Abstract
The utility model provides an oily sludge deep dehydration system, the blending pond is connected to the head tank, and charge device is connected in the blending pond, and the blending pond passes through mud elevator pump and connects plate and frame filter press, and plate and frame filter press connects the dehydration sludge pond, and the dehydration sludge pond passes through the auger delivery ware and connects the thick liquid piece desiccator, and the conduction oil circulating pump is connected to the thick liquid piece desiccator, and the product jar is connected to thick liquid piece desiccator output. The utility model discloses an oily sludge degree of depth dewatering system combines together traditional mechanical dehydration and hollow paddle drying equipment, after oily sludge is through mechanical dehydration, sends into hollow paddle desiccator, and the logical conduct oil as heat transfer medium in the hollow paddle, and oily sludge and paddle fully contact carry out the heat exchange. The paddle can not only play a role in heat transfer, but also can uniformly stir the oily sludge so as to uniformly and fully dry the sludge. The device has the advantages of high dehydration rate, uniform dehydration, simple operation, high treatment efficiency and the like.
Description
Technical Field
The utility model relates to an environmental engineering solid waste handles field.
Background
The oily sludge is mainly generated in the processes of crude oil extraction, gathering and refining, such as flocs formed by water purifying agents added to water bodies when treating oil extraction sewage; corrosion products and scales generated in oil transportation equipment and oil pipelines; tank bottom sludge deposited at the bottom of an oil product storage tank and the like, and the oily sludge generally has the characteristics of high viscosity, fine particles, difficult dehydration and the like.
The traditional oily sludge dewatering treatment usually adopts mechanical dewatering, the method is single, and the problems of low dewatering rate, incapability of deep dewatering and the like exist.
SUMMERY OF THE UTILITY MODEL
In order to make the oily sludge reach higher dehydration effect and carry out resource utilization to it with better, the utility model provides an oily sludge deep dehydration system.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the utility model provides an oiliness mud deep dehydration system, the blending pond is connected to the head tank, and charge device is connected in the blending pond, and the blending pond passes through mud elevator pump and connects plate and frame filter press, and plate and frame filter press connects the dehydration sludge pond, and the dehydration sludge pond passes through the auger delivery ware and connects the thick liquid piece desiccator, and the conduction oil circulating pump is connected to the thick liquid piece desiccator.
The output end of the pulp sheet drying machine is connected with the product tank.
The utility model discloses an oily sludge degree of depth dewatering system combines together traditional mechanical dehydration and hollow paddle drying equipment, after oily sludge is through mechanical dehydration, sends into hollow paddle desiccator, and the logical conduct oil as heat transfer medium in the hollow paddle, and oily sludge and paddle fully contact carry out the heat exchange. The paddle can not only play a role in heat transfer, but also can uniformly stir the oily sludge so as to uniformly and fully dry the sludge. The device has the advantages of high dehydration rate, uniform dehydration, simple operation, high treatment efficiency and the like.
Drawings
FIG. 1 is a schematic diagram of the deep dehydration system for oily sludge of the utility model.
Detailed Description
The utility model discloses an oily sludge deep dehydration system principle is as shown in FIG. 1, and the mixing tank is connected to the head tank, and charge device is connected to the mixing tank, and the mixing tank passes through mud elevator pump and connects plate and frame filter press, and plate and frame filter press connects the dehydration sludge pond, and the dehydration sludge pond passes through the auger delivery ware and connects the thick liquid piece desiccator, and the conduction oil circulating pump is connected to the thick liquid piece desiccator, and the product jar is connected to thick liquid piece desiccator output.
The working principle is as follows: (1) storing the oily sludge in a raw material tank, fully mixing the oily sludge with the added medicament in a mixing pool, and pumping the mixture into a plate-and-frame filter press by a sludge lifting pump for preliminary dehydration;
(2) the sludge cake formed after the oily sludge is dehydrated by a plate-and-frame filter press is sent into a dehydration sludge pool, and then is crushed by a screw conveyor and is conveyed into a paddle dryer for deep dehydration;
(3) the heat conducting oil transfer pump transfers high-temperature heat conducting oil to the hollow blade, the mud cake is broken into small pieces along with the violent stirring of the hollow blade, the small pieces are fully contacted with the blade, water is evaporated and removed, and a dry product is obtained and is sent into a product tank.
The system combines the traditional mechanical dehydration equipment with the hollow blade drying equipment, oily sludge is mechanically dehydrated and then is sent into the hollow blade drying machine, heat conduction oil is introduced into the hollow blades to serve as a heat transfer medium, and the oily sludge is fully contacted with the blades for heat exchange. The paddle can not only play a role in heat transfer, but also can uniformly stir the oily sludge so as to uniformly and fully dry the sludge.
Claims (2)
1. The deep dehydration system for the oily sludge is characterized in that: the blending pond is connected to the head tank, and charge device is connected in the blending pond, and the blending pond passes through the mud elevator pump and connects plate and frame filter press, and plate and frame filter press connects the dehydration sludge impoundment, and the dehydration sludge impoundment passes through the auger delivery ware and connects the thick liquid piece desiccator, and the conduction oil circulating pump is connected to the thick liquid piece desiccator.
2. The deep dewatering system for oily sludge according to claim 1, wherein: the output end of the pulp sheet drying machine is connected with the product tank.
