Problems solved by technology

Due to the fact that the selected information is not necessarily complete, and there are bound to be errors in the selection of manual charts, the model of the selected blower is not necessarily accurate and reasonable, and the best energy-saving effect cannot be achieved. This is also the reason for the high energy consumption of the blower. one

Embodiment Construction

[0013] Generally, technicians who know a certain method of establishing a computer database can establish a database after mastering the blower model samples commonly used in various blower sewage treatment processes. The database includes the main technical performance parameters of the blower, such as flow, pressure, shaft power, caliber, Speed, motor power, etc. In order to meet the needs of users for the selection of new blowers, the database has functions such as adding, modifying, deleting, and querying, which is convenient for users to maintain and update the database in time.

[0014] see figure 1 The operation flow chart of the implementation of the intelligent selection method of the blower, and the implementation methods of the optimal selection of the blower include:

[0015] Step 1. Run the program, and the user inputs the original design data and design parameters;

[0016] Step 2. Calculate the air supply volume and required pressure of the activated sludge sy...

Abstract

The invention relates to an optimization type selection method, a sample database and a system of fans in sewage treatment plant design. The method includes step1 calculating air supply quantity and required pressure in the largest flow time section, the average flow time section and the smaller flow time section of an activated sludge system, step2 selecting type selection accuracy of the fans and maximum number of working platforms; step3 preferably selecting fan types meeting design requirements of the three flow time sections and the number and the running state of the working platforms in each time section; step4 returning to execute the step2 and reducing the type selection accuracy of the fans or determining the maximum number of the working platforms again if fans meeting the type accuracy requirement cannot be selected; and step5 queuing the fans according to energy consumption if the types of the selected fans are larger than 1 and providing the most energy-saving fan and a running combination of the fan for a user to achieve the aims of saving energy and improving working efficiency.

Description

technical field [0001] The invention relates to a method for optimal selection of a blower in the design of a sewage treatment plant, specifically [0002] Said is a blower selection method and sample database. Background technique [0003] In the field of sewage treatment technology today, the activated sludge method is one of the most widely used technologies. Most of the sewage treatment plants using the activated sludge process at home and abroad use the blast aeration process. The energy consumption of the blower accounts for more than half of the total energy consumption of the whole sewage plant, which is the main reason for the high energy consumption of the activated sludge process. At present, when selecting the type of blower, the designer manually selects the type by consulting the design manual and the sample of the blower. Due to the fact that the selected information is not necessarily complete, and there are bound to be errors in the selection of manual ch...
