Abstract
The invention discloses heat recovery equipment for a gas heating furnace. The equipment comprises a hearth, wherein the bottom of the hearth is provided with a nozzle and the top of the hearth is provided with a circulating fan; a nozzle waste gas recovery pipe is arranged on the nozzle; one end of a heat exchange fan is connected with the nozzle waste gas recovery pipe and the other end of the heat exchange fan is connected with a waste gas air inlet pipe arranged on the circulating fan; and the nozzle is a sealed nozzle and can fully combust gas. By the equipment, the waste heat of waste gas in the gas heating furnace can be fully utilized, the heating energy is saved, and the aims of saving energy and reducing emission are fulfilled.
Description
Technical field:
The present invention relates to a kind of gas-fired heater, specifically, the present invention relates to a kind of gas-fired heater heat recovery equipment.
Background technology:
Now, all be provided with gas-fired heater in many factories, but general gas-fired heater all is in line mode discharges gas, on the one hand atmosphere is caused more serious pollution, owing to burn, the gas waste-heat temperature can reach about 300 degree～400 degree, owing to be not fully utilized on the other hand, be easy to like this temperature of air is impacted, temperature is further risen; Because advocate low-carbon (LC) society, it is very important that energy-saving and emission-reduction become, so this straight-line gas-fired heater can not be complied with the requirement in epoch, uneconomical also not environmental protection.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of gas-fired heater heat recovery equipment that can make full use of the waste heat of gas.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions.
This gas-fired heater heat recovery equipment comprises burner hearth, described burner hearth bottom is provided with burner, and the top is provided with circulating fan, and burner is provided with the burner exhaust gas recycling tube, heat-exchange fan one end is connected with the burner exhaust gas recycling tube, and the other end is connected with waste gas blast pipe on being located at circulating fan.
For the combustion gas in the burner is fully burnt, described burner is closed burner.
Compared with prior art, advantage of the present invention is: after adopting this structure, the waste gas residual heat in the gas-fired heater can be fully used, and can save the energy of heating, reaches the purpose of energy-saving and emission-reduction.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of gas-fired heater heat recovery equipment;
1, burner 2, burner exhaust gas recycling tube 3, heat-exchange fan 4, circulating fan
5, waste gas blast pipe 6, burner hearth
The specific embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
Gas-fired heater heat recovery equipment structure shown in Figure 1 is provided with burner 1 in the bottom of burner hearth 6 among the figure, and described burner 1 is closed burner, and the combustion gas in the burner 1 can fully be burnt; Be provided with burner exhaust gas recycling tube 2 on burner 1, burner exhaust gas recycling tube 2 reclaims 1 waste gas after burning of burner; The other end of burner exhaust gas recycling tube 2 is connected with a port of heat-exchange fan 3, and an end of the waste gas blast pipe 5 on another port of heat-exchange fan 3 and the circulating fan 4 is connected; Circulating fan 4 and exhaust inlet pipe 5 communicate with burner hearth 6; The waste gas that exhaust gas recycling tube 2 is absorbed enters by heat-exchange fan 3 in the waste gas blast pipe 5 of circulating fan 4, and circulating in burner hearth 6 of waste gas under the effect of circulating fan 4, additional heat increases the heat utilization efficiency of combustion gas, reaches the purpose of energy-saving and emission-reduction.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
