Technical Field

The invention relates to the technical field of low-grade fuel burning technology and process air conditioning, in particular to a system and a method for treating VOCs and controlling temperature in a coating workshop in a combined manner.

Background

VOCs are abbreviations for Volatile Organic Compounds (Volatile Organic Compounds). The pretreatment/coating workshop generates gases containing VOCs, the VOCs gases cannot be directly discharged without being treated, and when the concentration of the VOCs in the workshop is too high, the gases can cause adverse effects on the physical condition of operators. Therefore, the waste gas containing VOCs from the pretreatment/coating workshop should be treated by a suitable treatment device. A concentration of VOCs may be used as fuel to provide heat. The VOCs are treated by a biological method, an adsorption method, a membrane separation method, a catalytic combustion method, a heat accumulation oxidation method and the like in a more common way; in order to better treat the adsorbed VOCs, an adsorption method is often combined with a catalytic combustion method or a regenerative oxidation method, but the heat generated by the combustion of the VOCs is not effectively utilized, so that the energy is wasted. There are many methods and devices for treating VOCs, but there are few devices for treating VOCs that reuse VOCs as energy.

The temperature and humidity of the pretreatment/coating workshop can affect the coating effect, the high temperature and humidity can cause cracks on the coating surface, the low temperature can prolong the drying time and reduce the operation efficiency, and therefore, the temperature and humidity of the pretreatment/coating workshop need to be ensured to be maintained within the process requirement range, and the pretreatment/coating workshop should be provided with a workshop air conditioner to adjust the workshop temperature.

The absorbent lithium bromide/ammonia with strong water absorbability provides a low-pressure environment for water, so that the water can be evaporated and refrigerated in a low-temperature environment, and further the 5-7 ℃ chilled water is prepared. During refrigeration, the low concentration absorbent lithium bromide/ammonia releases refrigerant water vapor and condenses it into water which is then evaporated at low pressure to produce the refrigeration effect, after which the refrigerant vapor generated during evaporation is absorbed by the high concentration absorbent lithium bromide/ammonia solution to maintain the desired low pressure. The absorption type refrigerating and heating air-conditioning system needs fuel to burn to provide heat, and energy waste can be caused by adopting single fuel.
