Disclosed is an internal circulation type lampblack purifier. The internal circulation type lampblack purifier comprises a shell, an air inlet, an air outlet, an air inlet channel, an air outlet channel, a fan device, a mechanical grease separator, a gas purification device and a cooling device, wherein the air inlet and the air outlet are arranged on the shell; the mechanical grease separator is arranged at the air inlet or in the air inlet channel; and the cooling device is arranged at the air outlet and comprises a water supply pipe, water spray guide plates, a water mist baffle plate, a spray pipe and a water receiving tank, the spray pipe communicates with the water supply pipe, spray nozzles are arranged on the spray pipe and face the water spray guide plates, the water receiving tank is located below the water spray guide plates, and the water mist baffle plate is provided with blades at certain gaps. According to the internal circulation type lampblack purifier, the cooling device is arranged, so that the temperature of discharged gas is effectively reduced, high-temperature water vapor in the discharged gas is eliminated, and the influence of the high-temperature water vapor on the indoor environment is prevented.

The present disclosure relates to testing, analysis and treatment of an environment, wherein one or more baseline(s) is established for the environment. Systems and methods for detecting, treating, comparing and testing for mold, mold spores and mold fragments physically present or in the air of an environment are disclosed herein, as well as methods for remediating the effects of mold in the environment.

In a method for controlling unpleasant odors in discharge air from containers, rooms or plants in which strong smelling substances such as feces, waste or highly odorous foods are stored or processed, a fluid is introduced into the discharge air in a finely distributed form, which physically and/or chemically neutralizes the odor of the substances contained in the discharge air. The fluid is a 0.1% to 8% aqueous solution of an active substance concentrate which is 55-65 wt.-% triethylcitrate, 17.5 to 22.5 wt.-% 1,2 propanediol and 17.5 to 22 wt.- % di-propylene glycol-methylether. Alternatively, the fluid can also be a mixture of a suitable propellant gas mixture and the active substance concentrate specified above.
