Description

TECHNICAL FIELD

[0001] The utility model relates to garbage treatment technical field, concretely is a garbage incineration power plant garbage pool stinkproof system. BACKGROUND

[0002] The existing garbage incineration power plant adopts the buried unloading door in the design of garbage pool unloading door. In order to guarantee that the stench produced by garbage does not overflow, thereby avoiding causing serious pollution to the surrounding environment, the unloading door is mostly made of steel plate. The door body is extremely thick, and its weight can reach about 1.5 tons. The thick door body can effectively block the stench of garbage from overflowing in the closed state, which provides a certain guarantee for the normal operation of the garbage incineration power plant. With the continuous development and promotion of urban construction, some large-scale large garbage incineration power plants emerge as the times require. Due to the increasing demand for garbage disposal, the garbage pools of these large garbage incineration power plants are relatively large. Generally, 10 or more unloading doors are set. In order to prevent traffic jams of garbage trucks, multiple unloading doors need to be opened simultaneously for feeding when the garbage truck feeds and the feeding is concentrated. However, the unloading doors cannot be opened and closed at any time during the feeding stage. In this case, the garbage pool cannot maintain a basic negative pressure state. At this time, the stench produced by the garbage will overflow, which will have a very serious impact on the air quality around the garbage pool, not only causing trouble to the surrounding residents, but also damaging the ecological environment.

[0003] In order to prevent the stench from overflowing, some garbage power plants use a special roller shutter. This roller shutter generally needs to add deodorizing materials such as bamboo charcoal or activated carbon. These deodorizing materials can adsorb stench within a certain period of time. However, due to the limited service life of the deodorizing materials, the adsorption materials will gradually lose activity after a period of use. Therefore, the roller shutter needs to be replaced and maintained regularly, which undoubtedly increases the operating cost of the garbage power plant and is not conducive to the efficient and stable operation of production and operation.

[0030] The working principle of the garbage pool odor prevention system of the garbage incineration power plant is as follows:

[0031] When the garbage truck 1 moves to the unloading area, the weight sensor 2 converts the current entire weight data into a 4-20MA signal and transmits it to the control system, wherein the unloading area is the area where the weight sensor 2 is arranged in front of the inclined channel 15 of the garbage pool 7. After calculation, if the weight meets the preset weight, the control system controls the odor prevention roller shutter 5 to start working, the winding motor of the roller shutter main body winds the roller shutter main body, and the roller shutter main body is automatically lifted to a height of 1 meter from the ground. At the same time, the control system controls the pre-process to supply water to the flushing water pipe 11, and the high-pressure nozzles 12 wash the roller shutter by spraying water. After 10 seconds or a set time, the high-pressure nozzles 12 stop spraying water. If a large amount of smoke is generated during the unloading process, the smoke sensing alarm device 8 will automatically alarm, reminding the on-site operator to carry out subsequent fire extinguishing. After the unloading is completed, the garbage truck 1 leaves the unloading area, and when the weight in the gravity sensing area is less than 1T, the control system will control the odor prevention roller shutter 5 to automatically drop to the lowest position of the guide rail and maintain the negative pressure of the garbage pool 7.
