A sealed biogas stove based on airflow

Abstract

The invention relates to the technical field of stoves, and discloses a novel biogas stove with good sealing performance based on airflows. The novel biogas stove comprises a stove body, wherein a fixing frame is fixedly arranged on the upper surface of the stove body, an air inlet pipe is fixedly installed on the lower surface of the stove body, an air baffle is arranged in the air inlet pipe, afixing rod is fixedly installed on the upper surface of the air baffle, a connecting rod is fixedly arranged at the upper end of the fixing rod, a fixing ball is fixedly installed at the middle of theconnecting rod in an inserting mode, a fixing ring is fixedly installed inside the fixing frame, fixing blocks are fixedly installed at the lower end of the fixing ring, and an air nozzle is fixedlyarranged at protruding parts of the fixing blocks. According to the novel biogas stove, trough the cooperation of a moisture absorption plate and an oxygen removal block, drying of the environment inthe stove body can be kept, the metal of the air inlet pipe is prevented from being wet oxidation by wetting, meanwhile, the deoxygenization block is adopted, a relatively oxygen-free environment in the stove body is guaranteed, so that the upper end of the air inlet pipe is not prone to generate tempering under the condition that no oxygen or oxygen is insufficient.

Description

technical field [0001] The invention relates to the technical field of stoves, in particular to a biogas stove sealed based on air flow. Background technique [0002] Biogas stove is one of the new energy appliances, and it has been widely used. Biogas stove is an atmospheric stove. It consists of four parts: nozzle, air regulating plate, ejector and head. ), and the key components that convert the pressure energy of biogas into kinetic energy are generally made of metal materials (preferably copper). [0003] At present, in the existing biogas stoves, air is sucked in from the intake pipe by negative pressure and mixed with gas. The combustion head has a section of horizontal tailpipe and an upward head, and the head is covered with vertical gas outlet holes. The disadvantage of this structure is , when the gas stove is about to be turned off and used, the burning flame is easy to enter the intake pipe along the gas, and it is easy to produce a flashback at the head of the...

Problems solved by technology

[0003] At present, in the existing biogas stoves, air is sucked in from the intake pipe by negative pressure and mixed with gas. The combustion head has a section of horizontal tailpipe and an upward head, and the head is covered with vertical gas outlet holes. The disadvantage of this structure is , when the gas stove is about to be turned off and used, the burning flame is easy to enter the intake pipe along the gas, and it is easy to produce a flashback at the head of the intake pipe, which may cause the intake pipe to burn, which is harmful to people's normal use. Brings a larger security risk, not easy to protect people's safety

[0004] In order to solve the above problems, the inventor proposed a biogas stove that is sealed based on airflow, which has the advantage that after use, the gas outlet at the upper end of the intake pipe can completely isolate the outflow of biogas, preventing the burning flame from entering the inlet along with the gas. trachea, resulting in flashback at the head of the intake pipe
