Abstract
The utility model discloses a waste gas recycling device which comprises a waste gas collection pipe. The waste gas collection pipe is communicated with the water inlet of a bent heating pipe arranged under the water surface in a boiler, and the water outlet of the bent heating pipe is extended out of the boiler. By means of the structure, the waste gas recycling device has the advantages that 1, exhausted waste gas enters the heating pipe through the waste gas collection pipe to heat cold water in the boiler, waster gas heat energy is prevented from being wasted, and recycling of waste gas is achieved; 2, fuel is saved, and production cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of waste gas recycle device.
Background technology
In the production process of autoclaved aerated block, produce a large amount of toxic emissions, toxic emission, not only to environment, after the waste gas of high temperature is drained simultaneously, causes a large amount of thermal waste.And need to use boiler to heat cold water in producing, need to use a large amount of fuel.
The utility model content
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, to provide a kind of waste gas recycle device of avoiding the heat energy from waste gas waste.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of waste gas recycle device, comprise the gas sampling pipe, described gas sampling pipe is communicated with the water inlet that is placed in the crooked heating tube below the water surface in boiler, and the delivery port of described heating tube extends outside boiler.
The delivery port of described heating tube is provided with control valve.
Described heating tube is the wave bending.
Described heating tube is metal tube, and its outer wall surface is provided with zinc coat.
The utility model adopts said structure, has the following advantages: 1, the waste gas of discharge enters heating tube by the gas sampling pipe, and cold water in boiler is heated, and avoids the heat energy from waste gas waste, realizes the waste gas recycling; 2, saved fuel, significantly reduced production costs.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is structural representation of the present utility model;
In Fig. 1,1, the gas sampling pipe; 2, boiler; 3, heating tube; 4, control valve.
The specific embodiment
A kind of waste gas recycle device, comprise gas sampling pipe 1 as shown in Figure 1, and gas sampling pipe 1 is communicated with the water inlet that is placed in the following crooked heating tube 3 of the interior water surface of boiler 2, and the delivery port of heating tube 3 extends outside boiler 2.The delivery port of heating tube 3 is provided with control valve 4.Heating tube 3 is the wave bending.Heating tube 3 is metal tube, and its outer wall surface is provided with zinc coat, prevents from getting rusty, and inner wall of metal tube also is provided with corrosion-resistant coating, prevents that the high temperature of waste gas is by the inner wall corrosion of heating tube.
In the production of autoclaved aerated block, produce a large amount of toxic emissions, the waste gas of discharge enters heating tube 3 by gas sampling pipe 1, by the heat transmission, cold water in boiler 2 is heated, and avoids the thermal waste of waste gas, realizes the waste gas recycling.Saved fuel, significantly reduced production costs.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
