Abstract

The utility model discloses a marsh gas heating stove; a fire grate type burner is arranged at the middle part and the lower part of a stove body, a marsh gas inlet pipe is downwards connected at thelower part of the burner, a control valve is outwards arranged in the middle of the gas inlet pipe in the stove body, a marsh gas ignition device is arranged on the burner, a controller and an electronic ignition circuit are arranged on the inner wall of the lower part of the stove body, a combustion chamber is arranged above the burner, a group of heat exchangers are arranged at the upper part inthe combustion chamber, a water inlet pipe and a water outlet pipe are outwards led out from the inside of the heat exchangers, a water pump is arranged on the water inlet pipe arranged at the bottompart of the stove body, a temperature sensor is arranged on the water outlet pipe arranged in the stove body, a waste gas exhaust chamber with the arc-shaped top part is arranged on the upper surfaceof an outlet of the combustion chamber above the heat exchangers, and an exhaust port is arranged at the top part of the waste gas exhaust chamber to the upper end of the stove body. The marsh gas heating stove uses a set of marsh gas ignition device to be matched with the marsh gas heating stove, thereby being capable of fully utilizing natural resources in the breeding industry, reducing breeding cost and realizing reliable installation and no pollution.

Description

The biogas heating stove

Technical field:

The utility model relates to heat supply, particularly a kind of biogas heating stove that is applicable to that the biogas that utilizes refuse landfill, sewage-farm and breed place construction of marsh gas tank to produce carries out heat supply.

Background technology:

At present, most of refuse landfill, sewage disposal and plant are all carrying out the biogas construction, utilize biogas to cook, heat up water and small power generation, but being used for the heating stove of heat supply all is to use coal or coal gas, not only the biogas of self producing can not be fully used, and brings inconvenience to the user.

Summary of the invention:

The purpose of this utility model provides a kind of biogas that not only produces nearby can access utilization, and makes things convenient for the user to save the biogas heating stove of equipment investment.

The technical solution of the utility model is finished as follows, it includes a body of heater, it is characterized in that: a fire grate type burner is installed in the middle and lower part of body of heater, the bottom of burner is connected with the biogas air inlet pipe downwards, a control valve outwards is installed in body of heater in the middle of the air inlet pipe, a biogas igniter is installed on burner, this igniter is to be installed in above the burner by igniting pin and sensing needle, there is lead one end to be connected electronic igniting circuit on the igniting pin, the electronic igniting circuit via controller is connected with power pack, controller and electronic igniting circuit are installed on the body of heater lower inner wall, above burner, be provided with the combustion chamber, the top is equipped with one group of heat exchanger in the combustion chamber, outwards lead to water inlet pipe and outlet pipe in the heat exchanger, bottom in body of heater on the water inlet pipe is provided with water pump, in body of heater, be provided with temperature sensor on the outlet pipe, be provided with a toxic emission chamber that the top is curved above the heat exchanger above combustor exit, top, toxic emission chamber is connected with exhaust outlet to the body of heater upper end.The utility model cooperates with the biogas heating stove with a cover biogas igniter, can make full use of the natural resources in aquaculture, reduces aquaculture cost, installs reliable, pollution-free.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the electrical schematic diagram of biogas igniter of the present utility model.

The specific embodiment:

Further describe embodiment in conjunction with above accompanying drawing, a fire grate type burner 2 is installed in the middle and lower part of a body of heater 15, the burner bottom is connected with biogas air inlet pipe 11 downwards, a control valve 9 outwards is installed in body of heater in the middle of air inlet pipe, a biogas igniter is installed on burner, this igniter is by igniting pin 3, sensing needle 3-1, electronic igniting circuit 13, controller 12 and power pack 16 thereof, earth connection 17 is formed, igniting pin one end has lead to connect electronic igniting circuit, the other end connects ground wire, the sensing needle lower end is connected in parallel on the electronic igniting circuit with the igniting pin, electronic igniting circuit again be installed in body of heater on central controller 12 be communicated with, controller connects power pack 16, above burner, be provided with a combustion chamber 4, the top is equipped with one group of heat exchanger 5 in the combustion chamber, outwards lead to water inlet pipe 14 and outlet pipe 10 in the heat exchanger, in body of heater inner bottom part one side water pump 1 is installed on the water inlet pipe, a temperature sensor 8 is installed outside the body of heater inner combustion chamber on the outlet pipe, be provided with a toxic emission chamber 7 that the top is curved above the top of combustion chamber heat exchanger, top, toxic emission chamber is communicated with exhaust outlet 6 to the body of heater upper end.This biogas heating stove can be widely used in the office dormitory, culture dormitory and all need install the occasion of heating.Its electric control principle is; provide the galvanic current source to central controller and electronic igniting circuit thereof by power pack; central controller the signal that provided by temperature sensor is provided and provides control signal from the magnetic valve and the water circulating pump of trend igniter; the igniting pin is got angry and is lighted biogas; the fire grate type burner operation; autostop when water temperature reaches 85 ℃ forms 24 hours automatic loop control indoor temperatures.
