Abstract

The invention discloses a Venturi scrubber with a changeable structure. The Venturi scrubber comprises a Venturi tube main body, a convergent section module, a throat module, a divergent section module, a medium bolt group, a long bolt group, a short bolt group, a transverse sprayer group, medium bolts, long bolts, short bolts, a transverse sprayer, a downstream sprayer, an inlet flange, an outletflange, a bolt hole group, bolt holes, a convergent cavity, a downstream sprayer through hole, convergent section bolt holes, a throat cavity, transverse sprayer through holes, throat bolt holes, a divergent cavity and divergent section bolt holes. The convergent section module, the throat module, the divergent section module, the transverse sprayer and the downstream sprayer are placed in the Venturi tube main body by changing a collocating combination mode of the convergent section module, the throat module, the divergent section module, the transverse sprayer and the downstream sprayer, and the Venturi scrubber with different cross section types and spray modes is formed after fixation by the bolts. The Venturi scrubber can meet the requirement for different decoking effects and savesinput time and cost, and the service life of the Venturi scrubber is prolonged.

Description

technical field [0001] The invention relates to the technical field of Venturi scrubbers, in particular to a Venturi scrubber whose structure can be changed. Background technique [0002] Biomass gasification produces tar while producing biomass gas. As the temperature of the biomass gas decreases, the gaseous tar will turn into tar droplets, and the condensed tar particles are difficult to remove. After the gas enters the downstream equipment, it will cause wear and corrosion of the gas transmission pipeline and gas equipment, reducing the its use value. Therefore, it is very important to purify and decoke biomass gas, and it is a conventional method to use a Venturi scrubber for gas decoking. [0003] Venturi scrubbers can be divided into circular and rectangular according to the type of cross-section, and can be divided into forward spray and horizontal spray according to the spraying method of washing liquid. In the actual work process, there are often requirements fo...
