Complex malodor removing equipment

A complex malodor removing equipment comprising:

• a neutralizing module which dissolves a portion of malodor-causing substances, in malodorous gas introduced from malodor-producing equipment, in liquid water and removes same, and which removes the portion of the malodor-causing substances by introducing an acidic substance or an alkaline substance into the malodorous gas from outside, using a neutralizing reaction;
• and
• a balancing module which is placed at downstream of the neutralizing module with respect to a flow direction of the malodorous gas and removes a portion of the malodor-causing substances by introducing a reducing agent or an oxidizing agent into the malodorous gas from outside, using a reduction reaction or an oxidation reaction,
• wherein the neutralizing module comprises:
• an alkaline neutralizing module which introduces an acidic substance from outside and removes an alkaline malodor-causing substance from the malodor-causing substances introduced from the malodor-producing equipment in order to neutralize same;
• and
• an acidity neutralizing module which is placed at downstream of the alkaline neutralizing module, introduces an alkaline substance from outside and removes an acidic malodor-causing substance discharged while not being removed by the alkaline neutralizing module, from the malodor-causing substances in order to neutralize same, and
• the complex malodor removing equipment further comprising a suction fan, which is provided on a gas line in which the malodorous gas passes through the balancing module and is discharged and which allows the inside of the alkaline neutralizing module, the acidity neutralizing module and the balancing module in a negative pressure state.
