Abstract
The utility model discloses a preheating mechanism used in a tail stove. The preheating mechanism used in the tail stove comprises a stove body, the inner portion of the stove body comprises a combustion chamber arranged on the lower portion and a steam generating section arranged on the upper portion, a water preheating section and an air preheating section are sequentially and additionally arranged above the steam generating section, a cold water inlet and a hot water inlet are formed in the water preheating section, and the hot water outlet is externally connected to the steam generating section through a water connecting pipe; a cold air inlet and a hot air outlet are formed in the air preheating section and the hot air outlet is externally connected to the combustion chamber through an air connecting pipe. The preheating mechanism used in the tail stove is simple in structure, reasonable in design and capable of preheating cold water in a water preheating chamber so that warm water can be obtained, cold air is preheated through an air preheating chamber so that hot air can be obtained, the use rate of tail gas is effectively increased, and the use requirements of an enterprise are satisfied.
Description
Technical field:
The utility model relates generally to technical field prepared by formaldehyde, relates in particular to a kind of preheating mechanism for the tail stove.
Background technology:
The final step of the production line of formaldehyde is the tail gas recycling will produced, and by the tail stove, the Btu utilization of tail gas is got up, and plays the effect of saving the energy.But the tail stove in the course of work is, is cold water first to be become to hot water finally be evaporated to hot gas, the air of simultaneously tail stove burning is cold air, invisible in the middle of, expended the energy of tail gas.
The utility model content:
The utility model purpose is exactly in order to make up the defect of prior art, and a kind of preheating mechanism for the tail stove is provided, and it has good pre-heat effect, makes the waste gas utilization rate reach maximization.
The utility model is achieved through the following technical solutions:
A kind of preheating mechanism for the tail stove, include body of heater, include the burner hearth of bottom and the producing steam section on top in body of heater, it is characterized in that: described producing steam section top has additional water preheat section and air preheat section successively, described water preheat section is provided with into cold water outlet and hot-water outlet, and described hot-water outlet is outer to be accessed in the producing steam section by water service pipe; Described air preheat section is provided with cool air inlet and hot air outlet, and hot air outlet is outer to be accessed in burner hearth by breather pipe.
A kind of preheating mechanism for the tail stove is characterized in that: in described producing steam section, be provided with some vertical tubes.
The utility model has the advantages that:
The utility model is simple in structure, reasonable in design, by being warm water by the first preheating of water preheat chamber cold water, by the gas preheating chamber, by the cold air preheating, is hot-air, has effectively increased the utilization rate of tail gas, has met the user demand of enterprise.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Referring to accompanying drawing.
A kind of preheating mechanism for the tail stove, include body of heater, include the burner hearth 3 of bottom and the producing steam section 2 on top in body of heater, producing steam section 2 tops have additional water preheat section 5 and air preheat section 4 successively, described water preheat section 5 is provided with into cold water outlet 6 and hot-water outlet 7, and described hot-water outlet 7 is outer by water service pipe 8 access producing steam sections 2; Described air preheat section 4 is provided with cool air inlet 9 and hot air outlet 10, and hot air outlet 10 is outer by breather pipe 11 access burner hearths 3.
Be provided with some vertical tubes 1 in producing steam section 2.
