Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of garbage treatment, in particular to an automatic waste gas purification treatment system for a garbage transfer station. Background Art
[0002] Since urban domestic garbage contains more organic matter such as leftovers, vegetable leaves, skins, hair, fat, scraps of poultry, animals and fish, etc. and a certain amount of water, a certain amount of ammonia, hydrogen sulfide, organic amines, methane and other odorous gases will be produced during the accumulation process due to poor ventilation and the action of microorganisms, which are generally referred to as garbage odor. Because a large amount of residential domestic garbage is generated in residential areas, the collection and treatment of garbage is also built nearby in the surrounding areas of densely populated areas. In this way, the odor generated by the centralized stacking site of the garbage treatment process will inevitably pollute the surrounding environment. Especially in the hot summer, the odor of the garbage treatment station makes the station staff miserable. Some garbage compression stations also have the problem of garbage leachate infiltrating into the ground near the treatment station, or spreading to a larger area from high to low according to the terrain, causing a larger range of impact.
[0003] The automatic waste gas purification treatment system of the garbage transfer station is a system specially designed to treat the waste gas generated by the garbage transfer station. The system collects, purifies and treats the waste gas in an automated way to ensure that the waste gas emissions meet environmental protection standards and reduce pollution to the environment. However, the existing treatment system is not ideal for some high-concentration malodorous gases, such as ammonia, hydrogen sulfide, methyl mercaptan, etc. The removal efficiency is unstable. The system generally only treats the waste gas by pumping, without subsequent purification measures. Harmful substances in the waste gas, such as ammonia, hydrogen sulfide, methyl mercaptan, etc., cannot be effectively removed, and the operating cost is high and requires a lot of energy consumption.

[0027] By means of the waste gas detection devices 1 arranged at multiple points in the transfer station, the waste gas in the transfer station is monitored and collected, and the collected data is sent to the data processing server 2 for analysis and processing. The data processing server 2 automatically adjusts the high-speed, medium-speed and low-speed operating states of the negative pressure exhaust device 3, the space spray device 4 and the ion air supply device 5 based on the air quality in the transfer station. When the odor concentration is much higher than the set value, the high-speed mode is adopted, when the odor concentration is less than the set value, the medium-speed mode is adopted, and when the odor concentration is lower than the set value, the low-speed mode is adopted; under energy-saving conditions, the air quality in the transfer station is improved to the maximum extent. The data processing server 2 can archive and store the air quality data and generate electronic spreadsheets to facilitate users to query historical data.
