems, as well as to the power supply and safety systems. The foregoing, with all the obviousness, allows us to conclude that the claimed variants of the utility model are significant advantages, since the modular design combined with the compact placement of technological equipment can significantly reduce the requirements for the size of the space allocated for boiler rooms. Moreover, the second version of the thermal module (with a protective casing) essentially makes it possible to place it in the open air, without requiring the presence or construction of special rooms. Among the advantages of the compact design of the thermal module should also be attributed to the fact that during its operation the presence of service personnel in the spaces between the technological equipment is impossible, which, in turn, ensures an increase in the level of labor safety during operation of the module.

Access to the technological equipment of the thermal module during operation is carried out exclusively along the perimeter of the module, which makes it possible to carry out repairs and scheduled maintenance.

In conclusion, it should be noted that the claimed model, if necessary to use it as part of stationary boiler plants, guarantees a reduction in the cost of organizing and performing construction and installation works, which undoubtedly is its additional advantage.

The declared thermal modules can find independent application or use in boiler houses, subdivided according to their purpose into:

• heating - to provide heat for heating, ventilation and hot water systems;

• heating and production - to provide heat for heating, ventilation, hot water supply and for technological heat supply;

• production - for technological heat supply.
