Description
1. Field of the invention
The invention relates to the technical field of heat supply, in particular to hydraulic balance adjustment of a heat supply secondary network and charge management of heating users.
2. Background of the invention
The heating in winter in northern areas is a great civil problem, and the main two problems that solve of heat supply company at present are, firstly, will guarantee that all heat consumers can both obtain comfortable temperature, accomplish the most economic supply again simultaneously, also be exactly the balanced problem of pipe network, secondly how can manage heat consumer's heat charge effectively and collect and pay, guarantee the normal operation of company. At present, two methods are mainly adopted:
regulating and locking control by manual valve
Most heating power companies can only adjust the valves of users, especially existing building users, such as ball valves and gate valves, and then control the valves which can be locked and are not easy to open by the users to stop the users without paying arrearages, so that the valves are not good in adjustment linearity, the valves are not known to what degree, and the valves have no constant-current performance, and the influence of the flow of other users is interfered when the valves of one user are adjusted.
The self-operated flow control valve has good regulation performance, can know the given flow through the valve, also can keep constant flow without interference, has great progress compared with other valves, but has the main problems of manual regulation because the return water temperature is not known, the valve is regulated to a proper position even if the pipeline or the filter is blocked, and water cannot be found quickly, so that the main problems of manual regulation are as follows:
1. the adjustment is not fine, the room temperature and the return water temperature of the residents cannot be controlled at any time, and the adjustment balance is difficult to achieve.
2. The problems that the toll-free users are difficult to manage, for a plurality of stop-stop users and arrearage users, the valves can be unlocked by private short circuit of some users and payment failure through the relationship of human conditions, and the locked valves are forcibly opened by the users are frequent, so that the problems cannot be timely discovered by a heating power company. The home inspection of thousands of households is difficult to realize, and economic loss and negative effects are not small.
(II) control management is carried out by using electric remote transmission valve
With the development of the internet, a plurality of heating enterprises begin to use the remote electric valves at present. The ball valve or the flow valve balance valve is added with the electric actuator, and then the remote network control system and the platform achieve the effect of adjusting the valve opening and closing by the operation of a computer, and parameters such as pressure, temperature and the like can be uploaded together for analysis and research. Aims to close the valve for adjustment in the short time, thereby saving labor; secondly, the valve is not opened for charging, and the charging is convenient. The method can be used for solving a plurality of problems, such as regulating the flow control temperature according to the requirement to reduce waste, and remotely closing the valve for the non-payment user to facilitate the charging management. But many practical problems are brought to the implementation. Mainly comprises the following steps:
1. the investment is large; the cost of installing an electrically operated flow control valve for each household is relatively high. The uploading system of the valve body electric actuator has very high installation cost of a waterway circuit. Large area use is difficult to achieve without large investments.
2. The maintenance cost is high, besides the problems of the valve, the problems of out-of-control network communication, artificial damage, power failure, disconnection and the like of a power supply system need to be processed and maintained, and still very large human resources are needed. The inventor knows that the electric valve is installed to control the residents, so that the residents feel repugnance, and the problems that the electric head is dismantled to cut off the line occur. A small city also needs tens of thousands of households, and thus, the system is large in management and maintenance.
3. Influence the heat supply, many places all close the valve as the sharp weapon of charge management and control to the motorised valve, for control charge before the heating, who pays fee, gives who to open, and the problem is to pay fee to the heating time point thousands of user together and need open all valves at the same time, and all problems all concentrate on eruption in one or two days, and a time problem piles up and often encloses stifled heating power company.
4. The heat exchange station boiler room is not necessary to be adjusted for most years after the heat supply flow of each household is adjusted, and the water temperature of the heat exchange station boiler room can be well adjusted to adapt to weather changes after the flow of each household is well distributed. Therefore, each household is provided with a remote control regulating system, the actual use value is very low, from the aspect of charging control, the rate of defaulting and hot stealing households is at most 5%, and 5% of bad households are controlled according to 100% of investment, so that the situation that the defaulting and hot stealing households are not needed is high.
In recent years, national policies require that huge capital is invested in the existing building countries for heat metering transformation according to heat metering charge, so that people can save heat and actively save energy, but the problems of heat transfer among households, large heat consumption and difficult charge due to no heat at the top layer, and the like exist due to the fact that heat supply metering is very complicated. Yet another problem is that the heat meter only solves the metering problem and the hydraulic balance is not solved.
