Abstract

The utility model pertains to the technical field of fuel gas and relates to the technology of a gas water-heating boiler. A modular gas water heater is provided. Wherein, a gas water heater of constant power is taken as one module. Two or three such modules form a modular gas water heater. A plurality of modular gas water heaters form gas water heaters of different powers. The utility model solves the problem that gas boilers of different powers can't be produced in massive way, are of high cost, and difficult to install. The modular gas water heater herein is compact, light, of high thermal efficiency, low cost, short manufacturing period and can achieve massive production.

Description

Modular gas and hot water unit

Technical field

The utility model belongs to the gas technology field, and it is particularly related to the gas-fired water heating boiler technology.

Background technology

As everyone knows, existing gas-fired water heating boiler is that a combustor is contained on the metal body of heater, the gas fired-boiler combustor difference of different capacity, and body of heater varies in size, existing gas-fired water heating boiler production can only single-piece production, and the production cycle is long, and the welding job amount is big, material usage is big, the cost height, and volume is big.The body of heater of existing gas-fired water heating boiler is to be welded into steel plate, and body of heater gets rusty easily, and long body of heater of time is corroded easily and wears.Because the body of existing gas-fired water heating boiler is big, carrying, installation are all difficult, will could install with crane when particularly being installed in roof.

Summary of the invention

Shortcoming present situation in view of existing gas-fired water heating boiler existence, it is little that the purpose of the utility model patent provides a kind of volume, energy-efficient modular gas and hot water unit, adopt the utility model modular gas and hot water unit, have that cost is low, the thermal efficiency is high, volume is little, make the single-piece production of boiler become batch process, carrying, easy for installation, characteristics such as be difficult for getting rusty.

For realizing having reached purpose of design, the utility model adopts following structure, mainly comprise anti-blast cap (1), smoke extraction chamber (2), water inlet pipe (3), outlet pipe (4), air inlet pipe (5), controller (6), heat exchanger (7), combustion chamber (8), burner (9), air valve (10), frame (11), compress switch (12), automatic exhaust steam valve (13).Heat exchanger (7), combustion chamber (8), burner (9) are designed to decide the standard heating module of power, and 2-3 the standard heating module of deciding power formed a gas and hot water unit, and several gas and hot water units can and be unified into more powerful gas and hot water unit.

Description of drawings

Accompanying drawing is the structural representation of modular gas and hot water unit, (1) be that anti-blast cap, (2) are that smoke extraction chamber, (3) are that water inlet pipe, (4) are outlet pipes, (5) be that air inlet pipe, (6) are that controller, (7) are that heat exchanger, (8) are that combustion chamber, (9) are that burner, (10) are that air valve, (11) are that frame, (12) are pressure switches, (13) are automatic exhaust steam valves.

The specific embodiment

The utility model is by anti-blast cap (1), smoke extraction chamber (2), water inlet pipe (3), outlet pipe (4), air inlet pipe (5), controller (6), heat exchanger (7), combustion chamber (8), burner (9), air valve (10), frame (11), compress switch (12), automatic exhaust steam valve (13) is formed.Earlier water inlet pipe (3) is connected with circulating-pump outlet during work, inlet of circulating pump is connected with attemperater, temperature sensor is contained in the water inlet, outlet pipe (4) is connected with attemperater, air inlet pipe (5) links to each other with gas pipeline, attemperater is piled water, open air valve, connect power supply, circulating pump and the work of modular gas and hot water unit, circulating pump extracts the water in the attemperater through modular gas and hot water unit Fast Heating out, return attemperater, water is heated, and water heats through circulation after a while, water temperature in the attemperater reaches the temperature that sets, controller (6) control module formula gas and hot water unit, circulating pump quits work, and when coolant-temperature gage dropped to the operating temperature that sets, modular gas and hot water unit and circulating pump be task again, repeat above process, whole process is controlled automatically by controller (6) and is finished.

The utility model is designed to a heating module of deciding power with nonstorage calorifier, and the 2-3 heating module also is connected into a modular hot water unit, and several modular hot water units also are connected into more powerful hot water unit.

In sum, the utility model provides a kind of Modular type gas hot-water unit to have efficient, energy-conservation, one-tenth This is low, and carrying, easy for installation makes the single-piece production of boiler become the characteristics such as batch production.

Claims (1)

1, a kind of modular gas and hot water unit, it comprises anti-blast cap (1), smoke extraction chamber (2), water inlet pipe (3), outlet pipe (4), air inlet pipe (5), controller (6), heat exchanger (7), combustion chamber (8), burner (9), air valve (10), frame (11), pressure switch (12), automatic exhaust steam valve (13), it is characterized in that heat exchanger (7), combustion chamber (8), burner (9) air valve (10) are connected as a single entity becomes a standard gas and hot water heating module.
