The invention provides a combined heat and power generation system with regulating valves adapting to changes. According to the combined heat and power generation system with the regulating valves adapting to the changes, the first regulating valve is arranged on a hot water supply pipe to regulate hot water entering into a heat exchanger; the second regulating valve is arranged on a water inlet pipeline of a radiator, data connection is conducted between a programmable logic controller and the first regulating valve as well as between the programmable logic controller and the second regulating value, and when the opening degree of the second regulating valve changes, the opening degree of the first regulating valve changes correspondingly to enable the hot water input into the heat exchanger to change correspondingly. According to the combined heat and power generation system with the regulating valves adapting to the changes, the heat exchange efficiency is maximized through the corresponding changes of the regulating valves, the energy is saved, and the purposes of protecting environment and saving energy are achieved.

The invention provides an intelligent-control efficient kiln waste heat utilization system which comprises a kiln, a main flue, a bypass flue and a gas-water heat exchanger. Smoke generated by the kiln enters the gas-water heat exchanger through an inlet of the bypass flue, and the smoke after heat exchanging flows into the main flue through an outlet of the bypass flue to be discharged. A main flue adjustment valve is arranged at the position, between the inlet of the bypass flue and the outlet of the bypass flue, of the main flue and used for adjusting the amount of the smoke of the main flue; meanwhile, a bypass flue adjustment valve is arranged on the bypass flue and used for adjusting the amount of the smoke of the bypass flue. According to the intelligent-control efficient kiln waste heat utilization system, the opening degrees of the valves are adjusted, and low-temperature corrosion is avoided; meanwhile, optimization of waste heat utilization is achieved to save energy, and the environment-friendly and energy-saving aims are achieved.

The invention discloses a product data pushing method and device, computer equipment and a storage medium. The method comprises the steps of judging whether the working state of a vehicle has changedor not; obtaining real-time environmental parameters of the vehicle if the working state of the vehicle has changed; calculating the real-time risk coefficient of a vehicle insurance type associated with the changed working state of the vehicle according to the real-time environmental parameters; calculating a cumulative value of the real-time risk coefficient of the vehicle insurance type withina specified period; and determining to purchase the vehicle insurance type if the cumulative value is greater than a risk threshold of the vehicle insurance type. When the cumulative value of the real-time risk coefficient of the vehicle is low, the insurance applicant can pay less or no vehicle insurance fee, thereby helping the insurance applicant to save the cost; and when the cumulative valueof the real-time risk coefficient of the vehicle is high, the insurance applicant can timely purchase the corresponding insurance type, thereby providing comprehensive insurance services for the vehicle, and providing a guarantee for the vehicle.

The invention provides a combined heat and power generation system. An exhaust steam regulating valve is arranged on an exhaust steam pumping pipeline and is in data connection with a programmable logic controller; a temperature sensor is arranged on a steam pipeline at the inlet of a steam-water heat exchanger; the temperature sensor is in data connection with the programmable logic controller and is used for measuring the temperature of steam entering the steam-water heat exchanger; and the programmable logic controller regulates the opening of the exhaust steam regulating valve by virtue of the steam temperature at the inlet of the steam-water heat exchanger. According to the system disclosed by the invention, the steam pumping quantity of exhaust steam and steam is automatically controlled according to the mixing temperature, so that the energy is saved, and the aims of environment friendliness and energy conservation are achieved.

The invention provides a diagnostic system and device of an automatic medicine selling machine. First information of a user is acquired, first demand information of the user is acquired according to the first information, wherein the first demand information comprises medicine information and illness state information, a first diagnostic device is determined according to the first demand information, the first diagnosis information is acquired according to auxiliary diagnosis of the first diagnostic device, and a first final medicine is acquired according to the first diagnosis information, the first demand information and the first information. According to the system and device, through acquiring identity information of the user, conventional diagnosis and treatment are conducted on theuser according to the demand of the user, so that the medicine information needed by the user can be diagnosed, the technical problem that an existing automatic medicine selling machine can only simply sell medicine but cannot provide simple diagnosis and recommend medicine for the user can be solved, so that the intelligent service of simply diagnosing the user and recommending the related medicine for the user can be achieved, and the technical effects of improving user experience, convenience and high efficiency are achieved.

The invention provides a radiator and a cogeneration system comprising the radiator. The radiator comprises a base tube and external fins, wherein the external fins are closed, each closed external fin comprises a fin body and a sealing piece sealing the fin body, and each closed fin is in the shape of a parabola from the lower portion of the base tube to the upper portion of the base tube. According to the intelligent cogeneration system, the structure of the radiator is optimized to enable heat exchanging efficiency to be maximized, and then energy is saved and the environment is protected.

The invention provides a control method for washing equipment, belongs to the technical field of washing equipment, and aims to solve the problems that a user cannot accurately master the allowance ofconsumables, the consumables are possibly used up and cannot be purchased in time, and the use experience of the user is influenced. The washing equipment comprises a consumable putting device, and the control method comprises the following steps of obtaining the total amount of consumables; obtaining the accumulated feeding amount of consumables fed by a consumable feeding device; and if the difference value between the total consumable amount and the accumulated consumable feeding amount is smaller than or equal to the preset value, enabling the washing equipment to send out prompt information. By means of the arrangement, when the consumables are about to be used up, the washing equipment can send out prompt information to remind a user to purchase the consumables in time, and the useexperience of the user is improved.

The invention provides a stationery processing method and a device thereof, computer equipment and a storage medium. The method comprises the following steps: receiving a stationery list sent by a teacher account; searching stationery in a parent asset database under the parent account; searching stationery in a student asset database under a student account associated with the parent account; ifthe stationery is found and the stationery is valid, combining the stationery in the parent asset database and the student asset database to serve as first target stationery; and removing the first target stationery from the stationery list to obtain the to-be-configured second target stationery so that the second target stationery is the stationery actually required by the user, the situation that students or parents repeatedly purchase the existing stationery is avoided, the cost is saved, the resource utilization efficiency is improved, meanwhile, students or parents can quickly obtain therequired stationery list determined from the stationery list and purchase the stationery list in time, so that normal learning of the students is guaranteed.