3. Summary of the invention
According to the problems and the defects, the invention provides a novel secondary network household regulation and control management method; a management and control method for pipe network balance and heat charge payment by using return water temperature monitoring; particularly, a temperature probe and a temperature collector are arranged on a water return pipeline at an inlet of a resident (or a unit) of a secondary network, the return water temperature of each household is uploaded to a control platform through an internet transmission system, and the return water temperature of each household can be adjusted to be basically consistent by using a manual valve to carry out targeted adjustment after the return water temperature is mastered, so that the effect of balancing and energy saving can be achieved; because the temperature display is carried out, the operator can easily adjust the valve to the proper position as if the eyes are grown, and the manual self-operated flow control valve is more convenient. Secondly, uploading the return water temperature to a computer platform can play an important role in monitoring charge management, especially for those who report and stop defaulting fees, key monitoring can be implemented, if the users are disconnected, the return water temperature is necessarily cold, if the users are hot, the users must be heated by bad means, the heating power company can find the temperature in time, necessary measures can be taken at any time to manage and reduce loss, the problems of people's feelings of opening valves, private opening valves and the like can be thoroughly solved, and the problem of unavailable charge is well solved.
4. Description of the drawings
Fig. 1 is a system diagram of a management and control method for pipe network balance and heat charge payment using return water temperature monitoring. The water supply system comprises a water supply pipe (1), a water return pipe (2), a locking valve (3), a temperature probe (4), an adjusting valve (5), a temperature collector (6), heating equipment (7), a data concentrator (8), a mobile base station (9) and a remote control platform (10).
5. Detailed description of the preferred embodiments
The invention is further explained by combining the attached drawings, as shown in the attached drawings, a temperature probe (4) for measuring the water temperature is screwed and installed on a water return pipe (2) at the inlet of a resident or a unit or on a regulating valve of the water return pipe to be connected with a temperature collector (6), the data collected by the temperature collector (6) is transmitted to a data concentrator (8) and then is transmitted to a remote control platform (10) through a mobile base station (9), and after normal heating, the temperature can be regulated according to the water return temperature by using a manual regulating valve for ensuring that each household can have a comfortable temperature. The specific adjusting method is that according to the temperature difference of the water supply and return of the whole heating system, the adjustment is carried out in a proper time period in a time period when the water supply temperature is basically consistent. When the water supply temperature is 45 ℃, the return water temperature of each household can be uniformly adjusted to 32 ℃, and if the return water temperature is higher than 32 ℃, the valve is closed to a small point and is opened to a large point. After the valve is adjusted, the lockable valve is locked to prevent the user from randomly adjusting the valve, and the valve can be closed and locked for residents who do not pay fees or stop heating. These households must be below the normal circulation temperature because of the non-circulating return water temperature.
The backwater temperature data uploaded by the network can be seen on a computer or a mobile phone, if the backwater temperature is abnormal, the problem of a heating system is certain, people can only be sent to solve the problem on site, intentionally defaulting and stopping households are reported, the households can be conveniently observed on a platform in a single row, and if the backwater temperature is not in a heating stopping state, heat stealing is possible, and the treatment can be carried out. Very few of these users are well regulated.
The valve for adjusting the flow can be a self-operated flow valve, a balance valve, a ball valve, a gate valve and the like, and the valves can be made into valves with locking functions, so that the valve for adjusting the flow and the valve with the locking function can be completely one valve or two valves in application. The temperature probe can be arranged on a valve for adjusting flow, and can also be directly inserted on a pipeline; the uploading temperature communication system can be a GPRS or other internet systems; the temperature collector can be powered by a wire or a battery. The temperature collector can be provided with a temperature display panel or not according to the requirement.
The practical significance of the invention is as follows:
1. the practical problem is solved at low cost, only the investment of uploading the return water temperature is relatively small, although manual regulation is not as labor-saving as electric regulation, the manual regulation is suitable for the fact that the flow of most residents is regulated well at one time and is not required to be regulated frequently or even is not required to be regulated for several years; charging problem it is also true that most users pay for money normally, and in doing so the problem is to use money on the blade.
2. The problem of hydraulic imbalance is solved purposefully, blind adjustment is very difficult if the return water temperature is not measured, and adjustment is simple and quick when the return water temperature is used as a basis, so that the problems of balanced heating and energy-saving heating are solved easily, and the labor cost is saved.
3. The fault rate is less, because the benefit that only survey return water temperature does not directly relate to the resident family, the artificial loss is less relatively, often many faults all are artificial and cause, for example tear electric head and cut off line etc. tear, so maintenance cost is lower. There are many methods available to lock the valve, which basically solve the locking problem.
4. The monitoring workload is small, and generally, after normal heating adjustment is in place, the heating adjustment does not need to be carried out again in a few years, so that monitoring does not need to be carried out by paying attention to normal residents, and for few unheated households of 2-5%, pipeline system problems such as blockage, insufficient radiators and the like are caused to a great extent, and the problems need to be handled by people on site. The number of the arrearage users who do not pay fees is limited to 5%, the arrearage users can be completely listed as key monitoring objects, and the workload is low. The heat stealing prevention is completely realized, and the problems of opening the valve to supply heat and the like under the condition of people are avoided. The temperature uploading device can be selectively installed, and the temperature uploading device is not required to be installed in each household, so that the cost can be reduced. At present, a plurality of valves capable of being locked are available, common residents are difficult to open, and the key problem is that people can find the valves in time when the residents are private.
