Description

Technical Field

[0001] This utility model relates to the field of waste incineration technology, specifically to a micro-powered water washing integrated device for waste incineration fly ash. Background Technology

[0002] Fly ash from waste incineration is a hazardous waste generated during the incineration process. It contains harmful substances such as chloride salts and heavy metals. Direct disposal can easily cause soil and water pollution. It needs to be treated to achieve safe landfill or resource utilization. It is a key treatment object in the waste incineration disposal chain.

[0003] Current fly ash washing technologies mostly rely on equipment such as multi-stage mixing tanks, which have problems such as high energy consumption, large footprint, and frequent equipment failures. In response, we propose a micro-powered integrated fly ash washing device for waste incineration. Utility Model Content

[0004] The purpose of this invention is to provide an integrated micro-powered water washing device for waste incineration fly ash to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a micro-powered water washing integrated device for waste incineration fly ash, comprising a tank, a hopper fixedly connected to the top of the tank, a discharge pipe embedded in the middle of the bottom of the tank, a dust-raising pipe embedded through the hopper and the top of the tank, an inner conical fixed plate fixedly connected to the bottom of the dust-raising pipe, a liquid guide pipe wound around the outer wall of the dust-raising pipe, one end of the liquid guide pipe extending to the outer end of the tank, a water pump fixedly connected to the upper end of the outer wall of the tank, the bottom end of the liquid guide pipe coiled and embedded in the conical surface of the inner conical fixed plate, a plurality of nozzles embedded on the liquid guide pipe located on the inner conical surface, a plurality of chambers opened in the inner wall of the dust-raising pipe, and a plurality of elastic balls arranged inside the chambers.

[0006] Preferably, the bottom of each tank is fixedly connected with several support legs.

[0007] Preferably, the output end of the water pump is connected to one end of the liquid guide pipe, and the output end of the water pump is fixedly connected to a connecting pipe.

[0008] Preferably, the cross-sections of several nozzles are all arranged in an inward tilt.

[0009] Preferably, the plurality of elastic balls are made of either silicone or fluororubber.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the hot water is delivered by a water pump and an inward-curving nozzle forms an air curtain, eliminating the need for traditional stirring equipment. The micro-power water washing is achieved through water flow and heat effect, which greatly reduces energy consumption. Second, the hot water improves the dissolution efficiency of chloride salts and heavy metals, and the air curtain enhances the contact between fly ash and water, thus improving the pretreatment effect. Third, the elastic ball in the chamber bounces when heated, effectively reducing fly ash adhesion to the pipes and reducing the risk of blockage. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figures 1-4 As shown, this utility model provides the following technical solution: Example 1: A micro-powered water washing integrated device for waste incineration fly ash includes a tank 1, a hopper 11 fixedly connected to the top of the tank 1, a discharge pipe 12 embedded in the middle of the bottom of the tank 1, and several support legs 13 fixedly connected to the bottom of the tank 1.

[0015] When in use, the fly ash from the incineration of the waste to be treated is first mixed with an appropriate amount of water to make fly ash slurry. The fly ash slurry is then fed into the tank 1 at a uniform speed through the hopper 11 at the top of the tank 1. The treated fly ash mud is discharged from the discharge pipe 12 at the bottom center of the tank 1. The support legs 13 stably support the tank 1 to ensure that the entire micro-power water washing process proceeds smoothly.

[0016] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a dust-raising pipe 2 is embedded through the top of the hopper 11 and the tank body 1; an inner conical fixed plate 21 is fixedly connected to the bottom of the dust-raising pipe 2; a liquid guide pipe 22 is wound around the outer wall of the dust-raising pipe 2, and one end of the liquid guide pipe 22 extends to the outer end of the tank body 1; a water pump 220 is fixedly connected to the upper end of the outer wall of the tank body 1; the bottom end of the liquid guide pipe 22 is coiled and embedded in the inner conical surface of the inner conical fixed plate 21; several nozzles 222 are embedded on the liquid guide pipe 22 located on the inner conical surface; several chambers 201 are opened in the pipe wall of the dust-raising pipe 2; several elastic balls 23 are arranged inside the chambers 201; the output end of the water pump 220 is connected to one end of the liquid guide pipe 22, and a connecting pipe 221 is fixedly connected to the output end of the water pump 220; the cut surfaces of the several nozzles 222 are all inwardly inclined; and the several elastic balls 23 are made of either silicone or fluororubber.

[0017] In operation, the fly ash from the waste incineration plant is fed uniformly into the hopper 11. The ash is carried by the airflow into the dust collection pipe 2 and falls slowly and naturally. The water pump 220 is started, and hot water is supplied to the liquid guide pipe 22 via the connecting pipe 221. The hot water flows along the liquid guide pipe 22 and is sprayed out inwards through the inwardly angled nozzles 222 on the conical surface of the inner conical fixed plate 21 at the bottom of the dust collection pipe 2, forming an annular air curtain that "intercepts and encapsulates" the falling fly ash, improving the mixing efficiency between fly ash and liquid. Furthermore, the hot water itself enhances the dissolution efficiency of the fly ash, strengthening the pre-washing effect. Simultaneously, the heat from the hot water in the liquid guide pipe 22 is transferred to the wall of the dust collection pipe 2, causing the air in the chamber 201 to expand and push the elastic ball 23 to bounce within the chamber 201, effectively reducing fly ash adhesion to the pipe wall. The pre-washed material falls into the lower part of the tank 1, and the finally treated fly ash sludge is discharged from the discharge pipe 12.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
