Water tank spray range hood

Abstract

The invention discloses a water tank spray type range hood which comprises a soot removal tank, a high-pressure water pump and a cleaning water collecting tank. A water spray assembly is further arranged in the soot removal tank and is connected with the high-pressure water pump; the cleaning water collecting tank communicates with the bottom part of the soot removal tank; a first array type filter screen group, a funnel type ventilation cavity and a variable funnel type filter are sequentially arranged in the soot removal tank; an inlet edge of the funnel type ventilation cavity is fixedly connected with the inner wall of the soot removal tank in a sealing way; and an inlet of the variable funnel type filter is bound on an outlet at the tail part of the funnel type ventilation cavity. According to the water tank spray type range hood provided by the invention, the funnel type ventilation cavity is arranged in the soot removal tank, and the variable funnel type filter is arranged at the tail part of the funnel type ventilation cavity, so that the problem that soot is easy to run out due to non-tight connection between the first array type filter screen group and the soot removal tank is solved; and water is ingeniously mixed with a targeted drug so as to chemically-physically remove waste gas soot, so that the purification degree of gas passing through an air outlet is better.

Description

technical field [0001] The invention belongs to the technical field of range hoods, and in particular relates to a water tank spray type range hood. Background technique [0002] With the development of the economy, there are more and more factories in the manufacturing industry, garbage incinerators, heating boilers in winter, and people set up restaurants for delicious food, resulting in increasing emissions of dust, oil fume, and exhaust gas, and various air pollution is becoming more and more serious. , threaten people's life and health, and more seriously destroy the only earth environment in which people live. The prospect is very dire. At present, there are many oil fume removal appliances, but the effect is not ideal. Some directly discharge the exhaust gas into the sky, and some force it into the sewer , leading to more widespread and serious pollution.

Problems solved by technology

[0002] With the development of the economy, there are more and more factories in the manufacturing industry, garbage incinerators, heating boilers in winter, and people set up restaurants for delicious food, resulting in increasing emissions of dust, oil fume, and exhaust gas, and various air pollution is becoming more and more serious. , threaten people's life and health, and more seriously destroy the only earth environment in which people live. The prospect is very dire. At present, there are many oil fume removal appliances, but the effect is not ideal. Some directly discharge the exhaust gas into the sky, and some force it into the sewer , leading to more widespread and serious pollution. Some oil fume removal methods are to carry out water cleaning above the stove. If this method is added with medicinal chemical oil fume exhaust gas, it is very dangerous for the problem of drug contamination of food. The effect is very bad, only about 40%. Another method that is highly praised by people is the electrostatic removal of oil fume and exhaust gas. This method has a first-class effect in a very short period of time. In the laboratory, it failed very quickly because the voltage it used was very high, above 15,000 volts, it was very easy to short circuit, easy to arc and ignite, the fire risk was very high, and it was easy to hurt people with high voltage. If it exists for a long time, the oil fume and dust adhere to the machine cavity and pipes, and it is difficult to clean up. It is a high-frequency switching power supply to obtain high voltage, and its power is quite large, which seriously threatens the health of kitchen workers.
